The purpose of this study was to evaluate gender-specific differences in prevalence and risk factors for alcohol, tobacco, and marijuana use among 50- to 65-year-old Jamaicans. We performed secondary analysis of the 2016 Jamaica National Drug Use Prevalence Survey. The dependent variables were self-reported use of tobacco, alcohol, and marijuana in the 30 days before the survey. The independent variables included general, socioeconomic, and community characteristics and concomitant substance use. Gender-stratified multiple Poisson regressions were conducted. The survey included 1,099 individuals aged 50-65 years; 50.3% were men. Reported use was significantly higher in men than in women: alcohol (54.9% vs. 17.8%), marijuana (22.4% vs. 2.2%), and tobacco (19.2% vs. 3.9%). High income was associated with alcohol use in women, whereas low and middle incomes were associated with marijuana use among men. Being employed was associated with tobacco use among women and with alcohol use among men. Rural residence was associated with alcohol use in women and with marijuana use in men. High neighborhood disorder was associated with tobacco use in women and alcohol and marijuana use in men. Concomitant substance use increased the likelihood of alcohol, tobacco, and marijuana use in men and women. We conclude that gender-sensitive strategies to substance use prevention and treatment are needed in Jamaica.

Dementia is a leading global cause of morbidity and mortality. Evidence suggests that tackling modifiable lifecourse risk factors could prevent or delay a significant proportion of cases. Population- and community-based approaches change societal conditions such that everyone across a given community is more likely to live more healthily. We systematically reviewed economic studies of population- and community-based interventions to reduce modifiable lifecourse risk factors for dementia. We searched Medline, EMBASE, Web of Science, CINAHL, PsycInfo, Scopus, Econlit, ERIC, the British Education Index, and Google, on 03/03/2022. We included cost-effectiveness, cost-benefit, and cost-utility studies, provided that the direct outcome of the intervention was a modifiable risk factor for dementia, and was measured empirically. Quality appraisal was completed using the Consensus on Health Economic Criteria checklist. A narrative synthesis was performed. We included 45 studies, from 22,749 records identified. Included studies targeted smoking (n = 15), education (n = 10), physical inactivity (n = 9), obesity (n = 5), air pollution (n = 2), traumatic brain injury (n = 1), and multiple risk factors (n = 3). Intervention designs included changing the physical/food environment (n = 13), mass media programmes (n = 11), reducing financial barriers or increasing resources (n = 10), whole-community approaches (n = 6), and legislative change (n = 3). Overall, interventions were highly cost-effective and/or cost-saving, particularly those targeting smoking, educational attainment, and physical inactivity. Effects were observed in high- (e.g. USA and UK) and low- and middle-income (e.g. Mexico, Tanzania, Thailand) countries. Further research into the direct effects of targeting these risk factors on future dementia prevalence will have important economic, social and policy implications.

Research on the association between migration and health among nonmigrant family in Jamaica is limited. Data from the 2012 Jamaica Return(ed) Migrants Study (N = 621) and weighted regression models were used to investigate the association between migration and health among left-behind women (n = 323) and men (n = 298) in Jamaica. Compared to women whose children lived in Jamaica, women who had a child abroad reported lower odds of good mental health (OR = 0.46, 95% CI 0.21, 0.97). Men in this situation were less satisfied with their lives (b = − 2.370, p = 0.031). Women reported better physical (b = − 2.113, p = 0.010) and mental (b = − 3.119, p = 0.039) health scores when a parent, but not a grandparent, lived abroad. Men with a migrant spouse/partner reported significantly more physical illness symptoms than men whose spouse/partner lived in Jamaica (b = 3.215, p = 0.013). Migration exerts disparate health impacts on left-behind family and may disrupt social relationships.

