Study: Health of US children mixed

(CNN) - A new report called, "America's Children: Key National Indicators of Well-Being 2011," took a look at kids across the nation.

The study said there is a drop in teen birth rates, down to about 20 births in every 1,000 girls ages 15 to 17.

The percentage of premature babies born to all mothers also dropped slightly, to just over 12 percent.

Some of the negative news: The report found an increase in drug use among eighth-graders, and more children were likely to live in poverty.

The report was compiled by the Federal Interagency Forum on Child and Family Statistics.
