Two Hours At TV Or Computer Screen Linked To Psychological Problems In Kids

A child who spends at least two hours a day in front of a TV screen or computer monitor has a significantly higher risk of developing psychological problems, no matter how much physical activity they do, researchers from the University of Bristol's Centre for Exercise, Nutrition and Health Sciences, England reported in an article published in the American Journal of Pediatrics. The more physically active children who were in front of a screen for at least two hours a day appeared to do better than their sedentary peers in emotional and peer problems, but fared worse in behavioral areas, including hyperactivity.

This latest study, called The PEACH project, assessed over 1,000 kids aged ten and eleven years. The investigators gathered data on how long they spent in front of a computer monitor and/or TV screen, as well as their mental health. The children's levels of physical activity were measured and recorded using an activity monitor.

The researchers found that those children who spend at least two hours watching TV and/or using their computer for non-homework use (recreational use) had higher psychological difficulty scores compared to their peers who spent less time in front of screens. The investigators add that the difficulty scores persisted, irrespective of how physically active the children were.

In other words, it appears that regular prolonged exposure to monitors/screens increases the risk of psychological problems, and exercise does not seem to get rid of the problem.

The authors believe that limiting a child's exposure to TV/Computer screens could play an important role in protecting their current and future mental health and well-being.

A Teacher's Suicide: Lessons Learned

Suicide is often seen as the tip of the iceberg. When Mr Ruelas', a Los Angelos teacher, died by suicide last week, it is acknowledged that the motives are far from clear. However some have associated Mr. Ruelas' love of teaching, his despair about the recent release of teacher performance ratings and his shame at being listed as a "less than effective" teacher compelled him to take a fatal jump. I also have the experience losing someone I love to suicide and searching for answers that can bind my anguish. My mother killed herself when I was four years old and as a child psychiatrist, mother, daughter I spent 18 years asking the impenetrable question of "Why?"

The lessons learned for those of us who lose someone to suicide is that it is usually a complex set of events, biological, cultural, conscious, unconscious motives. In ninety percent of suicides there is an underlying mental illness that exacerbates how someone responds to an immediate crisis whether it is a loss of a job, a divorce, the vicissitudes in life that can leave us bereft. In "psychological autopsies" when researchers interview friends and family, someone often has suffered from depression or bipolar disorder.

When someone is depressed and suicidal they can often have lethal misperceptions. Their desperate misery can be fueled by the faulty logic that their problem is permanent and that ending their life is the only solution. If I had climbed next to Mr. Ruelas on the remote forest bridge, the kind of metaphorical outreach that I do with my patients in my office, I would have counseled him in the words of Galway Kinell in his poem to a suicidal friend, "Wait, Wait for now, the need for new love is faithfulness to the old." I would have asked him to look at the evidence that a bad report card can permanently derail a career or can he recognize that this is the "faulty logic" of depression. When someone is suicidal they can see themselves as a perceived burden and that they will not be missed.

The aftermath of Mr. Ruelas' death is a stark reminder that none of us are expendable. As an extension of Mr. Ruelas' love for his students, I want each of them to get the message that depression is a treatable illness. We have life sustaining support to help those in their darkest hours find another way.

Mental Health Courts Appear to Shorten Jail Time, Reduce Re-Arrest for Those With Psychiatric Illness

Special mental health courts appear to be associated with lower post-treatment arrest rates and reduced number of days of incarceration for individuals with serious psychiatric illnesses, according to a report posted online October 4 that will appear in the February 2011 print issue of Archives of General Psychiatry.

"Mental health courts are an increasingly popular post-booking jail diversion program," the authors write as background information in the article. "Mental health courts have the laudable goal of moving persons with serious mental illness out of the criminal justice system and into community treatment without sacrificing public safety." These courts have expanded from one or two in 1997 to approximately 250 today. In general, eligible clients follow specific procedures for enrollment into the court, such as having a hearing before a mental health court judge, entering a guilty plea and agreeing to the terms of the court. Treatment is usually a condition of enrollment, and courts reserve the right to sanction defendants who violate the terms.

Specifically, in the 18 months following enrollment in the mental health court, participants were significantly less likely than those treated in the usual manner to be arrested again (49 percent vs. 58 percent). Over the same period, mental health court participants had a decline of 0.8 arrests per year (from 2.1 to 1.3), compared with a decline of 0.6 in the usual treatment group (from 2.6 to 2.0).

