The study involved 619 obese and 617 nonobese children aged 3 to 6 years from 71 randomly selected kindergartens in Tianjin, China. About 47% of the obese children and 37% of the nonobese children averaged 8 or fewer hours of sleep per night; such children had a significantly higher likelihood of hyperglycemia (defined as a fasting glucose of 100 mg/dL or higher) than those who slept for 9 or 10 hours nightly (odds ratio of 1.65), even after adjustment for potential confounders. The risk of hyperglycemia was even greater among those who were obese and slept 8 hours or less compared with children who were nonobese and slept at least 9 hours (odds ratio of 2.12).
