ABM Clinical Protocol #13: Contraception During Breastfeeding, Revised 2015

Sustainable Breastfeeding: A State-of-the Art Review

BACKGROUND

Disparities in breastfeeding rates and exclusivity exist across regions and countries despite multifaceted breastfeeding promotion efforts in recent decades. Markets for artificial milk formula continue to grow as its substitution for breastfeeding is common. A new approach is needed for breastfeeding promotion strategies.

RESEARCH AIM

This state-of-the-art review aimed to describe the implications of not-breastfeeding on the environment within the context of food system sustainability.

METHOD

A total of 19 peer-reviewed articles within a 20-year timeframe were included in this review. Authors searched five databases for articles including Science Direct, GreenFILE, Springer Link, ProQuest, and PubMed.

RESULTS

The demand for artificial milk formula production as a replacement for breastfeeding results in increased greenhouse gas emissions, water pollution, and waste, thereby aggravating problems with freshwater scarcity. A short duration of breastfeeding and limited exclusivity have been associated with close birth spacing and contributing to global population growth. Breastfeeding is a healthy, sustainable diet, and a culturally acceptable first food. It advances health equity and food security. Exclusive breastfeeding for the first 6 months of life can be promoted with emphasis on total carbon footprint reduction, prevention of waterway degradation, and natural birth spacing, thereby sustaining food systems at large.

CONCLUSION

It is important to reform food, nutrition, and environmental policies to protect exclusive breastfeeding while decarbonizing artificial milk formula production. More research is needed to provide directions for new breastfeeding promotion strategies connecting breastfeeding with environmental stewardship.

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.

Understanding of Lactational Amenorrhea As a Contraceptive Method Among U.S. Pregnant Women

Introduction: The lactational amenorrhea method (LAM) of postpartum contraception is more effective than typical use of condoms or birth control pills. However, LAM may be underutilized due to incomplete perinatal counseling. Methods: We compared perceptions of the effectiveness of postpartum contraceptives including LAM among U.S.-born nulliparous pregnant women recruited using social media for a trial (NCT04601987). We used descriptive statistics to summarize data. Results: Of 760 individuals screened, 627 were invited to participate, and 451 (72%) were enrolled. Most (81%) had a college degree; 79% intended to breastfeed for at least 1 month. Only 8% believed exclusive breastfeeding reduces the chance of pregnancy "a lot" within 6 months of delivery and 2% indicated that exclusive breastfeeding is typically more effective than birth control pills or condoms. Compared with those planning to use other postpartum contraceptives, the 17% of respondents who planned to use LAM were more likely to know that breastfeeding delays return of menses (84% versus 44%, p ≤ 0.0001) and provides protection from pregnancy until menses return (54% versus 22%, p ≤ 0.0001). Although 25% of those planning to use LAM believed exclusive breastfeeding reduces pregnancy risk by "a lot," only 5% thought LAM is more effective than birth control pills and only 9% thought that it is more effective than condoms. Conclusions/Implications: First-time U.S. mothers are often unaware of breastfeeding's effects on menses and fertility. Clinicians providing counseling about postpartum contraceptive options should include more information on LAM.

Infant feeding for people living with HIV in high resource settings: a multi-disciplinary approach with best practices to maximise risk reduction

Shared decision making for infant feeding in the context of HIV in high-resourced settings is necessary to acknowledge patient autonomy, meet increasing patient requests and address the changing reality of perinatal HIV care. In low-to middle-income countries (LMIC), where the majority of individuals living with HIV reside, persons with HIV are recommended to breastfeed their infants. In the setting of maternal anti-retroviral therapy (ART) use throughout pregnancy, viral suppression and appropriate neonatal post-exposure prophylaxis (PEP) use, updated information indicates that the risk of HIV transmission through breastmilk may be between 0.3 and 1%. While not endorsing or recommending breastfeeding, the United States' DHHS perinatal guidelines are similarly pivoting, stating that individuals should "receive patient-centred, evidence-based counselling on infant feeding options." Similar statements appear in the British, Canadian, Swiss, European, and Australasian perinatal guidelines. We assembled a multi-disciplinary group at our institution to develop a structured shared decision-making process and protocol for successful implementation of breastfeeding. We recommend early and frequent counselling about infant feeding options, which should include well known benefits of breastfeeding even in the context of HIV and the individual's medical and psychosocial circumstances, with respect and support for patient's autonomy in choosing their infant feeding option.

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.

Evaluating Shared Decision-Making in Postpartum Contraceptive Counseling Using Objective Structured Clinical Examinations

BACKGROUND

Shared decision-making (SDM) may support widespread uptake of progestin-containing long-acting reversible contraceptives in the immediate postpartum period. We piloted an Objective Structured Clinical Examination (OSCE) to evaluate first-year obstetrics and gynecology resident physicians' use of SDM in postpartum contraception counseling.

