RESUMO

BACKGROUND: The effect of cannabis legalization in Canada (in October 2018) on the prevalence of injured drivers testing positive for tetrahydrocannabinol (THC) is unclear. METHODS: We studied drivers treated after a motor vehicle collision in four British Columbia trauma centers, with data from January 2013 through March 2020. We included moderately injured drivers (those whose condition warranted blood tests as part of clinical assessment) for whom excess blood remained after clinical testing was complete. Blood was analyzed at the provincial toxicology center. The primary outcomes were a THC level greater than 0, a THC level of at least 2 ng per milliliter (Canadian legal limit), and a THC level of at least 5 ng per milliliter. The secondary outcomes were a THC level of at least 2.5 ng per milliliter plus a blood alcohol level of at least 0.05%; a blood alcohol level greater than 0; and a blood alcohol level of at least 0.08%. We calculated the prevalence of all outcomes before and after legalization. We obtained adjusted prevalence ratios using log-binomial regression to model the association between substance prevalence and legalization after adjustment for relevant covariates. RESULTS: During the study period, 4339 drivers (3550 before legalization and 789 after legalization) met the inclusion criteria. Before legalization, a THC level greater than 0 was detected in 9.2% of drivers, a THC level of at least 2 ng per milliliter in 3.8%, and a THC level of at least 5 ng per milliliter in 1.1%. After legalization, the values were 17.9%, 8.6%, and 3.5%, respectively. After legalization, there was an increased prevalence of drivers with a THC level greater than 0 (adjusted prevalence ratio, 1.33; 95% confidence interval [CI], 1.05 to 1.68), a THC level of at least 2 ng per milliliter (adjusted prevalence ratio, 2.29; 95% CI, 1.52 to 3.45), and a THC level of at least 5 ng per milliliter (adjusted prevalence ratio, 2.05; 95% CI, 1.00 to 4.18). The largest increases in a THC level of at least 2 ng per milliliter were among drivers 50 years of age or older (adjusted prevalence ratio, 5.18; 95% CI, 2.49 to 10.78) and among male drivers (adjusted prevalence ratio, 2.44; 95% CI, 1.60 to 3.74). There were no significant changes in the prevalence of drivers testing positive for alcohol. CONCLUSIONS: After cannabis legalization, the prevalence of moderately injured drivers with a THC level of at least 2 ng per milliliter in participating British Columbia trauma centers more than doubled. The increase was largest among older drivers and male drivers. (Funded by the Canadian Institutes of Health Research.).

RESUMO

Driving under the influence of cannabis (DUIC) is detrimental to road safety. Risk perception is a strong determinant of DUIC behaviour, yet little is known about the factors influencing DUIC risk perception in the general population. The objective of this study was to identify factors associated with risk perceptions of motor vehicle collision and legal consequences due to DUIC and examine whether these perceptions were associated with DUIC behaviour. Data were derived from the 2017 CAMH Monitor, a cross-sectional telephone survey of adults aged 18+ years in Ontario, Canada (n = 1813). Multivariable logistic regression analyses were performed. Approximately 90% of adults overall agreed that DUIC increases motor vehicle collision risk compared to 55% of those reporting past-year DUIC. Being male, less educated, and using cannabis at least monthly were associated with disagreeing that DUIC increases motor vehicle collision risk. Being male, young, and using cannabis at least monthly were associated with agreeing that DUIC is safer than driving under the influence of alcohol (DUIA). Being male and using cannabis less than monthly were associated with agreeing that the chances of getting caught for DUIC are higher than DUIA. Safety but not legal risk perceptions were associated with DUIC behaviour among cannabis-using drivers. Cannabis legalization provides a timely opportunity for DUIC prevention strategies. This study suggests that policymakers should target male cannabis users and highlight the safety risks of DUIC. Further research is needed to assess the effectiveness of prevention measures and the impact of cannabis legalization on DUIC perceptions and behaviour.

