Psychological Insulin Resistance in Patients with Type 2 Diabetes.

AIMS/HYPOTHESIS: To identify risk factors associated with psychological insulin resistance (PIR) in Indian type 2 diabetes (T2DM) population.

METHODS

Patients with T2DM, aged 18 years, undergoing treatment with oral hypoglycaemic agents and providing written informed consent were considered eligible for the study. Patient's data was collected by face-to-face interaction using 5 validated diabetes questionnaires--Diabetes Attitude Scale, Diabetes Knowledge Test, Diabetes Self-Efficacy Scale, Interpersonal Processes of Care Survey-29, and Barriers to Insulin Treatment scale. Demographic variables, categories of patients based on their annual family income, education, glycosylated haemoglobin (HbA1c), occupation and type of healthcare setup were correlated with overall scores of validated questionnaires. Statistical analyses were performed using Pearson correlation coefficients, analysis of variance, two-group t-test and hierarchical multiple regression.

RESULTS

One hundred ninty-eight patients with T2DM were enrolled where 63% were males, 52% had HbA1c <7% (<53 mmol/mol), 32% were in service, 35% had the annual family income between Rs 100,000-500,000, 50% were graduates and 81% were enrolled from private healthcare set ups. Significant high opposition to use insulin was observed in females, patients based at home, patients with insufficient education, and patients visiting government set-ups compared to males, service-class patients, graduates, and patients approaching private set-ups, respectively.

CONCLUSIONS

In India, major factors contributing to PIR were fear of injection or fear of pain during injection, fear of hypoglycemia, social stigma and lack of education. Effective interpersonal interactions with healthcare providers could help to counteract PIR, especially in patients who are not sufficiently literate highlighting the need of skilled healthcare staffs in Indian public hospitals.
