ABSTRACT

BACKGROUND

Obesity is known to be associated with altered thyroid function, increased risk of cardiovascular diseases, diabetes, insulin resistance and metabolic disorders. Thyroid hormones affect body weight through modification of basal metabolic rate.

The study aims to assess the BMI and correlate with TSH, f T3, f T4, body fat % and visceral fat level in healthy euthyroid individuals to see if any association between obesity and thyroid status exists.

 

MATERIALS AND METHODS

This study was conducted on 92 healthy volunteers amongst the staffs of Jawaharlal Nehru Institute of Medical Sciences (JNIMS), Imphal, Manipur. Anthropometric measurements were done and Body Mass Index (BMI) was calculated. Thyroid Stimulating Hormone (TSH), f T3 and f T4 levels were measured by using chemiluminescent immunoassay and subjects with TSH value between 0.3 - 3.6 mIU/L were taken for the study. Body fat % and visceral fat level were measured by Bioelectrical Impedance (BI) method by using OMRON-HBF-212 (Body Composition Monitor). Data was analysed using SPSS version 22. The association between variables was determined using ANOVA.

RESULTS

The study showed significant association of TSH (p= 0.025), body fat % (p= 0.000) and visceral fat level (p= 0.000) with BMI. There was no statistically significant association between body fat % and TSH, f T3, f T4. There was significant association between visceral fat level and f T3.

CONCLUSION

Serum TSH level increases with increase in fat content of the body, even if the upper limit of TSH is within normal limits. This increased level of body fat % and visceral fat level in obese euthyroid individuals may lead to increased risk for development of obesity related common health problems, thus arising the need to keep the body weight, body fat % and visceral fat level at an acceptable level.

KEY WORDS

TSH, BMI, Body Fat %, Visceral Fat Level, Euthyroid.