METHODS

As part of their 2015 and 2016 OSCEs, first-year OB/GYN residents were instructed to provide contraceptive counseling to a Standardized Patient (SP) portraying a 29-year-old postpartum patient seen during rounds on the morning following her delivery. Three investigators independently scored each resident encounter using a 10-item rubric adapted from a 9-item SDM measure and assigned scores of 0 (absent), 1 (partial), or 2 (complete). Each encounter was video and audio recorded, then transcribed for qualitative analysis. Descriptive statistics was produced using SPSS version 24.

RESULTS

Eighteen residents participated. The majority (78%) discussed contraceptive options and timing of initiation. Nearly 33% elicited factors most important to the SP in influencing her preference. Only 6% discussed the benefits of exclusive breastfeeding, and few addressed the uncertainty of progesterone on milk supply and production.

CONCLUSION

Although residents conveyed ample clinical information, the vast majority did not discuss elements of SDM, such as her preferences, values, and goals for future fertility and breastfeeding. Our work revealed that critical elements of SDM are often not explored and deliberated by resident physicians. Trainings (e.g., OSCEs) are needed to equip residents with effective communication skills to facilitate more SDM in postpartum contraceptive care.

Future Pregnancy Considerations after Premature Birth of an Infant Requiring Intensive Care: A Qualitative Study

BACKGROUND

Postpartum contraception counseling and method use vary widely among patients who had a preterm birth. We performed this study to explore what issues and concerns individuals with preterm infants requiring intensive care describe as influencing their postpartum contraceptive choices.

METHODS

We conducted a qualitative study using semi-structured interviews with participants who gave birth to a singleton preterm infant admitted to the neonatal intensive care unit (NICU). We explored pregnancy, childbirth, postpartum care, and NICU experiences, as well as future reproductive plans and postpartum contraceptive choices. Two coders used a constant-comparative approach to code transcripts and identify themes.

RESULTS

We interviewed 26 participants: 4 (15%) gave birth at less than 26, 6 (23%) at 26 to 27 6/7, 8 (31%) at 28 to 31 6/7, and 8 (31%) at 32 to 36 6/7 weeks of gestation. We identified three main themes related to future pregnancy plans and contraception choice. First, participants frequently described their preterm birth and their infants' NICU hospitalization as traumatic experiences that affected plans for future pregnancies. The loss of control in predicting or preventing a future preterm birth and uncertainty about their premature child's future medical needs resulted in participants wanting to avoid going through the same experience with another child. Second, participants chose contraception based on previous personal experiences, desired method features, and advice from others. Last, having a preterm birth did not result in any ambivalence among those who desired permanent contraception.

CONCLUSIONS

Preterm birth influences future pregnancy plans. When discussing reproductive goals with patients, clinicians should be aware of potential trauma associated with a premature birth, assess for whether patients want to discuss contraception, and center the conversation around individual needs if patients do desire contraceptive counseling.

Effectiveness of Fertility Awareness-Based Methods for Pregnancy Prevention During the Postpartum Period

OBJECTIVES

To summarize the evidence on typical and perfect-use effectiveness of fertility awareness-based methods for avoiding pregnancy during the postpartum period, whether breastfeeding or not.

STUDY

Design We conducted a systematic review of studies published in English, Spanish, French, or German by November 2021 in MEDLINE, EMBASE, CINAHL, Web of Science, and ClinicalTrials.gov. Abstract and full text review were completed by two independent reviewers. Study inclusion: at least 50 subjects who enrolled prior to experiencing three cycles after childbirth and were using a specific fertility awareness-based method to avoid pregnancy; unintended pregnancy rate or probability calculated; postpartum amenorrheic and postpartum cycling individuals analyzed separately; and prospectively measured pregnancy intentions and outcomes. Outcomes were abstracted and study quality was systematically assessed by two independent investigators.

RESULTS

Four studies provided effectiveness data for one specific fertility awareness-based method among postpartum individuals. Of these, there were zero high quality, one moderate quality, and three low quality for our question of interest. Typical-use pregnancy probability for the first six cycles postpartum for Marquette Method users was 12.0 per 100 women years (standard error [SE] not reported) and for Billings Ovulation Method users ranged from 9.1 (SE 3.9) for non-lactating women <30 years old to 26.8 (SE 4.6) for lactating women <30 years old. Typical-use pregnancy probabilities for the first six months post-first menses for the Postpartum Bridge to Standard Days Method users was 11.8 (95% confidence interval 6.01-17.16) and for Billings Ovulation Method users was 8.5 per 100 women (SE 1.7).

CONCLUSIONS

The current evidence on the effectiveness of each fertility awareness-based method for postpartum persons is very limited and of mostly low quality. More high quality studies on the effectiveness of fertility awareness-based method in postpartum persons are needed to inform clinical counseling and patient-centered decision-making.

Impact of Group Prenatal Care on Contraceptive Use at Twelve Weeks Postpartum

OBJECTIVES

To compare the prevalence of highly effective contraceptive use by 12 weeks postpartum among participants of Centering Pregnancy®, a model of group prenatal care (GPC), and traditional prenatal care (TPC), and to investigate differences in contraceptive method choice by type of prenatal care.

