The association between cigarette smoking and sleep deprivation among adolescents in Gulf Cooperation Council countries: analysis of national surveys

OBJECTIVES

To examine the association between sleep deprivation and cigarette smoking among adolescents in the "Gulf Cooperation Council (GCC)" countries, accounting for relevant sociodemographic and behavioral factors.

METHODS

The present study was conducted between June and August 2024 using data from the most recent "Global School-based Student Health Survey (GSHS)" conducted in 5 GCC countries. The study included 21,105 adolescents aged 11-18 years. Multiple logistic regression models were used to examine the association in each country. A random-effects meta-analysis was conducted to synthesize results across countries.

RESULTS

Overall, 17.9% of adolescents reported sleep deprivation. The pooled adjusted odds ratio for the association between cigarette smoking and sleep deprivation was 1.75 (95% CI: 1.56-1.96), indicating that adolescents who smoked cigarettes had 75% higher odds of experiencing sleep deprivation compared to non-smokers. This association was consistent across all 5 GCC countries, with low heterogeneity (I² = 18.1%).

CONCLUSION

This study provides evidence of a significant positive association between sleep deprivation and cigarette smoking among adolescents in GCC countries. These findings emphasize the need for comprehensive public health interventions promoting both smoking prevention and sleep health among adolescents in the region.

Within-person reciprocal links between stress, sleep, and depressive symptoms across Latino/a adolescents' transition to and through college

Evidence suggests bidirectional relations between stress, sleep, and depressive symptoms in adolescence and young adulthood. Less research has disaggregated within- and between-person variance in these associations over time or within Latino/a college students. This study examined longitudinal, within-person reciprocal relations between stress, sleep, and depressive symptoms among 181 Latino/a adolescents (M age = 18.10; SD = 0.41, 35% male) transitioning to college. Participants were assessed in their senior year of high school and annually until their fourth year of college. A random intercept cross-lagged panel model (RI-CLPM) was used to parse out within- and between-person sources of variance. Results indicated overall (between-person) relations among depressive symptoms and school/college stress and sleep problems. There were reciprocal within-person links between stress and sleep problems across the first two years of college. Within-person increases in depressive symptoms during the second year of college predicted more stress than usual in the third year, which predicted increased depressive symptoms in the fourth year. More sleep problems than usual in the third year of college predicted higher stress in the fourth year. Findings provide evidence for within-person cross-lagged relations among various domains of adjustment during college and may inform future prevention efforts for incoming Latino/a college students targeting mental health and sleep problems.

Negative Affect, Sensation Seeking, and Adolescent Substance Use Development: The Moderating Role of Executive Function

It is unknown how the Addictions Neuroclinical Assessment markers-negative affect, sensation seeking, and executive function-contribute to substance use development. This study examined whether associations of negative affect and sensation seeking with substance use vary by executive function. Participants were 167 adolescents (47% female) who participated annually for four years (Mage = 14.07, SDage = 0.54 at Time 1). There were within-person bidirectional associations between higher negative affect and higher substance use for adolescents with lower executive function. Adolescents with higher sensation seeking at age 14 exhibited increasing substance use trajectories from age 14 to 17, regardless of executive function level. Negative affect and substance use influence each other within individuals, whereas sensation seeking predicts substance use between individuals.
