Variables
SECONDARY
Outcomes assessed in this study were poultry ownership, egg production, poultry vaccination and poultry shed use, which were prespecified pathway indicators of the trial. We then examined women's and children's egg consumption, which were pre‐specified secondary outcomes of the trial. All outcomes were assessed at the individual level. Poultry production was measured with two dichotomous and one continuous variable: ownership of any poultry (chickens or ducks), ownership of at least three poultry—the minimum target promoted by the FAARM intervention, and the number of poultry owned—capped at 95 chickens and ducks to reduce the influence of outlying larger‐scale poultry operations (<0.5% of all households in each of the three surveillance rounds). Egg production was assessed as the number of eggs produced per week, capped at 95 eggs, and as two dichotomous variables: production of at least one egg in the last week and at least seven eggs in the last week. Vaccination was assessed with two dichotomous variables: whether poultry were ever vaccinated and whether they were vaccinated in the prior 6 months. Poultry shed use was measured by three dichotomous variables: whether households owned a poultry shed, whether the shed was actively used for poultry, and whether they owned an ‘improved’ poultry shed. To evaluate egg consumption, dichotomous variables were created based on whether children consumed any egg and whether women consumed at least 15 g of egg (about one‐third of an egg) in the past 24 h.Covariates included household religion, household wealth quintile at baseline, woman's education, child sex and age, month of survey and whether the day of recall occurred during Ramadan. A household wealth index was calculated using principle components analysis of household assets in line with standard demographic and health survey (DHS) techniques (Rutstein & Johnson,
