Teen drivers and passengers are more likely to use seat belts in states with "click it or ticket" laws, according to a new study in the American Journal of Public Health. These laws, also known as primary enforcement laws, allow police to stop and ticket drivers for not wearing a seat belt. Under a secondary law, police can only ticket drivers not buckled up if they are stopped for some other reason, such as speeding.
The study found that in states with secondary laws teens were 12 percent less likely to wear a seat belt when driving and 15 percent less likely to do so as a passenger than teens in states with primary laws. Read more on public health law.
A new study by researchers at the University of British Columbia found that a survey of 17,000 Canadian students in grades 8 to 12 showed that 25 to 30 percent admitted to cyberbullying, while only twelve percent said they had participated in schoolyard bullying. The researchers say that indicates that current prevention programs may not be sufficient to protect kids from online bullying. Read more on violence prevention.
Researchers analyzing data from a survey of Vietnam War veterans have found that those with more killing experiences were twice as likely to have suicidal thoughts as those with fewer or no experiences of killing.
The researchers, who published their findings in the journal Depression and Anxiety, say the association between killing and suicidal thoughts remained even after adjusting for variables such as post-traumatic stress disorder, depression, substance use disorders and combat exposure.
"We want clinicians and suicide prevention coordinators to be aware that in analyzing a veteran's risk of suicide, killing in combat is an additional factor that they may or may not be aware of,” says Shira Maguen, PhD, the study’s lead researcher. Read more on military health.
