ANTHROPOMETRICAL CORRELATES OF SLEEP AND METABOLIC PARAMETERS: A TERTIARY CENTER SLEEP LAB BASED STUDY

Abstract

Obstructive Sleep Apnoea Syndrome (OSAS) is a disorder characterized by repetitive complete or partial upper airway collapse occurring during sleep. OSAS leads to adverse medical conditions, including hypertension, cardiovascular disease, stroke, and insulin resistance . OSAS is estimated to be 7.5 per cent in males between 35-65 yr of age in the urban Indian population. Obesity is the most important risk factor for OSAS. This hospital based study was designed to study, sleep and metabolic correlates of anthropometric variables in north Indian population. Study was performed with one hundred and ninety subjects as per inclusion and exclusion criteria. Anthropometrical, overnight polysomnography, vital and biochemical data were collected and analyzed. Significant differences were found in mean values of anthropometrical, AHI, Obstructive events and Hypopnea events between OSAS and Non OSAS subjects. BMI, Neck Circumference, waist circumference and Waist Hip Ratio of subjects were observed significantly correlated with metabolic and sleep related variables.
