[Welfare State and public health: a relationship that needs to be updated].

Human health has improved throughout the 20th century, at the same time that the Welfare State was consolidated. This paper explores the current relationship between the welfare state and public health. The essential functions of public health are exercised as part of the State, and currently the main challenge is to ensure that health is protected and promoted through different public policies, including employment. Studies assessing the health effect of different types of welfare state are contradictory, but when the impact of specific policies, such as unemployment benefits, is considered, the results are positive and consistent. However, the current crisis of the Welfare State hampers its continuity, largely due to changes in the labour market, with more flexible and insecure jobs.
