Abstract

The aim of the present work was to determine the prevalence of IgG and IgM anti-Toxoplasma gondii antibodies and the factors associated to the infection in pregnant women attended in Basic Health Units in Rolândia, Paraná, Brazil. The sample was divided in two groups: group I (320 pregnant women who were analyzed from July 2007 to February 2008) and group II (287 pregnant women who were analyzed from March to October 2008). In group I, it was found 53.1% of pregnant women with IgG reactive and IgM non-reactive, 1.9% with IgG and IgM reactive, 0.3% with IgG non-reactive and IgM reactive and 44.7% with IgG and IgM non-reactive. In group II, it was found 55.1% with IgG reactive and IgM non-reactive and 44.9% with IgG and IgM non-reactive. The variables associated to the presence of IgG antibodies were: residence in rural areas, pregnant women between 35-40 years old, low educational level, low family income, more than one pregnancy, drinking water which does not originate from the public water supply system and the habit of handling soil or sand. Guidance on primary prevention measures and the quarterly serological monitoring of the pregnant women in the risk group are important measures to prevent congenital toxoplasmosis.O objetivo deste trabalho foi determinar a prevalência de anticorpos IgG e IgM anti-Toxoplasma gondii e os fatores associados à infecção em gestantes atendidas nas Unidades Básicas de Saúde de Rolândia, Paraná, Brasil. A amostra foi dividida em dois grupos: grupo I (320 gestantes, analisadas entre julho de 2007 e fevereiro de 2008) e grupo II (287 gestantes, analisadas de março a outubro de 2008). No grupo I, foram encontrados 53,1% de gestantes IgG reagente e IgM não reagente, 1,9% de IgG e IgM reagentes, 0,3% de IgG não reagente e IgM reagente e 44,7% de IgG e IgM não reagentes. No grupo II foram 55,1% de IgG reagente e IgM não reagente e 44,9% de IgG e IgM não reagentes. As variáveis associadas à infecção foram: residência em área rural, gestantes entre 35-40 anos de idade, baixa escolaridade, baixa renda familiar, mais de uma gravidez, consumo de água não proveniente do sistema de abastecimento público de água e hábito de manipular terra ou areia. As orientações sobre medidas de prevenção primária e o acompanhamento sorológico trimestral das gestantes no grupo de risco são medidas importantes para prevenir a toxoplasmose congênita.
