Abstract: In 1994, the National Institutes of Health convened a Technology
Assessment Conference "to provide physicians with a responsible assessment
of bioelectrical impedance analysis (BIA) technology for body composition
measurement." In 1997, Serono Symposia USA, Inc., organized an invited
panel of scientists and clinicians, with extensive research and clinical
experience with BIA, to provide an update. Panel members presented reviews
based on their own work and published studies for the intervening years.
Updates were provided on the single and multifrequency BIA methods and
models; continued clinical research experiences; efforts toward establishing
population reference norms; and the feasibility of establishing guidelines
for potential use of BIA in a clinical setting. This report provides a
summary of the panel's findings including a consensus on several technical
and clinical issues related to the research use of BIA, and those areas that
are still in need of additional study.
