Values are mm Hg (95% confidence interval).

DBP = diastolic blood pressure; Mex Am = Mexican American; NH = non-Hispanic; SBP = systolic blood pressure; other abbreviations as in Table 1.

  • p value for linear trend, assessed with regression models, with 2-year survey cycle treated as a continuous variable, and adjusted for sex, ethnicity, and/or age group when appropriate. Age-adjusted: use the 20 to 39, 40 to 59, and 60+ years age groups to adjust to the 2000 Census population by the direct method.
