The study objective was to identify demographic, medical, and health behavior factors that predict breastfeeding initiation in a rural population with low breastfeeding rates. Participants were 2323 women who experienced consecutive deliveries at 2 hospitals, with data obtained through detailed chart review. Only half the women initiated breastfeeding, which was significantly associated with higher levels of education, private insurance, nonsmoking and non-drug-using status, and primiparity, after controlling for confounders. Follow-up analyses revealed that smoking status was the strongest predictor of failure to breastfeed, with nonsmokers nearly twice as likely to breastfeed as smokers and with those who had smoked a pack per day or more the least likely to breastfeed. Findings reveal many factors placing women at risk for not breastfeeding and suggest that intervention efforts should encourage a combination of smoking cessation and breastfeeding while emphasizing that breastfeeding is not contraindicated even if the mother continues to smoke.
本研究旨在确定人口统计学、医学和健康行为因素，以预测低母乳喂养率的农村人群中母乳喂养的开始。参与者为 2323 名在 2 家医院连续分娩的女性，通过详细的图表审查获得数据。只有一半的女性开始母乳喂养，这与更高的教育水平、私人保险、不吸烟和不使用药物以及初产妇显著相关，在控制了混杂因素后。随访分析显示，吸烟状况是母乳喂养失败的最强预测因素，不吸烟者母乳喂养的可能性几乎是吸烟者的两倍，而每天吸烟一包或更多的人最不可能母乳喂养。研究结果揭示了许多使妇女面临不母乳喂养风险的因素，并表明干预措施应鼓励同时戒烟和母乳喂养，同时强调即使母亲继续吸烟，母乳喂养也不是禁忌。
