RESUMO
Perinatal services are being challenged to acknowledge that not all pregnant and birthing people are women and to ensure the design and delivery of services that are inclusive of, and deliver equitable outcomes for, trans, non-binary, and other gender diverse people. This is posing unique challenges for midwifery with its women-centred philosophy and professional frameworks. This paper presents the critical reflections of midwifery educators located in two midwifery programmes in Aotearoa1 and Ontario Canada, who are engaged in taking up the challenge of trans and non-binary inclusion in their local contexts. The need to progress trans and non-binary inclusion in midwifery education to secure the human rights of gender diverse people to safe midwifery care and equitable perinatal outcomes is affirmed. We respond to an existing lack of research or guidance on how to progress trans and non-binary inclusion in midwifery education. We offer our insights and reflections organised as four themes located within the frameworks of cultural humility and safety. These themes address midwifery leadership for inclusion, inclusive language, a broader holistic approach, and the importance of positioning this work intersectionally. We conclude by affirming the critical role of midwifery education/educators in taking up the challenge of trans and non-binary inclusion to ensure a future midwifery workforce skilled and supported in the provision of care to the growing gender diverse population.

This review aimed to better understand the underlying physiology of the risks and benefits of bed-sharing. Eight databases were searched using terms relating to adult-infant/baby, bed-sharing/co-sleeping combined with outcome terms for physiology, sleep, cardiovascular, respiratory, temperature and behaviour. Of 836 papers identified, 59 papers representing 48 cohorts met inclusion criteria. Objective data using various methodologies were available in 27 papers and subjective data in 32 papers. Diverse measures were reported using variable definitions of bed-sharing. Identified physiological and behavioural differences between bed-sharing and cot-sleeping included increased behavioural arousals, warmer in-bed temperatures and increased breastfeeding duration in bedshare infants as well as differences in infant overnight sleep architecture, cardiorespiratory control and cortisol responses to stress. We concluded that many differences are context-specific, and dependent on the subjective view of the parents and their cultural values. Objective risk arises if the infant is unable to mount an appropriate physiological or behavioural response to their micro-environment. More studies in the bed-sharing setting are needed to identify infant risk, the potential benefits of a safer environment, and how bed-sharing interacts with infant care practices other than sleep.

BACKGROUND: Becoming a competent midwife is a complex process. The aim of midwifery education is to support the development of competence in midwifery skills, knowledge and to prepare graduates to meet the responsibilities inherent in the midwifery role. AIM: To explore the experiences of our alumni midwives, ask how well they perceived their midwifery programme had prepared them for beginning midwifery practice and to identify any curriculum changes, or postgraduate study topics, that would support the transition to midwifery practice. METHODS: An online survey was conducted with alumni of a Bachelor of Midwifery programme (New Zealand) who graduated between 2011 and 2014. The quantitative data were analysed using descriptive statistics, and a general inductive approach was used to develop themes from the qualitative data in the comment boxes. FINDINGS: Forty-two alumni viewed becoming a midwife as a blend/combination of: (1) gaining the knowledge and practical skills required for the profession; (2) management skills in areas of running a business, working with other people, navigating local procedures and processes effectively, and balancing work with personal life; (3) gaining confidence in one's competence, and (4) having support along the way. DISCUSSION: Competence in current evidence-based midwifery knowledge and practice is important in educating midwifery students. However, to transition to practice, a supportive environment is needed to assist midwives to develop self-management, business skills, and the confidence to negotiate and collaborate with colleagues and other health professionals. CONCLUSIONS: Not only did midwifery knowledge and practice skills matter for alumni, but also the acquisition of management skills, strategies for building confidence, and ongoing support. Content that facilitates these requirements should be included in midwifery programmes to support the transition from student to practitioner.

