Up to 1 in 5 children suffer from a mental disorder, CDC says

Up to 20 percent of children in the United States suffer from a mental disorder, and the number of kids diagnosed with one has been rising for more than a decade, according to a report released on Thursday by the U.S. Center for Disease Control and Prevention. In the agency's first-ever study of mental disorders among children aged 3 to 17, researchers found childhood mental illnesses affect up to one in five kids and cost $247 billion per year in medical bills, special education and juvenile justice. Children with mental disorders - defined as “serious deviations from expected cognitive, social, and emotional development” - often have trouble learning in school, making friends, and building relationships later in life, the report said. They are more likely to have other chronic health problems, such as asthma and diabetes, and are at risk for developing mental illnesses as adults. “This is a deliberate effort by CDC to show mental health is a health issue. As with any health concern, the more attention we give to it, the better. It's parents becoming aware of the facts and talking to a healthcare provider about how their child is learning, behaving, and playing with other kids,” Dr. Ruth Perou, the lead author of the study, said in an interview. “What's concerning is the number of families affected by these issues. But we can do something about this. Mental health problems are diagnosable, treatable and people can recover and lead full healthy lives,” Perou added. The study cited data collected between 1994 and 2011 that showed the number of kids with mental disorders is growing. The study stopped short of concluding why, but suggested improvements in diagnoses as one possible explanation “Changes in estimated prevalence over time might be associated with an actual change in prevalence, changes in case definition, changes in the public perception of mental disorders, or improvements in diagnosis, which might be associated with changes in policies and access to health care,” the study said. Perou said more research was needed to determine the specific causes of mental disorders, and that greater awareness could lead to an uptick in diagnoses. A host of environmental factors, including chemical exposure and poverty, can also affect a child's mental health, she said. Lead, for example, is known to be “one of the biggest toxins to impact behavior and learning,” Perou said. Poor children are at a higher risk for developing certain conditions, according to the study. The most prevalent mental health diagnosis, as reported by parents, was Attention Deficit/Hyperactivity Disorder (ADHD), which affects 6.8 percent of children. Also common were behavioral conduct problems (3.5 percent), anxiety, which consists mostly of fears and phobias (3 percent), depression (2.1 percent) and autism spectrum disorders (1.1 percent). Many of these disorders occur together, the report said. Boys were found more likely to have most of the listed disorders except for depression and alcohol abuse, which affect more girls. The study also noted that suicide, which can be precipitated by an untreated mental illness, was the second leading cause of death (after accidents) among children 12 to 17 years old. The CDC report was based on multiple other studies that collected data and interviewed children and their guardians about their diagnoses, habits, behaviors and other factors.source : http://www.foxnews.com/health/2013/05/17/up-to-1-in-5-children-suffer-from-mental-disorder-cdc-says/

Vietnam War chemical tied to aggressive prostate cancer risk

Men who were exposed to Agent Orange chemicals used during the Vietnam War are at higher risk for life-threatening prostate cancer than unexposed veterans, researchers have found. What's more, those who served where the herbicide was used were diagnosed with cancer about five years earlier than other men, on average, in the new study. “This is a very, very strong predictor of lethal cancer,” said urologist Dr. Mark Garzotto, who worked on the study at the Portland Veterans Affairs Medical Center in Oregon. “If you're a person who's otherwise healthy and you've been exposed to Agent Orange, that has important implications for whether you should be screened or not screened,” he told Reuters Health. But one researcher not involved in the new study said it's hard to take much away from it, given the imprecise way it measured exposure. Agent Orange - named after the giant orange drums in which the chemicals were stored - was used by the U.S. military to destroy foliage, mainly in southern Vietnam. The herbicide was often contaminated with a type of dioxin, a potently carcinogenic chemical. The Vietnam Red Cross Society has estimated that up to one million Vietnamese suffered disabilities or health problems as a result of Agent Orange, including children born with birth defects years after their parents were exposed. Past research has also suggested that U.S. veterans who served where Agent Orange was used are at an increased risk of lymphoma and certain other cancers, including prostate cancer. For the new study, researchers wanted to see whether exposure was more closely linked to slow-growing prostate cancers or aggressive tumors. They analyzed medical records belonging to 2,720 veterans who were referred to the Portland VA for a prostate biopsy. About one in 13 of those men had been exposed to Agent Orange during the Vietnam War, according to their VA intake interviews. One third of all men in the study were diagnosed with prostate cancer, about half of which were high-grade cancers - the more aggressive and fast-growing type. When the researchers took men's age, race, weight and family history of cancer into account, they found those with Agent Orange exposure were 52 percent more likely than unexposed men to have any form of prostate cancer. Separating out different types of tumors showed the herbicide was not linked to an increased risk of slower-growing, low-grade cancer. But it was tied to a 75 percent higher risk of being diagnosed with aggressive prostate cancer, the study team reported Monday in the journal Cancer. “The increase in the rate of cancers was almost exclusively driven by the potentially lethal cancers,” said Garzotto, also from Oregon Health & Science University. More research is needed to figure out exactly why that is, he said. In the meantime, Garzotto said veterans who were exposed to Agent Orange should discuss that with their doctors. But Dr. Arnold Schecter, from the University of Texas School of Public Health's Environmental and Occupational Health Sciences Program in Dallas, said there's a “big problem” with just asking veterans if they were exposed to Agent Orange or served in an area where it was sprayed. “Of those most heavily exposed in the military as best we know, only a relatively small percentage of them had elevated dioxin from Agent Orange in their blood when tested by (the U.S. Centers for Disease Control and Prevention),” he told Reuters Health. Schecter said that in Vietnam, people who have high levels of that type of dioxin in their blood live in places where the chemical has become integrated into the food supply - or were sprayed directly with Agent Orange. Another researcher who has studied the effects of Agent Orange agreed that not having blood dioxin levels is a drawback, but said the findings are consistent with past research and general thinking about the chemical. “Almost all studies have implicated that men with Agent Orange (exposure) either have higher-grade prostate cancer or a more aggressive clinical course,” said Dr. Gregory Merrick, head of Wheeling Hospital's Schiffler Cancer Center in West Virginia, who also wasn't involved in the new research. But, he added, as long as men are getting into the VA system and getting regular evaluations and treatment for cancer, Agent Orange exposure “is not a death sentence by any means.”source : http://www.foxnews.com/health/2013/05/13/vietnam-war-chemical-tied-to-aggressive-prostate-cancer-risk/
