ObjectiveTo explore the value of quality intima-media thickness（QIMT）in evaluating the relationship between food intake and carotid atherosclerosis.MethodsA total of 866 volunteers in our hospital from February to December2018 were enrolled in and divided into two groups

including carotid atherosclerosis group 354 cases and non-atherosclerosis group 512 cases.QIMT technique was used to evaluate the carotid intima-media thickness（IMT）

and the results of two groups was compared.Partial correlation was used to analyze the correlation between food components and carotid sclerosis

conditional Logistic regression analysis was used to compare the differences in carotid sclerosis risk between different food intakes.ResultsThe IMT in the carotid atherosclerosis group was 829 μm（724

981）

and the non-atherosclerosis group was591 μm（531

664）.The thickness of intima between two groups were signicantly different（P<0.05）.The intake of vegetables

fruits

and dairy products was negatively correlated with carotid sclerosis（r=-0.100

-0.198

-0.248

all P<0.05）

while the intake of poultry and livestock was positively correlated with carotid sclerosis（r=0.278

P<0.05）.After adjusting for confounding factors

insufficient intake of vegetables and fruits and excessive intake of poultry and livestock will increase the risk of carotid sclerosis（OR=1.93

2.03

3.72

all P<0.05）.ConclusionQIMT technique can more accurately assess the carotid artery-media membrane thickness

thus guide food intake to avoid the risk of carotid arteriosclerosis.
