In 2007, Bangladesh's national strategy to reduce anemia included iron and folic acid (IFA) supplementation to adolescent girls and newly married females. We conducted a double‐blinded RCT among married, nulliparous females to determine the impact of daily periconceptional IFA Sprinkles® versus folic acid (FA) Sprinkles® on iron and folate status. Biochemical indices were collected at baseline and after a positive urine pregnancy test (~15 wks gestation), or after 9 mo of supplementation among non‐pregnant females (NPF). Among 88 pregnant females (PF), there was a significant interaction between treatment group and length of supplementation for Hb (p=0.01) and anemia (p=0.02). After 183 study days, IFA improved Hb (127.0 vs 112.5 g/L) and reduced anemia (22.2% vs 66.7%) compared to FA. Group differences for iron status were not significant. Among NPF (n=151), IFA reduced anemia by 81.4% (95% CI: 0.04, 0.90, p=0.04) and ID by 91.8% (95% CI: 0.01, 0.68, p=0.02). Improved ferritin levels were only observed among females in the highest quartile of adherence. Periconceptional FA improved folate status in both groups. Mean ( ±SD) plasma folate increased from 18.0 ( ±7.0) to 33.8 ( ±23.8) nmol/L after 140.3 ( ±65.5) days of supplementation among PF and from 16.6 ( ±6.8) to 31.4 ( ±18.8) nmol/L after 277.4 ( ±5.2) days of supplementation among NPF. Among NPF, adherence was significantly associated with improved plasma folate levels (p<0.0001) and reduced folate deficiency (p=0.002). We conclude that periconceptional IFA supplementation with Sprinkles® significantly improves anemia and iron and folate status before and during pregnancy among females in rural Bangladesh.
