The effect of immediate postpartum depot medroxyprogesterone on early breastfeeding cessation

Breastfeeding and Hormonal Contraception: A Scoping Review of Clinical Guidelines, Professional Association Recommendations, and the Literature

Background: Postpartum contraceptive use can help prevent short-interval pregnancies, which have been associated with adverse neonatal and maternal health outcomes. Many contraceptive methods are safe for postpartum use, but patients and providers may be confused as to what impact hormonal contraception has on lactation. We performed a scoping review of the most recent U.S.-based guidelines regarding hormonal contraception on lactation to provide synthesis and recommendations to aid providers in counseling their patients. Methods: We conducted a scoping review by identifying the most recent clinical recommendations and guidelines from the Centers for Disease Control and Prevention (CDC) and three maternal and child health professional associations (American College of Obstetricians and Gynecologists [ACOG], Society for Maternal-Fetal Medicine [SMFM], and Academy of Breastfeeding Medicine [ABM]). We also reviewed the citations in these guidelines used in their development. We then conducted an updated literature review to capture studies published since the most recent systematic reviews were conducted. Results: We reviewed 1 clinical guideline from the CDC and 2 systematic reviews cited in its references, 6 professional association recommendations, and 28 publications identified through the updated literature review. Progestin-only contraceptive methods continue to demonstrate safety in breastfeeding patients, while low-quality evidence supports concerns of decreased milk supply with combined hormonal contraception. Discussion: Organizations should consider updating counseling recommendations regarding progestin-only contraceptives and lactation. Further research is needed to examine new contraceptive methods as well as the effect of hormonal contraception on lactation in the setting of preterm birth.

Breastfeeding Perceptions and Behavior Among Postpartum Women Initiating Different Hormonally Systemic Contraceptive Methods

BACKGROUND

There continues to be controversy regarding the simultaneous encouragement of both breastfeeding and immediate postpartum contraception.

RESEARCH AIM

To explore postpartum women's perspectives about breastfeeding and their breastfeeding behaviors, while using one of three different hormonally systemic contraceptive methods immediately postpartum over a 6 month period of time.

METHODS

This was a retrospective, longitudinal, three group comparative, secondary analysis of a prospective cohort study (N = 471) of immediate postpartum contraception. Breastfeeding, for this study, was defined as providing any human milk to the infant. Participants who chose one of three different hormonally systemic forms of contraception immediately postpartum (a long-acting hormonal reversible contraceptive (n = 200), depot medroxyprogesterone acetate 150 mg (n = 98), or a non-hormonal method (n = 173)) were compared at hospital discharge, 6 weeks, 3 months, and 6 months postpartum. The primary outcome was any breastfeeding at 6 months. Secondary outcomes included any and exclusive breastfeeding, concerns about breastfeeding while using contraception, and reasons for breastfeeding discontinuation.

RESULTS

There was no significant difference in the rate of any breastfeeding between the two hormonal and the non-hormonal contraceptive groups at 6 months postpartum (long-acting hormonal 20.1%, non-hormonal 21.7%, depot medroxyprogesterone acetate 13.9%, p = .77, 0.28, respectively). The number of participants who reported stopping breastfeeding due to decreased milk supply was not significantly different between any groups at all time points (total number who discontinued at 6 months postpartum was long-acting hormonal 24.7%, non-hormonal 25.1%, depot medroxyprogesterone acetate 19.3%, p = .30).

CONCLUSIONS

Breastfeeding perspectives and behavioral outcomes over the first 6 months postpartum were not influenced by participants chosen form of immediate postpartum contraception.

