Current Knowledge/Study Rationale: One concern with peritoneal dialysis (PD) is that patients may have a higher risk of sleep apnea (SA) due to intra-abdominal pressure increase and worsened ultrafiltration capacity. Despite this concern, it is uncertain if the risk of SA differs between patients on PD, hemodialysis (HD), and those without uremia.
Study Impact: The patients on PD, but not HD, had a higher risk of SA than patients without uremia. Besides, male patients on PD had a significantly higher risk of SA risk than male patients on HD. In contrast, the risk of SA did not differ between female patients on PD and HD.
