Dietary diversity and associated factors among school-aged children and adolescents in Lokossa district of southern Benin: a cross-sectional study.

OBJECTIVE: The main objective of this study was to assess the prevalence of dietary diversity and associated factors. DESIGN: Cross-sectional study. SETTING: Lokossa district, southern Benin. PARTICIPANTS: A survey conducted in a probabilistic sample of 612 students (345 boys and 267 girls), aged 8-17 years old from 26 primary schools. Dietary Diversity Scores were calculated by summing the number of food groups consumed by the schoolchildren and adolescents over a 24-hour recall period. Adequate dietary diversity can be assigned to a consumption that is greater than or equal to five food groups, and inadequate dietary diversity can be assigned to a consumption that is lower than five food groups. Descriptive statistics such as frequency, mean and SD were computed. Statistical analysis was performed on the data to determine which variables were associated with dietary diversity as well as the results of the adjusted OR with a 95% CI. A p<0.05 was considered statistically significant. RESULTS: The proportion of schoolchildren and adolescents with inadequate dietary diversity was 25.8% (95% CI 15.1% to 40.5%). Schoolchildren and adolescents living in rural areas, having low household socioeconomic status, eating breakfast less than 5 days per week and no eating school meals were significantly associated with inadequate dietary diversity. CONCLUSIONS: The results of this study revealed that the diet among schoolchildren and adolescents lacked diversity and is associated with socioeconomic status, rural living, eating breakfast and school meals. Public health interventions, such as school meal programmes in rural and isolated areas, in association with poverty-reducing programmes and nutrition education, are recommended to improve the quality of diet and limit the consequences of poor diet diversity.

Socio-economic determinants of healthy behaviours among primary schoolchildren and adolescents in Lokossa district of southern Benin.

BACKGROUND: There is little information regarding fruit and vegetable (FV) intake and physical activity (PA) among schoolchildren in Benin. In this study we evaluated the differences in breakfast eating, FV consumption and PA according to socio-economic (SE) determinants in primary schoolchildren. METHODS: A cross-sectional study using a probabilistic sample of 612 students (8-17 y of age) from 26 primary schools was done between December 2018 and January 2019. The association was estimated by logistic regression analyses. RESULTS: Of all students, 53% were physically inactive, 60% took breakfast <5 d/week, 84% irregularly ate fruits and 68% irregularly ate vegetables. Younger students (8-10 y) take breakfast regularly and older ones (>15 y) were physically more active. The probability of regular breakfast and fruit consumption were significantly higher in children of educated parents (p<0.01 and p<0.001, respectively) compared with children of non-educated parents. Medium SE status was associated with regular breakfast intake, whereas high SE status was associated with higher fruit intake and lower physical activity compared with low SE status (p<0.001). There was no association between breakfast eating, FV intake, PA and the body mass index. CONCLUSIONS: Findings emphasize the need for interventions to promote healthy eating behaviours in primary schoolchildren and their family environments.
