To assess whether a phone-based breastfeeding intervention delivered by lactation educators influenced exclusive breastfeeding rates amongst low-income Hispanic women in the USA.
Randomised two-group design.
Pregnant low-income Hispanic women (298) were recruited from community health clinics in Los Angeles County (USA) and randomly assigned to either a control or an intervention group.
Data relating to the factors associated with breastfeeding were collected during the third trimester. Breastfeeding outcome data was collected at 72 hours, one month, three months, and six months postpartum.
There were no differences between the groups in rates of breastfeeding initiation. There was a significant difference in the duration of exclusive breastfeeding among participants during the infant's first week of life. While not significant, after controlling for covariates and intent to breastfeed at third trimester, the duration of exclusive breastfeeding amongst all participants was, on average, longer for intervention group mothers than control group mothers. Additionally, , the intervention group mothers were more likely to report exclusive and only breastfeeding at all data points compared to the control group, and less likely to discontinue breastfeeding.
Findings from this study suggest that telephone-based breastfeeding interventions delivered by a lactation educator show promise as a cost-effective strategy for improving both the quantity and duration of breastfeeding among low-income Hispanic women in the USA. Intervention group mothers not only sustained breastfeeding for a longer durations, but also provided their infants with greater amounts of breast milk over these longer durations.
评估由哺乳教育者提供的基于电话的母乳喂养干预措施是否会影响美国低收入西班牙裔女性的纯母乳喂养率。
随机两组设计。
从美国洛杉矶县的社区健康诊所招募了298名低收入西班牙裔孕妇,并将她们随机分为对照组或干预组。
在孕晚期收集与母乳喂养相关因素的数据。在产后72小时、1个月、3个月和6个月收集母乳喂养结果数据。
两组在母乳喂养开始率方面没有差异。在婴儿出生后的第一周,参与者之间的纯母乳喂养持续时间存在显著差异。在控制协变量和孕晚期母乳喂养意愿后,虽然差异不显著,但干预组母亲的纯母乳喂养总时长平均比对照组母亲更长。此外,与对照组相比,干预组母亲在所有数据点更有可能报告纯母乳喂养且仅进行母乳喂养,并且停止母乳喂养的可能性更小。
本研究结果表明,由哺乳教育者提供的基于电话的母乳喂养干预措施有望成为一种具有成本效益的策略,以提高美国低收入西班牙裔女性母乳喂养的量和持续时间。干预组母亲不仅母乳喂养持续时间更长,而且在这些较长时间内为婴儿提供了更多的母乳。
