RESUMEN
OBJECTIVE: To examine specific sleep characteristics of adults living in Canada according to sex, gender, ethnoracial background, socioeconomic status, immigration status, sexual orientation, and language spoken at home. METHODS: This cross-sectional and nationally representative study used self-reported data from the 2021 Canadian Community Health Survey (n = 39,346 adults aged 18 years and older). Sleep characteristics (sleep duration, nighttime insomnia symptoms, unrefreshing sleep, and difficulty staying awake) were assessed and compared across groups. RESULTS: Females were more likely than males to report nighttime insomnia symptoms (23.1% vs. 14.8%) and unrefreshing sleep (17.2% vs. 13.5%). The same was also observed for gender identity. Although White respondents were more likely to meet sleep duration recommendations (58.3%), they had the highest prevalence of nighttime insomnia symptoms (20.9%) compared to respondents with other ethnoracial backgrounds. Respondents coming from lower socioeconomic backgrounds were more likely to report poorer sleep compared to those coming from higher socioeconomic backgrounds. Insomnia symptoms were lower among immigrants (13.9%) compared to nonimmigrants (21.1%). Respondents with a sexual orientation not classified as heterosexual, gay, or lesbian reported poorer sleep. Finally, for language spoken at home, those who responded "French only" were more likely to meet sleep duration recommendations (64.1%) and were less likely to report unrefreshing sleep (8.8%). Nighttime insomnia symptoms were the lowest among those who reported speaking a language other than French or English at home (9.5%). CONCLUSION: This study highlights important sleep disparities among Canadians. Future intervention strategies should aim to reduce sleep health disparities.

BACKGROUND: Adolescence is a critical period for development, with many risk factors resulting in long-term health consequences, particularly regarding mental health. The purpose of this study was to examine the associations between problem technology use, life stress, and self-esteem in a representative sample of adolescents residing in Ontario, Canada. METHODS: Self-reported data were obtained from a cross-sectional sample of 4,748 students (57.9% females) in grades 9 to 12 (mean age: 15.9 ± 1.3 years) who participated in the 2019 Ontario Student Drug Use and Health Survey. Problem technology use was measured using the 6-item Short Problem Internet Use Test, life stress was assessed using an item from the British Columbia Adolescent Health Survey and self-esteem was assessed using a global measure from the Rosenberg Self-Esteem Scale. Ordinal logistic regression models were adjusted for age, sex, ethnoracial background, subjective socioeconomic status, body mass index z-score, tobacco cigarette smoking, alcohol consumption and cannabis use. RESULTS: We found that 18.3% of participants reported symptoms of moderate-to-high problem technology use, although symptoms were more common in females than males (22% vs. 14.7%, respectively). Moderate-to-high problem technology use was associated with 2.04 (95% CI: 1.77-2.35) times higher odds of reporting high life stress and 2.08 (95% CI: 1.76-2.45) times higher odds of reporting low self-esteem compared to all other response options. CONCLUSIONS: Findings from this study show that problem technology use is strongly associated with higher life stress and lower self-esteem in adolescents. This study supports the importance of developing and implementing effective strategies that help to mitigate the adverse effects of problem technology use on adolescent mental health.

BACKGROUND: Cannabis use and nonmedical use of prescription opioids are consumed by a small to moderate number of adolescents. However, little is known about their combined influence on mental health in this age group. This study examined the association between cannabis use, nonmedical use of prescription opioids, or both with serious psychological distress among adolescents and tested if sex could moderate these associations. METHODS: We based our analyses on cross-sectional data from the 2019 Ontario Student Drug Use and Health Survey, a provincially representative sample of students in grades 7 through 12 (aged 11-20 years or older) across Ontario, Canada (n= 7097; mean age: 15.2 ± 1.2 years). Logistic regression analyses were adjusted for important covariates. RESULTS: We found that 20.5% reported cannabis use only, 5.8% reported opioid use only, and 5% reported both cannabis and opioid use. Cannabis use only (odds ratio [OR]:1.91; 95% confidence interval [CI]:1.53-2.37), opioid use only (OR: 2.21; 95% CI: 1.63-3.00), and both cannabis and opioid use (OR: 3.24; 95% CI: 2.25-4.66) were associated with greater odds of serious psychological distress after adjustment for covariates. Associations were similar for males and females. CONCLUSION: The use of both cannabis and opioids is significantly associated with serious psychological distress among adolescents. Adolescents who use both cannabis and opioids represent a small and vulnerable group that should be targeted in future interventions against mental health problems. Health professionals should consider screening for polysubstance use, especially when working with adolescents who use cannabis.

