I blogged and commented on asurvey earlier about Religion and America’s youth. This new article goes further into the analysis and states:
But while teenagers who are religiously involved fared well overall, the 2.5 percent of respondents who identified themselves as Mormon fared best when it came to traversing the choppy waters of adolescence. … when it came to measuring rates of sexual activity and drug and alcohol use, Mormon teenagers showed a greater willingness to adhere to the requirements of their faith.
The article connects the findings to the practice of “early morning seminary and included a few snippets from actual teenagers following it.(Another article on the same topic with informative tables but bad design.)
