摘要：Objective: The purpose of this study was to assess the association between previous m.ternal Toxoplasm. gondii (T gondii) infection and risk of fetal death. Study design: This was a population-based prospective cohort of 29,912 pregnant wom.n without acute T gondii infection in Norway. Results: In the study population, 2937 (9.8% ) wom.n had evidence of previous m.ternal T gondii infection, and 299 (1.0% ) had fetal deaths. We found no association between previous T gondii infection and risk of fetal death at ≥ 20 weeks of gestation. We did find a trend for an increased risk of fetal death at ≥ 16 and < 20 weeks of gestation. However, we noted no association between previous T gondii infection and risk of fetal death at all birth weight categories (≥ 1000, ≥ 500 and <1000, and < 500 g). Conclusion: These data do not indicate an increased risk of fetal death at ≥ 20 weeks of gestation in wom.n with previous m.ternal T gondii infection.
