Adolescents worldwide are spending an average of 8 to 10 hours per day engaging in sedentary activities such as watching television, using electronic devices, playing video games and riding in motorized vehicles, according to a multinational study.

Novel research shows that a reduced neural response to receiving rewards in teens predicts the first onset of depression, but not anxiety or suicidality. This is independent of pre-existing depressive or anxiety symptoms, as well as age or sex, which are already strong risk factors for depression. The study is a step toward using brain science to understand and assess mental health risks.

A new study suggests that boosting adolescent mental health is linked with long-term economic benefits. In contrast to similar findings from prior studies, these estimated relationships could be readily incorporated into standard government budgeting analyses for assessing potential policy impacts

Teens who think their parents use cannabis are more likely to hold favorable attitudes toward the drug and to consider trying it themselves, according to a new study. The research also reveals that parental monitoring and the closeness of parent-child relationships play crucial roles in adolescents' views about cannabis, often with distinct effects based on the parent's gender.

Research has shown that a biological brain mechanism called the 'kynurenine pathway' is imbalanced in adolescents with depression, and this imbalance is more pronounced in teenage girls than boys

Researchers explored the long-term effects of preschool expansion in Japan in the 1960s, revealing significant reductions in risky behaviors amongst teenagers. By analyzing regional differences in the rollout of the program, the study identified links between early childhood education and lower rates of juvenile violent arrests and teenage pregnancy. The findings suggest that improved noncognitive skills played a key role in mitigating risky behaviors, highlighting the lasting benefits of early-education policies.

A new study found a strong association between handheld cellphone use and risky driving behaviors among newly licensed teen drivers. The study used a smartphone telematics application to track the driving habits of hundreds of teens and identify potential safety risks.

A recent study found that good physical fitness from childhood to adolescence is linked to better mental health in adolescence. These results are significant and timely, as mental health problems are currently a major societal challenge, affecting up to 25%--30% of young people. These findings suggest that improving physical fitness from childhood can help prevent mental health problems.

Depression in young teens could be easier to treat than in adulthood due to the symptoms being more flexible and not yet ingrained, a study shows.

A new study suggests that boys who become overweight in their early teens risk damaging the genes of their future children, increasing their chances of developing asthma, obesity and low lung function.
