A baixa duração do sono está associada com a inatividade física em adolescentes amazonenses?

Abstract

ResumoEste estudo teve como objetivo analisar os fatores associados à baixa duração do sono em adolescentes Amazonenses. Trata--se de um estudo epidemiológico transversal, conduzido com 2517 adolescentes (1106 do sexo masculino e 1411 do sexo feminino), com idades de 14 a 19 anos, matriculados em escolas públicas de ensino médio no estado do Amazonas. Além da baixa duração do sono (< oito horas/dia) foram investigadas informações sobre sexo, faixa etária, ano escolar, turno escolar, renda familiar, situação ocupacional e atividade físi-ca. Associações entre a baixa duração de sono com as demais variáveis foram analisadas por meio da regressão de Poisson. A prevalência de baixa duração de sono foi de (51,2%; IC95%: 49,2-52,9). Adolescentes mais velhos de 18 a 19 anos (RP= 1,14; IC95%: 1,01-1,29), que estudam no turno matutino (RP= 1,37; IC95%: 1,25-1,48) e noturno (RP= 1,16; IC95%: 1,04-1,28), os que trabalham (RP= 1,34; IC95%: 1,23-1,45) e são inativos fisicamente (RP=1,27; IC95%: 1,06-1,53) apresentaram maior risco para a baixa duração do sono. Os resultados mostram que fatores biológicos, comportamentais e ambientais são fatores importantes para a duração do sono dos adolescentes. Palavras-chave

Physical Activity, Screen Time, Nutritional Status and Sleep in Adolescents in Northeast Brazil

“…Table 2 Crude and adjusted logistic regression analysis for association between physical activity level, screen time and nutritional status with short sleep duration and negative perception of sleep quality in adolescents, João Pessoa, Paraíba, 2014. and Northern Brazil (Amazonas -51.2%). 14 The proportion of negative perception of sleep quality in the present study was also lower than that of foreign countries 12,25 and other Brazilian regions. 1,15 A probable explanation for this variability in the results is the fact that adolescent sleep is influenced by socioeconomic, cultural and behavioral differences, which seem to be decisive in altering the duration and quality of sleep in adolescents.…”

“…1,15 A probable explanation for this variability in the results is the fact that adolescent sleep is influenced by socioeconomic, cultural and behavioral differences, which seem to be decisive in altering the duration and quality of sleep in adolescents. 2,14 Differences in sample characteristics should also be considered, since, in this study, about 60% of adolescents were aged up to 11 years old. This was different from the other studies in which the age range age ranged from 14 to 19 years old.…”

“…This was different from the other studies in which the age range age ranged from 14 to 19 years old. 2,10,14,15,26 Older teenagers have more freedom to manage their time with friends, participate in leisure activities until late hours, and socialize more frequently and for longer on electronic devices, 17 which can contribute to inadequate sleep.…”

“…2 Low levels of physical activity, 3 excessive screen time (television, video games and computer) 2,4 and being overweight 13 are associated with negative perception and not enough sleep in adolescents. However, most of these studies were with older adolescents (14-19 years old), 2,[14][15][16] that have social and behavioral characteristics that are different from younger ones, 17 in unrepresentative samples. Such studies measured specific sedentary behaviors, 16 and did not consider simultaneous exposure to physical inactivity, excessive screen time and being overweight.…”
