Abstract
ObjectiveTo determine the prevalence of smoking among drivers of private vehicles in the city of Lleida (Spain). MethodsA random sample of 1600 cars passing through six intersections regulated by traffic lights were selected. The variables were age, sex, smoking driver, adult passengers, intersection (urban/interurban), day (working day/weekend), hour (morning/evening) and simultaneous smokers. We calculated the prevalence of smoking drivers and the corresponding odds ratios (ORs), adjusted for the potential confounding variables, as well as their 95% confidence intervals (95% CI). ResultsThe prevalence was 6.0% (95% CI: 4.9-7.3) and was higher in men (6.4%), in the group aged 41 to 60 years (6.9%), and in unaccompanied drivers (6.5%). The probability of the driver smoking increased if there was a smoking passenger (aOR=10.8; 95% CI: 3.6-32.5). The frequency of smoking drivers was higher on working days (aOR=1.7; 95% CI: 1.0-2.8) and in the morning (aOR=1.6; 95% CI: 1.0-2.4). ConclusionsThe prevalence of smoking drivers can be considered dangerously high. We recommend avoiding smoking while driving.
