AIM: The aim of this study was to clarify the prevalence and influencing factors of rear seat belt use among pregnant women.
METHODS: Questionnaires were given to 1546 pregnant women who visited obstetrics clinics and hospitals for prenatal checkups from October to December 2013. A total of 1494 pregnant women (96.6%) agreed to participate in this study and completed the questionnaire.
RESULTS: Fewer than 20% of the rear-seat passengers 'always' used seat belts before and during pregnancy, whereas a third 'never' used a seat belt before or during pregnancy. There was no significant decrease in seat belt use by rear-seat passengers during compared to before pregnancy. Multivariate analysis revealed that age, knowledge of how to use a seat belt during pregnancy, belief in the compulsory use of a rear seat belt and driver behavioral characteristics before pregnancy were associated with rear seat belt use during pregnancy.
CONCLUSIONS: The prevalence of fastening seat belts was substantially low. The provision of information regarding proper seat belt use and its role in protecting the fetus may increase use.
