Thyroid dysfunction in children and adolescence: Experience of a tertiary care centre in Kerala
Abstract
Background: There is limited data regarding the prevalence of thyroid disorders in children and adolescents from India.
Methods: All subjects aged 1-19 years, who underwent estimation of thyroid function tests (TFTs) at the EMS Memorial Cooperative Hospital and Research Centre, Perinthalmanna (2009-2013) were included in the study.
Results: A total of 784 subjects (males-336, females-448), aged between 1-19 (Mean 11.12, SD-6.23) years, who under-went estimation of TFTs were studied. The prevalence rate of all thyroid function abnormalities was 9.18%. The thyroid function disorders were more common (10.89%) in adolescents (14-19 years) than children (1-13 years) (7.82%) and in females (12.05%) than males (5.36%) in both age groups. The prevalence rates of subclinical hypothyroidism (SCH), overt hypothyroidism (OH) and hyperthyroidism were 4.08%, 3.05% and 2.04% respectively.
Conclusions: The thyroid function abnormalities are common in children and adolescents affecting about ~ 9% in study population. The SCH was the commonest thyroid function disorder, followed by OH and hyperthyroidism with female: male ratios of 2.5:1, 2.43:1 and 7:1 respectively. Majority of cases OH were of primary hypothyroidism. The SCH and hyperthyroidism were more prevalent in the adolescents than children; however, OH was more common in children than adolescents.
