HFIAS, Household Food Insecurity Access Scale; IDDS, Individual Dietary Diversity Score; MUAC, mid upper-arm circumference; β, standardized regression coefficient; t, robust t statistic; AOR, adjusted odds ratio.
(*) P < 0·10., *P < 0·05, **P < 0·01, ***P < 0·001
†The control variables included in the models were: age in years; sex; CD4 count (cells/μl); education; if the person is the head of the household or spouse of the household head; if the person is in a stable relationship; if the household lives in an internally displaced camp; household size; per capita total monthly household expenditures in tertiles; time to TASO (The AIDS Support Organization) clinic (min); distance to the nearest government hospital (km); distance to the nearest market (km); month and year of the interview; and a district dummy.
‡Wasting defined as MUAC <230 mm for males; <220 mm for females.
