Maturational development, physical activity, and sleep quality in adolescent girls: DADOS project

Abstract

Sleep and physical activity (PA) are fundamental behaviors for adolescents’ health since they are related to optimal physical, cognitive, and emotional development. The aim of our study was to analyze the influence of the maturational development on sleep quality in adolescent girls, as well as to evaluate the daily PA level based on the level of maturational development. The level of maturational development of 129 girls participating in the DADOS project was assessed through the Tanner scale. Two groups were created (Tanner <4 and Tanner ≥4). Sleep quality was assessed using the Spanish version of the Pittsburgh Sleep Quality Index (PSQI), based on which the following groups were created: optimal (PSQI ≤ 5) and poor (PSQI >5) sleep quality. PA was measured with triaxial accelerometers. Body mass index (BMI, kg/m2) was included in the study as a covariable. No significant differences were found in the total PSQI score between the maturational development groups (p >.05). Adolescents with higher maturational development performed less PA (p.05). Girls with higher maturational development (Tanner e»4) did not show increased risk of poor sleep quality (OR=1.08, 95%CI 0.51-2.34), considering their BMI and daily PA. In conclusion, the maturational development of adolescent girls does not seem to be related with sleep quality but it influences the PA levels.
