This study aimed to estimate prevalence of vulvovaginal candidiasis (VVC) and recurring VVC (RVVC).
An online omnibus survey was administered to 6,010 women aged 16 and older in 6 countries.
We analyzed surveys from 6,000 women. Depending on the country, between 29% and 49% of participating women reported having a health care provider-diagnosed vaginal yeast infection during their lifetime. More than one fifth of women reporting one vaginal yeast infection also reported a 12-month period with 4 or more infections (RVVC) (overall 9%). The cumulative probability of RVVC after an initial vaginal yeast infection was very high. By age 25 years, the probability was 10% for women having had 1 initial yeast infection. By age 50 years, it was 25%.
The overall rates of VVC and RVVC were high and consistent with previous findings. Results were consistent across countries with the exception of France, which had a lower rate of VVC. This may reflect differences in risk behavior, response to infection, or sampling biases. Recurring VVC is a significant health problem in western countries, and the probability that VVC will progress to RVVC is high.
本研究旨在估计外阴阴道念珠菌病（VVC）和复发性 VVC（RVVC）的患病率。
在 6 个国家，对 6010 名 16 岁及以上的女性进行了在线综合调查。
我们分析了来自 6000 名女性的调查。根据国家的不同，有 29%至 49%的参与女性报告在其一生中曾由医疗保健提供者诊断患有阴道酵母菌感染。超过五分之一报告曾有过一次阴道酵母菌感染的女性还报告了 12 个月内有 4 次或更多次感染（RVVC）（总体为 9%）。初次阴道酵母菌感染后 RVVC 的累积概率非常高。在初次阴道酵母菌感染后，25 岁之前的概率为 10%，而在 50 岁时为 25%。
VVC 和 RVVC 的总体发生率较高，与先前的研究结果一致。除了法国的 VVC 发病率较低外，各国的结果基本一致。这可能反映了风险行为、对感染的反应或抽样偏差方面的差异。复发性 VVC 是西方国家的一个严重健康问题，VVC 进展为 RVVC 的可能性很高。
