Estudo de soroprevalência de toxoplasmose em gestantes atendidas na rede municipal de saúde de Vitória, ES

Abstract

Toxoplasmosis is prevalent in Brazil. The infection during pregnancy can affect the fetus and cause sequelae in the child. Objectives: To determine seroprevalence of toxoplasmosis in pregnant women attending primary health cares in Vitória Municipality and evaluate correlate factors for the infection. Methods: A cross-sectional study, performed from January to December 2006, in 1153 pregnant women attending antenatal care in public clinics from the six health areas. A face-to-face interview with sócio-demographic, behaviors and clinics was performed; and serology for IgG, IgM and avidity of IgG by quimiluminescence (Diasorin) and eletroquimioluminescence (Biolab-Merrieux). Results: Prevalence of toxoplasmosis was 73.5% (CI 95% 70.95%-76.05%) and 1.3% (CI 95% 0.65%-1.95%) of acute infection. Considering avidity of IgG, prevalence of acute infection was 1.1% (CI 95% 0.5%-1.7%). A total of 26.5% (CI 95% 23.9%-29.0%) pregnant women were susceptive to toxoplasmosis and 72.2% (CI 95% 69.6%-74.8%) immunes. IgG antibodies were independent associated to buying meat in free markets [1.78 (CI 95% 1.02-3.13), and IgM antibodies during pregnancy were associated to lower education (up to four years) [5.30 (CI95% 1.67-16.83)]. Conclusions: These results corroborate the importance of earlier antenatal care and the inclusion of avidity test in toxoplasmosis diagnosis. It is requested a better sanitary control concerning the commerce of meat without registration.
