Yes I've heard that there is new research that shows oppression gives you HIV.

Are you saying people are being oppressed into having unprotected sex?

or that they receive fewer opportunities for education and distribution of said protection (eg, a richer school may have free condom distribution, but a poorer one does not?). Maybe because cultures of "Abstinence" (eg, teach them abstinence and dont give them condoms/protection, then wonder why they get diseases)...

This is all supposition, I'll let others lay down the facts.
