[Environmental factors during early life and socioeconomic status in the present: which is more important for cardiovascular mortality in Spain?].
BACKGROUND
To examine whether provincial mortality from ischaemic heart disease and cerebrovascular disease in Spain in 1991-1995 is associated with infant mortality in 1930-1934, independently of illiteracy (an estimator of socioeconomic status) in 1991.


METHODS
Population-correlation study.


RESULTS
Infant mortality is correlated with mortality from ischaemic heart disease (r = 0.38; p < 0.01) and cerebrovascular disease (r = 0.41; p < 0.01). When adjusting for illiteracy rate in 1991, the correlation of infant mortality with ischaemic heart disease mortality is r = 0.01 (p = 0.93), and with cerebrovascular disease mortality is r = 0.25 (p = 0.08).


CONCLUSIONS
Ischaemic heart disease and cerebrovascular disease mortality are moderately associated with infant mortality during the 1930s. This association might be explained by present socioeconomic status.
