Relative Efficacy of Micronutrient Powders versus Iron—Folic Acid Tablets in Controlling Anemia in Women in the Second Trimester of Pregnancy

BACKGROUND: Iron deficiency is a major cause of anemia and the most prevalent nutrient deficiency among pregnant women in developing countries. The use of iron and folic acid supplements to treat and prevent iron-deficiency anemia has limited effectiveness, mainly due to poor adherence. Home fortification with a micronutrient powder for pregnant women may be an effective and acceptable alternative to traditional drug models.

METHODS: A cluster-randomized noninferiority trial was conducted in the rural subdistrict of Kaliganj in central Bangladesh. Pregnant women (gestational age 14-22 weeks, n=478), were recruited from 42 community-based Antenatal Care…
