Abbreviation: CI confidence interval.
a Odds ratios were computed using a binary logistic regression model adjusted for all covariates listed in the table. Statistically significant odds ratios are noted in bold.
b A respondent was considered to be a combustible tobacco user if they reported using cigarettes, cigars/cigarillos/little cigars, pipes, roll-your-own-cigarettes, bidis, clove cigarettes, hookahs or water pipes on at least 1 day during the past 30 days. Non-combustible tobacco users were defined as respondents who reported using chewing tobacco/snuff/dip, snus, or dissolvable tobacco products on at least 1 day during the past 30 days.
c A respondent was considered to live with a tobacco user if they reported that anyone who lives with them now smokes cigarettes, uses smokeless tobacco such as chewing tobacco, smokes cigars, cigarillos, or little cigars, or uses any other form of tobacco.