METHODS

We performed a retrospective review of all eligible patients who participated in GPC (n = 143) and a random sample of patients participating in TPC (n = 290) who followed up at our institution within 12 weeks of delivery. Our primary outcome was the proportion of participants using a highly effective contraceptive method within 12 weeks postpartum. Contraceptives were classified in tiers (Tier 1, long-acting reversible and permanent contraception; Tier 2, oral contraceptive pills, transdermal patch, vaginal ring, or injection; Tier 3, barrier and fertility awareness methods, withdrawal, spermicide; and no method). Tier 1 and Tier 2 methods were considered highly effective.

RESULTS

The prevalence of highly effective contraceptive use by 12 weeks postpartum was 63.6% (91 of 143) and 63.1% (183 of 290) among participants in GPC and TPC, respectively (p = 0.99). We found no difference in Tier 1 versus other method use (adjusted odds ratio (aOR) 1.05, 95% CI 0.95-1.15, p = 0.34) or Tier 2 versus other method use between groups (aOR 0.98, 95% CI 0.89-1.08, p = 0.69), in a multivariable model controlling for demographic and clinical factors.

CONCLUSIONS FOR PRACTICE

The prevalence of highly effective contraceptive use at 12 weeks postpartum was not different between GPC and TPC participants in this study. GPC was not associated with increased use of Tier 1 or Tier 2 contraceptive methods.

Lactational Amenorrhea: Neuroendocrine Pathways Controlling Fertility and Bone Turnover

Lactation is a physiological state of hyperprolactinemia and associated amenorrhea. Despite the fact that exact mechanisms standing behind the hypothalamus-pituitary-ovarian axis during lactation are still not clear, a general overview of events leading to amenorrhea may be suggested. Suckling remains the most important stimulus maintaining suppressive effect on ovaries after pregnancy. Breastfeeding is accompanied by high levels of prolactin, which remain higher than normal until the frequency and duration of daily suckling decreases and allows normal menstrual function resumption. Hyperprolactinemia induces the suppression of hypothalamic Kiss1 neurons that directly control the pulsatile release of GnRH. Disruption in the pulsatile manner of GnRH secretion results in a strongly decreased frequency of corresponding LH pulses. Inadequate LH secretion and lack of pre-ovulatory surge inhibit the progression of the follicular phase of a menstrual cycle and result in anovulation and amenorrhea. The main consequences of lactational amenorrhea are connected with fertility issues and increased bone turnover. Provided the fulfillment of all the established conditions of its use, the lactational amenorrhea method (LAM) efficiently protects against pregnancy. Because of its accessibility and lack of additional associated costs, LAM might be especially beneficial in low-income, developing countries, where modern contraception is hard to obtain. Breastfeeding alone is not equal to the LAM method, and therefore, it is not enough to successfully protect against conception. That is why LAM promotion should primarily focus on conditions under which its use is safe and effective. More studies on larger study groups should be conducted to determine and confirm the impact of behavioral factors, like suckling parameters, on the LAM efficacy. Lactational bone loss is a physiologic mechanism that enables providing a sufficient amount of calcium to the newborn. Despite the decline in bone mass during breastfeeding, it rebuilds after weaning and is not associated with a postmenopausal decrease in BMD and osteoporosis risk. Therefore, it should be a matter of concern only for lactating women with additional risk factors or with low BMD before pregnancy. The review summarizes the effect that breastfeeding exerts on the hypothalamus-pituitary axis as well as fertility and bone turnover aspects of lactational amenorrhea. We discuss the possibility of the use of lactation as contraception, along with this method's prevalence, efficacy, and influencing factors. We also review the literature on the topic of lactational bone loss: its mechanism, severity, and persistence throughout life.

Strategies to increase the use of mother's own milk for infants at risk of necrotizing enterocolitis

High-dose mother's own milk (MOM) feedings during the first 14 days post birth reduce the risk of necrotizing enterocolitis in very low birthweight (VLBW; <1500 g birthweight). However, high-dose MOM feedings are only possible if mothers provide sufficient quantities of MOM in a timely manner, and data indicate that the lack of MOM during the early post-birth period is a global problem. This paper reviews the modifiable and unmodifiable barriers to accessing adequate quantities of MOM during the early post-birth period and proposes evidence-based strategies to increase and improve the use of MOM during the neonatal intensive care unit (NICU) hospitalization with an emphasis on the critical first 2 weeks post birth.

Oral galactagogues (natural therapies or drugs) for increasing breast milk production in mothers of non-hospitalised term infants

BACKGROUND

Many women express concern about their ability to produce enough milk, and insufficient milk is frequently cited as the reason for supplementation and early termination of breastfeeding. When addressing this concern, it is important first to consider the influence of maternal and neonatal health, infant suck, proper latch, and feeding frequency on milk production, and that steps be taken to correct or compensate for any contributing issues. Oral galactagogues are substances that stimulate milk production. They may be pharmacological or non-pharmacological (natural). Natural galactagogues are usually botanical or other food agents. The choice between pharmacological or natural galactagogues is often influenced by familiarity and local customs. Evidence for the possible benefits and harms of galactagogues is important for making an informed decision on their use.

