Diabetes and Quality of Life: Key Components and Determinants
Quality of life (QoL) in people with diabetes is a complex, multi-dimensional concept that includes physical, mental, psychological, and social aspects. Diabetes-related quality of life (DRQoL) specifically focuses on how diabetes impacts general health, satisfaction with diabetes management, the direct impact of diabetes on daily life, and the ability to self-manage the condition Trikkalinou2017Wicaksana2025Speight2019. These components are measured using both generic and diabetes-specific tools, such as the Audit of Diabetes-Dependent Quality of Life (ADDQoL) and the Diabetes Treatment Satisfaction Questionnaire (DTSQ) Wicaksana2025Bradley2002Oluchi2021.
Impact of Diabetes on Quality of Life
People with diabetes generally report a lower quality of life compared to those without chronic illnesses, though their QoL may be better than those with other serious chronic diseases . The presence of diabetes complications—such as coronary artery disease, renal failure, retinopathy, neuropathy, and sexual dysfunction—significantly worsens QoL Trikkalinou2017Rubin1999Rodríguez-Almagro2018. Comorbidities like obesity, hypertension, dyslipidemia, depression, and arthritis further deteriorate QoL in diabetic patients Trikkalinou2017Panahi2024Rodríguez-Almagro2018.
Physical and Mental Health in Diabetes
Both physical and mental health are affected by diabetes. Studies show that individuals with diabetes have lower physical and mental component scores on quality of life assessments compared to non-diabetics Panahi2024Rodríguez-Almagro2018. Poorly controlled diabetes is particularly associated with reduced physical health, while even controlled diabetes can negatively impact mental health. Depression and being female are notable contributors to diminished QoL in both physical and mental domains Panahi2024Rodríguez-Almagro2018.
Social and Lifestyle Factors
Social and lifestyle factors, such as dietary restrictions, work limitations, and social isolation, also play a significant role in reducing QoL for people with diabetes Verma2017Mohanty2022Bradley2002. The greatest negative impact is often seen in the loss of dietary freedom, which can affect participation in family and cultural events Mohanty2022Bradley2002. Younger age, female gender, lower education, and poor glycemic control are all independent predictors of worse QoL .
Measurement Tools for Diabetes-Related Quality of Life
A wide range of instruments are used to measure QoL in diabetes, including both general and disease-specific tools. The ADDQoL, PAID, and DHP are among the most commonly used, each assessing different aspects of the diabetes experience Wicaksana2025Bradley2002Oluchi2021. However, there is still no consensus on the best tool to use, and routine assessment of diabetes-specific QoL is not yet standard practice in clinical care Speight2019Oluchi2021.
Interventions and Future Directions
While some interventions aimed at improving health status and self-management have shown little to moderate benefit in improving QoL, more research is needed to determine the most effective strategies Trikkalinou2017Rubin1999. Improving glycemic control and preventing complications are key to enhancing QoL, but addressing psychosocial factors and individual needs is equally important Rubin1999Speight2019Rodríguez-Almagro2018.
Conclusion
Diabetes has a significant negative impact on quality of life, affecting physical, mental, and social well-being. The presence of complications and comorbidities, as well as social and lifestyle factors, further worsen QoL. Comprehensive assessment and individualized interventions are essential to improve the lives of people living with diabetes. Ongoing research and better integration of QoL measures into clinical practice are needed to guide effective care and support.
