Opioid gene variant in adolescents reduces reward, may increase later substance abuse risk

Adolescents with a particular variant of an opioid receptor gene have less response in a part of prefrontal cortex that evaluates rewards, compared to those with the other version of the gene, say researchers at Georgetown University Medical Center (GUMC). For the study, presented Monday at Neuroscience 2018, the annual meeting of the Society for Neuroscience (abstract #7517), the investigators […]

Both quantity and quality of sleep affect cardiovascular risk factors in adolescents

A study from a research team led by a MassGeneral Hospital for Children (MGHfC) physician finds that both the quantity and quality of sleep—the amount of time spent sleeping and the percentage of sleep that is undisturbed—in young adolescents have significant effects on aspects of cardiovascular health such as blood pressure, cholesterol levels and abdominal fat deposition. Their report has […]

Factors associated with sexual coercion among adolescents in rural communities

A new study examining factors associated with sexual coercion among 10th graders in a rural Midwestern, low-to-middle income high school found that sexual coercion was reported by 18 percent (13 percent of males and 23 percent females).

At-risk adolescents are less likely to express depression on social media as they age

Findings from a new study reveal at-risk adolescents are less likely to post about depressive symptoms on social media as they age. The research suggests that adolescents with a diagnosis of depression may feel less stigmatized describing depressed mood on social media than previously hypothesized. The research will be presented during the Pediatric Academic Societies (PAS) 2018 Meeting in Toronto. […]

Eyes of adolescents could reveal risk of cardiovascular disease

New research has found that poorer well-being or ‘health-related quality of life’ (HRQoL) in adolescence could be an indicator of future cardiovascular disease risk. Researchers at The Westmead Institute for Medical Research found that adolescents with poorer scores in the social and mental well-being domains of HRQoL have structural changes in their retinal blood vessels that could be associated with […]
