You make a good point about Russian Muslims being healthier than the rest of the population due to their more stringent religious code regarding alcohol. You see this same sort of disparity in Africa, where HIV rates are much, much lower in the Arab north than they are even in places like West Africa, where rates of infection are modest compared to the the countries around South Africa. Presumably, this is in part due to cultural prohibitions against promiscuity and, let's be blunt, oppression of women. Of course, socialist countries often had a puritanical streak reminiscent of certain aspects of the Islamic world. The solution isn't a return to traditionalism however, but a combination of affluence, education, and easy access to health care and contraception.
