Abstract
Anemia is a multicausal problem affecting 41.7% of children under 5 worldwide. The prevalence of anemia in Peru has decreased only 6.8% from 2009 to 2017, despite great efforts made to distribute free multi-micronutrient supplements and promote the consumption of iron rich foods. The current study investigates the nutritional uptake and incidence of disease in children with anemia in Peru to better understand what is driving the high rates of anemia. METHODS A cross-sectional analysis of secondary data was conducted. Data from two national surveys were linked to evaluate the predictors of anemia. The associations were tested with Chi-square analysis and logistic multivariate regression analysis. RESULTS The sample included 586 children under 3. The prevalence of anemia was 53.2%, while 51.9% of the children consumed sufficient micronutrients to meet the daily recommended level for their age. Of those with anemia, 45.1% consumed sufficient micronutrients to meet the recommended level (p<0.001). The children with anemia were more likely to have an infectious or parasitic disease in the last year and less likely to have access to safe drinking water (p=0.057, p=0.002, respectfully). The logistic analysis displayed that having an infectious or parasitic disease increased the odds of having anemia (OR=1.6, p=0.043), and having access to safe drinking waters decreased the odds of having anemia (OR=0.58, p=0.044), while controlling for micronutrient uptake. CONCLUSIONS Nearly half of the children with anemia in Peru already consume sufficient nutrients to meet their daily requirement. However, they continue to have anemia, likely due to infectious diseases and parasites.
