Hovering Parents Making Kids Obese

A new study shows that "Helicopter Parents" or parents who tend to hover around their kids when they play may be making them obese.

 According to the study, when parents hover over the kids they tend to not play as much and become sedentary. My question is, what parenst are doing this? I understand when the kids are really little you need to supervise in a sense, but let the kids spread their wings a little. All I know is I would have loved to have my Mom try to keep up with me and my friends during a rousing game of  kick- the- can when I was a kid.
