The problem with the corelation with homosexuality is that homosexuals are frequently up against violent prejudice, though less so in recent years. Being bullied can cause longterm psychological damage.

I know someone who endured really bad depression for a long time [1], and it's plausible that the major reason she didn't commit suicide was that she had a child.

Did deCatanzaro [2] look at whether whether people actually have children? Whether abandoning children has a high correlation with suicidality? Admittedly, it would be hard to tease out the causality in the latter.

[1] She was being treated for depression. What she actually has is Bipolar 2 (bipolar with so little mania that it's hard to notice), which is metabolically quite different from straight depression-- the right meds made a huge difference.

[2] That's how it's spelled on his website [3]-- there's no space between the e and the C.

[3] I think of the web + google as the larger part of my brain.
