  1. a Coded 1 = female, 0 = male
  2. b Coded 1 = Black, 0 = White, Hispanic or other
  3. c Coded 1 = married/cohabitating, 0 = other
  4. d An interaction between age and race resulted in varying ORs. For age, OR = 1.05 per year of age for white, Hispanic and others and OR = 1.01 per year of age for Blacks. For race, OR = 6.05 at age 30, OR = 4.20 at age 40, and OR = 3.02 at age 49.
