A cohort study with prospective and retrospective outcomes JO - International journal of epidemiology A1 - Whitlock, G. A1 - Norton, R. A1 - Clark, Tony A1 - Jackson, Rodger A1 - Macmahon, S.

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/m(2); HR = 2.00, 95% CI: 1.18-3.39) and lowest (<23.5 kg/m(2); HR = 2.17, 95% CI: 1.27-3.73) quartiles of BMI were twice as likely to have experienced a driver injury during the follow-up period as participants in the reference quartile (25.9-28.6 kg/m(2); HR = 1.00). CONCLUSION: Further research is needed to corroborate or refute the hypothesis that BMI is a risk factor for serious motor vehicle driver injury.
