To analyse the epidemiological aspects of sexually transmitted diseases (STD) among women who have sex with women (WSW) in São Paulo, Brazil.
A cross-sectional study with interviews and analysis of clinical and gynaecological tests in women, by means of a convenience sample. Characteristics were gathered according to age, sociobehavioural profile, reproductive life and sexuality.
The study included 145 women. They started sexual activity at an average age of 16.9 years, and 23.4% of them had had heterosexual relations during the preceding year, with a relatively low frequency of condom use. In sexual relations with women, 54.5% used condoms when they shared sex toys. A previous STD was reported by 38% of them. The following STD were diagnosed: trichomonas (3.8%), bacterial vaginosis (33.8%), fungi (25.6%), Chlamydia (1.8%), hepatitis B (7%), hepatitis C (2.1%), abnormal Pap smear (7.7%), human papillomavirus (6.2%) and HIV (2.9%).
In this study, many WSW did not report a single risk behaviour, but often reported a combination of several potential risk factors. Therefore, one cannot speak of high or low-risk behaviour for STD/HIV, but rather of multiple-risk behaviour. It is evident that there is a need for healthcare professionals to be correctly informed and sensitive towards the healthcare of WSW.
分析巴西圣保罗与女性发生性行为的女性（WSW）中性传播疾病（STD）的流行病学特征。
采用便利抽样法对女性进行访谈，并分析其临床和妇科检查结果，开展横断面研究。根据年龄、社会行为特征、生殖生活和性行为收集相关特征数据。
该研究纳入了145名女性。她们开始性行为的平均年龄为16.9岁，其中23.4%的女性在前一年有过异性性行为，且使用避孕套的频率相对较低。在与女性的性行为中，54.5%的女性在共用性玩具时使用避孕套。38%的女性曾患过性传播疾病。诊断出的性传播疾病如下：滴虫病（3.8%）、细菌性阴道病（33.8%）、真菌病（25.6%）、衣原体感染（1.8%）、乙型肝炎（7%）、丙型肝炎（2.1%）、巴氏涂片异常（7.7%）、人乳头瘤病毒（6.2%）和艾滋病毒（2.9%）。
在本研究中，许多与女性发生性行为的女性未报告单一的风险行为，但常报告多种潜在风险因素的组合。因此，不能简单地将其性行为定义为性传播疾病/艾滋病毒的高风险或低风险行为，而应视为多重风险行为。显然，医疗保健专业人员需要正确了解并对与女性发生性行为的女性的医疗保健保持敏感。
