Abbreviation: aOR, adjusted odds ratio; NA, not applicable.
Any advertising exposure excludes don’t know/not sure responses; boldface aORs indicate significance (P < .05).
P value, based on Pearson χ2 test, was used to determine whether the proportion exposed to advertising is equal across subgroups for a given characteristic.
aORs are adjusted for all characteristics listed in the table as indicated, from a model with a main exposure variable of average proximity to nearest retail marijuana store.
Non-Hispanic multiple races included respondents who selected more than 1 race and declined to respond to a question asking them to select a race that best represents them.
Community setting was assigned by using student home zip code; 13.7% of 8th graders and 5.5% of 11th graders were not assigned because of missing zip code information.
aORs in this table are from a logistic regression model with average proximity to nearest retail marijuana store as a primary exposure variable. Similarly aORs from a separate model using number of retail stores as the exposure variable with no stores as reference group were 1.05 (95% CI, 0.86–1.29) for 1 to 3 stores and 1.74 (95% CI, 1.36–2.22) for 4 or more stores among 8th graders, and 1.28 (95% CI, 0.98–1.67) for 1 to 3 stores and 1.59 (CI, 1.24–2.03) for 4 or more stores among 11th graders.
