  • Multiple Poisson regression models were fitted to assess determinants of self-reported SHS exposure in the different environments. Multivariate models included all variables listed in table. Ref, referent. *Statistically significant results at P < .05.

  • a Self-reported exposure to secondhand smoke in ≥1 of the 5 environments assessed: at home, in a vehicle, at school, at work, and in any indoor/outdoor public area.

  • b Includes American Indian or Alaska Native; and Native Hawaiian or other Pacific Islander.

  • c Current any tobacco users were students who reported using any of the following tobacco products in the past 30 days: cigarettes/flavored cigarettes, roll-your-own tobacco, cigars/flavored cigars, pipes, bidis, kreteks, hookahs, electronic cigarettes (e-cigarettes), smokeless tobacco (dissolvable tobacco, chewing tobacco/snuff/dip, or snus), or “some other new tobacco products not listed.”

  • d Current cigarette smokers were students who reported using cigarettes within the past 30 days (not mutually exclusive of other tobacco products).
