Despite their precious cargo, parents are no less likely to engage in driving distractions like cell phone use than drivers from the general population, according to a new University of Michigan study published in Academic Pediatrics.

The study found that 90 percent of parent drivers said they engaged in at least one of the 10 distractions examined in the study while their child was a passenger and the vehicle was moving, says lead author Michelle L. Macy, M.D., M.S., an emergency medicine physician at the University of Michigan’s C.S. Mott Children’s Hospital.

The study, conducted in two Michigan emergency departments, showed about two-thirds of the study respondents said they’ve talked on cellular phones while driving their child, consistent with other studies in the general population. About 15 percent of the study respondents said they’ve texted while driving their child.

But, importantly, drivers in this survey admitted to other distractions, such as giving food to their child more frequently than they disclosed talking on a cellular phone, Macy says.

“This just highlights the need to consider multiple sources of driver distraction when kids are passengers. Giving food to a child or picking up a toy for a child not only requires a driver to take their hands off the wheel but also take their eyes off the road,” Macy says.

Each year, more than 130,000 children younger than 13 are treated in U.S. emergency departments after motor-vehicle collision-related injuries. About one in six fatal motor-vehicle collisions in the U.S. in 2008 resulted from driver distraction, and Macy says that over time that percentage has likely increased.

Researchers also found that those parents with higher education and who were non-Hispanic whites were more likely to report cellular phone and directions-related distractions like use of navigation systems.

“If this finding is a result of greater access to technology among more highly educated and non-Hispanic white parents, we can expect the problem of techonology-based distractions to expand because national rates of cell phone ownership in the U.S. have climbed above 90 percent,” Macy says.

The study was conducted by faculty from the U-M Medical School, School of Public Health and the U-M Injury Center.

The study was conducted at the University of Michigan C.S. Mott Children’s Hospital pediatric emergency department, located in Ann Arbor, Mich., and the Hurley Medical Center emergency department located in Flint, Mich. The U-M location serves a predominantly white, privately insured population and the Flint location has a higher proportion of African American patients covered by Medicaid compared with U-M.

The study is based on responses of 570 parents of 1 to 12 year old children who arrived in the emergency departments of the two hospitals.

Whether a driver engaged in a distraction also was significantly associated with the age of the child, Macy says. Odds of reporting a child-related distraction was higher among parents of children between the ages of 2 and 8 than among parents of 1-year-olds.

Macy says she is concerned as well about whether parents are modeling the right behaviors in front of children who will eventually learn to drive.

“We know there are some limitations to this study, especially that people are often reluctant to disclose that they engage in dangerous, and in the case of text messaging in Michigan, illegal behaviors while driving,” says Macy.

“But our results do highlight the fact that child passengers are frequents being exposed to the risks of distracted driving.

“Efforts to improve child passenger safety have often focused on increased and proper use of restraining seats. But this study shows that reducing distractions and discouraging unsafe behaviors could prevent crashes.”
