  • NOTE: Analyses were conducted using CHIS data with survey replicate weights and survey data procedures for proportion estimation. P values are from Wald tests of hypotheses of equality of two proportions.

  • * Sample sizes for Asian subgroups do not sum to the Asian total because the Asian category includes smaller Asian subgroups not listed separately.
