目的 探讨成都市高脂血症患病率及合并心血管危险因素的现状及城乡差异。 方法 2010年3月－11月随机抽样选取城市和农村社区，采用问卷、体格检查和实验室检查共调查35～70岁人群2 032例，其中城市社区1 015例，农村社区1 017例。进一步调查其中高脂血症患者合并的主要心血管危险因素。 结果 ① 成都市城乡高脂血症患病率为23.53%（474/2 032）。城市高于农村，分别为27.88%（283/1 015）和18.78%（283/1 017）；② 城市高脂血症人群中合并高血压、糖尿病和冠心病均高于农村。高脂血症合并高血压人群最多，城乡分别是51.95%（147/283）和31.94%（61/191），其次是合并“糖尿病”和“冠心病”人群；③ 城市高脂血症患者合并高血压人群无论男女均高于农村，但城市男性合并糖尿病者高于农村，城市女性合并冠心病者高于农村；④ 城乡高脂血症患者在合并饮酒、脑卒中史、腹型肥胖和肥胖之间差异无统计学意义（P＜0.05）。 结论 高血压、糖尿病和冠心病是城市高脂血症患者干预的重点危险因素。其中城市男性的糖尿病和城市女性冠心病干预更为重要。
Objective To investigate pre-hypertension in aspects of its incidence, accompanied cardiovascular risk factors, and difference between urban and rural areas in Chengdu. Methods By cluster random sampling method, a total of 2 011 patients aged 35-70 years from urban and rural communities in Chengdu were selected as respondents. The investigation was conducted through questionnaire, physical examination and laboratory tests, so as to find out the main cardiovascular risk factors of pre-hypertension. All data were dual input into computer by a specially-assigned person. SPSS 13.0 software was used for analysis, Chi-square test was adopted for categorical data, and Plt;0.05 was taken as an index for significant difference. Results a) The incidence rate of pre-hypertensive in Chengdu was 33.6%, and it was 45.67% and 46.31% in urban and rural areas, respectively. In rural area, more male (51.04%) were affected than female (42.83%). b) The smoking population with pre-hypertension were mainly the male, and the ratio of rural male was 60% (132/220), far higher than that of urban male which was 32.6% (59/181). c) The pre-hypertensive population accompanied with diabetes was higher in urban (27.97%) than rural (14.01%). d) The pre-hypertensive population accompanied with hypercholesterolemia or low HDL was 33.04% (150/454) in urban, as twice as that in rural which was 16.41% (76/471). e) The pre-hypertensive population accompanied with abdominal obesity was far higher in urban (28.41%) than rural (12.74%). Conclusion Smoking is the risk factor which needs to be primarily intervened for male hypertensive patients in rural area. Impaired glucose tolerance is the common risk factor for both urban and rural residents, and hyperlipidemia is the most primarily risk factor for urban pre-hypertensive patients, followed by diabetes, and abdominal obesity.
