A study from the University of Colorado School of Medicine found that physicians' delivery and communication practices must improve to boost HPV vaccine completion rates. Pediatricians who strongly recommend the vaccine have higher acceptance rates, and optimizing HPV delivery through standing orders and alert systems can also help.
New research shows that e-cigarette ads are highly effective in targeting adolescents, with many failing to critically evaluate the information presented. The study found that youths are drawn to the 'cool factor' and emotional appeal of the ads, which can lead to an increased desire to try e-cigarettes.
A study of 804 adolescents found that adolescent girls with an evening chronotype who prefers going to bed and waking up later tend to have bigger waistlines and greater fat mass. This association holds true even after adjusting for other lifestyle factors. The study suggests that addressing irregular sleep patterns may be important in...

The study suggests that setting boundaries and improving media literacy may help mitigate these risks.
A study from Finland found that the proportion of adolescents diagnosed with depression in specialized services has been increasing, largely due to an earlier age of diagnosis. The increase in service use poses a burden on specialized mental health services as they provide evidence-based treatment for a growing patient population.

A new study from Finland found that adolescents with higher levels of physical activity performed better in school during a two-year follow-up period. However, the results also showed that increasing physical activity did not necessarily result in improved academic performance, and may even lead to lower grades for some participants.
Research shows that puberty affects brain networks differently in males and females, with boys experiencing increased connectivity and girls experiencing decreased connectivity. This study found significant changes in mood-related brain areas during puberty, which may be linked to the higher incidence of depression in girls.

Research from the University of Georgia found that adolescents who were not in romantic relationships during middle and high school had good social skills and low depression. Non-dating teens fared equally well or even better than their peers who dated, according to a new study.
A new study published in Journal of School Health found that non-daters have good social skills and low depression. Adolescents who were not in a romantic relationship fared better or equal to peers who dated.
Research suggests that overweight adolescents experience a biological response driving reduced appetite when stressed, eating about 35% fewer calories in the two hours following. This study challenges the common assumption that stress leads to overeating and highlights the importance of understanding individual responses to stress.
A study using a blood marker of inflammation found an association between late adolescence inflammation and death among Swedish men up to age 57. The results suggest that chronic inflammation in young adulthood may increase the risk of mortality decades later.

Tuberculosis cases among children and adolescents in the USA have almost halved within a decade, yet stark differences exist in incidence rates between different groups. Disparities persist despite successful overall burden reduction, with higher rates found in indigenous populations, US islands, and children born outside the USA.
A review of adolescent brains across species reveals that impulsiveness is a biological adaptation crucial for brain maturation. The human brain undergoes significant changes during adolescence, including pruning of neural connections and strengthening of white matter tracts, which enables optimal brain function in the adult stage.
A University of Michigan study found that children with vitamin D deficiency during elementary school were nearly twice as likely to develop externalizing behavior problems as those with higher levels. Low levels of the protein transporting vitamin D were also linked to self-reported aggressive behavior and anxious/depressed symptoms.

The study suggests that e-cigarette use may be a gateway to marijuana use, particularly among vulnerable populations.
A new study found that young adults in Asia have the shortest sleep duration, averaging 6 hours and 30 minutes per night. The researchers suggest that cultural factors, such as high work demands and limited leisure time, contribute to this trend.
A new study found that nearly one in eight female adolescents between ages 14 and 19 experienced reproductive coercion, a form of abuse where a woman is pressured to become pregnant against her wishes. The study also highlights the need for clinicians to understand how to spot relationship abuse in younger patients.

The research suggests that promoting physical activity in childhood may have long-term benefits for respiratory health, particularly in adolescent girls.
A new study suggests that measuring both birthweight and length provides a more accurate indication of fetal growth and future cardiovascular risk. A low ponderal index or body mass index at birth is associated with an increased risk of heart problems later in life.

Adolescents who skip breakfast tend to have higher waist circumference and body mass index, indicating an increased risk of weight gain. The study suggests that skipping breakfast can contribute to unhealthy habits and behaviors, potentially making adolescents more vulnerable to obesity.
Research by Irene Perini at Linköping University found that adolescent girls who self-injure believe they receive more negative feedback than actuality, leading to lower liking for themselves and others. This bias affects their brain's salience network, particularly associated with emotions and reflection.
A recent study found that nearly 11% of high school seniors reported misusing prescription drugs in the past year, with 44% relying on multiple sources. This increases the risk of substance use disorders and other issues.
Research from Duke Health suggests that new e-cigarette laws could have unintended consequences on existing users, leading them to smoke more traditional tobacco cigarettes. The study found that limiting flavors or customizability of e-cigarettes might cause some users to increase their use of traditional cigarettes.
A new study by University of Montreal scientists reveals that social media use and television viewing are associated with increased adolescent depressive symptoms. The study found that teens who spent more time on social media and in front of the TV experienced more severe depression over a four-year period.
A new study found that videogames, as part of an emotional intelligence training program, can enhance teenagers' evaluation and expression of emotions. The game, EmotivaMente, was designed to promote emotional intelligence among adolescents and showed promising results in this area.
A new study reveals that school suspensions are not only ineffective but also increase subsequent offending behaviors, including assault, stealing, and selling drugs. The research found that exclusionary discipline amplifies deviant behavior among youth, leading to higher crime rates in schools, neighborhoods, and communities.
Researchers found that intranasal insulin delivery improves performance on memory tasks and increases brain connectivity in adolescents with high BMI. The study suggests that obesity-related cognitive impairment can be reversed by intranasal insulin.
A longitudinal study found that derisive parenting, characterized by belittling expressions, fosters dysregulated anger in adolescent children, increasing their risk for bullying and victimization. This type of parenting, often overlooked, is a unique form of parenting that contributes to peer difficulties.
