Pharmaceutical advertisements in medical journals received in a medical clinic: are we having "too much of a good thing"?

Abstract

A convenience sample of all medical journals found in a medical clinic was reviewed for pharmaceutical advertisements. Ads were present in 25 (96%) of the 26 journals. Ad space varied from 0-34% (mean 12) in research, and 9-48% (mean: 36) in nonresearch journals. In 23 (88%) journals, individual ads consisted of more than one page. Colorful glossy insert-ads, of up to nine pages, were seen in 18 (69%) journals. Six (23%) journals contained more advertising than editorial pages. Many ads were longer than the longest article in that journal. Medical journals devote considerable space to pharmaceutical ads. Excessive pharmaceutical advertising may bias the journals' owners and readers and may be distracting and annoying.
