Introduction:
Changes in sleep quality and quantity occur in adolescence and can lead to the compensatory behavior of daytime napping.
Objective:
Analyze factors related to napping in adolescents.
Methods:
A population-based cross-sectional study was conducted with 1022 adolescents who participated in the 2014-2015 Health Survey of the city of Campinas, state of São Paulo, Brazil. Napping was the dependent variable. Sociodemographic characteristics, living habits, health-related behaviors, feelings of loneliness, satisfaction with life and nocturnal sleep habits were the independent variables. Data analysis was performed using Rao-Scott chi-square test, unpaired Student's t-test and Poisson regression analysis; p < 0.05 was considered significant. The software STATA was used for analysis.
Results:
Mean participant age was 14.6 years (SD: 2.7; range: 10 to 19 years). Males accounted for 50.9% of the sample and 55.7% had white skin color. A total of 40.5% reported napping. Napping was more common in females (p = 0.006), the 14-to-17-year-old age group (p = 0.002), those who took medications in the previous 15 days (p = 0.001), those who were insufficiently active (p = 0.036), those who reported little or no satisfaction with life (p = 0.008) and those who woke up in bad mood (p = 0.004). Adolescents who napped also reported shorter sleep during the week (p < 0.001) and a perceived greater need for sleep (p < 0.001).
Conclusion:
The prevalence of napping among the adolescents was independently associated with shorter average sleep, a perceived greater need for sleep than that obtained and waking up in a bad mood.
