title: Relationship between dietary caffeine intake and blood pressure in adults.
abstract: The aim of this study was to determine the consumption frequency of caffeinated foods and beverages and daily caffeine consumption amounts, and examine relation between caffeine and blood pressure (BP). A cross sectional door-to-door interview was conducted with 1329 volunteers between the ages of 20 and 60 (mean ages 29.9 ± 10.8 years) and based in Ankara/Turkey. The rate of individuals whose BPs were above 140/90 mmHg was 13.5%. The median caffeine consumption was 150.0 ± 122.06 mg. Although no significant correlation was found between total caffeine intake and diastolic blood pressure (DBP) of individuals, a positive correlation was observed between daily total caffeine and systolic blood pressure (SBP) (p < .05). Also, when analyzed factors that could be associated with DBP and SBP, BMI had effect in the model formed for both types of BP (p < .05). While smoking status associated with SBP (p = .002), gender and waist circumference related to DBP (p < .05) As a result relationship between caffeine intake and BP was affected other factors.
