Note. All percentages are survey adjusted column percentages. Reference class in multinomial regression analyses specified as Class 1 (i.e., “High Protection, Low Risk”). Relative risk ratios (RR) adjusted for age, gender family income, and father in household. RR in bold represent a significant difference at p < .05 and 95% confidence intervals (95% CI) that do not overlap with 1.00.
