In order to define the main diseases of the elderly and a possible cha
nges of mortality causes at Hospital General of Mexico, SSA, the autho
rs studied 586 autopsy reports of individuals over sixty years old, de
ceased between 1960 and 1965 and of 625 individuals of similar charact
eristics deceased between 1981 and 1985. The analysis of diseases show
ed qualitative and quantitative changes in the ten principal causes of
death at each period: some of the most frequent diseases in the 60's,
for instance, amebiasis, were not included among the then principal c
auses of death in the 80's. On the other hand, malignant neoplasms per
sisted as one of the principal death causes in both periods, but the m
ost frequent carcinoma in the 60's, gastric carcinoma, was substituted
in the 80's by bronchogenic carcinoma. This study suggests that great
technical and sanitary interventions are necessary to promote health
of third age persons, an increasing but poorly protected population in
our country.
