Cardiovascular disease outcomes in metabolically healthy obesity in communities of Beijing cohort study

摘要

Summary Objective The objective of this study was to investigate the association between metabolically healthy obese ( MHO ) phenotype and the risk of cardiovascular disease ( CVD ). Methods A total of 9393 subjects aged ≥40?years were enrolled in the cohort study (2011‐2015). The participants were stratified by body mass index category and metabolic risk at baseline, and incidence of CVD was ascertained at follow‐up. Results The MHO accounted for 6.7%. Compared with the metabolically healthy normal weight ( MHNW ) group, MHO subjects demonstrated increased risk of CVD events ( HR ?=?1.91; 95% CI , 1.13‐3.24). In people with obesity, there was no significant difference on increasing risk of incidence of CVD in the metabolically unhealthy individuals compared with metabolically healthy individuals ( HR ?=?1.19; 95% CI , 0.74‐1.91). Female ( OR ?=?1.97; 95% CI , 1.06‐3.64), smoking ( OR ?=?2.09; 95% CI , 1.06‐4.10), a larger waist circumference ( OR ?=?1.07; 95% CI , 1.03‐1.10) and higher LDL cholesterol levels ( OR ?=?1.55; 95% CI , 1.20‐2.00) were independent risk factors of the development of the MHO to the metabolically unhealthy obese ( MUO ) phenotype. Conclusions The risk of CVD events of MHO phenotypes is similar to MUO phenotypes; both are higher than the MHNW phenotypes.
