A recent study found that 15% of African-American youths at risk of dropping out of school reported carrying a gun, with regular carriers more likely to be involved in selling drugs or fighting. The study suggests that carrying a gun may indicate a more serious pattern of behavior, rather than just another risk factor.

This suggests that condoms may be an effective means of preventing HIV/STDs and pregnancy when used by those who are already sexually active.
A study found that one-third of young adults who outgrow asthma may experience a relapse by age 26. Those highly allergic or with bronchial hyper-responsiveness are at greatest risk. The study followed 1,037 New Zealanders to age 26, with detailed respiratory histories every two years.

Fatalities due to fires, submersions, or falls were common among young children, with African-American children facing disproportionately higher risks.
A recent study found that adolescent girls who consumed more calcium on average weighed less than those who consumed less calcium. The researchers discovered that an increase in one serving of dairy products or supplements resulted in a significant reduction in weight and body fat.
A study published in JAMA found that sibutramine, a weight loss medication, helped obese adolescents lose an average of 17.2 pounds when used in conjunction with a behavior modification program. The study also showed improvements in insulin levels and a reduction in weight regain over time.

Adolescents who viewed religion as meaningful and a way to cope with problems were half as likely to use drugs. The effect was consistent across different ethnic groups, suggesting that religiosity provides a buffering impact against substance use.
A new study finds that children in low-income families are not harmed when their mothers leave welfare and enter the workforce. The research also suggests that mothers' entry into the labor force is related to improvements in adolescents' mental health, while exits from employment are linked to increased behavior problems.
A Canadian Medical Association Journal study found that 15% of Ontario students with driver's licenses reported driving under the influence of alcohol, and 20% admitted to driving after using cannabis. These findings are particularly concerning given the high incidence of alcohol-related motor vehicle collisions among adolescents.

A study published in Child Development found that teenagers in high-use schools are three times as likely to follow their peers' smoking behaviors compared to those in low-use schools. The researchers suggest that school-based programs may be effective in reducing tobacco and alcohol use among teens.
A study of 444 managed-care patients aged 12-17 found that adolescents with consistently monitored parents were less likely to engage in alcohol-risk behaviors. The researchers suggest that monitoring may help reduce risk when adolescents are initially exposed to alcohol, but may be insufficient for high-risk behaviors.
Adolescents with two smoking parents are 3.8 times more likely to smoke than those with both non-smoking parents. Quitting smoking by parents can reduce the likelihood of their adolescent smoking, especially when both parents are non-smokers.
