Objectives: To study the factors associated with stunted physical growth in primary school children and adolescents in the Burkina Faso Sahel.
Materials and methods: This was a secondary analysis of the data from the survey conducted by the Directorate of Nutrition in June 2016 in 13 primary schools. The baseline study was conducted from May 15 to 24, 2016. This secondary analysis of the database took place from March to August 2017. The study participants were made up of male and female students from public primary schools and who were beneficiaries of the school canteens of the Dori municipality at the time of the survey. Logistic regression was used to identify the factors associated with a 5% significance level.
Results: The analysis involved a sample of 568 students aged 5 to 15 years. Girls accounted for 52% of students. The prevalence of stunting was 32.92% (95% CI [29-36%]), it was 28.93% (95 % CI [23.84-34.62%]) among boys and 36.61 % (95% CI [31.28-42.28%]) in girls. Among primary students, age (ORa = 4.38, P = 0.00), anemia (ORa = 0.24, P = 0.01) and latrine use (ORa = 0.58 with P = 0.02) were the factors statistically associated with stunting (P < 0.05).
Conclusions: The prevalence of stunting among primary school students in the commune of Dori remains high. Associated factors were age, anemia and latrine use. Promotion of latrine use in households and prevention of anemia in children under 5 years of age would be necessary for the reduction of stunting among adolescents.
