Abstract
Context: Achieving adequate nutrition for vulnerable populations is central to the second Sustainable Development Goal. Nutrition-sensitive social-protection programs combined with social and behavior change communication (SBCC) interventions can support this goal, particularly in developing countries. However, systematic evidence on the impact of integrating SBCC strategies into these programs is limited, especially concerning anthropometric outcomes, dietary diversity, food consumption, and food security.
Objective: This systematic review aimed to assess the importance of integrating SBCC interventions into nutrition-sensitive social-protection programs for optimal nutritional outcomes.
Data sources: PubMed, Web of Science, EMBASE, ScienceDirect, and Google Scholar databases were searched for original research articles before December 2024.
Data extraction: A total of 15 publications, involving data from multiple households, mothers, and children, were identified. All extracted data were compiled, compared, and critically analyzed.
Data analysis: The review included 7 randomized controlled trials, 5 cluster-randomized trials, and 3 descriptive studies. Most studies demonstrated significant improvements in maternal and child dietary diversity, household food consumption, and minimum meal frequencies. Knowledge and practices around exclusive breastfeeding and complementary feeding also improved substantially. Among children, stunting, wasting, and underweight prevalence decreased significantly, with effect sizes indicating meaningful public health impacts. However, the sustainability of these outcomes depended on the follow-up duration. Notably, none of the included studies exhibited a high risk of bias, reinforcing the reliability of the findings.
Conclusion: Integrating SBCC into nutrition-sensitive social-protection programs is effective in achieving clinically significant nutritional outcomes for vulnerable populations. While the findings suggest sustained benefits, further research is needed to determine optimal entry points, effective messaging, advocacy strategies, and communication channels. This is particularly critical for lower-and middle-income countries, where malnutrition remains a critical challenge.
背景:为弱势群体提供充足营养是第二个可持续发展目标的核心。营养敏感型社会保护计划与社会和行为改变沟通(SBCC)干预措施相结合,可以支持这一目标,特别是在发展中国家。然而,将SBCC策略纳入这些计划的影响的系统证据有限,特别是在人体测量结果、饮食多样性、食物消费和粮食安全方面。目的:本系统综述旨在评估将SBCC干预措施纳入营养敏感型社会保护计划以获得最佳营养结果的重要性。数据来源:检索PubMed、Web of Science、EMBASE、ScienceDirect和谷歌Scholar数据库,检索2024年12月前的原创研究文章。数据提取:共确定了15份出版物,涉及多个家庭、母亲和儿童的数据。对所有提取的数据进行汇编、比较和批判性分析。资料分析:纳入7项随机对照试验、5项集群随机试验和3项描述性研究。大多数研究表明,在孕产妇和儿童饮食多样性、家庭食物消费和最低进餐频率方面都有显著改善。有关纯母乳喂养和补充喂养的知识和做法也大大改善。在儿童中,发育迟缓、消瘦和体重不足的患病率显著下降,其效应量表明对公共卫生产生了重大影响。然而,这些结果的可持续性取决于随访时间。值得注意的是,纳入的研究中没有一项显示出高偏倚风险,这加强了研究结果的可靠性。结论:将SBCC纳入营养敏感型社会保护计划,可以有效地为弱势群体实现具有临床意义的营养结果。虽然研究结果显示了持续的好处,但需要进一步的研究来确定最佳切入点、有效的信息传递、倡导策略和沟通渠道。这对低收入和中等收入国家尤其重要,在这些国家,营养不良仍然是一项重大挑战。系统评审注册:普洛斯彼罗注册号。CRD42023452510。
