The researchers analyzed survey data from over 140,000 middle and high school students and found no evidence that e-cigarettes have caused a decline in youth smoking
A new study reveals that obesity surgery has been shown to be as effective for teenagers as for adults, resulting in significant weight loss. However, the study also highlights potential complications, including bowel obstruction and gallstones, which require further monitoring and support.
A study by McGill University researchers found that students from schools starting earlier slept less and were more likely to be tired in the morning. Delaying school start times could help Canadian teenagers sleep better and give them a better chance for success.
Researchers find a positive correlation between belief in free will and happiness among Chinese teenagers, contrasting with previous Western studies. The study suggests that believing in free will may lead to increased perceived autonomy, self-control, and deliberate effort to achieve goals, ultimately contributing to happiness.
A new study from the University of Cambridge found that teenagers with mental health problems who receive treatment experience a greater decrease in depressive symptoms than those without. By age 17, service users were more than seven times less likely to report clinical depression compared to untreated individuals.
A study published in Addiction Biology found that long-term heavy drinking in adolescents alters brain electrical activity, particularly in the gamma-aminobutyric acid (GABA) neurotransmission system. This alteration may be detrimental to a developing brain, warranting tighter diagnostic criteria for substance abuse disorders.
A new study found that lap band surgery significantly improves weight and BMI in severely obese Australian teenagers, with median BMI reduction of 10 kg/m2. The procedure is a safe and effective option for adolescents with severe obesity, provided performed by an experienced surgeon and managed regularly.
A new study of over 120,000 UK teens found that moderate digital screen use is not linked to negative effects on well-being. The researchers suggest a 'digital sweet spot' where screen time benefits teens by providing opportunities for social connections and skills. However, excessive engagement may displace important activities.
Teenagers who play video games for more than four hours a day suffer from symptoms of depression, but frequent use of social media and instant messaging may mitigate symptoms of game addiction. Strong friendships appear to be a key factor in balancing out the negative effects of gaming.

Parents who do not trust their neighbors or feel they have no control over neighborhood problems are more likely to limit their child's physical activity.
A Johns Hopkins Medicine study found that social ecology influences on personal experiences and interactions with family, peers, and healthcare providers hinder young men's use of sexual and reproductive health care. Long wait times, costs, and concerns about privacy also deter seeking care.
Severely obese teenagers who undergo gastric bypass surgery experience significant weight loss and improved health outcomes, including reduced diabetes and high cholesterol risks. However, some patients may need additional surgery or develop vitamin deficiencies, highlighting the importance of long-term follow-up and support.

A new special section of Child Development explores the developmental course of violent offending, including factors such as emotion regulation skills and judgment. The research aims to inform novel practices and policies to prevent severe youth violence.
A study found that marijuana legalization significantly reduced perceptions of harm in eighth- and 10th-graders, but increased past-month use by 2-4% in Washington state. No change was seen in Colorado. The authors attribute the increase in teen use to reduced stigma and perceived risk after legalization.
A new study found that teen perception of marijuana's harmfulness decreased by 14.2% and 16.1% in Washington's 8th- and 10th-graders after recreational legalization, while marijuana use increased by 2.0% and 4.1%. No changes were seen in Colorado.
Research shows that brain maturation varies by individual and region, making it difficult to pinpoint a static baseline for maturity. Leah Somerville highlights the importance of considering brain development in policy-making decisions.
A new study found that adolescents are up to 183% more likely to carry out violent acts if their friends have also committed the same act. The contagion extends beyond friends to up to four degrees of separation, making it essential to stop violence in one person to prevent it from spreading to others.
A study of 3,063 children and adolescents with acute concussion found that physical activity within 7 days of injury was associated with reduced risk of persistent postconcussive symptoms. Engaging in early physical activity was linked to a lower risk of PPCS, regardless of intensity or exercise type.
Adolescents with autism face significant stress as they transition to adulthood, with difficulties in accessing services and adapting to change being major concerns. Social workers can play a vital role in supporting families by coordinating essential services such as medical treatment and independent living.

A new study found that children who spent more time on screen devices and watching television were more likely to engage in behaviors leading to obesity, including poor diet and lack of physical activity. The research suggests that limiting screen device use may be as important for health as limiting TV time.
Researchers found that N-acetylcysteine reduced both marijuana and alcohol use in treatment-engaged adolescents. The study's results suggest NAC may generalize to other substances and be useful in decreasing adolescent alcohol use.
A new study by UNC School of Medicine found that only 49.8% of surveyed teens consider cigar warnings 'very believable', highlighting the need for improved tobacco prevention campaigns. The survey, which included 1,125 adolescents aged 13-17, suggests that graphic warnings may be more effective in engaging youth.
A study of Israeli adolescents found that higher BMI in late adolescence and long-term cumulative burden of BMI predict poorer cognitive function later in life. Taller stature was associated with better global cognitive function, independent of socioeconomic position.
