“…Critical public health approaches propose a broad range of overlapping concepts for understanding and responding to the effects of social inequality: These include social epidemiology (37,43,105), the eco-social or socio-environmental perspective (23,24,65,67,115,129), eco-epidemiology (128), and the risk environment framework (114,113,125). They call for a focus on social inequalities through concepts such as fundamental social causes (73)(74)(75)103), social stratification (78), social determinants of health inequality (63,76,78,80,125), income inequality (63), webs of causation (65), higher-order causal-level structural factors (87), upstream factors (86), discrimination, and racial disparities in health outcomes (42,66,71,79,123,144).…”
