Abstract

Hypothyroidism reduces thyroid hormone levels, slowing metabolism and is prevalent in India. Therefore, it is of interest to relate hypothyroidism and poor sleep among first-year medical students in eastern India. Hence, an Observational Cross-sectional study was conducted on apparently healthy students aged 18-25 years of a Medical College of Eastern India. Socio -demographics, anthropometric measurements, Free T4, TSH and Sleep quality (PSQI) were assessed. 17.241% students had Hypothyroidism, 9.195% students had Subclinical Hypothyroidism, 44.83% students were found to have poor sleep. Female students had significantly more FT4, TSH and poorer sleep quality than male students. (p=0.0282, p=0.0111 and p=0.0094). A strong positive correlation was found between serum TSH levels and PSQI scores (R =0.786). Thus, there is a significant burden of hypothyroidism, subclinical hypothyroidism and poor sleep quality among medical students. There is also a strong association between elevated serum TSH levels and impaired sleep quality.
