[Estimation of the use of seat belts: an observational study and a telephone survey]
1Programa de Epidemiología Aplicada de Campo (PEAC), Instituto de Salud Carlos III, Ministerio de Sanidad y Consumo.
Objective:
To estimate the prevalence of safety-belt use in a telephone survey and an observational survey.
Patients And Methods:
Observational survey. Trained interviewers studied 4,067 front-seat occupants, at ten intersections of Madrid, according to "National Highway Traffic Safety Administration" guidelines. TELEPHONE SURVEY: We selected 433 front seat occupants from the Madrid city residential telephone directory. The questionnaire was completed by trained interviewers.
Results:
Prevalence by the observational survey was 58.5%, and was significantly higher at interurban intersections (OR = 2.1) than city intersections. In the telephone survey, the overall prevalence was 94% at interurban area and 64% at city area and it was associated with no history of lines and positive opinion of effectiveness of safety belts.
Conclusions:
The safety belt prevalence observed is low, especially in the urban area. The telephone survey overestimates the safety belt use, but contributes with useful information for planning strategies.
