New Jersey's latest student health survey finds fewer students are drinking alcohol, smoking cigarettes and using drugs.
But the number of students who say they were bullied hasn't changed since 2009 and many students continue to talk or text on cellphones while driving.
The 2013 results show 39 percent of students surveyed had at least one drink of alcohol in the last 30 days, down from 56 percent in 2001.
Thirty-nine percent of students in 2013 said they had sexual intercourse, down from 47 percent in 2001. Of those, 41 percent did not use condoms.
The percentage of students classified as overweight or obese has not changed significantly since 2001.
The survey was completed by 1,701 students in 31 high schools across New Jersey.