Social Rejection Literally Affects the Heart

We all know that the phrase heartbroken is reflective of a social rejection. New research suggests the phrase may also have some physiological truth as researchers determine social rejection does affect the heart.

Dutch researchers have determined social rejection isn’t just emotionally upsetting; it also makes your heart rate drop for a moment.

The report is published in Psychological Science, a journal of the Association for Psychological Science.

Research has shown that the brain processes physical and social pain in some of the same regions. A team of Dutch researchers wanted to find out how social pain affects you physically.

For the study, volunteers were asked to send the researchers a photograph of themselves. They were told that for a study on first impressions, students at another university would look at the photo to decide whether they liked the volunteer.

This was just a cover story for the real experiment.

A few weeks later, each volunteer came to the laboratory, had wires placed on their chest for an electrocardiogram, and looked at a series of unfamiliar faces—actual students from another university.

For each face, the volunteer was asked to guess whether that student liked them. Then they were told whether the person actually “liked” them or not—although this was merely a computer-generated response.

Each participant’s heart rate fell in anticipation before they found out the person’s supposed opinion of them.

Heart rate was also affected after they were told the other person’s opinion—if they were told the other student didn’t like them, the heart dropped further, and was slower to get back up to the usual rate. The heart rate slowed more in people who expected that the other person would like them.

The results suggest that the autonomic nervous system, which controls such functions as digestion and circulation, gets involved when you’re socially rejected.

“Unexpected social rejection could literally feel ‘heartbreaking,’ as reflected by a transient slowing of heart rate,” the researchers write.

Men Respond to Stress by Shutting Down

A new study finds that stressed men have diminished activity in brain regions responsible for understanding others’ feelings.

In the investigation, researchers had men look at angry faces. The results suggest the silent and stoic response to stress might be a “guy thing” after all.

“These are the first findings to indicate that sex differences in the effects of stress on social behavior extend to one of the most basic social transactions — processing someone else’s facial expression,” said Mara Mather, director of the Emotion and Cognition Lab at USC.

In an article appearing in the journal NeuroReport, Mather and her coauthors present a series of tests indicating that, under acute stress, men had less brain response to facial expressions, in particular, fear and anger.

Men under acute stress showed decreased activity not only in the fusiform face area but also decreased coordination among parts of the brain that help us interpret what emotions these faces are conveying.

In a marked sex difference, women under stress showed the opposite — women under stress had increased activity in the fusiform face area and increased coordination among the regions of the brain used in interpreting facial emotions compared to the control group.

“Under stress, men tend to withdraw socially while women seek emotional support,” Mather said.

Violent Crime Less Frequent in Neighborhoods with Businesses

Neighborhoods that combine residential and business developments have lower levels of some types of violent crime, suggests a new study.

The findings were equally true in impoverished areas as they were in more affluent neighborhoods, possibly offering city planners and politicians a new option in improving crime-afflicted areas, according to the researchers.

“A residential neighborhood needs more than the addition of one or two businesses to see any positive impact on violent crime,” said Christopher Browning, professor of sociology at Ohio State University and lead author of the study.

“There needs to be a sufficient density of businesses and residences throughout the community to really see the benefits.”

The findings are significant as more cities across the country move toward mixed developments as a way to bolster downtowns and run-down neighborhoods, said Browning.

The study appears in the current issue of the Journal of Research in Crime and Delinquency and was supported by a grant from the National Science Foundation.

Physically Fit Kids Have Bigger Hippocampus

Children who are physically active actually boost their own brain development, according to a study by the University of Illinois.

The researchers observed 49 participants, aged nine to ten, and found that physically fit children tend to have a bigger hippocampus and also perform better on memory tests than kids who are less fit.

For the study, magnetic resonance imaging (MRI) was used to measure the relative size of specific structures in the brains of the child participants.

“This is the first study I know of that has used MRI measures to look at differences in brain between kids who are fit and kids who aren’t fit. Beyond that, it relates those measures of brain structure to cognition,” said University of Illinois psychology professor Art Kramer, who led the study with Laura Chaddok, doctoral student.

The study’s main focus was the hippocampus, a structure set deep in the brain and known to play a major role in memory and learning. Previous studies in older adults and animals have shown that exercise can enlarge the hippocampus. A bigger hippocampus is linked to stronger spatial reasoning and other cognitive tasks.

This study appears in the journal Brain Research.
