HFIAS, Household Food Insecurity and Access Scale; HWISE, Household Water Insecurity Experience; PCA, principal component analysis; SES, socio-economic status.
Results from multivariable linear regression models with SE clustered on community and adjusting for community fixed effects (community coefficients not shown). The baseline model adjusts only for the community. Model 2 adds the PCA-derived SES score. Model 3 adds the covariates for age of female household head, number of children in household, number of times moved in the previous year and h/d spent collecting water
SES score was derived from the first component of a principal component analysis (PCA) conducted with ln(household monthly income+1), ln(livestock wealth+1) and average perceived social status score of household heads (ranging from 1 to 10).
