Overweight/obesity in students associated with short sleep duration which can be improved by nanocapsules

Abstract

This study was designed to investigate the prevalence of short sleep duration in adolescents from middle school in Fuzhou, China and explore the association between short sleep duration and overweight/obesity. Nano-encapsulated vitamin D3 can improve sleep deprivation, thus reducing the prevalence of overweight and obesity. A total of 13063 students (male: 6,500; female: 6,553) from 18 schools were investigated in the study. Questionnaires focusing on short sleep duration and overweight or obesity related factors were collected. The subjects reported their own sleep duration. The body weight and height of each subject were measured by the qualified personnel. Logistic regression analysis was used to evaluate the effects of short sleep duration on overweight/obesity in school students. The rates of overweight and obesity were 12.1% and 7.1%, respectively. The prevalence of short sleep duration among teenagers was 82.8%. The majority of high school students (92.5%) suffered from short sleep duration. Compared with male children with a sleep duration of 8-10 h per day, the odds ratios (95% Cl) of overweight/obesity for those with a sleep duration of less than 6 h or 6-8 h, were 1.63 (1.25-2.13) and 1.06 (0.88-1.27), respectively, after adjusting social and demographic status, mental health and lifestyle factors, while for female children, the odds ratios were 1.38 (0.99-1.93) and 1.04 (0.79-1.35), respectively. A large number of adolescents suffered from short sleep duration. Short sleep duration is associated with higher odds of overweight/obesity in male children.
