Objectives: To correlate body habitus with severity of obstructive sleep apnea (OSA) in Indian subjects. Subjects: Prospective study. Consecutive patients with OSA during the period 2013 to 2016 were included. Materials and methods: Body mass index (BMI), neck circumference (NC), and Epworth sleepiness scale (ESS) were recorded and their association with severity of OSA as graded by apnea-hypopnea index (AHI) was analyzed Results: Totally 100 patients were included; 91 were male. Mean age was 46.58 ± 12.92 years. Abnormal BMI, NC, and ESS were observed in 67.3, 33.6 and 52.7% respectively. Moderate and severe forms of OSA were found in 26 and 54% respectively. Severe OSA was more common in men (56 vs 33.3%; p = 0.15). There was a strong correlation of OSA with BMI (r = 0.378; p < 0.001), NC (r = 0.502; p < 0.001), and ESS (r = 0.304; p = 0.002). Conclusions: Obstructive sleep apnea in Indian patients has strong correlation with male sex and indices of body habitus.