RESUMO

OBJECTIVE: The objective of the current research was to examine the association between time spent on social media and serious psychological distress between 2013 and 2017, a period when the rates of both were trending upward. METHODS: The current study analyzed population-based data from 3 waves of the Ontario Student Drug Use and Health Survey (N = 15,398). Multivariate logistic regression models were used to examine the association between time spent on social media and serious psychological distress controlling for theoretically relevant covariates. Interactions were tested to assess whether the association changed over time. RESULTS: The prevalence of serious psychological distress increased from 10.9% in 2013 to 16.8% in 2017 concomitantly with substantial increases in social media usage, especially at the highest levels. In the multivariate context, we found a significant interaction between social media use and the survey year which indicates that the association between time spent on social media and psychological distress has decreased from 2013 to 2017. CONCLUSION: Although both social media use and psychological distress increased between 2013 and 2017, the interaction between these variables indicates that the strength of this association has decreased over time. This finding suggests that the higher rate of heavy social media use in 2017 compared to 2013 is not actually associated with the higher rate of serious psychological distress during the same time period. From a diffusion of innovation perspective, it is possible that more recent adopters of social media may be less prone to psychological distress. More research is needed to understand the complex and evolving association between social media use and psychological distress. Researchers attempting to isolate the factors associated with the recent increases in psychological distress could benefit from broadening their investigation to factors beyond time spent on social media.

RESUMO

As many jurisdictions consider relaxing cannabis legislation and usage is increasing in North America and other parts of the world, there is a need to explore the possible genetic differences underlying the subjective effects of cannabis. This pilot study investigated specific genetic variations within the cannabinoid receptor 1 (CNR1) gene for association with the subjective effects of smoked cannabis. Data were obtained from a double-blinded, placebo-controlled clinical trial studying the impact of cannabis intoxication on driving performance. Participants randomized to the active cannabis group who consented to secondary genetic analysis (n = 52) were genotyped at the CNR1 rs1049353 and rs2023239 polymorphic areas. Maximum value and area under the curve (AUC) analyses were performed on subjective measures data. Analysis of subjective effects by genotype uncovered a global trend towards greater subjective effects for rs1049353 T-allele- and rs2023239 C-allele-carrying subjects. However, significant differences attributed to allelic identity were only documented for a subset of subjective effects. Our findings suggest that rs1049353 and rs2023239 minor allele carriers experience augmented subjective effects during acute cannabis intoxication.

RESUMO

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.

RESUMO

OBJECTIVE: Stigma has been identified as a complex and problematic issue. It acts as a major barrier to accessing care and can exacerbate the experience of a health condition, particularly for clients with mental illness and substance use issues. Scales designed to assess stigmatising attitudes towards those with mental illness and substance use problems among health care providers are necessary to evaluate programs designed to reduce that stigma. The goal of this study was to evaluate the internal reliability and external validity of the Opening Minds Survey for Health Care Providers (OMS-HC). METHODS: The current study examined the use of the OMS-HC in assessing stigma held by Community Health Centre (CHC) staff towards clients with mental and/or substance use problems. Participants represented staff from 6 CHCs in the Greater Toronto Area ( n = 190). RESULTS: The OMS-HC was found to have acceptable internal reliability for the 15-item version of the scale (α = 0.766) and mixed reliability for its subscales (α = 0.792-0.673). Confirmatory factor analysis showed good absolute (root mean square error of approximation = 0.013) and relative fit (Tucker-Lewis index = 0.996) for the current data. The OMS-HC was also shown to correlate with a series of scales commonly used in stigma research. CONCLUSIONS: After testing for internal validity and comparing the OMS-HC to other commonly used scales for assessing stigma and attitudes concerning recovery, the scale was found to be appropriate for the CHC setting and may be advantageous over the use of multiple scales.