Purpose To identify staff and participants perspectives of best practices that facilitate achieving enrollment and retention targets in biomedical cohort studies in Caribbean populations. Methods Eight focus group discussions (FGDs) were held with research stakeholders including research (i) nurses/study supervisors, (ii) field staff/data collectors, and (iii) rural and urban participants of the Third Jamaica Health and Lifestyle Survey (a national NCD risk factor survey with biospecimen collection) to capture qualitative data on experiences with recruitment, training, retention challenges and potential solutions or strategies for strengthening future efforts. Results Our findings indicate that trained, experienced study staff with good interpersonal communication skills enhanced the proficiency of field operations and attracted study participants. Targeted community and stakeholder engagement alongside strong support from the coordinating center increased the reach and efficiency of the data collectors. Timely participant feedback, gender-appropriate approaches, and socioeconomic balance enhanced equitable enrollment and retention of participants of cohort studies particularly the hard to reach groups. Conclusion Well-functioning research teams using traditional and social media promotion, applying gender-appropriate and personalized approaches together with strategies for reaching the less accessible socioeconomic groups, are effective for recruiting and retaining members of a Caribbean cohort. These strategies may also enhance the recruitment of other Black populations in the Diaspora including the US and Caribbean into biomedical studies including cancer research.

STRiDE was an ambitious four-year project in seven countries aiming to build capacity around generating and using research to support the development of policies to improve quality of life of people with dementia and their carers. The project’s innovative approach combined rigorous academic research and hands-on civil society advocacy. This paper explores the project’s unique strategy for policy change and compiles case-studies from several of the STRiDE countries. Finally, we share lessons learned and next steps to keep momentum for policy change going in each of these countries – and beyond.

Background and Objectives Understanding the influences of marginalized cultural and social identities as experienced by the African Caribbean diaspora within the context of dementia care is essential to minimize the gaps in current practice and policy in the health care setting. This study explores the impact of marginalized identities upon the meaning-making process, access to services and experience of care provisions through a scoping review and consultancy exercises with key stakeholders. Research Design Fourteen databases were searched using key terms. Primary studies in English, any year, study design, and country of origin were eligible. Titles, abstracts, and full texts were screened for inclusion and data were extracted in stages. Thematic analysis was performed and the findings were discussed in a series of consultation meetings with people with dementia, carers, and health care professionals in Manchester (United Kingdom) and Jamaica. Results The scoping review retrieved n = 1,989 research articles. Nineteen were included, most were qualitative (n = 14), 3 quantitative, and 2 mixed-method. The findings revealed limited insight into cultural and multiple individual identities in explaining conceptualization and service access. Consultation meetings confirmed these findings and highlighted differences in health care services and systems in the United Kingdom and Jamaica. Discussion and Implications This study suggests there is a complex interaction of sociocultural processes that marginalize African Caribbean persons in and across various national settings within the context of dementia care. The study highlights the importance of acknowledging and addressing how prevalent racialized- and class-based divides and related marginalized social locations are reflected in inequities in access to and use of dementia services.

Involving people living with dementia in service design and planning has become more common in high-income countries. It remains rare in low- and middle-income countries where two-thirds of the world’s people with dementia live. In this commentary article, we explore the barriers to inclusion of people living with dementia in planning in low- and middle-income countries and make a case for the inclusion of people living with dementia in care and service planning. We suggest how this can be done at individual, community or national and state level using the following principles: 1) respecting the rights of people living with dementia to self-determination; 2) valuing people living with dementia’s unique understanding of dementia; 3) creating a culture of active inclusion which creates a space for people living with dementia to participate and 4) ensuring appropriate accommodations are in place to maximise participation.

Cross-cultural adaptation is an important part of using validated questionnaires across countries and settings. Here we describe the cross-cultural process adopted in the STRiDE (STrengthening Responses to dementia in DEveloping countries) program.\ud \ud We adopted a cross-cultural adaptation process including forward translation, back translations, and cognitive interviews of the STRiDE toolkit. In total, 50 older adults and 41 carers across sites in Indonesia and South Africa participated in cognitive interviews; field notes and verbatim quotes are reported.\ud \ud We describe the cross-cultural adaptation process of the STRiDE toolkit. During the process, issues were identified with the translated toolkit, including aspects related to cultural appropriateness, terminology equivalence, and timings.\ud \ud The data demonstrate that a rigorous, yet pragmatic, cross-cultural adaptation process can be achieved even with limited resources. Our process should help the design and conduct of future dementia research in various contexts.

