[Results of screening for HIV antibodies in pregnant women, clients of infertility clinics and abortion clinics in the Amsterdam region in 1990].

In 1988, a study was started in three Amsterdam hospitals to investigate the HIV prevalence among pregnant women. In 1989 more hospitals and also midwife clinics were included in the study. From 1990 onwards all hospitals in Amsterdam, 22 midwife practices, 2 abortion clinics and 3 clinics for infertility problems participated. The study was carried out on a voluntary basis. Of the 8423 eligible pregnant women in 1990, 7823 women (92.9%) participated and 600 women (7.1%) decided not to participate. Eight women were found to be positive for HIV antibodies (0.10%, 95% CI 0.09-0.11) (1988: 0.28%; 1989: 0.10%). Of these 8 HIV-seropositive women 5 belonged to one of the known AIDS risk groups and 3 women were not aware of any risk-bearing behaviour. Of the 5 women from an AIDS risk group 2 denied a risk factor at their first visit to the clinic. One of the 8 women was positive for antibodies against HIV-2. Among the 719 women tested in the abortion clinics (23.3% refusers) 3 women were positive for antibodies against HIV-2 and I woman against HIV-I (prevalence 0.56%; 95% CI 0.52-0.59). Of the 476 women tested in the clinics for infertility problems no women were found positive for HIV antibodies. During the period 1988-1990, a total of 19 women were found HIV-seropositive in the screening program for pregnant women. Of the 13 women tested within the first 20 weeks of pregnancy 4 women decided to terminate their pregnancy.(ABSTRACT TRUNCATED AT 250 WORDS)