OBJECTIVE: Social media use has become ubiquitous among schoolchildren. This study examined the association of social media use and posting regret with self-esteem among middle and high school students, and tested whether school type (i.e., middle vs. high school) could moderate these associations. METHODS: Data on 6944 schoolchildren (mean age: 15.2 ± 1.8 years) were derived from the 2019 cycle of the Ontario Student Drug Use and Health Survey, a biennial repeated cross-sectional survey of students in grades 7 through 12 across Ontario, Canada. Students self-reported time spent using social media, regret of posting on social media, and their self-esteem. Ordinal logistic regression analyses were adjusted for age, sex, subjective socioeconomic status, ethnoracial background, and body mass index z-score. RESULTS: The proportional odds model showed that middle (OR: 2.36; 95% CI: 1.65-3.36) and high school (OR: 1.72; 95% CI: 1.44-2.06) students with daily social media use of 5 h or more have higher odds of lower self-esteem across the categories of self-esteem. However, daily use of 3 to 4 h was associated with lower self-esteem among middle school students (OR: 1.52; 95% CI: 1.14-2.04), but not among their high school counterparts (OR: 1.13; 95% CI: 0.94-1.35). Posting regret was associated with lower self-esteem in high school students, but not in middle school students. CONCLUSION: Results suggest that heavy social media use and posting regret are associated with lower self-esteem among adolescents, and that younger students could be more vulnerable than their older counterparts.
RéSUMé: OBJECTIF: L'utilisation des médias sociaux est devenue omniprésente chez les écoliers. Cette étude a examiné l'association entre l'utilisation des médias sociaux et les regrets liés à l'affichage et l'estime de soi chez les élèves de niveau intermédiaire et secondaire, et a vérifié si le niveau scolaire (c'est-à-dire intermédiaire comparé au secondaire) pouvait modérer ces associations. MéTHODES: Les données concernant 6 944 écoliers (âge moyen : 15,2 ± 1,8 ans) proviennent du cycle 2019 de l'Enquête sur la consommation de drogues et la santé des élèves de l'Ontario, une enquête transversale répétée de façon bisannuelle menée auprès des élèves de la 7e à la 12e année dans l'ensemble de l'Ontario, au Canada. Les élèves ont déclaré eux-mêmes le temps passé à utiliser les médias sociaux, le regret de publier sur les médias sociaux et leur estime de soi. Les analyses de régression logistique ordinale ont été ajustées en fonction de l'âge, du sexe, du statut socioéconomique subjectif, de l'origine ethnoraciale et du score z de l'indice de masse corporelle. RéSULTATS: Le modèle des cotes proportionnelles a montré que les élèves des écoles intermédiaires (RC : 2,36; IC à 95% : 1,653,36) et secondaires (RC : 1,72; IC à 95% : 1,442,06) qui utilisent quotidiennement les médias sociaux pendant 5 heures ou plus sont plus susceptibles d'avoir une faible estime de soi dans toutes les catégories de l'estime de soi. Cependant, une utilisation quotidienne de 3 à 4 heures était associée à une plus faible estime de soi chez les élèves de niveau intermédiaire (RC : 1,52; IC à 95% : 1,142,04), mais pas chez leurs homologues du secondaire (RC : 1,13; IC à 95% : 0,941,35). Le fait d'avoir des regrets était associé à une plus faible estime de soi chez les élèves du secondaire, mais pas chez ceux du niveau intermédiaire. CONCLUSION: Les résultats suggèrent que l'utilisation intensive des médias sociaux et les regrets liés à l'affichage sont associés à une faible estime de soi chez les adolescents, et que les jeunes élèves pourraient être plus vulnérables que leurs homologues plus âgés.

Background: Despite increasing evidence that social media use is associated with adolescents' mental well-being, little is known about the role of various factors in modifying the effect of this association during adolescence. This study examined the association between social media use and psychological distress among adolescents and explored whether sex, age, and parental support moderate this association. Methods: Data came from a representative sample of middle and high school students in Ontario, Canada. Cross-sectional analyses included 6,822 students derived from the 2019 Ontario Student Drug Use and Health Survey. Results: Our results showed that 48% of adolescents used social media for 3 h or more per day, and 43.7% had moderate to severe psychological distress, with a higher prevalence among females (54%) than males (31%). After adjustment for relevant covariates, heavy social media use (≥3 h/day) was associated with increased odds of severe psychological distress [odds ratio (OR): 2.01; 95% confidence interval (CI):1.59-2.55]. The association of social media use with psychological distress was modified by age (p < 0.05) but not sex or parental support. The association was stronger among younger adolescents. Conclusion: Heavy social media use is associated with higher levels of psychological distress, with younger adolescents being the most vulnerable. Longitudinal studies are recommended for future research to examine in more depth the role of sex, age, and parental support in the association between social media use and psychological distress to better determine the strength and of the association.

