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.

Perspectives on maternal, infant, and young child nutrition and family planning: Considerations for rollout of integrated services in Mara and Kagera, Tanzania.

In Lake Zone, Tanzania, low contraceptive prevalence, closely spaced births, and child stunting are common. Synergies exist between postpartum family planning (PPFP) and maternal, infant, and young child nutrition (MIYCN), yet health services are often provided in silos. This qualitative formative research study aimed to identify barriers and facilitating factors for optimal nutrition and PPFP practices in Mara and Kagera, Tanzania. Results informed the program design of an integrated nutrition and family planning (FP) implementation approach. The study involved in-depth interviews with mothers of infants under 1 year (n = 24), grandmothers (n = 12), health providers (n = 6), and traditional birth attendants (n = 12), and 14 focus group discussions with community health workers, fathers, and community leaders. Findings reveal that breastfeeding initiation was often delayed, and prelacteal feeding was common. Respondents linked insufficient breast milk to inadequate maternal nutrition-in terms of the quality of the diet and small quantities of food consumed by mothers. Breast milk insufficiency was addressed through early introduction of foods and liquids. Mothers believed that breastfeeding prevents pregnancy, regardless of the frequency or duration of breastfeeding, yet were generally not aware of the lactational amenorrhea method (LAM) of FP. Joint decision-making on FP was viewed as important, and women often discussed it with their partner. Future programming should address misconceptions about return to fecundity knowledge gaps and concerns about FP methods including LAM; and perceptions regarding insufficient breast milk and early introduction of foods which are impediments to optimal MIYCN and FP practices.

Maximizing Opportunities: Family Planning and Maternal, Infant, and Young Child Nutrition Integration in Bondo Sub-County, Kenya.

Purpose This article shares learning from an innovative demonstration program integrating maternal, infant, and young child nutrition (MIYCN) and family planning (FP) services in western Kenya, providing recommendations for future work to expand MIYCN and FP integration. Description Six health facilities reorganized to integrate MIYCN and FP services and community health volunteers (CHVs) promoted MIYCN and FP in adjacent communities in Bondo Sub-County over a 1-year period. At the facility level, each provider was directed to provide both sets of services in a single room during FP, antenatal care, postnatal care, or child consultation visits (a "one stop shop" approach). At community level, CHVs were to conduct household visits equipped with new integrated materials and incorporate MIYCN and FP within community activities. Assessment Although the "one stop shop" approach, where one provider offers all integrated services in one room, was initially proposed for all facilities, this worked most effectively in the dispensary and health centers. The sub-county hospital adapted the approach such that integrated services were offered by more than one provider during a visit, with clients linked from one provider to another through same-day intra-facility referrals. CHVs were generally able to incorporate MIYCN and FP content within household visits and community activities; however some knowledge gaps were noted after initial training, necessitating additional refresher training. Conclusion This demonstration experience revealed that future replication efforts should enable sub-county team leadership, assess facility readiness, streamline data collection, build local buy-in, and prioritize dispensaries and health centers with high client loads.

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.

An overview of contraception in women with obesity.

The use of safe and effective contraception is essential for preventing unplanned pregnancy in women of all body sizes. When counseling women with obesity about contraception, it is important to consider the pharmacokinetic alterations of obesity on various modern contraceptive methods. However, evidence is reassuring that most contraceptive methods are safe and effective in women with obesity. Individual countries and the World Health Organization have published Medical Eligibility Criteria to guide contraceptive selection in women with medical issues including obesity. When choosing contraception, specific risks of the method relative to any underlying medical disorders must also be balanced against the risks of unintended pregnancy in this group.

Male partner influence on Women's choices and utilisation of family planning services in Mufulira district, Zambia.

