A new study finds that going to bed late during adolescence is associated with an increase in body mass index over time. Researchers analyzed data from over 3,000 participants and found a significant link between later bedtimes and higher BMI. The study highlights the importance of adolescent bedtime habits in weight management.
A cognitive-behavioral prevention program for depression among at-risk youth showed benefit over 6 years after implementation, reducing depression incidence and promoting competence. The program's effects were seen in youths whose index parent was not depressed at enrollment.
A world-first trial by the University of Melbourne has successfully reduced risk-taking behavior in teenagers through trained doctors. The study found that after discussions with GPs, young people reported fewer instances of illicit drug use, sexually transmitted illnesses, and unplanned pregnancies.

The study suggests that cumulative experiences of discrimination, particularly during adole...
A recent study published in JAMA Pediatrics has revealed a significant association between e-cigarette use and the progression to traditional cigarette smoking among adolescents and young adults. The study found that nearly 70% of e-cigarette users progressed towards smoking, while only 18.9% of non-users did so.
A study published in JAMA Pediatrics found that survivors of child trafficking experienced physical and/or sexual violence, depression, anxiety, and PTSD. Mental health symptoms were associated with self-harm and suicide ideation among the 387 children and adolescents surveyed.
A new Duke University study reveals that adolescents aged 10 to 16 can be more analytical in their economic choices than slightly older young adults. Researchers found that teens carefully weigh decisions, using cost-benefit analysis skills, while young adults rely on simple rules.
Research from University of Cambridge found that extra hour of daily screen time in Year 10 is associated with 9.3 fewer GCSE points at age 16, while pupils doing an extra hour of homework and reading performed significantly better.
A new study finds that high school students lose an average of 32 minutes of sleep per night following the springtime change to daylight saving time. This leads to increased daytime sleepiness and decreased vigilance, posing a risk to teen drivers. The study suggests that this can further restrict their already limited sleep schedules.
A new study suggests that maintaining close relationships with peers in adolescence can have long-term benefits for adult physical health. The research found that both high-quality friendships and a drive to fit in with peers were associated with lower anxiety, depressive symptoms, and improved overall health.

A new study found that higher-quality romantic relationships are associated with fewer psychosocial difficulties across adolescence and young adulthood. The quality of the relationship, not just having one, is key to better psychosocial adjustment.
Teens who use e-cigarettes are more likely to start smoking combustible tobacco products, according to a recent study. The study found that e-cigarette users were 31% more likely to report using combustible tobacco within six months of using e-cigarettes.
An imaging study found that early adversity during childhood is associated with altered brain structure in late adolescence, including lower gray matter volume in a key brain region. Higher levels of internalizing symptoms, such as depression and anxiety, were also linked to this altered brain development.
A Mayo Clinic study published in Pediatric Obesity found that excessive vitamin D supplementation in obese teenagers showed no benefits for their heart health or diabetes risk. The study, led by Dr. Seema Kumar, also found increased cholesterol and triglyceride levels in the teens during supplementation.
Researchers at KU Leuven found a molecular switch that controls how the brain compensates for vision loss, with implications for sensory prosthetics and patient recovery. In adult mice, this cross-modal neuroplasticity is triggered by both eyes and whiskers, but in adolescents, only one eye takes over.
Despite claims by Susan Greenfield that intense internet use harms adolescent brains, experts warn that there is currently no evidence to support these claims. Research suggests that social networking sites can enhance friendships and relationships, while computer games do not lead to impulsiveness or aggression.
A new study highlights the unique challenges of adolescent sibling stem cell donation, including health risks, pain, and psychological burdens. The authors argue that the role of siblings in providing life-sustaining stem cells has been taken for granted.
