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.
