The role of psychological coronary risk factors in insulin and glucose metabolism.
The association between psychological coronary risk factors and serum insulin, and C-peptide and blood glucose concentrations, [the latter measured while fasting and during the oral glucose tolerance test (OGTT)], was examined in healthy middle-aged men (n = 64). The results indicate that among the evaluated psychological risk factors, high levels of hostile paranoia and vital exhaustion were most consistently associated with an enhanced insulin/glucose ratio, and enhanced insulin, C-peptide and glucose responses during OGTT. The associations persisted after controlling for age, smoking, alcohol consumption and visceral fat distribution. Thus, in addition to age, life-style factors and obesity, psychological factors may have an effect on insulin and glucose metabolism.
