The means listed above are all adjusted for the following covariates: gender, age, global health status, fruit and vegetable intake, minutes per week of physical activity, smoking (never, former, and current smoker), body mass index, education, and practice site. Unadjusted means (not shown) are similar to the adjusted means.

Percents may not add to 100% because of rounding.

Total N is lower for ovarian cancer, because women who had had both ovaries removed were not asked about perceived risk for ovarian cancer, worry, or control.
