Simple Summary: The current approach to breast cancer screening, which is based on a person's age, overlooks individual-level differences in breast cancer risk. As a result, many people are over- or under-screened according to their actual risk of breast cancer. Risk-stratified breast screening may overcome the limitations of age-based screening, but there are still many knowledge gaps regarding how best to implement it in the population setting. This study will generate the first Canadian evidence on the adoption of breast cancer risk assessment in the population setting, to support the future implementation of risk-stratified breast cancer screening. This study demonstrated that, while risk assessment for risk-stratified screening at the population level is feasible, an equity lens must be considered in implementation to ensure cancer-screening disparities are not widened. Risk-stratified breast screening has been proposed as a strategy to overcome the limitations of age-based screening. A prospective cohort study was undertaken within the PERSPECTIVE I&I project, which will generate the first Canadian evidence on multifactorial breast cancer risk assessment in the population setting to inform the implementation of risk-stratified screening. Recruited females aged 40–69 unaffected by breast cancer, with a previous mammogram, underwent multifactorial breast cancer risk assessment. The adoption of multifactorial risk assessment, the effectiveness of methods for collecting risk factor information and the costs of risk assessment were examined. Associations between participant characteristics and study sites, as well as data collection methods, were assessed using logistic regression; all p-values are two-sided. Of the 4246 participants recruited, 88.4% completed a risk assessment, with 79.8%, 15.7% and 4.4% estimated at average, higher than average and high risk, respectively. The total per-participant cost for risk assessment was CAD 315. Participants who chose to provide risk factor information on paper/telephone (27.2%) vs. online were more likely to be older (p = 0.021), not born in Canada (p = 0.043), visible minorities (p = 0.01) and have a lower attained education (p < 0.0001) and perceived fair/poor health (p < 0.001). The 34.4% of participants requiring risk factor verification for missing/unusual values were more likely to be visible minorities (p = 0.009) and have a lower attained education (p ≤ 0.006). This study demonstrates the feasibility of risk assessment for risk-stratified screening at the population level. Implementation should incorporate an equity lens to ensure cancer-screening disparities are not widened. [ABSTRACT FROM AUTHOR]

Agricultural injuries remain a major concern in North America, with a fatal injury rate of 19.5 deaths per 100,000 workers in the United States. Numerous research efforts have sought to compile and analyze records of agricultural-related injuries and fatalities at a national level, utilizing resources, ranging from newspaper clippings and hospital records to Emergency Medical System (EMS) data, death certifications, surveys, and other multiple sources. Despite these extensive efforts, a comprehensive understanding of injury trends over extended time periods and across diverse types of data sources remains elusive, primarily due to the duration of data collection and the focus on specific subsets. This systematic review, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, consolidates and analyzes agricultural injury surveillance data from 48 eligible papers published between 1985 and 2022 to offer a holistic understanding of trends and challenges. These papers, reporting an average of 25,000 injuries each, were analyzed by database source type, injury severity, nature of injury, body part, source of injury, event/exposure, and age. One key finding is that the top source of injury or event/exposure depends on the chosen surveillance system and injury severity, underscoring the need of diverse data sources for a nuanced understanding of agricultural injuries. This study provides policymakers, researchers, and practitioners with crucial insights to bolster the development and analysis of surveillance systems in agricultural safety. The overarching aim is to address the pressing issue of agricultural injuries, contributing to a safer work environment and ultimately enhancing the overall well-being of individuals engaged in agriculture.

Recent debates surrounding intimate partner violence (IPV) have focused on its gender symmetry and gender-oriented nature. These debates center on findings from various data sources, like victimization or self-reported surveys and police-based reports. Data by Statistics Canada, from 1999 to 2014, has shown that the prevalence of IPV is similar for male and female victims, except for sexual assaults. However, there has been a paucity of studies on the severity and risk factors of IPV against men by female partners. Thus, this paper examines the severity of and risk factors for physical IPV against heterosexual men in Canada using the General Social Survey (Victimization) data of 2014. This study revealed that there is a symmetry in the experiences of physical violence between male and female victims. This study also revealed that male victims experience more severe violence than female victims. Using binary logistic regression analysis, years of dwelling together, the victim's age, childhood victimization, and marijuana use were found to predict physical IPV against heterosexual men. This paper concludes with suggestions about how these predicting factors can be used to identify male victims and the need for a more inclusive approach toward addressing IPV, which should include male victims.

Annual turnover of home care workers represents a huge loss of revenue and is a key source of inefficiency in the home health care industry. In this article, we propose a data-driven approach to monitor employee churn and to capture the evolution of employee intent to leave. Unlike most papers in the literature, we use machine learning techniques to analyze over 2 million visits in the US, Canada, and Australia between 2016 and 2019. Results show that the gap between the number of hours worked and in the contract is the most important factor to predict employee intent to leave, which means an employee should be given as many hours as requested in the contract to improve retention. Secondary results show that having diverse shift lengths and continuity in services and patients seem to be associated with less turnover. [ABSTRACT FROM AUTHOR]

Background: Low‐Risk Alcohol Drinking Guidelines (LRDGs) aim to reduce the harms caused by alcohol. However, considerable discrepancies exist in the 'low‐risk' thresholds employed by different countries. Argument/analysis: Drawing upon Canada's LRDGs update process, the current paper offers the following propositions for debate regarding the establishment of 'low‐risk' thresholds in national guidelines: (1) as an indicator of health loss, years of life lost (YLL) has several advantages that could make it more suitable for setting guidelines than deaths, premature deaths or disability adjusted years of life (DALYs) lost. (2) Presenting age‐specific guidelines may not be the most appropriate way of providing LRDGs. (3) Given past overemphasis on the so‐called protective effects of alcohol on health, presenting cause‐specific guidelines may not be appropriate compared with a 'whole health' effect derived from a weighted composite risk function comprising conditions that are causally related to alcohol consumption. (4) To help people reduce their alcohol use, presenting different risk zones associated with alcohol consumption instead of a single low risk threshold may be advantageous. Conclusions: National LRDGs should be based on years of life lost and should be neither age‐specific nor cause‐specific. We recommend using risk zones rather than a single drinking threshold to help people assess their own risk and encourage the adoption of behaviours with positive health impacts across the alcohol use spectrum.

