简要总结
This complex evaluation of a large-scale program uses a cluster-randomized design where 20 geographic clusters (subdistricts) were randomized to study two sets of interventions. For the evaluation of behavior change interventions only, the 20 clusters were randomized to 10 intensive and 10 non-intensive interventions areas. For a sub-study to evaluate a market-based model for delivering micronutrient powders (MNP) along with behavior change interventions, there was subsequent randomization to comparison area, MNP-only area, Behavior Change Communication (BCC)-only area and MNP+BCC areas.
详细描述
The design uses a repeated cross-sectional design, with multiple age-group samples for multiple outcomes [since each set of outcomes can only be assessed in the relevant age group for the outcome; e.g., exclusive breastfeeding is only assessed in children 0-6 months of age]. These include:
- For the evaluation of behavior change intervention only:
- 0-6 months for breastfeeding outcomes
- 6-23.9 months for complementary feeding outcomes (in the behavior change intervention evaluation)
- 24-48 months for child anthropometric outcomes (related to the behavior change interventions).
- for the substudy on behavior change and micronutrient powder interventions combined - 6-23.9 months for anemia and anthropometric outcomes
A community-based random sample of children 0-6 months, 6-23.9 months, 24-48 months old was surveyed at baseline (April-June 2010). The original anemia sub-study design had proposed surveying children 6.23.9 months of age for the MNP intervention in April-June 2013 and for the behavior change intervention in April-June 2014. Based on program implementation timelines, the endline survey dates were extended by one year such that the above age groups were then sampled and surveyed in community-based surveys in April-June 2014.
Infant feeding practices will be assessed using before-after intervention-comparison area group differences between 2010, and 2013 and 2014. Specifically, breast feeding will be assessed in children 0-6 months of age (sampled separately) and complementary feeding will be assessed in children 6-23.9 months of age (sampled separately).

结局指标
主要结局
Exclusive breastfeeding (EBF) among children 0-6 months of age
时间窗: 4 years after baseline
EBF is among the eight WHO-recommended core indicators for infant and young child feeding and will be measured using recall-based survey measures
Complementary feeding among children 6-23.9 months of age
时间窗: 4 years after baseline
Complementary feeding indicators that include timely introduction of complementary feeding (infants 6-8 months), dietary diversity, minimum dietary diversity, minimum dietary diversity, are among the eight WHO-recommended core indicators for infant and young child feeding and will be measured using recall-based survey measures in this age group.
Child anthropometry (height, weight) among children 24-48 months of age
时间窗: 4 years after baseline
Child height and weight will be measured among the repeated cross-sectional of children living in the study villages. These will be converted into z-scores based on the WHO growth reference standards.
Anemia among children 6-23.9 months
时间窗: 4 years after baseline
Anemia will be measured using Hemocue
次要结局
- Iron deficiency(3 years)