OBJECTIVES

To assess the effect of oral galactagogues for increasing milk production in non-hospitalised breastfeeding mother-term infant pairs.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Health Research and Development Network - Phillippines (HERDIN), Natural Products Alert (Napralert), the personal reference collection of author LM, and reference lists of retrieved studies (4 November 2019).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) comparing oral galactagogues with placebo, no treatment, or another oral galactagogue in mothers breastfeeding healthy term infants. We also included cluster-randomised trials but excluded cross-over trials.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane Pregnancy and Childbirth methods for data collection and analysis. Two to four review authors independently selected the studies, assessed the risk of bias, extracted data for analysis and checked accuracy. Where necessary, we contacted the study authors for clarification.

MAIN RESULTS

Forty-one RCTs involving 3005 mothers and 3006 infants from at least 17 countries met the inclusion criteria. Studies were conducted either in hospitals immediately postpartum or in the community. There was considerable variation in mothers, particularly in parity and whether or not they had lactation insufficiency. Infants' ages at commencement of the studies ranged from newborn to 6 months. The overall certainty of evidence was low to very low because of high risk of biases (mainly due to lack of blinding), substantial clinical and statistical heterogeneity, and imprecision of measurements. Pharmacological galactagogues Nine studies compared a pharmacological galactagogue (domperidone, metoclopramide, sulpiride, thyrotropin-releasing hormone) with placebo or no treatment. The primary outcome of proportion of mothers who continued breastfeeding at 3, 4 and 6 months was not reported. Only one study (metoclopramide) reported on the outcome of infant weight, finding little or no difference (mean difference (MD) 23.0 grams, 95% confidence interval (CI) -47.71 to 93.71; 1 study, 20 participants; low-certainty evidence). Three studies (metoclopramide, domperidone, sulpiride) reported on milk volume, finding pharmacological galactagogues may increase milk volume (MD 63.82 mL, 95% CI 25.91 to 101.72; I² = 34%; 3 studies, 151 participants; low-certainty evidence). Subgroup analysis indicates there may be increased milk volume with each drug, but with varying CIs. There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints, such as tiredness, nausea, headache and dry mouth (very low-certainty evidence). No adverse effects were reported for infants. Natural galactagogues Twenty-seven studies compared natural oral galactagogues (banana flower, fennel, fenugreek, ginger, ixbut, levant cotton, moringa, palm dates, pork knuckle, shatavari, silymarin, torbangun leaves or other natural mixtures) with placebo or no treatment. One study (Mother's Milk Tea) reported breastfeeding rates at six months with a concluding statement of "no significant difference" (no data and no measure of significance provided, 60 participants, very low-certainty evidence). Three studies (fennel, fenugreek, moringa, mixed botanical tea) reported infant weight but could not be meta-analysed due to substantial clinical and statistical heterogeneity (I² = 60%, 275 participants, very low-certainty evidence). Subgroup analysis shows we are very uncertain whether fennel or fenugreek improves infant weight, whereas moringa and mixed botanical tea may increase infant weight compared to placebo. Thirteen studies (Bu Xue Sheng Ru, Chanbao, Cui Ru, banana flower, fenugreek, ginger, moringa, fenugreek, ginger and turmeric mix, ixbut, mixed botanical tea, Sheng Ru He Ji, silymarin, Xian Tong Ru, palm dates; 962 participants) reported on milk volume, but meta-analysis was not possible due to substantial heterogeneity (I² = 99%). The subgroup analysis for each intervention suggested either benefit or little or no difference (very low-certainty evidence). There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints such as mothers with urine that smelled like maple syrup and urticaria in infants (very low-certainty evidence). Galactagogue versus galactagogue Eight studies (Chanbao; Bue Xue Sheng Ru, domperidone, moringa, fenugreek, palm dates, torbangun, moloco, Mu Er Wu You, Kun Yuan Tong Ru) compared one oral galactagogue with another. We were unable to perform meta-analysis because there was only one small study for each match-up, so we do not know if one galactagogue is better than another for any outcome.

AUTHORS' CONCLUSIONS

Due to extremely limited, very low certainty evidence, we do not know whether galactagogues have any effect on proportion of mothers who continued breastfeeding at 3, 4 and 6 months. There is low-certainty evidence that pharmacological galactagogues may increase milk volume. There is some evidence from subgroup analyses that natural galactagogues may benefit infant weight and milk volume in mothers with healthy, term infants, but due to substantial heterogeneity of the studies, imprecision of measurements and incomplete reporting, we are very uncertain about the magnitude of the effect. We are also uncertain if one galactagogue performs better than another. With limited data on adverse effects, we are uncertain if there are any concerning adverse effects with any particular galactagogue; those reported were minor complaints. High-quality RCTs on the efficacy and safety of galactagogues are urgently needed. A set of core outcomes to standardise infant weight and milk volume measurement is also needed, as well as a strong basis for the dose and dosage form used.

