Methods The stratified sampling method was used to select elders with hypertension from 4 streets (townships) in urban and rural of Zhoushan in 2016. Four communities were selected from each street (townships) as sample units and using the random sampling to select 50 patients from every community. The investigation was performed with unified questionnaire. The influencing factors for self-efficacy were analyzed with logistic regression. Results The average score of the self-efficacy was 34.13±5.17. Among the investigated 738 elders with hypertension, more than half of them were scored 1ess than 2 in two items, which were blood pressure monitoring (86.99％) and persistent physical exercise (50.95％) . Scoring index of compliance behavior of hypertension was the lowest, only 63.93％ . By multivariate logistic regression analysis, those patients who were female (OR=2.34, 95％ CI 1.55-3.53) , educated (ORprimary=1.72, 95％ CI 1.09-2.69; ORjunior =2.25, 95％ CI 1.13-4.46;ORsenior and above=2.46, 95％ CI 1.06-5.71), with high level of drug compliance (ORmedium=1.72, 95％CI 1.09-2.69; ORhigh=2.12, 95％ CI 1.38-3.26) were more likely to get high level of self-efficacy. Patients who monitored blood pressure only uncomfortable were more likely to get low level of self-efficacy (OR=0.22, 95％ CI 0.08-0.68) . Conclusion More than half of community-dwelling elders with hypertension had a middle level self-efficacy in Zhoushan, who need further improvement. Corresponding interventions should be developed to strengthen the self-efficacy, which can help patients improve self-management of hypertension and establish a healthy life style.
