  1. BMI, body mass index; MUAC, mid upper arm circumference. aThe Household Hygiene Score is an objective measure of the living conditions of each participant and ranges from 0 (worst) to 10 (best). Trained fieldworkers score up to 2 points in each of five categories (overall cleanliness; water storage facilities; food storage facilities; hand washing facilities and their use; sanitation facilities) [2]. bOne case of night blindness in both groups. cFat and water content was measured using a Bodystat 1500 impedance analyser (Bodystat, Douglas, Isle of Mann). dDynamometry was measured using a Takeida dynamometer. eData available in 7/9 patients. fData available in 19/20 patients. gData available in 18/20 patients. hData available in 3/6 patients. iData available in 16/18 patients. j2-tailed t test. kFisher exact test. lChi squared test for trend. mChi squared test. nKruskal-Wallis test.
