背景本横断面研究估计避孕方法的流行率，并调查是否堕胎率影响避孕行为之间的注射吸毒（IDU）妇女在圣彼得堡，Russia.Methodology一个自我管理的问卷调查的行为在过去3个月被应用到一个方便的样本IDU women.Results的80个性活跃的参与者，67%有流产。没有参与者报告使用激素避孕药或宫内节育器（IUD）。使用的唯一有效避孕方法是避孕套，一半的参与者报告了这一点。22%的参与者报告了持续使用避孕套的情况，在堕胎的人中也没有更大的可能性。避孕套的使用与有多个性伴侣或临时性伴侣显著相关[患病率（PR）1.75，95%]。（置信区间）CI 1.11-2.78，p = 0.01]，有IDU性伴侣（PR 0.55，95%CI 0.36-0.85，p = 0.029）和对安全套持否定态度（PR 0.53，95%CI 0.33-0.84，p = 0.01）。流产是不太可能在那些谁有多个或临时性伴侣（PR 0.69，95%CI 0.49-0.97，p = 0.03）。结论尽管高流行率的流产注射吸毒妇女，没有报告使用激素避孕药或宫内节育器。堕胎与使用避孕套的可能性增加无关。参与者大多与临时或多个性伴侣使用安全套，这表明安全套主要用于预防艾滋病毒/性传播感染传播，而不是预防怀孕。需要在这一未得到充分研究的弱势群体中制定预防意外怀孕和减少堕胎相关健康风险的方案。
Background This cross-sectional study estimated the prevalence of contraceptive methods and investigated whether abortion rates influence contraceptive behaviour among injection drug-using (IDU) women in St Petersburg, Russia.Methodology A self-administered questionnaire of behaviour in the last 3 months was applied to a convenient sample of IDU women.Results Of 80 sexually active participants, 67% had had an abortion. No participant reported using hormonal contraceptives or intrauterine devices (IUDs). The only valid method of contraception used was condoms, which was reported by half of the participants. Consistent condom use was reported by 22% of participants and was no more likely among those who had an abortion. Condom use was significantly associated with having multiple or casual sex partners [prevalence ratio (PR) 1.75, 95% (confidence interval) CI 1.11-2.78, p = 0.01], having an IDU sex partner (PR 0.55, 95% CI 0.36-0.85, p = 0.029) and with a negative attitude toward condoms (PR 0.53, 95% CI 0.33-0.84, p = 0.01). Abortions were less likely among those who had multiple or casual sex partners (PR 0.69, 95% CI 0.49-0.97, p = 0.03).Conclusions Despite the high prevalence of abortions among IDU women, none reported the use of hormonal contraception or IUDs. Having had an abortion was not associated with greater likelihood of using condoms. Participants mostly used condoms with casual or multiple sex partners, suggesting that condoms were used mainly to prevent HIV/sexually transmitted infection transmission and not to prevent pregnancy. Programmes to prevent unwanted pregnancies and reduce abortion-related health risks among this understudied vulnerable group are needed.
