Estimates are ORs (95% CI).
Model 1 adjusts for age, age-squared, survey cycle and sex. Models 2–3 add caregiver education, caregiver marital status, and PIR. Model 3 adds the tract deprivation index. Model 4 adds the PIR by deprivation index interaction. Percentage of change in the race/ethnicity coefficients (β) are calculated on the logit scale using model 1 coefficients as the reference.
−2LL, −2 log likelihood; BIC, Bayesian Information Criterion; ICC, intraclass correlation coefficient; PCV, percent change in variance; PIR, poverty-to-income ratio.
