The objective of this study was to examine the association of ethnoracial background and immigrant status to cannabis use among students in Ontario, Canada. Data were derived from the Ontario Student Drug Use and Health Survey, a school-based, province-wide survey of students in Grades 7–12. The survey utilized a stratified two-stage cluster design. Analyses were based on a pooled subsample of 12,527 students in Grades 9–12 during the 2011 and 2013 survey cycles and included adjustments for the complex sample design. Results indicate that youth who were of South Asian or East/Southeast Asian background were at lower odds of cannabis use than those who were White, Black, or mixed-race backgrounds. Youth who were of mixed-race background (i.e., White and another group) were at higher odds of cannabis use than youth who were of White background. The association between ethnoracial background and cannabis use also varied for some foreign-born and native-born youth. These findings suggest that ethnoracial background should be an important consideration in investigations of cannabis use among foreign- relative to native-born youth. [ABSTRACT FROM PUBLISHER]

Background: Several studies have found a connection between attentional deficit hyperactivity disorder (ADHD) and criminal behaviour in clinical and prison samples of adults, but there is a lack of representative general population data on this.Aim: To test relationships between histories of ADHD and arrest. Our main research question was whether any such relationship is direct or best explained by co-occurring variables, especially indicators of social bonds.Method: Data were from a sample of 5,376 adults (18+) representative of the general population of Ontario, Canada. Logistic regression analysis was used to explore the relationship between self-reported arrest on criminal charges and ADHD as measured by the Adult Self Report Scale (ASRS-v1.1). Indicators of strong social bonds (post secondary education, household size) and weak bonds (drug use, antisocial behaviours, alcohol dependence) were also obtained at interview and included in the statistical models.Results: In a main effects model, screening positive for ADHD was twice as likely (OR 2.05 CI 1.30, 3.14) and past use of medications for ADHD three times as likely (OR 3.94 CI 2.46, 6.22) to be associated with ever having been arrested. These associations were no longer significant after controls for weak and strong social bonds were added to the models. In the best fitting statistical model, ever having been arrested was not associated with ADHD, but it was significantly associated with indicators of strong and weak social bonds.Conclusions: The observed connection between ADHD and criminality may be better understood through their shared relationships with indicators of poor social bonds. These include antisocial behaviour more generally, but also drug use and failure to progress to any form of tertiary education, including vocational training. Copyright © 2017 John Wiley & Sons, Ltd.

Background and aims Little research has examined the relationship between incentives used by gambling venues to attract customers and the experience of gambling-related harm. Organized and subsidized bus tours are a common example of such incentives. The aim of this study was to examine whether bus-tour patronage was associated with increased odds of problem gambling among older adults. This study also compared rates of bus-tour use by socio-demographic characteristics and gambling behaviours. Design Pearson's χ2 tests and Mann-Whitney U-tests were applied for bivariate analyses. Multivariate generalized mixed-effects regression modelling was used to examine the relationship between bus-tour patronage and problem gambling while controlling for possible confounding factors. Setting Seven gambling venues located in Central and Southwestern Ontario, Canada. Participants A total of 1978 gambling venue patrons over the age of 55 years. Measurements Problem gambling as indicated by the Problem Gambling Severity Index, bus-tour patronage in the 12 months prior to the survey, spending per gambling visit and past-month slot machine participation. Findings Regression analyses showed that bus-tour patronage was associated with higher odds of problem gambling [odds ratio (OR) = 1.71, confidence interval (CI) = 1.06, 2.76] after controlling for several demographic characteristics, type of gambling and gambling expenditures. Bivariate analyses showed past-year bus-tour patronage was associated with more frequent slot machine play (χ2 = 48.16, P < 0.001), more past-year gambling venue visits ( P < 0.001) and lower spending on gambling per casino visit ( P < 0.001). Compared with non-patrons, bus tour patrons were more likely to be female (χ2 = 21.92, P < 0.001), born outside Canada (χ2 = 113.18, P < 0.001), above the age of 75 (χ2 = 24.02, P < 0.001) and retired (χ2 = 16.60, P < 0.001). Conclusions When adjusting for potential confounders among older adults, using bus tours to access Canadian gambling venues is associated with increased risk of problem gambling. Bus-tour patrons are more likely to be female, born outside Canada and above the age of 75 years. [ABSTRACT FROM AUTHOR]