Background Subjective cognitive decline (SCD) is present in the early stage of preclinical Alzheimer’s disease (AD) and is associated with an increased risk of further cognitive decline and AD dementia later in life. Early detection of at-risk groups with subjective complaints is critical for targeted dementia prevention at the earliest. Accurate assessment of SCD is crucial. However, current measures lack important psychometric evaluations and or reporting. Objectives To systematically evaluate measurement properties of self-reported outcome measures (PROMs) used to assess SCD in the older adult population with or at risk of AD. Methods and analysis We used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols 2015 Checklist for reporting. We conducted a literature search, screened, and included validation studies of SCD based on self-reported questionnaires from both population-based and clinical studies, conducted in older adults (≥ 55). We critically appraised the included primary studies using the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. Results Sixteen studies met the inclusion criteria. The included studies reported psychometric properties of 17 SCD self-reported questionnaires. We extracted data on the structural validity, internal consistency, test-retest reliability, and cross-cultural validity and found a widespread proneness to bias across studies, and a marked heterogeneity is assessed and reported measurement properties that prevented the consolidation of results. Conclusion Our findings suggest that available SCD questionnaires lack content validity evaluation. Currently available measurements of SCD lack development and validation standards. Further work is needed to develop and validate SCD self-reported measurement with good quality measurement properties.

Travel has individual, societal and planetary health implications. We explored socioeconomic and gendered differences in travel behaviour in Africa, to develop an understanding of travel-related inequity. We conducted a mixed-methods systematic review (PROSPERO CRD42019124802). In 2019, we searched MEDLINE, TRID, SCOPUS, Web of Science, LILACS, SciELO, Global Health, Africa Index Medicus, CINAHL and MediCarib for studies examining travel behaviour by socioeconomic status and gender in Africa. We appraised study quality using Critical Appraisal Skills Programme checklists. We synthesised qualitative data using meta-ethnography, followed by a narrative synthesis of quantitative data, and integrated qualitative and quantitative strands using pattern matching principles. We retrieved 103 studies (20 qualitative, 24 mixed-methods, 59 quantitative). From the meta-ethnography, we observed that travel is: intertwined with social mobility; necessary to access resources; associated with cost and safety barriers; typified by long distances and slow modes; and dictated by gendered social expectations. We also observed that: motorised transport is needed in cities; walking is an unsafe, ‘captive’ mode; and urban and transport planning are uncoordinated. From these observations, we derived hypothesised patterns that were tested using the quantitative data, and found support for these overall. In lower socioeconomic individuals, travel inequity entailed reliance on walking and paratransit (informal public transport), being unable to afford travel, travelling less overall, and travelling long distances in hazardous conditions. In women and girls, travel inequity entailed reliance on walking and lack of access to private vehicles, risk of personal violence, societally-imposed travel constraints, and household duties shaping travel. Limitations included lack of analytical rigour in qualitative studies and a preponderance of cross-sectional quantitative studies (offering a static view of an evolving process). Overall, we found that travel inequity in Africa perpetuates socioeconomic and gendered disadvantage. Proposed solutions focus on improving the safety, efficiency and affordability of public transport and walking., Highlights • Utilised meta-ethnography and pattern-matching principles. • Revealed travel patterns differed by socioeconomic status and gender. • Travel inequity compounded disadvantage. • Females and poor people more likely to rely on walking. • Cost, safety and cultural factors were barriers to travel.

Physical inactivity is increasing in low- and middle-income countries (LMICs), where noncommunicable diseases (NCDs), urbanisation and sedentary living are rapidly growing in tandem. Increasing active living requires the participation of multiple sectors, yet it is unclear whether physical activity (PA)-relevant sectors in LMICs are prioritising PA. We investigated to what extent sectors that influence PA explicitly integrate it in their policies in an LMIC such as Cameroon. We systematically identified policy documents relevant to PA and NCD prevention in Cameroon; and using the Walt and Gilson policy triangle we described, analysed, and interpreted the policy contexts, contents, processes, and actors. We found 17 PA and NCD policy documents spanning from 1974 to 2019 across seven ministries. Thirteen (13/17) policies targeted infrastructure improvement, and four (4/17) targeted communication for behaviour change, all aiming to enhance leisure domain PA. Only the health sector explicitly acknowledged the role of PA in NCD prevention. Notably, no policy from the transport sector mentioned PA. Our findings highlight the need for intersectoral action to integrate PA into policies in all relevant sectors. These actions will need to encompass the breadth of PA domains, including transport, while emphasising the multiple health benefits of PA for the population.

