OBJECTIVES: This study aimed to explore the relationship between the dietary patterns and blood pressure (BP) in Taiwanese females. METHODS: Cross-sectional study by surveying 269 Taiwanese females, 40 years of age or older, was conducted, using structured questionnaires, and BP and physiological parameters measurements. Descriptive statistics were performed for all measures as appropriate. To assess differences among the vegan, semi-vegetarian, and meat-eater groups by demographic, BP and health behavior data, Chi-Square test and Fisher’s exact test for categorical variables, or analysis of variance tests and independent t-test for continuous variables were performed. The relationship between BP and dietary patterns was assessed using a multiple linear regression (MLR) model. All data were analyzed using SPSS 20.0 statistical analysis software. RESULTS: Among the total participants, 65 (24.2%), 105 (39.0%), and 99 (36.8%) were the vegan, semi-vegetarian, and meat-eater groups. Significant difference was found among three groups according to age, race, educational, employment, stress and waist-hip ratio. Based on BP, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly different among the three groups. When SBP and DBP were considered independently, waist-hip ratio was significantly different between the good and poor controls in both SBP and DBP. Therefore, BP was predicted as a function of the three groups considering for waist-hip ratio. The R for the MLR model was 0.02, indicating that 2% of the variance in SBP and DBP were accounted for by the independent variables. The three groups were observed to be a significant predictor of SBP (β=0.14, p=.02) and DBP (β=0.15, p=.02). CONCLUSIONS: The dietary pattern is a predictor for the SBP and DBP outcome in Taiwanese females.