The economic cost associated with low muscle strength in Canadian adults is unknown. The total annual economic burden of low muscle strength in Canadian adults represents 2.2% of the overall burden of illness costs in 2021. We estimated that $546 million per year would be saved if the prevalence of low handgrip strength was reduced by 10%.

Background: Evidence examining the longitudinal associations between different types of screen behaviours and mental health among adolescents is limited. The present study examined the association between five types of screen behaviours and symptoms of anxiety and depression one year later. This study also assessed how changes in screen time were associated with changes in anxiety and depressive symptoms and whether the observed relationships were moderated by sex. Methods: Longitudinal data of 17,174 students in grades 9-12 (53.5% females; mean age: 15.1 ± 0.9 years) attending high schools in Canada from two waves (year 6: 2017/18, year 7: 2018/19) of the COMPASS study were analyzed. Leisure screen time and mental health measures were self-reported. To test if the associations between screen time and anxiety, and depression vary by sex, two-way interactions were examined for sex. Analyses accounted for school clustering, race/ethnicity, sex, age, income, body mass index z-score, and previous year anxiety and depression symptoms. Results: There were significant longitudinal associations between time spent on each type of screen and subsequent anxiety and depression symptoms. The strength of the associations varied by type of screen behaviour. Interaction analysis indicated a sex difference for television viewing and anxiety and depression symptoms, and internet surfing and anxiety symptoms. A dose-response relationship was observed between phone talking and anxiety symptoms. Beta estimates indicated that an increase in screen duration was associated with a further increase in anxiety and depression symptoms. Conclusion: Higher screen time was longitudinally associated with higher anxiety and depression symptoms at one-year follow-up in adolescents. Time-change associations between screen usage and depressive and anxiety symptoms were observed. Also, associations differed based on sex and screen type, whereby greater increases in screen use predicted greater emotional distress. Findings from this prospective analysis suggest that screen time is an important determinant of anxiety and depressive symptoms among adolescents. Future studies are recommended to help inform programs promoting screen time reduction with a goal to enhance adolescents' mental health.

OBJECTIVE: To estimate health care and health-related productivity costs associated with excessive sedentary behaviour (> 8 h/day and > 9 h/day) in Canadian adults. METHODS: Three pieces of information were used to estimate costs: (1) the pooled relative risk estimates of adverse health outcomes consistently shown to be associated with excessive sedentary behaviour, gathered from meta-analyses of prospective cohort studies; (2) the prevalence of excessive sedentary behaviour in Canadian men and women, obtained using waist-worn accelerometry in a nationally representative sample of adults (Canadian Health Measures Survey 2018-2019); and (3) the direct (health care) and indirect (lost productivity due to premature mortality) costs of the adverse health outcomes, selected using the Economic Burden of Illness in Canada 2010 data. The 2010 costs were then adjusted to 2021 costs to account for inflation, population growth, and higher average earnings. A Monte Carlo simulation was conducted to account for uncertainty in the model. RESULTS: The total costs of excessive sedentary behaviour in Canada were $2.2 billion (8 h/day cut-point) and $1.8 billion (9 h/day cut-point) in 2021, representing 1.6% and 1.3% of the overall burden of illness costs, respectively. The two most expensive chronic diseases attributable to excessive sedentary behaviour were cardiovascular disease and type 2 diabetes. A 10% decrease in excessive sedentary behaviour (from 87.7% to 77.7%) would save an estimated $219 million per year in costs. CONCLUSION: Excessive sedentary behaviour significantly contributes to the economic burden of illness in Canada. There is a need for evidence-based and cost-effective strategies that reduce excessive sedentary behaviour in the population.
RéSUMé: OBJECTIF: Estimer le coût des soins de santé et le coût de productivité lié à la santé associés au comportement sédentaire excessif (> 8 heures/jour et > 9 heures/jour) chez les Canadiennes et les Canadiens adultes. MéTHODE: Trois informations ont servi à estimer ces coûts : 1) les estimations combinées du risque relatif des résultats sanitaires indésirables uniformément associés au comportement sédentaire excessif, collectées à partir de méta-analyses d'études prospectives de cohortes; 2) la prévalence du comportement sédentaire excessif chez les Canadiennes et les Canadiens, obtenue à l'aide d'un accéléromètre porté à la taille par un échantillon représentatif national d'adultes (Enquête canadienne sur les mesures de la santé 2018-2019); et 3) les coûts directs (soins de santé) et indirects (perte de productivité due à la mortalité prématurée) des résultats sanitaires indésirables sélectionnés, d'après les données du Fardeau économique de la maladie au Canada de 2010. Les coûts de 2010 ont ensuite été ajustés aux coûts de 2021 pour tenir compte de l'inflation, de la croissance démographique et de la hausse moyenne des revenus. Nous avons effectué une simulation de Monte-Carlo pour tenir compte de l'incertitude du modèle. RéSULTATS: Les coûts totaux du comportement sédentaire excessif au Canada étaient de 2,2 milliards de dollars (point de coupure de 8 heures/jour) et de 1,8 milliard de dollars (point de coupure de 9 heures/jour) en 2021, ce qui représente 1,6 % et 1,3 % du fardeau global des coûts des maladies, respectivement. Les deux maladies chroniques les plus chères imputables au comportement sédentaire excessif étaient les maladies cardiovasculaires et le diabète de type 2. Une baisse de 10 % du comportement sédentaire excessif (de 87,7 % à 77,7 %) économiserait environ 219 millions de dollars de coûts par année. CONCLUSION: Le comportement sédentaire excessif contribue de façon significative au fardeau économique de la maladie au Canada. Il nous faut des stratégies fondées sur les preuves et efficaces par rapport au coût pour réduire le comportement sédentaire excessif dans la population.

