Abstract
This study was conducted on 1600 full term
pregnant women, delivered at Ain Shams Maternity
Hospital, in February-June 1988. The aim is to set
the norms for birth weight in this groups of women.
The Criteria of Selection:
1. Singleton pregnancy.
2. Menstrual age between 38 and 42 weeks.
3. The neonats have been seen within 8 hours after
delivery.
4. Both parents were Egyptians from widely varying
socio-economic class.
5. Ir..fants with congenital anomalies or any gross
pathological condition were excluded, also
the infants whose mothers suffered from chronic
illness or pre-eclampsia.
The following procedure was followed:
As regards the mother:
1. careful history taking.
2. Clinical examination.
3. Grine analysis for sugar and protein. As regards the neonate:
1. Birth weight estimation within 8 hours after
delivery.
2. Determination of the sex.
In this study, the following results were obtained:
The mean birth weight was 3583 + 418 grams.
The birth weight increases with the increase
of the maternal age except in the age group
40 years may be due to the small number of
cases represented in this group, or due to sclerotic
lesions in the myometrial arteries which
leads to uteroplacental underperfusion.
The birth weight increased with parity and cases
of increased maternal hemoglobin level.
Male babies were found to be heavier than the
female babies.
The birth weight was increased with the increase
in the maternal weight and height. The Que t e 1 e t
index ( weight/height2 ) was used to determine
the women’s body mass at the time of delivery.
Maternal obesity was found to be one of the
factors responsible for the increase of the
infant’s birth weight as the infants of the
obese worr:en were on the average 236 grams heavier
than those of the non obese The incidence of the macrosomic babies was
found to be higher in the obese women than
in the non obese.
The birth weight was found to increase as the
social class is lowered except in the social
class I due to small number of cases represented
in this group, while it was decreased in the
cigarette smoking mothers in comparison with
the non smokers.
