Quality of Life and Associated Factors among Elderly Diabetic Patients in Shiraz, 2014

Background: Today, the quality of life (QoL) studies have an important role in public health care, especially among the old adults suffering from chronic diseases such as diabetes. Diabetes and its complications can widely affect various aspects of QoL. Therefore, the present study aimed to assess diabetic patients’ QoL and identify the factors that affect it. Methods: A cross-sectional study was conducted on 593 randomly selected diabetic patients aged 60 years and above who were admitted in 13 diabetes clinics in Shiraz, Iran, in 2014. Diabetes Quality of Life-Brief Clinical Inventory (DQOL-BCI) questionnaire was used to assess the quality of life in these patients. Univariate and multivariate linear regression analyses were performed, using Stata software, version 12, to identify the predictors of DQoL. Results: The participants’ mean DQoL score was 41.8±6.2 with a mean age of 66.2±6.0 years. Multivariate linear regression analyses revealed that FBS level (115-180 mg/dL: P=0.05; above 180 mg/dL: P=0.02) and duration of diabetes (4-9 years: P=0.06; above 9 years: P=0.002) were two important clinical predictors of DQoL. Conclusion: This study demonstrated a relationship between clinical and socio-demographic factors and diabetic patients’ QoL. Considering these related variables could lead to effective control of diabetes complications and improvement of the patients’ QoL.
