Geoethnic-sensitive and cross-culture differences ofdietary patterns and blood pressure among fiveethnic populations in China

摘要

Objective:The present study was aimed to examine the relation of dietary patterns and oxidative DNA damage to blood pressure (BP) among five Chinese national ethnic populations Methods: A random sample of 1901 middle-aged Chinese men and women was collected from five ethnic groups in 11 cooperative study centers in China Results: (1) Significant differences in mean BP, prevalence of hypertension and various dietary markers were observed among the five populations (2) N,Na/K ratio and body mass index (BMI) were positively correlated with BP, and magnesium (Mg), 3-methyhistidine (3MH) and taurine were inversely correlated with BP (3) Factor analyses using eight variables (BMI, N,K, Na/K ratio, calcium, Mg, 3MH and taurine) yielded three factors that explained 68% of total variance of BP among the five ethnic samples Conclusion: Geoethnic sensitive and cross-cultural differences should partly explain the diet-BP association.
