The effects of an annual music festival in Grand Junction, Colo., may appear months after the last act plays _ nine months, to be precise.

A health official says her agency sees far more pregnant women in the weeks after Country Jam, which was held last month and featured Tim McGraw, Clay Walker and Sugarland.

Nurse-Family Partnership supervisor Wanda Scott says her agency normally sees 25 to 30 pregnant women a month but the number jumps to almost 80 about five weeks after the festival. She gave her findings to Mesa County commissioners Monday.

Scott’s program helps first-time mothers with low incomes. The average age of clients is 19.