Background: Family planning services are essential in reducing maternal deaths as well as improving the reproductive and sexual health of women. Although family planning services are frequently focused on women, men are often the primary decision-makers. We conducted a study to explore male partner influence on women's choices and utilisation of family planning services in Mufulira district, Zambia. Methods: A qualitative explorative study design that utilised two focus group discussions (n = 20) and in-depth interviews (n = 30) involving women of reproductive age was conducted. Convenient sampling was employed to select participants. In-depth interviews and focus group discussions were recorded, translated, and transcribed verbatim. Content analysis was utilised through code classification and theme identification. Data were imported into NVivo.×64 for coding and node generation. Findings: The study revealed key themes on male partner influence on contraception use such as fear of infidelity, fear of physical abuse, preference for a large family size , disruption of sexual pleasure, and perceived side effects of contraceptives. These themes highlight the influence of culturally driven gender and power dynamics on male partner attitudes towards contraception. Participants described how their male partners exhibited prenatal attitudes and control over them thereby limiting their decision-making power on contraception use. Undesirable contraception side effects such as reduced vaginal lubrication contributed to sexual pleasure disruption among men. Concerns that women's use of contraception can lead to infidelity also contributed to male partner disapproval of contraception use. Conclusions: Understanding barriers to contraception utilisation presented by male partners is essential in preventing contraception discontinuation and can increase contraception uptake among women. Our findings highlight the influence of culturally driven gender and power dynamics on male partner attitudes towards contraception. Therefore, male partner education on family planning services is key. Also, men need to be incorporated as key stakeholders when planning and implementing family planning programmes.

Trends and predictors of modern contraceptive use among married women: Analysis of 2000-2016 Ethiopian Demographic and Health Surveys.

Objectives: Accessing family planning is a key investment in reducing the broader costs of health care and can reduce a significant proportion of maternal, infant, and childhood deaths. In Ethiopia, use of modern contraceptive methods is still low but it is steadily increasing. Identifying the contributing factors to the changes in contraceptive use among women helps to improve women's contraceptive use and helps to plan strategies for family planning programs. Thus, the current study aimed to analyze the trends and predictors of changes in modern contraceptive use over time among married women in Ethiopia. Data source and study design: Secondary data analysis of the national representative data of 2000-2016 Ethiopian Demography and Health Survey was employed. Methods: This secondary data analysis was considered using 2000 through 2016 Ethiopian Demographic and Health Surveys. The study used data from the four DHSs conducted in Ethiopia (2000-2016). The data from all EDHS was collated so as to follow the trends throughout the period considered for the survey. Married women aged 15-49 years with sample sizes of 36,721 (9,203 in 2000, 8,438 in 2005, 9,478 in 2011, and 9,602 in 2016) were included. The analysis involved three levels, including trend analysis (to see changes from 2000 to 2005, 2005-2011, 2011-2016 and 2000-2016). Bivariate and multivariate analysis were also considered to identify predictors of modern contraceptive use. Data was extracted from the EDHS datasets for which authorization was obtained from the DHS Program/ICF International using a data extraction tool. SPSS 24 was employed for data management and analysis. Results: Among married women of reproductive age, modern contraceptive prevalence increased from 6.2% in 2000 to 35.2% in 2016. This 5-fold increment in modern contraceptive use was due to being in the age group of 25-29 years (AOR = 1.4; 95%CI (1.1, 1.7)), having two children (AOR = 1.3; 95%CI (1.1, 1.6)), the richest wealth category (AOR = 3.0; 95% CI (2.5, 3.5)), currently working (AOR = 1.3; 95%CI (1.2, 1.5)) and attending secondary and above education (AOR = 1.2; 95%CI (1.1, 1.6)) were found to be predictors. Conclusions: Over the past 15 years, an annual average of a 1.9% point increment has been observed in modern contraceptive use, but the country lags behind the SDGs's 2030 target of achieving zero unmet needs for contraception. Program interventions, and continued education of women, are mandatory, as education is one of the major factors contributing to increasing contraceptive use.

Implementing a Novel Facility-Community Intervention for Strengthening Integration of Infant Nutrition and Family Planning in Mara and Kagera, Tanzania.