RESUMO

BACKGROUND: Harmful alcohol use is associated with disease and mortality. Identifying new determinants of harmful drinking may aid the 16.3 million adults who have alcohol use disorders. Childhood adversity is associated with alcohol use, but is not amenable to change. Attachment insecurity (anxiety and avoidance) may be associated with alcohol use and may be a target for modification or used to personalize interventions. OBJECTIVES: This study aims to (a) identify the association between attachment insecurity and harmful drinking, (b) determine if attachment insecurity may mediate between childhood adversity and harmful drinking, and (c) test sex as a moderator between attachment insecurity and harmful drinking in the mediation relationship. METHODS: Adult primary care patients (N = 348, 60% women) completed a cross-sectional survey study using validated measures in 2012. Statistical analyses were performed using Hayes's PROCESS macro in SPSS. RESULTS: Childhood adversity was reported by 61% of the cohort and 18% endorsed harmful drinking. Attachment anxiety was associated with harmful drinking (p >.001), but attachment avoidance was not (p =.11). Attachment anxiety may mediate between childhood adversity and harmful drinking (95% CI:.03-.14). Sex did not moderate the relationships between attachment anxiety and harmful drinking in the mediation relationship (women: 95% CI:.031-.179; men: 95% CI:.003.-.182). Conclusions/Importance: Attachment anxiety may mediate between childhood adversity and harmful drinking in both men and women. Attachment anxiety may be a potential therapeutic target for people with a history of childhood adversity.

RESUMO

This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9-12 (ages 13-20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the "red" category indicating a severe problem and an additional 3.3% scored in the "yellow" category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = -0.19), lower school marks (r = -0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

INTRODUCTION: Socio-economic disparities in smoking rates persist, in Ontario, despite public health care and universal tobacco control policies. Mechanisms for continuing disparities are not fully understood. Unequal access or utilization of assistance for cessation may contribute. The objective of this research was to use longitudinal data on smokers to examine the associations between socioeconomic status (SES) and access to care measures and assisted and unassisted quit attempts. METHODS: Data were taken from 3578 smokers with at least one follow-up interview participating in the Ontario Tobacco Survey (OTS). Multinomial regression models with imputed missing values were run for each measure of SES and access to care to assess the association with quitting behavior and use of assistance, unadjusted and while adjusting for smoking history and demographic covariates. RESULTS: Adjusted analyses found smokers living in areas with the lowest ethnic concentration were more likely to make an assisted quit attempt compared to unassisted quitting (RR = 1.64; 95% CI = 1.08-2.50) or making no quit attempt (RR = 1.65; 95% CI = 1.15-2.37). Smokers who reported visiting a doctor in the previous 6 months were more likely to quit with assistance versus unassisted compared to those not visiting a doctor, whether they were advised (RR = 1.89, 95% CI = 1.43-2.48) or not advised to quit (OR = 1.32, 95% CI = 1.01-1.74). Similar results were seen when comparing assisted quit attempts with no quit attempts. CONCLUSIONS: Adjusted analyses showed that quitting with assistance was unrelated to measures of SES except ethnic concentration. Physician intervention with patients who smoke is important for increasing assisted quit attempts. IMPLICATIONS: For most measures of SES there were no significant associations with either assisted or unassisted quitting adjusting for demographic and smoking history. Smokers who live in areas with the lowest ethnic concentration were most likely to use assistance as were smokers who visited their doctor and were advised to quit smoking. Interventions to increase the delivery of effective quitting methods in smokers living in areas with high ethnic concentrations and to increase physician compliance with asking and advising patients to quit may increase assisted quit attempts.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Children and youth with non-traumatic brain injury (nTBI) are often overlooked in regard to the need for post-injury health services. This study provided population-based data on their burden on healthcare services, including data by subtypes of nTBI, to provide the foundation for future research to inform resource allocation and healthcare planning for this population. METHODS: A retrospective cohort study design was used. Children and youth with nTBI in population-based healthcare data were identified using International Classification of Diseases Version 10 codes. The rate of nTBI episodes of care, demographic and clinical characteristics, and discharge destinations from acute care and by type of nTBI were identified. RESULTS: The rate of pediatric nTBI episodes of care was 82.3 per 100,000 (N = 17,977); the average stay in acute care was 13.4 days (SD = 25.6 days) and 35% were in intensive care units. Approximately 15% were transferred to another inpatient setting and 6% died in acute care. By subtypes of nTBI, the highest rates were among those with a diagnosis of toxic effect of substances (22.7 per 100,000), brain tumours (18.4 per 100,000), and meningitis (15.4 per 100,000). Clinical characteristics and discharge destinations from the acute care setting varied by subtype of nTBI; the proportion of patients that spent at least one day in intensive care units and the proportion discharged home ranged from 25.9% to 58.2% and from 50.6% to 76.4%, respectively. CONCLUSIONS: Children and youth with nTBI currently put an increased demand on the healthcare system. Active surveillance of and in-depth research on nTBI, including subtypes of nTBI, is needed to ensure that timely, appropriate, and targeted care is available for this pediatric population.

