Background With the change of lifestyle, atherosclerotic cardiovascular disease (ASCVD) is showing a younger trend as an important component of ASCVD. Snoring as a common health problem related to sleep breathing, which is a characteristic indicator of obstructive sleep apnea-hypopnea syndrome (OSAHS) . However, there are few studies on the correlation between snoring and ASCVD, and it is still necessary to identify this factor to provide scientific basis for early intervention. Objective To investigate the correlation between snoring frequency and 10-year risk of ASCVD in middle-aged and elderly population. Methods From 2018 to 2021, a multi-stage stratified cluster sampling method was adopted to investigate the permanent residents aged 35-75 in Jing'an District. General information of the subjects was collected through questionnaire survey, and laboratory tests were used to collect total cholesterol (TC) , triacylglycerol (TG) , low-density lipoprotein cholesterol (LDL-C) , and high-density lipoprotein cholesterol (HDL-C) . Snoring frequency: snoring 1-2 times per week was considered as mild snoring, snoring 3-4 times per week was considered as moderate snoring, and snoring 5-7 times per week was considered as severe snoring; the 10-year risk of ASCVD 0.05) . Further analysis of the relationship between snoring and ASCVD risk factors showed that severe snoring was a risk factor for hypertriglyceridemia, hypercholesterolemia, hyper-low-density lipoproteinemia and hypo-high-density lipoproteinemia, and moderate snoring was a risk factor for hyper-low-density lipoproteinemia and hypo-high-density lipoproteinemia compared with no snoring (P
