The Effect of Physical Activity Level Evaluated by Wrist-wearable Devices on Cardiovascular Disease Risk and Other Outcomes in Peritoneal Dialysis Patients

This study aims to explore how daily physical activity (PA) levels affect the heart health and cognitive function of patients on peritoneal dialysis (PD). Using a fitness tracker, the investigators will measure how much patients move during the day and see if lower activity levels are linked to a higher risk of heart disease or memory issues. The study has two parts: Part A: The investigators will evaluate 266 patients to understand their current PA levels and how these relate to heart health and cognitive function. Part B: The investigators will follow the same patients over a year, measuring their activity at the beginning and after 12 months. The investigators will divide them into two groups-those who increase their PA and those whose PA decreases-and follow their heart health and memory function over two years. The goal is to understand whether higher PA levels can reduce the risk of heart problems and memory issues in PD patients.