Background Production and distribution of prescription opioid analgesic drugs (POs) has increased immensely across the globe. Both medical (MPO) and non-medical (NMPO) use of opioid medication are associated with increased rates of morbidity and mortality, including possibly motor vehicle collisions. The current study examined data from a population-level survey to determine the impact of any PO, MPO, and NMPO use on collision risk. Methods Data were based on the 2010–2011 Centre for Addiction and Mental Health Monitor, a regionally stratified general-population telephone survey of adults ( N = 3428). Three binary logistic regressions of self-reported collision involvement in the previous 12 months were conducted, each consisting of: (1) measures of demographic characteristics, driving exposure, and binge drinking; and (2) one of three measures of PO use (any PO use, MPO use, or NMPO use). Results Any PO use and MPO use were associated with increased collision risk ( OR = 1.60, CI = 1.06, 2.40 and OR = 1.62, CI = 1.07, 2.45, respectively). The odds ratio for NMPO use did not reach statistical significance ( OR = 1.86, CI = 0.91, 3.77, p = 0.09). Conclusions These results suggested that doctor-prescribed PO use is associated with a 62% increase in collision risk. Although not a statistically significant finding, NMPO use may also be associated with increased collision risk. The magnitude of increased collision risk associated with PO use was comparable to that of driving after alcohol or cannabis use. [ABSTRACT FROM AUTHOR]

Background:Smoking behavior and smoking cessation are complex. Interpersonal factors such as childhood adversity are associated with smoking, especially in women. Identifying how and in whom these individual factors contribute to smoking behavior may support individualized smoking cessation strategies. Attachment insecurity (attachment avoidance and attachment anxiety) involves biological and psychological processes in close relationships and is associated with both childhood adversity, and in select populations, smoking. This study aims to identify an association between attachment insecurity and smoking in adults and to determine if attachment insecurity is a plausible mediator between childhood adversity and smoking. Methods:In a cross-sectional survey, 348 primary care patients reported childhood adversity, attachment insecurity and smoking status. Statistical analyses were performed using regression and PRODCLIN. Results:Sixty-one percent of participants had experienced childhood adversity and 20% were current smokers. In women, attachment anxiety was associated with both childhood adversity (p = .002) and current smoking (p = .04). The PRODCLIN test indicated that attachment anxiety may be a mediator between childhood adversity and current smoking in women (95%CI 0.003, 0.236). In men, current smoking was not associated with childhood adversity (p = .673) or attachment anxiety (p = .29). Attachment avoidance was not related to current smoking in men (p = .31) or in women (p = .16). Conclusions:In women but not in men, attachment anxiety is associated with current smoking and may mediate the relationship between childhood adversity and current smoking. Childhood adversity and attachment anxiety may be factors to consider in the design of cessation strategies for women. [ABSTRACT FROM AUTHOR]

As older adults continue to make up a greater proportion of the Canadian population, it becomes more important to understand the implications that their leisure activities have for their physical and mental health. Gambling, in particular, is a form of leisure that is becoming more widely available and has important implications for the mental health and financial well-being of older adults. This study examines a large sample (2103) of casino-going Ontarian adults over the age of 55 and identifies those features of their gambling participation that are associated with problem gambling. Logistic regression analysis is used to analyze the data. Focusing on types of gambling participated in and motivations for visiting the casino, this study finds that several forms of gambling and motivations to gamble are associated with greater risk of problem gambling. It also finds that some motivations are associated with lower risk of problem gambling. The findings of this study have implications related to gambling availability within an aging population.