The objective of this study was to estimate health care and health-related productivity costs associated with low cardiorespiratory fitness (CRF) in Canadian adults. We also estimated costs that would be avoided by a 10 percentage point prevalence reduction in low CRF. A prevalence-based approach was used to estimate the economic costs associated with low CRF. Three pieces of information were used: (1) the pooled relative risk estimates of adverse health outcomes consistently associated with low CRF obtained from meta-analyses of prospective cohort studies; (2) the prevalence of low CRF in Canadian men and women obtained from a nationally representative sample; and (3) the direct (health care) and indirect (lost productivity due to premature mortality) costs of the adverse health outcomes based on the Economic Burden of Illness in Canada data. We estimated the total annual economic burden of low CRF in Canadian adults at CAD$3.6 billion, representing 2.7% of the overall Canadian burden of illness costs in 2021. The three most expensive chronic diseases attributable to low CRF were type 2 diabetes (CAD$1.3 billion), heart disease (CAD$701 million), and depression/anxiety (CAD$565 million). Prescription drug expenditures and hospital care expenditures were the main contributors to the total economic burden. An absolute 10% reduction in the prevalence of low CRF (from 45.5% to 35.5%) would save an estimated CAD$644 million per year in costs. In conclusion, low CRF is an important contributor to the economic burden of illness in Canada. Evidence-based and cost-effective strategies that aim to increase CRF at the population level may help alleviate health care costs and improve health.

OBJECTIVE: To estimate health care and productivity costs associated with insomnia symptoms in Canadian adults. METHODS: Three pieces of information were needed to calculate estimates based on a prevalence-based approach: (1) the pooled relative risk estimates of health outcomes consistently associated with insomnia symptoms obtained from recent meta-analyses of prospective cohort studies; (2) the direct (health care) and indirect (lost productivity due to premature mortality) costs of these health outcomes using the Economic Burden of Illness in Canada information; and (3) the prevalence of insomnia symptoms in Canadian men (18.1%) and women (29.5%) obtained from a nationally-representative survey. RESULTS: The direct, indirect, and total costs of insomnia symptoms in Canada in 2021 were $1.9 billion, $12.6 million, and $1.9 billion, respectively. This value represents 1.9% of the overall burden of illness costs for 2021 in Canada. The 2 most expensive chronic diseases attributable to insomnia symptoms were type 2 diabetes ($754 million) and depression ($706 million). The main contributor to the costs for type 2 diabetes and depression was prescription drugs. A 5% decrease in insomnia symptoms (from 23.8% to 18.8%) would result in an estimated $353 million in avoided costs while a 5% increase in insomnia symptoms (from 23.8% to 28.8%) would result in an estimated $333 million in additional expenditures yearly. CONCLUSIONS: Insomnia symptoms greatly contribute to the economic burden of illness in Canada. Reducing the prevalence of insomnia symptoms would reduce its societal burden.

