This study examines how prevalence and clustering of cardiovascular disease (CVD) risk factors differ by ethnicity and socioeconomic status (SES) among rural southwest Chinese adults.
A cross-sectional survey of 7027 adults aged ≥35 years of Han and four ethnic minority group descent (Na Xi, Li Shu, Dai, and Jing Po) was used to derive prevalence of tobacco smoking and exposure to secondhand smoke (SHS) as well as alcohol consumption and physical activity data. Anthropometric measurements were also taken, including height, weight, and waist and hip circumference, as well as blood pressure (BP) and fasting blood glucose (FBG) measurements.
Current smoking and drinking status were the top two CVD risk factors in the study population. Dai ethnic minority participants had the highest prevalence of hypertension, obesity, and central obesity, whereas Jing Po ethnic minority participants had the highest prevalence of current smoking status, SHS exposure, and current drinking status (P < 0.01). Han participants had the highest prevalence of diabetes and physical inactivity (P < 0.01). 11.1% of all participants did not have any of the studied CVD risk factors, while 68.6% of Han, 60.2% of Na Xi, 50.7% of Li Shu, 82.2% of Dai, and 73.0% of Jing Po participants had clustering of two or more CVD risk factors. Prevalence of CVD risk factor clusters increased with age (P < 0.01). Males and individuals with lower education levels and lower annual household income were more likely to have CVD risk factors than their counterparts (P < 0.01).
Clustering of CVD risk factors is common in rural southwest China. Ethnicity and individual SES significantly impact prevalence of CVD risk factors and their clustering.
本研究旨在探讨中国西南部农村地区成年人中，心血管疾病（CVD）风险因素的流行情况和聚集程度在不同种族和社会经济地位（SES）之间的差异。
本研究采用横断面调查方法，对 7027 名年龄≥35 岁的汉族和四个少数民族（纳西族、傈僳族、傣族和景颇族）成年人进行调查，以获取吸烟和二手烟暴露、饮酒和体力活动等 CVD 风险因素的流行情况。还进行了人体测量学测量，包括身高、体重、腰围和臀围，以及血压（BP）和空腹血糖（FBG）测量。
在研究人群中，当前吸烟和饮酒状况是前两个 CVD 风险因素。傣族参与者的高血压、肥胖和中心性肥胖患病率最高，而景颇族参与者的当前吸烟状况、二手烟暴露和当前饮酒状况的患病率最高（P<0.01）。汉族参与者的糖尿病和体力活动不足的患病率最高（P<0.01）。所有参与者中有 11.1%没有任何研究的 CVD 风险因素，而汉族、纳西族、傈僳族、傣族和景颇族参与者中，分别有 68.6%、60.2%、50.7%、82.2%和 73.0%存在两个或更多 CVD 风险因素的聚集。CVD 风险因素聚集的患病率随着年龄的增加而增加（P<0.01）。男性和受教育程度较低、家庭年收入较低的个体比同龄人更容易出现 CVD 风险因素（P<0.01）。
CVD 风险因素的聚集在中国西南部农村地区很常见。种族和个体 SES 显著影响 CVD 风险因素的流行情况及其聚集程度。
