aCovariates in addition to those listed: education status, marital status, foreign-born status, needs walking assistance, U.S. Census region, obesity or overweight, smoking status, binge drinking, tanning bed use, ever had a skin exam, ever had cancer, family history of melanoma, personal history of melanoma, sunless tanning product use, and health insurance status.
bReported walking categories for at least 10 min in the past 7 days.
cSignificant linear contrast of regression coefficients: F(1, 12,306) = 9.24, p = .003.
dIndividuals were categorized into four activity levels based on the 2008 Physical Activity Guidelines for Americans: highly active (>300 min/week of light or moderate-intensity aerobic activity, 150 min of vigorous-intensity aerobic activity, or an equivalent combination per week [i.e., moderate-intensity equivalent activity]), sufficiently active (150–300 min/week of moderate-intensity equivalent activity), insufficiently active (some activity but less than 150 min/week of moderate-intensity equivalent activity), and inactive (no light to moderate or vigorous-intensity aerobic activity for at least 10 min).
eSun avoidance was defined as always or usually staying in the shade or responding not going into the sun for any sun protective question.
fSun protective clothing was defined as always or usually wearing at least one: wide-brimmed hat, long sleeved shirt, or long clothing to the ankles.
gRegular sunscreen use was defined as always or usually using sunscreen with SPF15+ (sun protection factor).
