Dietary patterns and cardiovascular diseases among Chinese high-risk population aged 35 years and older: A 6-year cohort study

This study aims to investigate the dietary patterns of Chinese individuals aged 35 years and older who are at high risk of cardiovascular disease (CVD) and to explore the correlation between these dietary patterns and the risk of CVD. A total of 28,747 high-risk participants in China PEACE in Zhejiang Province from 2014 to 2019 were included in the analysis Dietary data were obtained using the Food Frequency Questionnaire, and dietary patterns were extracted through factor analysis. Cox regression was used to examine the relationship between the dietary patterns and CVD risk in the high-risk groups. Four dietary patterns were identified. The "Bean, egg, milk and pickle" dietary pattern was associated with an increased risk of CVD (HR = 1.29; 95% confidence interval (CI):1.09, 1.54; p＜0.05), after adjusting for confounders. In contrast, the "Seafood and animal meat", "Wheat and coarse cereals", and "Rice and vegetable" dietary patterns did not show a significant impact on CVD risk. These findings provide valuable insights for dietary guidance in high-risk groups and have significant implications for the prevention and management of CVD.