Modern contraceptive use and factors associated with use among postpartum women in Ethiopia; further analysis of the 2016 Ethiopia demographic and health survey data

Background

The postpartum period is a critical time to improve maternal and child health. It is a time for accessing contraceptives to prevent short inter-pregnancy intervals. More than 95% of postpartum women do not want to get pregnant within 12 months. However, many women in Ethiopia experience an unintended pregnancy, and there is low information about postpartum contraceptive use among women who have family planning demand. Therefore, this study aimed to estimate the prevalence of postpartum contraceptive use and its predictors among women who give birth 12 months before the survey in Ethiopia.

Methods

We used the 2016 Ethiopia demographic health survey data for this analysis. The survey was a community-based cross-sectional study conducted from January 18 to June 27, 2016. The survey employed a two-stage stratified cluster sampling technique. A total of 2304 postpartum women were included. Bivariate and multivariable logistics regressions were done to identify factors associated with postpartum contraceptive use. A p-value < 0.05 was used to declare statistical significance.

Results

About 23.7% (23.7, 95% CI: 20.7–27.0%) of postpartum women were using modern contraceptives. Women who were urban residents (AOR = 2.18; 95%CI: 1.34–3.55), those who attended secondary or higher education (AOR = 1.79; 95%CI: 1.04–3.10), women who attended 1–3 (AOR = 2.33; 95%CI:1.27–4.25) or 4 or more ANC visits (AOR = 2.59; 95%CI:1.43–4.69) and women who delivered at a health facility (AOR = 1.86; 95%CI: 1.23–2.81) had higher odds of modern contraceptive use during the postpartum period. Similarly, women who reported the last child was no more wanted (AOR = 1.83; 95%CI: 1.01–3.31), women who decided for contraceptive use (AOR = 2.03; 95%CI: 1.13–3.65) and women whose recent child was male (AOR = 1.38; 95%CI: 1.01–1.88) had higher odds of modern contraceptive use.

Conclusion

Postpartum contraceptive use was low in Ethiopia. Strengthening health facility delivery, promoting girls’ education and encouraging women’s participation in deciding for contraceptive use would improve the uptake of modern contraceptives use during the postpartum period.

ABM Clinical Protocol #32: Management of Hyperlactation

A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breast-feeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

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.

Pharmacologic Management of Common Ailments in Women Who Are Breastfeeding

According to the Centers for Disease Control and Prevention, the rate of breastfeeding in the United States has increased 34% between 2005 and 2015. Women who breastfeed can require treatment of various common illnesses. When caring for women who are breastfeeding, health care providers may unnecessarily discourage them from breastfeeding during treatment. Choosing the appropriate medications for these individuals is critical to ensure the woman is effectively treated, infant exposure to medication is minimized, and the breastfeeding relationship is preserved. This article provides an overview of essential principles for prescribing medications for women who are lactating. Recommendations for the management of common illnesses seen in the outpatient setting are suggested and resources that can help guide therapeutic decision making are offered.

Placement of Levonorgestrel Intrauterine Device at the Time of Cesarean Delivery and the Effect on Breastfeeding Duration

Objectives: Studies have shown that immediate postpartum initiation of long-acting reversible contraception (LARC) methods leads to increased utilization of LARC and prevention of unintended pregnancies. It is unclear if immediate postpartum levonorgestrel-releasing intrauterine device (LNG-IUD) insertion has an effect on breastfeeding success. Study Design: This study was a secondary analysis of a randomized trial that compared intrauterine device (IUD) use at 6 months postpartum among women who underwent intracesarean IUD placement with women who planned for interval IUD placement at 6 or more weeks postpartum. This parallel, 1:1, nonblinded randomized trial was conducted between March 2012 and June 2014 at the University of North Carolina Women's Hospital. We recruited pregnant women aged 18-45 years who were undergoing a cesarean delivery and desired an IUD for contraception postpartum. Results: We received breastfeeding information from 63 women who desired to use a LNG-IUD. A proportion analysis demonstrated that there was no difference in the proportion of women breastfeeding at any of the three time points, 6, 12, and 24 weeks, following placement. This remained true after adjusting for age, parity, and ethnicity. Conclusion: This study adds to the existing body of evidence that shows that most women are able to successfully breastfeed after immediate postpartum LNG-IUD placement. Women should be encouraged to breastfeed, and the desire to breastfeed should not preclude the initiation of a postplacental IUD. This study provides reassurance that immediate postpartum LNG-IUD placement does not adversely affect breastfeeding; however, more high-quality data are needed on the impact of hormonal IUDs on breastfeeding outcomes.