Tanzania has high fertility, low contraceptive prevalence and low exclusive breastfeeding (EBF). The Lake Zone, including Mara and Kagera regions, leads the country in total fertility; use of the lactational amenorrhea method (LAM) is negligible. This pre-/post-study explored the effects of a multi-level facility and community intervention (service delivery support, community engagement, media and LAM tracking) to integrate maternal and infant nutrition and postpartum family planning (FP) within existing health contacts. Mixed methods were used, including service statistics, exit interviews, patient-tracking tools for community health workers, client self-tracking tools, supervision data, focus group discussions and in-depth interviews. Results are presented using the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) implementation science framework. The intervention reached primarily the second and fourth wealth quintiles, increased FP and EBF at six weeks postpartum. LAM was very acceptable, provided an entry point for FP conversations and for addressing misconceptions, and reinforced EBF practices. Partners felt encouraged to support spousal nutrition, breastfeeding and FP. Higher adoption in Kagera may be influenced by performance-based financing. The intervention was implemented with generally high fidelity. Maintenance data reflected stakeholder interest in continuing the intervention. A multi-level facility and community intervention was feasible to implement and likely contributed to improved EBF practices and FP uptake, including LAM use.

Do Expectant Mothers' Breastfeeding Plans Influence Provider Prenatal Contraceptive Counseling?

BACKGROUND: Breastfeeding and optimal birth spacing are associated with improved maternal and infant health outcomes worldwide. Provision of contraceptive advice that is aligned with recommendations for breastfeeding has potential to maximize maternal and infant health. Although there is broad agreement regarding the breastfeeding compatibility of specific postpartum contraceptive methods, it is not known whether maternal breastfeeding intention influences prenatal provider contraceptive counseling. RESEARCH AIM: We aimed to determine if maternal feeding intention is considered by prenatal providers during contraceptive counseling. METHODS: This was a cross-sectional online author-created survey including all prenatal providers (N = 40) at two academic safety-net institutions in Cleveland, Ohio. Of 100 obstetrics/gynecology faculty members, 40 (40%) completed the survey, which included multiple-choice questions. Nominal and ordinal survey results were reported with percentages and frequencies, and categorical variables were compared using the Fisher exact test. RESULTS: Participants appropriately promoted breastfeeding-compatible postplacental intrauterine device placement, even though maternal feeding intention was specifically considered by just 12 (30%). Endorsed barriers to contraception for breastfeeding mothers included provider medical worries, patient concerns, and colleague resistance. Postplacental levonorgestrel intrauterine devices were recommended for all mothers by 92.5% of participants (n = 37). Recommendations regarding progestin-only and combined oral contraceptive pills were influenced by maternal breastfeeding versus formula-feeding intention. CONCLUSION: Asking expectant women about their feeding intentions within each contraceptive discussion may create opportunities for shared decision making that can optimize perinatal outcomes for both mother and infant worldwide.

Progesterone vaginal ring as a new contraceptive option for lactating mothers: Evidence from a multicenter non-randomized comparative clinical trial in India.

OBJECTIVES: Evaluate and compare contraceptive efficacy, safety, continuation rates and duration of lactational amenorrhea (LA) in married lactating women (20-35 years) using the progesterone vaginal ring (PVR) or Copper-T380A intrauterine device (IUD) during the first postpartum year. STUDY DESIGN: We conducted a one-year multicenter, non-randomized, non-inferiority, open-label, comparative trial at 20 centers in India and compared efficacy, safety, continuation and LA plus feeding patterns and growth/well-being of participants' infants. Women used four 3-month PVRs consecutively (lost PVRs were not replaced) and were to breastfeed at least four times/day. We used Pearl Index (PI) and Kaplan Meier (K-M) rates to analyze pregnancy and K-M for continuation. RESULTS: We enrolled 789 women (459 PVR, 330 IUD). Neither PI nor K-M one-year pregnancy rates differed significantly between groups (PI: PVR-0.62; IUD-0.35); (K-M: PVR-0.7; IUD-0.4, p = 0.58). Continuation rates at 12 months were 78.5% (IUD) vs. 56.9% (PVR) (p < 0.001). Ring expulsions and menorrhagia were the most common discontinuation among PVR/IUD users respectively. The median duration of LA among PVR vs. IUD users was 405 vs. 120 days (p < 0.001). Both groups reported similar adverse events (PVR: 24.2%; IUD: 23.0%); there were no serious adverse events among PVR users. Infants from both groups fed 12-7 times/day and grew at expected rates. CONCLUSIONS: Efficacy and safety outcomes were comparable among women in both groups. Continuation rates for PVR, a woman-controlled method, were shorter than IUD rates while PVR users maintained LA significantly longer than IUD users. Infant breastfeeding and growth patterns/well-being were favorable in both groups. IMPLICATIONS: PVR, a user-controlled device, offers an additional contraceptive choice for lactating women for one-year postpartum use and can help to address the unmet need for contraception among postpartum women while encouraging breastfeeding to enhance infant growth and well-being.

