Adult attention-deficit hyperactivity disorder symptoms and psychological distress, hazardous drinking, and problem gambling: A population-based study.

Recognition of ADHD in the adult population is relatively recent. Epidemiological research examining the mental health impact of ADHD in adulthood is thus limited. The objective of this study was to examine whether adult ADHD symptoms are associated with psychological distress, hazardous drinking, and problem gambling, after controlling for traumatic brain injury and sociodemographic characteristics. We analyzed data from a population-based survey administered in 2015 and 2016 to adults aged 18 years and over in Ontario, Canada (N = 3,817). Logistic regression was used to construct unadjusted and multivariable models for each of the three focal relationships. In the unadjusted models, ADHD symptoms were significantly related to psychological distress (OR = 9.3; 95% CI:6.1, 14.0) and hazardous drinking (OR = 2.1; 95% CI: 1.3, 3.4), but not to problem gambling (OR = 1.5; 0.5, 4.3). After adjustment, ADHD symptoms were significantly related to psychological distress (OR = 7.1; 95% CI: 4.6, 11.1), but not hazardous drinking (OR = 1.4; 95% CI: 0.8, 2.5) or problem gambling (OR = 0.6; 95% CI: 0.2, 2.5). This study further highlights the importance of clinicians assessing for concomitant ADHD and psychological distress in adults.

Ethnicity, Immigration Status, And Driving Under The Influence Of Alcohol.

BACKGROUND: Understanding risk factors for driving under the influence of alcohol (DUIA) informs development of effective interventions. This study examined the association between ethnicity, immigration status, and DUIA, exploring psychological distress and hazardous drinking as additional contributors. METHOD: Data were derived from the 2003-2011 cycles of the Centre for Addiction and Mental Health (CAMH) Monitor of 16,101 adults from Ontario, Canada. Hierarchical binary logistic regression analysis assessed self-identified ethnicity and immigration status as predictors of DUIA, adjusting for sociodemographics and driving exposure (Model 1), psychological distress (Model 2), and hazardous drinking (Model 3). RESULTS: In Model 1, respondents born outside of Canada had reduced odds of engaging in DUIA compared to those born in Canada (AOR = 0.72, 95%CI = 0.56 - 0.92). Relative to those identifying as Canadian, the odds of DUIA were significantly reduced for those identifying as East Asian (AOR = 0.28, 95%CI = 0.13 - 0.61) and South Asian (AOR = 0.52, 95%CI = 0.27 - 0.98). In Model 3, individuals who reported psychological distress (AOR = 1.69, 95%CI = 1.33 - 2.16) and those who reported hazardous drinking (AOR = 6.28, 95%CI= 5.13 - 7.69) were more likely to DUIA. Those identifying as East Asian continued to have reduced odds of DUIA compared to those identifying as Canadian (AOR = 0.38, 95%CI = 0.17 - 0.85). CONCLUSION: Individuals born outside of Canada were less likely to engage in DUIA than individuals born in Canada. Drivers who self-identified as East Asian were less likely to DUIA than those who self-identified as Canadian. Understanding ethnic differences underlying divergent risks for DUIA will improve prevention initiatives and remedial measures programming.

Conduct disorder and attention-deficit/hyperactivity disorder as risk factors for prescription opioid use.

BACKGROUND: Existing studies of attention deficit/hyperactivity disorder (ADHD), conduct disorder (CD), and substance use or substance use disorders have produced mixed results, with some identifying a direct link between ADHD and general or disordered substance use and others suggesting that comorbid CD may explain this relationship. Insufficient research has addressed the issue, which is particularly relevant in the context of the opioid crisis. This study examined the association of probable ADHD and childhood CD with self-reported opioid use in a general-population sample. METHOD: The 2011-2013 cycles of the CAMH Monitor, a cross-sectional survey of adults (18+ years) from Ontario, Canada provided data from 6074 respondents. Binary logistic regressions were conducted of self-reported medical, non-medical, and any prescription opioid use in the previous 12 months, assessing demographic characteristics, perceived physical and mental health, and probable ADHD, childhood (before age 15 years) symptoms of CD, or their combination. RESULTS: Adjusting for potential covariates, probable ADHD alone was not associated with prescription opioid use. Childhood symptoms of CD significantly predicted non-medical use (OR = 2.10, 95% CI = 1.10, 4.03). ADHD and CD symptoms combined significantly predicted medical (OR = 3.27, 95% CI = 1.20, 8.91), non-medical (OR = 4.73, 95% CI = 1.05, 21.30), and any (OR = 3.02, 95% CI = 1.13, 8.11) prescription opioid use, although a low base rate of non-medical use may have negatively affected model fit. CONCLUSIONS: Previous findings relating ADHD to opioid use could be explained, in part, by the high rate of comorbidity between ADHD and CD. These data support prevention and treatment programs targeting individuals with comorbid ADHD and CD symptoms.

