Comportamentos associados ao sono em estudantes do ensino médio: análises transversal e prospectiva

Abstract

LicenceAbstract -The association between health behaviors and sleep patterns in youths has been tested using cross-sectional data, and prospective evidence is needed. The aim of this study was to investigate the cross-sectional and prospective associations between behavioral variables and sleep quality and duration. A secondary analysis was conducted using data that were collected in March and December 2006 from a random sample of high school students (aged 14-24 years) from Recife and Florianopolis, Brazil, for the "Saúde na Boa" intervention. Data on the perception of sleep quality and duration and lifestyle variables were obtained through self-reported questionnaires. Data were analyzed using crude and adjusted binary logistic regressions. The percentages of students reporting poor sleep quality and insufficient sleep duration were 45.7% and 76.7%, respectively, considering the cross-sectional data, and 45.8% and 77.5%, respectively, considering the longitudinal data. There was a cross-sectional association between lower physical activity (OR = 0.74, 95% CI: 0.55, 0.99) and higher snack consumption (OR = 1.67, 95% CI: 1.18, 2.36) and negative sleep quality. Excessive TV watching (OR = 0.48, 95% CI: 0.30, 0.75) and higher levels of soft drink consumption (OR = 1.84, 95% CI: 1.19, 2.84) were associated with insufficient sleep duration. However, no behavioral variables were associated with sleep quality and duration in the prospective analysis. The prevalence of self-reported poor sleep quality and duration were similar in the cross-sectional and longitudinal analyses. Some behaviors were associated with sleep patterns in the cross-sectional analyses, but these findings were not confirmed in the prospective analyses.

(OR = 0,74; IC 95%: 0,55; 0,99) e o maior consumo de salgados (OR = 1,67; IC 95%: 1,18;2,36) estiveram associados à qualidade negativa do sono, enquanto o tempo excessivo de televisão (OR = 0,48; IC 95%: 0,30; 0,75) Resumo -A associação entre comportamentos de saúde e sono tem sido testada em jovens com dados transversais, mas evidências prospectivas são necessárias. O objetivo do estudo foi verificar associações transversais e prospectivas entre variáveis comportamentais e percepções

Association between the Degree of Processing of Consumed Foods and Sleep Quality in Adolescents

“…In relation to the sleep quality of the evaluated adolescents, we found that most had poor sleep quality. This finding is similar to that of Hoefelmann et al [31] who found 45.7% of 14-24-year-olds had poor sleep quality. Explanations for this high prevalence may be related to biological, social, and behavioral factors such as age, economic class, physical inactivity, screen time, school activities, caffeine intake, and chronic diseases [9,10,[32][33][34][35].Despite the considerable coffee consumption among the studied adolescents and evidence that high and moderate caffeine consumption is associated with sleep disorders in adolescents [36,37], there was no significant difference in coffee consumption between the groups of good and poor sleepers.…”

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

“…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.…”

“…There has been an increasing interest in investigating sleep patterns in adolescents. [1][2][3][4] This may be due to the fact that biopsychosocial, cognitive and behavioral changes in this phase of life can negatively influence the duration and quality of one's sleep. 5 Inadequate sleep can produce health problems, such as poor school performance, 6 inadequate eating habits, 2 cardiometabolic risk markers, 7 obesity and insulin resistance.…”

“…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.…”

“…Such studies measured specific sedentary behaviors, 16 and did not consider simultaneous exposure to physical inactivity, excessive screen time and being overweight. [2][3][4]10 Analyzes involving the possible associations of simultaneous exposure to these factors can contribute to a better understanding of the possible influences of these factors on the duration and perception of sleep quality in adolescents. Thus, this study determined the prevalence of negative perception of sleep quality and short sleep duration and analyzed whether physical inactivity, excessive screen time and being overweight are associated with these outcomes in adolescents.…”