Counseling and in-advance provision of levonorgestrel emergency contraceptive pills decrease the rate of unplanned pregnancy during breastfeeding: a randomized controlled trial.

OBJECTIVE: To evaluate the effect of counseling and in-advance provision of levonorgestrel emergency contraceptive pills (LNG-ECPs) during postpartum counseling on the incidence of occurrence of unplanned pregnancy during breastfeeding. MATERIALS AND METHODS: The current study is an open-label, parallel, randomized controlled trial carried out in a university hospital in Egypt. All women who delivered and planning to birth-space and breastfeed for at least 1 year were approached for participation during a postpartum hospital stay. Eligible participants were randomly allocated to receive adequate lactational amenorrhea method (LAM) counseling Group 1 (LAM-only) or the above LAM counseling in addition to counseling and in advance provision of one packet of 0.75-mg LNG-ECPs Group 2 (LAM + EC). The two study groups were followed 6 months and the primary outcome was the unplanned pregnancy rate. RESULTS: The study included 2708 women randomized into two groups; LAM-only and LAM + EC groups. Demographic characteristics were homogenous between the groups at the time of recruitment. Unplanned pregnancy was significantly higher in LAM-only group 70 (5.3%) as compared with 5 (0.4%) in LAM-EC group (p = .0001). Also, 619 women (46.6%) used LNG-ECPs with minor side effects like nausea in 175 (28.3%) women, headache in 94 (15.2%) women, vomiting in 24 (3.9%) women. CONCLUSION: In-advance counseling and provision of LNG-ECPs for those opt to use LAM during postpartum family planning counseling can decrease the rate of unplanned pregnancy during breastfeeding and increase the initiation of long-term use of contraception.

Knowledge and Opinions of Postpartum Mothers About the Lactational Amenorrhea Method: The Turkish Experience.

OBJECTIVE: This study was performed to investigate mothers' opinions and knowledge about the contraceptive feature of breastfeeding. BACKGROUND: Breastfeeding is quite beneficial in terms of mother, baby, and public health. Although it has long been known to have a contraceptive effect and although it is common in many countries, women usually do not use it as a contraceptive method. MATERIALS AND METHODS: This is a descriptive study and included 400 mothers in their early postpartum period. Data were collected with a questionnaire at face-to-face interviews within 3 days of giving birth. Obtained data were analyzed with descriptive statistics. RESULTS: One third of the mothers were primiparous and 66.5% of the mothers had breastfeeding experience. Of these, 38.9% of the mothers said that they received knowledge about the contraceptive effect of breastfeeding and 68.9% of these mothers received this knowledge from a nurse. Seventeen percent of the mothers receiving this knowledge reported that breastfeeding was a contraceptive and 1.8% of the mothers reported that it was sometimes contraceptive. Around 41.3% of the mothers thought that they would be able to use breastfeeding as a contraceptive method. Almost all the mothers wanted to get information about the contraceptive feature of breastfeeding. CONCLUSIONS: As our research shows, four of every five mothers in their early postpartum period turned out to believe that breastfeeding was not contraceptive, although the mothers are very eager and ready for this information. Therefore, it is important that health professionals providing antenatal and postnatal counseling about breastfeeding and contraception should offer women accurate information about this method.

Knowledge and associated factors of lactational amenorrhea as a contraception method among postpartum women in Aksum town, Tigray Region, Ethiopia.

