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％CI2.525-3.305).People with anomalous BMI and WC seemed to have had the higher risk (OR=3.168,95％CI2.730-3.677).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.
