Abstract

The National Institutes of Health (NIH) issued guidelines in 1990 requiring the inclusion of women and minorities in all NIH-sponsored clinical research and revised these guidelines in 1994 to require analysis of clinical trial outcomes by sex of the subjects. To ascertain whether these guidelines are yet reflected in the scientific literature, we performed a survey of research articles published in major medical journals. All original research articles in the New England Journal of Medicine, the Journal of the American Medical Association, the Journal of the National Cancer Institute, and Circulation from the years 1993, 1995, 1997, and 1998 were examined. Articles were assessed for use of human subjects, source of funding, type of study (clinical trial or not), sex-relatedness of the disease or condition, inclusion of women as study subjects, and analysis of outcomes by sex of the subjects. Among NIH-funded, non-sex-specific studies, approximately one fifth of the studies published each year failed to include women as research subjects. This number did not improve significantly over the 5-year period analyzed. Only one quarter to one third of the studies that included women analyzed data by sex of the subjects, with no significant change over the time period studied. Although most clinical trials included women as study subjects, in only a small percentage of the trials were results analyzed by sex of the subjects, with no significant improvement over time. These data clearly show the need for increased awareness and monitoring of recruitment and retention of women in clinical research and for analysis of data by sex of the subjects to be carried out consistently.