Evidence that immigrants tend to be underserved by the health-care system in the hosting country is well documented. While the impacts of im/migration on health-care utilisation patterns have been addressed to some extent in the existing literature, the conventional approach tends to homogenise the experience of racialised and White immigrants, and the intersecting power axes of racialisation, immigration and old age have been largely overlooked. This paper aims to consolidate three macro theories of health/behaviours, including Bronfenbrenner's ecological theory, the World Health Organization's paradigm of social determinants of health and Andersen's Behavioral Model of Health Service Use, to develop and validate an integrated multilevel framework of health-care access tailored for racialised older immigrants. Guided by this framework, a narrative review of 35 Canadian studies was conducted. Findings reveal that racial minority immigrants' vulnerability in accessing health services are intrinsically linked to a complex interplay between racial-nativity status with numerous markers of power differences. These multilevel parameters range from socio-economic challenges, cross-cultural differences, labour and capital adequacy in the health sector, organisational accessibility and sensitivity, inter-sectoral policies, to societal values and ideology as forms of oppression. This review suggests that, counteracting a prevailing discourse of personal and cultural barriers to care, the multilevel framework is useful to inform upstream structural solutions to address power imbalances and to empower racialised immigrants in later life.

Background: Although previous research studies have defined several prognostic factors that affect cognitive‐communication performance in patients with all traumatic brain injury (TBI) severity, little is known about what variables are associated with cognitive‐communication impairment in complicated mild TBI (mTBI) specifically. Aims: To determine which demographic and trauma‐related factors are associated with cognitive‐communication performance in the early recovery phase of acute care following a complicated mTBI. Methods & Procedures: Demographic and accident‐related data as well as the scores on cognitive‐communication skill measures in the areas of auditory comprehension (complex ideational material subtest of the Boston Diagnostic Aphasia Examination), verbal reasoning (verbal absurdities subtest of the Detroit Test of Learning Aptitude), confrontation naming (short form of the Boston Naming Test), verbal fluency (semantic category and letter category naming), and conversational discourse (conversational checklist of the Protocole Montréal d'évaluation de la communication) were retrospectively collected from the medical records of 128 patients with complicated mTBI admitted to a tertiary care trauma hospital. Multiple linear regressions analyses were carried out on the variables sex, age, education level, Glasgow Coma Scale (GCS) score, lesion site and bilingualism. Outcomes & Results: Females performed better than males on letter‐category naming, while those more advanced in age performed worse on most cognitive‐communication measures. Patients with higher education achieved better confrontation and letter‐category naming, whereas reading comprehension results were worse with a lower GCS score. Bilingual individuals presented more difficulty in conversational discourse skills than those who spoke only one language. In terms of site of lesion, the presence of a right frontal injury was associated with worse auditory and reading comprehension and an occipital lesion was related to worse confrontation naming. Conclusions & Implications: Cognitive‐communication skills should be evaluated early in all patients with complicated mTBI, but especially in those who are advanced in age, those with fewer years of education and those who present with lower GCS scores, in order to determine rehabilitation needs. The findings of this study will allow acute care clinicians to better understand how various demographic and injury‐related factors affect cognitive‐communication skills after complicated mTBI and to better nuance the interpretation of their evaluation results in order to improve clinical care. Further study is required regarding the influence of lesion location, sex and bilingualism following complicated mTBI. What this paper addsWhat is already known on the subjectIn early acute recovery studies including all severity of TBI, cognitive‐communication performance was poorer in individuals with more advanced age, those with fewer years of education and with more severe TBI. It is not yet known which demographic and injury‐related variables predict cognitive‐communication performance after a complicated mTBI specifically.What this paper adds to existing knowledgeWe confirmed that age, level of education and TBI severity, as measured with the GCS score, were associated with some areas of cognitive‐communication performance for a group of patients in the acute stage of recovery from a complicated mTBI. We also identified that sex, bilingualism and site of lesion were new variables that show an influence on aspects of cognitive‐communication skills in this group of patients.What are the potential or actual clinical implications of this work?The findings of this study on prognostic factors in the case of complicated mTBI will help acute care clinicians to better understand evaluation results knowing the variables that can influence cognitive‐communication performance and to nuance the interpretation of these results with the goal of determining rehabilitation needs and enhancing clinical care.

The majority of refugees are children and youth and their integration and life-course transitions are a research priority. This paper examines the timing of refugee children and youths' entrance into the labour market and family formation (marriage/common law union and parenthood). It does so by examining how admission category, knowledge of a host country's official languages, and age at arrival shape their transition to adulthood. Using data from the Canadian Longitudinal Immigration Database and Heckman selection estimation, the paper finds minimal variation in refugee children and youths' entry into the labour market compared to children of other immigrant streams. It also finds that refugee children and youth start forming families at a younger age than children of economic class immigrants, but at an older age than family class children. The analysis also shows limited effects of knowledge of official language prior to arrival while age at arrival has a robust impact on their adulthood transitions. These findings shed light on the unique patterns of life-course transition among refugee children and youth and contribute to a better conceptualization of their experiences relative to children and youth of other immigrants.

Objectives: We investigated the contribution of five health domains to self-rated health (SRH) cross-sectionally and longitudinally and whether these contributions differ by gender or age. Methods: Employing dominance analyses, we quantified the contributions of functioning, diseases, pain, mental health, and behavior to both SRH at a point in time and for changes in SRH using data from the Canadian National Population Health Survey (NPHS, 1994–2011). Results: Cross-sectionally and longitudinally, functioning was the most important health domain, followed by diseases and pain. There were no meaningful differences in the ranking by gender while functioning, diseases, and pain were more relevant in older cohorts. Discussion: Functioning, diseases, and pain systematically were the most important health domains in both cross-sectional and longitudinal analyses. While these results held for women and men, they were more salient for older adults. This points to a gender-invariant but age-graded process, confirming previous research with European data.

Purpose – This study sought to gain a better understanding of the general life experiences of lesbian, gay, bisexual and transgender (LGBT) newcomer youth, situated within the broader context of their lives post-migration. The purpose of this paper is to explore the nature of various forms of oppression experienced by LGBT newcomers and offers recommendations for transforming services to better serve the complex needs of this marginalized population. Design/methodology/approach – The Teens Resisting Urban Trans/Homophobia (TRUTH) project was comprised of ten focus groups with 70 youth (aged 14-29) living in the Greater Toronto Area (GTA). Another three focus groups were conducted with 13 GTA service providers and teachers working with LGBT youth, in addition to one key informant interview. For this paper, the authors drew from a subset of the data including four newcomer-specific focus groups in which there were 39 youth who identified as refugees or immigrants, as well as key informant interviews with four youth (three of whom also participated in focus groups) and one service provider. Participants were asked about “what homophobia and transphobia meant to them”, “where they experienced it”, “in what forms”, and “how it impacted their daily lives”. Findings – The experiences of LGBT newcomer youth in this study involved a complex negotiation of multiple systems of oppression. Youth described experiences of homophobia and racism within interpersonal relationships, in the LGBT community, in their respective diasporic communities, in social service encounters and during the immigration/refugee process. Barriers for LGBT refugee youth included difficulties finding work and accessing health care, as well as the additional burden of proving their sexual orientation during refugee claimant hearings. Research limitations/implications – While the combination of focus groups and key informant interviews is a strength in this study, it also presents challenges for analysis. In focus groups, it is not always clear who is speaking; because of this, the authors were sometimes unable to differentiate between refugee and immigrant youth (or those without status) in our focus groups, making it often unclear which perspective or experience youth were speaking to. Another limitation was the dominance of the “cisgender gay male voice” in our conclusions. Lesbian and bisexual women were present in fewer numbers and the sample only included three trans youth. Practical implications – The findings reveal systemic discrimination on the basis of race and sexual orientation that illuminate injustices within Canadian society and systems that can enhance the efforts of those working in policy and service environments. Focused anti-homophobia and anti-racism training, and the implementation of policies designed to enhance accessibility, could improve service provision for newcomer LGBT youth. Furthermore, in order to facilitate a more just settlement process, a broader understanding of sexual identity, gender identity, and gender expression is required of the refugee claimant system. Originality/value – This study examines the experiences of youth in a large and complex, multicultural, and gay-friendly urban centre, thus providing timely and current data about the well-being of newcomer LGBT youth. As such, it is one of the first studies to offer some insights into the life issues and challenges post-migration of Canadian LGBT newcomer youth. [ABSTRACT FROM AUTHOR]

BACKGROUND: Ninety percent of smokers report having their first whole cigarette before the age of 19. Policies, such as youth access laws, are essential to prevent youth from becoming future smokers. In Canada, the Tobacco Act prohibits retailers from furnishing tobacco products to individuals under the age of 18. These laws can only be effective when retailers comply with them. This paper investigates the effect of retailer compliance on youth smoking behavior. METHODS: Data on individual smoking behavior in conjunction with provincial retailer compliance rates and cigarette prices for the years 1999–2005 were employed to examine the effects of retailer compliance on youth smoking participation and consumption. RESULTS: Both price and retailer compliance were significant predictors of smoking participation. A large portion of participants endorsed obtaining their cigarettes through social means. Price elasticity of demand for the overall sample was estimated to be −0.54. CONCLUSIONS: Consistent with previous literature, our results found that retailer compliance is an essential component to the successful implementation of youth access laws. Given that youth access laws and retailer compliance did not quell social access to cigarettes, there is an apparent need within schools and communities to reduce the social sale of tobacco products.

Purpose The purpose of this paper is to document the need for implementing a fall prevention strategy in an emergency department (ED). The paper also spells out the research process that led to approving an assessment tool for use in hospital outpatient services. Design/methodology/approach The fall risk assessment tool was based on the Morse Fall Scale. Gender mix and age above 65 and 80 years were assessed on six risk assessment variables using χ2 analyses. A logistic regression analysis and model were used to test predictor strength and relationships among variables. Findings In total, 5,371 (56.5 percent) geriatric outpatients were deemed to be at fall risk during the study. Women have a higher falls incidence in young and old age categories. Being on medications for patients above 80 years exposed both genders to equal fall risks. Regression analysis explained 73-98 percent of the variance in the six-variable tool. Originality/value Canadian quality and safe healthcare accreditation standards require that hospital staff develop and adhere to fall prevention policies. Anticipated physiological falls can be prevented by healthcare interventions, particularly with older people known to bear higher risk factors. An aging population is increasing healthcare volumes and medical challenges. Precautionary measures for patients with a vulnerable cognitive and physical status are essential for quality care.

Similar to their younger counterparts, older adults (age 60+) are increasingly turning to online dating sites to find potential romantic and sexual partners. In this paper, we draw upon qualitative data from a thematic analysis of 320 randomly selected online dating profiles posted by Canadian heterosexual older adults who self-identified as Asian, Black, Caucasian or Native American. In particular, we examined how the older adults' self-presentations varied according to race/ethnicity, age and gender, and how the language they used to describe themselves and their preferred potential partners reflected and reinforced idealised images of ageing. Our analysis identified five primary ways in which the older adults portrayed themselves. They depicted themselves as active and busy with cultural/artistic, social and adventurous activities; and also as physically healthy and intellectually engaged. Third, they emphasised the ways in which they were productive through work and volunteer activities. Fourth, they accentuated their positive approach to life, identifying themselves as happy, fun-loving and humorous individuals. Finally, they highlighted their personable characteristics, portraying themselves as trustworthy and caring. We discuss our findings with a particular focus on gender differences, drawing on literature on masculinity and femininity, and also look at capital and power relations by considering the online dating setting as a field in the Bourdieusian sense.

Background: Stroke survivors might perceive their quality of life (QoL) as being affected even years after onset. The purpose of this review was to go through the literature to identify factors related to QoL for persons with stroke in China and Western countries for possible similarities and differences in their respective cultural views. Method: A narrative literature review was conducted on the papers identified by searching PubMed, EBSCO/CINAHL, EMBASE, PsycINFO, China National Knowledge Infrastructure and Wanfang Data that published up to November 2016. Factors predicting QoL after stroke were extracted, and comparisons were made between Chinese and Western studies respecting cultural aspects. Results: A total of 43 articles were included in this review, with 31 conducted in Western countries and 12 in China. Predictors of QoL included Demographic factors: age, gender, marital status, education level, socioeconomic status; Clinically related factors: severity of stroke, physical function, depression/anxiety, cognitive impairment, incontinence and other comorbidities; Environmental factors: residential status, social support, social participation; and Individual factors: coping strategies and self‐perception. Being married and resident at home might be associated with the perception of QoL differently between Chinese and Western survivors. Conclusions: Most predictors of QoL in stroke survivors were the same in China and the Western countries. However, their QoL might be predicted differently regarding to the individualistic and collectivistic cultural differences. [ABSTRACT FROM AUTHOR]

This paper explores discourses of affirmative consent in sex education curriculum and policy. It traces the ways in which discourses of consent have emerged in sex education debates, focusing first on the activism of two young women in Ontario, Canada who lobbied the provincial government to include discussions of consent in a new Health and Physical Education (HPE) curriculum. Their activism is instructive for the ways in which their lobbying was eventually subsumed into the logics of curriculum, with learning outcomes and lesson plans taming the passion of their protest. As others see in sex education the answer to sexual violence, we cannot forget that sex education is, in part, a defence against passion, and that consent - once swallowed up by HPE - might also work to tame the unruliness of sexuality. Turning to age of consent laws - another arena where discourses of consent discipline the sexuality of young people - I ask how our pedagogical and legal address to sexuality paradoxically refuses its force. This is the central argument of this article - namely, that the concept of consent brings with it, into education, a procedural logic that misrecognises sexuality as a transparent, communicative, and rational experience and mistakes compliance for learning.

