Background: Abdominal obesity or increase in waist circumference is one of the important components of metabolic syndrome. In this study the association between waist circumference (abdominal obesity) with subclinical hypothyroidism (SCH) was analysed. Objective: To identify patients with and without abdominal obesity. To assess the association between subclinical hypothyroidism and abdominal obesity in these two groups. Methodology: 75 subjects with abdominal obesity and 75 with normal Waist circumference (WC) were enrolled and BMI, Blood pressure (BP) and serum free T3, free T4, and TSH were done. Statistical analysis: Base line characteristics of the study participants are expressed as Mean ± SD and percentage. The difference in anthropometric and biochemical parameters in the study group and control group was analysed by student‘t’ test. Results: In the study group 55 subjects (73%) were euthyroid, 20 subjects (27%) had subclinical hypothyroidism. Interestingly in the control group 66 subjects (88%) were euthyroid, 9 subjects (12%) had subclinical hypothyroidism. This shows that in our study abdominal obesity and SCH have statistically significant association.
