In a May 14, 2014, Nature commentary (see Nature. 2014 May 15;509(7500):282-3.), NIH leadership stated an intention to develop and implement policies requiring applicants to consider sex as a biological variable in the design and analysis of NIH-funded research involving animals and cells. Although we have made major progress in achieving balance of sex in human studies — women now account for roughly half of the participants in NIH-funded clinical trials — we have not seen a similar pattern in biomedical research. Animal studies have typically focused on males, and investigators studying cell models have often not reported the sex of the individual from which the cells were obtained. Even if both sexes are included in a study design, resulting data may not be analyzed or disaggregated by sex. The failure to consider sex as a variable may leave critical knowledge gaps and undermine the quality and reproducibility of research findings (see Nature. 2014 Jan 30;505 (7485):612-3). Consideration of sex is a critical component of rigorous experimental design, just like randomization, blinding, sample-size calculations, or other basic design elements. By developing a policy to ensure that sex is considered in NIH-funded studies, NIH will ensure that sex and sex differences are examined in all aspects of biomedical research. This will lead to a stronger foundation upon which to build clinical research and clinical trials.
The NIH has formed a trans-NIH working group to inform the development of these policies. This Request for Information (RFI) seeks input from the research community and other interested stakeholders on the following topics regarding the consideration of sex as a biological variable in biomedical research. Public comment is sought for but not limited to the following:
