  1. aBranched-chain amino acids were adjusted for energy intake using the residual method; IQR Interquartile range; Model 1 was adjusted for age (in years, continuous), year of stay (≤4years, 5-9years, ≥10years), education (elementary to high school, college education and above), employment (no, yes), ever smoke (no, yes), current alcohol use (no, yes) and energy intake (in kcal/d, continuous). Model 2 was adjusted for history of diabetes (no, yes) and hypertension (no, yes) in addition to variables in model 1
