The problem
Intervention: Access to and purchasing of food from supermarkets rather than traditional markets
Who it was tested with: Children in urban Kenya.
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.
"panel data from urban Kenya" and measurement of child nutritional outcomes (height-for-age, weight-for-age, weight-for-height Z-scores) indicates a longitudinal observational design tracking the same children over time, which is stronger than cross-sectional but lacks randomization, making it an experimental tier study that can identify associations and trends in a defined population.
Panel data study design; limited to urban Kenya; cross-sectional associations may reflect selection bias (healthier households may preferentially shop at supermarkets); cannot determine causality definitively or identify specific nutrients or foods responsible for improvements.
