ABSTRACT
Objective To investigate the effects of different dietary patterns on brachial ankle pulse wave velocity in northern industrial cities. Methods According to the selection criteria,from 2014 to 2015, 22436 health checkup persons were selected as the subjects of Kailuan Group,they were followed up with health examination and questionnaire investigation, at the same time, the brachial ankle pulse wave velocity was detected. According to the dietary advice given by the Chinese dietary guidelines,the proportion of animal and plant food in the food frequency questionnaire and the supply of nutrients are divided into 4 groups,which are the traditional Chinese diet group (3 585 cases),the Western diet group (13 639 cases),the balanced diet group (1 309 cases),the Mediterranean diet group (3 903 cases). Logistic multivariate regression analysis was used to analyze he risk factors of atherosclerosis. Results The mean value of brachial ankle pulse wave velocity in 22 436 cases was ( 1 462. 46 ± 320. 69) cm/s, and the incidence of peripheral arteriosclerosis was 50. 78%(11 392/22 436). The incidence of arteriosclerosis around the balanced diet group, the Mediterranean diet group,the traditional Chinese diet group and the Western diet group were 48. 82%( 639/1 309), 49. 12%(1 917/3 903),50. 49%(1 810/3 585),51. 51%(7 026/13 639),and the difference between the groups was statistically significant (P＝0. 024); after adjusting other related risk factors,compared with the balanced diet group,the risk of peripheral arteriosclerosis in the Mediterranean diet group,the traditional diet group and the Western diet group was 121(95%CI:0. 557～2. 258),1. 015(95%CI:0. 663～1. 554),1. 033(95%CI:0. 677～1. 575), respectively. Conclusion The incidence of peripheral arteriosclerosis increased gradually in the balanced diet group,the Mediterranean diet group,the Chinese traditional diet group and the Western diet group, but there was no statistical significance in the risk of peripheral arteriosclerosis after adjusting other related risk factors. This Conclusion requires more large samples,long-term follow-up study to further confirm.
