Addressing Health Disparities
Immigrant Health Disparities in Breast Cancer Research
While immigrant scientists are making groundbreaking discoveries in breast cancer research, they are also at the forefront of addressing a critical issue: immigrant health disparities in cancer research. These disparities extend beyond breast cancer to affect various aspects of cancer prevention, detection, and treatment within immigrant communities.
Studies have highlighted significant gaps in cancer screening rates, access to care, and participation in clinical trials among immigrant populations. For instance:
- Screening Disparities: Foreign-born women are less likely than U.S.-born women to have ever had a mammogram (88.3% vs 94.1%). This disparity is even more pronounced for foreign-born women living in the U.S. for less than 25% of their lifetime, with only 76.4% having ever had a mammogram.
- Clinical Trial Participation: Immigrant populations are often underrepresented in cancer clinical trials, limiting the applicability of research findings to these communities.
- Meeting Screening Recommendations: Foreign-born women were less likely to meet the U.S. Preventive Services Task Force (USPSTF) recommendations for mammography screening (68.8% vs 73.0% for U.S.-born women).
- Regional Differences: After adjusting for sociodemographic factors, women from Mexico, Central America, and the Caribbean were more likely to meet screening recommendations, while women from Central and South Asia remained less likely to do so compared to U.S.-born women.
- Acculturation Effect: Length of time in the U.S. appears to be an essential factor, with more extended residence associated with screening rates more similar to U.S.-born women.
Immigrant scientists are uniquely positioned to address these disparities, bringing their cultural insights and personal experiences to bear on this critical issue.
Innovative Approaches to Address Screening Disparities
Researchers are developing targeted strategies to overcome immigrant health disparities in cancer research and care:
- Culturally Tailored Outreach: Dr. Reshma Jagsi’s work on disparities in breast cancer treatment and outcomes has informed the development of culturally appropriate screening programs for immigrant communities.
- Language-Specific Initiatives: Organizations founded by immigrants, such as the Asian American Breast Cancer Network and the Latina Breast Cancer Initiative are creating language-specific educational materials and support services to improve screening rates.
- Community-Based Participatory Research: Dr. Zainab Shonibare focuses on developing community-based approaches to increase cancer awareness and screening participation among immigrant populations. This method ensures that research is relevant and beneficial to the communities it aims to serve.
- Multilingual Health Communication: Immigrant scientists with language skills are critical in tailoring health communication strategies to ensure vital cancer information reaches diverse communities. A 2022 study showed that people who don’t speak English well are less likely to get screened for cancer if they can’t communicate easily with their doctor.
