Minnesota teens are drinking less and buckling up more.
The 2010 Minnesota Student Survey also found student marijuana use unchanged and more kids planning to attend college since the last survey of sixth-, ninth- and 12th-graders, which has been conducted every three years since 1992.
Smoking and binge drinking also were down from 2007. The percentage of high school seniors who said they'd had five or more drinks in a row during the past two weeks dropped from 29 percent in 2007 to 23.4 this year.
"It seems like a lot of things are trending positively, even though we're probably not satisfied with some of the percentages," said state Education Commissioner Alice Seagren. "It's still not acceptable to have 23 percent of our 12th-graders binge drinking. We don't want any of our students binge drinking."
Seniors who reported drinking in the past year dropped from 63 percent in 2007 to this year's 55 percent.
Seagren warned that the survey provides only a rough snapshot of teen behavior. For one thing, the schools that participate can change from one survey to the next. Also, because students participate voluntarily and anonymously, there's no way of knowing how accurately they're reporting their own behavior.
"You have to take it with some grains of salt," Seagren said. "Maybe kids are not filling in all the answers to the questions. You might get 100 percent answer one question, and 50 percent answering another. You might have kids faking it and not giving a true answer. There are some limitations to the survey."
The survey also shows there are still plenty of kids indulging in risky or unhealthy behavior.
