Background: The thyroid function disorders are one of the commonest endocrine disorders in the world, elderly being one of the most vulnerable groups of patients affected. Arecent report shows that 300 million people in the world are suffering from thyroid disorders and among them, about 42 million people reside in India.1 The etiologic factors for thyroid disorders in elderly are multiple in addition to numerous changes occur in thyroid with age, contributing to raise in prevalence of thyroid disorders in elderly and their diagnosis is not easy as only one third patients show typical signs and symptoms which many a times are attributed to ageing process.2,3 The objectives of this study were to assess the prevalence of thyroid dysfunction in elderly population aged >60yrs, to correlate clinical prole with biochemical thyroid dysfunction and to study prevalence of dyslipidaemia in patients with dysfunction. Methodology: Cross sectional study involving total of 130 participants who visited Medicine/Geriatric OPD patients of age >60 years are selected by convenient sampling. Clinical and biochemical data were documented in the data reporting form. Duration of study was 2years (September 2017 – September 2019). Descriptive statistics reported as mean and SD for the continuous variables, number and percentages for the categorical variables. The proportion of thyroid dysfunction reported using percentages. Association with clinical parameters done using chi-square test or independent t-test as appropriate. A p-value less than 0.05 considered as statistically signicant. Results: A total of 130 patients were studied, mean age of study subjects were 76.81 ± 9.072years. The thyroid function abnormalities were found in 19.3 % of 130 patients. Of the 19.3% of subjects - 3.1% were hyperthyroid, 3.1% were sub-clinical hypothyroid and 13.1% were hypothyroidism. The prevalence rate of thyroid function abnormalities was more in females. (F-19.64% and M-18.9%). (p- 0.539). Patient with thyroid dysfunction were more in urban (53.1%) than rural.(49.1%) (p- 0.043). Commonest comorbidities noted in study population was dyslipidaemia followed by hypertension. Commonest symptoms noted are generalised weakness (p-<0.001) and dry skin as commonest sign. Dyslipidaemia (Total cholesterol (p -0.008) and triglycerides(p-0.015) )signicantly more in study population with thyroid dysfunction in comparison with group with normal thyroid functions. Conclusions:This study shows prevalence of 19% for thyroid disorders in the elderly and it often presents with vague and non-specic symptoms. It showed overt hypothyroidism as the common variety of thyroid dysfunction in elderly, and more common in females than males. The nding that a large number of elderly patients unknowingly have laboratory evidence of thyroid dysfunction with few or minimal symptoms and the fact that it can mimic many other clinical and psychiatric conditions supports the usefulness of screening of thyroid function as part of routine investigations after age of 60 years, for early detection and treatment to reduce the ill effects of thyroid dysfunction.