BACKGROUND: Although breastfeeding duration in New Zealand's indigenous Maori is shorter than in non-Maori, we know little about barriers or motivators of breastfeeding in this community. The aim of this analysis was to identify predictors for extended duration of breastfeeding amongst participants drawn from predominantly Maori communities in regional Hawke's Bay. METHODS: Mother/baby dyads were recruited from two midwifery practices serving predominantly Maori women in mostly deprived areas, for a randomised controlled trial comparing the risks and benefits of an indigenous sleeping device (wahakura) and a bassinet. Questionnaires were administered at baseline (pregnancy) and at one, three and six months postnatal. Several questions relating to breastfeeding and factors associated with breastfeeding were included. The data from both groups were pooled to examine predictors of breastfeeding duration. RESULTS: Maori comprised 70.5% of the 197 participants recruited. The median time infants were fully breastfed was eight weeks and Maori women were more likely to breastfeed for a shorter duration than New Zealand European women with an odds-ratio (OR) of 0.45 (95% CI 0.24, 0.85). The key predictors for extended duration of breastfeeding were the strong support of the mother's partner (OR = 3.64, 95% CI 1.76, 7.55) or her mother for breastfeeding (OR = 2.47, 95% CI 1.27, 4.82), longer intended duration of maternal breastfeeding (OR = 1.02, 95% CI 1.00, 1.03) and being an older mother (OR = 1.07, 95% CI 1.02, 1.12). The key predictors for shorter duration of breastfeeding were pacifier use (OR = 0.28, 95% CI 0.17, 0.46), daily cigarette smoking (OR = 0.51, 95% CI 0.37, 0.69), alcohol use (OR = 0.54, 95% CI 0.31, 0.93) and living in a more deprived area (OR 0.40, 95% CI 0.22, 0.72). CONCLUSIONS: Breastfeeding duration in this group of mainly Maori women was shorter than the national average. Increasing the duration of breastfeeding by these mothers could be further facilitated by ante and postnatal education involving their own mothers and their partners in the support of breastfeeding and by addressing pacifier use, smoking and alcohol use.

OBJECTIVE: to consolidate existing research in the field of sibling attended birth (SAB) into a body of knowledge to inform decision-making processes and guide midwifery practice throughout the sibling attended birth experience. DESIGN: An integrative literature review. DATA SOURCES: CINAHL Complete, Cochrane Library, PubMed, Index New Zealand, Australia/New Zealand Reference Centre, grey literature databases REVIEW METHODS: An extensive search of five electronic databases as well as 17 grey literature databases was conducted. Abstracts of 2340 papers and full texts of 39 papers were scrutinised for inclusion criteria leading to 22 studies being included in this review. The Crowe Critical Appraisal Tool was used to facilitate a systematic quality appraisal process. FINDINGS: This review included 22 studies (13 qualitative, 4 quantitative and 5 mixed methods). Studies were analysed using a narrative synthesis approach. Publications mainly focussed on families' motivations for choosing SAB, the preparation for the event, and the impact of SAB on children's behaviour and the infant/sibling relationship. CONCLUSIONS: This review identified that children experienced birth as a positive, exciting and important life event and parents viewed their SAB experiences as overwhelmingly positive and reported a heightened sense of family unity. Included studies did not address the long term effects of sibling attended birth, however, in the short-term, children did not show signs of trauma or severe distress, though differing levels of transient fear and anxiety were described. IMPLICATIONS FOR PRACTICE: Families could benefit from receiving evidence based information to enable an informed decision regarding their children's involvement during pregnancy, birth and the immediate postpartum. Information shared by the midwife could focus on how families can achieve an optimal SAB experience for all family members.

AIM: The aim of this study was to identify the potential risks and benefits of sleeping infants in a Pepi-Pod distributed to families with high risk of sudden unexpected death in infancy compared to a bassinet. METHODS: Forty-five mostly indigenous Maori mothers who were referred by local health providers to receive a Pepi-Pod were surveyed at recruitment, 1 and 3 months. A sleep study at 1 month included infrared video, oximetry and temperature measures. RESULTS: When compared with 89 historical bassinet controls, an intention-to-treat analysis of questionnaires showed no increase in direct bed sharing but demonstrated significantly less sharing of the maternal bedroom at both interviews, with the majority of those not sleeping in the maternal bedroom, actually sleeping in the living room. The 1 month 'as-used' analysis showed poorer maternal sleep quality. The 'as-used' analysis of video data (24 Pepi-Pod and 113 bassinet infants) also showed no increase in direct bed sharing, head covering or prone/side sleep position. Differences in oxygen saturation were not significant, but heart rate was higher in the Pepi-Pod infants by 8.37 bpm (95% confidence interval 4.40, 12.14). Time in the thermal comfort zone was not different between groups despite Pepi-Pod infants being situated in significantly warmer rooms. CONCLUSIONS: Overall, we found that most differences in infant risk behaviours in a Pepi-Pod compared to a bassinet were small, with confidence intervals excluding meaningful differences. We noted poorer maternal sleep quality at 1 month. Higher infant heart rates in the Pepi-Pod group may be related to higher room temperatures. The Pepi-Pod appears physiologically safe but is associated with lower reported maternal sleep quality.

