"While we can't shelter all our kids from everything, the important thing is teaching them how to react and how to interpret the messages they are seeing," Comkornruecha said.
Another paper in the same journal issue found that too few doctors counsel adolescents about the dangers of drinking.
That 2010 study of 10th graders -- led by Ralph Hingson from the Eunice Kennedy Shriver National Institute of Child Health and Human Development -- found that 36 percent drink, 28 percent binge-drink and 23 percent were drunk in the past month.
Although 82 percent had seen a doctor and 54 percent were asked about drinking, only 17 percent were counseled to reduce or stop drinking, the researchers found.
The researchers concluded that "efforts are warranted to increase the proportion of physicians who follow professional guidelines to screen and counsel adolescents about unhealthy alcohol use and other behaviors that pose health risks."
