BackgroundInsomnia, a known cardiovascular risk factor, is common in end-stage renal disease (ESRD) patients. There is growing acknowledgment of a potential bidirectional relationship between cardiovascular diseases and sleep disorders. We previously assessed the risk factors for common sleep disorders in ESRD patients. This follow-up study assesses the demographic and clinical cardiovascular-related risk factors for insomnia diagnosis in ESRD patients, given their increased cardiovascular burden.MethodsThis study is a retrospective analysis of the United States Renal Data System to evaluate risk factors for insomnia diagnosis. All patients in the USRDS who started dialysis between 2005 and 2019 were eligible for inclusion. Demographic risk factors analyzed were age, race, sex, ethnicity, dialysis modality, and access type. Cardiovascular risk factors, including obstructive sleep apnea (OSA) and central sleep apnea (CSA), were also evaluated.ResultsFemale sex, OSA, CSA, myocardial infarction, congestive heart failure, peripheral vascular disease, cerebrovascular disease, diabetes, chronic obstructive pulmonary disease, obesity, and hypertension were associated with an increased risk of insomnia. Increasing age, non-white race, Hispanic ethnicity, and catheter or other/peritoneal dialysis access type were associated with a decreased risk of an insomnia diagnosis.ConclusionVarious cardiovascular diseases were independent risk factors for an insomnia diagnosis in this retrospective cohort. Further study is indicated to investigate potential mechanisms underlying this connection.Copyright © 2024 Southern Society for Clinical Investigation. All rights reserved.