Funder: National Institute for Health Research; Grant(s): GHR:16/137/34, Noncommunicable diseases contribute the greatest to global mortality. Unhealthy diet���a prominent risk factor���is intricately linked to urban built and food environments and requires intersectoral efforts to address. Framings of the noncommunicable disease problem and proposed solutions within global and African regional diet-related policy documents can reveal how amenable the policy landscape is for supporting intersectoral action for health in low-income to middle-income countries. This study applied a document analysis approach to undertake policy analysis on global and African regional policies related to noncommunicable disease and diet. A total of 62 global and 29 African regional policy documents were analysed. Three problem frames relating to noncommunicable disease and diet were identified at the global and regional level, namely evidence-based, development, and socioeconomic frames. Health promotion, intersectoral and multisectoral action, and evidence-based monitoring and assessment underpinned proposed interventions to improve education and awareness, support structural changes, and improve disease surveillance and monitoring. African policies insufficiently considered associations between food security and noncommunicable disease. In order to effectively address the noncommunicable disease burden, a paradigm shift from ���health for development��� to ���development for health��� is required across non-health sectors. Noncommunicable disease considerations should be included within African food security agendas, using malnutrition as a possible intermediary concept to motivate intersectoral action to improve access to nutritious food in African low-income to middle-income countries.

This article provides descriptive insights of the experiences of family caregivers of persons living with dementia during the COVID-19 pandemic. Data were generated as part of a qualitative cross-national project to explore the costs and consequences of providing unpaid dementia care. Participants in Jamaica, who were recruited using community gatekeepers, information booths at health fairs, conferences, and other outreach events, were contacted by telephone to discuss their experiences of the pandemic. When face-to-face in-depth interview data collection was suspended due to the pandemic, ethical approval was received to contact all research participants who were informal unpaid family caregivers, both those whose care recipients had died and those who were active caregivers ( N = 19). Participants in this study were the 10 active family caregivers ( n F = 8; aged 45+; 60% from high socio-economic status). Their updates and reflections during these calls were documented in fieldnotes and analyzed for key themes. Data showed that the pandemic has illustrated the direct costs, both financial and otherwise, that informal dementia carers bear in Jamaica. It also intensified pre-existing challenges faced by family carers. We provide recommendations for sustainable support for family carers.

Objectives: This study sought to identify coronavirus disease 2019 (COVID-19) risk communication materials distributed in Jamaica to mitigate the effects of the disease outbreak. It also sought to explore the effects of health risk communication on vulnerable groups in the context of the pandemic. Methods: A qualitative study was conducted, including a content analysis of health risk communications and in-depth interviews with 35 purposively selected elderly, physically disabled, persons with mental health disorders, representatives of government agencies, advocacy and service groups, and caregivers of the vulnerable. Axial coding was applied to data from the interviews, and all data were analyzed using the constant comparison technique. Results: Twelve of the 141 COVID-19 risk communication messages directly targeted the vulnerable. All participants were aware of the relevant risk communication and largely complied. Barriers to messaging awareness and compliance included inappropriate message medium for the deaf and blind, rural location, lack of Internet service or digital devices, limited technology skills, and limited connection to agencies that serve the vulnerable. Conclusion: The vulnerable are at increased risk in times of crisis. Accessibility of targeted information was inadequate for universal access to health information and support for vulnerable persons regardless of location and vulnerability.

Evidence from middle-income countries indicates high and increasing prevalence of dementia and need for services. However, there has been little investment in care, treatment or support for people living with dementia and their carers. The Strengthening Responses to Dementia in Developing Countries (STRiDE) project aims to build both research capacity and evidence on dementia care and services in Brazil, Indonesia, India, Jamaica, Kenya, Mexico and South Africa. This article presents the Theory of Change (ToC) approach we used to co-design our research project and to develop a strategic direction for dementia care, treatment and support, with stakeholders. ToC makes explicit the process underlying how a programme will achieve its impact. We developed ToCs in each country and across the STRiDE project with researchers, practitioners, people living with dementia, carers and policymakers at different levels of government. This involved (1) an initial ToC workshop with all project partners (43 participants); (2) ToC workshops in each STRiDE country (22–49 participants in each); (3) comparison between country-specific and overall project ToCs; (4) review of ToCs in light of WHO dementia guidelines and action plan and (5) a final review. Our experiences suggest ToC is an effective way to generate a shared vision for dementia care, treatment and support among diverse stakeholders. However, the project contribution should be clearly delineated and use additional strategies to ensure appropriate participation from people living with dementia and their carers in the ToC process.

