Obesity and diabetes are chronic metabolic diseases in which psychological aspects play many important roles. Affective temperament plays a key role in the regulation of human behavior. The aim of this study was to determine the relationship between affective temperament and the parameters describing carbohydrate metabolism.
The study was conducted in a population of 185 people (139♀/46♂) with obesity. In 42 patients impaired fasting glycemia (IFG) and/or impaired glucose tolerance (IGT) were diagnosed, while 56 patients were diagnosed with type 2 diabetes. The level of fasting glycemia, glycated hemoglobin and peptide-C were selected to assess carbohydrate metabolism. The Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) was used to perform an analysis of the dimensions of the affective temperament.
There were no significant correlations between the affective temperament and the parameters of the carbohydrate metabolism in the non-diabetic population. In diabetes group, there were significant positive correlations between anxiety temperament and fasting blood glucose (r = 0.34, p = 0.01), C peptide level (r = 0.29, p = 0.03) and HbA1C (r = 0.40, p = 0.002). Negative correlations of depressive temperament with the level of peptide C (r = -0.26, p = 0.05) and HbA1C (r = -0.22, p = 0.08) and positive with the level of fasting blood glucose (r 0.45; p = 0.0003) were also observed.
The obtained results indicate the existence of significant relationships between the dimensions of affective temperament and the alignment of carbohydrate metabolism.
