Peer support intervention (ABA-feed) to improve breastfeeding: UK based, multicentre, parallel group, randomised controlled trial.

Methods

UK based, multicentre, parallel group, unblinded, randomised controlled trial.

英国的多中心、平行组、非盲、随机对照试验。

17 localities in the UK that offered breastfeeding peer support as part of usual care between January 2022 and 30 April 2024.

在2022年1月至2024年4月30日期间，英国17个地区将母乳喂养同伴支持作为常规护理的一部分提供。

2475 nulliparous women between 20 and 35 weeks of gestation were randomised 1.43:1, to account for potential clustering by peer supporter: 1458 to the ABA-feed (Assets based feeding help Before and After birth-feed) peer support intervention and 1017 to usual care.

共有2475名孕20至35周的初产妇被随机分配，比例为1.43:1，以考虑同伴支持者可能的聚集效应：1458名接受ABA喂养（产前和产后喂养帮助的资产基础喂养支持）同伴支持干预，1017名接受常规护理。

The ABA-feed intervention comprised person centred proactive peer support for infant feeding underpinned by an assets based approach (focusing on the capabilities of, and resources available to, participants) and behaviour change theory delivered in person and remotely by text and telephone call.

ABA干预措施包括以资产为基础的方法（关注参与者的技能和可利用资源）和行为改变理论支持的个人中心的积极同伴支持婴儿喂养，通过面对面以及通过短信和电话进行远程传递。

Usual care included universal care from midwives and health visitors and could also include services that provided reactive support such as peer supporters in breastfeeding groups, counselling, helplines, and social media support groups.

常规护理包括来自助产士和健康访视员的普遍护理，并且也可以包括提供反应性支持的服务，如母乳喂养小组的同伴支持者、咨询、热线电话和社交媒体支持小组。

The primary outcome was any breastfeeding at eight weeks after birth.

主要结果是在出生后八周内的任何母乳喂养。

Secondary outcomes at eight, 16, and 24 weeks after birth included breastfeeding initiation, any and exclusive breastfeeding, formula feeding practices, anxiety, social support, and healthcare utilisation.

次要结果包括在出生后八周、16周和24周的母乳喂养开始、任何和纯母乳喂养、配方奶喂养实践、焦虑、社会支持和医疗利用情况。

Analyses were based on the intention-to-treatprinciple.

分析基于意向治疗原则。

Results

Rates of any breastfeeding at eight weeks did not differ between the intervention group (1013/1452; 69.8%) and usual care group (698/1015; 68.8%); adjusted risk difference 0.01, 95% confidence interval-0.03 to 0.04.

八周时，任何母乳喂养的比例在干预组（1013/1452；69.8%）和常规护理组（698/1015；68.8%）之间没有差异；调整后的风险差异为0.01，95%置信区间为-0.03到0.04。

Preplanned subgroup analyses showed no interactions between the intervention and age, prespecified feeding intentions, mother's education, index of multiple deprivation fifth, or relationship status.

预先计划的亚组分析显示，干预措施与年龄、预先设定的喂养意图、母亲的教育程度、多重剥夺指数第五级或关系状况之间没有交互作用。

Breastfeeding initiation rates were high (intervention 94.2%; usual care 92.5%).

母乳喂养的开始率很高（干预组为94.2%；常规护理组为92.5%）。

At eight weeks the intervention group reported higher social support, but this was not sustained at 16 weeks.

在第8周时，干预组报告了更高的社会支持，但这种优势在第16周时并未持续。

No differences were observed in other secondary outcomes.

其他次要结果未观察到差异。

Conclusions

The ABA-feed peer support intervention did not improve breastfeeding rates compared with usual breastfeeding support in a UK context.

在英国背景下，ABA-feed同伴支持干预并未改善与常规母乳喂养支持相比的母乳喂养率。
