Despite the well documented health benefits of breastfeeding, initiation of breastfeeding and breastfeeding duration rates among black infants in the United States are approximately 16% lower than among whites. Although many factors play a role in a woman's ability to breastfeed, experiences during the childbirth hospitalization are critical for establishing breastfeeding. To analyze whether the implementation by maternity facilities of practices that support breastfeeding varied depending on the racial composition of the area surrounding the facility, CDC linked data from its 2011 Maternity Practices in Infant Nutrition and Care (mPINC) survey to U.S. Census data on the percentage of blacks living within the zip code area of each facility. The results of that analysis indicated that facilities in zip code areas where the percentage of black residents was >12.2% (the national average during 2007-2011) were less likely than facilities in zip code areas where the percentage was ≤12.2% to meet five of 10 mPINC indicators for recommended practices supportive of breastfeeding and more likely to implement one practice; differences for the other four practices were not statistically significant. Comparing facilities in areas with >12.2% black residents with facilities in areas with ≤12.2% black residents, the largest differences were in the percentage of facilities that implemented recommended practices related to early initiation of breastfeeding (46.0% compared with 59.9%), limited use of breastfeeding supplements (13.1% compared with 25.8%), and rooming-in (27.7% compared with 39.4%). These findings suggest there are racial disparities in access to maternity care practices known to support breastfeeding.
尽管母乳喂养对健康有益已得到充分证明,但美国黑人婴儿的母乳喂养起始率和母乳喂养持续率比白人婴儿低约16%。虽然许多因素影响女性的母乳喂养能力,但分娩住院期间的经历对建立母乳喂养至关重要。为了分析产科机构实施支持母乳喂养措施的情况是否因机构周边地区的种族构成而异,美国疾病控制与预防中心(CDC)将其2011年婴儿营养与护理中的产科实践(mPINC)调查数据与美国人口普查数据相链接,后者涉及每个机构邮政编码区域内黑人的百分比。该分析结果表明,邮政编码区域内黑人居民百分比>12.2%(2007 - 2011年全国平均水平)的机构,相比于黑人居民百分比≤12.2%的邮政编码区域内的机构,达到10项mPINC母乳喂养推荐实践指标中的5项的可能性更低,而实施一项实践的可能性更高;其他四项实践的差异无统计学意义。将黑人居民>12.2%地区的机构与黑人居民≤12.2%地区的机构进行比较,最大的差异在于实施与尽早开始母乳喂养相关推荐实践的机构百分比(分别为46.0%和59.9%)、限制使用母乳喂养补充剂的机构百分比(分别为13.1%和25.8%)以及母婴同室的机构百分比(分别为27.7%和39.4%)。这些发现表明,在获得已知支持母乳喂养的产科护理实践方面存在种族差异。
