Up to 30 percent of teenage girls in some parts of the United States say they have intentionally injured themselves without aiming to commit suicide, researchers have found. About one in four adolescent girls deliberately harmed herself in the previous year, often by cutting or burning, compared to about one in 10 boys. The overall prevalence of self-harm was almost 18 percent. “These numbers are very high for both genders — that surprised me,” said Martin A. Monto, a sociologist at the University of Portland and lead author of the new research. (Baumgaertner, 7/2)

If you are a parent worrying through pregnancy, or maybe trying to make sense of your child’s neurodevelopmental problems, you aren’t always glad to see another story about a new study looking at possible environmental risk factors. From pesticides in the food to phthalates in the plastics to pollutant particles in the air, so many different exposures have been linked to problems in the developing fetal brain that parents can sometimes feel both bewildered and, inevitably, at fault for failing or having failed to take all possible precautions.

More and more children in the U.S. are taking alternative dietary supplements that have scant proven benefits and could pose health risks. According to a recent analysis, the rate of children taking alternative or herbal supplements nearly doubled, to 6.3% from 3.7%, between 2003 and 2014. The increase was fueled by melatonin, a hormone used to aid sleep, and omega-3 fatty acids, or fish-oil supplements, which often are given to children with attention-deficit/hyperactivity disorder and autism despite little evidence that they help.