OBJECTIVES: The objective of the study was to assess the prevalence of knowledge level and predictors of lactational amenorrhea method (LAM) as method of contraception among women who gave birth a year prior to the study period in the Aksum town, Tigray Region. The study was cross sectional in design conducted from March 25 to April 24, 2015. Results of the study could help the design of family planning strategies. RESULTS: The knowledge status of LAM as a contraceptive method was 8.8% [95% CI 6.4-11%)]. Women who delivered at health institution (AOR = 1.4, 95% CI 1.2-4.3), attended postnatal care (AOR = 1.3, 95% CI 1.2-3.0) and visited home and counseled about family planning by health extension in the last 12 months, (AOR = 1.5, 95% CI 1.3-4.0) were more likely found knowledgeable towards LAM. Secondary and above level of the maternal education was also found a significant predictor variable with LAM as a contraceptive method (AOR = 1.2 95% CI 1.1-4.0). Our findings recommend that to address the knowledge gap of mothers; improving the uptake of maternal health services and strengthening family planning counseling at home are a key area for improving the knowledge level of LAM.

Testing a proof of concept model for group couples counseling in family planning in Northern Uganda.

INTRODUCTION: The post-conflict Acholi sub-region of Uganda is undergoing a period of transition that is influencing access, acceptability and use of family planning (FP). Low FP use and high unmet need for FP in Uganda's northern region provides a unique opportunity to test a community-based group counseling approach to reduce unintended pregnancies among young couples. We share findings from a proof of concept testing model in delivering fertility awareness methods (FAM) to groups of couples by trained non-health community youth agents. METHODS: The group counseling model was developed for couples interested in two FAM-standard days method (SDM) and TwoDay Method-within rural communities in Northern Uganda. WALAN was tested in a three-month proof of concept phase, employing 24 direct observations of group counseling sessions; quantitative interviews with 9 couples using either SDM or TwoDay Method; 2 focus group discussions with youth facilitators, and; 9 key informant interviews with providers and leaders. RESULTS: The proof of concept results suggest model feasibility and acceptability among participating communities. Couples learned how to use FAM correctly. All 9 interviewed female users reported 100% correct knowledge of method use. Couples also reported high levels of satisfaction for both methods. SDM and TwoDay Method participants reported comfort and satisfaction in learning about FAM in small groups with other couples. CONCLUSION: The proof of concept phase confirmed intervention feasibility, albeit with some model adjustments. The results were used to inform the pilot intervention, launched in April 2016 within 15 other villages in the same region.

[Natural Family Planning methods and Barrier: CNGOF Contraception Guidelines]. / Méthodes de contraception naturelle et méthodes barrières. RPC contraception CNGOF.

OBJECTIVE: To develop clinical practice recommendations for the use of natural contraception and female and male barrier methods. MATERIALS AND METHODS: A systematic review of English and French literatures related to the safety and effectiveness of natural contraceptive methods based on PubMed, Cochrane Library, practice recommendations issued by international scientific societies and guidelines provided by the World Health Organization (WHO) as well as updates from the Center for Disease Control and Prevention (CDC). RESULTS: Natural contraceptives methods include fertility awareness-based methods, lactational amenorrhea method (LAM) and withdrawal method. The prevalence is low (4.6% of users) and remains stable over the years. Identification of the fertile period can be symptom-based cervical mucus (Billings), two-day method, basal body temperature, symptom-thermal method or based on calendar calculation (Ogino-Knauss, standard day method). Pregnancy rate after one-year utilization varies from 0.4% to 5% in perfect use but 8% in common practice. Effectiveness increases with absence of vaginal sex and decreases when combined to barriers method inadequately implemented. Data is scarce on reliability and effectiveness of ovulation predictor kits readily available on internet. Lactational amenorrhea method (LAM) can be very effective (98%) provided three conditions are fulfilled: within 6 months after birth, amenorrhea is effective, and breastfeeding is exclusive or quasi exclusive (day/night). Withdrawal method is constraining and of limited effectiveness. Male and female condom, diaphragm, cervical cap and spermicides are mechanical and chemical barrier methods, preventing spermatozoids from passing through the cervix into the uterus and therefore preventing fecundation. Female and male condoms offer a double protection to avoid pregnancy and prevent STD's. They are effective provided strict conditions of use are fulfilled. Male condom is favored by teenagers (45.6% among 15 to 19 years old), sometimes in combination with contraceptive pill (16% of cases). Women on the pill decreases according to their age. Pregnancy rates within the first year of consistent and correct use of these methods vary between 5 to 26% and reach 20 to 32% in practical use. Diaphragm and cervical cap need to be used in combination with spermicides. Spermicides have limited effectiveness when used alone. CONCLUSION: In common practice, natural and barrier contraceptive methods are more constraining and less effective than modern contraceptive method. They can be an alternative at given time and/or in situations where the women or the couple accept the possibility of an unexpected pregnancy which might be terminated or not. Women/couples need to be properly informed on how to use such methods, on their disadvantages and possible failures in common practice. Reminders are to be given on emergency contraceptive methods (IUD, hormonal) after unprotected sex.