Assessing the impact of the 2015 introduction of increased penalties and enhanced public awareness and enforcement activities on texting while driving among adults in Ontario, Canada.

Objective: Texting while driving (TWD) is considered a particularly hazardous form of distracted driving. It is highly prevalent among young drivers, but fewer studies of TWD among adult drivers exist and these prevalence rates may approach those of younger drivers. The effectiveness of measures to prevent distracted driving, and TWD specifically, is unclear. On September 1, 2015, Ontario introduced increased penalties for distracted driving accompanied by public education programs to increase public awareness of the new regulations. Provincial police also introduced enhanced enforcement efforts. The current study examined self-reported TWD in a representative sample of Ontario adults before and after introduction of the new legislation and the enhanced public education and enforcement efforts.Methods: Data were based on telephone interviews with 1,846 respondents who reported having driven in the past year. Data were derived from the 2015-2016 cycles of the Centre for Addiction and Mental Health (CAMH) Monitor, an ongoing cross-sectional telephone survey of adults aged 18+ years in Ontario, Canada. A binary logistic regression analysis of TWD in the previous 30 days was conducted, adjusting for demographic characteristics (sex, age), driving exposure, and introduction of the legislation (before versus after).Results: The proportion of the sample reporting TWD declined significantly from 37.6% before the law was introduced to 24.2% after the law was introduced. The impact appeared to be most pronounced among drivers who reported TWD more frequently. Adjusted odds of TWD declined 42% following introduction of the legislation and associated enhanced public education and enforcement.Conclusions: These results identify a decrease in TWD following the introduction of enhanced penalties with corresponding public education and enforcement efforts, adding to the existing evaluative evidence base to inform transportation safety policy. These results also support the need to examine TWD and its determinants among all age groups.

Moderate to severe gambling problems and traumatic brain injury: A population-based study.

Traumatic brain injury (TBI) is a common injury characterized by a change in brain function after an external blow to the head and is associated with substance abuse, psychological distress, risk-taking, and impulsivity. Convenience and clinical samples have also linked TBI to problem gambling, but have not ruled out confounding variables such as hazardous drinking and psychological distress. This study examines the relationship between TBI and moderate to severe problem gambling in a general population probability sample controlling for hazardous drinking and psychological distress. The data were obtained from a 2015-2016 cross-sectional general population telephone survey of adults ages 18+from Ontario, Canada (N = 3809). Logistic regression was used to estimate the association as adjusted odds ratios (AOR). Moderate to severe problem gambling was independently associated with a history of TBI after adjusting for potential confounders (AOR: 2.80), and had a statistically significant relationship with psychological distress (AOR = 2.74), hazardous drinking (AOR = 2.69), and lower educational levels (AOR = 0.37). This study provides further data to suggest a link between TBI and moderate to severe problem gambling; however, more research is needed to determine if there is a causal relationship or the potential implications for prevention and treatment.

The relationship between motor vehicle collisions and cigarette smoking in Ontario: Analysis of CAMH survey data from 2002 to 2016.

Research has shown that tobacco users have an increased risk of collisions compared to nonsmokers. Studies from 1967 through 2013 documented a crude relative risk of collision involvement of about 1.5 among smokers compared to nonsmokers. In January 2009, in response to concerns about the health risks associated with potentially high concentrations of secondhand smoke resulting from smoking in vehicles, the provincial government in Ontario, Canada, introduced legislation restricting smoking in vehicles where children and adolescents are present. We examined the association between reported smoking and involvement in a motor vehicle collision in a large representative sample of adult drivers in Ontario, Canada, from 2002 and 2016, with particular focus on 2002-2008 and 2010-2016, periods before and after the legislation. Data are based on the Centre for Addiction and Mental Health (CAMH) Monitor. Among licensed drivers, prevalence of self-reported collision involvement within the past year for 2002-2008 was 9.39% among those who currently smoked compared to 7.08% of nonsmokers. Following implementation of the legislation, for 2010-2016, the prevalence of collisions for smokers was 7.01% and for nonsmokers was 6.02%. The overall difference for both smokers and nonsmokers between the two time periods was statistically significant; however, the difference between the two groups for the pre-legislation period was significant even after adjusting for potential confounders, while post legislation the difference was not significant. Prior to the legislation, the prevalence of collision was higher among smokers than nonsmokers; following the introduction of the legislation the prevalence was similar for the two groups.

