Note. Each column represents one multivariable model. Shaded cells indicate statistically-significant interactions between the respective individual-level demographic characteristic and neighborhood-level poverty quintile in their association with the column health behavior factor. RR=relative risk; CI=confidence interval; ref=reference category.
