Sleep duration and overweight: is there a relationship in adolescence?

Abstract

Objective: This study aimed to investigate the association between sleep duration and excess weight in Brazilian adolescents. Methods: This is a cross-sectional study conducted with 65,837 adolescents, aged 12 to 17 years, enrolled in the Study of Cardiovascular Risks in Adolescents (ERICA). Sleep duration was assessed by means of a questionnaire focusing on weekday and weekend hours of sleep. Nutritional status was assessed based on body mass index, and participants were classified according to age and gender. The statistical analysis was performed with the Stata 13 software, using the survey command. Poisson regression was used to determine the association of excess weight with sleep duration categories. Results: A decline in sleep duration was associated with advancing age. The prevalence of short and long-term sleep among adolescents was 17.9 and 3.6%, respectively, while overweight was diagnosed in 25.5% of the sample. Adolescents who reported having short sleep had 10% (PR = 1.10; 95%CI 1.06 – 1.15) more overweight, while those who reported sleeping more than 11 hours had approximately 12% (PR = 0.88; 95%CI 0.78 – 0.99) less excess weight. Conclusion: Our findings reinforce the assumption that insufficient sleep poses health risks, and encouraging regular and sufficient sleep may be a cost-effective intervention for the prevention of overweight in adolescence.

Sleep Hygiene Intervention Improves Sleep Time and Duration in High School Students

“…Therefore, the guidance was effective from this perspective. The current study, in conformity with others, 30,32,34,35 shows that sleep compensation during the weekends is a relevant factor and requires guidance to prevent adolescents from delaying sleep time on school days.…”

“…This variable was controlled due to the possibility of influencing sleep parameters, such as the amount of sleep hours per day. 30,31 Adolescents should sleep between 8.5 and 10.5 hours a day to support their metabolism and other biological functions, which may be altered by sleep deprivation. 32 The students' Portuguese and mathematics marks were higher before the intervention, which may be related to the Table 3 Correlations regarding the use of technologies, insomnia and sleepiness pre-and postintervention through the STRICT, ISI, ans PDSS instruments.…”

“…On the contrary, other studies have shown that lack of sleep duration could increase a person's risk of being overweight and obese 33 . Another study showed that adolescents with short sleep duration had a 1.1 times greater risk of being overweight than adolescents with long sleep duration (> 11 hours/day) 34 .…”

“…Para el presente estudio, la muestra analítica fue de n= 99 estudiantes, los cuales fueron seleccionados mediante un muestreo no probabilístico por conveniencia. Los criterios de inclusión fueron ser alumno inscrito durante el periodo 2023-1 en cualquiera de los ocho semestres, se excluyeron participantes con algún padecimiento neurodegenerativo y se eliminaron aquellos registros incompletos o con valores extremos en la cantidad de horas de sueño por noche (≤4 horas o ≥12 horas) (n= 5) (Corrêa, de Souza Borges, & Araújo de Oliveira, 2021).…”
