Identifying patterns of substance use and mental health concerns among adolescents in an outpatient mental health program using latent profile analysis.

Though mental health and substance use concerns often co-occur, few studies have characterized patterns of co-occurrence among adolescents in clinical settings. The current investigation identifies and characterizes these patterns among adolescents presenting to an outpatient mental health service in Ontario, Canada. Data come from cross-sectional standardized patient intake assessments from 916 adolescents attending an outpatient mental health program (January 2019-March 2021). Latent profile analysis identified patterns of substance use (alcohol, cannabis, (e-) cigarettes) and emotional and behavioral disorder symptoms. Sociodemographic and clinical correlates of these patterns were examined using multinomial regression. Three profiles were identified including: 1) low substance use and lower frequency and/or severity (relative to other patients in the sample) emotional and behavioral disorder symptoms (26.2%), 2) low substance use with higher emotional and behavioral disorder symptoms (48.2%), and 3) high in both (25.6%). Profiles differed in sociodemographic and clinical indicators related to age, gender, trauma, harm to self, harm to others, and service use. Experiences of trauma, suicide attempts, and thoughts of hurting others increased the odds of adolescents being in the profile high in both substance use and symptoms compared to other profiles. These findings further document the high rates of substance use in adolescents in mental health treatment and the profiles generally map onto three out of four quadrants in the adapted four-quadrant model of concurrent disorders, indicating the importance of assessing and addressing substance use in these settings.

Individual- and school-level patterns of substance use and mental health symptoms in a population-based sample of secondary students: A multilevel latent profile analysis.

BACKGROUND: While substance use and mental health symptoms commonly co-occur among adolescents, few population-level studies have examined profiles of co-occurrence to inform tailored prevention and early interventions. METHODS: A multilevel latent profile analysis was conducted on a representative sample of 11,994 students in 68 secondary schools to: 1) identify distinct profiles of co-occurring substance use and mental health symptoms; 2) identify types of schools based on student profiles; and 3) explore school correlates of student profiles and school types, including school climate, belonging, and safety. RESULTS: Five student profiles and three school types were identified. Among students, 57.6 % were in a low substance use and mental health profile, 22.5 % were in a high mental health but low substance use profile, 9.7 % were in a heavy drinking and cannabis use profile, 3.7 % were in a heavy drinking and smoking profile, and 6.5 % were in a high substance use and mental health profile. Positive school climate, belonging, and safety increased the odds of students being in the low profile, with belonging yielding larger effects among females. Among schools, 28 % had low, 57 % had moderate, and 15 % had high levels of student substance use and comorbid mental health symptoms. Rural schools were disproportionately represented in higher risk school types. CONCLUSIONS: The identified student substance use and mental health symptom profiles can serve as targets for tailored prevention and early interventions. Results support examining school-based interventions targeting school climate, belonging, and safety with potential benefits to both substance use and mental health.

Examining the relationships between parent experiences and youth self-reports of slapping/spanking: a population-based cross-sectional study.

BACKGROUND: Slapping/spanking is related to a number of poor health outcomes. Understanding what factors are related to the increased or decreased use of spanking/slapping is necessary to inform prevention. This study used a population-based sample to determine the prevalence of slapping/spanking reported by youth; the relationship between sociodemographic factors and slapping/spanking; and the extent to which parental exposures to victimization and maltreatment in childhood and current parental mental health, substance use and family circumstances, are associated with youth reports of slapping/spanking. METHODS: Data were from the 2014 Ontario Child Health Study, a provincially representative sample of households with children and youth aged 4-17 years. Self-reported lifetime slapping/spanking prevalence was determined using a sub-sample of youth aged 14-17 years (n = 1883). Parents/primary caregivers (i.e., person most knowledgeable (PMK) of the youth) self-reported their own childhood experiences including bullying victimization, slapping/spanking and child maltreatment, and current mental health, substance use and family circumstances including mental health functioning and emotional well-being, alcohol use, smoking, marital conflict and family functioning. Analyses were conducted in 2018. RESULTS: Living in urban compared to rural residence and family poverty were associated with decreased odds of slapping/spanking. PMK childhood experiences of physical and verbal bullying victimization, spanking, sexual abuse, emotional abuse, and exposure to physical intimate partner violence were associated with increased odds of youth reported slapping/spanking (adjusted odds ratio [AOR] ranged from 1.33-1.77). PMK experiences of physical abuse and exposure to emotional/verbal intimate partner violence in childhood was associated with decreased odds of youth reported slapping/spanking (AOR = 0.72 and 0.88, respectively). PMK's higher levels of marital conflict, languishing to moderate mental health functioning and emotional well-being, and moderate or greater alcohol use were associated with increased odds of youth reported slapping/spanking (AOR ranged from 1.36-1.61). CONCLUSIONS: It may be important to consider parent/primary caregiver's childhood experiences with victimization and maltreatment along with their current parental mental health, substance use and family circumstances when developing and testing strategies to prevent slapping/spanking.

Sex Differences in the Association Between Cyberbullying Victimization and Mental Health, Substance Use, and Suicidal Ideation in Adolescents.

