This study estimates bicycle helmet use among adults in the United Sta
tes, examines factors associated with helmet use among adult bicyclist
s in 1994, and examines other safety-related practices. A telephone su
rvey of 5238 randomly dialed households in the United States was condu
cted. The participants were randomly selected adult (aged greater than
or equal to 18 years) respondents, and the main outcome measure was b
icycle riding and helmet use in the last 30 days. We estimate that 20.
2% of adults reported riding a bicycle in the 30 days preceding their
interview. Of the bicyclists, 18.3% report they always wear their helm
et when bicycling. Persons between the ages of 18 and 24 years had the
highest proportion of bicycle riders for any adult age group (31.3%)
but reported using helmets less than any other adult age group (5.1%).
In univariate and multivariate analyses, age older than 24 years, fem
ale sex, higher educational level, and living in the west or northeast
region of the country were associated with helmet: use among adults.
Helmet users were also more likely than nonusers to report a higher pr
evalence of other safety behaviors (ie, always wearing a safety belt,
having a smoke detector in the house, and having a fire escape plan).
Further efforts to increase the wearing of bicycle helmets by adults a
re necessary to meet the year 2000 objective of 50% helmet use. Adults
should be targeted for increased helmet promotion efforts, especially
those between the ages of 18 and 24 years. Increasing consistent use
of helmets among adults may also help increase consistent use of helme
ts among children through role modeling.
