Background
Child malnutrition remains a public health problem affecting both children under 5 years of age and adolescents in Burkina Faso. However, school-age children are not always considered in programs to reduce malnutrition, despite their negative impact on school performance. This study sought to identify the factors associated with the nutritional status of students in public primary schools.
Method
Three-stage sampling was used to select 559 students aged 5–14 years enrolled in 24 public elementary school. Face- to- face interview using a structured questionnaire were used to collect information from children and their parents. Z-scores for weight-for-age, height-for-age, and BMI-for-age were calculated using the AnthroPlus software to determine the prevalence of all aspects of malnutrition among the studied children. Binary logistic regressions were used to examine factors associated with malnutrition.
Results
The sample included 52.8% girls, with an average age of 10.79 years. The prevalence of undernutrition was 35.8%, with 12.9% for stunting, 9.1% for underweight, and 13.8% for thinness. The prevalence of being overweight and obese was 0.7%. Stunting is significantly associated with 5–10 age and water from non-portable sources. Being underweight is associated with living in the province of Kourwéogo and the father's lack of of schooling. Leanness is positively associated with the 5 to 10 age group, non-deworming of pupils and the father's occupation as a trader.
Conclusion
Undernutrition is a real health problem among students in public primary schools in the Plateau Central region of Burkina Faso. Actions to prevent undernutrition must be undertaken to benefit school-age children.
