Bacterial vaginosis is one of the most common genital tract infections among reproductive age group. The prevalence of bacterial vaginosis varies from country to country even in the same country it varies among populations of interest. Different social and sexual factors can contribute to the development of bacterial vaginosis. The aim of this study was to determine the prevalence of bacterial vaginosis and to identify the possible risk factors associated among pregnant women attending antenatal care in Tikur Anbessa University Hospital, Addis Ababa, Ethiopia.
Randomly selected 57 symptomatic and 195 asymptomatic pregnant women aged between 18 and 40 years visiting obstetric and gynecological clinic from November 2011 to April 2012 screenedusing Gram stain Nugent scoring system. Statistical analysis like univariate analysis to calculate frequencies and proportions, bivariate analysis to see association of selected exposure variables with the outcome variable, and multivariate analysis to check the association of possible factors with bacterial vaginosis by adjusting potential confounding factors was calculated using SPSS (Version 16.0).
The prevalence of bacterial vaginosis is 19.4% using Gram stain Nugent scoring system. In addition, prevalence of bacterial vaginosis is 31.6% and 15.9% among symptomatic and asymptomatic pregnant women respectively. A high percentage of bacterial vaginosis positive pregnant women were asymptomatic (63.3%). 36.7% bacterial vaginosis positive pregnant women reported abnormal vaginal discharge with or without unpleasant smell. Multiple lifetime sexual partner (OR: 8.6; 95% CI: 2.5, 29) and previous history of spontaneous abortion (OR: 5.9; 95% CI: 1.5, 23) had remained significantly associated with prevalence of bacterial vaginosis.
The prevalence of bacterial vaginosis is higher among asymptomatic pregnant women and associated with the factors previous history of multiple lifetime sexual partner and spontaneous abortion.
细菌性阴道病是育龄期女性中最常见的生殖道感染之一。细菌性阴道病的患病率因国家而异，即使在同一个国家，不同人群中的患病率也有所不同。不同的社会和性因素可能导致细菌性阴道病的发生。本研究的目的是确定埃塞俄比亚亚的斯亚贝巴提库尔安贝萨大学医院产前检查的孕妇中细菌性阴道病的患病率，并确定可能与之相关的危险因素。
2011年11月至2012年4月期间，从产科和妇科门诊随机选取57名有症状和195名无症状的18至40岁孕妇，采用革兰氏染色 Nugent评分系统进行筛查。使用SPSS（版本16.0）进行统计分析，如单变量分析以计算频率和比例，双变量分析以观察选定暴露变量与结果变量之间的关联，并进行多变量分析以通过调整潜在混杂因素来检查可能因素与细菌性阴道病之间的关联。
使用革兰氏染色Nugent评分系统，细菌性阴道病的患病率为19.4%。此外，有症状和无症状孕妇中细菌性阴道病的患病率分别为31.6%和15.9%。细菌性阴道病阳性的孕妇中很大一部分是无症状的（63.3%）。36.7%细菌性阴道病阳性的孕妇报告有异常阴道分泌物，伴有或不伴有异味。多个性伴侣（比值比：8.6；95%可信区间：2.5，29）和既往自然流产史（比值比：5.9；95%可信区间：1.5，23）与细菌性阴道病的患病率仍有显著关联。
无症状孕妇中细菌性阴道病的患病率较高，且与多个性伴侣和自然流产史等因素有关。
