Short sleep duration associated with obesity in children

These Chinese investigators studied the association between sleep duration and risk of hyperglycemia among preschool children in a population-based cross-sectional study including 619 obese and 617 age-matched nonobese children from 71 randomly selected kindergartens.

They found: “Obese children were more likely to have shorter sleep duration (8 hours) compared with their nonobese counterparts. Compared with those who slept for 9 or 10 hours per night, those who slept for 8 hours or less had a significantly higher likelihood of having hyperglycemia, controlling for age and sex (OR 1.65). After further adjustment for other potential confounders, the association still remained statistically significant (OR 1.64). In the stratified multivariable analyses, those who were obese and slept for 8 hours or less had an increased risk of having hyperglycemia (OR 2.12) compared with those who were nonobese and slept for 9 hours or more.”

The authors concluded: “Shorter sleep duration is associated with an increased risk of having hyperglycemia among preschool Chinese children. Whether adequate sleep may help maintain euglycemia among children, especially for those who are overweight or obese, warrants further investigation.”

Causality can’t be determined by this study design so we will have to wait further research.
