Seat-Belt Use and Related Behaviors Among Young Adults

Abstract

Seat-belt use among young adults was examined to identify factors associated with nonuse. This research was part of the Dunedin Multidisciplinary Health and Development Study, which is a study of the health, development, and behavior of a birth cohort of young New Zealanders ( n = 1037). At age 21 years, 948 (93%) members of this cohort were administered a face-to-face interview where they were asked about seat-belt use (self and friends), reasons for nonuse, and also their involvement in risky driving practices, motor-vehicle traffic crashes, and some thrill-seeking activities. Results showed relatively high front seat-belt use (85–96%) but low rear use (29–47%). Some differences in use were a function of gender and seating location. Generally, users had higher academic qualifications and lower risky driving behavior (males only), but did not differ significantly as far as crash experiences and thrill-seeking activity was concerned. The main reasons for not using a seat belt were forgetfulness/laziness, a perceived low risk of injury, and discomfort. This study provided information about the background and behavior of young adults who do not use seat belts, which could be helpful when designing strategies to promote seat-belt use in this age group.