Debt stress, psychological distress and overall health among adults in Ontario.

The objective of this study was to examine debt stress and its association with psychological distress and overall health. Data were derived from the 2014-2016 annual cycles of a cross-sectional telephone survey of the general population of adults 18 years of age and older within the province of Ontario, Canada. The present analyses focused on a pooled sample of 8045 adults. Results indicated that a large proportion of the sample reported experiencing debt-related stress. Those who were female, separated or divorced, and from lower income households were at higher odds of greater debt stress relative to no debt stress. Debt stress was significantly associated with psychological distress, as well as self-rated overall mental health and general health. Adults who reported greater debt stress were at higher odds of moderate to serious psychological distress, poor to fair self-rated mental health, and poor to fair self-rated general health compared to those with lower levels of debt stress. The association between debt stress and health did not vary by age, gender, employment, education, or income. The findings suggest that the stress surrounding debt is an important factor in the association between debt and health, the association is robust across various sociodemographic characteristics, and that further research is needed to better understand the nature of debt stress and its impact on health.

Traumatic brain injury and hazardous/harmful drinking: Concurrent and single associations with poor mental health and roadway aggression.

This study describes the association among lifetime traumatic brain injury (TBI) and past year hazardous/harmful drinking, as well as their unique and synergistic effects, on mental health problems and roadway aggression among Canadian adults. A cross-sectional sample of 6074 Ontario adults aged 18 years or older were surveyed between 2011 and 2013. TBI was defined as trauma to the head resulting in loss of consciousness or overnight hospitalization. Past year hazardous/harmful drinking was assessed using the Alcohol Use Disorders Identification Test. An estimated 13.1% (95%CI:12.0,14.2) adults reported a prior TBI (no hazardous/harmful drinking), 2.7% (95%CI:2.2,3.3) reported a prior TBI while concurrently screening positive for past year hazardous/harmful drinking and 9.8% (95%CI:8.9,10.9) screened positive for hazardous/harmful drinking (no TBI). Men had significantly higher odds of exhibiting all three conditions compared to women, especially for the concurrent class. Younger adults had significantly greater odds of hazardous/harmful drinking, or the concurrent class compared to adults 55 years and older. Adults in any of the three conditions had greater odds for mental health problems and roadway aggression. Concordance of both conditions corresponded to a greater than additive effect and greater odds of mild roadway aggression, than either condition alone. Results show that singly and jointly, these conditions are associated with adverse health and behavioral impediments.

Driving under the influence of prescription opioids: Self-reported prevalence and association with collision risk in a large Canadian jurisdiction.

BACKGROUND: Motor vehicle collisions are an important contributor to prescription opioid use-related morbidity and mortality. The purpose of the current study was to estimate the prevalence of driving under the influence of prescription opioids (DUIPO) in Ontario, Canada, and to measure the association between this behaviour and the risk of a motor vehicle collision. METHODS: Data were based on telephone interviews with 7857 respondents who reported having driven in the past year. Data were derived from the 2011-2016 cycles of the CAMH Monitor, an ongoing cross-sectional representative survey of adults aged 18 years and older. A binary logistic regression analysis of collision involvement in the previous 12 months was conducted and included demographic characteristics (sex, age, marital status, education, income, region), driving exposure, poor mental health, non-medical use of prescription opioids, and driving after use of alcohol. RESULTS: The prevalence of past-year DUIPO was 3.1%. Controlling for demographic characteristics, driving exposure, and other risk factors, self-reported DUIPO significantly increased the odds of a collision (AdjOR = 1.97; 95% CI 1.08, 3.60; p = 0.026). CONCLUSION: Based on these findings, DUIPO is a notable road safety issue. Research focused on better understanding the impact of prescription opioids on driver behaviour, reducing the prevalence of DUIPO, and improving drug-impaired driving policy and interventions should be prioritized in public health strategies.

Associations between self-reported lifetime history of traumatic brain injuries and current disability assessment in a population sample of Canadian adults.

