  1. The outcome variable is in (1) and (2) the SF12 measure computed on the first factor loading and in (4) and (5), the SF12 measure computed on the second factor loadings for the Malawian population. In columns (2) and (4), are the standardised beta-coefficients presented. Model (1) presents findings from the analysis on the 2006 sample. Model (2) presents findings from the analysis on the 2012/13 sample. We control for year and region effects, and covariates. Robust standard errors in parentheses; *** p < 0.01, ** p < 0.05, * p < 0.1
