The religion of suicide victims and their parents aren't tracked officially, but over 50% of the population of Utah identify as Mormon.

I am perfectly willing to accept that more rural areas tend to have higher suicide rates, and that is not necessarily going to be correlated with religion, but at the same time, 1/3 of the population lives in the SLC metro area, which should be a moderating influence on the state's suicide rate if this is the primary cause.

The only other statistic I know of regarding Utah that is an outlier over the US in general is the percentage of individuals who identify as Mormon. As such, a hypothesis that the higher adolescent suicide rate has something to do with religion is perfectly valid, although still only a hypothesis.
