To examine factors associated with contraceptive choice among HIV-infected women.
Data for this cross-sectional analysis were derived from baseline visits of 435 participants in an ongoing prospective study of contraception among HIV-infected women in Russia. Participants enrolled in one of four groups: combined oral contraceptives (COCs) along with condoms, depot medroxyprogesterone acetate (DMPA) along with condoms, copper intrauterine device (IUD) along with condoms, or condoms alone.
After contraceptive counseling and assessment of medical eligibility to use study methods, participants selected a method. Standardized interviews were used to collect demographic, reproductive and behavioral information.
Most women were eligible to use COCs (89%) and DMPA (94%); 87% of nonpostpartum women were eligible to use the IUD. The method chosen by most women was condoms alone (47%), followed by COCs along with condoms (29%), DMPA along with condoms (20%) and IUD along with condoms (4%). In multivariable analyses, independent predictors of choosing a method highly effective during typical use (COCs, DMPA, or IUD) along with condoms included having at least two births (prevalence ratio = 1.4), postpartum enrollment (prevalence ratio = 1.3), desiring (prevalence ratio = 1.4), or uncertainty about desiring (prevalence ratio = 1.3) a future pregnancy, prior oral contraceptive use (prevalence ratio = 1.3), recent injection drug use (prevalence ratio = 1.3) and never (prevalence ratio = 2.3) or sometimes (prevalence ratio = 1.9) using condoms in the last year.
Among HIV-infected women, several characteristics that may place women at greater risk for unintended pregnancy and its adverse consequences were associated with choice of highly effective contraceptive methods. These findings may aid in the development of interventions to increase use of effective contraception among HIV-infected women.
探讨与 HIV 感染女性避孕方法选择相关的因素。
本横断面分析的数据来源于正在进行的俄罗斯 HIV 感染女性避孕方法前瞻性研究的 435 名参与者的基线访视。参与者分为四组之一:口服避孕药(COC)联合避孕套、醋酸甲羟孕酮长效避孕针(DMPA)联合避孕套、含铜宫内节育器(IUD)联合避孕套或单独使用避孕套。
在避孕咨询和评估使用研究方法的医学适宜性后,参与者选择一种方法。采用标准化访谈收集人口统计学、生殖和行为信息。
大多数女性有资格使用 COC(89%)和 DMPA(94%);87%的非产后妇女有资格使用 IUD。大多数女性选择的方法是单独使用避孕套(47%),其次是 COC 联合避孕套(29%)、DMPA 联合避孕套(20%)和 IUD 联合避孕套(4%)。多变量分析显示,选择高度有效的常规避孕方法(COC、DMPA 或 IUD)联合避孕套的独立预测因素包括至少生育两次(优势比=1.4)、产后入组(优势比=1.3)、希望(优势比=1.4)或对未来怀孕的不确定性(优势比=1.3)、之前使用口服避孕药(优势比=1.3)、近期注射吸毒(优势比=1.3)以及过去一年从不(优势比=2.3)或偶尔(优势比=1.9)使用避孕套。
在 HIV 感染女性中,一些可能增加意外怀孕及其不良后果风险的特征与高效避孕方法的选择有关。这些发现可能有助于制定干预措施,增加 HIV 感染女性对有效避孕方法的使用。
