Objective To explore the association between dietary patterns and dyslipidemia in adult residents of Hefei City, and to provide scientific basis for the prevention and control of dyslipidemia in this region. Methods A multi-stage stratified cluster random sampling method was used to conduct a questionnaire survey and physical examination among 10 024 permanent residents aged ≥18 years in five districts and counties of Hefei City. The dietary intakes were analyzed using a semi-quantitative food frequency table. Four dietary patterns were established, including multivariate dietary pattern, processed food pattern, salted vegetable and egg pattern, and cereal and vegetable pattern. Then the four dietary patterns were grouped into four quartiles according to the factor scores (G1-G4) and parameterized by the G1. Finally, the relationship between different dietary patterns and the prevalence of dyslipidemia in the four categories was explored by logistic regression analysis. Results The total prevalence of dyslipidemia among the survey respondents was 32.24%, with hypercholesterolemia, hypertriglyceridemia, hypo-HDL cholesterolemia and hyper-LDL cholesterolemia accounting for 5.04%, 10.56%, 13.20% and 3.44%, respectively. After adjusting for several confounders, logistic regression analysis showed that multivariate dietary pattern was negatively associated with the risk of hyper-LDL cholesterolemia (G4: OR=0.658, 95% CI: 0.469-0.924). Processed food pattern was a risk factor for dyslipidemia, and positively associated with the risk of hypercholesterolemia, hypo-HDL cholesterolemia, and hyper-LDL cholesterolemia ( G4: OR=1.326, 95% CI: 1.031-1.705; OR=1.253, 95% CI: 1.056-1.486 and OR=1.401, 95% CI: 1.05-1.868 respectively). Grain and vegetable pattern was negatively associated with the risk of hypercholesterolemia and hypertriglyceridemia (G2: OR=0.716, 95% CI: 0.549-0.933; OR=0.796, 95% CI: 0.657-0.964). Conclusion There is an association between dietary patterns and dyslipidemia. Residents should reduce the intake of fried and other processed foods, increase the intake of grains, cereals and vegetables and adhere to a balanced and diversified dietary pattern in their daily diet.
