Sex differences in application, success, and funding rates for NIH extramural programs

Area of Science:

• Biomedical research workforce
• Grant funding analysis
• Research diversity initiatives

Background:

• Understanding sex differences in research funding is crucial for promoting workforce diversity.
• National Institutes of Health (NIH) award programs are a key area for examining these disparities.

Purpose of the Study:

• To analyze sex-based differences in NIH award programs.
• To identify potential strategies for enhancing diversity in the research workforce.

Main Methods:

• Data from NIH extramural grants were retrieved from the electronic Research Administration Information for Management, Planning, and Coordination II database in 2010.
• Statistical analysis was employed to assess sex differences in securing NIH funding and subsequent research success.

Main Results:

• No significant sex differences in success or funding rates were observed in most NIH award programs.
• Lower female participation in some programs was attributed to fewer women applicants, not lower success rates.
• Men demonstrated higher application and funding rates for subsequent grants compared to women.

Conclusions:

• While women and men show comparable success at initial career stages, men with prior NIH grant experience have higher subsequent application and funding rates.
• Women tend to receive larger R01 awards, but men secure more R01 awards throughout their careers.
• Despite progress, continued efforts are necessary to eliminate remaining sex-based disparities in NIH funding and career progression.