OBJECTIVE: This study describes the association between history of lifetime traumatic brain injury (TBI) and current disabling functional restrictions among Ontario adults. SETTING AND DESIGN: A two-stage rolling cross-sectional sample of 6,048 adults aged 18 to 93 were interviewed by computer assisted telephone interviewing between 2011-2013 regarding their mental health and substance use in Ontario, Canada. TBI criteria were defined by loss of consciousness for minimum five minutes or at least one overnight hospitalization. Dimensions of functionality restrictions in the last 30 days were measured with the WHO Disability Assessment Schedule (WHODAS). RESULTS: The estimated mean for global disability in this sample of Ontario adults was 2.75 (SD = 5.4, range 0-40). The estimated means of global disability for individuals who reported a history of lifetime TBI was 4.16 (SD = 7.12) and compared with 2.46 (SD = 4.98) for individuals who never had a TBI (p < 0.001). Adults with a history of lifetime TBI had greater odds of global and item disability including restricted cognition, decreased self-care, difficulties with social relationships, fewer life activities and reduced participation in society compared to adults without a history of TBI (p < 0.001), even after adjusting for values of age, sex, marital status, household income and education. CONCLUSION: The co-occurrence of history of lifetime TBI with self-reported disability within the past 30 days provide evidence that careful consideration, planning and understanding of short and long term health needs of TBI survivors are critical.

Is there a link between motor vehicle collisions and being a cigarette smoker in Canada? Analysis of survey data from Ontario from 2002 to 2014.

OBJECTIVE: Although most research on drugs and driving has focused on the use of alcohol and cannabis, research that has been conducted on cigarette smoking and collisions has found that smokers have an increased collision involvement. Studies dating from 1967 through 2013 have shown a crude relative risk of about 1.5 among smokers compared to nonsmokers. In Canada, the association between smoking and collisions has not been recently investigated. Studies that have examined the association between smoking and collisions often did not control for all confounding factors, such as alcohol use and driving exposure, which have been associated with increased collision rates. Additionally, a number of these studies were examined in countries and at times when prevalence of smoking was much higher than is currently the case in Canada. The purpose of this research is to examine the association between self-reported current smoking and past-year collision involvement, controlling for confounding factors, in a large representative sample of adult drivers in Ontario, Canada, from 2002 and 2014. METHOD: Data are based on the Centre for Addiction and Mental Health (CAMH) Monitor, an ongoing, rolling telephone survey of Ontario adults that provides epidemiological surveillance of indicators related to alcohol, tobacco, and other drug use, as well as physical and mental health. The survey uses random-digit-dialing methods via Computer-Assisted Telephone Interview, with response rates over 50%. RESULTS: Prevalence of self-reported collision involvement within the past year for 2002-2014 was 8.6% among those who currently smoke compared to 6.5% of nonsmokers. Logistic regression analysis, controlling for the potential confounding effects of sociodemographics, driving exposure measures, drinking frequency, and hazardous alcohol use, found that the overall odds for collision involvement in the preceding year among current smokers for 2002-2014 was 1.27 (95% confidence interval [CI], 1.06-1.53) times that of nonsmokers. CONCLUSIONS: These findings indicate that despite a substantial reduction in overall prevalence of smoking in Canada, smokers still have a significantly increased odds of collision involvement, even when controlling for alcohol and exposure. Additionally, the results are consistent with the increased odds/risks of motor vehicle collisions found in other countries.

Associations between a history of traumatic brain injuries and conduct disorder during youth in a population sample of Canadian adults.

This study describes the association between history of traumatic brain injury (TBI) and childhood symptoms of conduct disorder (CD). Data were based on telephone interviews with 6048 respondents derived from the 2011-2013 cycles of a representative cross-sectional survey of adults aged 18+ years in Ontario, Canada. TBI was defined as loss of consciousness for at least 5min or overnight hospitalization due to injury symptoms. Symptoms of CD before 15 years of age were assessed using five items based on the DSM-IV. Adults who reported a history of TBI reported odds 3 times higher for possible CD before 15 years of age. Odds remained significant even when age, sex, marital status, income, and education were statistically controlled. The nature of this data precludes determining if TBI occurred before or following CD symptoms. Nonetheless, the co-occurrence of a history of TBI with symptoms of CD supports the recommendation that practitioners be vigilant in assessing the history of both CD and TBI when diagnosing and treating one of these conditions. These findings do not exclude the possibility that TBI during childhood or youth may be interfering with brain development and could co-occur with conduct behaviors in both the short and long term.

Therapeutic use of cannabis: Prevalence and characteristics among adults in Ontario, Canada.

