Investigating lifestyle determinants of muscle and physical function, and the impact on patient experience and support needs in kidney disease (DIMENSION-KD)
What is the purpose of the study?
Patients with kidney disease suffer from poor physical functioning, low levels of physical activity, and increased levels of disability. This makes doing everyday activities difficult and reduces their quality of life. Many public health recommendations emphasise the importance of a ‘healthy lifestyle’, however further research is needed to identify the important lifestyle factors impacted by kidney disease, as well as understanding the needs of the patient.
DIMENSION-KD aims to establish the effect and association of kidney disease with different patient characteristics and investigates the impact this has on their quality of life and physical functioning. The study also aims to explore the patient ‘living’ experience of these factors.
What does it involve and what do we hope to find out?
We hope to understand why people with kidney conditions suffer from a variety of health problems and symptoms, and what impact this has on their quality of life.
The study consists of different parts:
Part A will involve patients completing a questionnaire pack assessing symptoms, physical function, physical activity, dietary intake, and quality of life.
Part B will involve an optional additional visit to the renal research area in the hospital for further measures such as fat and muscle mass, muscle quality, physical function and strength, potential markers in the blood, and physical activity levels.
Part C is a qualitative part exploring the patient ‘living experience’ of kidney disease and the impact and role of lifestyle on patient quality of life, physical functioning, and health status.
Update August 2020: We have just added a new part to the DIME-KD study to explore the impact of the Covid pandemic on lifestyle and access to healthcare of people living with kidney disease.
Part CV involves an online survey for kidney patients, their significant others and the healthcare staff involved in their care. There is also an optional qualitative telephone interview to explore the issues in more depth.
Update September 2022: Another part has been added to the DIME-KD study:
Part E involves an online survey for patients with kidney disease and their significant others to explore their lived experience and impact of sleep problems and access to green and blue space.

What’s next?
The study is recruiting patients currently. If you are interested in finding out more information about this study please contact us. The results will be fundamental in identifying the needs of kidney patients for the future development of a multi-inclusive lifestyle intervention.
