Evaluation of the quality of life of older people with diabetes.

Introduction and objective: Diabetes is commonly classified as a chronic disease of affluence due to the frequency of its incidence and the rate of its spreading. The aim of the study was to evaluate the quality of life of geriatric patients with type 2 diabetes.

Material and methods: 294 seniors diagnosed with type 2 diabetes living in the Lower Silesian Province in south-western Poland took part in the study. The study used a self-developed questionnaire collecting clinical and socio-demographic data, the WHOQOL-Bref questionnaire, Acceptance of Illness Scale (AIS), Self-Care of Diabetes Inventory (SCODI) and the Geriatric Depression Scale (GDS).

Results: Significant relationships of QoL with BMI, level of education and place of residence, were observed. BMI was significantly negatively correlated with the psychological domain of functioning and the environmental functioning, the level of education was correlated with physical health, psychological and environmental functioning, while the place of residence was correlated with the perception of the QoL and environmental functioning. Acceptance of illness was positively correlated with the perception of QoL and one's physical health. The results of regression analyses in predicting QoL in all domains showed that all models were a good fit for the data (p < 0.001), and the single predictor was maintenance of self-care. The level of depression was negatively correlated to a statistically significant degree with the perception of QoL and one's health condition.

Conclusions: BMI, level of education and place of residence had the highest impact on the quality of life of the participants. The quality of life of the participants improved with the increase in the acceptance of their illness. The higher the level of depression exhibited by the participants, the poorer they evaluated their quality of life.