RESUMO

BACKGROUND: Adult attention deficit hyperactivity disorder (ADHD) shows a robust association with alcohol and cannabis misuse, and these relationships are expressed differently in males and females. Manifestation of specific ADHD symptom profiles, even in the absence of the full disorder, may also be related to problems with alcohol and cannabis, although these relationships have not been investigated in epidemiological studies. To address this question, we studied the sex-specific associations of ADHD symptomatology with problematic alcohol and cannabis use in a representative sample of adults aged 18 years and older residing in Ontario, Canada. METHODS: Data were obtained from the Centre for Addiction and Mental Health Monitor, an ongoing cross-sectional telephone survey, between January 2011 and December 2013. Respondents (n = 5080) reported on current ADHD symptomatology, measured using the Adult ADHD Self-Report Version 1.1 Screener (ASRS-V1.1) and four additional items, and alcohol and cannabis use, which were measured using the Alcohol Use Disorders Identification Test (AUDIT) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), respectively. Logistic regression analyses were conducted in men and women to test the association of each ADHD symptom cluster (hyperactivity, inattentiveness, impulsivity) with problematic alcohol and cannabis use. RESULTS: After controlling for age, education, and comorbid internalizing and externalizing psychopathology, hyperactive symptoms were associated with problematic alcohol use in both men and women and with problematic cannabis use in men. Impulsive symptoms were independently associated with problematic cannabis use in men. By contrast, inattentive symptomatology predicted problems with alcohol and cannabis only in women. In all models, age was negatively associated with substance misuse and externalizing behavior was positively correlated and the strongest predictor of hazardous alcohol and cannabis use. CONCLUSIONS: ADHD symptom expression in adulthood is related to concurrent hazardous use of alcohol and cannabis. Distinctive ADHD symptom profiles may confer increased risk for substance misuse in a sex-specific manner.

RESUMO

BACKGROUND: There is currently no active surveillance of metastatic and non-malignant brain tumours in Canada as well as data on the health service use of children and youth with brain tumours. The objective of this study was to identify pediatric primary, metastatic, benign, and unspecified brain tumours in Ontario, Canada and to describe their health service use from a population based perspective. METHODS: The population based healthcare administrative databases National Ambulatory Care Reporting System and the Discharge Abstract Database were used. Patients with malignant (primary and metastatic), benign, and unspecified brain tumours in acute care between fiscal year 2003/04 and 2009/10 were identified using specified International Classification of Diseases version ten codes. RESULTS: Between fiscal year 2003/04 and 2009/10, there were 4022 brain tumour episodes of care (18.4 per 100,000 children and youth). Malignant brain tumors had the highest rates of episodes of care (14.9 times higher than that of benign and 5.7 times higher than that of unspecified brain tumours). Compared to patients with malignant brain tumours, those with benign brain tumours spent a longer period of time in acute care (p < .05) and patients with unspecified brain tumours stayed in the intensive care units for a longer period of time (p < .0001) with a lower proportion were discharged home (p < .0001). CONCLUSION: Despite higher rates of malignant brain tumour episodes of care, patients with benign and unspecified brain tumours also use acute care services and post-acute services that are currently not taken into account in healthcare planning and resource allocation. Active surveillance and research of metastatic and non-malignant brain tumours that can inform the planning of healthcare services and resource allocation for this population is encouraged.