Effect of Postpartum Depo Medroxyprogesterone Acetate on Lactation in Mothers of Very Low-Birth-Weight Infants

Objective: This study examined the effect of postpartum administration of depo medroxyprogesterone acetate (DMPA) on milk production, time to onset of secretory activation, lactation duration, and infant consumption of mother's own milk (MOM) in mothers of preterm very low-birth-weight (VLBW) infants. Materials and Methods: We conducted a secondary analysis of data from mothers who delivered infants weighing ≤1,500 g and at ≤32 weeks' gestation. The volume of milk produced was measured on days 1-7, 14, and 21 by weighing all expressed milk on an electronic scale. Time to secretory activation was determined through self-report of a feeling of breast fullness. Information on lactation duration and the percent of feeds consisting of MOM consumed by infants was obtained from the medical records. Results: Mothers who received postpartum DMPA were more likely to be African American (72.4% versus 31.4%; p = 0.0006), unemployed (65.5% versus 44.5%; p = 0.027), and Medicaid eligible (89.7% versus 67.2%; p = 0.019). There were no differences in daily milk production between mothers who received DMPA before hospital discharge (n = 29) compared with those who did not (n = 141). When mothers who reached secretory activation before receiving DMPA were removed from analysis, receiving DMPA was associated with a later onset of secretory activation (103.7 versus 88.6 hours; p = 0.028). There were no statistically significant differences between the study groups in lactation duration or infant MOM consumption. Conclusions: DMPA, when administered postpartum to mothers of preterm VLBW infants, delayed secretory activation, but had no detrimental effect on milk production or lactation duration. Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT01892085.

Priorities for Contraception and Lactation Among Breast Pump-Dependent Mothers of Premature Infants in the Neonatal Intensive Care Unit

Objective: Determine the knowledge and priorities for postpartum contraception and lactation in mothers of premature infants. Design: Twenty-five mothers of premature infants (mean gestational age = 29.9 weeks) hospitalized in a tertiary neonatal intensive care unit (NICU) participated in a multi-methods study using a multiple-choice contraceptive survey and qualitative interview in the first 2 weeks postpartum. Data were analyzed using content analysis and descriptive statistics. Results: Although 60% of mothers planned to use contraception, all questioned the timing of postpartum contraceptive counseling while recovering from a traumatic birth and coping with the critical health status of the infant. All mothers prioritized providing mothers' own milk (MOM) over the use of early hormonal contraception because they did not want to "take any risks" with their milk. They had limited knowledge of risks for repeat preterm birth (e.g., prior preterm birth: n = 13, 52%; multiple birth: n = 9, 36%; no knowledge: n = 3, 12%); only two mothers (0.08%) were counseled about the risks of a short interpregnancy interval. Conclusion: The context of the infants' NICU admission and the mother's desire to "do what is best for the baby" by prioritizing MOM should be integrated into postpartum contraceptive counseling for this population.

The Lactational Effects of Contraceptive Hormones: an Evaluation (LECHE) Study

OBJECTIVE

To estimate the proportion of women for whom use of hormonal contraception was associated with reporting a decreased breast milk supply.

STUDY DESIGN

The Lactational Effects of Contraceptive Hormones: an Evaluation ("LECHE") Study was an anonymous, internet-based, exploratory, cross-sectional survey of postpartum women using approximately 70 questions. Women were eligible to participate in the survey if they were 18 years or older, had a singleton infant between 3 and 9 months of age, had breastfed this infant for any amount of time and could read English. The survey included questions about breastfeeding, reproductive health, demographic characteristics and the timing of postpartum events.

RESULTS

A total of 3971 participants clicked on the survey. Our final study population included 2922 participants. Overall, 1201 (41%) reported having had milk supply concerns at some point in the first 12 weeks postpartum. The median time from birth until milk supply concerns was 3 weeks (IQR 1-7). Eight hundred fifty-two women (29%) started hormonal contraception in the first 12 weeks postpartum. Fifteen percent (127/852) of women reported new or additional milk supply concerns after starting hormonal contraception. Reported milk supply concerns were higher for women who used hormonal contraception than those who did not (44% vs. 40%; p=.05) Adjusted hazard ratios (HRs) assessing the association between contraceptive use and time to milk supply concerns were not statistically significant (HR 1.18, 95% confidence interval 0.94-1.47 for any type of hormonal contraception).

CONCLUSIONS

This study found a slightly increased proportion of reported milk supply concerns among women who started hormonal contraception.

