Willingness of population health survey participants to provide personal health information and biological samples.

Background: Biological sample collection and data linkage can expand the utility of population health surveys. The present study investigates factors associated with population health survey respondents' willingness to provide biological samples and personal health information.

Methods: Using data from the 2019 Centre for Addiction and Mental Health (CAMH) Monitor survey (n = 2,827), we examined participants' willingness to provide blood samples, saliva samples, probabilistic linkage, and direct linkage with personal health information.

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.

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.

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.

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.

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.

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

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.

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.

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).

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.

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.

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.

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.

The association between traumatic brain injury and ADHD in a Canadian adult sample.

Objective: This study describes the association between lifetime traumatic brain injury (TBI) and attention deficit and hyperactivity disorder (ADHD) among Canadian adults.

Method: A cross-sectional sample of 3993 Ontario adults aged 18 or older were surveyed by Computer Assisted Telephone Interviewing (CATI) throughout 2011 and 2012 as part of the CAMH Monitor, a rolling survey assessing the health, mental health and substance use of Ontario adults. TBI was defined as trauma to the head that resulted in loss of consciousness for at least five minutes or overnight hospitalization.

Gender Differences in Alcohol Use and Risk Drinking in Ontario Ethnic Groups.
