Research suggests that high consumption of these substances may negatively affect decision-making, reward-seeking behavior, and eating habits throughout adulthood.
A new study reveals that teenagers are slower to learn about their peers' preferences due to underdeveloped brain regions. The fusiform cortex and medial prefrontal cortex, responsible for understanding mental states, show ongoing development during adolescence, which may explain these differences.

A high percentage of adolescents in developed countries use dietary supplements for sports performance and immune system benefits. The study found that boys and girls cite similar reasons, with enhancing sport performance as the top reason among athletes and nonathletes alike.
The study found that annual well-visit rates among adolescents increased from 41% to 48% after the ACA, with significant gains among minority and low-income adolescents. The ACA's requirement for coverage of preventive services without a copay led to increases in the receipt of recommended services up to age 21.
Researchers found that exposure to community violence is associated with increased antisocial behavior in children and adolescents, regardless of pre-existing conduct disorder. The study suggests that prevention programs can help break the cycle of violence.

Penn State researchers recommend removing electronic devices from bedrooms, establishing bedtime routines, and avoiding bright lights to improve sleep in children and adolescents. The study suggests screen-based media consumption leads to delayed bedtimes, reduced total sleep duration, and negative effects on sleep quality.
Researchers found that nearly three-quarters of participants didn't develop problems with marijuana during young adulthood. The remaining quarter showed varying levels of limited, persistent, and delayed problems, often linked to childhood family conflict and instability. Anxiety disorders were a common issue among these users.
A large national sample of youth will be studied over several years to understand how sexual minority stress changes over time and its resulting health risks. The study aims to enable the development of targeted and effective behavioral health interventions to improve health outcomes for this vulnerable population.
A new study from UMass Amherst suggests that women who are underweight during adolescence or adulthood may be at increased risk for early menopause. The research, which followed nearly 80,000 women over 25 years, found a significant association between being underweight and an earlier onset of natural menopause.
Researchers from Lancaster University found that teenagers who do not access healthcare when needed are at greater risk of dropping out of high school. More than one in five young people globally experience this issue, leading to increased unemployment, poor health, and crime.
A new study found that parents who acknowledge their adolescent children's perspectives and encourage them to express themselves have youths with stronger self-worth, intrinsic motivation, and engagement. However, the benefits of autonomy and decision-making differ across cultures.
A new study published by Binghamton University found that even small amounts of alcohol exposure during pregnancy can cause anxiety in offspring, lasting through adolescence and adulthood. The research used low levels of alcohol exposure to reach this conclusion, differing from previous studies that used high levels.
A study published in JAMA Pediatrics found that e-cigarette users who vaped with higher nicotine concentrations were more likely to use combustible cigarettes and experience intense vaping. The research suggests regulatory policies addressing nicotine concentration levels may affect progression of smoking and vaping among adolescents.
A new study by Nutrition Strategies Inc. found that sandwich ingredients, not the bread itself, are the most significant drivers of calories, fat and sodium in US children's diets. By building a better sandwich on either whole grain or enriched grain bread, American children can reduce their intake of these nutrients
A study found that having a parent with an alcohol use disorder increases the risk of teenage dating violence. Researchers identified family dynamics in infancy and middle childhood as critical factors in the development of aggression and dating violence.
A new study by San Diego State University finds that adolescents are sleeping fewer hours per night than older generations, with 40% of teenagers in 2015 sleeping less than 7 hours a night. Young people's increased smartphone use is linked to decreased sleep, with teens who spend more time online being more likely to not get enough sleep.
A study by Kathryn Farr found that school shooters often experience social shunning, bullying, and rejection due to their perceived masculine struggles. Schools can help prevent rampage shootings by addressing adolescent masculinity issues through in-school services, discussion-based forums, and curriculum changes.

A new study by Imperial College London and the World Health Organization found that childhood and adolescent obesity rates increased tenfold over four decades, from less than 1% in 1975 to nearly 6% in girls and 8% in boys in 2016. The number of obese children and adolescents is expected to surpass those who are underweight by 2022. He...
Global childhood obesity rates have increased ten-fold over four decades, with 12-16 million overweight youth in Europe. Early intervention and comprehensive policies are crucial to address this complex disease, which has strong associations with adult mortality and morbidity.
The global prevalence of child and adolescent obesity has increased significantly over the past four decades, from 0.7% to 5.6% for girls and 0.9% to 7.8% for boys. Despite this rise, more children remain moderately or severely underweight than obese globally, highlighting the need to improve food security.
A recent study from the University of Rochester Medical Center found that teenagers who start high school before 8:30 a.m. are at higher risk of depression and anxiety, even with good sleep hygiene. The study suggests that later school start times may be a strong protective factor for teens.
A study tracking over 3600 participants found that maternal factors and depression/anxiety were significant predictors of adolescent sleep problems. Conversely, an active lifestyle was found to decrease future incidence of sleep problems.