Hormonal contraception, breastfeeding and bedside advocacy: the case for patient-centered care

Postpartum contraceptive decision making is complex, and recommendations may be influenced by breastfeeding intentions. While biologically plausible, concerns about the adverse impact of hormonal contraception on breast milk production have not been supported by the clinical evidence to date. However, the data have limitations, which can lead providers with different priorities around contraception and breastfeeding to interpret the data in a way that advances their personal priorities. Discrepancies in interpretations can lead to divergent recommendations for individual women and may cause conflict. Furthermore, providers must recognize that decision making about contraception and breastfeeding takes place in complex cultural, historical and socioeconomic contexts. Implicit bias may influence a provider's counseling. Unrecognized biases toward one patient or another, or one practice or another, may influence a provider's counseling. It is crucial for providers to strive to recognize their own biases. Providers need to respectfully recognize each patient's values and preferences regarding hormonal contraception and breastfeeding. Developing a patient-centered decision tool or implementing patient-centered interview techniques specifically around breastfeeding and contraception could help to minimize provider-driven variability in care.

"My Body. My Choice": A Qualitative Study of the Influence of Trust and Locus of Control on Postpartum Contraceptive Choice

Postpartum contraception helps reduce unintended pregnancy and space births to improve maternal and child health. This study explored women's perceptions of contraceptive choice during the postpartum period in the context of locus of control and trust in healthcare providers. Researchers conducted six focus groups with 47 women, ages 18-39, receiving postpartum care at an outpatient clinic. Techniques from grounded theory methodology provided an inductive approach to analysis. HyperRESEARCH 3.5.2 qualitative data analysis software facilitated a constant-comparative coding process to identify emergent themes. Participants expressed a preference for relationship-centered care, in which healthcare providers listened, individualized their approach to care through rapport-building, and engaged women in shared decision-making about contraceptive use through open communication, reciprocity, and mutual influence. Conflicting health messages served as barriers to uptake of effective contraception. While participants trusted their healthcare provider's advice, many women prioritized personal experience and autonomy in decisions about contraception. Providers can promote trust and relationship-centered care to optimize contraceptive uptake by listening, exploring patient beliefs and preferences about contraception and birth spacing, and tailoring their advice to individuals. Results suggest that antenatal contraceptive counseling should incorporate information about effectiveness, dispel misconceptions, and engage patients in shared decision-making.

Immediate postpartum levonorgestrel intrauterine device insertion and breast-feeding outcomes: a noninferiority randomized controlled trial

BACKGROUND

Immediate postpartum levonorgestrel intrauterine device insertion is increasing in frequency in the United States, but few studies have investigated the effect of early placement on breast-feeding outcomes.

OBJECTIVE

This study examined the effect of immediate vs delayed postpartum levonorgestrel intrauterine device insertion on breast-feeding outcomes.

STUDY DESIGN

We conducted this noninferiority randomized controlled trial at the University of Utah and the University of New Mexico Health Sciences Centers from February 2014 through March 2016. Eligible women were pregnant and planned to breast-feed, spoke English or Spanish, were aged 18-40 years, and desired a levonorgestrel intrauterine device. Enrolled women were randomized 1:1 to immediate postpartum insertion or delayed insertion at 4-12 weeks' postpartum. Prespecified exclusion criteria included delivery <37.0 weeks' gestational age, chorioamnionitis, postpartum hemorrhage, contraindications to levonorgestrel intrauterine device insertion, and medical complications of pregnancy that could affect breast-feeding. We conducted per-protocol analysis as the primary approach, as it is considered the standard for noninferiority studies; we also report the alternative intent-to-treat analysis. We powered the study for the primary outcome, breast-feeding continuation at 8 weeks, to detect a 15% noninferiority margin between groups, requiring 132 participants in each arm. The secondary study outcome, time to lactogenesis, used a validated measure, and was analyzed by survival analysis and log rank test. We followed up participants for ongoing data collection for 6 months. Only the data analysis team was blinded to the intervention.

RESULTS

We met the enrollment target with 319 participants, but lost 34 prior to randomization and excluded an additional 26 for medical complications prior to delivery. The final analytic sample included 132 in the immediate group and 127 in the delayed group. Report of any breast-feeding at 8 weeks in the immediate group (79%; 95% confidence interval, 70-86%) was noninferior to that of the delayed group (84%; 95% confidence interval, 76-91%). The 5% difference in breast-feeding continuation at 8 weeks between the groups fell within the noninferiority margin (95% confidence interval, -5.6 to 15%). Time to lactogenesis (mean ± SD) in the immediate group, 65.3 ± 25.7 hours, was noninferior to that of the delayed group, 63.6 ± 21.6 hours. The mean difference between groups was 1.7 hours (95% confidence interval, -4.8 to 8.2 hours), noninferior by log-rank test. A total of 24 intrauterine device expulsions occurred in the immediate group compared to 2 in the delayed group (19% vs 2%, P < .001), consistent with the known higher expulsion rate with immediate vs delayed postpartum intrauterine device insertion. No intrauterine device perforations occurred in either group.

