For example, there are only a small number of studies that look at whether the effect of unemployment on health outcomes is different in countries with strong social protection versus those with weaker schemes. There is also a need for more evidence on the longterm effects of unemployment on health outcomes, particularly when unemployment persists over longer periods of time. This particularly true in the case of the most recent economic downturn as health care system’s capacity to cope with changing health care needs may be affected by the resource constraints that have been imposed in a large number of countries.
