Research finds effects go beyond increase in aggression
COLUMBUS, Ohio – Playing violent video games not only increases aggression, it also leads to less self-control and more cheating, a new study finds.
Researchers found that teens who played violent video games ate more chocolate and were more likely to steal raffle tickets in a lab experiment than were teens who played nonviolent games. (more…)
Specific area of the brain linked to anxiety disorders in youth
Anxiety disorders are common in children and adolescents, affecting up to 25 percent of the youth population. Anxiety causes distress and functional impairment and, if left untreated, can result in bad grades, problems at home and increased rates of psychiatric disorders in adulthood.
These risks constitute a significant public health burden, and they underscore the importance of continued efforts to understand the cause and course of the disorder. (more…)
In a new study, addiction researchers found that attentive parenting can overcome a genetic predisposition to alcohol use disorder among teens. Although further research is needed, says lead author Robert Miranda Jr., parents can have an impact if they “closely monitor their child’s behavior and peer group.”
In 2010 a team led by Robert Miranda Jr., associate professor (research) of psychiatry and human behavior in the Warren Alpert Medical School of Brown University, found that teens with a single difference in their genes were more predisposed to alcohol use disorder. In a new study in Alcoholism: Clinical and Experimental Research he found that the risk was largely overcome in teens whose parents are attentive to their behavior and peer group. Miranda, a researcher at Brown’s Center for Alcohol and Addiction Studies, answered questions from science writer David Orenstein about the new study.
What did we know about genetic risk associated with A118G and teenage alcohol use going into this study?
In 2010, we reported in Alcoholism: Clinical and Experimental Research the first evidence that the A118G SNP of the OPRM1 gene is associated with a greater number of alcohol-related problems as well as the development of an alcohol use disorder (AUD) among adolescents. Specifically, adolescents who met criteria for an AUD diagnosis had a higher prevalence of the G allele (51.9 percent) than non-AUD youth(16.3 percent), and the G allele accounted for 9 percent of the variance in alcohol-related problems experienced by youth in the past three months, with a moderate effect size. Although these findings are consistent with some adult studies in terms of the nature and magnitude of this association, other adult studies did not find this relationship. (more…)
Adolescents who smoke cigarettes or use alcohol or marijuana may be at greater risk for subsequent abuse of prescription opioids as young adults, according to a new study by Yale School of Medicine.
The researchers believe their findings are the first to demonstrate that early alcohol, cigarette, and marijuana use are all associated, to varying degrees, with a two- to-three times greater likelihood of subsequent abuse of prescription opioids. The study appears online in the Journal of Adolescent Health. (more…)
EAST LANSING, Mich. — The peak risk for misusing prescription pain relievers occurs in mid-adolescence, specifically about 16 years old and earlier than many experts thought, according to a new study by Michigan State University researchers.
The results, based on recent nationwide surveys of nearly 120,000 U.S. adolescents, suggest prevention programs may need to be introduced earlier, in childhood and early adolescence, said James C. Anthony of MSU’s Department of Epidemiology and Biostatistics. (more…)
ANN ARBOR, Mich.— Among the more important findings from this year’s Monitoring the Future survey of U.S. secondary school students are the following:
- Marijuana use among teens rose in 2011 for the fourth straight year—a sharp contrast to the considerable decline that had occurred in the preceding decade. Daily marijuana use is now at a 30-year peak level among high school seniors.
- “Synthetic marijuana,” which until earlier this year was legally sold and goes by such names as “K2” and “spice,” was added to the study’s coverage in 2011; one in every nine high school seniors (11.4%) reported using that drug in the prior 12 months.
- Alcohol use—and, importantly, occasions of heavy drinking—continued a long-term gradual decline among teens, reaching historically low levels in 2011.
- Energy drinks are being consumed by about one third of teens, with use highest among younger teens. (more…)
*MU study finds disordered eating combined with heavy drinking is common among college students*
COLUMBIA, Mo. – It is well known that eating disorders are common among teens and college students. Heavy alcohol consumption is another well-known unhealthy habit of this age group. A new study from the University of Missouri shows that when college students combine these two unhealthy habits, their long-term health may be affected. “Drunkorexia” is a new term coined by the media to describe the combination of disordered eating and heavy alcohol consumption.
Victoria Osborne, assistant professor of social work and public health, examined the relationship between alcohol misuse and disordered eating, including calorie restriction and purging. Researchers found that 16 percent of those surveyed reported restricting calories to “save them” for drinking. Of the respondents, about three times as many women reported engaging in the behavior than men. Motivations for “drunkorexia” include preventing weight gain, getting intoxicated faster and saving money that would be spent on food to buy alcohol. (more…)
