Abbreviations: CI, confidence interval; NA, not applicable; OR, odds ratio.
a
Crude ORs calculated by using a logistic regression model for grade, sex, and race/ethnicity.
b
Significant at P = .05.
c
Numbers do not total expected value because of a small portion of responses of “no answer” to the question, “what is your biological sex?”
d
All categories are non-Hispanic, except Hispanic. Percentages for racial or ethnic categories of American Indian, Asian, black, Hispanic, multiple races, Pacific Islander, and white do not total 100 because of a small portion of responses of “no answer.”
e
Somali and Hmong race/ethnicity asked about as a yes-or-no question separately from the question on race; reference group for each is “no response.”