CONCLUSION

Our results of noninferior breast-feeding outcomes between women with immediate and delayed postpartum levonorgestrel intrauterine device insertion suggest that immediate postpartum intrauterine device insertion is an acceptable option for women planning to breast-feed and use the levonorgestrel intrauterine device. Expulsion rates are higher with immediate postpartum levonorgestrel intrauterine device insertion compared to delayed insertion, but this disadvantage may be outweighed by the advantages of immediate initiation of contraception. Providers should offer immediate postpartum intrauterine device insertion to breast-feeding women planning to use the levonorgestrel intrauterine device.

Development and Evaluation of a Lactation Rotation for a Pediatric Residency Program

BACKGROUND

The American Academy of Pediatrics recommends that pediatricians promote and help manage breastfeeding. However, research has shown that they are not adequately prepared. To address this gap, a 2-week mandatory lactation rotation program was developed for first-year pediatric residents. Research aim: The aim of the study was to provide a lactation education program and to measure the residents' knowledge and perceived confidence regarding breastfeeding.

METHODS

This longitudinal self-report pretest/posttest study was conducted with a convenience sample of 45 first-year pediatric residents. Each resident spent a minimum of 50 hours with an International Board Certified Lactation Consultant. To measure breastfeeding knowledge and clinical confidence, the American Academy of Pediatrics' Breastfeeding Residency Curriculum pretest was used 4 times: first and last day of the rotation and at 6 and 12 months postrotation.

RESULTS

Test and confidence scores were evaluated. Statistically significant differences in knowledge were found between test 1 when compared with tests 2, 3, and 4 ( p < .001). No significant differences were found between tests 2, 3, and 4 ( p > .05). The abilities to "adequately address parents' questions" and to "completely manage common problems" were significant, with confidence increasing in tests 2, 3, and 4 ( p < .001).

CONCLUSION

As a result of an innovative, comprehensive educational lactation program, the pediatric residents' knowledge and perceived confidence related to breastfeeding significantly increased.

Effectiveness of an Online Natural Family Planning Program for Breastfeeding Women

OBJECTIVE

To analyze the effectiveness of an online, nurse-managed natural family planning (NFP) program among breastfeeding women and subgroups of these women.

DESIGN

Longitudinal comparative cohort study.

SETTING

A university-based online NFP education program and menstrual cycle charting system.

PARTICIPANTS

Women (N = 816) with a mean age of 30.3 years (standard deviation = 4.5) who registered to use the online NFP system and indicated they were breastfeeding.

METHODS

Participants tracked their fertile times with an electronic hormone fertility monitor (EHFM), cervical mucus monitoring, or both. All unintended pregnancies were evaluated by professional nurses.

RESULTS

The correct use pregnancy rates were 3 per 100 users over 12 cycles of use, and typical rates were 14 per 100 at 12 cycles of use. At 12 cycles of use, total pregnancy rates were 16 per 100 for electronic hormone fertility monitor users (n = 380), 81 per 100 among mucus-only users (n = 45), and 14 per 100 for electronic hormone fertility monitor plus mucus users (n = 391).

CONCLUSION

Use of a nurse-managed online NFP program for women can be effective to help women avoid pregnancy while breastfeeding, especially with correct and consistent use.

Postpartum intentions on contraception use and method choice among breastfeeding women attending a university hospital in Ohio: a cross-sectional study

BACKGROUND

Few postpartum women use effective contraception and those who use less effective methods have increased rates of unintended pregnancy. Little is known about postpartum contraception intentions among breastfeeding women. Our objectives were to measure the extent of prenatal contraceptive counseling, to assess contraceptive intentions, and to identify correlates of both among postpartum women who were planning to breastfeed.

METHODS

We conducted a cross-sectional study using a convenience sample of 100 breastfeeding women before their discharge following delivery at a large university hospital in 2015. We used logistic regression to assess three outcomes of interest: not intending to use contraception before 6 months postpartum, reporting receiving counseling on postpartum contraception during prenatal care, and considering the effects of contraception methods on the breastfeeding mother-infant dyad when choosing a postpartum contraception method.

RESULTS

Most women (91%) intended to use contraception. Prior history of no contraception use was the sole factor related to not intending to use contraception. The most commonly cited reason for the intended choice of contraceptive method was convenience (35%). Few women (21%) reported considering the effects of contraception methods on the breastfeeding dyad when choosing a postpartum contraception method. Nearly half of women reported never discussing postpartum contraception options with their healthcare provider during prenatal care. In the multivariate analysis, receiving public assistance was the only factor that remained statistically significantly associated with reporting having received contraception counseling during prenatal care.

CONCLUSIONS

Although most women intended to use contraception, they did not appear to have received adequate prenatal counseling on postpartum contraception.

Evidence-Based Methods That Promote Human Milk Feeding of Preterm Infants: An Expert Review

Best practices translating the evidence for high-dose human milk (HM) feeding for preterm infants during neonatal intensive care unit (NICU) hospitalization have been described, but their implementation has been compromised. Although the rates of any HM feeding have increased over the last decade, efforts to help mothers maintain HM provision through to NICU discharge have remained problematic. Special emphasis should be placed on prioritizing the early lactation period of coming to volume so that mothers have sufficient HM volume to achieve their personal HM feeding goals. Donor HM does not provide the same risk reduction as own mother's HM.

