The objective of this study was to test whether adding a text message campaign about the importance of eating eggs and other nutrition-related behaviours to an on-going package of large-scale, diverse social and behaviour change interventions would improve four types of nutrition-related knowledge and behaviour outcomes: child diets (egg consumption as the primary outcome), maternal diets, maternal nutrition knowledge, and maternal participation in additional interventions. The cluster-randomized controlled trial involved a repeat cross-sectional design, recruiting families with children 12-23 months of age at baseline and endline in one plains district of Nepal. Throughout the 1000-day period, 51 text messages were sent to each household at specific time points to reinforce ideal diets and other nutrition-related practices and promote engagement with community health workers and other intervention platforms. The primary outcome was egg consumption and dietary diversity among young children. We found no population-level effect. Some evidence supports that for those who received and opened the SMS intervention, it improved child egg consumption (odds ratio [OR]: 1.41, 95% confidence interval [CI]: 1.03-1.93), child minimum dietary diversity (OR: 1.36, 95% CI: 1.07-1.73), child dietary diversity scores (β: 0.15, 95% CI: 0.01-0.24), as well as maternal IYCF knowledge (β: 0.21, 95% CI: 0.08-0.35), participation in health mothers' group meetings (OR: 3.03, 95% CI: 1.91-4.84) and Bhanchhin Aama listenership (OR: 1.36, 95% CI: 1.07-1.73). This study highlights the importance of more research to understand the effectiveness of emerging digital interventions for behaviour change among specific populations, to facilitate nuanced targeting to those who can best benefit from these investments.

本研究的目的是测试，在一系列正在进行的大规模、多样化社会和行为改变干预措施中，加入一项关于食用鸡蛋的重要性及其他营养相关行为的短信宣传活动，是否会改善四类营养相关知识和行为结果：儿童饮食（以鸡蛋消费为主要结果）、孕产妇饮食、孕产妇营养知识以及孕产妇参与其他干预措施的情况。这项整群随机对照试验采用重复横断面设计，在尼泊尔一个平原地区招募了基线期和终期时孩子年龄在12至23个月的家庭。在整个1000天期间，在特定时间点向每户发送51条短信，以强化理想饮食和其他营养相关做法，并促进与社区卫生工作者及其他干预平台的互动。主要结果是幼儿的鸡蛋消费和饮食多样性。我们未发现总体人群层面的效果。一些证据表明，对于那些接收并打开短信干预的人，该干预改善了儿童鸡蛋消费（优势比[OR]：1.41，95%置信区间[CI]：1.03 - 1.93）、儿童最低饮食多样性（OR：1.36，95% CI：1.07 - 1.73）、儿童饮食多样性得分（β：0.15，95% CI：0.01 - 0.24），以及孕产妇婴幼儿喂养和儿童营养知识（β：0.21，95% CI：0.08 - 0.35）、参与健康母亲小组会议（OR：3.03，95% CI：1.91 - 4.84）和收听“Bhanchhin Aama”广播（OR：1.36，95% CI：1.07 - 1.73）的情况。本研究强调了开展更多研究以了解新兴数字干预措施对特定人群行为改变有效性的重要性，以便更精准地面向那些能从这些投资中最大程度受益的人群。在clinicaltrials.gov上注册，标识符为NCT03926689。
