Background Little is known about the relationship between dietary patterns and hypertension among Chinese population. Method A nationally representative sample of 23 671 participants aged 18–59 years were recruited by the 2002 China National Nutrition and Health Survey. We conducted factor analysis using information from a validated food frequency questionnaire to derive dietary patterns. Results Three major dietary patterns, defined as ¡®Westernˈ, ¡®traditional northernˈ, and ¡®traditional southernˈ, were identified. T he score of the Western pattern is positively associated with blood pressure, whereas the score of the traditional southern pattern is negatively associated with blood pressure. In multivariate analyses the traditional northern pattern score was associated with an odds ratio (OR) of 1.30 (95% CI 1.11–1.53, P trend = 0.0001) comparing with the lowest quartile. The OR for the top quartile of score for the traditional southern pattern was 0.73 (95% CI, 0.59–0.89, P trend = 0.0040) compared with the lowest quartile of traditional southern pattern score. Conclusion We observed a strong positive relationship between the traditional northern pattern and hypertension. In addition, the traditional southern pattern was negatively associated with hypertension.
