Abstract

In their article in this issue of the Journal (Am J Epidemiol. 2013;178(6):843-849), Galea and Link identify important heuristics for our discipline. In this commentary, I build upon their ideas by arguing that 1) social epidemiology has become an Asian, European, Latin American, and African rather than just North American endeavor, 2) realism is better suited to social epidemiology than positivism, 3) more work on social mechanisms (social class relations, racial discrimination) is needed to increase the explanatory power of social epidemiology, 4) increased attention on (social) causal models will generate more innovative social interventions, and 5) social interventions should be conducted in full partnerships with affected populations.
