Abstract

Background

Limited research exists on the specific approaches and behavior change techniques (BCT) used in nutrition-sensitive agriculture (NSA) programs and their effects on diet diversity.

Objectives

We aimed to describe nutrition-related social behavior change (SBC) in the context of NSA and quantify the effectiveness of different SBC components of NSA programs in improving diet diversity.

Methods

We searched PubMed, Embase, Web of Science, the International Food Policy and Research Institute repository, and Agricola for articles published between 2000 and 2023. We identified the agricultural activities each project used as a pathway to improved nutrition (ag-nutrition pathways), identified SBC approaches used by each project, and coded BCTs using validated coding protocols. Effectiveness ratios (ERs) were calculated to assess pathways, approaches, and BCTs in relation to dietary diversity outcomes (minimum diet diversity for children, child dietary diversity score, and women’s dietary diversity).

Results

Of 65 included NSA interventions, the most used agriculture-to-nutrition pathways included 1) agricultural production for home consumption (n = 61); 2) women’s empowerment (n = 36); and 3) agricultural income (n = 37) pathways. The most used SBC approaches were interpersonal communication (IPC, n = 59) and community-based approaches (n = 53). Frequently used BCTs included “instructions on how to perform the behavior” (n = 65), “social support (unspecified)” (n = 43), and using a “credible source” (n = 43). The increased production for the home consumption pathway, IPC approach, and the BCT “behavioral practice” had high ERs for diet diversity outcomes.

Conclusions

Although the agricultural production for home consumption pathway to improved nutrition had the highest ERs for diet diversity, other pathways, such as income generation and reducing wastage, hold promise and require additional investigation. The most commonly applied BCTs focused on information dissemination; however, participatory BCTs related to behavioral demonstration, and behavioral practice had higher ERs. Findings indicate a need to test less frequently utilized SBC components to determine effectiveness.

营养敏感型农业项目中社会行为改变活动要素的有效性:系统回顾。
背景关于营养敏感型农业(NSA)项目中使用的具体方法和行为改变技术(BCT)及其对膳食多样性影响的研究有限。方法我们检索了 PubMed、Embase、Web of Science、国际粮食政策与研究所资料库和 Agricola 中 2000 年至 2023 年间发表的文章。我们确定了每个项目作为改善营养途径(农业营养途径)所使用的农业活动,确定了每个项目所使用的 SBC 方法,并使用经过验证的编码协议对 BCT 进行了编码。结果 在纳入的 65 个 NSA 干预项目中,使用最多的农业营养途径包括:1)供家庭消费的农业生产(n = 61);2)妇女赋权(n = 36);3)农业收入(n = 37)途径。使用最多的 SBC 方法是人际传播(IPC,n = 59)和基于社区的方法(n = 53)。经常使用的 BCT 包括 "指导如何实施该行为"(n = 65)、"社会支持(未指定)"(n = 43)和使用 "可信来源"(n = 43)。为家庭消费增加产量的途径、IPC方法和BCT "行为实践 "对膳食多样性结果的ER值较高。结论虽然为家庭消费增加产量的农业营养改善途径对膳食多样性的ER值最高,但其他途径,如创收和减少浪费,仍有希望,需要进一步调查。最常应用的业连试侧重于信息传播;然而,与行为示范和行为实践有关的参与性业连试的ER值较高。研究结果表明,有必要对使用频率较低的SBC组成部分进行测试,以确定其有效性。该试验已在PROSPERO(=https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=179016)上注册,编号为CRD42020179016。
