Abstract:
Objectives:To investigate the association between normal-weight central obesity with new-onset cardiovascular disease and all-cause mortality risk. Methods:A prospective cohort study was conducted,selecting a total of 93885 participants from the Kailuan Study who had their first physical examination in 2006-2007.According to waist circumference (central obesity:male waist circumference ≥90 cm,female waist circumference ≥85 cm;no central obesity:male waist circumference<90 cm,female waist circumference<85 cm) and body mass index (BMI,normal weight:18.5 kg/m2≤BMI<24.0 kg/m2;overweight/obesity:BMI ≥24.0 kg/m2),the participants were divided into 4 groups:normal weight no central obesity group (G1 group),normal weight central obesity group (G2 group),overweight/obesity no central obesity group (G3 group) and overweight/central obesity group (G4 group);Using the Kaplan-Meier method,the cumulative incidence of new-onset cardiovascular diseases (including hemorrhagic stroke,ischemic stroke and myocardial infarction) and all-cause mortality in different groups was calculated,and the Log-rank test was used for intergroup comparisons.Furthermore,the associations between the different groups and the risk of new-onset cardiovascular diseases and all-cause mortality were analyzed using the multivariate Cox proportional hazard regression model. Results:After a median follow-up of 14.97 (14.55,15.17) years,the cumulative incidence of new-onset cardiovascular diseases in G1 group,G2 group,G3 group and G4 group was 7.62%,10.84%,8.67%,12.91% respectively (log-rank P<0.05) and the cumulative incidence of all-cause mortality was 12.83%,19.72%,10.65%,16.33% respectively (log-rank P<0.01).After adjusting for confounding factors,Cox regression analysis showed that the HR (95%CI) of new-onset cardiovascular diseases in G2 group,G3 group and G4 group were 1.14 (1.04-1.25),1.07 (1.01-1.14),1.27 (1.21-1.34),respectively compared with G1 group (all P<0.05).The HR (95%CI) of all-cause mortality were 1.06 (1.00-1.14),0.90 (0.85-0.95),0.97 (0.93-1.01) compared with G1 group,and P values were 0.07,<0.01,0.15,respectively.The results of sensitivity analysis were consistent with the above major studies after excluding overweight/obesity and cancer participants during follow-up. Conclusions:Normal-weight central obesity increases the risk of new-onset cardiovascular diseases and all-cause mortality.
