This is often attributed to the methods used, as men typically choose more lethal means, resulting in higher completion rates. C.

The frequency and success of suicide attempts are generally analyzed with a broader demographic perspective, not specifically focused on adolescent parents. D. Adult men are more likely to complete suicide, but women generally attempt suicide more frequently than men. The completion rate for suicide is higher among men compared to women.
