β represents unstandardized regression coefficients.

Model 1: Adjusted for age, sex, race and height.

Model 2: Adjusted for age, sex, race, height, body mass index, smoking status, prevalence of diabetes, total cholesterol and physical activity measured at Y30 examination.

Abbreviations: SBP: systolic blood pressure and DBP: diastolic blood pressure; SD: standard deviation.
