Analyses were conducted on a subset of non-Hispanic white subjects reporting a history of previous NMSC for which there was a complete set of data, using pooled data from the 2005 and 2010 National Health Interview Survey (NHIS).
At least one sunburn reported in the last year
Percentages are weighted according to U.S. census data and reported with standard error (SE) measurements; weighted percentages (Wt %) may not add up to 100% as variables with missing responses are not reported.
Prevalence odds ratio (POR) estimates were adjusted for age (18–39, 40–49, 50–59, 60–69, 70–79, 80+ years), sex, region (Northeast, Midwest, South, West), family history of skin cancer, sun sensitivity (severe sunburn, moderate sunburn, mild sunburn, no sunburn), highest level of education (less than high school, high school diploma, some college, college degree or higher), BMI (<25.0, 25.0–<30.0, 30.0+ kg/m2), physical activity level 0, <180, 180–<360, 360+ min/wk), previous full-body skin check, and survey year (2005, 2010).
Analysis among all subjects reporting previous NMSC with complete data; model not adjusted for sun sensitivity because this covariate was used to create the variable of sun avoidance.
Self-reported frequency of sun-protective practice on a warm sunny day; analysis among sun-exposed individuals reporting previous NMSC with complete data
Subjects who frequently used at least two of the four examined sun protection practices on a warm sunny day; analysis among sun-exposed individuals reporting previous NMSC with complete data
P-value for linear trend was computed using the Wald statistic, treating the categorized exposure variable as a continuous variable.