Purpose International studies indicate that offenders have higher rates of infectious diseases, chronic diseases, and physical disorders relative to the general population. Although social determinants of health have been found to affect the mental health of a population, less information is available regarding the impact of social determinants on physical health, especially among offenders. The purpose of this paper is to examine the relationship between social determinants and the physical health status of federal Canadian offenders. Design/methodology/approach The study included all men admitted to federal institutions between 1 April 2012 and 30 September 2012 ( n=2,273) who consented to the intake health assessment. Logistic regression analyses were used to explore whether age group, Aboriginal ancestry, and each of the individual social determinants significantly predicted a variety of health conditions. Findings The majority of men reported having a physical health condition and had experienced social determinants associated with adverse health outcomes, especially men of Aboriginal ancestry. Two social determinants factors in particular were consistently related to the health of offenders, a history of childhood abuse, and the use of social assistance. Research limitations/implications The study is limited to the use of self-report data. Additionally, the measures of social determinants of health were indicators taken from assessments that provided only rough estimates of the constructs rather than from established measures. Originality/value A better understanding of how these factors affect offenders can inform strategies to address correctional health issues and reduce the impact of chronic conditions through targeted correctional education and intervention programmes.

This paper considers the use of treatment resources in a health service system. The particular aspect of system use which is identified is resource absorption - excessive use by a small subset of users and unmet need by others. A dynamic stochastic model for health status with treatment interventions is formulated and the distribution of accumulated treatment time (service) is developed. The characterization of heavy tails in the distribution, the essential feature of resource absorption, is based on the Lorenz curve and an Index of Resource Absorption is defined for any feasible Lorenz curve. The index is applied to the use of psychiatric hospital resources in a Province of Canada. [ABSTRACT FROM AUTHOR]

Background: Stringent donor-screening criteria and legislation prohibiting payment for donor gametes have contributed to the radical decline of donor insemination (DI) using sperm provided by Canadian men. Thus, many individuals rely on imported sperm. This paper examines the feasibility of an altruistic sperm donation (ASD) program to meet the needs of Canadians. Methods: Using Canadian census data, published literature and expert opinions, two population-based, top-down mathematical models were developed to estimate the supply and demand for donor sperm and the feasibility of an ASD program. Results: It was estimated that 63 donors would pass Canadian screening criteria, which would provide 1,575 donations. The demand for DI by women was 7,866 samples (4,319 same sex couples, 1,287 single women and 2,260 heterosexual couples). Conclusion: Considerable effort would be necessary to create the required increase in awareness of the program and change in societal behaviour towards sperm donation for an ASD program to be feasible in Canada.

This paper examines how older men perceive, experience and internalise ageist prejudice in the context of their everyday lives. We draw on in-depth interviews with 29 community-dwelling Canadian men aged 65–89. Although one-third of our participants were unfamiliar with the term ageism, the majority felt that age-based discrimination was prevalent in Canadian society. Indicating that they themselves had not been personally subjected to ageism, the men considered age-based discrimination to be a socially distant problem. The men explained their perceived immunity to ageism in terms of their youthful attitudes and active lifestyles. The men identified three groups who they considered to be particularly vulnerable to age-based discrimination, namely women, older workers and frail elders residing in institutions. At the same time, the majority of our participants had internalised a variety of ageist and sexist stereotypes. Indeed, the men assumed that later life was inevitably a time of physical decline and dependence, and accepted as fact that older adults were grumpy, poor drivers, unable to learn new technologies and, in the case of older women, sexually unattractive. In this way, a tension existed between the men's assertion that ageism did not affect their lives and their own internalisation of ageist stereotypes. We consider our findings in relation to the theorising about ageism and hegemonic masculinity. [ABSTRACT FROM AUTHOR]

Medication-induced diabetes (MID) is common during induction therapy for pediatric acute lymphoblastic leukemia (ALL) and has potentially significant negative consequences. Reported risk factors for MID are variable with limited data comparing patients treated with standard-risk (SR) vs. high-risk (HR) regimens. This study aims to evaluate the incidence and risk factors for MID during induction in patients with ALL from the Maritimes over a 20-year period. We performed a retrospective single-center study of 262 patients (142 males, 120 females) diagnosed with ALL at IWK Health in Halifax, Nova Scotia, Canada, from 2000 to 2019. Older age, higher body mass index, greater central nervous system status, Trisomy 21, and prednisone steroid type were risk factors associated with MID in our cohort. HR patients developed significantly more complications than SR patients including MID and infection. Screening for MID should be routine during ALL induction treatment, particularly in those with HR disease. [ABSTRACT FROM AUTHOR]

