A Mayo Clinic study of teen smoking rates in the Yukon Kuskokwim delta region found young people there use tobacco at high rates. Nearly 30 percent of 11 to 14 year olds and 63 percent of high school students use tobacco, compared to less than 20 percent of teens nationally. Dr. Christi Patten is the lead author of the YK Delta study. She says focus groups with kids in the region helped them design the intervention program for the youth, but the results were not good.
