💡 Tips for applicants
- Frame your research question around specific work-related factors driving health inequities. Connect to existing literature on occupational disparities.
- Demonstrate how your team has expertise in both occupational health and health disparities research. Include letters of support showing collaboration strength.
- Use preliminary data to show feasibility. Even pilot results strengthen your innovation narrative and methods.
- Address equity explicitly in recruitment and retention plans. Show how you'll engage underrepresented populations in occupational research.
- Build in sufficient time for peer review. Allow 3-4 months before submission for institutional sign-offs and grants office review.
⚠️ Common mistakes
Weak preliminary data or feasibility section. Study sections need evidence you can execute the proposed work.
Unclear mechanisms explaining how work exposures or conditions cause health disparities. Connect your variables logically.
Overlooking equity in study design. Failed to adequately address recruitment, retention, and relevance to disparity populations.
