Introduction: The COVID-19 pandemic intensified the impact of risk factors for adolescent mental health, including financial worry. Social support has shown to protect from negative mental health during times of stress. We examined the effect of financial worry on changes in anxiety and depression symptoms among Canadian adolescents prior to and during the pandemic, and assessed whether social support from family and friends moderated any changes. Methods: We analyzed 2-year linked data from the 2018/19 (pre-pandemic) and 2020/21 (during-pandemic) waves of the COMPASS study, with reports from 12 995 Canadian secondary school students. A series of multilevel linear regressions were conducted to examine the main hypotheses under study. Results: Students scored an average (SD) of 7.2 (5.8) on the anxiety (GAD-7) and 10.0 (6.5) on the depression (CESD-10) scales; 16.1% reported they experienced financial worry during the pandemic. Financial worry was a strong and significant predictor of increased anxiety scores (+1.7 score between those reporting "true/mostly true" versus "false/mostly false") during the pandemic, but not for depression scores. Low family and friend support were associated with anxiety, and low family support was associated with depression. No significant interactions were detected between social support and financial worry. Conclusion: Pandemic-related financial worry was significantly associated with anxiety in our large sample of Canadian adolescents. Clinical and public health initiatives should be aware of adolescents' financial worry and its associations with anxiety during times of crisis. [ABSTRACT FROM AUTHOR]

BACKGROUND: Income inequality is theorized to impact health. However, evidence among adolescents is limited. This study examined the association between income inequality and health‐related school absenteeism (HRSA) in adolescents. METHODS: Participants were adolescents (n = 74,501) attending secondary schools (n = 136) that participated in the 2018‐2019 wave of the COMPASS study. Chronic (missing ≥3 days of school in the previous 4 weeks) and problematic (missing ≥11 days of school in the previous 4 weeks) HRSA was self‐reported. Income inequality was assessed via the Gini coefficient at the census division (CD) level. Multilevel modeling was used. RESULTS: Greater income inequality was associated with a higher likelihood of chronic and problematic HRSA (chronic: OR = 1.17, 95% CI: 1.06, 1.30; problematic: OR = 1.29, 95% CI 1.11 to 1.50). Increased predicted probabilities for Problematic HRSA were observed at greater degrees of income inequality among students who identified as either white, black, Latinx, or mixed, while protective associations were observed among students who identified as Asian or other. No associations were modified by gender. CONCLUSION: Income inequality demonstrated unfavorable associations with HRSA, which was modified by racial identity. [ABSTRACT FROM AUTHOR]

Youth overweight and obesity (OWOB) surveillance often uses body mass index (BMI) derived from self-reported height and weight, but these measures can suffer from high proportions of missing data. Complete case analysis (CCA) is the most common approach to handle missing data, but this approach can introduce bias if missing data are not missing completely at random. Using BMI and related covariate data from 36,546 female and 37,126 male youth aged 12–19 years who participated in the COMPASS study in 2018/19, where approximately 30% of BMI data were missing, results and inference were compared between CCA and multiple imputation (MI) approaches to examine associations with youth BMI. Results of regression joint models showed contrasting findings between MI and CCA, highlighting that appropriate methodological choices in the handling of missing data are essential in youth OWOB research and that choices can impact research inference and thereby associated policy and programming recommendations.

Background: Several recent global events may have impacted adolescent sleep and exacerbated pre-existing disparities by social positions (i.e., social roles, identity or sociodemographic factors, and/or group memberships that are associated with power and oppression due to the structures and processes in a given society at given time). Current understanding of sleep among adolescents is critical to inform interventions for a more equitable future, given the short and long-term consequences of inadequate sleep on health and well-being. This study aimed to provide contemporary evidence on sleep disparities by key social positions among adolescents in Canada., Methods: Cross-sectional analyses were conducted using self-reported data collected during 2020-2021 (the first full school year after the COVID-19 pandemic onset) from 52,138 students (mean [SD] age = 14.9 [1.5]) attending 133 Canadian secondary schools. Multiple regression models were used to test whether sleep quality (how well students slept during past week), duration (weekday, weekend, weighted daily average), and guideline adherence (8-10 h/day) differed by sex and gender, race and ethnicity, and socioeconomic status (SES)., Results: Females reported a mean [95% CI] difference of -1.7 [-3.7, 0.4] min/day less sleep on weekdays than males, but 7.1 [4.5, 9.6] min/day more sleep on weekends, resulting in no difference in average daily sleep between males and females. Females were less likely to report good quality sleep compared to males (AOR = 0.57 [0.54, 0.60]). SES followed a generally monotonic trend where higher scores were associated with more sleep on weekdays (Δ highest: lowest = -28.6 [-39.5, -17.6]) and weekends (Δ highest: lowest = -17.5 [-3.8, -31.2]) and greater likelihood of higher sleep quality (AOR highest: lowest = 3.04 [2.35, 3.92]). Relative to White adolescents, weekday and average daily sleep duration were lower among all other racial identities; mean differences ranged from ∼ 5-15 min/day, with Black students reporting the least sleep., Conclusions: Differences in sleep duration and quality were most profound among adolescents from the lowest and highest SES. Racial disparities were more evident on weekdays. Compensatory weekend sleep appears more pronounced in females than males. Addressing sleep inequities is critical, as a robust predictor of multiple health outcomes., (© 2024. The Author(s).)

Background: Public health unit (PHU) engagement in schools is important for promoting wellness in students. We aimed to investigate if PHU engagement with schools may have provided protection against the risk of depression and anxiety in students during the COVID-19 pandemic., Methods: We used longitudinal data from the Cannabis, Obesity, Mental health, Physical activity, Alcohol use, Smoking and Sedentary behaviour survey between the 2018/19 and 2020/21 academic years. Multilevel models were used to assess the association between PHU engagement with school mental health programs prior to the COVID-19 pandemic and depressive (Center for Epidemiologic Studies Depression scale Revised) and anxiety symptoms (Generalized Anxiety Disorder scale) during the COVID-19 pandemic., Results: The sample included 23 894 students across 104 secondary schools in British Columbia, Alberta, Ontario and Quebec. In confounder-adjusted models, PHU engagement before the pandemic was not associated with student depressive symptoms (B = -0.01, 95% CI = -0.04, 0.02), but was protective against anxiety symptoms (B = -0.03, -0.06, 0.001) during the COVID-19 pandemic., Discussion: The results highlight that PHU engagement with mental health programming in schools was protective against anxiety for students during the COVID-19 pandemic. The findings support the importance of PHU engagement for improving student mental health and pandemic recovery., (© The Author(s) 2024.