Background: Hospitals and healthcare workers have been greatly impacted by the COVID-19 pandemic. The potential impacts upon the patient experience have been less documented, particularly in the pediatric setting. Our aim was to examine how parental experiences with their child's hospitalization varied during the COVID-19 pandemic at two children's hospitals in Alberta, Canada. Methods: A random sample of parents were surveyed within six weeks of their child's discharge from Alberta's two children's hospitals. Surveys were administered using the Alberta Pediatric Inpatient Experiences Survey (APIES) - a validated instrument used to assess parental experiences during their child's hospitalization. Surveys were linked with administrative inpatient records. Three cohorts were created based on hospital discharge date: Pre-COVID (Pre: April 2019 to March 2020), COVID year one (C1: April 2020 to March 2021), and COVID year two (C2: April 2021 to March 2022). We examined 48 survey questions, including four overall rating scales. Survey responses were Likert scales. These were transformed to normalized scores from 0 (worst) to 100 (best). Differences between cohorts were assessed using ANOVA and the post-hoc Tukey test. Results: A total of 3,611 surveys (1,314 Pre; 997 C1; 1,300 C2) were completed over the three-year period. Five questions showed differences between the Pre and C1 periods, six showed differences between Pre and C2, and 13 showed differences between C1 and C2. Among these questions, scores pre-COVID were lower than COVID year one, while results in COVID year two were lower than pre-COVID and COVID year one. Thirty-one survey questions showed no statistical differences between the three time periods. For the overall ratings, only hospital rating showed a difference in any of the periods (91.4 C1 vs. 90.2 C2). Overall ratings of doctors, nurses, and recommendation of the hospital to others showed no differences. Conclusion: This study showed that the experiences of parents during the first year of the COVID-19 pandemic were mildly better or comparable to historical results. This changed over the following year, where lower scores were reported on 13 questions. [ABSTRACT FROM AUTHOR]

Census-based deprivation indices have been widely used in Aotearoa/New Zealand, Canada and UK to measure area-based socio-economic inequalities. This paper examines the indicators used in census-based area deprivation indices using a political ecology approach. We question whether the current indicators of deprivation derived from census data are meaningful for the all age groups and minority groups in the population, with a particular focus on deprivation indicators used in New Zealand, Canada and the United Kingdom. We comparatively reviewed methodological papers and reports that describe the indicators of deprivation in Aotearoa/New Zealand, Canada and the UK from 1975 to 2014. We consider the relationship between the notion of standards of living and measurements of deprivation and explore how hegemonic cultural constructs are implicit in measures of deprivation that privilege a Eurocentric, ageist and gender normative construction of statistics. We argue for more political ecological analyses to studying the relationship between social inequalities, geographies, health inequities and political economy to transform structures of oppression and inequality. This requires turning the analytical gaze on the wealthy and privileged instead of defaulting into deficit models to account for inequality. Studies of deprivation and inequality would benefit from understanding the processes and operations of power in the (re)production of socio-economic and health inequities to inform holistic strategies for social justice.

Bans on retail tobacco displays, of the type proposed by New York's Mayor Bloomberg in March 2013, have been operative in several economies since 2001. Despite an enormous number of studies in public health journals using attitudinal data, we can find no econometric event studies of the type normally used in Economics. This paper attempts to fill that gap by using data from 13 cross sections of the annual Canadian Tobacco Use Monitoring Surveys. These data afford an ideal opportunity to study events of this type given that each of Canada's 10 provinces implemented display bans at various points between 2003 and 2009. Accordingly, we use difference-in-difference methods to study three behaviors following the introduction of bans: participation in smoking, the intensity of smoking and quit intentions. A critical element of the study concerns the treatment of contraband tobacco. Our estimates provide very little support for the hypothesis that behaviors changed following the bans.

Background: Historical changes in the nature of sedentary activities have been observed in other countries, but it is not clear if similar trends exist in Canada. It is also unclear how changes in the measurement of sedentary behaviour affects national estimates. Our objective is to document all sources and measures of sedentary behaviour from Canadian, nationally representative surveys, and report on selected estimates of time spent in sedentary activities. Lessons learned can benefit the wider international surveillance community. Methods: We describe and document all data sources of sedentary behaviour at the national level in Canada, and report on selected prevalence data from repeated cross-sectional surveys. We summarize amounts of total device-assessed sedentary time and self-reported sedentary activities (e.g., passive travel, leisure television, computer, video games, screen, and reading) by age group over time. Results: Nineteen national surveys were identified. Changes in questions and/or response categories precluded direct assessment of trends over time for some measures; however, certain trends were observed. Accelerometer-measured sedentary time, leisure reading (among those < 50 years) and television/video viewing in younger age groups have remained relatively stable (with a possible slight decline in television/video viewing). Time spent in passive travel and leisure computer and electronic device use appears to have increased. Television and video viewing appears to have increased in older adults while their leisure reading appears to have fallen. Conclusions: Changes in measurement of sedentary behaviour can affect estimates and reduce comparability over time. Total leisure screen use appears to have increased over time, reflecting the ways in which Canadians spend their free time and technological advances. The main public health message is the need for continued efforts to reduce leisure screen use, especially among youth and older adults. [ABSTRACT FROM AUTHOR]

Objective: Little is known about self-concept in adolescents with physical-mental comorbidity. This study investigated whether physical-mental comorbidity was associated with self-concept in adolescents and examined if adolescent age or sex moderated the association between physical-mental comorbidity and self-concept. Methods: Study data were obtained from the Multimorbidity in Youth across the Life-course (MY LIFE), an ongoing Canadian study of adolescents with chronic physical illness who were recruited from outpatient clinics at a pediatric hospital. A total of 116 adolescents aged ≥ 10 years provided self-reports on key measures. Results: Adolescents with comorbidity (n = 48) had lower self-concept scores on the Self-Determination Questionnaire (SDQ; d = 0.62) and Self-Perception Profile for Children (SPPC; d = 0.53) vs. adolescents without comorbidity (n = 68). An age × comorbidity status interaction was found and age-stratified models were computed to investigate this moderating effect of age. Amongst older adolescents, comorbidity was associated with lower SDQ (B = -2.55, p <.001), but this association was not found among younger adolescents (B = -0.29, p =.680). A similar effect was found for SPPC among older (B = -0.48, p =.001) and younger adolescents (B = 0.03, p =.842). Adolescent sex was not found to be a moderator. Conclusions: Physical-mental comorbidity in adolescence was associated with lower self-concept and this association was moderated by age—differences between adolescents with vs. without comorbidity were greater for older adolescents and were clinically relevant. Opportunities to support positive self-perceptions for adolescents with comorbidity are warranted, especially when planning the transition from pediatric to adult health services.

