Results in bold are statistically significant.

Model A = Unadjusted Prevalence Ratio (PR)

Model B = Adjusted Prevalence Ratio (aPR)

^*Variables included in the models: age, income, education, foreign born, marital status, race/ethnicity, parity, and objective stress.

^**Variables included in the models identical to * above with addition of CES-D (<23 vs ≥23).
