If you made a New Year's resolution to lose weight but find yourself falling off of the workout routine, a study conducted by Berkeley School of Health might give you an extra incentive get back in the gym. In conjunction with the Centers for Disease Control and Prevention's (CDC), UC Berkeley’s Safe Transportation and Research Education Center (SafeTREC) decided to conduct a study on whether or not obesity played a factor in motor vehicle fatalities.
Though the study was published in 2013, this information is even more relevant in 2017 as 1 in every 3 Americans are obese, and since obesity in general is steadily on the rise. The study's results showed that obese drivers are actually 78% more to die in a car crash compared those in the normal-weight category. So, yes, obesity is definitely a factor in car crash deaths.
Co-author and SafeTREC researcher epidemiologist Thomas Rice said, “This study highlights yet another negative consequence of obesity.”
The Higher The BMI, The Higher The Chance of A Car Crash Fatality
Drivers with a body mass index (BMI) under 18 or between 25 to 29.9 are found to have around the same fatality rates as those people with an ideal BMI ranging from 18.5 to 24.9. The problem comes in for those who have a BMI ranging between 30 and 39.9. Those whose BMI falls between 30 to 34.9 have a 21% increase in risk of death as stated by the SafeTREC’s study. The study also showed that those with a BMI between 35 to 39.9 increase their fatality rates by 51%. Obese drivers with a BMI above 40 have a 81% possibility of death in the event of a motor vehicle fatality. SafeTREC's study also confirmed that woman who are obese are more likely to die in a car crash than their male counterparts.
In simpler terms, if a male driver was the nation's average male height of 5 feet 9 inches and weighed the national male average of 195.5 pounds with a BMI of 28.5, he would essentially face the same mortality rates as a male that weighs 158 pounds at 5 feet 9 inches with a BMI of 23. However, if a male that was 5 feet 9 inches weighed 220 pounds with a BMI of 32, he increases his chances of death by 21%.
Vehicle Changes Made For Overweight Drivers
Researchers of the study suggest that,“it may be the case that passenger vehicles are well designed to protect normal-weight vehicle occupants but are deficient in protecting overweight or obese occupants.”
Rice said, “Vehicle designers are teaching to the test –designing so that crash-test dummies do well, but crash-test dummies are typically normal size adults and children. They’re not designed to account for our nation’s changing body types.”
Now changes are underway starting with vehicle safety and design through test-dummies that are heavier in size to reflect the nation's growing weight. Michigan Medicine trauma surgeon Stewart Wang, M.D., is a collaborator on car safety as the director of the University of Michigan's International Center for Automotive Medicine (ICAM). Dr. Wang offers some perspective to engineers who are designing a safety mechanism that will later be placed into vehicles.
The surgeon says, "crash-test dummies look nothing like my patients...The condition, size and shape of an individual is hugely important in how severe their injuries are in any given crash." Dr. Wang also says that many of his obese clients suffer from lower extremity injuries in auto accidents as a result of the lap belt being too slack and causing them to slide under it upon impact. These types of injuries combined with, "their obesity makes treatment more difficult and delays recovery." Wang's medical research of live patients have provided ICAM with vital information which was used in the creation of new test dummies by manufacturer Humanetics, so that engineers can better interpret potential injuries to drivers of a certain weight, sex, and age.
According to ScienceDaily.com, "Teams at ICAM gain tremendous insight from hundreds of thousands of CT scans, which can quickly be used for 3-D printing of prototypes once they're shared with engineers. This has revolutionized the way dummies are made and what they look like."
With scientific research highlighting the importance of test-dummies reflecting the nation's growing population of overweight and elderly drivers, changes can finally be made to vehicles that lead to lower rates auto accident fatalities, for all ages and body types.
According to the CDC, obesity can be combated through local and state programs that work with communities in creating an environment that encourages healthy eating and physical activity. Living a healthy lifestyle including a lifetime commitment to eating healthy and exercising should help those combating with obesity lose and keep off their weight.