The direction of the association between discretionary screen time (DST) and sleep in the adult population is largely unknown. We examined the bidirectional associations of DST and sleep patterns in a longitudinal sample of adults in the general population. A total of 31,361 UK Biobank study participants (52% female, 56.1 ± 7.5 years) had two repeated measurements of discretionary screen time (TV viewing and leisure-time computer use) and self-reported sleep patterns (five sleep health characteristics) between 2012 and 2018 (follow-up period of 6.9 ± 2.2 years). We categorised daily DST into three groups (low, <3 h/day; medium, 3-4 h/day; and high, >4 h/day), and calculated a sleep pattern composite score comprising morning chronotype, adequate sleep duration (7-8 h/day), never or rare insomnia, never or rare snoring, and infrequent daytime sleepiness. The overall sleep pattern was categorised into three groups (healthy: ≥ 4; intermediate: 2-3; and poor: ≤ 1 healthy sleep characteristic). Multiple logistic regression analyses were applied to assess associations between DST and sleep with adjustments for potential confounders. Participants with either an intermediate (OR: 1.40; 95% CI: 1.15, 1.71) or a poor (OR: 1.16; 95% CI: 1.10, 1.24) sleep pattern at baseline showed higher odds for high DST at follow-up, compared with those with a healthy baseline sleep pattern. Participants with medium (OR: 1.40; 95% CI: 1.14, 1.71) or high DST (OR: 1.62; 95% CI: 1.30, 2.00) at baseline showed higher odds for poor sleep at follow-up, compared with participants with a low DST. In conclusion, our findings provide consistent evidence that a high DST at baseline is associated with poor sleep over a nearly 7 year follow-up period, and vice versa.

Traditional risk factors for obesity and the metabolic syndrome, such as excess energy intake and lack of physical activity, cannot fully explain the high prevalence of these conditions. Insufficient sleep and circadian misalignment predispose individuals to poor metabolic health and promote weight gain and have received increased research attention in the past 10 years. Insufficient sleep is defined as sleeping less than recommended for health benefits, whereas circadian misalignment is defined as wakefulness and food intake occurring when the internal circadian system is promoting sleep. This Review discusses the impact of insufficient sleep and circadian misalignment in humans on appetite hormones (focusing on ghrelin, leptin and peptide-YY), energy expenditure, food intake and choice, and risk of obesity. Some potential strategies to reduce the adverse effects of sleep disruption on metabolic health are provided and future research priorities are highlighted. Millions of individuals worldwide do not obtain sufficient sleep for healthy metabolic functions. Furthermore, modern working patterns, lifestyles and technologies are often not conducive to adequate sleep at times when the internal physiological clock is promoting it (for example, late-night screen time, shift work and nocturnal social activities). Efforts are needed to highlight the importance of optimal sleep and circadian health in the maintenance of metabolic health and body weight regulation.

BACKGROUND: Cyberbullying victimization has been associated with cannabis use among adolescents. However, it is unclear if this relationship also holds for cyberbullying perpetrators. OBJECTIVE: This cross-sectional study examined the association between cyberbullying involvement and cannabis use among adolescents and tested if parental support was associated with cyberbullying involvement and cannabis use. PARTICIPANTS AND SETTING: Data from 7229 students aged 11-20 years were obtained from the 2019 Ontario Student Drug Use and Health Survey, a province-wide survey of middle and high school students across Ontario, Canada. METHODS: Participants self-reported their cannabis use frequency, their involvement in cyberbullying, and their perception of parental support. Cyberbullying involvement was operationalized as an action taking place at least two times. Multivariable logistic regression models were adjusted for age, sex, ethnoracial background, and subjective socioeconomic status. RESULTS: Overall, 8.6 % of students were cyberbullying victims only, 2 % were cyberbullying perpetrators only, and 2.8 % were both cyberbullying victims and perpetrators. Results showed that experience of cyberbullying victimization only (OR: 2.17; 95 % CI: 1.64-2.88), perpetration only (OR: 2.64; 95 % CI: 1.51-4.63), or both (OR: 3.34; 95 % CI: 2.12-5.28) was associated with greater odds of cannabis use. Results further indicated that higher parental support was associated with lower odds of cannabis use in a dose-response fashion. Higher parental support was also associated with a lower risk of cyberbullying involvement. CONCLUSIONS: These findings suggest that involvement in cyberbullying in any role is associated with greater cannabis use among adolescents and that parental support is associated with less cannabis use and cyberbullying involvement.