This article analyses and compares disability policies for working-age individuals in Canada with a focus on the mode of policy provision and type of measure to determine the degree to which direct funding is used in this country. To consider policy diversity in this federal system, policies are compared using a mixed-methods approach. Using quantitative methods, federal, provincial and territorial policies are first compared using hierarchical cluster analysis. This provides evidence of three distinct clusters in Canada according to policy provision and measure type. In a second, qualitative analysis, the disability strategies of four provinces' (British Columbia, Ontario, Newfoundland and Labrador and Quebec) are compared, to determine over arching policy orientations. Findings indicate that policy provision in Canada largely favours money over services. Furthermore, most provinces emphasize either health or integration measures over substantive measures. Despite these commonalities, significant variation persists across Canada. This extends to poverty and disability reduction strategies with two of the four provinces having a broader orientation while the other two provinces focus specifically on employment as a means of social inclusion. The article concludes with a discussion on the state of employment policies for individuals with a disability in Canada. [ABSTRACT FROM AUTHOR]

Simple Summary: Cutaneous melanoma is a deadly form of skin cancer, and its incidence rate continues to increase in Canada. Cutaneous melanoma has many modifiable risk factors, making it a preventable disease. The purpose of this study is to gain valuable information on sun exposure, sun protection and level of worry for cutaneous melanoma in Atlantic Canada. We compare these findings between provinces with a high incidence of cutaneous melanoma against those with a low incidence, as well as between various demographic groups. Our study was able to identify significant differences across multiple variables between these groups. These findings will help guide future public health efforts aiming at preventing cutaneous melanoma and reducing its incidence in our communities. Background: The incidence of cutaneous melanoma (CM) is increasing at an alarming rate in Canada and elsewhere around the world. Significant regional differences in CM incidence have been identified in Atlantic provinces. The goal of this study is to compare ultraviolet exposure, sun protective behaviours, level of worry and baseline CM knowledge in provinces with a high versus low incidence of CM as well, as between various demographic groups. Methods: A cross-sectional survey study was conducted in Atlantic provinces between July 2020 and August 2022. All participants aged ≥ 16 years with a completed survey were eligible. Survey responses were summarized using frequency counts, percentages, and means. Two-sided Z-tests for equality of proportions and logistic regression models were used to compare the survey results between geographic and demographic groups. Results: In total, 7861 participants were included (28.0% men; mean age 61.3 years; response rate 28%). Our results (gender- and age-adjusted odds ratio, 95% confidence interval) show that high-incidence provinces for CM (Prince Edward Island and Nova Scotia) had significantly more sunburns (OR 2.00, 1.72–2.31), total sun exposure (OR 2.05, 1.68–2.50), recreational sun exposure (OR 1.95, 1.61–2.35) and tans (OR 1.77, 1.53–2.05) than individuals in low-incidence provinces (Newfoundland and Labrador). However, individuals in high-incidence provinces displayed more protective behaviors: there were less tanning bed users (OR 0.82, 0.71–0.95), they checked their skin more frequently for new moles (OR 1.26, 1.06–1.51) and practiced more sun protection overall. Additional analyses are presented based on education, income, sexual orientation and gender. Discussion: These findings suggest that future efforts aimed at reducing the CM burden in Atlantic Canada should be tailored for target geographic and/or demographic groups. Limitations: the study participants are not representative of the population in Atlantic Canada due to recruitment strategies. [ABSTRACT FROM AUTHOR]

This article examines legal discourses on precarious status children in Canada over the last decade. Drawing on different theoretical frameworks and taking into account laws and court decisions, the paper will examine the way in which precarious status children are regarded as powerless subjects in need of protection and as threatening others. The article argues that these two apparently contrasting discourses are embedded within specific socio-historical constructions of childhood and children's citizenship which deny and limit their agency and conceive of their claim to membership as illegitimate. In the case of precarious status children, illegality and citizenship need to be redefined in a developmental perspective, questioning the potential risks associated with prevalent moral and social assumptions on childhood.

Research on informal care-giving has largely neglected the contributions of non-kin carers. This paper investigated the characteristics and contributions of non-kin who care for older adults with a long-term health problem, and investigated friends and neighbours as distinct categories of care providers. Using data from 324 non-kin carers in the 1996 General Social Survey of Canada, this study compared individual and relationship characteristics, care tasks and amount of care provided for the two groups. Interpersonal and socio-demographic characteristics were investigated as mediators of potential differences between friends and neighbours in patterns of care. Results demonstrate that friend and neighbour carers differed on age, marital status, geographical proximity and relationship closeness. Friends were more likely than neighbours to assist with personal care, bills and banking, and transportation. Neighbours were more likely to assist with home maintenance. Friends provided assistance with a greater number of tasks and provided more hours of care per week, suggesting a more prominent role in the care of non-kin than neighbours. Age, income, a minor child in the household, proximity and relationship closeness significantly predicted amount of care provided, and relationship closeness largely explained differences between friends and neighbours. Future research on informal care-giving can build on the findings that distinguish friend and neighbour carers to further discriminate the dynamics of non-kin care. [ABSTRACT FROM PUBLISHER]

Abstract: One of the core primary care reform initiatives seen across provinces in Canada is the introduction of inter-professional primary healthcare teams in which family physicians are encouraged to collaborate with other health professionals. Although a higher proportion of physicians are collaborating with various health professionals now compared to the previous decade, a substantial number of physicians still do not work in a collaborative setting. The objective of this paper is to examine the age, period and cohort effects of Canadian family physicians’ decisions to collaborate with seven types of health professionals: specialists, nurse practitioners, nurses, dieticians, physiotherapists, psychologists and occupational therapists. To this end, this paper employs a multivariate probit model consisting of seven equations and a cross-classified fixed-effects strategy to explain the collaborative decisions of family physicians. Utilizing three cross-sectional physician surveys from Canada over the 2001–2007 period, cohorts are defined over five-year intervals according to their year of graduation from medical school. We find that newer cohorts of physicians are more likely to collaborate with dieticians, physiotherapists, psychologists and occupational therapists; newer female cohorts are more likely to collaborate with nurses while newer male cohorts are less likely to collaborate with nurses but more likely to collaborate with specialists. Older physicians are more likely to collaborate with specialists, physiotherapists, psychologists, and occupational therapists; the age effect for nurses is U-shaped for male physicians while it is inverse U-shaped for females. Family physicians are collaborating more with all seven health professionals in 2004 and 2007 compared to 2001. Belonging to a group practice has a largely positive influence on collaborations; and being paid by a fee-for-service remuneration scheme exerts a negative influence on collaboration, ceteris paribus. The findings suggest that combining a non-fee-for-service remuneration arrangement with a group practice structure would facilitate effective collaboration. [Copyright &y& Elsevier]

