Prevalence of behavioral risk factors (current smoking, low physical activity, low fruit and vegetable intake, high caloric fat intake, obesity, high alcohol intake, and low multivitamin use) according to colorectal cancer screening status in a sample of 11,090 adults ages 50 yrs and older drawn from the 2000 NHIS

Colorectal cancer screening status

Low multivitamin use*64.4 (63.0-65.8)52.0 (50.2-53.7)
  • NOTE: All percentages are weighted. Due to missing data, sample sizes vary as follows: not adherent to screening, n = 6,323 to 6,819; adherent to screening, n = 3,998 to 4,254.

    Abbreviation: 95% CI, 95% confidence interval.
