Data on the risk of death associated with various contraceptive methods are incomplete. Therefore, we analyzed the mortality rates for young, black inner-city women who used one of four methods of contraception--oral contraceptives, depomedroxyprogesterone acetate, intrauterine (contraceptive) devices, and barrier methods. The subjects were 30,580 15- to 44-year-old women who enrolled at a family planning clinic between 1967 and 1972 and who were observed by monitoring death certificates through the end of 1977. Forty percent of the 218 deaths observed were from accidents and violence. Use of this family planning clinic greatly reduced the risk of death from childbearing; only two deaths were associated with pregnancy and childbirth, compared with the 24 deaths expected. Overall, users of the four methods died at similar, low rates. Given that this study involves considerable loss to follow-up, possible acute effects of contraceptives (eg, infections or thrombosis) are more accurately estimated than possible long-term effects (eg, cancer).
与各种避孕方法相关的死亡风险数据并不完整。因此,我们分析了年轻的黑人城市中心女性采用四种避孕方法(口服避孕药、醋酸甲羟孕酮、宫内节育器和屏障法)之一后的死亡率。研究对象为1967年至1972年间在一家计划生育诊所登记的30580名15至44岁的女性,通过监测死亡证明对她们进行观察,直至1977年底。在观察到的218例死亡中,40%死于意外事故和暴力。利用这家计划生育诊所大大降低了生育带来的死亡风险;与预期的24例死亡相比,只有两例死亡与妊娠和分娩相关。总体而言,这四种方法的使用者死亡率相近且较低。鉴于这项研究存在大量失访情况,与避孕药具可能产生的长期影响(如癌症)相比,其可能产生的急性影响(如感染或血栓形成)能得到更准确的估计。