Jamaica’s ageing population, high prevalence of non-communicable diseases (NCDs), and associated functional impairments suggest the need for a sustainable long-term care (LTC) system. This paper describes the current LTC system in Jamaica. A review of empirical and grey literature on LTC was supplemented with consultations and interviews and group discussions for knowledge exchange, impact and engagement events with stakeholders being conducted as part of a project on dementia care improvement. Four key findings emerged: (1) Jamaica’s LTC system depends substantially on informal care (both unpaid and paid); (2) there is a need for strategic coordination for LTC across the state, cross-ministerial, private, and volunteer sectors; (3) compulsory insurance and social protection schemes appear to exacerbate rather than narrow socioeconomic inequalities in LTC; and (4) there is a lack of systematic LTC data gathering and related information systems in both the private and public sector—for both institutional and community-based care. For LTC in Jamaica and the broader Caribbean region to be sustainable, more evidence-informed policies and practices that address inequalities in access to services, ability to pay for care, direct support from government, and the risk of needing LTC are needed.

Objectives: Sleep problems are associated with a host of psychiatric disorders and have been attributed to race disparities in health and wellness. Studies of sleep and mental health do not typically consider within-group differences among Blacks. Thus, our understanding of how the sleep-mental health relationship among Caribbean Blacks is limited. This study identified sleep profiles among Caribbean-born Blacks who reside in the United States.Design: Latent class analysis and data from the National Survey of American Life Re-interview study were used to identify and compare the associations between 'sleep quality classes,' sociodemographic factors, stress, and depression risk among Caribbean Blacks.Results: Two sleep quality classes were identified - 'good sleep quality' and 'poor sleep quality' - with each class demonstrating a complex pattern of sleep experiences, and illuminating the association between sleep and depression risk.Conclusions: Findings provide insight into the influence of sociodemographic factors and social stressors on the sleep experience of Caribbean Blacks and the importance of considering within-group differences to better understand risk and resilience among Caribbean Blacks living in the United States. Findings also highlight the importance of screening for sleep problems in an effort to reduce the burden of depression experienced by this population.

This methodological discussion invites critical reflection about the procedures used to analyze the contribution of qualitative and mixed methods research to nursing trials by mounting an argument that these should rest on multiple publications produced about a project, rather than a single article. We illustrate the value-added of this approach with findings from a qualitative, cross-case analysis of three critical case exemplars from nursing researchers that each used a qualitative approach with a mixed method phase. The holistic lens afforded by a case-based approach informs nursing inquiry by documenting that the critical case exemplars presented evidence of (a) a sustained commitment of resources and expertise for the qualitative methods that extended across more than one phase of the trial, (b) the impact of the qualitative methods on the trial or its aftermath, (c) deploying a theoretical or conceptual framework for a variety of purposes, and (d) integrating qualitative and quantitative data for purposes of extending explanatory power. Findings challenge the practice of linking purposes served by qualitative and mixed methods to a single trial phase.

Background More than half of deaths in low- and middle-income countries (LMICs) result from conditions that could be treated with emergency care - an integral component of universal health coverage (UHC) - through timely access to lifesaving interventions. Methods The World Health Organization (WHO) aims to extend UHC to a further 1 billion people by 2023, yet evidence supporting improved emergency care coverage is lacking. In this article, we explore four phases of a research prioritisation setting (RPS) exercise conducted by researchers and stakeholders from South Africa, Egypt, Nepal, Jamaica, Tanzania, Trinidad and Tobago, Tunisia, Colombia, Ethiopia, Iran, Jordan, Malaysia, South Korea and Phillipines, USA and UK as a key step in gathering evidence required by policy makers and practitioners for the strengthening of emergency care systems in limited-resource settings. Results The RPS proposed seven priority research questions addressing: identification of context-relevant emergency care indicators, barriers to effective emergency care; accuracy and impact of triage tools; potential quality improvement via registries; characteristics of people seeking emergency care; best practices for staff training and retention; and cost effectiveness of critical care – all within LMICs. Conclusions Convened by WHO and facilitated by the University of Sheffield, the Global Emergency Care Research Network project (GEM-CARN) brought together a coalition of 16 countries to identify research priorities for strengthening emergency care in LMICs. Our article further assesses the quality of the RPS exercise and reviews the current evidence supporting the identified priorities.

