Background: Ageing process can cause some changes in body system controlling mechanism. Consequently thyroid hormone levels may show variations reflected by TSH level in elderly people, more so in females.Methods: Serum TSH level were measured in 304 apparently healthy females of Dibrugarh town, Assam. Unbound T3 and T4 were measured if TSH level was abnormal. TSH levels were compared among different age groups.Results: The prevalence of hypothyroidism was found to be 8.2% in premenopausal and 12.7% in postmenopausal women. There were more cases of subclinical hypothyroidism than clinical hypothyroidism. Difference of Mean± SEM of TSH level in these two groups was significant though there was no correlation between age and TSH level.Conclusions: The study reveals decreasing thyroid function in postmenopausal female population of Dibrugarh town.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
