郑州市卒中及其常见危险因素城乡流行现状对比

目的 研究郑州市40岁以上人群卒中患病率及其常见危险因素的城乡流行现状。 方法 以社区为基本单位进行整群抽样，纳入符合要求的郑州市40岁以上常住人口11 366例，采集 人口学、卒中危险因素、既往用药、体格检查和实验室检查等信息，用单因素和多因素Logistic回归分 析卒中及其常见危险因素的城乡差异。 结果 从2013年12月至2014年3月共纳入11 366例社区居民，其中卒中患者344例，卒中标化患病率农 村高于城市（3.3% vs 2.5%，Z =-2.649，P =0.004），逐步调整各项影响因素后，卒中的患病率与居 住地为农村呈正相关（OR 1.77，95%CI 1.31～2.38）。心房颤动、明显超重或肥胖、缺乏运动和既往发 生过短暂性脑缺血发作的比例农村低于城市（P <0.001），吸烟比例农村高于城市（P <0.001）。 结论 郑州市卒中及其危险因素的城乡差异显著，卒中防控工作应当针对当地卒中防控的薄弱环节， 制订更有针对性的卒中社区防治策略。

Comparison of the Prevalence of Stroke and Its Common Related Risk Factors between Urban and Rural Areas in Zhengzhou

Objective To investigate the epidemiological characteristics of stroke and its common related risk
factors among the urban and rural population aged above 40 years old in Zhengzhou.
Methods Using cluster sampling method in community-unit, a total of 11 366 inhabitants over
40 years old in Zhengzhou were recruited. The collected information covered basic individual
information, related risk factors, past medicine information, physical and laboratory examinations.
Single factor analysis and multiple logistic regression analysis were used to compare the prevalence
of stroke and related risk factors between urban and rural areas based on the information including
demographic data, risk factors of stroke, past medication history, physician and laboratory
examinations, etc.
Results From December 2013 to March 2014, 11 366 cases over 40 years old in Zhengzhou were
involved in the study. The number of the patients with stroke was 344, and the standardized prevalence
rate of stroke in rural areas was significantly higher than that in urban areas (3.3% vs 2.5%, Z =-2.649,
P =0.004). After adjusted for the relevant influencing factors in a step-by-step manner, living in rural
areas was still positively associated with stroke (OR 1.77, 95%CI 1.31~2.38). The prevalence of atrial
fibrillation, overt overweight or obese, lack of exercises and previous transient ischemic attack in rural
areas was significantly lower than that in urban areas (P <0.001); and the prevalence of smoking in
rural areas was significantly higher than that in urban areas (P <0.001).
Conclusion There were significant differences of stroke and its risk factors in rural and urban areas
in Zhengzhou. The prevention and treatment work for stroke would be adapted to the strategy of
community prevention and treatment in allusion to the local weaknesses.
