Interpregnancy WIC supplementation was evaluated by comparing maternal nutritional status indicators and subsequent birth outcomes of 703 WIC participants divided into two groups. Study group women received postpartum benefits for 5-7 mo while control group women received postpartum benefits for only 0-2 mo. Both groups received prenatal benefits during each of two study pregnancies. Infants born to study group women had a higher mean birthweight (131 g) and birthlength (0.3 cm) and a lower risk of being less than or equal to 2500 g. Additionally, at the onset of the second pregnancy study group women had higher mean hemoglobin levels and lower risk of maternal obesity. These results suggest that postpartum WIC supplementation has positive benefits for both the mother and her subsequent infants.
通过比较分为两组的703名妇女、婴儿与儿童营养补充计划（WIC）参与者的孕产妇营养状况指标和随后的出生结局，对孕期WIC补充进行了评估。研究组妇女接受了5至7个月的产后福利，而对照组妇女仅接受了0至2个月的产后福利。两组在两次研究孕期的每一次中均接受了产前福利。研究组妇女所生婴儿的平均出生体重更高（131克）、出生身长更长（0.3厘米），体重小于或等于2500克的风险更低。此外，在第二次怀孕开始时，研究组妇女的平均血红蛋白水平更高，孕产妇肥胖风险更低。这些结果表明，产后WIC补充对母亲及其随后的婴儿均有积极益处。
