The goal of this study was to assess condom use and related behaviour in young women in Vitória, Brazil. From March to December 2006, a cross-sectional sample of women aged 18-29 years was recruited into a population-based study. Risk behaviours for HIV and sexually transmitted infections (STIs) were surveyed. Condom use at last intercourse was assessed as a principal outcome describing protective sexual behaviour. Of 1200 eligible women identified, 1029 (85.8%) enrolled. Among them, 904 (87.9%) reported a history of sexual activity. Only 36.6% reported condom use at last intercourse; those who did were more likely to report commercial sex work (odds ratio [OR] 9.01 [1.46-55.55]), to state that STI prevention was a primary reason for using condoms (OR = 6.84 [4.81-9.71]), to have been previously diagnosed with an STI (OR = 2.39 [1.36-4.21]), to report that 'it is easy to tell a sexual partner they will not have vaginal/anal sex without a condom' (OR = 2.30 [1.56-3.39]), to report that sexual intercourse is only risky when people have anal sex (OR = 1.98 [1.22-3.22]); and less likely to be married (OR = 0.65 [0.54-0.78]), and to find it difficult to use condom consistently in all sexual encounters (OR = 0.36 [0.25-0.52]). Women who reported condom use were more concerned with preventing STIs, and to report less difficulty insisting on condom use with partners.
本研究的目的是评估巴西维多利亚市年轻女性的避孕套使用情况及相关行为。2006年3月至12月，选取了18 - 29岁的女性作为基于人群的研究的横断面样本。对艾滋病毒和性传播感染（STIs）的风险行为进行了调查。将上次性交时使用避孕套作为描述保护性性行为的主要结果进行评估。在确定的1200名符合条件的女性中，1029名（85.8%）登记入组。其中，904名（87.9%）报告有性活动史。只有36.6%的人报告上次性交时使用了避孕套；使用避孕套的人更有可能报告从事商业性工作（优势比[OR] 9.01 [1.46 - 55.55]），称预防性传播感染是使用避孕套的主要原因（OR = 6.84 [4.81 - 9.71]），曾被诊断患有性传播感染（OR = 2.39 [1.36 - 4.21]），报告“很容易告诉性伴侣不使用避孕套就不会进行阴道/肛交”（OR = 2.30 [1.56 - 3.39]），报告只有在进行肛交时性交才有风险（OR = 1.98 [1.22 - 3.22]）；结婚的可能性较小（OR = 0.65 [0.54 - 0.78]），且发现在所有性接触中始终使用避孕套有困难（OR = 0.36 [0.25 - 0.52]）。报告使用避孕套的女性更关注预防性传播感染，且报告在坚持与伴侣使用避孕套方面困难较小。
