INTRODUCTION
The aim of the present study was to analyze the exposure to risk factors for toxoplasmosis disease and the level of knowledge in pregnant women who were treated by the Public Health Care System (SUS) from October 2007 to September 2008 in Divinópolis City, Brazil.
METHODS
We analyzed 2,136 prenatal exams of pregnant women that were treated from October 2007 to September 2008.
RESULTS
Out of the 2,136 pregnant women evaluated, 200 answered a quantitative questionnaire; 49.5% were seropositive for immunoglobulin (Ig) G and 3.6% for IgM. Comparative analysis of congenital toxoplasmosis cases were evaluated in 11 regions and showed an irregular distribution (p < 0.01). This difference was also observed among the pregnant women observed in each location. The results from the questionnaire show that 93% of the pregnant women had no knowledge about toxoplasmosis, and 24% presented with positive serology, but no clinical manifestation. Analysis for pregnant IgG-positive women and the presence of pets showed a statistically significant correlation (p < 0.05), suggesting that the transmission of this disease might occur in the domestic environment.
CONCLUSIONS
We suggest the implementation of a triage program for pregnant women and health education to encourage their use of SUS services.
简介
本研究旨在分析巴西迪维诺波利斯市 2007 年 10 月至 2008 年 9 月期间接受公共医疗保健系统（SUS）治疗的孕妇感染弓形虫病风险因素的暴露情况和知识水平。
方法
我们分析了 2007 年 10 月至 2008 年 9 月期间接受治疗的 2136 例产前检查的孕妇。
结果
在评估的 2136 名孕妇中，有 200 名回答了定量问卷；49.5%的孕妇 IgG 呈阳性，3.6%的孕妇 IgM 呈阳性。对 11 个地区的先天性弓形虫病病例进行了比较分析，结果显示分布不均匀（p < 0.01）。在每个地点观察到的孕妇中也观察到了这种差异。问卷调查结果显示，93%的孕妇对弓形虫病一无所知，24%的孕妇血清学呈阳性，但无临床表现。对 IgG 阳性孕妇和宠物的分析显示存在统计学显著相关性（p < 0.05），这表明该疾病可能在家庭环境中传播。
结论
我们建议为孕妇实施分诊计划和健康教育，鼓励其使用 SUS 服务。
