Objectives: Because most HIV-infected women are of reproductive age, we inv
estigated whether their reproduction planning was affected by their HIV dia
gnosis.
Design: The European women study is a prospective, multicentre cohort of 48
5 HIV-infected women with a known interval of seroconversion.
Methods: The incidence of pregnancy was measured with person-time methods.
Generalized estimating equation analysis was used to determine risk factors
for pregnancy and pregnancy outcomes.
Results: In 449 women, the age-adjusted incidence of pregnancies decreased
from 8.6 before HIV diagnosis to 8.2 and 6.0 per 100 person-years in 0-4 an
d over 4 years after HIV diagnosis, respectively (P = 0.14). The proportion
of induced abortions increased from 42% before to 53% alter HIV diagnosis
(P < 0.05). The risk of spontaneous abortion did not increase as a result o
f HIV infection. Since 1995, the proportion of births increased (P = 0.009)
, whereas that of induced abortions decreased (P = 0.01) compared with earl
ier years. An increased risk of pregnancy after HIV diagnosis was found in
northern and central European women compared with southern European women;
there was a lower risk in single women than in women with a steady partner.
Of all pregnant women, single women, women between 15 and 25 years of age,
and women with multiple partners were at increased risk for induced aborti
on both before and after HIV diagnosis.
Conclusion: The incidence of pregnancy decreased with HIV disease progressi
on. Pregnancies after HIV diagnosis appear to be related largely to social
and cultural attitudes. The number of induced abortions was significantly i
