BACKGROUND: TO determine the need of prenatal screening far toxoplasmosis i
n our hospital from a seroepidemiological point of view.
PATIENTS' AND METHODS: The prevalence of IgG anti-T. gondii was retrospecti
vely analyzed in 7.090 women of childbearing age attended in the Hospital C
linic of Barcelona from February 1992 to April 1999. The association among
the seroprevalence and the variables year, age, birthplace (province of Bar
celona/other provinces) and place of residence (urban/rural) was analyzed,
RESULTS: A decreasing trend was observed in the prevalence (p < 0.001), cur
rently being < 40% in the average women between 15 and 45 years, Infection
was also directly related to age of women (p < 0.001) and birthplace out of
the province of Barcelona (p = 0.001). Habitat (rural or urban) was not as
sociated with seroprevalence.
CONCLUSIONS: Prenatal screening for toxoplasmosis is necessary due to the h
igh rate of seronegative women exposed to infection and the evidence of a h
igh number of primoinfections in the childbearing period.
