In a retrospective study, teenage Asian pregnancies with gestational diabet
es managed over a 4-year period were compared with a group of age and parit
y matched controls (2 for each study case) to determine the incidence of ge
stational diabetes and its impact on the pregnancy outcome. The incidence o
f gestational diabetes in teenage pregnancy was 5.4 % (33/611), and account
ed for 1.4 % of all the cases of gestational diabetes. There was no differe
nce in the maternal anthropometric parameters or antenatal complications, b
ut the study group had a higher incidence of postpartum haemorrhage (p = 0.
010), greater amount of estimated blood loss at delivery (p = 0.016), a tre
nd towards a higher incidence of large-for-gestational age infants, a highe
r incidence of admission to the neonatal unit (p = 0.024), mostly due to me
conium-stained liquor for observation (p 0.014), and a tower first minute A
pgar score (p = 0.012). Our findings support the recommendation that in eth
nic groups with a high prevalence of diabetes, universal as opposed to age-
limited screening for gestational diabetes should be undertaken. (C) 1998 J
