mortality, suggested that "some pregnancies
that are destined to end in a neonatal or
first-week death in the United States terminate
in a fetal death in other countries."
The percentages of neonatal deaths in the
birth-weight groups 1,100-1,500 grams and
1,600-2,000 grams were relatively high in
many Latin American projects. These distributions
differed markedly from those in
California and Sherbrooke. Alsc the relatively
small numbers of neonatal deaths of
infants weighing 2,501 grams or more at
birth are puzzling.
The numbers of neonatal deaths in the
three subdivisions of San Juan Province
were sufficient to allow for consideration of
differences (Table 10 and Figure 29). In
the rural departments, 67.1 per cent of these
deaths had birth weights of 2,500 grams or
less, while the figure for the city of dan
Juan was 59.5 per cent. In the lowest weight
group (1,000 grams or less) there may be a
slight deficiency in the number recorded in
these rural departments, as the percentage
of 6.4 was lower than in the other areas;
some deaths may have been missed if the
infants were born at home and death certificates
were not filed. If complete data
were available, the percentage of low-birthweight
infants might be even higher in the
rural area.
These findings suggest that low-weight
births which in turn become neonatal
deaths may be more frequent in the rural
