Sharon Kardia: Genomics in the Health & Retirement Study
Kallan, M.J., K.B. Arbogast, Michael R. Elliott, and D.R. Durbin. 2009. "Non-fatal and fatal crash injury risk for children in minivans compared with children in sport utility vehicles." Injury Prevention, 15(1): 8-12.
Objective: To compare the fatal and non-fatal crash injury risk for children in minivans compared with midsize and large sport utility vehicles (SUVs). Design: Three large population-based sources of US crash data were used-a nationwide cohort of sampled police-reported crashes (NASS-CDS) along with a census of fatal crashes (FARS), plus a large child crash surveillance system, Partners for Child Passenger Safety (PCPS)-collected in 16 states via insurance claim records and validated telephone survey. Each included: 2000-2006 data, occupants aged 0-15 years, traveling in minivan or (midsize/large) SUV, model year 1998-2007. Outcome of interest was parent/driver report of non-fatal injury (Abbreviated Injury Scale scores of 2 or higher) in PCPS and fatal injury in NASS-CDS/FARS. Results: Compared with children riding in SUVs, those in minivans experienced a similar crude reduction in the relative risk of non-fatal injury (PCPS: unadjusted odds ratio (OR) = 0.55) and fatality (NASS-CDS/FARS cohort: unadjusted OR = 0.58). In PCPS, this reduction in injury risk changed little after adjustment for child, driver, and vehicle factors (adjusted OR = 0.56, 95% CI 0.38 to 0.82). Lower fatality risk in the NASS-CDS/FARS cohort was partially explained by the same factors (adjusted OR = 0.76, 95% CI 0.51 to 1.13). Conclusions: There may be important safety differences in vehicles during a crash that lead to fewer non-fatal injuries to child occupants of minivans compared with SUVs.
