Investigating Daylight Savings: The data on springing forward and falling back

Metric_clockThe vast majority of U.S. residents shifted their clocks back to standard time last weekend, effectively “gaining” an hour of time on Sunday. In my house, it meant that my early-rising daughter was up at 4:30 a.m.
instead of 5:30 a.m.! [Read more…]

What we know about kids and car seats

What we know about car seats and how kids use them

We have known for a long time that car seats save children’s lives. But even with that knowledge, do parents and caregivers use them appropriately?

A new study by researchers at University of Michigan found that while most people use child restraints properly, many do not. The researchers analyzed data on more than 21,000 children observed in cars at gas stations, fast-food restaurants, recreation centers and child care centers from 2007 to 2009 using guidelines from the American Academy of Pediatrics.

They found 21  percent of children ages 4 and younger were not following the recommendations for sitting in car seats. Thirty-three percent of 4- and 5-year olds and 66 percent of 6- and 7-year-olds were not following the recommendations for using car seats or booster seats. And – the most precarious finding – 11 percent of children were not wearing seat belts or sitting in car seats at all. Children were especially likely to be completely unrestrained if they were driving with an adult who wasn’t wearing a seat belt or if there were four or more children in the car.

While the evidence on kids using car seats is not encouraging, there are some intervention programs proven to increase the use of child safety seats. One systematic review found strong evidence that child safety seat laws increase the use of safety seats. Programs that combine education with distribution of car seats, incentives for installing car seats correctly and stepped up enforcement of laws also increase the use of car seats.

The bottom line: Car seats help save kids lives. It’s important to use them as recommended by the American Academy of Pediatrics.

Real evidence linking taxes and death

With U.S. income taxes due today, there will surely be banter around water coolers across the country on the subject of taxes, including a myriad of jokes about paying Uncle Sam.

“If my business gets much worse, I won’t have to lie on my next tax return.”

“When it comes to taxes, there are two types of people. There are those that get it done early, also known as psychopaths, and then the rest of us.”

“Drive carefully. Uncle Sam needs every taxpayer he can get.”

It turns out, there’s actually something to that last one.

A study in the most recent issue of the Journal of the American Medical Association, reviewed data on fatal road crashes from the National Highway Traffic Safety Administration from the past 30 years. The study found there are consistently more fatal car crashes on Tax Day each year, compared with other days. On average there are 13 more deaths – approximately a 6 percent increase – compared with other days.

What is going on?  The study authors speculate that added stress of a deadline could lead to more distracted driving, or that people could be consuming more alcohol on tax day.  Whatever the reason, they suggest a public health campaign to remind people to drive carefully on Tax Day.
