[BDSP. Notice produite par INIST-CNRS UR0xR5S3. Diffusion soumise à autorisation]. Objective To investigate the association between risk of motor vehicle driver injury and body mass index (BMI). Methods In a cohort study of 10 525 New Zealand men and women, BMI was assessed in 1992-1993 (baseline), and data on deaths and hospitalizations for motor vehicle driver injury were obtained by record linkage to national health databases for the period 1988-1998. Hazard ratios (HR) and CI were estimated by Cox regression. Results During a mean 10.3 years of follow-up, 139 fatal and non-fatal driver injury cases occurred (85 before baseline and 54 after). A U-shaped association was observed between driver injury risk and BMI, both crudely and after adjustment for covariates, which included age, sex, driving exposure, and alcohol intake (P-values for quadratic trend=28.7 kg/m2 ; HR=2.00,95% CI : 1.18-3.39) and lowest (