Scholars and practitioners from multiple perspectives, including developmental science, sociology, business, medicine, and public health, have considered the implications of employment for young people. We summarize a series of meetings designed to synthesize information from these perspectives and derive recommendations to guide research, practice, and policy with a focus on young worker safety and health. During the first three meetings, participants from the United States and Canada considered invited white papers addressing developmental issues, public health data and findings, as well as programmatic advances and evaluation needs. At the final meeting, the participants recommended both research and policy directions to advance understanding and improve young worker safety. [ABSTRACT FROM AUTHOR]

Attitudes drive practice, perhaps more than evidence The objective of this study was to determine if the new generation of Canadian obstetricians has attitudes differing from those of their predecessors. Employing a cross-sectional, Internet, and paper-based survey, we conducted an in-depth study of obstetricians responding to the Canadian National Maternity Care Attitudes Survey. Of the 800 Canadian obstetricians providing intrapartum care, 549 (68.6%) responded. Participants were stratified by age less than or equal to 40 years compared with those over 40 years; 81 percent of those 40 years or younger were women versus 40 percent over 40 years of age. Younger obstetricians were significantly more likely to favor use of routine epidural analgesia and believed that it did not interfere with labor or lead to instrumentation; were more concerned and feared the perineal and pelvic floor consequences of vaginal birth compared with cesarean section; and were significantly less supportive of vaginal birth after prior cesarean section, home birth, birth plans, routine episiotomy, and routine electronic fetal monitoring as providing maternal or fetal benefits. They were less positive than the older generation about a range of approaches to reducing the cesarean section rate, the importance of maternal choice and role in their own birth, and peer review, and they were more likely to believe that women having a cesarean section were not missing an important experience. No significant generational differences were found for ambivalent attitudes to vaginal breech birth. Younger obstetricians were more evidence-based for some issues and less for others. In general younger obstetricians were more supportive of the role of birth technology in normal birth, including routine epidural analgesia, and they were less appreciative of the role of women in their own birth. They saw cesarean section as a solution to many perceived labor and birth problems. Results suggest a need to examine how obstetricians acquire their favorable attitudes to birth technology in normal birth. (BIRTH 38:2 June 2011) [ABSTRACT FROM AUTHOR]

INTRODUCTION Electronic cigarette (e-cigarette) use among youth is common, and so efforts to regulate its use and availability are continually being made. The school environment represents an important domain for advancing health policy among youth populations. This study examines the impact of school-based e-cigarette control policies on student e-cigarette use in the context of a natural experiment. METHODS Using three years of longitudinal student and school level data (2013/2014 to 2015/2016), from a sample of 69 secondary schools in Ontario, Canada, a generalized estimating equation approach examined the impact of school-based e-cigarette control policy changes on the prevalence of youth e-cigarette use. The main outcome of interest was current e-cigarette use, while covariates included age, gender, ethnicity, and amount of spending money in dollars per week the student has. Tests of proportion (t-tests) were used to examine whether there were any significant differences in the changes for each intervention school relative to the sample of schools that report no changes in school-level e-cigarette control policies. RESULTS Estimates from the generalized estimating equation approach suggest that students had lower odds of using e-cigarettes in schools where an e-cigarette control policy was implemented. That is, the e-cigarette control policy decreased the adjusted odds of being an e-cigarette user (OR=0.68; 95% CI: 0.48-0.97). Examining school-specific impact, at four of six schools that had an e-cigarette control policy, the ban on the use of e-cigarettes may have lowered the prevalence of e-cigarette use. CONCLUSIONS This is the first study to use longitudinal data to study school-level e-cigarette use and the impact of e-cigarette control policy. These results provide new evidence that school-level policies banning the use of e-cigarettes on school property may be effective in reducing e-cigarette use (or preventing it) in their current form, as seen in this natural experiment.

This paper presents a mathematical model to show the conditions in which age standardization can be used to summarize age-specific rates for comparison purposes over calendar time. It shows that the conditions for valid comparison depend on the type of measure used for comparison, that is, difference, ratio, or percent change. If the measure for comparison is a difference of the standardized rates at two time points, then the age-specific rates need to maintain a constant rate difference over time for the comparison to be valid. If the measure for comparison is a ratio or percent change of the standardized rates at two time points, then the age-specific rates need to maintain a constant rate ratio over time for the comparison to be valid. Since in reality, as shown by our Canadian empirical data, age-specific rates do not always maintain a consistent pattern over time, it is recommended that one should always stratify the data to look at patterns of age-specific rates before applying age standardization.

There has been ongoing national discourse about barriers to mental health care services in Canada. The purpose of the study is to better understand these barriers, with a focus on Canadians of color. To that end, this study surveyed 1501 adults representative of the general population, collected by the Angus Reid Institute. Over half of the respondents had sought out mental health care and experienced barriers to access. People of color (visible minorities and Indigenous people) had more difficulty accessing care, as did younger adults and those with lower incomes. The most common difficulties were largely structural: long waitlists (62%), financial barriers (58%), lack of resources/professionals in the area (47%), difficulty finding specialists (41%), and difficulty accessing in-person care during the pandemic (34%). Many noted negative experiences with mental health professionals (35%). More English-speaking than French-speaking Canadians reported barriers to care overall. Race/ethnicity was related to difficulties when trying to access mental health care, as many could not find someone of the same group (25% of Black respondents), someone who spoke their preferred language (22% of South Asian respondents), or they had prior negative experiences (50% of Indigenous respondents). We discuss the implications of these findings, including the critical need to increase the supply and diversity of mental health providers across Canada. This study is one of the first to provide quantitative data on the perceived barriers faced by Canadians in accessing mental health care while exploring the role of language, race, and ethnicity as variables that may influence access.

