ABSTRACT
Introduction: The relationship between OSA and glycemichealth is a topic of increasing clinical and research interest.Community-based studies have suggested that the presenceand severity of OSA are independent predictors of insulinresistance and T2DM prevalence the aim of the present studywas to examine the potential correlation of OSA and HbA1Cvalues in patients with Metabolic SyndromeMaterial and Methods: A cross-sectional study was conductedamong a total of 63 patients with a history of metabolicsyndrome and were divided into two groups diabetic and nondiabetic. The risk of OSA was assessed by three structuredand validated questionnaires namely STOP-BANG, ESS,Modified Berlin. Fasting blood sugars and HbA1C was done.All patients were evaluated with Polysomnography level III.Results were analyzed using statistical methods (Descriptiveanalysis and correlation). Using SSPS version 22 used.Results: Out of the total of 63 subjects, there was a malepreponderance (Male - 61%) with a mean age of 50.9 ± 12.98years. Increased AHI was seen in 91% of the subjects (morethan 5) with the mean AHI of 29.63 ± 22.14. The mean FBS &HbA1C was 151.62 ± 49.5mg/dl & 7.22 ± 1.71 respectively.In both diabetic & non-diabetic groups, the correlation of FBS& HbA1C values with AHI was statistically not significant.Conclusion: AHI severity did not correlate with FBS andHbA1c values in patients with metabolic syndrome. However,in the non-diabetic subgroup with severe AHI the fastingblood sugar levels were above a higher limit of normal.
