Goitre prevalence of selected population in respect of age, sex, religion and caste was evaluated in the Murshidabad district of West Bengal during post salt iodization phase. The study was carried out on 9321 school children in the age group 6-12 years of both sexes from randomly selected 26 representative localities from all 26 Community Development Blocks. Children were clinically examined for goitre. Result showed that the prevalence of goitre was found at endemic level. The overall goitre prevalence was found 22.1%. Besides palpable goiter (2.5%), the prevalence of visible goiter (19.7%) in school children was prevalent. A gradual increase in goitre rate was found from the age of 6 yr till the age of 8 yr followed by a short decline at the age of 9 yr to 12 yr. Goitre was most prevalent in Hindus (23.7%) than Muslim (21.4%) communities. Among the Hindus, general caste (20.8%) students suffered more than Scheduled caste & Scheduled tribe (19.0%). These variations in goitre prevalence among different caste and religions might be due to their different environmental adaptability and dietary habit.
