Background. National pipe-smoking prevalence data have rarely been rep
orted, and mortality associated with pipe smoking has not been estimat
ed. Methods. We analyzed National Health Interview Survey data from 19
65, 1966, 1970, 1987, and 1991 to estimate adult pipe-smoking prevalen
ce in the United States. For each of these years, we estimated pipe sm
oking-attributable mortality from chronic obstructive pulmonary diseas
e and cancers of the oral cavity, larynx, esophagus, and lung. Results
. From 1965 to 1991, the prevalence of current pipe smoking for men de
clined 12.1 percentage points (from 14.1% to 2.0%) while pipe smoking
remained very uncommon among women. By 1991, pipe smoking was a behavi
or found primarily among men age 45 years or older, Most men who smoke
d pipes also used other tobacco products, especially cigarettes, About
830 deaths (range 720-2,495) in 1965 and 1,095 deaths (range 655-2,82
0) in 1991 were attributable to pipe smoking. Conclusions. If current
trends continue, pipe smoking will become extremely rare in the United
States by the year 2000, Reasons for the decline in pipe smoking may
include the lack of appeal of pipe smoking to women and adolescents or
the increasingly unfavorable image of smoking behavior in general. Pr
evention and cessation efforts need to be directed against all forms o
f tobacco, including smokeless tobacco use, cigar smoking, and pipe sm
oking.