IMPLICATIONS

It is important for caregivers in the postpartum period to recognize the potential for multiple factors, including initiation of hormonal contraception, to affect breastfeeding. Patient-centered counseling can help elicit women's values and preferences regarding breastfeeding and pregnancy prevention.

Optimizing maternal and neonatal outcomes with postpartum contraception: impact on breastfeeding and birth spacing

Postpartum contraception is important to prevent unintended pregnancies. Assisting women in achieving recommended inter-pregnancy intervals is a significant maternal-child health concern. Short inter-pregnancy intervals are associated with negative perinatal, neonatal, infant, and maternal health outcomes. More than 30% of women experience inter-pregnancy intervals of less than 18 months in the United States. Provision of any contraceptive method after giving birth is associated with improved inter-pregnancy intervals. However, concerns about the impact of hormonal contraceptives on breastfeeding and infant health have limited recommendations for such methods and have led to discrepant recommendations by organizations such as the World Health Organization and the U.S. Centers for Disease Control and Prevention. In this review, we discuss current recommendations for the use of hormonal contraception in the postpartum period. We also discuss details of the lactational amenorrhea method and effects of hormonal contraception on breastfeeding. Given the paucity of high quality evidence on the impact on hormonal contraception on breastfeeding outcomes, and the strong evidence for improved health outcomes with achievement of recommended birth spacing intervals, the real risk of unintended pregnancy and its consequences must not be neglected for fear of theoretical neonatal risks. Women should establish desired hormonal contraception before the risk of pregnancy resumes. With optimization of postpartum contraception provision, we will step closer toward a healthcare system with fewer unintended pregnancies and improved birth outcomes.

Association of Postpartum Predischarge Depot-Medroxyprogesterone Acetate with In-Hospital Breastfeeding Initiation

OBJECTIVE

The primary aim of this study was to examine the association between postpartum predischarge depot-medroxyprogesterone acetate (ppDMPA) and in-hospital breastfeeding initiation, and the secondary exploratory aim was to determine if any racial disparities are associated with ppDMPA receipt or its relationship to breastfeeding initiation.

MATERIALS AND METHODS

We conducted a cross-sectional retrospective chart review of maternal and newborn records at a large urban academic medical center. Variables extracted included in-hospital feeding choice, obstetrical and sociodemographic variables, infant characteristics, and ppDMPA receipt. The association of ppDMPA and maternal-child characteristics with breastfeeding initiation was examined using logistic regression analysis.

RESULTS

Among singleton live births of 919 mother-infant pairs (76.5% African American [AA]), 67% initiated breastfeeding (34% exclusive and 33% mixed) and 31.4% received ppDMPA. Breastfeeding rates differed significantly between AA (60.7%) and non-AA mothers (86.6%), and ppDMPA also differed significantly between AA (37.6%) and non-AA mothers (11.6%). Adjusting for other independent predictors, mothers who received ppDMPA were 1.5 times more likely not to initiate breastfeeding if AA, and 5.2 times more likely not to initiate breastfeeding if non-AA.

CONCLUSIONS

ppDMPA receipt was independently associated with decreased rates of breastfeeding initiation. Although more AA mothers received ppDMPA than non-AA, the association of ppDMPA with breastfeeding noninitiation was stronger in non-AA than in AA mothers. Future research should examine this question prospectively to ascertain if there is a cause-effect relationship and should address both physiological effects and social perceptions.

Lactation and contraception

PURPOSE OF REVIEW

This review examines evidence relevant to the effect of hormonal contraception on breastfeeding; and compares global and US recommendations for contraceptive initiation and use. Breastfeeding and use of postpartum contraception have high public health priority, making research in this area critical for optimizing guidance.

RECENT FINDINGS

High quality evidence remains limited with only a small number of well-conducted randomized controlled trials of hormonal methods and breastfeeding/neonatal growth outcomes. More evidence supports early initiation of progestin-only methods. Evidence on early initiation of combination hormonal methods is sparse.

SUMMARY

The WHO Medical Eligibility Criteria (MEC) differs from that of the US MEC. Generally, the WHO MEC is more restrictive, reflecting the potential greater impact on maternal child health if there is a negative impact from hormonal contraception on breastfeeding. Only well conducted clinical trials will further elucidate such an impact.

