Suicides and Attendance at Church

The following paragraph comes from the Washington Times.
Psychiatric researchers at the University of Manitoba have established a link, they say, "between a person´s attendance at a religious worship service" and the desire to commit suicide.
No, this doesn't quite mean what it appears to say. Here's the next paragraph:
"The main finding of this study is that religious worship attendance is associated with a decreased risk of suicide attempts," said Daniel Rasic, who led the research. The findings were based on health surveys of 37,000 Canadians which included information about their spirituality - and specifically - their church attendance.
The article goes on to say that it's the people who actually attend church, rather than those who just consider themselves 'spiritual' who find themselves less inclined towards suicide. The study doesn't come to any conclusions as to why potentail suicides should be less suicidal as a result of attending church, but it's a good point to note, all the same.
