FACTORS ASSOCIATED WITH UNINTENTIONAL NAPPING IN ADOLESCENTS: POPULATION BASED STUDY
Introduction: Adolescents present changes in sleep patterns, such as difficulty in sleeping and getting up early, which is frequently imposed on them by school and social commitments. This may result in sleep deprivation and poor sleep quality. Naps can be a compensatory response to sleep deprivation, especially when unintentional, and may be associated with factors that are detrimental to adolescent health.
Objective: To analyze factors associated with unintentional napping in adolescents.
Methods: population-based cross-sectional study conducted with data from the Campinas Municipal Health Survey (Inquérito de Saúde do Município de Campinas - ISACamp)-2014/2015, with participants from 10 to 19 years of age (n=1022), approved by the institution’s Research Ethics Committee. Dependent variable was the intentionality of naps and independent variables were: sociodemographic characteristics, feelings of loneliness, life and health habits and sleep habits. Descriptive analysis, Rao-Scott chi-square test and Student’s t-test were performed, considering a significance level of 5%. The Stata 14.0 software was used in survey mode for analysis.
Results: 50.9% were male and 84.0% were students; mean age was 14.6 (SD=2.7) years. Prevalence of unintentional napping was 8.2%, and was significantly lower in white adolescents (p=0.003), in those who often or always felt isolated (p=0.001) and that never felt well disposed after awakening (p<0.0001). There was no significant difference in habits such as physical activity and alcohol consumption. Duration of sleep on weekdays was 437 (SD=191) minutes and on weekends, 541 (SD=117) minutes, with no significant difference from those who napped intentionally. Adolescents that napped unintentionally estimated that they needed a mean of 530 (SD=204) minutes of sleep to feel well disposed after awakening.
Conclusions: Adolescents that napped unintentionally verbalized the need to sleep for longer periods, suggesting that they are sleep-deprived. They expressed unwillingness to wake up and feelings of isolation. Identifying the reasons related to napping can contribute to promote better sleep quality in this age group, as well as generate actions to improve health and even public policies, involving healthcare providers, educators and family members, in order to avoid damage to physical and psychological health of the adolescent.
