UTHealth researchers report prevalence of sexting among minority youth
2013-03-07
(Press-News.org) HOUSTON—(March 6, 2013)—Researchers at The University of Texas Health Science Center at Houston (UTHealth) have found that up to 30 percent of minority youths reported sending or receiving "sexts," which are sexually explicit messages sent through technology including photos, videos and text-only messages.
"Although sexting is relatively common among youth and there has been a lot of attention about sexting in the media, there hasn't been much about sexting among ethnic minority youth," said lead investigator Melissa Fleschler Peskin, Ph.D., assistant professor of behavioral science and epidemiology at The University of Texas School of Public Health, part of UTHealth.
The study was published in a recent online issue of "Cyberpsychology, Behavior, and Social Networking." Peskin and colleagues analyzed information collected from more than 1,000 tenth graders from a large, urban school district in southeast Texas who took self-interview surveys on computers.
According to the report, more than 20 percent of students reported sending nude or semi-nude pictures or videos or sexually explicit text messages. More than 30 percent of participants reported receiving a sext. Half of the students who participated in sexting behaviors reported sending and receiving sexually suggestive text-only messages and nude or semi-nude photos. Researchers believe this overlap in sexting behavior has not been previously reported.
Black males and females were more likely than Hispanic males to participate in some sexting behaviors. Hispanic females reported the lowest rates of sexting.
Additionally, almost 10 percent of participants said they had sent a sext to an unintended recipient, and 20 percent reported having a sext shared with them.
"The first step we try to do with any new trend when there is a potential issue or health concern is to understand the extent and prevalence of the issue so we can understand whether a population, in this case one that has not previously been studied, is also engaging in the behavior," Peskin said. "Now that we understand more about the extent of the issue, we can then go to the next step, which is to determine what potential negative, or positive, outcomes are associated with the behavior." Peskin believes more studies are needed to determine if sexting impacts other behaviors and health outcomes among youth.

"We estimate that three percent of all premature deaths can be attributed to the high consumption of processed meat," summarizes Sabine Rohrmann from the Institute of Social and Preventive Medicine at the University of Zurich. Teaming up with research colleagues from ten countries, she has been studying the link between the consumption of processed meat and the risk of mortality as part of a Europe-wide study with around 450,000 participants.
People who eat a lot of processed meat such as sausage products, salami or ham ...

Anyone whose hand or foot has "fallen asleep" has an idea of the numbness and tingling often experienced by people with peripheral nerve damage. The condition also can cause a range of other symptoms, including unrelenting pain, stinging, burning, itching and sensitivity to touch.
Although peripheral neuropathies afflict some 20 million Americans, their underlying causes are not completely understood. Much research has focused on the breakdown of cellular energy factories in nerve cells as a contributing factor.
Now, new research at Washington University School of Medicine ...

RIVERSIDE, Calif. (http://www.ucr.edu) — A University of California, Riverside Bourns College of Engineering professor and a team of researchers published a paper today that shows how they solved an almost century-old problem that could further help downscale the size of electronic devices.
The work, led by Alexander A. Balandin, a professor of electrical engineering at UC Riverside, focused on the low-frequency electronic 1/f noise, also known as pink noise and flicker noise. It is a signal or process with a power spectral density inversely proportional to the frequency. ...

Viruses often spread through the brain in patchwork patterns, infecting some cells but missing others. New research at Washington University School of Medicine in St. Louis helps explain why. The scientists showed that natural immune defenses that resist viral infection are turned on in some brain cells but switched off in others.
"The cells that a pathogen infects can be a major determinant of the seriousness of brain infections," says senior author Michael Diamond, MD, PhD, professor of medicine. "To understand the basis of disease, it is important to understand which ...

The earthquake zones off of certain coasts—like those of Japan and Java—make them especially vulnerable to tsunamis, according to a new study. They can produce a focusing point that creates massive and devastating tsunamis that break the rules for how scientists used to think tsunamis work.
Until now, it was largely believed that the maximum tsunami height onshore could not exceed the depth of the seafloor. But new research shows that when focusing occurs, that scaling relationship breaks down and flooding can be up to 50 percent deeper with waves that do not lose height ...

A research team at the University of Guelph has developed a new line of transgenic "Enviropigs." The new line of pigs is called the Cassie line, and it is known for passing genes on more reliably. The results of this project were published ahead of print in the Journal of Animal Science.
Enviropigs have genetically modified salivary glands, which help them digest phosphorus in feedstuffs and reduce phosphorus pollution in the environment. After developing the initial line of Enviropigs, researchers found that the line had certain genes that could be unstable during reproduction ...

Wednesday, March 6, 2013, Cleveland: Concussions are the leading cause of brain damage in sports, particularly in football. However, researchers at Cleveland Clinic and the University of Rochester have found that football players may suffer long-term brain changes even in the absence of concussion.
In a study of 67 college football players, researchers found that the more hits to the head a player absorbed, the higher the levels of a particular brain protein that's known to leak into the bloodstream after a head injury. Even though none of the football players in the ...

Scientists at A*STAR's Genome Institute of Singapore (GIS) have developed a novel technique to precisely monitor and study the evolution of micro-organisms such as viruses and bacteria. This is an extremely important capability as it allows scientists to investigate if new drugs designed to kill them are working, and catch the development of resistance early on.
Micro-organisms and cancer cells evolve more quickly than normal human cells as their rapid life-cycles enable faster selection of advantageous mutations. Previously, scientists have had to wait for the selection ...

Flu viruses are a major cause of death and sickness around the world, and antiviral drugs currently do not protect the most seriously ill patients. A study published March 7th by Cell Press in the journal Cell reveals that a compound derived from fats found in fish oils prevents death in influenza-virus-infected mice, even at advanced stages of disease. The study offers a promising strategy for the treatment of patients with severe influenza virus infections.
"Given the potential for future lethal pandemics, effective drugs are needed for the treatment of severe influenza, ...

When animals like dogs or rats sniff one another, there might be more going on than you'd think. Research reported in Current Biology, a Cell Press publication, on March 7th finds in rats that those sniffing behaviors communicate information about an individual's social status. In those encounters, more dominant rats act as primary sniffers, while subordinate sniffees actually slow their breath.
"We know that rats and other animals can communicate through vocalizations, physical contact, odors, and also visual displays," says Daniel Wesson of Case Western Reserve University. ...