Enhancing contraceptive choice for postpartum women in sub-Saharan Africa with the progesterone vaginal ring: a review of the evidence.

It is increasingly recognized that women who have just given birth have a high unmet need and require contraceptive protection in the first year postpartum. A majority of women in developing countries do breastfeed exclusively but for short durations, hence they may be sometimes unknowingly exposed to the risk of pregnancy if they are relying on nursing for contraceptive protection. The WHO's Medical Eligibility Criteria for Contraceptive Use recommends the use of different contraceptives in the first year postpartum depending on whether the woman is nursing or not and the time since delivery. Some of the options available for breastfeeding women include implants, IUDs and injectables, which can be obtained only from a trained family planning provider. Since 2013, Population Council has been carrying out a study in Senegal, Nigeria, and Kenya to assess the acceptability of progesterone vaginal ring (PVR) as a new contraceptive option designed specifically for use by breastfeeding women to extend the period of lactational amenorrhea and promote birth spacing. Breastfeeding in sub-Saharan Africa is near universal with fairly long durations, a situation that increases the effectiveness of PVR. Each ring delivers a daily dose of 10 mg of progesterone and can be used continuously up to 3 months with a woman being able to continue with its use up to 1 year (four rings used consecutively). Preliminary results indicate that many women who had used the method found it acceptable and their partners supported its use. Activities aimed at having PVR registered and made available in focal countries are ongoing. Integration of family planning and immunization services for mothers and their newborns will be a key strategy in introducing PVR into targeted health care markets. Given that the use of PVR does not require extensive clinical training, it will be easier to integrate it at all levels of the health system from tertiary health facilities to community-based services. The PVR has been recently included in the WHO Model List of Essential Medicines and the WHO's fifth edition of the Medical Eligibility Criteria for Contraceptive Use which should facilitate its introduction into the public and private sectors.

Transition from the Lactational Amenorrhea Method to other modern family planning methods in rural Bangladesh: barrier analysis and implications for behavior change communication program intervention design.

The timely transition from Lactational Amenorrhea Method (LAM)(2) to another modern family planning method contributes to healthy spacing of pregnancies by increasing the adoption of family planning during the first year postpartum. Yet, literature suggests challenges in completing a timely LAM transition. To guide program implementation in Bangladesh, this study identified factors influencing women's transition decisions. Eighty postpartum women, comprising 40 who transitioned from LAM(3) and 40 who did not,(4) participated. Half of each group participated in in-depth interviews to explore the decision-making process. All participants responded to a "Barrier Analysis" questionnaire to identify differences in eight behavioral determinants. More than half of transitioners switched to another modern method before or within the same month that LAM ended. Of the 18 transitioners who delayed,(5) 15 waited for menses to return. For non-transitioners, key barriers included waiting for menses to return, misconceptions on return to fertility, and perceived lack of familial support. The LAM transition can help women prevent unintended pregnancy during the first year postpartum. Increased emphasis on counseling women about the risk of pregnancy, and misconceptions about personal fertility patterns are critical for facilitating the transition. Strategies should also include interventions that train health workers and improve social support.

Troubled sleep: Night waking, breastfeeding and parent-offspring conflict.

Disrupted sleep is probably the most common complaint of parents with a new baby. Night waking increases in the second half of the first year of infant life and is more pronounced for breastfed infants. Sleep-related phenotypes of infants with Prader-Willi and Angelman syndromes suggest that imprinted genes of paternal origin promote greater wakefulness whereas imprinted genes of maternal origin favor more consolidated sleep. All these observations are consistent with a hypothesis that waking at night to suckle is an adaptation of infants to extend their mothers' lactational amenorrhea, thus delaying the birth of a younger sib and enhancing infant survival.
