(Press-News.org) PITTSBURGH, June 22 – Young people who identify themselves as gay, lesbian or bisexual, experience same-sex attractions or engage in same-sex sexual behaviors are more likely to experience sexual abuse, parental physical abuse and bullying from peers than other youth, according to a University of Pittsburgh Graduate School of Public Health study.
In addition, these adolescents – identified as "sexual minority youth" in the study – are more likely to miss school due to fear. The American Public Health Association recently published the findings online; the study will appear in the August issue of the American Journal of Public Health.
"The higher rates of abuse experienced by sexual minority youths are clearly one of the driving mechanisms underlying higher rates of mental health problems, substance use, risky sexual behavior and HIV by sexual minority adolescents and adults," said Mark S. Friedman, Ph.D., assistant professor of behavioral and community health sciences. "However, I cannot stress enough that these youth experience sexual and physical abuse and bullying because they identify as gay, lesbian or bisexual or experience same-sex attraction; abuse does not 'cause' sexual orientation or identification."
Friedman and his co-authors conducted a meta-analysis of 37 studies in 18 geographic areas that compared the likelihood of self-reported childhood sexual abuse, physical abuse perpetrated by a parent or guardian or peer victimization between high-school aged sexual minority and non-minority youth. The meta-analysis only included school-based studies conducted in North America of randomly sampled youth.
Many studies have suggested that young people who identify as gay, lesbian or bisexual, experience same-sex attractions or engage in same-sex sexual activity are more likely to experience sexual or physical abuse or bullying from peers than other youth. However, these studies vary in effect sizes, sampling and recruitment strategies, measurements and other issues. Therefore, Friedman and his team chose to conduct a meta-analysis, a complex statistical procedure that combines the results of multiple studies.
According to the meta-analysis, sexual minority youth are:
Nearly three times more likely to report childhood sexual abuse, compared with other adolescents
1.3 times more likely to report parental physical abuse than other adolescents
1.7 times more likely to report being threatened or injured with a weapon, or otherwise assaulted as compared to their peers
Nearly three times more likely to report missing school because they were afraid
Studies revealed a high rate of prior sexual abuse among bisexual female (40 percent), lesbian (32 percent), bisexual male (24 percent), gay male (21 percent) and heterosexual female (17 percent) youth, compared to 5 percent of heterosexual male adolescents.
According to the report, children and adolescents who experience sexual and parental physical abuse are more likely to suffer from psychological, substance abuse, behavioral and criminal problems. Those who are abused and assaulted by peers are more likely to experience poor school performance, delinquency, social isolation, psychological and substance abuse problems and other issues, the study said.
The U.S. Centers for Disease Control and Prevention recently released a study that found adolescents who identify as gay, lesbian or bisexual are more likely than their heterosexual peers to take unhealthy risks.
"We need to continue our research to examine how the abuse and mistreatment these young people endure is connected to the risky behaviors they might engage in and, of great importance, programs to prevent such abuse are urgently needed," Friedman said.

An international team of geoscientists has discovered an unusual geological formation that helps explain how an undersea earthquake off the coast of Sumatra in December 2004 spawned the deadliest tsunami in recorded history.
Instead of the usual weak, loose sediments typically found above the type of geologic fault that caused the earthquake, the team found a thick plateau of hard, compacted sediments. Once the fault snapped, the rupture was able to spread from tens of kilometers below the seafloor to just a few kilometers below the seafloor, much farther than weak sediments ...

A team of scientists studying the galaxy cluster Abell 2744, nicknamed Pandora's Cluster, have pieced together the cluster's complex and violent history using telescopes in space and on the ground, including the Hubble Space Telescope, the European Southern Observatory's Very Large Telescope, the Japanese Subaru telescope, and NASA's Chandra X-ray Observatory.
The giant galaxy cluster appears to be the result of a simultaneous pile-up of at least four separate, smaller galaxy clusters. The crash took place over a span of 350 million years.

Tropical Depression Haima, formerly known as 06W continues moving toward Hong Kong and NASA infrared satellite imagery shows strong rain-making thunderstorms in the southern quadrant of the storm. Rainfall is something that a rain-weary China doesn't need, so preparations are being made now.
Heavy rainfall is expected as Haima approaches in southern Taiwan, and also in southern areas of China's Fujian and Guangdong provinces, and Hainan Island. That heavy rainfall was spotted on an infrared image captured by NASA's Atmospheric Infrared Sounder (AIRS) instrument on June ...

MADISON, WI, JUNE 22, 2011 -- Vinyl chloride is a cancer-causing compound formed from solvents in groundwater systems under anaerobic conditions. These solvents are used in many industrial applications around the world and often belong to the most encountered groundwater pollutants in industrialized countries. Groundwater is a major drinking water resource, and it is vital to determine if vinyl chloride can be further degraded into harmless compounds.

ANN ARBOR, Mich. — Scientists at the University of Michigan Health System have for the first time demonstrated how memory circuits in the brain refine themselves in a living organism through two distinct types of competition between cells.
Their results, published today in Neuron, mark a step forward in the search for the causes of neurological disorders associated with abnormal brain circuits, such as Alzheimer's disease, autism and schizophrenia.
"Much of our understanding of the brain's wiring has come from studying our sensory and motor systems, but far less is ...
