Did You Know? Study Shows that Increasing Smoke-Free Homes among Low-Income Populations Can Reduce Income Disparities in Smoking Cessation

Lower rates of successful quitting among low-income populations in the United States may be from slower dissemination of smoke-free homes, a predictor of cessation. A recently published study explored the role of smoke-free homes in cessation behavior across income levels. Researchers analyzed data from the 2002-2003 (n = 2801) and 2010-2011 (n = 2723) Tobacco Use Supplements to the Current Population Survey.

 

Findings included:

  • Between the two surveys, heavy smoking (≥ 1 pack/day) declined by 17%, and smoking prevalence declined by 15% among those with higher-incomes.
  • Although similar in 2002, the prevalence of smoke-free homes was 33% lower among individuals living <300% FPL than those living ≥300% FPL.
  • Whereas smoking ≥ 1 pack/ day was associated with lower odds of 30+ days abstinence, having a higher income and a smoke-free home were associated with greater odds of 30+ day abstinence.

 

The researchers concluded that increasing the diffusion of smoke-free homes among low-income populations may attenuate at least a third of the income disparities in smoking cessation, highlighting the need for interventions to increase adoption of smoke-free homes among low-income households.
