Perception of affordable diet is associated with pre-school children’s diet diversity in Addis Ababa, Ethiopia: the EAT Addis survey

Abstract

Abstract Background Despite improvements in food access and nutrition security over the last few decades, malnutrition remains a major public health problem. One of the significant contributors to these problems is affordability of nutritious food. This study aimed to examine the association between perceived food affordability and pre-school children’s diet diversity in Addis Ababa, Ethiopia. Methods Cross-sectional data were used for the analysis. A 24 h dietary recall assessment was done to assess children’s dietary diversity (DD). We used a modified operational definition of affordability indicator called perceived affordability of dietary diversity (afford-DD) to evaluate the impact of the food environment in terms of affordability at the household level. A sample (n 4,898) of children aged 6–59 months representative of Addis Ababa was randomly selected using a multistage sampling procedure including all districts in the city. Mixed-effects linear regression models were used to assess the association between children’s DD and afford-DD. Results The survey revealed that the mean of children’s DD was 3.9 [± 1.4] while the mean of afford-DD was 4.6 [± 2.1]. Overall, 59.8% of children met the minimum dietary diversity (≥ 4 food groups). White roots and tubers were the most commonly consumed food groups regardless of their affordability. Considerable variations were observed between households that reported the food item affordable and not affordable in consumption of Vitamin A rich vegetables and fruits, meat and fish, egg, and dairy. The children’s DD was positively associated with afford-DD after adjusting for maternal education, household wealth status and other relevant confounding. Higher maternal education modified the association between affordability and children’s diet diversity. Conclusions This study suggests higher perceived food affordability was associated with better diet diversity in children. A higher level of maternal education had the potential to mitigate affordability challenges in meeting the children’s dietary diversity needs.
