SALT LAKE CITY (AP) — Researchers studying a spike in teen suicides in Utah found that 18 of the 150 youngsters who took their own lives in a five-year period had recently lost privileges to use their electronic devices such as phones, tablets and gaming systems, according to a U.S. Centers for Disease Control and Prevention report made public Thursday.

The report was released after the agency earlier this month issued findings showing an increase in suicide rates among teens across the U.S. over the 2010-2015 period after they had declined for nearly two decades occurred at the same time social media use surged.

The reports stop short of blaming electronics and social media for the rise in suicides, but say the findings beg for more research on the topic. Among the questions: How dependent are teens today on social support networks accessed through electronic devices?

Utah requested the federal investigation to back up its research after the rate of suicides among youth 10-17 more than doubled from 2011-2015.
