ABSTRACT: Newspaper Reporting of Screening Mammography
[12/18/2001; Annals of Internal Medicine]
Background: Continuing controversy surrounds screening mammography,
particularly for women 40 to 49 years of age. Newspapers are
potentially important sources of information on this topic, but
it is not known whether they provide well-founded and objective
information and recommendations.
Objective: To examine how screening mammography is reported
in newspapers.
Design: Cross-sectional descriptive study.
Setting: 6 top-circulation U.S. newspapers, 1990 to 1997.
Measurements: Number of articles about screening mammography,
issues covered by the articles, information sources, content
and sources of quotes, recommendations cited in articles,
and presentation of risks and benefits.
Results: The most common theme of newspaper articles about
mammography was screening for women 40 to 49 years of age.
Thirty-one percent of the articles presented information
without citing a source or justification. Quotes and
recommendations in the articles were approximately twice
as likely to support as to express reservations about mammography
for women aged 40 to 49 years.
Recommendations changed little
over time and rarely reflected changes in recommendations of
national organizations. Of the 102 articles describing the benefits
of mammography, 95% expressed them in relative terms and 11%
expressed them in absolute terms.
Conclusions: Newspapers tended to overrepresent support for
screening mammography for women aged 40 to 49 years.
Reports
would have been improved by identification of all sources for
information cited, less reliance on relatively few sources,
and discussion of benefits in absolute as well as relative
terms.
Medical journalism may benefit from identification
of standards similar to those used for reporting medical research.