PROBLEM: Supplementation of breastfed babies is common during the hospital stay. BACKGROUND: The Baby Friendly Hospital Initiative (BFHI) optimises practices to support exclusive breastfeeding, yet supplementation is still prevalent. OBJECTIVE: To determine predictors for supplementation in a cohort of breastfed babies in a Baby-Friendly hospital. METHODS: Electronic hospital records of 1530 healthy term or near term singleton infants and their mothers were examined retrospectively and analysed to identify factors associated with in-hospital supplementation using Poisson regression (unadjusted and adjusted). FINDINGS: Fifteen percent of breastfed infants were supplemented during their hospital stay. Analysis by multivariable Poisson regression found that supplementation was independently associated with overweight (reference normal weight) (aRR [adjusted relative risk]=1.46; 95% CI: 1.11-1.93); primiparity (aRR=1.40; 95% CI: 1.09-1.80); early term gestation (37-376 weeks, aRR=2.79; 95% CI: 1.88-4.15; 38-386 weeks, aRR=2.03, 95%CI: 1.46-2.82); birthweight less than 2500 grams (reference 3000-3499 grams) (aRR=3.60; 95% CI: 2.32-5.60) and use of postpartum uterotonic (aRR=2.47; 95% CI: 1.09-5.55). Greater than 65 minutes of skin-to-skin contact at birth reduced the risk of supplementation (aRR=0.66; 95% CI; 0.48-0.92). CONCLUSION: These identified predictors for supplementation, can inform the development of interventions for mother-infant pairs antenatally or in the early postpartum period around increased breastfeeding education and support to reduce supplementation. It may also be possible to reduce supplementation through judicious use of postpartum uterotonics and facilitation of mother-infant skin-to-skin contact at birth for greater than one hour duration.

OBJECTIVE: To compare overnight oxygen saturation, heart rate and the thermal environment of infants sleeping in an indigenous sleep device (wahakura) or bassinet to identify potential risks and benefits. DESIGN: Randomised controlled trial. SETTING: Family homes in low socio-economic areas in New Zealand. PATIENTS: 200 mainly Maori mothers and their infants. INTERVENTIONS: Participants received a wahakura or bassinet from birth. MAIN OUTCOME MEASURES: Overnight oximetry, heart rate and temperature at 1 month. RESULTS: Intention-to-treat analysis for 83 bassinet and 84 wahakura infants showed no significant differences between groups for the mean time oxygen saturation (SpO2) was less than 94% (0.54 min, 95% CI -1.36 to 2.45) or less than 90% (0.22 min, 95% CI -0.56 to 1.00), the mean number of SpO2 dips per hour >5% (-0.19, 95% CI -3.07 to 2.69) or >10% (-0.41, 95% CI -1.63 to 0.81), mean heart rate (1.99 beats/min, 95% CI -1.02 to 4.99), or time shin temperature >36°C (risk ratio (RR): 0.63, 95% CI 0.13 to 2.99) or <34°C (RR: 0.89, 95% CI 0.61 to 1.30). A per-protocol analysis of 45 bassinet and 26 wahakura infants and an as-used analysis of 104 infants in a bassinet and 48 in a wahakura found no significant differences between groups for all outcome measures. CONCLUSIONS: This indigenous sleep device is at least as safe as the currently recommended bassinet, which supports its use as a sleep environment that offers an alternative way of bed-sharing.

OBJECTIVES: To compare an indigenous sleep device (wahakura) for infants at high risk for sudden unexpected death with a bassinet, for measures of infant sleep position, head covering, breastfeeding, bed-sharing, and maternal sleep and fatigue. METHODS: A total of 200 mainly Maori pregnant women were recruited from deprived areas of New Zealand. They were randomized to receive a bassinet or wahakura and asked to sleep the infant in this device from birth. Questionnaires at 1, 3, and 6 months and an overnight infrared video in the home at 1 month were completed. RESULTS: An intention-to-treat and an "as-used" analysis of questionnaires showed no group differences at 1, 3, and 6 months in infant-adult direct bed-sharing (7% vs 12%, P = .24 at 1 month), and at the 6-month interview, the wahakura group reported twice the level of full breastfeeding (22.5% vs 10.7%, P = .04). Maternal sleep and fatigue were not significantly different between groups. Video identified no increase in head covering, prone/side sleep position, or bed-sharing in the wahakura group, either from intention-to-treat analysis, or when analyzed for actual sleep location. CONCLUSION: There were no significant differences in infant risk behaviors in wahakura compared with bassinets and there were other advantages, including an increase in sustained breastfeeding. This suggests wahakura are relatively safe and can be promoted as an alternative to infant-adult bed-sharing. Policies that encourage utilization are likely to be helpful in high-risk populations.

