Abstract: Objective　To understand the prevalence of hypertension and health-related behaviors among floating population in a city in Shandong Province with factor analysis of health-related behaviors in order to provide a scientific basis for the effective prevention and control of hypertension and its policies of floating population.Methods　Using the multi-stage sampling method in 2015，three counties/districts were selected randomly in a city of Shandong Province according to their economic level（good，medium，poor），and each county/district randomly selected six communities/villages.Around 100 floating people aged 18 or older were randomly selected in each community/village.A total of 1 705 questionnaires were distributed，and the recovery rate was 100.00%.Questionnaire surveys and physical examinations were conducted among selected subjects to collect their basic information，health-related behaviors，and information on the prevalence of hypertension.Descriptive analysis and factor analysis were performed by SPSS 17.0 software.Results　The prevalence of hypertension among floating population in a city of Shandong Province was 8.97%（153/1 705）.c2 value of Bartlett's test was 3 223.347 with the probability value <0.01，and KMO value was 0.590，which was suitable for factor analysis.A total of 10 common factors were extracted（the cumulative contribution rate was 59.524%）.F1 was named as medical satisfaction（the variance contribution rate was 7.967%）；F2 was named as the choice of medical institutions（the variance contribution rate was 7.933%）；F3 was named as dietary rules（the variance contribution rate was 6.652%）；F4 was named as psychological factors（the variance contribution rate was 6.470%）；F5 was named as passive smoking（the variance contribution rate was 5.647%）；F6 was named as sleep status（the variance contribution rate was 5.628%）；F7 was named as eating habits（the variance contribution rate was 5.349%）；F8 was named as diet mix（the variance contribution rate was 4.814%）；F9 was named as medical security（the variance contribution rate was 4.567%）；F10 was named as active smoking（the variance contribution rate was 4.496%）.Among them，the top four influencing factors of health-related behaviors were medical satisfaction，the choice of medical institutions，dietary rules，and psychological factors.Conclusion　The prevalence of hypertension in the floating population is 8.97%.Influencing factors of health-related behaviors related to hypertension include medical satisfaction，the choice of medical institutions，dietary rules，psychological factors，and so on.Therefore，in order to reduce the prevalence of hypertension among floating population，medical institutions need to improve their medical technology and service quality，and floating people need to balance their diet and pay attention to their psychological issues to change their health-related behaviors.

摘要： 目的　了解山东省某市流动人口高血压患病状况和健康相关行为，对健康相关行为进行因子分析，为流动人口高血压有效防控和政策措施的研究提供科学依据。方法　于2015年采用多阶段抽样方法，按经济水平好、中、差在山东省某市随机抽取3个县（区），每个县（区）随机抽取6个社区（村），每个社区（村）随机抽取100例左右年龄≥18周岁的流动人口作为调查对象。本研究共发放问卷1 705份，回收有效问卷1 705份，有效率为100.00%。对入选的对象进行问卷调查和体格检查，收集其基本情况、健康相关行为、高血压患病情况。采用SPSS 17.0软件进行描述性分析和因子分析。结果　山东省某市流动人口高血压患病率为8.97%（153/1 705）。Bartlett's球形检验c2值为3 223.347，P<0.01，KMO值为0.590，适合进行因子分析。共提取出10个公因子（累积方差贡献率为59.574%），F1命名为就医满意度（方差贡献率为7.967%）、F2命名为就诊机构选择（方差贡献率为7.933%）、F3命名为饮食规律（方差贡献率为6.652%）、F4命名为心理因素（方差贡献率为6.470%）、F5命名为被动吸烟（方差贡献率为5.647%）、F6命名为睡眠状况（方差贡献率为5.628%）、F7命名为饮食习惯（方差贡献率为5.349%）、F8命名为饮食搭配（方差贡献率为4.814%）、F9命名为医疗保障（方差贡献率为4.567%）、F10命名为主动吸烟（方差贡献率为4.496%）。其中占比较大的前4位健康相关行为影响因素依次是就医满意度、就诊机构选择、饮食规律、心理因素。结论　流动人口高血压患病率为8.97%，患病的健康相关行为影响因素包括就医满意度、就诊机构选择、饮食规律、心理因素等，因此医疗机构需提高医疗技术水平和医疗服务可及性，流动人群需平衡饮食，重视心理问题，改变其健康相关行为，降低高血压患病率。
