Introduction: Sleep is an important brain function, and its pattern undergoes important changes from childhood to adolescence, marked by a progressive delay in the sleep phase at the beginning of puberty. Sleep deprivation hampers cognition, alertness and memory, mood disorders and metabolic implications. Objective: To investigate the association between sleep patterns, nutritional status and cardiometabolic risk in adolescents. Materials and method: This was a cross-sectional study involving 339 adolescents from the municipal schools of Santana de Parnaíba, aged between 12 and 15 years. Anthropometric measurements such as weight, height, waist and neck circumference and sexual maturation were measured. The daytime sleepiness scale was used, as well as the Munich chronotype and social jetlag questionnaires. Results: The score on the Pediatric Daytime Sleepiness Scale (PDSS) in girls and boys was 16.06 and 13.81, respectively. According to the classification of hours of sleep, there was no difference in body mass index, waist and neck circumference. More hours of sleep were observed during weekends, regardless of nutritional status. The regression analysis showed that male gender and physical activity were protective factors against daytime sleepiness; in contrast, the older the age, the chronotype and social jetlag, the greater the daytime sleepiness. Male gender, post-pubertal, high neck circumference, overweight and higher PDSS score were positively associated with cardiovascular risk, whereas the social jetlag played a protective factor against this risk. Conclusion: Insufficient sleep in adolescents generated daytime sleepiness and social jetlag. The latter had a protective effect against cardiometabolic diseases.
