Locating Politics in Social Epidemiology

Abstract

Recent social epidemiologic research has focused on the impact of politics, expressed as political traditions or parties and
welfare state characteristics, on population health. Guided by a political economy of health and welfare regimes framework,
this chapter synthesizes this growing body of evidence and locates 73 empirical and comparative studies on politics and health
meeting our inclusion criteria. Two major research programs – welfare regimes and democracy – and two emerging programs –
political tradition and globalization – are identified. Primary findings include: (1) left and egalitarian political traditions
on population health are the most salutary, consistent and substantial; (2) the health impacts of advanced and liberal democracies
are also positive and large; (3) welfare regime studies, primarily conducted amongst wealthy countries, find that Social Democratic
regimes tend to fare best with absolute health outcomes yet inconsistently in terms of relative health inequalities; and (4)
globalization defined as dependency indicators such as trade, foreign investment and national debt is negatively associated
with population health.
