The problem
Intervention: Livestock ownership in households with children aged 6-59 months
Who it was tested with: 3,438 children aged 6-59 months in Rwanda, with sub-analysis of Eastern Province and Nyagatare district.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Using Demographic and Health Survey (DHS) data from 3438 children aged 6–59 months and employing a multilevel mixed effects model, we investigate these interrelationships nationally, then focus on the Eastern Province and Nyagatare district"; the study used existing survey data with statistical modeling to examine associations between household livestock ownership and child nutritional status, measuring outcomes at a single time point without experimental manipulation of the exposure.
Observational design with no comparison group assigned by researchers; cross-sectional data prevents causal inference; unable to isolate the specific mechanism through which livestock ownership benefits child nutrition; potential for unmeasured confounding by economic status or other household factors not captured in the DHS.