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.

Counseling during Maternal and Infant Health Visits and Postpartum Contraceptive use in Uttar Pradesh, India

CONTEXT

Postpartum family planning is a compelling concern of global significance due to its salience to unplanned pregnancies, and to maternal and infant health in developing countries. Yet, women face the highest level of unmet need for contraception in the year following a birth. A cost-effective way to inform women about their risk of becoming pregnant after the birth of a child is to integrate family planning counseling and services with maternal and infant health services.

METHODS

We use recently collected survey data from 2733 women from six cities in Uttar Pradesh, India who had a recent birth (since 2011) to examine the role of exposure to family planning information at maternal and infant health visits on (1) any contraceptive use in the postpartum period, and (2) choice of modern method in the postpartum period. We use discrete-time event history multinomial logit models to examine the duration to contraceptive use, and choice of modern method, in the 12 months following the last birth since 2011.

RESULTS

We find that receiving counseling in an institution at the time of delivery has the strongest influence on women's subsequent uptake of modern contraception (female sterilization and IUD). Being visited by a CHW in the extended postpartum period was also strongly associated with subsequent uptake of modern contraception (IUD, condom and hormonal contraception).

CONCLUSION

Providing postpartum family planning counseling at key junctures during maternal health visits has the potential to increase uptake of modern contraceptive method in urban Uttar Pradesh.

Committee Opinion No. 658: Optimizing Support for Breastfeeding as Part of Obstetric Practice

Although most women in the United States initiate breastfeeding, more than one half wean earlier than they desire. As reproductive health experts and advocates for women's health who work in conjunction with other obstetric and pediatric health care providers, obstetrician-gynecologists are uniquely positioned to enable women to achieve their infant feeding goals. The American College of Obstetricians and Gynecologists recommends exclusive breastfeeding for the first 6 months of life, with continued breastfeeding as complementary foods are introduced through the infant's first year of life, or longer as mutually desired by the woman and her infant. Because lactation is an integral part of reproductive physiology, all obstetrician-gynecologists and other obstetric care providers should develop and maintain knowledge and skills in anticipatory guidance, physical assessment and support for normal breastfeeding physiology, and management of common complications of lactation. Obstetrician-gynecologists and other obstetric care providers should support each woman's informed decision about whether to initiate or continue breastfeeding, recognizing that she is uniquely qualified to decide whether exclusive breastfeeding, mixed feeding, or formula feeding is optimal for her and her infant. Obstetrician-gynecologists and other obstetric care providers should support women in integrating breastfeeding into their daily lives in the community and in the workplace. The offices of obstetrician-gynecologists and other obstetric care providers should be a resource for breastfeeding women through the infant's first year of life, and for those who continue beyond the first year.

Reliance on Pumped Mother's Milk Has an Environmental Impact

Breastfeeding is an environmentally friendly process; however when feeding relies on pumped mother’s milk, the environmental picture changes. Waste plastics and heavy metals raise concerns regarding resource efficiency, waste treatment, and detrimental effects on health. Reliance on pumped milk rather than breastfeeding may also effect obesity and family size, which in turn have further environmental impacts. Information on pump equipment rarely includes environmental information and may focus on marketing the product for maximum profit. In order for parents, health workers, and health policy makers to make informed decisions about the reliance on pumped mother’s milk, they need information on the broad and far reaching environmental aspects. There was no published research found that examined the environmental impact of using pumped mother’s milk. A project is ongoing to examine this issue.

Canadian Contraception Consensus (Part 3 of 4): Chapter 8 - Progestin-Only Contraception

OBJECTIVE

To provide guidelines for health care providers on the use of contraceptive methods to prevent pregnancy and on the promotion of healthy sexuality.

OUTCOMES

Overall efficacy of cited contraceptive methods, assessing reduction in pregnancy rate, safety, ease of use, and side effects; the effect of cited contraceptive methods on sexual health and general well-being; and the relative cost and availability of cited contraceptive methods in Canada.

EVIDENCE

Published literature was retrieved through searches of Medline and The Cochrane Database from January 1994 to January 2015 using appropriate controlled vocabulary (e.g., contraception, sexuality, sexual health) and key words (e.g., contraception, family planning, hormonal contraception, emergency contraception). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English from January 1994 to January 2015. Searches were updated on a regular basis in incorporated in the guideline to June 2015. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

VALUES

The quality of the evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). CHAPTER 8: PROGESTIN-ONLY CONTRACEPTION: Summary Statements Recommendations.

Breastfeeding and Contraception

Research data acquired from six up-to-date references on the effects of contraception methods and breastfeeding. Areas of interest are advantages, disadvantages, and effects on breastfeeding. There are no clear findings from these articles; the research studies have small parameters. However, they do provide needed education for our mothers in acquiring which contraception method fits their lifestyle and breastfeeding goal.
