Resumen:
Background: Low weight and premature deliveries arouse
clinical interest concerning the survival of newborns. The
determinants of birth weight among Spanish natives and
immigrants may differ. Research which considers maternal
origin and associated factors such as age and parity is
important.
Aim: This study analyses and models the influence of the rapid
and intense arrival of immigrants in Spain on birth weight
variation.
Method: Data on deliveries from the Spanish National Institute
for Statistics (n ¼ 9 443 882) are analysed regarding low birth
weight, premature births and other variables. The inter-
relation among these variables was interpreted by means of
logistic regression models.
Results and conclusions: The birth weight has decreased since
1980 in Spain, but has slightly recovered in recent years.
Meanwhile the percentage of foreign maternities increased to
17.3% in 2010. Logistic regression models assess the different
influence of variables known to determine low birth weight
(weeks of gestation, sex, etc.) and other maternal
characteristics (age at delivery, professional activity, etc.).
The progressively greater contribution of foreign women to
total births in Spain and their differential numerical input to
the various risk groups have slowed the pattern of reduction
in the mean weight of newborns in this country.