Abstract Increases in youth vaping rates and concerns of a new generation of nicotine addicts recently prompted an increase in the federal minimum legal purchase age (MLPA) for tobacco products, including e-cigarettes, to 21 years. This study presents the first regression discontinuity evidence on the effectiveness of e-cigarette MLPA laws. Using data on 12th graders from Monitoring the Future, we obtain robust evidence that federal and state age 18 MLPAs decreased underage e-cigarette use by 15–20 percent and frequent use by 20–40 percent. These findings suggest that the age 21 federal MLPA could meaningfully reduce e-cigarette use among 18- to 20-year-olds. [ABSTRACT FROM AUTHOR]

Background: The nature of the Canadian population 65+ has changed considerably over the past several decades. They comprise a larger proportion of the population, are better educated, and are wealthier than previous generations. We estimate the contributions of chronological aging, temporal periods, and birth cohort effects on the trends in the major depressive episode (MDE) prevalence among Canadian seniors from 1994/1995 to 2017/2018. Methods: Using data from two sets of national health surveys, the National Population Health Survey (NPHS) and the Canadian Community Health Survey (CCHS). Pooled data on 150,246 survey respondents aged 65+ from 16 repeated cross-sectional surveys are included. Hierarchical regression age-period-cohort models were used to visualize the linear and non-linear effects of age, period, and cohort trends in late-life depression. Results: We found that: the prevalence of MDE in later life fluctuated non-significantly during the study time period; the probability of developing MDE declined with increasing age from 65 to 80+ (β = −.32, p =.027). The significant quadratic birth cohort predictor showed a non-linear increasing association with the prevalence of MDE from the earlier to later-born cohorts (β =.01, p =.049). We also found that females 65+ were consistently more likely to be depressed than males 65+ (β =.47, p =.007). The significantly negative "age × female" interaction shows that age exerts a greater effect on females' probability of developing MDE than males (β = −.09, p =.011). There were no consistent significant period effects but there were peaks in prevalence around 2001, 2008, and 2012 which corresponded to some recent historical events. Our moderation analysis documents that lower levels of education significantly contributed to the higher rates of depression among cohorts born earlier in the 20th century. Conclusions: Our findings show the presence of strong chronological age and cohort effects and weaker period effects on the prevalence of late-life depression in Canadian seniors.

Generally, substance misuse is associated with young people, however there is a growing concern on the rates of prescription drug misuse among older adults. This review aims to assess the extent of the prescription drug misuse problem among older adult Canadians. A scoping review was carried out following the PRISMA guidelines. PubMed, PsycINFO, MEDLINE and Google scholar databases were used to carry out the search. Retrieved articles were assessed for relevance against the inclusion and exclusion criteria. Results were reviewed to identify major findings. 840 abstracts were reviewed, and 13 articles were included in the scoping review. Key findings are as follows: (1) misuse of prescription drugs is more prevalent among users who used other substances, (2) prescription misuse is positively associated with cannabis use, (3) adults exposed to prescription drugs at hospitals are likely to misuse prescription drugs in the future, (4) prescription drug misuse negatively influences the continuation of medication-assisted treatment, (5) reasons for non-medical prescription drug use include sleep, pain, stress, and nausea. Prescription drug misuse is a problem among adults, but little attention is paid to older adults. To better understand this problem and create age-specific interventions more research in the area of prescription drug misuse among older adults and motives for misuse needs to be thoroughly studied.

Pregnant refugee patients are especially vulnerable to adverse perinatal outcomes. Detailed characterization of this heterogenous population will identify risk factors and thus guide contextualized initiatives for improved patient care. A retrospective cohort study of obstetrical refugee patients at a tertiary-care hospital in Toronto, Ontario. Of 196 pregnant refugees, 48% were fluent English speaking, 57% had poor social support, and 42% lived in a shelter. Eighty-seven percent started prenatal care after the first trimester, which was associated with delivery of a large-for-gestational-age infant (p = 0.043). Sixteen percent experienced family violence, which was associated with poor fetal aggregate outcomes (p = 0.03). There were significantly higher rates of pre-eclampsia and Cesarean sections in refugee versus non-refugee patients (p < 0.05). Pregnant refugees are at risk for psychosocial challenges and experience significantly worse obstetrical outcomes compared with non-refugees. Quality improvement initiatives should focus on access to early prenatal care, stable housing, and support for victims of family violence. [ABSTRACT FROM AUTHOR]

Summary: Background: Many countries, including Canada, are considering regulations to restrict food and beverage marketing to children. However, little evidence is available outside of the US on how marketing exposure differs across sociodemographic subgroups. Objective: To investigate potential associations between child and adolescent sociodemographic characteristics and exposure to food and beverage marketing in Canada. Methods: Participants (n = 3780) aged 10–17 self‐reported exposure to food and beverage marketing across food categories, locations and marketing techniques. Logistic regression models tested relationships between sociodemographics (age, sex, ethnicity and income adequacy) and marketing exposure. Results: Among other differences identified, 13–17 years old were more likely than 10–12 years old to report seeing unhealthy food marketing online. Girls were more likely than boys to see such marketing online and in retail settings, while boys were more likely to see it in video games. Minority ethnicities (including Indigenous youth) and respondents with lower income adequacy generally reported more exposure than White and higher income respondents, respectively. Conclusions: This study highlights important differences in marketing exposure among youth of different sociodemographic groups in Canada, including greater exposure to marketing among those most disadvantaged and emphasizes the essential need to consider food marketing across equity groups when developing restrictions on marketing to kids.

Background: The Life-Space Assessment (LSA) can compliment traditional physical performance measures of mobility by accounting for the interaction between individuals and their environment. However, there are no studies that have generated percentile curves showing sex-stratified reference values in a large population-based sample of community-dwelling adults, making its interpretation difficult. Therefore, this study aimed to establish sex-stratified reference values for the LSA in middle-aged and older Canadians. Methods: Baseline data for participants aged 45–84 years old from the Canadian Longitudinal Study on Aging (CLSA) were used (n = 22,154). Quantile regression was used to estimate specific percentiles, with age as the independent variable and LSA scores as the dependent variable. Models were run for the whole sample, then separately for males and females. The models were cross-validated to assess their reliability. CLSA inflation and analytic weights were applied. Results: On average, the sample was 62.5 ± 10.0 y.o. (51.1% males), with a weighted mean LSA score of 89.2 ± 17.0. There was also a decrease in LSA scores with age, where scores were lower for older age groups compared to younger groups, and LSA scores were lower for females relative to males. Discussion and conclusions: Reference data will aid in interpreting, comparing, and making inferences related to LSA scores obtained in clinical and research settings for Canadian adults.

"This paper proposes to introduce the migration component into the stable population model and examine the stability of the age distribution. The analysis [is restricted] to one sex as [has been] done by others." The model is applied to Canadian data., (excerpt)

"This paper analyses the prospects for age distribution in Canada through 2036, based on today's age structure and expected trends in fertility and international migration. Simulating these two demographic components at extreme levels shows that tomorrow's aging is already built into the current age distribution, which is heavily marked by the post-war baby boom and the following persistent baby bust, and that neither fertility nor immigration can be seen as effective adjustment mechanisms for the changing age composition of Canada. Population projections using the component method are applied along with an age-specific growth-rate analysis.", (excerpt)
