This Notice of Funding Opportunity (NOFO) aims to support research on interdisciplinary population approaches to increasing awareness of the relationship between alcohol and cancer risk, understanding and changing social norms related to alcohol consumption, developing and/or evaluating alcohol policy approaches, and the development, testing, and implementation of population-level interventions to reduce alcohol-related cancer risk. Applications that address multiple levels of consumption, such as moderate and heavy drinking, are of particular interest, as well as those focusing on alcohol use disorder (AUD) from the perspective of cancer prevention and control. Proposals addressing understudied areas are encouraged, as is attention to underrepresented minority (URM) populations experiencing cancer and alcohol-related disparities such as American Indian, Alaskan Native, and sexual and gender minority populations.
