Kwon YJ, et al. - In this cross-sectional study performed in 1,984 Korean adults (range of age 19-81 years), researchers examined the link between circadian rhythm and serum lipid levels. They calculated propensity scores using logistic regression with age, sex, and body mass index. They performed propensity score matching analysis to assess 435 subjects. With each group comprising 145 subjects, three groups were defined (morningness, intermediate, and eveningness groups). Using the Morningness-Eveningness Questionnaire, they assessed circadian preference. Findings revealed a significant link between circadian preference and blood lipid levels. A greater risk of atherosclerotic cardiovascular diseases could be seen among subjects with evening preference, who also had significantly increased levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol vs those with morning or intermediate preference.
