Abstract：Objective To understand the relationship between dyslipidemia and dietary factors in Jiangsu adults. Methods A multi-stage stratified cluster random sampling method was used to select 9,180 permanent adult residents aged 18 years in 12 monitoring sites in Jiangsu province in 2014, and questionnaire surveys were conducted to collect the general information and dietary status of the research subjects. Fasting venous blood was taken to detect the level of blood lipids. Factor analysis was employed to establish dietary patterns, and then multivariate logistic regression was applied to analysis of the relationship between dietary patterns and dyslipidemia. Results The total prevalence rate of dyslipidemia in Jiangsu residents aged 18 years and above was 32.2%. As for dietary patterns, this study showed that there were four main types of dietary patterns among the residents in Jiangsu province, namely, animal pattern, pasta pattern, pickled vegetable and egg pattern and milk dairy pattern. The total cholesterol content was the highest in the fourth-class group of pasta pattern. Triglyceride was the highest in the fourth-class group of animal pattern as well as the fourth-class group of milk pattern, but the lowest in the first-class group of milk pattern. No statistically significant difference was observed in high-density lipoprotein among different patterns and equivalents. There was a statistically significant difference in the prevalence rate of dyslipidemia among the quartiles of pasta and milk patterns in males (P<0.05). No statistically significant difference was found in the prevalence rate of dyslipidemia among the four dietary patterns of females (P>0.05). After adjusting age, urban and rural areas, economic income, educational background and body mass index, the quantiles Q2 and Q3 of pasta pattern in males showed an increased risk of dyslipidemia (Q2:OR=1.645, 95%CI: 1.172-2.308; Q3:OR=1.606, 95%CI: 1.151-2.240). The quantile Q2 of pickled vegetable and egg pattern in females might reduce the risk of dyslipidemia (OR=0.728, 95%CI: 0.543-0.977), but the quantile Q4 of milk pattern might increase the risk of dyslipidemia (OR=1.514, 95%CI: 1.081-2.121). Conclusions The prevalence rate of dyslipidemia was higher in adults in Jiangsu province. Milk pattern was positively correlated with abnormal blood lipid of the residents, pasta pattern was positively correlated with abnormal blood lipid of male residents, and pickled vegetable and egg pattern was negatively correlated with abnormal blood lipid of female residents.
