Long sleep duration is associated with abdominal aortic calcification among male adults with chronic kidney disease: NHANES 2013–2014

Abstract

Abstract There are no studies exploring the correlation between sleep duration and abdominal aortic calcification (AAC). This study aims to investigate this relationship and its significance. Additionally, given the higher prevalence of sleep disorders and AAC in patients with chronic kidney disease (CKD), we conducted further studies in this population. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2013–2014. Sleep duration was assessed by a sleep questionnaire and categorized into 2–5, 6–8, and ≥ 9 h. The AAC-24 score is determined using the Kauppila scoring system and used for AAC assessment. Multivariable linear and logistic regression analysis were used to explore the relationship between sleep duration and AAC. Among the 2,996 participants, 14.29% reported nightly short sleep (2–5 h), 77.64% reported intermediate sleep (6–8 h), and 8.08% reported long sleep (≥ 9 h). After adjusting for potential confounding factors, among male participants with CKD, long sleep (≥ 9 h) significantly increased AAC-24 scores compared with intermediate sleep (6–8 h) (β: 2.12; 95% CI: 0.75, 3.50), and the risk of severe AAC (SAAC) was increased by 1.55 times (OR: 2.55; 95% CI: 1.02, 6.36). And among female CKD and non-CKD participants, sleep duration was not associated with AAC. Long sleep duration increases the risk of AAC among male adults with CKD. Prospective studies are needed to confirm this finding.
