Increasing seat belt use represents an ideal opportunity for preventive health care in family practice. Little evidence exists, however, that primary care physicians can increase safety belt use.
Three hundred twenty-six patients seen in a rural primary care center were randomized to either a control or intervention group. Before their health care examination, patients completed a short questionnaire concerning seat belt use and then viewed a 6-minute videotape explaining reasons to wear seat belts (intervention) or espousing general preventive health care guidelines with no mention of seat belts (control). In 6 months the questionnaire was again administered with no further intervention.
Two hundred forty-three (74.5 percent) patients completed both baseline and 6-month questionnaires. Seat belt use increased significantly from baseline to 6 months for the intervention (22 to 37.3 percent, P = 0.00052) and control (20 to 33.6 percent, P = 0.00085) groups; however, the difference between the increase in the intervention (37.3 percent) and control (33.6 percent) groups at 6 months was insignificant (P = 0.641). The most common reasons for not using seat belts were forgetfulness (40.3 percent), fear of being trapped (26.7 percent), and lack of comfort (21.8 percent).
Seat belt use increased in this study, although the intervention videotape was no better than the control videotape at increasing restraint use. This increase in use supports office-based intervention to improve seat belt use, but further research is needed to clarify the mechanism and extent of change possible.
