This research aimed to explore diabetic foot prevalence and to study factors predicting diabetic foot among type 2 diabetes mellitus patients. For exploring diabetic foot prevalence, data were collected by chart reviews from 1,084 samples receiving health care services from public health centers, Bangkok Metropolitan. For studying factors predicting diabetic foot, data were collected by self-reported questionnaires from 140 samples. Data were analyzed using descriptive statistics and logistic regression analysis. The results revealed that diabetic foot prevalence was 302 cases per 1000 people. Significant factors that predicted diabetic foot were duration of having diabetes (OR = 1.767, 95% CI: 1.364 - 2.290), health behavior (OR = .868, 95% CI: 798 - .945), health literacy (OR = .931, 95% CI: .892 - .971), and hemoglobinA1c (OR = 2.062, 95% CI: 1.074 - 3.958). All factors could predict diabetic foot by 67% (R2 = .667)
Nurse practitioners and other health care providers who took care of type 2 diabetes mellitus patients could bring information from this study to design interventions for caring patients. The interventions should focus on helping patients be able to control their hemoglobinA1c, promoting healthy behavior, enhancing appropriate health literacy, especially for those who had long duration of diabetes in order to prevent or delay diabetic foot.
