What Doctors Know: New survey offers inside look at risky behavior among today’s teens
By Larry Myers and Bonnie Jean Thomas, WHAT THE REPORT FOUND
“When I was your age…”
There’s a certain time in our lives — somewhere between being a parent and a grandparent — when we look at today’s generation and come to the conclusion: “Kids were different in our day.”
Generation after generation continues to come to this conclusion, but with little supporting data. Well, that supporting data has finally arrived. The U.S. Centers for Disease Control and Prevention conducted a yearly study of teenage behavior that could supply answers to questions we’ve been asking about “youngsters” for generations.
The Youth Risk Behavior Survey (YRBS) consists of 86 standard questions, focused on behaviors of teens across the country.
Taking a sampling of teens from regular public and private schools with students in at least one of grades 9-12 in the 50 states and the District of Columbia, the study reviewed a number of behaviors, as well as the leading causes of death among youth and adults in the U.S. The report broke down all the data using six categories of health-risk behaviors:
1. Behaviors that contribute to unintentional injuries and violence
2. Tobacco use
3. Alcohol and other drug use
4. Sexual behaviors that contribute to unintended pregnancy and sexually transmitted infections (STIs), including HIV infection
5. Unhealthy dietary behaviors
6. Physical inactivity
These behaviors frequently are interrelated and established during childhood and adolescence years and extend into adulthood. To monitor priority health-risk behaviors in each of these six categories and obesity and asthma among youth and young adults, the CDC developed the Youth Risk Behavior Surveillance System (YRBSS).
In the U.S., 70 percent of all deaths among youth and young adults aged 10-24 years result from four causes:
1. Motor vehicle crashes (23 percent),
2. Other unintentional injuries (18 percent),
3. Homicide (15 percent), and
4. Suicide (15 percent)
Also alarming among youth 15-19 years, are the social problems resulting from:
— An estimated 329,772 births
— 548,032 cases of chlamydia, gonorrhea and syphilis
— And 2,240 cases of human immunodeficiency virus (HIV) reported annually.
— Among adults aged less than 25 years, 57 percent of all deaths in the U.S. result from cardiovascular disease (33 percent) and cancer (24 percent).

OTHER HEALTH-RELATED TOPICS

Nationwide, 31.7 percent of students got 8 or more hours of sleep on an average school night.
What conclusions can we draw from all this information? While things may be considerably different today than they were “back in the day,” having access to resources such as YRBSS is a step in the right direction to understanding the needs of our youth so we can focus our efforts on protecting and promoting the health of future generations.
