Since 1991, The U.S. Center for Disease Control has surveyed teens every two years in order to identify trends in risky adolescent behaviors. The results of the 2009 Youth Risk Behavior Survey have just been released.

First, let's look at the percentages on some of the areas surveyed:

• Have had at least one drink of alcohol (during their life): 72.5%, down from 75% in 2007.
• Have had at least one drink within 30 days of the survey: 41.8%, down from 44.7% in 2007.
• Have had five or more drinks within a few hours, within 30 days of survey: 24.2%, down from 26% in '07.

• Have used marijuana at least once (during their life): 36.8%, down from 38.1% in 2007.
• Have used marijuana at least once within 30 days of the survey: 20.8%, up from 19.7% in 2007.

• Have tried cigarette smoking (during their life): 46.3%, down from 50.3% in 2007.
• Have smoked cigarettes at least once within 30 days of the survey: 19.5%, down from 20% in 2007.

• Have had sexual intercourse (during their life): 46%, down from 47.8% in 2007.
• Have had sexual intercourse with 4 or more persons (during their life): 13.8%, down from 14.9% in '07.
• Have had sexual intercourse within 30 days of the survey: 34.2%, down from 35% in 2007.
• Drank alcohol or used drugs before last sexual intercourse: 61.1%, down from 61.5% in 2007.

• Seriously considered attempting suicide during 12 months before survey: 13.8%, down from 14.5% in '07.
• Made a plan about how they would attempt suicide during 12 mos before survey: 10.9% down from 11.3% in '07.
• Attempted suicide during 12 mos before survey: 6.3%, down from 6.9% in 2007.

• Rarely or never wore a seat belt: 9.7%, down from 11.1% in 2007.
• Rode with a driver who had been drinking within 30 days of survey: 28.3%, down from 29.1% in 2007.
• Drove when drinking alcohol within 30 days of survey: 9.7%, down from 10.5% in 2007.

While on the surface it appears that there are broad, although slight decreases in at-risk behaviors, the study indicates that in terms of trends, most changes are statistically insignificant, amounting to "no change." The areas noted above where changes in trends were indicated were:

• Have had at least one drink within 30 days of the survey - decrease
• Have tried cigarette smoking (during their life) - decrease
