  • a Models adjusted for age, race (white, black, other race), and design variables (dichotomized age (<65 vs. ≥65 years), poverty census enumeration district (residence vs. nonresidence), and family income (<$3,000, $3,000–$6,999, $7,000–$9,999, $10,000–$14,999, and ≥$15,000)).

  • b Models adjusted for above variables, and United States region (Northeast, Midwest, South, West), residence (rural, urban, suburban), education (<high school, high school completion, >high school), recreational sun exposure (little, occasional, frequent), recreational physical activity (little/none, moderate, much), smoking status (never, former, current), current alcohol intake (none, little, moderate, heavy), and energy intake (tertiles).

  • c P for trend was obtained for each pattern by including in the model a variable representing the median value for each tertile.
