Chronic undernutrition (stunting) is detrimental to academic performance among primary schools of adolescent children: a randomized cross sectional survey in Southern Ethiopia.

OBJECTIVE

Despite several decades of work in improving childhood nutrition in Ethiopia, stunting remains a major public health concern with lack of evidence on its effect on school performance. Therefore, this study aimed at determining prevalence of stunting and the impact on academic performance among schoolchildren attending primary schools in Meskan District of Southern Ethiopia.

RESULTS

During October 2016, we interviewed primary school children and their parents, collected anthropometric measurements of children, and conducted school record reviews among 408 randomly selected children attending ten primary schools. Univariate and multivariable linear regression were performed to assess stunting associated with academic performance among schoolchildren. A total of 378 primary schoolchildren were involved in the study giving a response rate of 93%. The prevalence of stunting was 16.9%. Grade repetition, place of residence, class rank of students and absenteeism from the class was negatively associated with the academic performance. In general, the present study children had relatively high prevalence of chronic undernutrition. We found that school underperformance was significantly high in the study area. The study underlines the need for nutrition interventions targeting rural areas to improve children's academic performance.
