Anxiety More Important Than Looks in Teen Eating Disorders
In teens with eating disorders, anxiety plays a bigger role than dissatisfaction with appearance, says a study by Finnish researchers.
They conducted two surveys, a year apart, of 372 students, ages 15 to 17, and found that 13 percent reported eating disorders in either the first or second survey and 5 percent reported eating disorders in both surveys, United Press International reported.
The researchers also found that students who reported suffering from anxiety earlier in adolescence were 20 times more likely to report ongoing eating disorders. Teens who said they were dissatisfied with their appearance only had recurring eating disorders if they also reported anxiety earlier in adolescence.
Teens with eating disorders were more likely than those without eating disorders (70 percent vs. 40 percent) to report one or more health problems such as insomnia, fatigue, headache, abdominal pain or dizziness, UPI reported.
The study was published in the Journal of Advanced Nursing.
Dental Fillings With Mercury Pose Threat to Children, Fetuses: FDA
Dental fillings that contain mercury may be harmful to children and fetuses, the U.S. Food and Drug Administration said in a warning posted on its Web site Wednesday.
The agency agreed to post the warning as part of a lawsuit settlement reached with several consumer advocates. The FDA also agreed that by July 2009, it would issue a more specific rule for fillings that contain mercury, FOXNews reported.
"Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses," says the warning on the FDA Web site.
"Pregnant women and persons who may have a health condition that makes them more sensitive to mercury exposure, including individuals with existing high levels of mercury bioburden, should not avoid seeking dental care but should discuss options with their health practitioner," the FDA advises.
Crib Mattresses Recalled Due to Entrapment Hazard
About 20,000 Simmons Kids Crib mattresses are being recalled because they may pose an entrapment hazard to infants. Some of the mattresses can measure smaller than the 27 1/4-inch minimum width requirement for cribs, leaving a gap between the mattress and side rails, the U.S. Consumer Product Safety Commission said.
There's been one report involving a six-month-old baby becoming wedged between the mattress and the crib's frame. The baby was unharmed.
The recall covers open coil mattresses made between July 1, 2006, and March 23, 2008, with the following model names: Pottery Barn Kids by Simmons Kids Lullaby; Simmons Kids Slumber Time Evening Star Luxury Firm; Simmons Kids Baby Mattress Series 400; Simmons Kids Baby Mattress 234 Coil Count.
They were sold at Pottery Barn Kids and nursery furniture stores across the United States for between $100 and $150.