The STRiDE project sets out to support the development of effective dementia policy in middle-income countries (Brazil, India, Indonesia, Jamaica, Kenya, Mexico, and South Africa). As part of this it will generate new data about the prevalence of dementia for a subset of these countries. This study aims to identify the current estimates of dementia prevalence in these countries and where the gaps lie in the current literature. A systematic review was completed on 30th April 2019 across electronic databases, identifying dementia prevalence literature originating from any of the seven countries. Four hundred and twenty-nine records were identified following de-duplication; 28 studies met the inclusion criteria and were included in the systematic review. Pooled estimates of dementia prevalence ranged from 2% to 9% based on DSM-IV criteria; these figures were generally higher in studies using other diagnostic criteria (e.g. the 10/66 algorithm). Available prevalence data varied between countries. Only Brazil, Mexico and India had data derived from studies judged as having a low risk of bias. Irrespective of country, studies often were not explicit in detailing the representativeness of their sample, or whether there was non-response bias. Further transparent and externally valid dementia prevalence research is needed across the STRiDE countries.

Walking and cycling infrastructure and quality open spaces (‘active living infrastructure’) can influence levels of physical activity and related risks of non-communicable disease. Understanding the challenges to creating active living infrastructure could help support the creation of more physically active communities. A qualitative study with nine semi-structured interviews was conducted with ten expert stakeholders purposively sampled across the sectors of urban development, public health and civil society in Jamaica. Thematic analysis found that new active living infrastructure was challenging to provide because it did not fit with widely held views of ‘development’ which focused on road construction, driving and economics, not walking, cycling or nature. Public open spaces were lacking and the few good examples were expensive to maintain, deterring additional investment. Pedestrian infrastructure was poor quality and cycling infrastructure non-existent, making it dangerous for people to walk or cycle which particularly adversely affected people from deprived communities who may lack political voice. Greater collaboration between public health and urban planning, which appeared to be natural allies with shared interests, could help re-frame the multi-sectoral (including economic) benefits of active living infrastructure. Brokers may highlight problems associated with lack of active living infrastructure and also provide contextually relevant examples which go beyond generic international guidance.

BACKGROUNDIdeal cardiovascular health (ICH) is associated with greater longevity and reduced morbidity, but no research on ICH has been conducted in Jamaica. We estimated the prevalence of ICH in urban Jamaica and evaluated associations between ICH and community, household and individual socioeconomic status (SES).METHODSCross-sectional study using data from 360 men and 665 women, age ≥20 years in urban Jamaica. ICH was defined as having seven characteristics: current non-smoking, healthy diet, moderate physical activity, and normal body mass index, blood pressure, glucose, and cholesterol. Logistic regression, weighted for survey design, quantified association between the outcome (≥5 ICH characteristics [ICH-5]), and exposure variables (tertiles of community median land value [MLV], tertiles of household assets and educational attainment).RESULTSPrevalence of ICH (7 characteristics) was 0.51%, while prevalence of ICH-5 was 22.9% (male 24.5%, female 21.5%, p=0.447). In sex-specific multivariable models adjusted for age, education, and household assets, men in the lower tertiles of community MLV had lower odds of ICH-5 compared to men in the upper tertile (lowest tertile: OR 0.33, 95%CI 0.12-0.91, p=0.032; middle tertile: OR 0.46 (0.20-1.04) p=0.062). Women from communities in the lower and middle tertiles of MLV also had lower odds of ICH-5, but association was not statistically significant. Educational attainment was inversely associated with ICH-5 among men and positively associated among women. No significant association was seen for household assets.CONCLUSIONPrevalence of ICH is low in urban Jamaica. Living in poorer communities was associated with lower odds of ICH-5 among men. Higher education was associated with higher odds of ICH-5 among women but lowers odds among men.

