Stepping up foot care: assessment over foot care knowledge and behavior among individuals with diabetes of risk levels

Background Diabetic foot is a global threat to public health, as it can lead to infections and amputations and cause significant pain and economic costs for patients. Diabetic foot patients in northern China have more severe local ulcers, worse prognosis, and longer disease duration.Objective This study assessed the foot risk levels and foot care knowledge and behavior status of people with diabetes with different foot risk levels, and investigated the factors that influence the occurrence of high-risk foot in diabetes.Methods This cross-sectional survey included 410 hospitalized people with diabetes. Demographic and disease-related data and foot risk stratification status were collected using investigator-designed questionnaires. Foot care knowledge and behavior questionnaires were also used.Results Among the 410 participants, a total of 367 cases were classified as high-risk feet, among which 135 cases were rated as grade 1, 202 cases grade 2, and 30 cases grade 3. Foot care knowledge surveys revealed low scores in the areas of shoe and sock selection, foot and footwear examination, and management of foot problems. Foot care behavior surveys showed low scores in the areas of foot and footwear examination, management of foot problems, and foot injury risk behavior. One-way ANOVA revealed significant differences in foot care behaviors among patients with different foot risk classifications (p < 0.05), while no significant differences were observed in foot care knowledge scores. Multivariate logistic regression analysis showed that age, history of cerebrovascular disease, and foot care behavior scores were factors influencing the occurrence of high-risk foot in people with diabetes.Conclusion The results of this study showed a high prevalence of high-risk foot in diabetics; The knowledge and behavior of foot care in diabetics with different foot risk levels were both at a moderately low level; There were differences in foot behavior scores among patients with different foot risk classes, but, counter-intuitively, no significant differences in foot care knowledge. The study found that advanced age, history of cerebrovascular disease, and low foot care behavior scores are risk factors for high-risk foot in diabetes. Therefore, it is necessary to screen patients with diabetes for high-risk feet and implement targeted interventions according to the results.
