OBJECTIVES
The study aimed to test if there was an association between prevalent bacterial vaginosis (BV) and women reporting that their partner had other partners at the same time (partner concurrency). This association has not been assessed in a longitudinal cohort.
METHODS
The Longitudinal Study of Vaginal Flora recruited a cohort of 3620 non-pregnant women aged 15-44 years who presented for routine primary healthcare at 12 clinics in Birmingham, Alabama. Behavioural questionnaires and vaginal smears were obtained quarterly for a year and BV was defined by a Nugent score 7 or higher as well as Amsel criteria. Mixed effects logistic regression was used to assess the relationship between prevalent BV and reporting that one's partner had other partners in the preceding 3-6 months time interval.
RESULTS
Nugent score prevalent BV was associated with both reporting that one's partner definitely (adjusted OR (aOR) 1.5; 95% CI 1.2 to 1.8) and possibly (aOR 1.5; 95% CI 1.2 to 1.8) engaged in partner concurrency in the preceding 3-6 months time period. Prevalent BV diagnosed by Amsel criteria was similar.
CONCLUSIONS
A diagnosis of prevalent BV was associated with reporting that one's partner possibly or definitely engaged in partner concurrency.
目的
本研究旨在检验细菌性阴道病（BV）现患与女性报告其伴侣同时拥有其他性伴侣（伴侣同时性）之间是否存在关联。这种关联尚未在纵向队列研究中进行评估。
方法
阴道菌群纵向研究招募了 3620 名年龄在 15-44 岁之间的非孕妇，她们在阿拉巴马州伯明翰的 12 个诊所进行常规初级保健。在一年内每季度进行行为问卷调查和阴道涂片检查，BV 的定义为 Nugent 评分≥7 分和 Amsel 标准。采用混合效应逻辑回归评估现患 BV 与报告其伴侣在前 3-6 个月时间间隔内有其他性伴侣之间的关系。
结果
Nugent 评分现患 BV 与报告其伴侣在前 3-6 个月时间间隔内肯定（调整后的比值比[aOR] 1.5；95%CI 1.2 至 1.8）和可能（aOR 1.5；95%CI 1.2 至 1.8）发生伴侣同时性均相关。Amsel 标准诊断的现患 BV 也是如此。
结论
现患 BV 的诊断与报告其伴侣可能或肯定发生伴侣同时性有关。
