Current or Former Smokers Low Income Smokers at Risk for Greater Burden of Tobacco-Related Health Outcomes Theresa Juster MPH, Francis Boscoe PhD, Harlan Juster PhD Background Disparities in current smoking by income and other measures of socioeconomic status (SES) have been well established among adults in the US. Adults living below the federal poverty level (low SES) experience significantly higher rates of current smoking compared to adults living at or above the poverty level (high SES). Rates of smoking prevalence over time have decreased faster among higher SES adults compared to low SES adults. Results Table 1.

Methods NYS lung cancer incidence cases were obtained from the NYS Cancer Registry November 2015 for diagnosis years 2000, 2009, 2012 and 2013. Cases were geocoded to census tracts based on address at time of diagnosis. Data were merged with poverty level files obtained from the U.S. Census Bureau by year and census tract. Cancer cases were assigned a poverty category of ‘Low’ for cases with census tracts that had less than 5% households below poverty level, or ‘High’ for cases with census tracts with greater than or equal to 20% households below the poverty level. Age-adjusted rates were then calculated using the direct method. Separately, prevalence of current smoking by individual income (<$25,000 vs >=$25,000) was measured from the 1985-2014 NYS BRFSS data files. Prevalence of heart attack, stroke, diabetes, chronic obstructive pulmonary disease (COPD), coronary heart disease (CHD), arthritis, kidney disease, skin cancer, other cancers, and asthma by tobacco use and income (<$25,000 vs >= $25,000) were analyzed from the 2012 NYS BRFSS. Logistic regression and chi-square analysis was conducted using SAS 9.4. The interaction of smoking status and income on health outcomes was also tested.

Findings A greater proportion of low income smokers are single, unemployed, have less than a high school education, have poor mental health, are disabled, and have public insurance compared to smokers with high income (Table 1). The rate of current smoking among low income adults is significantly higher compared to high income adults (Fig. 2). Low income populations experience greater lung cancer incidence compared to high income populations with a disproportionally slower change in rate over time (Fig 1). Significantly higher prevalence of tobacco-related chronic diseases exist among smokers with low incomes compared to those with high incomes (Table 2, Fig. 3 & 4). A significant interaction between income and smoking exists when evaluating the prevalence of heart attack, stroke, COPD and asthma; disease rates are highest among low income smokers compared with high income smokers and never-smokers (Table 3, Fig. 3 & 4). Conclusions Low income smokers carry a greater burden of tobacco-related chronic diseases compared with never smokers and high income smokers. Differential access to health care, lifestyle and rate of tobacco consumption could account for the greater burden of disease among low income smokers compared with high income smokers. Attention to reducing smoking within this vulnerable population is vital.
