Stanford-Moore G, et al. - Researchers investigated the interaction between known risk factors for squamous cell carcinoma of the head and neck (SCCHN) and socioeconomic status (SES), using the North Carolina Head and Neck Cancer Epidemiology Study (a population-based case–control study). Participants were patients with SCCHN identified from North Carolina between 2002 and 2006 (n=1,153), as well as age, sex, and race-matched controls (n=1,267) selected from driver license records. Household income, educational attainment, and health insurance constituted SES measures. They used logistic regression to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Both current smoking and drinking were more strongly associated with SCCHN among those households making < $20,000/year compared to household incomes > $50,000/year.
