A randomized controlled trial to evaluate the effectiveness of a brief motivational intervention to improve exclusive breastfeeding rates: Study protocol

J Adv Nurs. 2019 Apr;75(4):888-897. doi: 10.1111/jan.13917. Epub 2019 Jan 15.


Aims: To estimate the effectiveness of a brief motivational intervention (BMI) in increasing the duration of exclusive breastfeeding in the first 6 months postpartum. A complementary aim was to examine a potential mediating role of breastfeeding self-efficacy in the effectiveness of the BMI.

Background: Breastfeeding is associated with benefits for babies and mothers' health. Among the pool of techniques used to encourage healthy behaviours, BMI is highlighted based on the principles of motivational interviewing. One of the main components of these interventions is the promotion of self-efficacy, which, in fact, is a key factor for breastfeeding success.

Design: A multi-centre randomized controlled clinical trial of parallel groups.

Methods: Women who begin to breastfeed in the first hour after birth will be randomly assigned to the intervention group (receiving a BMI at immediate postpartum plus a telephone booster at the 1st and 3rd month postpartum) or the control group (receiving standard breastfeeding education at the same time). Outcome measures include the following: breastfeeding, breastfeeding self-efficacy, general self-efficacy, and postnatal depression. Data will be collected before the intervention and at the 1st, 3rd, and 6th month after birth. The study protocol has been approved by Badajoz Ethics Committee of Clinical Research in October 2017.

Discussion: This study will identify the effectiveness of BMI in improving exclusive breastfeeding rates. The findings will give useful evidence to health professionals about how to support breastfeeding.

Impact: This study will address the low-exclusive breastfeeding rates, that in our country are far lower than World Health Organization's recommendation.

目的: 评估短暂动机干预(BMI)提高产后前6个月纯母乳喂养时间的有效性。 补充目的是检查母乳喂养自我效能在BMI有效性中可能存在的调和作用。 背景: 母乳喂养对婴儿和母亲的健康都有好处。在鼓励健康行为的潜在技术中,BMI因为其动机干预的原则而突出。其中一项主要的干预措施是提高自我效能,而这也是母乳喂养成功的关键因素。 设计: 平行组多中心随机对照临床试验。 方法: 出生后第一个小时开始母乳喂养的妇女将被随机分配到干预组(产后立即接受BMI,产后第一个月和第三个月接受电话辅助)或对照组(同时接受标准母乳喂养教育)。 结果测量包括以下内容:母乳喂养、母乳喂养自我效能、一般自我效能和产后抑郁。在干预前以及出生后1、3和6个月收集数据。2017年10月,巴达赫兹临床研究伦理委员会批准了该研究提案。 讨论: 本研究将确定BMI提高纯母乳喂养率的有效性。研究结果将为卫生专业人员提供关于支持母乳喂养的可靠证据。 影响: 本研究将解决纯母乳喂养率低的问题,在我国,纯母乳喂养率远低于世界卫生组织的建议喂养率。.
