About the study

Consuming alcohol is a dose-dependent and modifiable risk factor for breast cancer. Although alcohol consumption contributes to an estimated 16% of breast cancer cases, awareness of the link between alcohol and breast cancer risk remains low. Systematically developed and tested health warnings can support population-based approaches and intervention strategies to decrease alcohol consumption and breast cancer risk. For instance, the U.S. Food and Drug Administration can mandate specific warnings through statements (e.g., "WARNING: This product contains nicotine…") and color graphics depicting the negative health consequences of products that can harm public health, such as tobacco and alcohol. However, health warning statements and graphics should be assessed among intended audiences before implementation. Research has outlined principles for effective health warning statements. This project will test different health warning statements about the health effects of alcohol.
