BACKGROUND: TO identify the determinants of the geographic distributio
n of ischaemic heart disease (IHD) mortality in Spain. POPULATION AND
METHODS: Ecological study at the provincial level. Data are obtained f
rom the 1976-1980 vital statistics, the 1964-1965 Household Budget Sur
vey and the 1970 Population Census. RESULTS: Consumption of wine, chic
ken, fish, and vegetables, as well as illiteracy, explain 47% of IHD m
ortality. Consumption of wine alone exhibits a statistically significa
nt relationship (p < 0.05) with IHD mortality. Moderate consumption of
wine is negatively associated with IHD mortality, whereas higher cons
umption reveals a positive association. CONCLUSIONS: Results are consi
stent with those from an earlier study in Spain for the 1983-1987 peri
od.
