Excessive influence of religion leads to poverty, poor health, and a high child mortality rate? Do you have any sources to back this besides a general feeling that religion is "bad"?
TED Talk Hans Rosling: Let my dataset change your mindset:
Religion has very little to do with the number of babies per woman. All the religions in the world are fully [able] to maintain their values and adapt to this new world. </quote>

Yes religions can adapt, but of course they don't want to and needn't, so Rosling's reasoning isn't convincing. Utah has the highest birth rate in the US. I doubt that has very little to do with Mormonism.
It's not based on a general feeling. It's based on the fact that resources are limited. Any religion that successfully promotes "be fruitful and multiply" will certainly bump against that limit eventually. I can only suspect in any particular case because something else besides religion could be the main contributor to the bad things.
