Extant data from prenatal patients in Massachusetts were analyzed to evaluate the effects of WIC supplemental feeding on birth outcomes. A total of 418 pairs of WIC and non-WIC women were directly matched for racial/ethnic group, age, parity, marital status, and income. Participation in WIC supplemental feeding appears to have a positive effect on pregnancy outcome. Participation in WIC is associated with a 107 g increase in mean birth weight (p = 0.012) and a 4.0% decrease in the incidence of low birth weight (p = 0.059). Teenage, Black, and Hispanic women show similar, if not stronger, benefits.
对马萨诸塞州产前患者的现有数据进行了分析，以评估妇女、婴儿与儿童营养补充计划（WIC）补充喂养对出生结局的影响。总共418对参与WIC和未参与WIC的女性在种族/族裔、年龄、胎次、婚姻状况和收入方面进行了直接匹配。参与WIC补充喂养似乎对妊娠结局有积极影响。参与WIC与平均出生体重增加107克（p = 0.012）和低出生体重发生率降低4.0%（p = 0.059）相关。青少年、黑人及西班牙裔女性显示出相似的益处，即便不是更强的益处。
