Abstract

Introduction: Obesity and the metabolic syndrome are rapidly increasing in developing countries. Whether the metabolic syndrome is independently associated with obstructive sleep apnea (OSA) is not clear. Objective: This study investigated the association between OSA and the metabolic syndrome in obese Asian Indians. Methods: We studied 240 obese subjects [body mass index (BMI) >25 kg/m2], 121 with OSA and 119 without OSA, matched for age, BMI, and percentage body fat (%BF). Full-montage digital polysomnography, fasting blood glucose (FBG), lipid levels, and blood pressure (BP) were done in all subjects. Results: Subjects with OSA showed higher prevalence of the metabolic syndrome as compared to subjects without OSA [67.8% vs. 42.02%; χ2=16.08, P<0.0001, odds ratio (OR)=2.90, 95% confidence interval (CI)]. Prevalence of the metabolic syndrome was significantly higher in the severe OSA group as compared to the moderate OSA group (78.7% vs. 40.9%; χ2=11.57; P<0.001; OR=0.19, 95% CI). Fasting insulin levels were significantly higher in subjects with OSA as compared to subjects without OSA [median (range); 84.03(12.5-541.7) pmol/L vs. 64.4(10.4-520.8) pmol/L; P=0.002)]. Regression analysis suggested that OSA was independently and positively associated with the metabolic syndrome, male gender, and fasting insulin levels. Conclusion: OSA is independently associated with the metabolic syndrome in Asian Indians in northern India.