RESUMO

BACKGROUND: The case definition for traumatic brain injury (TBI) often includes 'unspecified injury to the head' diagnostic codes. However, research has shown that the inclusion of these codes leads to false positives. As such, it is important to determine the degree to which inclusion of these codes affect the overall numbers and profiles of the TBI population. The objective of this paper was to profile and compare the demographic and clinical characteristics, intention and mechanism of injury, and discharge disposition of hospitalized children and youth aged 19 years and under using (1) an inclusive TBI case definition that included 'unspecified injury to the head' diagnostic codes, (2) a restricted TBI case definition that excluded 'unspecified injury to the head 'diagnostic codes, and (3) the 'unspecified injury to the head' only case definition. METHODS: The National Ambulatory Care Reporting System and the Discharge Abstract Database from Ontario, Canada, were used to identify cases between fiscal years 2003/04 and 2009/10. RESULTS: The rate of TBI episodes of care using the inclusive case definition for TBI (2,667.2 per 100,000) was 1.65 times higher than that of the restricted case definition (1,613.3 per 100,000). 'Unspecified injury to the head' diagnostic codes made up of 39.5 % of all cases identified with the inclusive case definition. Exclusion of 'unspecified injury to the head' diagnostic code in the TBI case definition resulted in a significantly higher proportion of patients in the intensive care units (p < .0001; 18.5 % vs. 22.2 %) and discharged to a non-home setting (p < .0001; 9.9 % vs. 11.6 %). CONCLUSION: Inclusion of 'unspecified injury to the head' diagnostic codes resulted in significant changes in numbers, healthcare use, and causes of TBI. Careful consideration of the inclusion of 'unspecified injury to the head' diagnostic codes in the case definition of TBI for the children and youth population is important, as it has implications for the numbers used for policy, resource allocation, prevention, and planning of healthcare services. This paper can inform future work on reaching consensus on the diagnostic codes for defining TBI in children and youth.

RESUMO

INTRODUCTION: There are limited data on the use of electronic cigarettes (e-cigarettes) among youth, particularly with regard to the use of nicotine versus nonnicotine products. This study investigates ever use of nicotine and nonnicotine e-cigarettes and examines the demographic and behavioral correlates of e-cigarette use in Ontario, Canada. METHODS: Data for 2,892 high school students were derived from the 2013 Ontario Student Drug Use and Health Survey. This province-wide school-based survey is based on a 2-stage cluster design. Bivariate and multivariate analyses were used to investigate the factors associated with ever use of e-cigarettes. Ever use of e-cigarettes was derived from the question, "Have you ever smoked at least one puff from an electronic cigarette?" All analyses included appropriate adjustments for the complex study design. RESULTS: Fifteen percent of high school students reported using e-cigarettes in their lifetime. Most students who ever used e-cigarettes reported using e-cigarettes without nicotine (72%), but 28% had used e-cigarettes with nicotine. Male, White/Caucasian, and rural students, as well as those with a history of using tobacco cigarettes, were at greater odds of e-cigarette use. Seven percent of students who had never smoked a tobacco cigarette in their lifetime reported using an e-cigarette. Five percent of those who had ever used an e-cigarette had never smoked a tobacco cigarette. CONCLUSION: More students reported ever using e-cigarettes without nicotine than with nicotine in Ontario, Canada. This underscores the need for greater knowledge of the contents of both nicotine and nonnicotine e-cigarettes to better guide public health policies.

RESUMO

OBJECTIVE: The relationship between self-reported lifetime traumatic brain injury (TBI) and drug and alcohol use and associated harms was examined using an epidemiological sample of Canadian adolescents. SETTINGS AND DESIGN: Data were derived from a 2011 population-based cross-sectional school survey, which included 6383 Ontario 9th-12th graders who self-completed anonymous self-administered questionnaires in classrooms. Traumatic brain injury was defined as loss of consciousness for at least 5 minutes or a minimum 1-night hospital stay due to symptoms. RESULTS: Relative to high schoolers without a history of TBI, those who acknowledged having a TBI in their lifetime had odds 2 times greater for binge drinking (5+ drinks per occasion in the past 4 weeks), 2.5 times greater for daily cigarette smoking, 2.9 times greater for nonmedical use of prescription drugs, and 2.7 times greater for consuming illegal drug in the past 12 months. Adolescents with a history of TBI had greater odds for experiencing hazardous/harmful drinking (adjusted odds ratio [aOR] = 2.3), cannabis problems (aOR = 2.4), and drug problems (aOR = 2.1), compared with adolescents who were never injured. CONCLUSION: There are strong and demographically stable associations between TBI and substance use. These associations may not only increase the odds of injury but impair the quality of postinjury recovery.