BACKGROUND: Sudden Unexpected Death in Infancy (SUDI) has persistent high rates in deprived indigenous communities and much of this mortality is attributable to unsafe sleep environments. Whilst health promotion worldwide has concentrated on avoidance of bedsharing, the indigenous Maori community in New Zealand has reproduced a traditional flax bassinet (wahakura) designed to be used in ways that include bedsharing. To date there has been no assessment of the safety of this traditional sleeping device. METHODS/DESIGN: This two arm randomised controlled trial is being conducted with 200 mother-baby dyads recruited from Maori communities in areas of high deprivation in the Hawkes Bay, New Zealand. They are randomised to wahakura or bassinet use and investigation includes questionnaires at baseline (pregnancy), when baby is 1, 3, and 6 months, and an overnight video sleep study at 1 month with monitoring of baby temperature and oxygen saturation, and measurement of baby urinary cotinine and maternal salivary oxytocin. Outcome measures are amount of time head covered, amount of time in thermal comfort zone, number of hypoxic events, amount of time in the assigned sleep device, amount of time breastfeeding, number of parental (non-feed related) touching infant events, amount of time in the prone sleep position, the number of behavioural arousals and the amount of time infant is awake overnight. Survey data will compare breastfeeding patterns at 1, 3, and 6 months as well as data on maternal mind-mindedness, maternal wellbeing, attachment to baby, and maternal sleep patterns. DISCUSSION: Indigenous communities require creative SUDI interventions that fit within their prevailing world view. This trial, and its assessment of the safety of a wahakura relative to a standard bassinet, is an important contribution to the range of SUDI prevention research being undertaken worldwide.

OBJECTIVES: To identify desaturation events (arterial oxygen saturation [Sao(2)] <90%) and rebreathing events (inspired carbon dioxide (CO(2)) >3%), in bed-sharing (BS) versus cot-sleeping (CS) infants. METHODS: Forty healthy, term infants, aged 0 to 6 months who regularly bed-shared with at least 1 parent >5 hours per night and 40 age-matched CS infants were recruited. Overnight parent and infant behavior (via infrared video), Sao(2), inspired CO(2) around the infant's face, and body temperature were recorded during sleep at home. RESULTS: Desaturation events were more common in BS infants (risk ratio = 2.17 [95% confidence interval: 1.75 to 2.69]), associated partly with the warmer microenvironment during BS. More than 70% of desaturations in both groups were preceded by central apnea of 5 to 10 seconds with no accompanying bradycardia, usually in active sleep. Apnea >15 seconds was rare (BS infants: 3 events; CS infants: 6 events), as was desaturation <80% (BS infants: 3 events; CS infants: 4 events). Eighty episodes of rebreathing were identified from 22 BS infants and 1 CS infant, almost all preceded by head covering. During rebreathing, Sao(2) was maintained at the baseline of 97.6%. CONCLUSIONS: BS infants experienced more oxygen desaturations preceded by central apnea, partly related to the warmer microenvironment. Rebreathing occurred mainly during bed-sharing. Infants were at low risk of sudden infant death syndrome and maintained normal oxygenation. The effect of repeated exposure to oxygen desaturation in vulnerable infants is unknown as is the ability of vulnerable infants to respond effectively to rebreathing caused by head covering.

BACKGROUND: Primary postpartum hemorrhage is a leading cause of maternal mortality and morbidity internationally. Research comparing physiological (expectant) and active management of the third stage of labor favors active management, although studies to date have focused on childbirth within hospital settings, and the skill levels of birth attendants in facilitating physiological third stage of labor have been questioned. The aim of this study was to investigate the effect of place of birth on the risk of postpartum hemorrhage and the effect of mode of management of the third stage of labor on severe postpartum hemorrhage. METHODS: Data for 16,210 low-risk women giving birth in 2006 and 2007 were extracted from the New Zealand College of Midwives research database. Modes of third stage management and volume of blood lost were compared with results adjusted for age, parity, ethnicity, smoking, length of labor, mode of birth, episiotomy, perineal trauma, and newborn birthweight greater than 4,000 g. RESULTS: In total, 1.32 percent of this low-risk cohort experienced an estimated blood loss greater than 1,000 mL. Place of birth was not found to be associated with risk of blood loss greater than 1,000 mL. More women experienced blood loss greater than 1,000 mL in the active management of labor group for all planned birth places. In this low-risk cohort, those women receiving active management of third stage of labor had a twofold risk (RR: 2.12, 95% CI: 1.39-3.22) of losing more than 1,000 mL blood compared with those expelling their placenta physiologically. CONCLUSIONS: Planned place of birth does not influence the risk of blood loss greater than 1,000 mL. In this low-risk group active management of labor was associated with a twofold increase in blood loss greater than 1,000 mL compared with physiological management. (BIRTH 39:2 June 2012).

