Micronutrients and socio-demographic factors were major predictors of anaemia among the Ethiopian population (2023)
Journal Article
Belay, A., Joy, E. J., Lark, R. M., Ander, E. L., Young, S. D., Bailey, E. H., …Gashu, D. (2023). Micronutrients and socio-demographic factors were major predictors of anaemia among the Ethiopian population. British Journal of Nutrition, 130(12), 2123-2135. https://doi.org/10.1017/S0007114523001472

Anemia is characterized by low hemoglobin (Hb) concentration. Despite being a public health concern in Ethiopia, the role of micronutrients and non-nutritional factors as a determinant of Hb concentrations has been inadequately explored. This study f...
