| NIJMEGEN, Netherlands (UPI) -- A study of 428 families in the Netherlands found the more teenagers were allowed to drink at home, the more they drank outside of home as well.
Lead researcher Dr. Haske van der Vorst of Radboud University Nijmegen says the study looked at families with two children between the ages of 13 and 15.
"The idea is generally based on common sense," van der Vorst says in a statement. "For example, the thinking is that if parents show good behavior -- here, modest drinking -- then the child will copy it. Another assumption is that parents can control their child's drinking by drinking with the child."
The researchers found that, in general, the more teens drank at home, the more they tended to drink elsewhere; the reverse was also true, with out-of-home drinking leading to more drinking at home.
Teens who drank more often, whether in or out of the home, tended to score higher two years later on a measure of problem drinking.
The study is published in the Journal of Studies on Alcohol and Drugs.

| PORTLAND, Ore. (UPI) -- A U.S. researcher says attention-deficit hyperactivity disorder may be linked to the neurotoxin lead -- still found in some toys, jewelry and water.
Joel Nigg of Oregon Health & Science University in Portland points to lead as an ideal candidate to trigger the developmental disorder called ADHD.
In his article, published in Current Directions in Psychological Science, Nigg offers a causal model in which lead attaches to sites in the brain's striatum and frontal cortex, and acts on the genes in these regions -- causing them to turn on or remain inactive. This disruption in brain activity alters cognitive control, and in turn results in hyperactivity and lack of vigilance.
Two recent studies, Nigg says, provide strong evidence of the link between ADHD and lead. One found children who had been diagnosed with ADHD had slightly higher levels of lead in their blood than healthy controls.
The second study shows a link between blood lead and both parent and teacher ratings of ADHD symptoms, including both hyperactivity and attention problems. In both studies, the connection was independent of IQ, family income, race or maternal smoking during pregnancy.
