Beyond diagnosis: Investigating factors influencing health-related quality of life in older people with type 2 diabetes in Slovenia

Aims

To examine the present state of health-related quality of life (HRQOL) among elderly individuals with type 2 diabetes (T2D) receiving integrated care and identify risk factors associated with low HRQOL.

Methods

A multi-centre cross-sectional survey among elderly individuals with T2D, treated in Slovenian urban and rural primary care settings was performed. HRQOL was investigated using EuroQol 5-dimension (EQ-5D) questionnaire and Appraisal of Diabetes Scale (ADS). Furthermore, socio-demographic, clinical, and laboratory data were collected. Low HRQOL was defined as EQ-5D utility score <10%. Statistical analysis was performed using univariate and multivariate binary logistic regression statistics.

Results

Examining 358 people with median age of 72 (range 65–98) years and with a mean EQ-5D utility score of 0.80, the study found that lower HRQOL correlated with older age, higher body mass index (BMI), lower education, elevated depressive symptoms, increased challenges across all EQ-5D dimensions, and less favourable appraisal of diabetes. When considering age, gender, education, and HbA1c, the main predictors of low HRQOL were BMI (OR 1.35, 95% CI 1.04–1.76, p = 0.025) and ADS score (OR 1.63, 95% CI 1.13–2.35, p = 0.009).

Conclusions

To improve HRQOL, integrated care models should consider interventions that target mental health, obesity prevention, chronic pain management, diabetes education, self-management, and treatment plan personalisation.
