Note: AOR: adjusted odds ratio; CI: confidence interval. Because of a small number, results for Native Hawaiians/Pacific Islanders are considered preliminary.

1

Each adjusted logistic regression included all variables listed in the first column.

2

The two groups (family income <$75,000) were combined due to a small cell size.

3

The two groups (small metro, nonmetro) were combined due to a small cell size.

4

The variable was not included in the model due to a small cell size. Due to the sample size, results for Native Hawaiians/Pacific Islanders are considered preliminary.
