Psychosocial Factors Associated With Postpartum Contraceptive Method Use After an Unintended Birth.

OBJECTIVE: To examine whether depression, intimate partner violence, and other psychosocial stressors were independently associated with effectiveness level of postpartum contraception among women who recently had an unintended birth. METHODS: We analyzed cross-sectional data from PRAMS (the Pregnancy Risk Assessment Monitoring System) to identify women who had an unintended birth between 2012 and 2015. The effectiveness level of the contraceptive method was coded into one of five categories based on the postpartum contraceptive method that women were using: none, less effective (withdrawal, rhythm, condoms, or other barrier), moderately effective (pill, patch, ring, or shot), long-acting reversible contraception (LARC; intrauterine devices or implants), and sterilization (female or male sterilization). Multinomial logistic regression was used to examine whether prepregnancy depression or elevated postpartum depressive symptoms, intimate partner violence before or during pregnancy, and number of psychosocial stressors before birth were associated with effectiveness level of method (compared with no method), in models adjusted for sociodemographics, pregnancy context, and postpartum context. RESULTS: Complete data were available for 56,445 (88.2%) of the 64,030 eligible women: 24.2% experienced depression; 5.3% experienced intimate partner violence; and 16.8% experienced five or more psychosocial stressors around the time of pregnancy or birth. In adjusted models, experiencing intimate partner violence and more stressors lowered women's relative risk of using sterilization, LARC, moderately effective methods, and less-effective contraceptive methods relative to no method use. Only prepregnancy depression was associated with using sterilization compared with no method use. CONCLUSIONS: Experiencing intimate partner violence and having more psychosocial stressors were each independently associated with not using a postpartum contraceptive method. Standardized screening for psychosocial factors during prenatal and postpartum care should be integrated, and practices that encourage the discussion of patients' psychosocial experiences and postpartum contraception use together are warranted.

Intentionally or Ambivalently Risking a Short Interpregnancy Interval: Reproductive-Readiness Factors in Women's Postpartum Non-Use of Contraception.

A focus of research on short interpregnancy intervals (IPI) has been on young disadvantaged women whose births are likely to be unintended. Later initiation of family formation in the United States and other high-income countries points to the need to also consider a woman's attributes indicative of readiness for purposefully accelerated family formation achieved through short IPIs. We test for whether factors indicating "reproductive readiness"-including being married, being older, and having just had a first birth or a birth later than desired-predict a woman's non-use of contraception in the postpartum months. We also test for whether this contraceptive non-use results explicitly from wanting to become pregnant again. The data come from the 2012-2015 Pregnancy Risk Assessment Monitoring System, representing women who recently gave birth in any of 35 U.S. states and New York City (N = 120,111). We find that these reproductive-readiness factors are highly predictive of women's postpartum non-use of contraception because of a stated desire to become pregnant and are moderately predictive of contraceptive non-use without an explicit pregnancy intention. We conclude that planning for, or ambivalently risking, a short IPI is a frequent family-formation strategy for women whose family formation has been delayed. This is likely to become increasingly common as family formation in the United States is initiated later in the reproductive life course.
