Abstract
A survey of cyclists was conducted in Ottawa in September 1988 to determine the use of protective helmets. The survey observed 1963 cyclists, of whom 211 (10.7%) wore helmets. The highest level of helmet use was found among older, commuting cyclists (17.9%), followed by recreational cyclists (14.3%). Overall helmet use among students was found to be very low (1.9%), and differed significantly (p>0.0001) from the other two groups, which consisted almost entirely of adults. The author conclude that childern and young adults are the least likely groups to wear helmets while cycling. The five to 19 age group, however, suffer the most cycling injuries, particulary head injuries.
