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 <a (0.05) indicating that H0 was rejected, which means there was a correlation between sleep quality and obesity, with OR=8.571 (95% CI: 1.818-40.423), which means the children with poor sleep quality were likely to experience obesity 8.6 times greater than those who had good sleep quality.

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).
