The Influence of Perceived Stress on Insulin Resistance in Adults with Type 2 Diabetes

Objective: To identify whether perceived stress is a risk-factor for higher cortisol levels and greater insulin resistance in Type 2 diabetic patients, using data from participants with and without diabetes in the National Survey of Midlife Development in the United States (MIDUS), specifically MIDUS II, Project 4. The following hypotheses were tested: (H1a) greater perceived stress would be associated with higher cortisol for Type 2 diabetic participants, (H1b) the perceived stress/cortisol relationship would be stronger for people with Type 2 diabetes than for those without it, (H2) greater perceived stress would be associated with higher Homeostatic Model Assessment-Insulin Resistance (HOMA-IR, insulin-resistance) for Type 2 diabetic participants, (H3a) subjective well-being would moderate the perceived stress/insulin resistance relationship for Type 2 diabetic participants, and (H3b) depression would moderate the perceived stress/insulin resistance relationship for Type 2 diabetic participants. Method: MIDUS, a longitudinal study of over 7,000 American adults, explores biopsychosocial factors that could contribute to variance in mental/physical health. Only complete data were utilized. Type 2 participants (n=115) consisted of 54 males and 62 females ranging in age from 36 to 81 years. Non-diabetic participants (n=1097) consisted of 470 males and 627 females ranging in age from 34 to 84 years. Results: None of the predicted relationships were statistically significant. Waist to hip ratio was significantly related to insulin resistance (r = .31, p = .001). Conclusions: Future studies should collect information about the type and duration of stressors in addition to perceptions about stress for those with Type 2 diabetes.
