The National Academy of Sciences library staff, with the input of committee staff, performed searches of the following on-line bibliographic databases for the years 1991 to 1996 inclusive, using the correct terminologies for the databases in question and supplying delimiters: Medline, Psychinfo, Sport Database, National Technical Information Service (NTIS), and Defense Research On-line System (DROLS)/Defense Technical Information Center (DTIC) Work Unit and Technical Report databases. Relevant material published prior to 1991 was obtained by drawing upon the 1995 Institute of Medicine (IOM) report mentioned above, the Committee on Military Nutrition Research report on Body Composition and Physical Performance (IOM, 1994), the IOM report on Nutrition during Pregnancy and Lactation (1990), as well as the expertise of the BCNH committee.
These searches were supplemented with a number of additional small searches of Medline, the General Accounting Office (GAO) database, the Bureau of Labor Statistics on-line site, Federal Research in Progress, and the National Institutes of Health Computer Retrieval of Information on Scientific Projects (CRISP) System.
Author and title citations were obtained initially and screened by staff. Because of considerable overlap among three of the topic categories, many citations appeared in more than one search. The initial screening considered only the apparent relevance of the topic to the report. Obvious animal studies were eliminated, as were studies of pediatric and geriatric nutrition, and studies on breast cancer. Abstracts were obtained for titles that were deemed worthy of consideration and were sent to BCNH committee members in the appropriate working groups. Committee members designated abstracts for which they wanted full articles. This judgment was based largely if not solely on topic.
Although the BCNH committee initially considered the application of a set of criteria to inclusion of materials for review, it was determined that because of the limited number of military studies of relevance to the topics, all relevant military materials would be included for consideration and their limitations discussed, if necessary. Civilian literature was included as background and supporting material; wherever possible, critical reviews of the civilian literature were drawn upon to provide this background.
