We examined independent influences of contextual variables on cardiovascular risk factors in Shilin county, Yunnan province, South-west China.
Three villages were selected from each of the ten townships based on probability proportional to size. In each selected village, 200 individuals aged > or = 45 years were chosen based on simple random sampling method. From 6006 individuals, information on demographic characteristics, smoking and drinking status was obtained by interview. Blood pressure, height, weight, and waist and hip girth were measured. Fasting blood sugar was measured in a 10-percent subsample. Contextual data were from official reports. Multi-level regression modelling with adjustment for individual and contextual variables was used.
Contextual variables associated with CVD risk factors included: remoteness of village with higher blood pressure and fasting blood sugar, high proportion of Yi minority with drinking, high literacy rate with a lower rate of smoking and a lower mean waist-hip ratio, and high average income with lower systolic blood pressure and body mass index (BMI) but higher FBS.
While contextual SES is associated with a few CVD risk factors, villages with high level of income are worse off in fasting blood sugar. Strategies of economic development should be reviewed to avoid adverse effects on health.
我们研究了中国西南部云南省石林县环境变量对心血管危险因素的独立影响。
根据规模比例概率从十个乡镇中各选取三个村庄。在每个选定的村庄中，采用简单随机抽样方法选取200名年龄≥45岁的个体。从6006名个体中，通过访谈获取人口统计学特征、吸烟和饮酒状况的信息。测量血压、身高、体重以及腰围和臀围。在10%的子样本中测量空腹血糖。环境数据来自官方报告。使用对个体和环境变量进行调整的多水平回归模型。
与心血管疾病危险因素相关的环境变量包括：村庄偏远与高血压和空腹血糖升高有关，彝族人口比例高与饮酒有关，识字率高与吸烟率较低和平均腰臀比降低有关，平均收入高与收缩压和体重指数（BMI）较低但空腹血糖较高有关。
虽然环境社会经济地位与一些心血管疾病危险因素相关，但高收入村庄的空腹血糖情况更差。应审查经济发展战略以避免对健康产生不利影响。
