Breastfeeding has important positive long-term health consequences for infants and mothers. The World Health Organization recommends that all infants should be exclusively breastfed for six months or longer, and advises continuation of breastfeeding for two years or beyond. However, these recommendations are not met in many countries. This study examined whether a comprehensive, evidence-based breastfeeding intervention, the Breastfeeding Support Programme (BSP), promotes prolonged duration and exclusivity of breastfeeding among its participants.
A quasi-experimental design was used to compare breastfeeding duration and exclusivity in the BSP group (N = 66) to breastfeeding duration and exclusivity in a control group (N = 72). Participants who followed the BSP were provided with 6 consults delivered by a lactation consultant. The consults started during pregnancy and continued up until 10 weeks after delivery. Participants in the control group did not follow the BSP. Pretest and posttest questionnaires were administered through the internet. A Cox proportional hazards regression analysis was used to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for cessation of any and exclusive breastfeeding, while controlling for differences at baseline.
The effect of the BSP on survival rates for any and exclusive breastfeeding were significant while controlling for differences between the two groups at baseline (respectively HR = 0.34, p < .001 [95% CI = 0.18-0.61] and HR = 0.46, p < .001 [95% CI = 0.29-0.72]). Among mothers in the BSP group there was on average 66% less risk of cessation of any breastfeeding and on average 54% less risk of cessation of exclusive breastfeeding at any point in time compared to those in the control group.
The BSP appears to be an effective means to delay cessation of any and exclusive breastfeeding cessation and therefore to increase breastfeeding duration and exclusivity. This is an important finding, because earlier cessation of breastfeeding than desired is a common problem in many countries. Future research into the effectiveness of the BSP could consider random assignment to conditions and test the effectiveness of the intervention in other populations to investigate further whether wide-scale implementation of this intervention could be useful to promote breastfeeding.
母乳喂养对婴儿和母亲都有重要的积极的长期健康影响。世界卫生组织建议所有婴儿应在六个月或更长时间内进行纯母乳喂养,并建议母乳喂养持续两年或以上。然而,许多国家并没有达到这些建议。本研究旨在探讨一项全面的、基于证据的母乳喂养干预措施——母乳喂养支持计划(BSP),是否能促进参与者延长母乳喂养时间并提高母乳喂养的纯母乳喂养率。
采用准实验设计,比较 BSP 组(n=66)和对照组(n=72)的母乳喂养持续时间和纯母乳喂养率。参加 BSP 的参与者接受了由哺乳顾问提供的 6 次咨询。咨询从怀孕开始,一直持续到产后 10 周。对照组的参与者不遵循 BSP。通过互联网进行预测试和后测试问卷调查。使用 Cox 比例风险回归分析来估计调整后的危险比(HR)和 95%置信区间(CI),以控制基线差异,用于任何形式和纯母乳喂养的停止。
在控制两组基线差异的情况下,BSP 对任何形式和纯母乳喂养的生存率的影响是显著的(分别为 HR=0.34,p<0.001[95%CI=0.18-0.61]和 HR=0.46,p<0.001[95%CI=0.29-0.72])。在 BSP 组中,与对照组相比,任何形式的母乳喂养停止的风险平均降低了 66%,纯母乳喂养停止的风险平均降低了 54%。
BSP 似乎是一种有效的方法,可以延迟任何形式和纯母乳喂养的停止,从而延长母乳喂养的时间和纯母乳喂养率。这是一个重要的发现,因为在许多国家,过早停止母乳喂养比预期的更为常见。未来对 BSP 有效性的研究可以考虑随机分配条件,并在其他人群中测试干预措施的有效性,以进一步调查这种干预措施的广泛实施是否有助于促进母乳喂养。
