Maternity care practices have been linked with higher chances of meeting breastfeeding intentions, but this relationship has not been examined using national data on US low-income women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).
Using data from the WIC Infant and Toddler Feeding Practices Study-2 on 1080 women who intended to breastfeed, we estimated risk ratios for associations between (1) each of 6 maternity care practices supportive of breastfeeding (breastfeeding within 1 hour of birth, showing mothers how to breastfeed, giving only breast milk, rooming-in, breastfeeding on demand, no pacifiers), (2) each practice adjusted for all other practices, and (3) total number of practices experienced with whether women met their intention to feed only breast milk at 1 month old. Models were adjusted for demographics.
In adjusted models (1), breastfeeding within 1 hour of birth, giving only breast milk, and no pacifiers were associated with higher likelihood of meeting prenatal breastfeeding intentions. Adjusting for all other practices (2), initiating breastfeeding within 1 hour of birth (risk ratio: 1.3; 95% confidence interval: 1.0-1.6) and giving only breast milk (risk ratio: 4.4; 95% confidence interval: 3.4-5.7) remained associated with meeting breastfeeding intention. There was a dose-response relationship between number of steps experienced and higher likelihood of meeting prenatal breastfeeding intentions (3).
Women who experienced maternity care practices supportive of breastfeeding were more likely to meet their prenatal breastfeeding intentions, underscoring the importance of breastfeeding support during the birth hospitalization in enabling mothers to achieve their breastfeeding goals.
产妇护理实践与提高母乳喂养意愿的机会相关,但这一关系尚未使用美国低收入妇女参加特殊补充营养计划妇女、婴儿和儿童(WIC)的全国数据进行检验。
利用 WIC 婴儿和幼儿喂养实践研究-2 的数据,对 1080 名打算母乳喂养的妇女进行分析,我们估计了以下因素之间的风险比:(1)6 种支持母乳喂养的产妇护理实践中的每一种(出生后 1 小时内母乳喂养、向母亲展示如何母乳喂养、仅提供母乳、母婴同室、按需哺乳、不使用安抚奶嘴),(2)每种实践调整所有其他实践,以及(3)经历的实践总数与妇女在 1 个月时仅母乳喂养的意图有关。模型根据人口统计学因素进行了调整。
在调整后的模型(1)中,出生后 1 小时内母乳喂养、仅提供母乳和不使用安抚奶嘴与更高的满足产前母乳喂养意愿的可能性相关。调整所有其他实践(2)后,出生后 1 小时内开始母乳喂养(风险比:1.3;95%置信区间:1.0-1.6)和仅提供母乳(风险比:4.4;95%置信区间:3.4-5.7)仍然与满足母乳喂养意图相关。经历的步骤数量与满足产前母乳喂养意图的可能性呈正相关(3)。
经历支持母乳喂养的产妇护理实践的妇女更有可能实现其产前母乳喂养意愿,这突显了在分娩住院期间提供母乳喂养支持对于帮助母亲实现母乳喂养目标的重要性。
