Here, we explored the association between dietary potassium intake and all-cause and cardiovascular (CV) mortality in peritoneal dialysis (PD) patients. Methods: Here, we present a retrospective analysis of a prospective study. Patients that began incident PD in our center between 1 October 2002 and 31 August 2014 were screened. We recorded all demographic and clinical data at baseline. Repeated measurements were recorded at regular intervals to calculate time-averaged values. Spline regression analysis and Cox proportional regression models were used to evaluate the relationship between dietary potassium and mortality. Results: We followed 881 PD patients for 45.0 (21.5, 80.0) months; 467 patients died, of which 189 (40.5%) died of CV death and 93 were still on PD treatment. Compared with those who had baseline dietary potassium \u22651200 mg\/d, the majority of patients with lower dietary potassium were female, older, or poorly educated. They were prone to have poorer nutritional status, CV disease, and diabetes mellitus (p &lt; 0.05). In the unadjusted analysis, both baseline and time-averaged dietary potassium &lt;1200 mg\/d predicted higher all-cause and CV mortality (p &lt; 0.001~0.01). After adjusting for demographic and laboratory data, the association between potassium intake and all-cause and CV mortality weakened, which even disappeared after additional adjustment for dietary fiber, protein, and energy intake. Conclusions: Dietary potassium in PD patients was not independently associated with all-cause and CV mortality.<\/jats:p>","DOI":"10.3390\/nu15194271","type":"journal-article","created":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T07:49:29Z","timestamp":1696578569000},"page":"4271","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Dietary Potassium and Clinical Outcomes among Patients on Peritoneal Dialysis"],"prefix":"10.3390","volume":"15","author":[{"given":"Jinru","family":"Pan","sequence":"first","affiliation":[{"name":"Renal Division, Department of Medicine, Peking University First Hospital, Peking University Institute of Nephrology, Beijing 100871, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Health, Beijing 100034, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Education, Beijing 100034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Xu","sequence":"additional","affiliation":[{"name":"Renal Division, Department of Medicine, Peking University First Hospital, Peking University Institute of Nephrology, Beijing 100871, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Health, Beijing 100034, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Education, Beijing 100034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zi","family":"Wang","sequence":"additional","affiliation":[{"name":"Renal Division, Department of Medicine, Peking University First Hospital, Peking University Institute of Nephrology, Beijing 100871, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Health, Beijing 100034, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Education, Beijing 100034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiantian","family":"Ma","sequence":"additional","affiliation":[{"name":"Renal Division, Department of Medicine, Peking University First Hospital, Peking University Institute of Nephrology, Beijing 100871, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Health, Beijing 100034, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Education, Beijing 100034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Dong","sequence":"additional","affiliation":[{"name":"Renal Division, Department of Medicine, Peking University First Hospital, Peking University Institute of Nephrology, Beijing 100871, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Health, Beijing 100034, China"},{"name":"Key Laboratory of Renal Disease, Ministry of Education, Beijing 100034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"312","DOI":"10.1002\/ncp.10658","article-title":"Chronic Kidney Disease and Nutrition Support","volume":"36","author":"Chan","year":"2021","journal-title":"Nutr.
