Abstract

This study investigates the relationship between social jetlag and obesity-related outcomes in Spanish adolescents, utilizing cross-sectional data from the EHDLA (Estudio de Hábitos de Dieta y Actividad en la Adolescencia) study. Social jetlag, defined as the misalignment between an individual’s internal biological clock and their social schedule, is known to disrupt sleep patterns and may impact health. The analysis explores how social jetlag correlates with obesity indicators, such as body mass index (BMI) and waist circumference, among teenagers. Results from the EHDLA study reveal significant associations between social jetlag and increased obesity risk, highlighting the potential impact of irregular sleep schedules on adolescent health. The findings underscore the importance of addressing sleep patterns and social schedules in obesity prevention and intervention strategies for this age group.
