A Retrospective Study of the Relationship between Sleep Duration, Carbohydrate Intake and the Atherosclerotic Cardiovascular Disease Risk in Korean, Based on the 2013–2015 Korean National Health and Nutrition Examination Survey

ABSTRACT

BACKGROUND: Atherosclerotic cardiovascular disease (ASCVD) is known to be related to various factors. The aim of this study was to evaluate the association between the risk of ASCVD and sleep duration or carbohydrate intake using the Pooled Cohort Risk Assessment equations, which estimate a patient's 10-year primary risk.METHODS: A total of 7,781 adults were selected from the 6th Korean National Health and Nutrition Examination Survey, with no missing data as the inclusion criteria for analysis. The 10-year estimated risk of ASCVD risk was calculated using the Pooled Cohort Risk Assessment Equations. The χ² test was used to analyze the difference in the rates of ASCVD high-risk groups due to sleep duration and carbohydrate intake. Multiple logistic regression analysis was performed to verify the effects of sleep duration and carbohydrate intake on ASCVD risk.RESULTS: Shorter sleep duration (≤5 hours) was 1.166-times more likely in the ASCVD high-risk group than was optimal sleep duration (6–8 hours) (odds ratio [OR], 1.166; P < 0.05). Excessive sleep duration (≥9 hours) was also 1.504-times more likely in the ASCVD high-risk group than was optimal sleep duration (OR, 1.504; P < 0.001). Excessive carbohydrate intake (>65%) was 1.185-times more likely in the ASCVD high-risk group than was recommended carbohydrate intake (55%–65%) (OR, 1.185; P < 0.05).CONCLUSION: Inappropriate sleep duration and excessive carbohydrate intake increase the risk of ASCVD.
