Background: Globally, about 425 million people are suffering from diabetes mellitus (DM) which will be about 629 million by 2045. India is popularly known as World Diabetes Capital and is presently home of about 72.9 million diabetes patients. Poorly managed DM will increase the burden of both microvascular and macrovascular complications. One of the most common complications among them is diabetic foot ulcer (DFU) which affects about 7%24% of DM patients.
Aims and Objectives: This study was planned to determine the burden of DFU and its determinants among Type 2 diabetes mellitus (T2DM) patients attending integrated diabetes and gestational diabetes clinic.
Materials and Methods: An institution-based, observational, cross-sectional study was conducted from July to September 2018. A pre-designed, pre-tested, semi-structured schedule was used to collect clinicosocial data. Blood pressure of the study subjects was measured and classified as per Joint National Committee-8 guidelines. Peripheral vascular assessment of the feet was done by calculating ankle-brachial index (ABI) in both lower limbs using Diabetik Foot Care India Pvt. Limited vascular Doppler instrument having 8 MHz transducer. ABI ≤0.9 and absence of pulse in dorsalis pedis and/or posterior tibial arteries were considered as peripheral artery disease (PAD). Vibration perception threshold for peripheral sensory neuropathy was tested with the help of Diabetik Foot Care Pvt. Limited Digital Biothesiometer using 50 Hz frequency.
Results: Data were collected from 338 study participants. The frequency of DFU was found to be 9.5%. Increasing age, longer duration of diabetes, poor educational status, overweight/obesity, poor glycemic control, treatment with insulin, PAD, diabetic peripheral neuropathy, hypertension, ischemic heart disease, and hypothyroidism were significantly associated with DFU.
Conclusion: There is high frequency of DFU among T2DM patients. Most of the risk factors are modifiable and if taken care of the occurrence of DFU can be prevented and/or delayed.
