标题：Multiple micronutrient supplementation improves growth and reduces the risk of anemia among infants in Gaza Strip, Palestine: a prospective randomized community trial
摘要：Infants and young children 6–24 months of age are the most nutritionally vulnerable groups, as their needs for vitamins and minerals are high relative to the amount of food they consume. This study determines the effect of Micronutrient Powder Supplementation (MNP) on growth and hemoglobin of infants in Gaza Strip, Palestine. This was a two-arm parallel-group randomized controlled trial conducted in two health care clinics of the United Nations Relief and Work Agency (UNRWA) at the Middle Area governorate of Gaza Strip, Palestine. A total of 200 healthy infants aged 6-month-old were recruited and randomized to receive 3 sachets/week of MNP for 12 months alongside with the National Micronutrient Supplement (NMS) (n = 100) or NMS alone (n = 100). Weight, length, blood hemoglobin, and dietary intakes were measured at 6, 9, 12, 15, 18, and 21 (3 months after the end of intervention) months of age. Analysis was by intention to treat. The experimental group had a higher concentration of hemoglobin at 12 and 15 months than did the control group, and a significant difference (p < 0.05) was observed at 15 months only. Significantly greater weight, length, weight-for-age, length-for-age, and weight-for-length z-scores were observed in the experimental group than that in the control group at 12 and 15 months (p < 0.05). The prevalence of anemia (18% vs. 52%) and stunting (1% vs. 11%) were higher in the control than the experimental group, respectively. After controlling for sex, similar findings were reported. Addition of MNP to the existing NMS program improved the nutritional status of young children. The potential benefits of MNP supplementation on physical growth and hemoglobin should be considered in the existing NMS program.
