MAHAY Study 2014, Baseline - Madagascar

Abstract
---------------------------

The MAHAY study uses a multi-arm randomized-controlled trial (RCT) to test the cost-effectiveness of combined interventions to address chronic malnutrition and poor child development. The arms of the trial are: (T0) existing community based nutrition program program with monthly growth monitoring and nutritional/hygiene education; (T1) is T0 + home visits for intensive nutrition counseling within a behavior change framework; (T2) is T1 + lipid-based supplementation (LNS) for children 6-18 months old; (T3) is T2 + LNS supplementation of pregnant/lactating women; and (T4) is T1 + intensive home visiting program to support child development.

Trial Registration: Current Controlled Trials ISRCTN14393738. Registered June 23, 2015.

Analysis unit
---------------------------

Pregnant women, children 0-12 months old and respective households

Universe
---------------------------

Target population: pregnant women and children eligible to attend the national community based nutrition program

Kind of data
---------------------------

Sample survey data [ssd]

Sampling procedure
---------------------------

Our sampling frame is the universe of community nutrition project sites in the target regions of the program. From this universe of project communities, we drew a sample of communities that was randomly assigned to five groups. The comparison group for our study is the program as currently designed (as opposed to no program in most of the evaluation literature). In the four randomized arms, we have sequentially added increasing levels of intensity and complexity to the current intervention, starting with the lowest cost option and incrementally adding layers of intensity (and cost) to test the value added of each layer in terms of their ability to reduce stunting/growth faltering and promote child development.

Mode of data collection
---------------------------

Computer Assisted Personal Interview [capi]

Research instrument
---------------------------

The following questionnaires were used for data collection
- questionnaire_acn_francais_v1
- questionnaire_enfant_francais_v2
- questionnaire_enfant_sans_asq_francais_v2
- questionnaire_menage_femme_francais_v2
- questionnaire_village_francais_v1
The questionnaires were administered in French and they are provided in pdf for download under the Documentation tab.

摘要
---------------------------
MAHAY研究采用多臂随机对照试验（RCT）来测试针对慢性营养不良和儿童发育不良的综合性干预措施的成本效益。试验的臂包括：（T0）现有的以社区为基础的营养计划，包括每月的生长监测和营养/卫生教育；（T1）在行为改变框架内增加家庭访问，进行强化营养咨询；（T2）为6-18个月大的儿童提供基于脂质的补充剂（LNS）；（T3）为怀孕/哺乳期妇女提供LNS补充剂；（T4）增加强化家庭访问计划以支持儿童发展。

试验注册：Current Controlled Trials ISRCTN14393738。注册日期：2015年6月23日。

分析单位
---------------------------
孕妇、0-12个月大的儿童及其家庭

总体
---------------------------
目标人群：符合国家社区营养计划资格的孕妇和儿童

数据类型
---------------------------
样本调查数据 [ssd]

抽样程序
---------------------------
我们的抽样框架是目标地区社区营养项目点的总体。从这一项目社区总体中，我们随机抽取了一部分社区分配到五个组中。我们研究的比较组是当前设计的计划（与大多数评估文献中的无计划相比）。在四个随机分配的臂中，我们依次增加了当前干预措施的强度和复杂性，从成本最低的选项开始，逐步增加强度（和成本）的层次，以测试每一层在减少生长迟缓和促进儿童发展方面的价值。

数据收集方式
---------------------------
计算机辅助个人访谈 [capi]