OBJECTIVE: To investigate the prevalence of therapeutic cannabis use within a general population sample of adults and to describe various characteristics associated with use. METHODS: Data were derived from the 2013 and 2014 CAMH Monitor Survey of adults in Ontario, Canada. This repeated cross-sectional survey employed a regionally stratified design and utilized computer-assisted telephone interviewing. Analyses were based on 401 respondents who reported using cannabis. RESULTS: The data indicated that 28.8% of those who used cannabis in the past year self-reported using cannabis for therapeutic purposes. Of therapeutic users, 15.2% reported having medical approval to use cannabis for therapeutic purposes. Cannabis use for therapeutic purposes was associated with more frequent use of cannabis, a moderate to high risk of problematic cannabis use, and a greater likelihood of using prescription opioids for medical purposes. There was little difference in cannabis use for therapeutic purposes according to sex, age, and marital status after adjusting for opioid use and problematic cannabis use. CONCLUSION: Findings suggest some potential negative consequences of cannabis use for therapeutic purposes; however, further research is needed to better understand the range and patterns of use and their corresponding vulnerabilities.

Past year cannabis use and problematic cannabis use among adults by ethnicity in Ontario.

BACKGROUND: Rates of cannabis use differ around the world; in Ontario, the rate of use has been stable since about 2005. Understanding which population groups are at greater risk for problematic cannabis use can help reduce long-term health effects and service expenses. The aim of this study was to explore differences in cannabis use among Canadian adults of different ethnic origins living in Ontario. METHODS: Data are based on telephone interviews with 11,560 respondents and are derived from multiple cycles (2005-2011) of the Centre for Addiction and Mental Health's (CAMH) Monitor survey, an ongoing cross-sectional survey of adults in Ontario, Canada, aged 18 years and older. Data were analyzed using bivariate cross-tabulations and logistic regression. Problematic cannabis use was determined with a score of 8+ on the ASSIST-CIS to identify moderate/high problematic users. RESULTS: Lifetime, past year and problematic cannabis use (in the past 3 months) occurs among all ethnic groups: Canadian, East Asian, South East Asian, South Asian, Caribbean, African, East European, South European, North European, and Central West European. When compared to the Canadian group the odds of past year cannabis use was significantly lower for East Asians and South Asians, but higher for the Caribbean group. Significantly higher odds of problematic cannabis use were found for Caribbeans and Northern Europeans compared to Canadians. CONCLUSIONS: These results of this study provide an important basis for considering the possible impact of the impending legalization of cannabis in Canada among different ethnic groups.

Roadway Aggression Among Drivers and Passengers With or Without a History of Traumatic Brain Injury.

OBJECTIVE: This study examined the association between roadway aggression and traumatic brain injury (TBI) among drivers and passengers who reside in the province of Ontario, Canada. METHODS: Data were based on a 3-year cumulated cross-sectional sample of 6,048 adults aged 18 years and older who were surveyed by telephone. The outcome in this study was road rage in the form of verbal/gestural or physical aggression toward other road users and/or their vehicle. RESULTS: Driving status, history of TBI, age, gender, education, and the interaction between history of TBI and education significantly predicted roadway aggression. Odds ratios (ORs) for roadway aggression were significantly higher among drivers ( OR= 2.65) compared to passengers, between 2 and 4.5 times higher among individuals aged 18-64 years old compared to those older than 65 years, higher among adults with TBI (OR = 2.05) than without, and men (OR = 1.54) than women. Among respondents with lowest, but not highest, levels of education, roadway aggression was predicted by a history of TBI. CONCLUSION: This is the first population-based study to compare rates of roadway aggression between drivers and passengers with and without TBI. Research to understand these differences will be important for roadway aggression prevention efforts and policy.

Comparing Medical and Recreational Cannabis Users on Socio-Demographic, Substance and Medication Use, and Health and Disability Characteristics.

BACKGROUND: While recreational cannabis use is common, medical cannabis programs have proliferated across North America, including a federal program in Canada. Few comparisons of medical and recreational cannabis users (RCUs) exist; this study compared these groups on key characteristics. METHODS: Data came from a community-recruited sample of formally approved medical cannabis users (MCUs; n = 53), and a sub-sample of recreational cannabis users (RCUs; n = 169) from a representative adult survey in Ontario (Canada). Samples were telephone-surveyed on identical measures, including select socio-demographic, substance and medication use, and health and disability measures. Based on initial bivariate comparisons, multivariate logistical regression with a progressive adjustment approach was performed to assess independent predictors of group status. RESULTS: In bivariate analyses, older age, lower household income, lower alcohol use, higher cocaine, prescription opioid, depression and anxiety medication use, and lower health and disability status were significantly associated with medical cannabis use. In the multivariate analysis, final model, household income, alcohol use, and disability levels were associated with medical cannabis use. Conclusions/Scientific Significance: Compared to RCUs, medical users appear to be mainly characterized by factors negatively influencing their overall health status. Future studies should investigate the actual impact and net benefits of medical cannabis use on these health problems.

