[The prevalence of HIV in pregnant women at 3 outpatient clinics in Amsterdam].

Pregnant women who were seen in 3 hospitals in Amsterdam were tested for antibodies to HIV, after informed consent. Out of 2,308 eligible pregnant women, 2,094 (90.7%) participated by name and 21 (0.9%) anonymously; 193 (8.4%) refused to participate. Among refusers there were significantly more women with a non-Dutch nationality or born in other countries. Of 2,115 pregnant women, 6 were found to be HIV-infected (0.28%, 95% confidence interval (0.05-0.51). Among women who at their first prenatal visit reported no AIDS-risk factor either for themselves or their partner(s), the HIV prevalence was 1/1,893 (0.05%) and among women with such risk factor the prevalence was 5/180 (2.78%). Three of the seropositive pregnant women knew before they were tested that they were HIV-infected. Of the 6 HIV-infected women one had a spontaneous abortion and the 4 women who were tested within the period when therapeutic abortion was still possible, decided to continue their pregnancy.
