Abstract
To the Editor: Wolfe et al1 recently reported that 53% of US adults use the Internet to seek health-related information. Measurement of Internet use, however, has generally been obtained by self-report, rather than by assessment of actual search behaviors.1,2 Because search engines represent the principal method by which people seek Internet-based information,3 we analyzed the frequency of use of search engine keywords for health-related subject matter.