OBJECTIVE: To examine sex differences in the association between cyberbullying victimization and mental health (psychological distress and delinquency), substance use-related outcomes (drug and tobacco use, binge drinking), and suicide ideation among adolescents. METHOD: Data were obtained from the Ontario Student Drug Use and Health Survey (OSDUHS; 2013, N=10,272, grade 7 to 12). The sample for analysis included 4,940 students with a mean age of 15.1 years (43.3% male). A series of multi-level, binary, logistic regression models were conducted separately for female and male adolescents to quantify the strength of associations between cyberbullying victimization and study outcomes, after accounting for traditional forms of bullying and demographic covariates. RESULTS: Female adolescents reported significantly higher prevalence of cyberbullying victimization (once, 9.4%; twice or more, 13.3%) as compared with male adolescents (once, 8.3%, twice or more, 7.8%). Exposure to cyberbullying victimization was associated with an increased odds for psychological distress, suicide ideation, and delinquency among both female and male adolescents (adjusted odds ratios ranged from 1.76 to 4.63); although, the effects were more pronounced in females. Among females, but not males, the odds of reporting psychological distress, suicide ideation, and delinquency increased (in a step-wise fashion) with more frequent exposure to cyberbullying victimization. Cyberbullying victimization was associated with an increased odds of adolescent substance use only among females. CONCLUSION: Adolescents exposed to cyberbullying victimization demonstrate an increased odds of poorer mental health, substance use outcomes, and suicide ideation. The current study reveals increased risk among female adolescents as compared with male adolescents. These findings lend support for the need to develop and evaluate targeted preventative interventions specifically tailored for female and male adolescents.

Community- and individual-level factors associated with smoking and heavy drinking among Aboriginal people in Canada.

OBJECTIVES: 1) To examine the association between place of residence (i.e., on- versus off-communities and between provinces) and daily smoking and heavy drinking among Aboriginal people in Canada; and 2) to identify community- and individual-level factors that may account for these associations. METHODS: Data were from the Aboriginal Peoples Survey (2001). The sample included 52,110 Aboriginal people (≥ 15 years of age). Community-level variables included: place of residence, community socio-economic status (SES) and perceived community social problems. Individual-level variables included: age, sex, education, income, employment status, marital status, Aboriginal heritage and social support. Multilevel logistic regressions were conducted to analyze the data. RESULTS: Living in First Nations communities (compared with living off-communities) was associated with daily smoking, and this association was accounted for by perceived community social problems. However, the association between Inuit communities and daily smoking remained after controlling for all covariates (odds ratio (OR) = 1.97, 95% confidence intervals (CI) = 1.44-2.70). Residence in First Nations communities was associated with heavy drinking (OR = 1.54, 95% CI = 1.17-2.04), however this risk became evident only after controlling for community SES, which was also positively associated with heavy drinking (OR = 1.46, 95% CI = 1.26-1.69). Compared with Saskatchewan, Aboriginal people in Atlantic Provinces (OR = 2.80, 95% CI = 2.08-3.78) or Territories (OR = 1.39, 95% CI = 1.01-1.92) were more likely to engage in heavy drinking. CONCLUSION: Studies are needed to better understand the increased risk for smoking in Inuit communities and heavy drinking in First Nations communities, Atlantic Provinces and Territories, and to identify possible reasons for the positive association between community SES and heavy drinking among Aboriginal people.

Maternal smoking, biofuel smoke exposure and child height-for-age in seven developing countries.

BACKGROUND: Children are at high risk of exposure to environmental tobacco smoke and biofuel smoke at home in developing countries. This study examines whether exposure to cigarette and biofuel smoke is associated with height-for-age of children (0-59 months) in seven developing countries. METHODS: The data are from Demographic and Health Surveys conducted in Cambodia, Dominican Republic, Haiti, Jordan, Moldova, Namibia and Nepal between 2005 and 2007. The respondents were women (15-49 years) and their children in seven countries (n = 28 439), and men (15-59 years) from four countries. The outcome is a physical measurement of child height-for-age in standard deviation units. RESULTS: Multilevel regression analysis showed that the country of residence modified the association between maternal smoking and child height-for-age. Exposure to maternal smoking was associated negatively with child height-for-age in Cambodia, Namibia and Nepal, whereas it was not in other countries. Multilevel regression analysis revealed that biofuel smoke exposure was associated with a decrease in child height-for-age [b = -0.13, 95% confidence interval (CI) = -0.19 to -0.07, P < 0.001]. No interaction was found between country of residence and biofuel smoke exposure. Multinomial logistic regression results showed that biofuel smoke exposure was associated with both stunting [odds ratio (OR) = 1.25, 95% CI = 1.08-1.44, P = 0.002) and severe stunting (OR = 1.27, 95% CI = 1.02-1.59, P = 0.04), after controlling for covariates. CONCLUSION: The findings suggest that exposure to maternal smoking and biofuel smoke may contribute to growth deficiencies in young children. Programmes are needed to ensure smoke-free home environments for children.

