Abstract :
Introduction: Vitamin D deficiency has been identified as a risk factor for several autoimmune diseases, cancers, atherosclerosis, etc. Its deficiency has also been shown to be associated with hypothyroidism with inconclusive results. The present study aims to explore the association of vitamin D deficiency with hypothyroidism.
Materials and Methods: This is a cross sectional study conducted in the department of biochemistry Subharti Medical College, Meerut. A total of 152 clinically suspected hypothyroid subjects in the age group of 20-60 years, from both sexes attending Medicine OPD were included in the study.
All the patients were subjected to complete general physical and systemic examination and findings noted. The vitamin D, T3, T4 and TSH were measured in all by enzyme linked fluorescence assay (ELFA) in Vidas PC auto-analyzer from Biomerieux. The patients were then categorized into euthyroid (TSH=0.25-5?IU/ml), subclinical hypothyroid (TSH ?5-7?IU/ml) and overt hypothyroid (TSH?7?IU/ml) based on serum TSH cut off values. The patients were also defined as vitamin D sufficient (?30ng/ml), insufficient (20-30ng/ml) and deficient (