Postpartum contraception

As birth spacing has demonstrated health benefits for a woman and her children, contraception after childbirth is recognized as an important health issue. The potential risk of pregnancy soon after delivery underscores the importance of initiating postpartum contraception in a timely manner. The contraceptive method initiated in the postpartum period depends upon a number of factors including medical history, anatomic and hormonal factors, patient preference, and whether or not the woman is breastfeeding. When electing a contraceptive method, informed choice is paramount. The availability of long-acting reversible contraceptive methods immediately postpartum provides a strategy to achieve reductions in unintended pregnancy.

Prenatal contraceptive counseling and method provision after childbirth

Postpartum contraception is undergoing major changes, not only in timing, but also in content. Failure to provide immediate postpartum contraception contributes to the problems of unintended pregnancies and rapid repeat pregnancy because often the highest-risk women do not return for postpartum care. If they do attend that visit, they have often lost the insurance coverage that would enable them to use the most effective forms of birth control. Most of the issues surrounding early initiation of progestin-only methods and breastfeeding have been favorably resolved. In some cases, insurance coverage for delivery has been expanded to cover the costs of providing intrauterine devices and implants before the woman is discharged home. All of these new opportunities shift the burden of counseling about postpartum contraception onto the shoulders of the prenatal care provider. This article provides information about the advantages and disadvantages of providing immediate postpartum contraception with each of the eligible methods so clinicians can provide the needed counseling both during pregnancy and during hospitalization for delivery. It also provides guidance for initiation of bridging contraception, if needed, to initiate a method for a woman later in the postpartum period.

The discordance between planned use and actual receipt of immediate postpartum depot medroxyprogesterone among low-income women

BACKGROUND

This study describes the patterns of planned use and actual receipt of immediate postpartum depot medroxyprogesterone (DMPA) prior to hospital discharge among low-income breastfeeding initiators.

MATERIALS AND METHODS

Bivariate analyses among DMPA recipients by prenatal planned/unplanned use and the sensitivity of DMPA self-report relative to pharmacologic record were calculated.

RESULTS

Among immediate postpartum DMPA recipients (n=58), 72.4% (n=42) did not plan to use DMPA. The sensitivity of self-reported DMPA use was 89.7% (95% confidence interval, 85.2, 94.2).

CONCLUSIONS

Clinically, it is unclear if the immediate postpartum period is the appropriate time to obtain consent and administer a long-acting contraceptive method. In our sample, women accurately recalled receiving DMPA in the immediate postpartum period. However, the majority did not plan to use this contraceptive method. Further high-quality qualitative and quantitative research regarding women's contraceptive plans and perception of the postpartum DMPA consent process and the healthcare provider's attitudes regarding consent and prescription of immediate postpartum DMPA are warranted.

Patterns of postpartum depot medroxyprogesterone administration among low-income mothers

BACKGROUND

Depot medroxyprogesterone acetate (DMPA) is often administered immediately postpartum to reduce the risk of short-interval repeat or unintended pregnancies, but little is known about the actual patterns of postpartum DMPA use. This article examines the patterns of DMPA administered among low-income new mothers in an upstate New York State community.

METHODS

Mothers attending urban pediatric practices (births 2009-2011) completed a mailed survey approximately 5 months after delivery. Among 83 survey items were questions about breastfeeding and timing of DMPA receipt.

RESULTS

Unintended pregnancy was reported by 48.8% of the subjects. Their deliveries occurred across four local hospitals. Among the 31.3% of subjects who received postpartum DMPA, 62.6% received it prior to hospital discharge. Those receiving in-hospital DMPA (n=127) were significantly more likely than other mothers to be black, older, urban dwelling, non-high school graduates, multiparous, and planning to formula feed. Administration patterns differed by hospital.

CONCLUSIONS

This study of postpartum DMPA administration among a convenience sample of low-income mothers demonstrated rates of 26% overall, but there was between-hospital variability. Additional study may identify approaches to ensure timely administration to appropriate candidates.
