Introduction The decrease morbi-mortality gastroenteritis in is relate
d to the factor responsible largely for the fall in infant mortality a
nd mortality from communicable diseases in developing countries. Never
theless, diarrhea is still a considerable public health problem in the
se countries, especially among children under 5 years old. Objectives
To describe some aspects of the of gastroenteritis epidemiology among
children up to 5 years old, resident in areas of S. Paulo county. Mate
rial and Method A probabilistic sample of children up to 5 years old w
as studied ( n=468). The epidemiological survey was undertaken in five
areas S. Paulo county (Brazil) from March 1986 to May 1987. Data were
obtained through household interviews once a month over a year. Resul
ts During the follow-up 139 diarrhea episodes were registered, with a
mean duration of 5.5 days. Twenty percent of the diarrhea events were
followed by at least one other case in the household The incidence of
gastroenteritis was 2.78 episodes per 100 children/month. The highest
incidence affected the children of up to 2 years of age. In 46.1% of t
he gastroenteritis episodes medical assistance was not sought, the chi
ldren were treated by their mothers or not at all; 51.8% of the diarrh
ea events were attended to by the primary health care service, and onl
y 2.1% were attended to by a hospital. No child died as a consequence
of diarrhea. Of the therapeutical interventions used the most frequent
were oral rehydration (25.2%) and oral rehydration with antibiotics (
11.5%). Various socio-economic and personal background factors such as
living conditions, water supply, sewarage, coverage;family income per
capita and prior history of frequent gastroenteritis were associated
with a higher incidence of gastroenteritis. Discussion The results see
n to reflect the tendency of morbi-mortality by gastroenteritis to dec
rease in S. Paulo county during the 1980's when hospital treatment of
diarrhea presented a considerable reduction. This tendency must be obs
erved closely, because it will influence the changes to be mode in the
kind of demand for medical care.
