P10-026 - Gender, stressful life events, sleep and obesity: a prospective study of young people in a British Columbia cohort

Monday, Jun 11
8:00 AM – 3:00 PM

Objective: To investigate the gender-specific association between stressful life events and subsequent obesity and, secondarily, the potential effect modification by sleep deprivation.

Methods: Prospective study using population-based cohort data on self-reported obesity, stressful life events, sleep deprivation and covariables in adolescents aged 13-17 (n=916). Data were analysed by multivariable logistic regression, with interaction terms, and postestimation calculation of adjusted mean prevalence.

Results: Young men reporting multiple life events were more than twice as likely of developing obesity at 6-month follow-up (OR 2.74 [CI95: 1.09, 6.89]), compared to those reporting no events. Although more females than males reported multiple stressful life events, we found no association with obesity in young women. We also found a more pronounced association between stressful events and obesity among those reporting being sleep deprived (versus not deprived), particularly for young men.

Conclusion: Findings highlight the importance of taking a gender perspective when studying the development of obesity in adolescence, as well as the need for more robust longitudinal studies looking at stressful life events and obesity in adolescence.

Funding Source: This research was partly funded by the UBC Work Learn Program for undergraduate students.
