The U.S. Centers for Disease Control and Prevention (CDC) issued the Youth Risk Behavior Surveillance report for 2013 this week. The report identifies risky behaviors in American youth in order to identify and mitigate behaviors that currently contribute most to causes of illness, injury, and death in youth and young adults.

Many of the risky behaviors have declined in prevalence since the last report, such as  cigarette use, sexual activity, and physical fighting. Other behaviors have stayed the same or increased. Some of the behaviors that have stayed the same are marijuana use, suicide attempts, and drug and alcohol use before sex. Safety concerns at school and unhealthy weight prevalence have increased.

According to Reuters, the study indicates that texting while driving is also prevalent in teenagers. While teenagers smoking hit an all-time low at 15.7 percent in 2013, more than 40 percent of students who have driven a car in the previous 30 days said they sent text messages or emails while driving. The 2013 survey was the first to collect information on texting while driving, establishing a baseline for future research.

The CDC also breaks down data into a number of specific topics. For example, trends for 1991 to 2013 are offered for various topics and sub-topics. Obesity, dietary behaviors, and weight loss have trends for the studied period, but the trends cover more than just the prevalence of obesity or overweight. Trends are also available for eating fruits, eating vegetables, drinking milk, drinking soda, eating breakfast, and anorexic and bulimic behaviors. Data is also available by state.
