Abstract

Aims: Sleep duration and quality are increasingly recognized as potential contributors to cardiovascular disease risk, with serum lipids playing a crucial role in this relationship. However, the results regarding this association have been inconsistent across different ethnic groups. This study aims to investigate this association in an Iranian elderly population. Methods: Totally 1392 people 60 to 69 years old were included in this study. Sleep duration and quality were assessed by the Pittsburgh sleep quality index (PSQI). Logistic and linear regression models were employed to determine the association of sleep duration and quality with serum lipid levels; moreover, the effects of other potential confounders were also controlled. Findings: Most of the participants had low sleep quality (70.47 %), which was more notable in males (80.08 %), compared to females (59.15 %), and most of the participants slept 6–7 h per day (42.2 %). No association was observed between sleep quality and serum lipid levels including HDL (OR = 1.12; P = 0.871), LDL (OR = 0.80; P = 0.451), total cholesterol (OR = 0.89; P = 0.702) and triglyceride (OR = 1.13; P: 0.477). As well as, no association between sleep duration and LDL; (β = 0.35; P = 0.094), total cholesterol (β = 0.02; P = 0.918), triglycerides (β = −0.02; P = 0.846), and HDL (β = −0.06; P = 0.534). Conclusion: In the elderly population, poor sleep quality is typical, particularly among males. Sleep quality and duration were not associated with serum lipid profiles, including TG, TC, LDL, and HDL. © 2023
