Disparities in diabetic foot examinations: a cross-sectional analysis of the behavioural risk factor surveillance system.

Aim: This study aimed to identify how frequent poor mental health days, a depressive disorder diagnosis, frequent poor physical health days, or physical inactivity affect annual foot examinations in individuals with diabetes.

Background: Diabetes mellitus (DM), particularly type 2, is a growing problem in the United States and causes serious health complications such as cardiovascular disease, end-stage renal disease, peripheral neuropathy, foot ulcers, and amputations. There are guidelines in place for the prevention of foot ulcers in individuals with diabetes that are not often followed. Poor mental health and poor physical health often arise from DM and contribute to the development of other complications.

Methods: We performed a cross-sectional analysis of the 2021 Behavioural Risk Factor Surveillance System dataset to determine the relationship between annual foot examinations and frequent poor mental health days, a depressive disorder diagnosis, frequent poor physical health days, or physical inactivity using a bivariate logistic regression model. The regression model was controlled for age, sex, race/ethnicity, health insurance, level of education, current smoking status, and Body Mass Index (BMI) category.

Findings: Our results showed that 72.06% of individuals with frequent poor mental health days received a foot check, compared with 76.38% of those without poor mental health days - a statistically significant association (AOR: 1.25; 95% CI: 1.09-1.43). Of those reporting a sedentary lifestyle, 73.15% received a foot check, compared with 77.07% of those who were physically active, which was also statistically significant (AOR: 1.31; 95% CI: 1.14-1.49). Although individuals reporting depressive disorder diagnoses and frequent poor physical health days had lower rates of foot examinations, these results were not statistically significant. To reduce rates of foot ulcers and possible amputations, we recommend the implementation of counselling or support groups, increased mental health screening, educational materials, or exercise classes.
