我们使用英国出生在布拉德福德的研究来调查在低质量环境中的妇女是否不太可能母乳喂养。我们使用物理环境质量（水消毒剂副产品[DBPs]，空气污染，被动吸烟和家庭条件）以及社会经济指标的措施，详细探讨不同的暴露如何影响母乳喂养。根据进化生命史理论，我们预测，较低的环境质量将与较低的启动几率和较高的停止母乳喂养的风险有关。由于低的物理环境质量可能会增加不良出生结果的风险，这反过来可能会影响母乳喂养的机会，我们还测试了孕龄，出生体重，头围和腹围的中介。我们的样本由2007年3月至2010年12月期间在西约克郡布拉德福德皇家医院分娩的母亲组成，这些母亲的母乳喂养起始数据可用。分析按两个最大的种族群体分层：白色英国人（n = 3，951）和巴基斯坦裔（n = 4，411）母亲。在控制了社会经济地位后，巴基斯坦裔母亲开始母乳喂养的机会较低，停止母乳喂养的机会较高，水DBP暴露增加（例如，OR为0.03-0.61 vs.
We use the United Kingdom's Born in Bradford study to investigate whether women in lower quality environments are less likely to breastfeed. We use measures of physical environmental quality (water disinfectant by-products [DBPs], air pollution, passive cigarette smoke, and household condition) alongside socio-economic indicators, to explore in detail how different exposures influence breastfeeding. Drawing on evolutionary life history theory, we predict that lower environmental quality will be associated with lower odds of initiating, and higher hazards of stopping, breastfeeding. As low physical environmental quality may increase the risk of adverse birth outcomes, which may in turn affect breastfeeding chances, we also test for mediation by gestational age, birthweight, head circumference, and abdominal circumference. Our sample is composed of mothers who gave birth at the Bradford Royal Infirmary in West Yorkshire between March 2007 and December 2010 for whom breastfeeding initiation data was available. Analyses were stratified by the two largest ethnic groups: White British (n = 3,951) and Pakistani-origin (n = 4,411) mothers. After controlling for socio-economic position, Pakistani-origin mothers had lower chances of initiating and higher chances of stopping breastfeeding with increased water DBP exposure (e.g., OR for 0.03-0.61 vs.
