The two major negative effects of low social-economic status on health that I commonly see mentioned is increased stress and reduced amount of cooping mechanics that provide protection.

The human body is pretty able to withstand most injuries, viruses, bacteria and so on. The more stressed a person is the less the body is able to do that recovery. In addition, if and individual is low on the socio-economic scale they might not have available cooping mechanics like resting, taking a day of, or access to social support. A lack of cooping mechanics is also a source for stress, making the body prioritizing other things than recovery.
