| Title: | Associations between social jetlag trajectories and body mass index among young adults |

| Abstract: | STUDY OBJECTIVES: This study employed longitudinal data collected repeatedly from individuals over the course of several years to examine the trajectories of social jetlag from ages 11 to 22 years and their associations with subsequent BMI. Potential sex differences were also investigated. METHODS: Data were obtained from 2 longitudinal studies conducted in Taiwan (N = 4287). Social jetlag was defined as ≥2 h of absolute difference in sleep midpoint between weekdays and weekends. BMI was calculated using weight (kg)/height(m)2 and categorized as underweight (<18 kg/m2), normal weight (18 kg/m2 ≤ BMI < 24 kg/m2), overweight (24 kg/m2 ≤ BMI < 27 kg/m2), and obese (≥27 kg/m2). Group-based trajectory modeling and multinomial logistic regression were applied to investigate study objectives. RESULTS: Four distinct trajectories of social jetlag throughout the adolescent years were identified, with corresponding proportions as follows: low-stable (42%), moderate-decreasing (19%), low-increasing (22%), and chronic (17%) trajectories. Among males, the risk of being underweight (aOR, 1.96; 95% CI, 1.35-2.84) or obese (aOR, 1.40; 95% CI, 1.02-1.92) was higher in individuals with a low-increasing trajectory than in those with a low-stable trajectory. Among females, those with a low-increasing (aOR, 1.61; 95% CI, 1.02-2.54) or chronic (aOR, 2.04; 95% CI, 1.27-3.25) trajectory were at a higher risk of being obese relative to those with a low-stable trajectory. CONCLUSION: Addressing the development of increasing or chronic social jetlag during adolescence can help prevent abnormal BMI in young adulthood. Practitioners should consider sex differences in treatment or consultation. |
