Background:
Iron deficiency anemia affects millions of children worldwide. Iron intake assessments can inform targeted interventions.
Methods:
This cross-sectional study describes diet and hemoglobin levels of children 1-5 y of age in a resource-limited setting in the Dominican Republic. The study team performed meal observations and measurements, dietary questionnaires, and point-of-care hemoglobin testing.
Results:
Iron intake and bioavailability were low, with liberal estimates indicating that not more than 40% of subjects consumed the recommended daily allowance for iron. Forty of 80 children had anemia, with 23% demonstrating moderate or severe anemia.
Conclusions:
Poor observed iron intake likely contributes to the high prevalence of anemia in this population.
