INTRODUCTION:
Sleep modulates neuroendocrine function and metabolism; therefore, changes in sleep duration may lead to developing obesity during adolescence.OBJECTIVE:
To assess the possible association among nocturnal sleep duration, the presence of overweight and metabolic alterations in a group of adolescents. POPULATION ANDMETHODS:
Cross-sectional, analytical study conducted at a school in Valencia, Venezuela, during the 2012-2013 school year. Participants were 12 to 17 year-old adolescents. A survey on nocturnal sleep duration was administered; weight, height and waist circumference were recorded; and glycemia, lipid profile and insulinemia levels were measured. Body mass index and the homeostasis model assessment of insulin resistance (HOMA-IR) index were calculated.RESULTS:
Ninety adolescents were included. Compared to the group with normal weight, adolescents with excessive weight had, in average, fewer sleep hours Sundays through Thursdays (p < 0.05) and a higher rate of sleep deficit and sleep debt (p < 0.05). Low HDL cholesterol and insulin resistance was significantly associated with sleep debt (p < 0.05). Among adolescents with sleep debt, the risk of having excess weight was 2.70 times higher (95