Telomeres are the protective caps at the ends of eukaryotic chromosomes. Short telomere length is associated with morbidity and mortality among adults and may mark the biological impact of social experiences. Using archived dried blood spots from the Michigan Neonatal Biobank, this study examined markers of maternal social disadvantage (educational attainment, receipt of public assistance, marital status, and race/ethnicity) from linked birth certificates as predictors of telomere length at birth in a sample of 192 singleton neonates born to non-Hispanic black, non-Hispanic white, and Latina mothers aged 20-35 years. Consistent with two recent studies in newborns, but counter to the idea that maternal social disadvantage is associated with shorter offspring telomere length, we found that infants born to black mothers had longer telomeres than those born to white mothers (b = 0.12, SE = 0.06, p = .05). However, black/white differences in newborn telomere length varied by receipt of public assistance. Among newborns whose mothers received WIC and/or Medicaid, there were no significant black/white differences in telomere length (b = 0.09, SE = 0.08, p = .25). In contrast, among those whose mothers did not receive public assistance-just 6 out of 69 infants born to black mothers versus 41 out of 69 infants born to white mothers-we found that babies born to black mothers had longer telomere length than babies born to white mothers (b = 0.37, SE = 0.16, p = .03). The interaction between black race/ethnicity and receipt of public assistance did not reach the conventional threshold for statistical significance (b = -0.22, SE = 0.15, p = .13), suggesting that this finding may be due to chance. No other markers of maternal social disadvantage were related to infant telomere length. Although replication of these results in a larger sample with more infants born to black mothers with relatively high socioeconomic status is needed, this study offers preliminary support for the hypothesis that race/ethnic differences in newborn telomere length depend on social context.

This study compares the provision and receipt of kin support for Jamaican immigrants in the US and Jamaican nationals residing in Jamaica. Two datasets are utilized for the study. US data is from the National Survey of American Life (NSAL) which contains the first national probability sample of Caribbean immigrants in the USA. Data for Jamaican nationals comes from the Family Connections across Generations and Nations, a dataset associated with the NSAL. Findings indicate that both Jamaican immigrants and Jamaican nationals provide and receive substantial support from family members. Age and parental and marital status impact the amount of support given and received. In particular, there is a significant interaction between parental status, age, and receiving support that is consistent for both Jamaican immigrants in the US and Jamaican nationals. Findings are discussed in relation to previous research in this field.

Background Healthy environments need to be created that enable easy access to healthy and nutritious food. Complex and expanding urbanisation has had deleterious effects on the diet and health of city dwellers; yet urban planning offers a potential mechanism for public health strategies. To inform such policy efforts in the Caribbean, we conducted a cross-disciplinary study to understand historical and epidemiological transformations in Kingston, Jamaica. With this case study, we aimed to develop methods and conceptual tools for investigating the historical social, political and economic contexts that have shaped contemporary foodscapes and can inform future nutrition strategies. Methods Caribbean historians analysed principally online Jamaican newspaper archives to examine changes in food availability, affordability and consumption, and public discourses around eating, particularly fast food and other types of unhealthy food, from 1945 to present. Public health researchers undertook a scoping review to map available regional health survey databases for local nutrition and related health data, to examine major epidemiological trends in nutrition for the same time frame and assess its impact on non-communicable diseases. Geographical information scientists mapped the health and historical data to produce an interactive map of the evolution of Kingston’s foodscape. Results Preliminary historical findings include the increasing popularisation of commercial, more quickly prepared meals between the 1950s and 1970s; a national campaign to promote locally produced food crops in the diet to address food scarcity in the late 1970s; and the proliferation of United States fast food chains in Kingston in the 1980s. The health data review found thirteen relevant health or nutrition surveys on malnutrition including childhood stunting rates, nutrient deficiency and obesity rates. Few predate the 1980s and many only offer national (versus city level) data. Annual health and demographic reports pre- and post-independence in 1962 might be able to fill data gaps. For the geographical information systems map, we had to identify relevant historical address points, as well as identify and digitalise historical maps from 1945 onwards onto which data can be layered. Conclusion Structural approaches to public health require us to expand the scope of transdisciplinary research and build the methodological capacity to make ‘non-traditional’ connections. In this case study of the health history of a major Caribbean urban space, while not claiming causal relationships between historic and health trends, we suggest the important role that natural events, international and local policies, and advertising driven economies play in the production of ‘unhealthy’ foodscapes over time. This project was funded by the UK Medical Research Council – Arts and Humanities Research Council GCRF Global Public Health Partnership Award [Grant number: MR/R024324/1].

