The fоllоwing study аppeаred recently in the Americаn Jоurnal of Epidemiology (January 2013). Please characterize its basic study design: Coffee, Tea, and Fatal Oral/Pharyngeal Cancer The authors examined associations of caffeinated coffee, decaffeinated coffee, and tea intake with fatal oral/pharyngeal cancer in the Cancer Prevention Study II, begun in 1982. Among 968,432 men and women who were cancer free at enrollment, 868 deaths due to oral/pharyngeal cancer occurred during 26 years of follow-up. Cox proportional hazards regression was used to estimate multivariable-adjusted relative risk. Intake of >4 cups/day of caffeinated coffee was associated with a 49% lower risk of oral/pharyngeal cancer death relative to no/occasional coffee intake (relative risk = 0.51, 95% confidence interval: 0.40, 0.64). The association was not modified by sex, smoking status, or alcohol use. No association was found for tea drinking. In this large study, caffeinated coffee intake was inversely associated with oral/pharyngeal cancer mortality. Research is needed to elucidate biologic mechanisms whereby coffee might help to protect against these often fatal cancers.