The Brief Child and Family Phone Interview (BCFPI): 2. Usefulness in screening for child and adolescent psychopatholog.

BACKGROUND: This study examines the use of the Brief Child and Family Phone Interview (BCFPI) to screen for childhood psychiatric disorder based on Diagnostic Interview Schedule for Children Version IV (DISC-IV) classifications of attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), conduct disorder (CD), separation anxiety (SAD), generalized anxiety (GAD) and major depression (MDD). METHODS: Data for analysis come from a sample of 399 children and adolescents aged 5-17 years old referred to child mental health outpatient services in three Ontario cities. Mothers were administered the BCFPI on three occasions: baseline, 2 and 13 months; and the DISC-IV on two occasions: 1 and 12 months. RESULTS: Based on kappa, test-retest reliability for disorders classified by the BCFPI exceeded .50 for all conditions except MDD (.45). In receiver operating characteristic (ROC) analysis, area-under-the-curve (AUC) estimates for BCFPI scale score associations with DISC-IV classifications of disorder exceeded .80 for CD, ODD, ADHD and SAD; and were lower for GAD (.76) and MDD (.75). In stratified analyses, there were no statistically significant differences in AUC estimates for boys versus girls and 5 to 11 versus 12 to 17-year-olds. CONCLUSIONS: Classifications of childhood disorder derived from the BCFPI provided a reasonable approximation to disorders classified by the DISC-IV administered by lay interviewers.

Adolescent tobacco and cannabis use: young adult outcomes from the Ontario Child Health Study.

BACKGROUND: This study examines the longitudinal associations between adolescent tobacco and cannabis use and young adult functioning. METHODS: Data for analysis come from the Ontario Child Health Study (OCHS), a prospective study of child health, psychiatric disorder and adolescent substance use in a general population sample that began in 1983, with follow-ups in 1987 and 2001. The sample for analysis includes 1,282 individuals who were between the ages of 12 and 16 years during the original OCHS in 1983 or the first follow-up in 1987 and returned for the 2001 follow-up. RESULTS: Tobacco use in adolescence and continued use in adulthood is associated with increased risk for poorer functioning across multiple domains, including physical health and life satisfaction (.62 and .66 standard units lower, respectively), depression (Odds Ratio = 3.44), personal income ($7,281 less per year) and years of education (2.29 years lower). Cannabis use is associated with a reduced set of adverse outcomes and the magnitude of the effects is weaker. CONCLUSIONS: The long-term risks associated with adolescent tobacco and cannabis use speak to the importance of prevention and early intervention.

The influence of economic development level, household wealth and maternal education on child health in the developing world.

This study estimates the relative importance to child health (indicated by weight and height for age) of economic development level [gross domestic product (GDP) converted to international dollars using purchasing power parity (PPP) rates: GDP-PPP], household wealth and maternal education and examines the modifying influence of national contexts on these estimates. It uses information collected from mothers aged 15-49-years participating in Demographic Health Surveys (DHS) conducted in 42 developing countries. In multilevel regression models, the three study variables exhibited strong independent associations with child health: GDP-PPP accounted for the largest amount of unique variation, followed by maternal education and household wealth. There was also substantial overlap (shared variance) between maternal education and the other two study variables. The regressions of child health on household wealth and maternal education exhibited substantial cross-national variation in both strength and form of association. Although higher education levels were associated with disproportionately greater returns to child health, the pattern for household wealth was erratic: in many countries there were diminishing returns to child health at higher levels of household wealth. We conclude that there are inextricable links among different strategies for improving child health and that policy planners, associating benefits with these strategies, must take into account the strong moderating impact of national context.

Tobacco use among immigrant and nonimmigrant adolescents: individual and family level influences.

PURPOSE: To identify individual and family level characteristics that might explain differences in rates of tobacco use among immigrant and nonimmigrant adolescents. METHODS: Data for analysis come from a probability sample of 5401 adolescents aged 12-18 years participating in the Ontario Health Survey (OHS). Three groups were compared: (a) adolescents born in Canada to Canadian-born parents (n = 3886), (b) adolescents born in Canada to immigrant parents (n = 1233), and (c) adolescents born outside of Canada (n = 282). Discrete, multilevel logistic regression was used in the analysis. RESULTS: Adolescents born outside of Canada report the lowest rates of tobacco use, despite greater economic hardship. A negative association emerges between family socioeconomic status and tobacco use among adolescents born in Canada but not among adolescents born outside of Canada. Immigrant youth are less likely to affiliate with peers who smoke and are more likely to come from families where parents do not smoke: these differences partially explain the decreased rates of tobacco use among immigrant adolescents. CONCLUSIONS: Although subject to greater economic hardship, immigrant youth are less likely to engage in tobacco use. Protective factors associated with immigrant family life, such as lower rates of parental tobacco use and less exposure among immigrant adolescents to peers who smoke, may counteract some of the negative effects of poverty and social hardship. Future research should begin to address the processes that lead to adaptive outcomes among adolescents from immigrant families, despite greater exposure to social disadvantage.
