A pre-post pilot study with and without subsidy to promote improved backyard poultry-raising practices to reduce exposure to poultry and poultry feces in rural Bangladesh
Randomized trial shows effective improvements in poultry management practices in rural households, indicating health benefits.
Key Points
This study aims to evaluate the impact of a subsidy on improving poultry-raising practices to reduce pathogen exposure in rural Bangladesh.
Conducted a two-arm (subsidy and non-subsidy) pre-post pilot study among 79 households in rural Bangladesh.
Administered household surveys and spot-checks at baseline and after intervention implementation.
Provided monetary subsidy for improved poultry shed construction to the subsidy arm households.
At endline, 58% of households had an improved poultry shed, with 87% in the subsidy arm.
Confining poultry outside at night rose significantly from 2.5% to 33% after the intervention (prevalence difference: 30pp; 95% CI: [19, 41]).
More households maintained a clean indoor living space, with no visible poultry feces inside compared to baseline (prevalence difference: 26pp; 95% CI: [10, 41]).
