This abstract was presented at the 9th JPEF Annual Global Diabetes Convention 2021 and had won the second prize.

      Clinically, subclinical hypothyroidism is frequently seen in patients with type 2 diabetes mellitus (T2DM). However, the association between subclinical hypothyroidism (SCH) and T2DM remains unknown.

A cross-sectional study was conducted among 95 participants divided into diabetic (n=50, 52.63%) and non-diabetic (n=45, 47.36%) group. The study variables were age, BMI, blood pressure, HbA1c, BUN, lipid profile, and thyroid profile. Subclinical hypothyroidism (SCH) was diagnosed when Thyroid-stimulating hormone (TSH) was more than 4.0 mIU/L with a normal level of free thyroxine (T4: 0.7-1.4 ng/dL). HbA1c was used to sub-group the diabetic group. The association between T2DM and SCH was determined using Chi-square.

The results showed that the prevalence of SCH was increased with the highest HbA1c group compared with the diabetes controlled group (HbA1c>7) and is similar between the people with and without diabetes.
