Impact of short sleep on metabolic variables in obese children with obstructive sleep apnea

Objectives/Hypothesis

To analyze the association between sleep duration, metabolic variables, and insulin resistance in obese children with and without obstructive sleep apnea. The decline in sleep duration has paralleled a dramatic increase in the prevalence of obesity and diabetes, suggesting a mechanistic relationship.

Study Design

Retrospective, case series.

Methods

Consecutive obese patients 3 to 12 years of age who underwent polysomnography (PSG) and a metabolic panel and who completed a 14-item sleep questionnaire were analyzed. All laboratory testing was conducted within 3 months of PSG. Total sleep times were obtained from the PSG and confirmed by the questionnaire.

Results

A total of 171 patients (55.0% male) were studied. All patients were obese (body mass index [BMI] z score > 95th percentile). Patients were categorized into three groups: short sleepers, borderline sleepers, and optimal sleepers. Eighty-six (50.3%) patients were short sleepers, 71 (41.5%) were borderline sleepers, and 14 (8.2%) were optimal sleepers. The mean BMI z score was 3.13 ± 1.3 in short sleepers, 3.3 ± 1.1 in borderline sleepers, and 3.5 ± 1.5 in optimal sleepers (P = .39). There was no statistical difference in high- and low-density lipoprotein levels (P = .21 and P = .76, respectively) and total cholesterol (P = .43) among subgroups. Triglycerides, blood glucose, insulin, and homeostasis model assessment–insulin resistance were significantly higher in short sleepers when compared to borderline or normal sleepers (P = .008, P < .001, P < .001, and P < .001, respectively).

Conclusions

Short sleep duration was correlated with alterations in metabolic variables and insulin resistance in obese patients. This raises concern for development of comorbid conditions that can persist into adulthood.