Background: Adolescence is often considered a period of heightened stress, and healthy active living behaviors may help those experiencing it to better cope with life stressors and increase their self-esteem. The 24-h movement guidelines for children and adolescents recommend ≥60 min per day of moderate-to-vigorous physical activity, ≤ 2-h per day of recreational screen time, and 9-11-h of sleep per night for school-aged children or 8-10-h per night for adolescents. The objective of this study was to examine the association of meeting the 24-h movement guidelines with life stress and self-esteem among students in Ontario, Canada. Methods: Self-reported data on movement behaviors, life stress and self-esteem were derived from the 2019 cycle of the Ontario Student Drug Use and Health Survey, a cross-sectional and province-wide survey of students in grades 7-12 aged 11 to 20 years (N = 6,932). Multivariable ordered logistic regression analyses were adjusted for the complex sample design of the survey and for important covariates. Results: Overall, meeting all combinations of movement behavior recommendations were associated with lower life stress and better self-esteem compared with meeting none of the recommendations, except meeting the physical activity only or screen time only recommendations that were not associated with lower life stress. Meeting all 3 recommendations was associated with lower life stress (OR: 0.40; 95 CI: 0.30-0.53) and better self-esteem (OR: 0.29; 95% CI: 0.21-0.40). There was a dose-response gradient between the number of recommendations met (3 > 2 > 1) and lower life stress (p < 0.001) and higher self-esteem (p < 0.001), with meeting all 3 recommendations being the best combination. Conclusions: These findings suggest that meeting the recommendations of the 24-h movement guidelines is associated with lower life stress and better self-esteem among adolescents.

BACKGROUND: Little is known about the association between problem technology use in adolescents and school-related outcomes. The purpose of this study was to determine the prevalence of problem technology use and examine its association with academic performance and school connectedness in a sample of students across Ontario, Canada. METHODS: Self-reported data from a sample of 4837 students in grades 9 to 12 (mean age: 15.9 years; 49.5% females) were cross-sectionally analyzed. Ordered logistic regression models were adjusted for important covariates. RESULTS: We found that 35.8% of students used their screen device for at least 5 h a day and about 18.6% had moderate-to-serious symptoms of problem technology use, a prevalence that was higher in females (22.4%) than males (14.9%). Heavy technology use was differentially associated with lower academic performance and lower levels of school connectedness in males and females. Having moderate-to-serious symptoms of problem technology use was associated with lower academic performance among males (AOR = 0.68, 95% CI = 0.53-0.87) and females (AOR = 0.66, 95% CI = 0.52-0.84). It was also associated with less school connectedness in both males (AOR = 0.65, 95% CI = 0.50-0.86) and females (AOR = 0.63, 95% CI = 0.51-0.78). CONCLUSION: Excessive use and problem technology use are highly prevalent among secondary school students, and they are associated with lower academic performance and lower levels of school connectedness.

BACKGROUND: Research has shown that cyberbullying victimization is associated with short sleep duration among adolescents; however, the association between cyberbullying perpetration and sleep duration is unclear. Furthermore, little is known about the factors that could moderate these associations. Thus, the objectives of this study were to investigate the associations of cyberbullying victimization, perpetration, or both with short sleep duration among adolescents, and to test whether age, sex, and adherence to the screen time recommendations (≤2 hours/day) moderate these associations. METHODS: Data on 6834 adolescents aged 11-20 years were derived from a representative cross-sectional study of middle and high school students across Ontario, Canada. Short sleep duration was self-reported and defined as sleeping less than the age-appropriate sleep duration recommendations. Multivariable logistic regression models were adjusted for important covariates. Adjusted odds ratios (AOR) and their 95% confidence intervals (CI) are reported. RESULTS: Cyberbullying victimization (AOR = 1.60, 95% CI = 1.37-1.86), perpetration (AOR = 1.44, 95% CI = 1.16-1.79), or both perpetration and victimization (AOR = 1.71, 95% CI = 1.27-2.30) was associated with greater odds of short sleep duration. Results further indicated that younger students who were not cyberbullied had a lower probability of short sleep duration, but there was no difference in the probability of short sleep duration between being cyberbullied or not among older adolescents. Sex and screen time did not moderate any of the associations between cyberbullying involvement and short sleep duration. CONCLUSION: Involvement in cyberbullying as either a victim, a perpetrator, or both is associated with short sleep duration among adolescents. Strategies that can help to eliminate cyberbullying are needed in public health.

