Abstract

OBJECTIVES: Despite repeated governmental and nongovernmental interventions, anemia remains a widespread public health concern in Peru. This article examines nutritional and disease factors associated with the prevalence of anemia and response to iron supplementation in Peruvian children, with the aim of understanding the lack of success of national programs.
METHODS: Data come from children, aged 2-5 years (n = 102), living in peri-urban Lima. Predictors of anemia and response to iron supplementation were explored at the individual, maternal, household, and environmental levels using logistic regression models, adjusted for clustering by household.
RESULTS: Half of the children in this sample were anemic and 50% of the anemic children responded to iron supplementation. We identified several factors that were associated with child anemia status and response to iron supplementation. Lower weight-for-age z-scores and the winter season were strong predictors of child anemia status and nonresponse to iron supplementation. Living with paternal grandparents was protective against anemia and elevated C-reactive protein at the time of the final interview was associated with a lack of response to iron supplementation.
CONCLUSIONS: The findings of this study document an association between children's anemia status and their nutritional and ecological environment, highlighting the importance of examining anemia within a specific context to better understand the factors driving this important health problem.
