Achieving Health for All: Primary Health Care in Action
From chapter 2 of the book, on life expectancy and GDP (Preston curve)
The list of best-performing countries is still limited because it is often the case that a country looks like it is deriving a high health output from minimal economic growth simply because it has had a prolonged spell of economic stagnation, and health improvements are simply occurring as a result of secular trends set up by past introductions of public health technology. Thus, what often appear to be “top-performing” countries in climbing the Preston Curve frequently appear successful because of stagnant and barely positive economic growth. The project of empirically identifying exemplary countries achieving good health at low cost or “punching above their weight” needs to reexamine foundational assumptions about (1) whether countries are actually engaged in transforming economic growth into better health and (2) what counts as a valid comparison group for a given country at a given time depending on its starting LEB.
