Contribution of home garden vegetables on reducing stunting among 6- to 23-month-old children in South Tigray, northern Ethiopia.

Abstract

The study was conducted to analyze the contribution of home garden vegetables in reducing stunting among 6- to 23-month-old children from South Tigray, Northern Ethiopia. The quasi-experimental study design was used. Multistage sampling technique was used to select the districts and study communities. A total of 94 purposively selected vegetable producer (intervention) households and 260 randomly selected non-producer (control) households were included in the study (1:3 ratio). The recumbent length of children was measured using horizontal wooden board to the nearest 0.1 cm. The length-for-age Z-scores were computed using WHO-Anthro 2006 software. Propensity score-matching and difference-in-difference (DID) estimates were used to analyze data using STATA software version 12. Prevalence of child stunting was 19.8 (12.7-29.4) and 21.1 (16.4-26.7)% (baseline) and 43.5 (33.5-54.1) and 46.5 (45.7-47.2)% (end line) among intervention and control groups, respectively. Child stunting was higher for boys and older children from both intervention and control households. DID estimation revealed that there was no significant difference in child stunting between intervention and control households (DID = 1.7, p = .604). However, there was an intervention effect of -0.5, 2.5, and 1.7% in the prevalence of child stunting among females, males, and both sexes, respectively. Vegetable production as an intervention strategy reduced the prevalence of stunting in children aged 6-23 months. However, vegetable production needs to be well integrated with other nutrition-sensitive interventions to realize the objective of reducing child stunting.
