According to a study of data accumulated by the National Highway Traffic Safety Administration (NHTSA), obese drivers have a higher probability of dying in a car crash than those who are of normal weight. In fact, their chances of death in an accident are 80% higher than those who weigh less.
Transport safety researchers Thomas Rice and Motao Zhu related their findings in an online publication of the Emergency Medicine Journal.
Since one out of every three American adults is considered to be obese, this new study is alarming. Interestingly, the study revealed that obese females were at an even higher risk of being a car crash fatality than their male counterparts.
Time will only tell whether this study will invoke changes by automobile manufacturers to make vehicles safer for obese drivers.
The study that covered a 12 year period from 1996 to 2008, examined 57,500 car crashes. The data included all of the deaths that occurred within 30 days of the accidents.
One finding illustrated the fact that obese vehicle occupants in general had a host of other health problems that reduced the probability of surviving a serious injury. The other finding was that seat belts do not properly interact with the human body when one is obese. Simply put, the lower body of an obese driver continues to go forward in a crash while the upper body is held back. This is because the excess padding and abdominal fat cause a delay in the time it takes to tighten against the pelvis.
Obesity was determined by body mass index (BMI). A BMI of 30 and over is considered to be obese. A BMI of 18.5 is considered to be normal.
Some conclusions reached were:
• A driver with a BMI of 30 to 34.9 was 21% more likely to die in a crash than a driver with a normal BMI.
• A driver with a BMI of 35 to 39.9 was 51% more likely to die in a crash than a driver with a normal BMI.
• A driver with a BMI of 40 or higher was 80% more likely to die in a crash than a driver with a normal BMI.
Another finding in the study was that underweight men were more likely to die in a crash than those with a normal BMI. Underweight men were those with a BMI of less than 18.5.
