Fewer Utah teens are getting pregnant.

The State Department of Health reports this week, the number of girls -- age 15 to 19 -- getting pregnant in the state has fallen 28 percent over the past seven years.

Health officials say the local trend follows what's happening across the country. 

They say the state is providing more sex education materials than in the past -- but, the admit they aren't sure what is causing the teen pregnancy decline in Utah.
