a

Adjusted for race/ethnicity, home ownership, employment status, age and age2. Household income is adjusted for number of household members.

b

Adjusted for factors in Model 1. Income model is adjusted for education and education model is adjusted for income.

c

Adjusted for factors in Model 1 and mutually adjusted for all other SES measures (income, education and property values).

d

PR is prevalence ratio

e

P for trend calculated by including a grouped linear variable in the model. For example, education was coded as follows: <HS=1, some college=2, ≥college=3.

Pairwise comparisons of each prevalence ratio to the reference group were also made. The p-values for these comparisons correspond to the following symbols,
