The correlation between sleep quality and the prevalence of obesity in school-age children.

Background: The prevalence of obesity increases year by year. Sleep quality is considered to be one of the obesity causes. The current average sleep range of children in Indonesia was 6-7 hours. This study aims to analyze whether sleep quality affects the prevalence of obesity in children.

Design And Methods: This study used a prospective cohort as the research method. The samples consisted of 37 primary school-age children (4th-6th grade) from West Java and Sumatra, which were selected using the snowball sampling technique. The data were collected by using PSQI and sleep logs (within a month).

Result: The statistical results showed that most of the obese children, 12 out of 19, had poor sleep quality (63.2%), while most of the non-obese children (normal),15 out of 18, had good sleep quality (83.3%). Based on the chi-square statistic, the p-value =0.011
Conclusions: This study found there were correlations between dietary intake, physical activity, sleep quality, and obesity in school-age children. The most dominant factor related to obesity in school-age children is the habitual sleep efficiency (OR=12.354).
