BACKGROUND: Toxoplasmosis is a parasitic infection usually asymptomatic, but with important consequences when it affects the fetus and immunocompromised. However, even in areas of high prevalence little is known about the problem among pregnant women who receive little or no information on prevention and risk factors for transmission in prenatal consultations. OBJECTIVE: To evaluate the knowledge of pregnant women on toxoplasmosis in association with exposure to risk factors, socio-demographic and prenatal care. METHODOLOGY: We conducted a cross-sectional study analytic, from January to May 2011, the Santa Casa de Misericórdia do Pará, regional reference in maternal and child health, with 307 mothers of a total of 2,000 hospitalized in the period . Data were collected through interviews with plug consent protocol, three times a week, between 6-48 hours after delivery, stored in a database. RESULTS: According to the responses to each item in the form of protocol, the sociodemographic data showed the predominance of (p<0.0001), aged 19-24 years (n = 118/296, 39.9%), Pará (n = 290/305, 95.1%), residents in the metropolitan region of Belém (n = 191/307, 62.2%) of mixed ethnicity (n = 156/307, 50.8%), an education incomplete elementary (n = 106/307, 34.5%), Catholic (n = 148/307, 48.2%), in a consensual union (n = 174/307, 56.7%) who identified themselves as housewives (n = 171/299, 57.2%) and income from 1 to 3 minimum wages (234/281, 83.3%), data regarding prenatal care was higher (p <0, 0001): those who received prenatal care (n = 281/295, 95.3%), with the first quarter (n = 97/157, 61.8%), performing 1-3 consultations with a doctor (n = 134/256, 52.3%) in the same way with nurses (n = 152/249, 61%) who presented to the Determine HIV- negative (n = 253/259, 97.7%), VDRL non-reactive (n = 231/237, 97.5%), HIV negative (n = 226/262, 86.3%) underwent obstetric ultrasonography (n = 280/298, 94%) and serological tests, predominantly toxoplasmosis serology (n = 122/307, 39.7%) in relation to risk factors were significant (p <0.0001) information regarding the consumption of meat (n = 305/307, 99.3%) and cooked (n = 289/305, 94.5%), contact with animals, especially dogs (n = 158/307, 51.5%) and cats (n = 121/307, 39.4%), the use piped water (n = 169/297, 56.9%) and filtered (n = 55/129, 42.6%) and does not reside in wetlands (n = 231/292, 79.1%). In relation to knowledge about toxoplasmosis and their associations, it was observed that: 76.9% do not know (n = 210/273, p <0.0001), this knowledge is independent of the implementation of prenatal care (p = 0.0421 ), since only 25% of those who received prenatal care know, and 100% of those who did not know, independent of education (p = 0.0004), with a chance of not knowing (OR) 3.9 times higher in patients with less education, not knowing toxoplasmosis is related to family income (p = 0.0089) and have an income below Minico salary increases (OR) 10.7 on the chance it unknown; guidelines on infectious diseases in pre-natal non- improved knowledge about toxoplasmosis (p = 0.4586) and there was no correlation between knowledge of toxoplasmosis and risk factors, such as cooking meat (p = 0.8743), contact with animals (p = 0.9344) and treatment Water consumption (p = 0.1990). CONCLUSIONS: It is actually the lack of knowledge about toxoplasmosis among pregnant women of the country's largest public maternidde in an area of high prevalence of this disease. No approach to prenatal care on knowledge and attitudes of pregnant women about toxoplasmosis. The cautionary statements should be part of prenatal care, and this information should include a set of actions undertaken by public education and global health, coupled with professional training.