Objectives: Control measures enacted to control the spread of COVID-19 appear to have impacted adolescent movement behaviours. It remains unclear how these changes relate to sociodemographic characteristics and indicators of mental health. Understanding these relationships can contribute to informing health promotion efforts. The purpose of this study is to examine sociodemographic and mental health characteristics associated with changes in movement behaviours (physical activity, screen time, sleep duration) due to the COVID-19 pandemic among adolescents. Methods: This cross-sectional study used May-June 2020 survey data and included 7349 students from Quebec, Ontario, and British Columbia (Canada). ANOVA, χ2 tests, and estimation of effect sizes using Cohen's d and h tests were performed between self-reported perceived changes (increase; decrease; no change) to physical activity, TV watching, social media use, and sleep duration as a result of the COVID-19 pandemic and gender, age, race/ethnicity, income, depression and anxiety symptoms, flourishing-languishing, and self-rated mental health. Results: Over half of students reported increases in TV viewing and social media use and approximately 40% reported decrease in physical activity and increase in sleep duration due to the COVID-19 pandemic. More females (68.9%) than males (54.3%) reported increase in social media use (Cohen's h ≥ 0.2-0.5). No change from pre-COVID-19 social media use and sleep duration were associated with fewer depression and anxiety symptoms and better self-rated mental health compared to reports of an increase or decrease. These effect sizes ranged from small-to-moderate to moderate-to-large (Cohen's d/h ≥ 0.2-0.8). Decreased physical activity and sleep duration were associated with better psychological functioning with effects sizes of small-to-moderate. Compared to an increase or no change, decreased sleep had the largest effect size of less frequent depression symptoms (Cohen's d ≥ 0.5-0.8). Conclusion: Maintaining pre-COVID-19 screen time and sleep duration during early stages of the COVID-19 lockdown was generally beneficial to mental health, with sleep being particularly important in regards to symptoms of depression. Psychological functioning was more related to physical activity and sleep than screen time during the pandemic.
RESUMEN
OBJECTIVE: The Canadian 24-hour movement guidelines for children and youth recommend a minimum of 60 min/day of moderate-to-vigorous physical activity, no more than 2 h/day of recreational screen time, and 8-11 h/night of sleep depending on age. The objective of this study was to examine the associations of meeting combinations of these recommendations with self-rated physical and mental health. METHODS: This study used data from the 2017 (n = 5739) and 2019 (n = 6960) cycles of the Ontario Student Drug Use and Health Survey (OSDUHS), a biennially repeated cross-sectional study of Ontario students in grades 7 through 12. Multivariable ordered logistic regression models were adjusted for age, gender, ethnoracial background, subjective socio-economic status, and body mass index z-scores. RESULTS: Similar patterns were seen in the 2017 and 2019 samples. Compared with meeting none of the recommendations, meeting different combinations of recommendations in the 2019 sample was associated with positive self-rated physical and mental health. A dose-response gradient between the number of recommendations met and self-rated physical (p < 0.001) and mental (p < 0.001) health was observed, with meeting one (AOR: 1.82; 95% CI: 1.58-2.09), two (AOR: 3.54; 95% CI: 2.98-4.22), or three recommendations (AOR: 6.34; 95% CI: 4.46-9.02) being increasingly associated with positive self-rated physical health compared with meeting none; and meeting one (AOR: 1.51; 95% CI: 1.33-1.71), two (AOR: 2.70; 95% CI: 2.31-3.17), or three recommendations (AOR: 3.58; 95% CI: 2.57-4.98) being increasingly associated with positive self-rated mental health compared with meeting none. CONCLUSION: Meeting the 24-hour movement guidelines is associated with better self-rated physical and mental health among adolescents.
RéSUMé: OBJECTIF: Les Directives canadiennes en matière de mouvement sur 24 heures pour les enfants et les jeunes recommandent un minimum de 60 min par jour d'activité physique d'intensité moyenne à élevée, un maximum de 2 heures par jour de temps de loisir devant un écran et de 8 à 11 heures de sommeil selon l'âge. L'objectif de cette étude était d'examiner les associations entre l'adoption d'une combinaison de ces recommandations et l'autoévaluation de la santé physique et mentale. MéTHODE: Cette étude s'est appuyée sur les données tirées des cycles de 2017 (n = 5 739) et de 2019 (n = 6 960) du Sondage sur la consommation de drogues et la santé des élèves de l'Ontario (SCDSEO), un sondage transversal réalisé tous les deux ans auprès d'élèves de la 7e à la 12e année en Ontario. Les modèles de régression logistique multivariés ont été ajustés en ce qui a trait à l'âge, au genre, aux antécédents ethnoraciaux, au statut socioéconomique subjectif et aux scores-z de l'indice de masse corporelle. RéSULTATS: Des tendances similaires ont été observées dans les échantillons de 2017 et de 2019. L'adoption d'une combinaison des recommandations parmi l'échantillon de 2019, comparativement au fait de ne se conformer à aucune d'elles, était associée à une autoévaluation positive de la santé physique et mentale. Un gradient dose-réponse entre le nombre de recommandations adoptées et l'autoévaluation de la santé physique (p < 0,001) et mentale (p < 0,001) a été observé. L'adoption d'une (RCa : 1,82; IC de 95% : 1,58 à 2,09), de deux (RCa : 3,54; IC de 95% : 2,98 à 4,22) ou de trois recommandations (RCa : 6,34; IC de 95% : 4,46 à 9,02) était étroitement associée à une autoévaluation positive de la santé physique, comparativement au fait de ne se conformer à aucune d'elles; et l'adoption d'une (RCa : 1,51; IC de 95% : 1,33 à 1,71), de deux (RCa : 2,70; IC de 95% : 2,31 à 3,17) ou de trois recommandations (RCa : 3,58; IC de 95% : 2,57 à 4,98) était étroitement associée à une autoévaluation positive de la santé mentale, comparativement au fait de ne se conformer à aucune d'elles. CONCLUSION: La conformité aux directives en matière de mouvement sur 24 heures est associée à une meilleure autoévaluation de la santé physique et mentale chez les adolescents.

