ABSTRACT
Objective: To explore the prevalence and risk factors of mitral regurgitation (MR) in the population ≥35 years in China in order to provide prevention reference for high risk crowd. Methods: The residents ≥35 years were taken by a stratified multistage sampling method. General information of crowd was collected by predesigned questionnaire and physical examination including life style, disease history, body weight and height. Echocardiography was conducted, fasting blood glucose and blood lipid levels were measured. Results: A total of 28814 subjects were enrolled. The overall MR detection rate was 18.4%, the detection rate in male and female were both 18.4%. The detection rates of moderate and severe MR were 0.3% in the paticipants at (35-50) years, 0.9% at (51-64) years and 2.2% at ≥65 years. MR prevalence showed an increasing trend with aging. Multivariate Logistic regression analysis indicated that age, systolic blood pressure, urban and rural, district, left atrial front and back diameter, left ventricular end diastolic front and back diameter, left ventricular ejection fraction, stroke, atrial fibrillation and heart failure were the risk factors for MR occurrence. Conclusion: MR detection rate was rather high in China. Specific prevention action should be taken for those with theabove risk factors.
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 factors:hypertension,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.
ABSTRACT
Objective To investigate the association between types of obesity and the 10-year-coronary heart disease risk in Tibet and Xinjiang of China.Methods Using the multi-stage random sampling method,7 631 participants aged 35 or older were examined under the International Standardized Examination process but with only 5 802 were eligible for analysis,in the 2015-2016 season.Results The prevalence rates of general obesity,central obesity,visceral obesity and compound obesity were 0.53％,12.62％,10.08％ and 42.35％,respectively.Out of all the compound obesity cases,58.65％ (1 441/2 457) of them appeared as having all types of obesity in our study.Risk related to the 10-year-coronary heart disease was higher in men than in women [(3.05 ± 4.14)％ vs.(1.42-2.37) ％,P＜0.000 1.Compound obesity (30.16％) showed the highest proportion on the risk of 10-year-coronary heart disease than central obesity (28.01％),visceral obesity (18.46％) or the general obesity (19.35％).After adjustment for confounding factors,results from the multivariate analysis showed the risk in compound obesity was higher than central obesity,visceral obesity or general obesity and was associated with the highest risk on the 10-year-coronary heart disease (OR=2.889,95％CI:2.525-3.305).People with anomalous BMI and WC seemed to have had the higher risk (OR=3.168,95％CI:2.730-3.677).Conclusions Obesity was popular in the residents of Tibet and Xinjiang areas of China.Men and people with compound obesity (especially both BMI and WC were abnormal) seemed to carry greater risk on the 10-year-coronary heart disease.
