  1. BCAA: Branched-chain amino acids were adjusted for energy intake using the residual method;
  2. aModel was adjusted for age (in years, continuous), year of stay (≤4years, 5-9years, ≥10years), education (elementary and high school, college education and above), employment (no, yes), ever smoked (no, yes), current alcohol use (no, yes), energy intake (in kcal/d, continuous), history of diabetes (no, yes) and hypertension (no, yes);
  3. bInsufficient sample