Street racing among the Ontario adult population: Prevalence and association with collision risk.

BACKGROUND: Street racing has been identified as a significant public health concern, yet, little is known about the prevalence of this behaviour and its impact on collision risk. The current study was designed to address this dearth of knowledge by estimating the prevalence of street racing among the Ontario, Canada adult population, and examining its association to collision risk, controlling for demographics and other risk factors. METHODS: Data were based on telephone interviews with 11,263 respondents derived from the 2009-2014 cycles of the CAMH Monitor, an ongoing cross-sectional survey of adults aged 18+ years. A hierarchical-entry binary logistic regression analysis of collision involvement in the previous 12 months was conducted and included measures of street racing, demographic characteristics (sex, age, marital status, education, income, region), driving exposure, and driving after use of alcohol and use of cannabis. RESULTS: The prevalence of street racing was 0.9%. Based on univariate analyses, street racing was more prevalent among males (1.30%; p<.01) and those aged 18-25 years (2.61%; p<.001). Controlling for demographic characteristics, driving exposure, and driving after use of alcohol and use of cannabis, self-reported street racing significantly increased the odds of a crash (OR=5.23, p<.001). DISCUSSION: A small but significant percentage of adult drivers in Ontario reported engaging in street racing. Even after adjusting for demographics, driving exposure, and driving after use of alcohol and use of cannabis, street racers faced more than a five-fold increase in the odds of a crash. Program and policy options must be considered to target this contingent.

Religion, Alcohol Use and Risk Drinking Among Canadian Adults Living in Ontario.

This research examines (1) the association between risk drinking and religious affiliation and (2) differences between religions for risk drinking among adults living in Ontario, Canada, for Christians, Buddhists, Sikhs, Muslims, Hindus, Jews, other religious groups and the non-religious. Data are based on telephone interviews with 16,596 respondents and are derived from multiple cycles (2005-2011) of the Centre for Addiction and Mental Health's (CAMH) Monitor survey, an ongoing cross-sectional survey of adults in Ontario, Canada, aged 18 years and older. Data were analysed using bivariate cross-tabulations, Mann-Whitney U nonparametric test and logistic regression. Alcohol use and risk drinking occur among members of all religious groups; however, the rate of drinking ranges widely. Risk drinking is significantly associated with religion. When compared to the No religion/Atheist group, several religious groups (Baptist, Christian, Hindu, Jehovah's Witness, Jewish, Muslim/Islam, Non-denominational, Pentecostal, Sikh and Other religion) in our sample have significantly lower odds of risk drinking. Risk drinkers also attended significantly fewer services among several religions. Results suggest that there are differences in the risk drinking rates among Canadian adults, living in Ontario, by religion. It appears that religious traditions of prohibition and abstention do hold sway among Canadian adults for some religious groups.

Problem Gambling in a Sample of Older Adult Casino Gamblers.

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.

Substance Use, Health, and Functioning Characteristics of Medical Marijuana Program Participants Compared to the General Adult Population in Ontario (Canada).

Existent profiles of Medical Marijuana Program (MMP) participants indicate common and co-morbid chronic diseases, yet evidence on disability or functioning as well as comparisons with general populations are largely lacking. This study compared health, substance use, and functioning status among formally approved MMP participants with the general adult population in Ontario (Canada). A community-recruited sample (n = 53) of MMP participants was compared to a sub-sample (n = 510) of the representative Centre for Addiction and Mental Health (CAMH) Monitor (2015 cycle) survey of Ontario general population adults (ages 18+) based on identical telephone-based interviews regarding substance use, health, and functioning measures. Means and standard deviations for all indicators were computed by sex, controlled for age and education, and compared by regression techniques. MMP participants were more likely to be male, younger, and less socio-economically integrated; they indicated more common psychoactive substance (e.g., tobacco, daily cannabis) and psychotropic medication use, as well as overall worse physical and mental health and functioning status. Marked differences between MMP participants and general population adults were observed. MMPs appear to attract individuals with complex chronic health problems; however, little is known about the impact of MMP participation on these.