ObjectiveIdeal cardiovascular health (ICH) is associated with greater longevity and reduced morbidity, but no research on ICH has been conducted in Jamaica. We aimed to estimate the prevalence of ICH in urban Jamaica and to evaluate associations between ICH and community, household, and individual socioeconomic status (SES).DesignCross-sectional study.SettingUrban communities in Jamaica.Participants360 men and 665 women who were urban residents aged ≥20 years from a national survey, the Jamaica Health and Lifestyle Survey 2016–2017.ExposuresCommunity SES, using median land values (MLV); household SES, using number of household assets; and individual SES, using education level.Primary outcomeThe main outcome variable was ICH, defined as having five or more of seven ICH characteristics (ICH-5): current non-smoking, healthy diet, moderate physical activity, normal body mass index, normal blood pressure, normal glucose and normal cholesterol. Prevalence was estimated using weighted survey design and logistic regression models were used to evaluate associations.ResultsThe prevalence of overall ICH (seven characteristics) was 0.51%, while the prevalence of ICH-5 was 22.9% (male 24.5%, female 21.5%, p=0.447). In sex-specific multivariable models adjusted for age, education, and household assets, men in the lower tertiles of community MLV had lower odds of ICH-5 compared with men in the upper tertile (lowest tertile: OR 0.33, 95% CI 0.12 to 0.91, p=0.032; middle tertile: OR 0.46, 95% CI 0.20 to 1.04, p=0.062). Women from communities in the lower and middle tertiles of MLV also had lower odds of ICH-5, but the association was not statistically significant. Educational attainment was inversely associated with ICH-5 among men and positively associated among women.ConclusionLiving in poorer communities was associated with lower odds of ICH-5 among men in Jamaica. The association between education level and ICH-5 differed in men and women.

Objective: To identify the best practices of research staff that facilitate achieving enrollment and retention targets in biomedical cohort studies in Black Caribbean populations. Design and Methods: Eight focus group discussions (FGDs) were held with research stakeholders including research (i) nurses/ study supervisors, (ii) field staff/data collectors and (iii) rural and urban participants of the Third Jamaica Health and Lifestyle Survey (a national NCD risk factor survey with biospecimen collection) to capture qualitative data on experiences with recruitment, training, logistical issues in the field, retention challenges and potential solutions or strategies for strengthening future efforts. Results: Our findings suggest that ongoing training and supervision with clearly defined roles and responsibilities of the study staff enhanced the adeptness of field operations and attracted volunteers. Targeted community engagement and strong support in the field from the coordinating center increased the reach and efficiency of the data collectors. The need for gender appropriate approaches and socioeconomic balance to enhance equitable enrollment and participation in all aspects of the study was emphasized. Conclusion: Enrollment and retention in Jamaican studies is improved by creating and sustaining well-functioning research teams and applying community and gender appropriate approaches. These strategies may also enhance the recruitment of other Black populations in the Diaspora including the US and Caribbean into biomedical studies including cancer research.

This study compares the health conditions of domestic Caribbeans with those living in the United States to explore how national context and migration experiences might influence substance use (i.e., alcohol or drug) and other mental and physical health conditions. The study is based upon probability samples of non-institutionalized Caribbeans living in the United States (1621), Jamaica (1216) and Guyana (2068) 18 years of age and over. Employing descriptive statistics and multivariate analytic procedures, the results revealed that substance use and other physical health conditions and major depressive disorder and mania vary by national context, with higher rates among Caribbeans living in the United States. Context and generation status influenced health outcomes. Among first generation black Caribbeans, residing in the United States for a longer length of time is linked to poorer health outcomes. There were different socio-demographic correlates of health among at-home and abroad Caribbeans. The results of this study support the need for additional research to explain how national context, migratory experiences and generation status contribute to understanding substance use and mental disorders and physical health outcomes among Caribbean first generation and descendants within the United States, compared to those remaining in the Caribbean region.
