[Need for systematic HIV serological study during pregnancy].
BACKGROUND
To evaluate human immunodeficiency virus (HIV) screening usefulness in pregnancy and to know the prevalence of this infection in an urban area of Spain.


METHODS
Routine prenatal screening for antibodies to HIV was offered to pregnant women from Fuenlabrada-Leganés Health Care Area (Madrid) from 1992 to 1995. Unlinked anonymous screening of HIV was done with the sera from women refusing the assay or if it had not been offered.


RESULTS
HIV prevalence was 0.28% (CI: 95%; 0.19 to 0.40) in the 11.021 pregnant women group studied. 87.1% pregnant seropositive women were detected by consented screening. 55.6% of them recognized risk behavior (73.33% by intravenous drug use) and 44.4% did not do it. With a second anamnesis in this group 75% admitted risk conducts and 25% confirmed their ignorance about them.


CONCLUSIONS
HIV seropositive screening in pregnant women selected only by risk behavior may be unsuccessful. For that reason, it is more convenient the perform a routine test for detection of HIV antibodies after informed consent in high prevalence areas of HIV infection.
