Avoidable causes of death and their effects on life expectancy. A socio-demographic interpretation. The case of the northern frontier, 1980-1990

"This study forms part of a] research project on the health-disease-death process along the Mexican] Northern Frontier--a by-product of the socio-economic structure of a specific social formation that determines disease and death--to support regional and sectorial design of policies and actions for the improvement of health conditions for its population.... An important finding is a 4.1 year increase of life expectancy due, among other causes, to a slight decrease in avoidable death causes, although these still produce about 50% of deaths."
