mNutrition Tanzania Endline Study

mNutrition was a five-year global initiative supported by the Foreign, Commonwealth & Development Office (FCDO) between 2013 and 2018, organized by GSM Association (GSMA), implemented by in-country mobile network operators, and evaluated by researchers from GAMOS, the Institute of Development Studies (IDS) and the International Food Policy Research Institute (IFPRI), with the objective of building effective mobile phone-based advisory services for improving nutrition outcomes. In Tanzania, mNutrition was implemented through the ‘Healthy Pregnancy, Healthy Baby’ (HPHB) SMS program and the service offered free customized health and nutrition information through pregnant women, mothers with newborns, and male supporters to promote good health-seeking behavior and improve knowledge and practices around optimal childcare and nutrition. To determine the causal effect of the program on nutritional outcomes, a cluster randomized control design was employed to randomly assign recipients to receive the messages. Household interviews were conducted before and after the intervention. Data collection was carried out in the three rural districts of the Iringa region: Iringa rural, Kilolo, and Mufindi. At the endline, 2595 households were interviewed of the 2,833 households at baseline. Interviews were conducted with both primary male and female members of the household.

mNutrition是一项为期五年的全球倡议，于2013年至2018年间由英国外交、联邦与发展事务部（Foreign, Commonwealth & Development Office, FCDO）资助，由全球移动通信系统协会（GSM Association, GSMA）统筹组织，各国本土移动网络运营商负责落地执行，并由来自GAMOS、发展研究所（Institute of Development Studies, IDS）以及国际粮食政策研究所（International Food Policy Research Institute, IFPRI）的研究人员开展评估，其宗旨为构建高效的移动手机端咨询服务，以改善营养健康结局。在坦桑尼亚，mNutrition项目通过"健康妊娠·健康婴儿"（Healthy Pregnancy, Healthy Baby, HPHB）短信计划实施，面向孕妇、新生儿母亲及男性支持者提供免费的定制化健康与营养信息服务，旨在推广积极的就医行为，并提升参与者在最优育儿与营养实践方面的认知与行为习惯。为明确该项目对营养健康结局的因果效应，研究采用整群随机对照试验设计，将服务对象随机分配以接收相关短信。干预措施实施前后均开展了家庭访谈。数据采集工作在伊林加（Iringa）地区的三个农村区县进行：伊林加农村、基洛洛（Kilolo）与穆芬迪（Mufindi）。在基线调查的2833户家庭中，终线调查共完成2595户家庭的访谈。访谈对象为家庭中的男性与女性主要成员。