BACKGROUND: Research examining the associations between movement behaviours and mental health indicators within a compositional framework are sparse and limited by their cross-sectional study design. This study has three objectives. First, to describe the change in movement behaviour composition over time. Second, to explore the association between change in movement behaviour composition and change in depressive symptoms. Third, to explore how reallocations of time between movement behaviours are associated with changes in depressive symptoms. METHODS: Longitudinal data of 14,620 students in grades 9-12 (mean age: 14.9 years) attending secondary schools in Canada (Ontario, British Columbia, Alberta, Quebec) were obtained from two waves (2017/18, 2018/19) of the COMPASS study. Moderate-to-vigorous physical activity (MVPA), recreational screen time, and sleep duration were self-reported. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (Revised)-10 (CESD-R-10). Compositional data analyses using pivot coordinates and compositional isotemporal substitution for longitudinal data were used to analyse the data. Analyses accounted for school clustering, were stratified by gender and age (< or ≥ 15 years), and were adjusted for race/ethnicity, body mass index z-score, baseline movement behaviour composition, and baseline depressive symptoms. RESULTS: There were significant differences in movement behaviour composition over time across all subgroups. For example, the relative contributions of MVPA and sleep duration to the movement behaviour composition decreased over time while screen time increased among younger boys and girls and older girls. Increasing sleep duration relative to the remaining behaviours (i.e. screen time and MVPA) was associated with lower depressive symptoms among all subgroups. Increasing screen time relative to the remaining behaviours (i.e. MVPA and sleep duration) was associated with higher depressive symptoms among all subgroups. Increasing MVPA relative to the remaining behaviours (i.e. screen time and sleep duration) was associated with lower depressive symptoms in older girls only. Isotemporal substitution estimates indicated that decreasing screen time by 60 minutes/day and replacing that time with 60 minutes of additional sleep is associated with the largest change in depressive symptoms across all subgroups. CONCLUSIONS: Findings from this prospective analysis suggest that increased sleep duration and reduced screen time are important determinants of lower depressive symptoms among adolescents.

Background: Alcohol consumption and distress have increased among Canadians since the start of the COVID-19 pandemic. Methods: We examined whether sociodemographic and COVID-19-related worries are associated with various combinations of alcohol consumption and comorbid psychological distress variables among a Canadian sample of adults. Data were derived from a sample of Canadian adults (N = 1,005, 49.6% female) who participated in an online survey in May 2020. Four multivariate ordinal logistic regression models were used to estimate the odds of binge drinking, increased alcohol consumption during the pandemic, and psychological distress. Predictor variables used in the analyses included self-reported sociodemographic characteristics, financial worries, COVID-19 impact on work, and worrying about getting ill. Results: Women were found to have higher odds of increased drinking and anxiety. Also being divorced, separated, or widowed was associated with higher odds of binge drinking and anxiety, and binge drinking and depression. Furthermore, being 60 or older was associated with lower odds of binge drinking and depression and increased drinking and depression, as well as lower odds of increased drinking and depression and increased drinking and anxiety. High income groups were associated with higher odds of binge drinking, increased drinking, and mental distress. Compared to those less worried, being very worried about finances were associated with higher odds of binge drinking and anxiety, increased drinking and anxiety, and increased drinking and depression. Also, being very worried about getting ill with COVID was associated with higher odds of binge drinking and anxiety and increased drinking and anxiety. Conclusion: Our findings identify several demographic and COVID-related worries for increased odds of alcohol intake and co-morbid psychological distress during the COVID-19 pandemic, including identifying as a woman, high income groups, being divorced, separated or widowed, and experiencing financial worries and COVID illness worries. These characteristics should be considered when developing prevention and treatment programs for adults with problematic alcohol use and comorbid anxiety and depression.
