Analyzing Severe Injury Risk for Crashes Nationally and Within Iowa
نویسنده
چکیده
Two logistic regression models were used in the comparison of Iowa and U.S. crashes. Of particular interest is the risk of severe injury for male and female drivers within three age groups: middle-age (3554), older (55-74), and elderly (75 and older). Within Iowa, male drivers have a higher risk of severe injury than female drivers (Odds Ratio = 1.15). However, nationally, male drivers have a lower risk of severe injury than female drivers (Odds Ratio = 0.85). Iowa drivers between the ages of 55 and 74 have the highest risk of severe injury, whereas nationally, drivers over the age of 75 have a greater risk. The differences in gender and age effects are discussed. Among the issues considered are the role of seatbelts in reducing injury and factors related to changes in driving patterns among older and elderly drivers.
