Desire to avoid pregnancy and contraceptive use among female methadone patients in Los Angeles.

Objective: Opioid use disorder (OUD) is increasing among U.S. women. Research indicates higher levels of unintended pregnancy among women with OUD as compared to the general population. Following formative in-depth research documenting the complexity of considerations around pregnancy in this population, we collected information on pregnancy preferences and contraceptive use among women attending methadone treatment.

Study Design: We surveyed women attending methadone clinics in Los Angeles in 2018. We used the Desire to Avoid Pregnancy (DAP) Scale, a 14-item instrument (0-4; 4 = highest desire to avoid pregnancy) to capture pregnancy preferences across 3 domains: cognitive desires, affective feelings, and anticipated consequences. We conducted factor analysis, descriptive analyses, and linear and logistic regressions to assess the DAP scale and to examine relationships between pregnancy preferences, sociodemographic characteristics, and contraceptive use.

Results: Women (n = 46) expressed the full range of pregnancy preferences (DAP score range: 0.4-4.0; mean: 2.24, standard deviation: 1.02; Cronbach's α = 0.92). Overall, 40% used contraception at last sex. Women who reported a greater preference to avoid pregnancy were marginally more likely to use contraception at last sex as compared to women who were more open to pregnancy (odds ratio = 1.73; p = 0.09).

Conclusions: Similar to findings from other populations, responses to the Desire to Avoid Pregnancy scale among a sample of women with OUD revealed a broad range of pregnancy preferences. Pregnancy preferences were marginally associated with contraceptive use in this sample suggesting that the DAP may provide useful insights on pregnancy preferences that may facilitate contraceptive and preconception counseling in this population.

Implications: Given the complexity of considerations around pregnancy for women with opioid use disorder, the DAP scale may be a valuable tool to identify women's pregnancy and childbearing preferences and to facilitate alignment of women's sexual and reproductive health desires with appropriate services.
