In order to determine the prevalence of bacterial vaginosis (BV) among women attending a family health Center and to evaluate the accuracy of Amsel's diagnostic procedure relative to Nugent scoring for diagnosing this condition, we obtained vaginal specimens from 100 women under 50 years attending a FPC from April to November of 2006. Women were enrolled consecutively on a schedule basis and were not selected by symptoms of genital infection. VB was diagnosed in 32% women, without significant differences by age (p=0,114). 87.5% women declared one sexual partner in the last 6 months. The Amsel's method had a sensitivity of 62.1%, and a specificity of 92.3%, with positive and negative predictive values of 81.8% and 83.3% respectively, being the presence of clue cells the most accurate parameter. Nevertheless, the lack of microscopes in the clinical practice limits the use of the Amsel's criteria. In conclusion, VB is a prevalent infection in the study population, being not associated with age or sexual activity. Diagnosis should be performed by the Nugent method.
为了确定在一家家庭健康中心就诊的女性中细菌性阴道病（BV）的患病率，并评估阿姆斯勒诊断方法相对于用于诊断该疾病的纽金特评分的准确性，我们于2006年4月至11月从一家家庭健康中心的100名50岁以下女性中获取了阴道标本。女性按预定计划连续入组，并非根据生殖器感染症状进行选择。32%的女性被诊断为BV，年龄方面无显著差异（p = 0.114）。87.5%的女性称在过去6个月中有一个性伴侣。阿姆斯勒方法的敏感性为62.1%，特异性为92.3%，阳性预测值和阴性预测值分别为81.8%和83.3%，线索细胞的存在是最准确的参数。然而，临床实践中缺乏显微镜限制了阿姆斯勒标准的使用。总之，BV在研究人群中是一种常见感染，与年龄或性活动无关。诊断应采用纽金特方法。
