The latest federal look at teenage behavior is reassuring and suggests that some safety messages are getting through to American youth.
On the downside, kids are fatter than ever before and just a third are eating anywhere near as many fruits and vegetables as they need to stay healthy. And less than a third are getting enough sleep.
And a very troubling new statistic shows that more than 40 percent of teenagers who drive cars admit to having texted or emailed while driving recently.
But on the whole, it's a snapshot of progress. The Centers for Disease Control and Prevention, which organizes the every-other-year survey, was especially pleased about the drop in smoking.
"I think it's really encouraging that we're seeing the lowest cigarette smoking rate ever," CDC director Dr. Tom Frieden told NBC News.
"We've actually reached the goal that the nation set for ourselves for 2020 early. So that's one of the most positive trends that we see here — down to 15.7 percent — less than one out of six kids in our high schools is smoking. That's great news."
