The effects of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on breast-feeding behavior have been sometimes found inadequate. The determinants of breast-feeding initiation and duration among WIC participants and nonparticipants were modeled by using retrospective cross-sectional data from the 1988 National Maternal and Infant Health Survey. This study corrects for self-selection bias as far as the data allow, in addition to controlling for parents' ages, education, race, and family income. Findings suggest that prenatal WIC participation, combined with breast-feeding advice, significantly increases the initiation of breast-feeding but does not affect duration. The exact nature of effective breast-feeding advice given prenatally at WIC clinics is unclear and warrants further research.
妇女、婴儿和儿童特别补充营养计划（WIC）对母乳喂养行为的影响有时并不理想。利用1988年全国母婴健康调查的回顾性横断面数据，对WIC参与者和非参与者中母乳喂养开始和持续时间的决定因素进行了建模。除了控制父母的年龄、教育程度、种族和家庭收入外，本研究在数据允许的范围内纠正了自我选择偏差。研究结果表明，产前参与WIC并结合母乳喂养建议，可显著提高母乳喂养的开始率，但对持续时间没有影响。WIC诊所产前提供的有效母乳喂养建议的确切性质尚不清楚，值得进一步研究。
