  1. Abbreviations: BP blood pressure, CI confidence interval, DRA dietary risk assessment
  2. Note: Boldface indicates statistical significance *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001
  3. a Data are means except where noted
  4. b 3 categorized as other race
  5. c Participants selected intervention group at 6 month follow-up visit; if they did not attend this visit they were assigned to lifestyle group
  6. d Carotenoid index, calculated as the sum of α-carotene, β-carotene,β-cryptoxanthin, and zeaxanthin. Data presented are for nonsmokers and available only through 12 month follow-up visit. A higher index indicates greater fruit and vegetable consumption. Statistical tests performed on log-transformed data
  7. e Includes walking for transportation and exercise
