Objective:To investigate the prevalence of metabolically healthy obesity(MHO)and its relationship with incidence of metabolic syndrome(MetS),type 2diabetes mellitus(T2DM)and hypertension in individuals in the city of Yulin.Methods:We studied 1,666 participants,aged over18years at baseline,with free of components of the MetS except waist criteria.Participants were divided into three groups based on body mass index(Ibm):lean/normal weight(Ibm<23kg/m2),overweight(Ibm,23-24.9kg/m2),obesity(Ibm≥25 kg/m2).The cumulative incidence of MetS,T2DM and hypertension over 5.21years among groups was assessed.Results:The prevalence of MHO was 19.5%in the baseline population.During an average 5.21year follow-up,the cumulative incidence of MetS,T2DM and hypertension in1,666participants were 16.4%,19.1%and 3.9%,respectively.The obesity group had a significantly higher cumulative incidence of MetS(16.4%vs.3.2%,P<0.001),hypertension(19.1%vs.3.7%,P<0.001),and T2DM(3.9%vs.1.6%,P<0.001)compared to the lean/normal weight group.Each kg/m2 of Ibm carried increased risk for T2DM(19%),hypertension(11%)and MetS(13%).Conclusion:Metabolically healthy obesity individuals confer increased risk for hypertension,T2DM and the MetS than their non-obese counterparts.
