Agenda
o Why I use TUS-CPS for inequality analyses
o Illustrate the use of the TUS-CPS to examine tobacco control inequality research questions with 4 examples from my own work
• Nativity (immigrant) and racial/ethnic differences in smoking patterns, and related to tobacco-control related policy

Why use the TUS-CPS for nativity inequality analyses?
o TUS-CPS has better information on immigration related variables and tobacco use than any other survey
o TUS-CPS is a large representative survey
o TUS-CPS also has good information on demographic and socioeconomic control variables

Significance: What do we know about smoking bans & smoking ban coverage? o Smoking bans prevent ETS exposure, and reduce
smoking among smokers
o Tobacco use regulations do not protect everyone equally.
o Uneven coverage due to voluntary passage, tobacco control patchwork at multiple levels

Significance: Why examine inequalities among immigrants?
o Demographic imperative o Immigrant status (nativity) is often conflated with
race/ethnicity o Immigrants disproportionately in low-wage and
low-skilled jobs o Immigrants less likely to enjoy workplace benefits

Conclusions & Implications
o Industry and occupation are important mediators for why immigrants (or other groups) have lower coverage by a smokefree policy
o Policies often exempt jobs with higher concentrations of minorities
o A voluntary policy regime will be less effective for covering certain minority groups because occupational segregation will induce systematic disparities.

Conclusion
o Immigrants exhibited weaker associations between workplace smokefree policy & smoking
o Why?• Differential industries accounted for 16% of the
weaker policy effects among immigrants• Workplace smoking policies may be more effective for
those with higher smoking prevalence/consumption • Other causes may be more important for smoking
among immigrants

Significance: Support for Smoking Bans
o The population’s opinions about where smokingshould be allowed are a general indicator ofsupport for tobacco control policy
o Public opinion• one catalyst for enacting tobacco control policy• e.g. state ballot initiatives/referenda
o Knowledge of support by demographic group mayaid advocates to identify voter constituencies forcoalition building in election strategies

Variables: Support for Smoking Bans
o Outcome: summary measure of support for total smoking bans in 6 venues • Individual questions asked whether smoking should be allowed
in “all areas, some areas, or not allowed at all” in (1) restaurants, (4) bars and cocktail lounges, (2) hospitals, (5) indoor sports venues, (3) indoor work areas, (6) indoor shopping malls.
• Support for smoking ban based on answering that smoking should “not be allowed at all” for each venue
• Summary measure of support created by summing # of venues out of 6 where a person supports a ban, & dichotomizing.
o Strong support = support for banning smoking in 4 of 6 venues (based on Gilpin et al. 2004).

Significance: Why look at state-specific patterns of smoking?
o Descriptive analysis• Surveillance
o Prioritizing resources for programs and policy
• Implicates state level causal explanations
• Influential states may drive national prevalence
• Etiologic hypothesis generation Theresa L. Osypuk 31

Analysis: Multilevel Modeling
o 2-level multiple logistic regression predictingcurrent smoking• Predicted smoking prevalence from state-level
residuals, from multilevel multiple logistic regressionmodels controlling for covariates
• Markov Chain Monte Carlo estimation o To adjust for complex survey design
o Mapped state predicted probability of smokingfor each race/gender group• Relative adjusted (regression-based) estimates
significantly higher or lower than the nationalprevalence

Conclusions
o A race-specific pattern of smoking among the 50 states
o State tobacco variables (taxation and agriculture) did not account for remaining state smoking variance.
o Descriptive regression-based mapping may be valuable for place-patterned tobacco use surveillance
