Objective: To investigate the level of foot care behaviors of in patients with type 2 diabetes mellitus in Jinshan District of Shanghai, analyze the influential factors, and provide information for the intervention study. Methods: With convenient sampling method, a questionnaire survey was conducted with a sample of 110 inpatients with type 2 diabetes mellitus from Jinshan District of Shanghai. The investigation contents included patients′ demographic data, foot care knowledge and behaviors. The investigation tools were the questionnaire of diabetes general information, the questionnaire of foot care knowledge, and the questionnaire of foot care behaviors. Survey tools included general information questionnaire, foot care knowledge scale for diabetic patients and Nottingham Foot Care Assessment Scale in Chinese version. Independent-samples t test and oneway ANOVA were used in univariate analyses, whereas multiple stepwise linear regression was used in multivariate analyses. And Pearson correlation analysis was used to measure correlation between variables. Results: The scores of foot care behaviors were statistically significant in the group comparison of sex and glycosylated hemoglobin(t=-2.142, F=3.071, P<0.05). The patients′score of foot care behaviors was (45.31±7.74) scores. 50.9 percent (54/106) patients′scores were less than 45. And the score of foot care knowledge was (16.10±4.18) scores, which was in the medium level. The foot care behaviors level was lower in the patients whose foot care knowledge was poorer (t=-5.591, P<0.01). Foot care knowledge, glycosylated hemoglobin level and gender were the main influencing factors on foot care behaviors of type 2 diabetic patients (R²=0.221, F=9.664, P=0.000). Pearson analysis demonstrated that there was a positive correlation between knowledge score, glycosylated hemoglobin level and behavior score (r=0.377, 0.207, P<0.05). Conclusions The status of foot care knowledge and behaviors of type 2 diabetic patients are not optimistic in Jinshan District of Shanghai. It′s very important to strengthen the education and management on diabetic patients′foot care knowledge and behaviors, especially in male patients. Meanwhile, the patients whose glycosylated hemoglobin are well controlled should not be ignored.
