Changing Behavior and Nutrition through Health Education in China
Evidence from three randomized evaluations
This article studies whether or not health education programs targeting childhood anemia are sufficient for changing health behavior and nutrition in rural China. We conducted three different randomized-controlled trials of single and multiple face-to-face education sessions with parents and distributed written health education materials—and compare our results with a simple vitamin distribution program. Across all three studies, we find little evidence of changes in blood hemoglobin concentration or anemia status. In contrast, in our two studies that also examined a multivitamin supplementation intervention, we find meaningful reductions in anemia.
