In the origin study, the definition may stratify mortality risks in people who are overweight or normal weight. We aimed to investigate the association between the new MH definition and all-cause mortality in a nonobese Chinese population.<h4>Methods</h4>The data were collected in 1992 and then again in 2007 from the same group of 1157 participants. The association between the new MH definition and all-cause mortality were analyzed by Cox regression models with overlap weighting according to propensity score (PS) as primary analysis.<h4>Results</h4>At baseline in 1992, 920 (79.5%) participants were categorized as MH, and 237 (20.5%) participants were categorized as metabolically unhealthy (MUBMC public healthNew metabolic health definition might not be a reliable predictor for mortality in the nonobese Chinese population.PMC9422146Z201920102017YFC09100042006BAI01A0122ZDYF152785-915-01-02He SRuan HHe YZhu YZhang MWei XChen XWei JWang ZLi LfalseNew metabolic health definition might not be a reliable predictor for mortality in the nonobese Chinese population.<h4>Background</h4>Recently, a new metabolic health (MH) definition was developed from NHANES-III.
