Samenvatting

Few studies have looked at how obesity affects injury outcomes among vehicle occupants involved in traffic collisions. To estimate the association of obesity with death risk among drivers of passenger vehicles aged 16 or older and to examine effect modification by driver sex, driver seat belt use, vehicle type and collision type. A matched-pair cohort study was conducted using data from the Fatality Analysis Reporting System. WHO body mass index (BMI) categories were calculated. Data were analysed using conditional Poisson regression. Estimated risk ratios (RRs) were slightly raised for underweight drivers (RR=1.19, 95% CI 0.86 to 1.63). RR increased with higher BMI categories and were 1.21 (0.98 to 1.49) for BMI 30-34.9, 1.51 (1.10 to 2.08) for BMI 35-39.9 and 1.80 (1.15 to 2.84) for BMI 40 or over. Estimated BMI effects varied by gender. No meaningful variation was found across levels of vehicle type, collision type or seat belt use. Findings from this study suggest that obese vehicle drivers are more likely to die from traffic collision-related injuries than non-obese occupants involved in the same collision. Education is needed to improve seat belt use among obese people, as is research to understand the potential role of comorbidities in injury outcomes. (Author/publisher)
