The effect of iodine-deficiency disorders on academic achievement of schoolchildren in Southern Ethiopia

Objective The present study aimed to assess the effect of iodine deficiency on academic achievement of schoolchildren in Wolaita Sodo town, Southern Ethiopia. Design School-based comparative cross-sectional study. Settings Primary school in Sodo town, Southern Ethiopia. Subjects A sample population of 270 children with goitre and 264 without goitre. All students in each class were examined for the presence of goitre and classified based on WHO recommendations. Results Among children with goitre, a higher proportion (54·8 %) was female and the proportion increased with age. The odds of scoring low on school performance was higher among children whose fathers were illiterate (adjusted OR = 1·9; 95 % CI 1·1, 3·5) and those who were absent for more than 5 d in the last academic year (adjusted OR = 1·5; 95 % CI 1·1, 2·3). Goitre was significantly associated with low academic achievement (adjusted OR = 1·8; 95 % CI 1·2, 2·5). Conclusions The study showed that the presence of goitre has a negative effect on academic achievement even after accounting for parental education and absenteeism from school. Awareness of endemic goitre and its impact on school performance, and an emphasis on prevention and control by concerned bodies, are recommended to alleviate the problem
