Background. - Persistent diarrhea (PD) is recognized as a major cause
of morbidity and mortality in the developing world. Patients and metho
ds. - The files of all children, less than 5 years of age, admitted in
1990 and 1991 for diarrhea persisting from 14 to 30 days have been re
trospectively analysed. Socio-economic factors, history of disease, ch
anges in feeding, nutritional status and clinical data of the DP have
been specially recorded. Results. - During these 2 years, 74 children
were admitted (93% of them were less than 12 months old). Two-thirds o
f the patients were issued from suburban-living poor families. DP was
more frequent during September and October (42%), the usual period of
malnutrition. Although only 23% of the mothers had reported history of
acute diarrhea, 35% of them did not exclude it. Sixty-nine percent of
the children were breast-fed and 82% were bottle-fed before 12 months
of age. Dietary intake was stopped during the acute episode in 52% of
cases. There were no chronic malnutrition, but 69% of patients were s
uffering from acute malnutrition. Dehydration was present in most case
s and was severe in 33% of them. Death occurred in three children. Con
clusions. - These results show that, among usual risk factors of PD bo
ttle-feeding, diet errors and history of acute diarrhea seem to be par
ticularly frequent in this Tunisian population.
