DEAR DOCTOR: My husband and I have a running battle with two of our three kids, who have zero interest in anything that isn’t on a screen. They’re 11 and 13, so rational arguments about their adult health don’t work. Just how important is it for kids to get regular exercise?

DEAR READER: Children need a certain amount of physical activity in their lives for optimum health. Decades of research have (repeatedly) shown that adults who are physically fit have a decreased risk of developing chronic illnesses and conditions like heart disease, stroke, cardiovasc­ular disease, certain cancers and diabetes. And physical fitness also plays a role in improved mood and can help with depression.

Now, thanks to recent reviews of existing research, we’re learning that those of us who were physically fit as children are more likely to be fit — and healthy — as adults. Yet at the same time, data show that adolescent­s today are up to four times as likely to be overweight as they were in 1960. Fewer than half of children between the ages of 9 and 13 engage in organized physical activity outside of school. Onefourth don’t take part in any free-time physical activity at all.

Current exercise

guidelines for children aim for a minimum of 60 minutes of activity per day, with aerobic exercise the gold standard for cardiovasc­ular health. Walking, hiking, skateboard­ing, running, biking, dance, gymnastics and many team sports can get the heart pumping. Activities to strengthen muscles as well as controlled impact activities like jumping rope, hopscotch or running that help build bone are important.

One of the keys to getting kids off the couch is to model the desired behavior yourselves. Make physical activity a family priority. Family hikes with a picnic at the destinatio­n, a basketball hoop in the driveway, games of tag or catch, jumping rope and family bike rides are great ways to get everyone moving. The trick is to start small, build slowly and make it fun. And know that you’re in it for the long haul.
