Association between body fat percentage, visceral fat index and cardiometabolic risk factor clustering among population aged 35 year old or over, in Tibet Autonomous Region and Xinjiang Uygur Autonomous Region / 中华流行病学杂志

ABSTRACT

Objective To investigate the association between body fat percentage (BFP),visceral fat index (VFI) and Cardiometabolic Risk Factor Clustering (CRFC),among population aged 35 or older in Tibet and Xinjiang areas.Methods Using the stratified multi-stage random sampling method,7 571 residents aged 35 or above were examined with international standardized examination between 2015 and 2016.Of the eligible 5 643 participants,association of BFP and VFI with CRFC was defined as having two or more of the four risk factorshypertension,diabetes mellitus,high TG and low HDL-C,at the same time.Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were employed to further explore the relationships.Results The overall prevalence of CRFC among aged 35 and older population in Tibet and Xinjiang areas was 9.78％.BFP and VFI were divided into four groups by quartile.After adjustment for age,gender,race,cigarette smoking,alcohol consumption,education attainments,and altitude of residence,ORs of CRFC seemed to have increased with BFP and VFI.Compared with people having BFP of 5.0％-27.0％,the OR(95％CI) were 1.15(0.86-1.54),1.48(1.05-2.07) and 1.72(1.10-2.68) for the ones who presented 27.1％-31.7％,31.8％-36.6％ and 36.7％-50.0％ of BFP.Compared to people of having 1-6 of VFI,with OR (95％CI) as 1.20(0.81-1.79),1.91(1.30-2.80) and 3.91(2.64-5.77) for the ones having 7-9,10-13 and 14-30 of VFI.Areas under the curve (AUC) of CRFC appeared as 0.55 for BFP and 0.70 for VFI,respectively,with statistically significant difference (P＜0.01).Conclusion Both BFP and VFI levels were closely associated with CRFC while VFI seemed to have a better predictive value than the BFP.