BACKGROUND: Midwives providing care as lead maternity caregivers in New Zealand provide continuity of care to women who may give birth in a variety of settings, including home, primary units, and secondary and tertiary level hospitals. The purpose of this study was to compare mode of birth and intrapartum intervention rates for low-risk women planning to give birth in these settings under the care of midwives. METHODS: Data for a cohort of low-risk women giving birth in 2006 and 2007 were extracted from the Midwifery Maternity Provider Organisation database. Mode of birth, intrapartum interventions, and neonatal outcomes were compared with results adjusted for age, parity, ethnicity, and smoking. RESULTS: Women planning to give birth in secondary and tertiary hospitals had a higher risk of cesarean section, assisted modes of birth, and intrapartum interventions than similar women planning to give birth at home and in primary units. The risk of emergency cesarean section for women planning to give birth in a tertiary unit was 4.62 (95% CI: 3.66-5.84) times that of a woman planning to give birth in a primary unit. Newborns of women planning to give birth in secondary and tertiary hospitals also had a higher risk of admission to a neonatal intensive care unit (RR: 1.40, 95% CI: 1.05-1.87; RR: 1.78, 95% CI: 1.31-2.42) than women planning to give birth in a primary unit. CONCLUSIONS: Planned place of birth has a significant influence on mode of birth and rates of intrapartum intervention in childbirth.

OBJECTIVES: We aimed to provide a quantitative analysis of the sleep arrangements and behaviors of bed-sharing families to further understand the risks and benefits as well as the effects of infant age and room temperature on bed-sharing behaviors. METHODS: Forty infants who regularly bed shared with > or = 1 parent > or = 5 hours per night were recruited. Overnight video of the family and physiological monitoring of the infant was conducted in infants' homes. Infant sleep position, potential for exposure to expired air, head covering and uncovering, breastfeeding, movements, family sleep arrangements, responses to the infant, and interactions were logged. RESULTS: All infants slept with their mother. Fathers were included in 18 studies and siblings in 4. Infants usually slept beside the mother, separated from the father/siblings (if present), facing the mother, with head at mothers' breast level, touching, or with mother cradling. Median overnight breastfeeding duration was 40.5 minutes. Mothers commonly faced their infant, but infants were rarely in a position that potentially exposed them to maternal expired air. Fathers were seldom in contact with the infant during sleep. Of the 102 head-covering episodes observed in 22 infants, 80% were because of changes in adult sleep position. Sixty-eight percent of head uncovering was facilitated by the mother; half of these events were prompted by the infant. A 1 degree C increase in room temperature decreased infant head covering by 0.2 hours. CONCLUSIONS: The mother-infant relationship is of prime importance during bed sharing, whether the father is present or not. The focus around breastfeeding often dictates the sleep position of the infant and mother, though room temperature may also influence this. In colder rooms infants tend to spend more time with their face covered by bedding. Frequent maternal interactions rely on the ability of the mother to arouse with little stimulation. Mothers, perhaps impaired by alcohol, smoking, or overtiredness, may not be able to respond appropriately.

OBJECTIVES: To observe the behavior of infants sleeping in the natural physical environment of home, comparing the 2 different sleep practices of bed sharing and cot sleeping quantifying to factors that have been identified as potential risks or benefits. METHODS: Forty routine bed-sharing infants, aged 5-27 weeks were matched for age and season of study with 40 routine cot-sleeping infants. Overnight video and physiologic data of bed-share infants and cot-sleep infants were recorded in the infants' own homes. Sleep time, sleep position, movements, feeding, blanket height, parental checks, and time out of the bed or cot were logged. RESULTS: The total sleep time was similar in both groups (bed-sharing median: 8.6 hours; cot-sleeping median: 8.2 hours). Bed-sharing infants spent most time in the side position (median: 5.7 hours, 66% of sleep time) and most commonly woke at the end of sleep in this position, whereas cot-sleeping infants most commonly slept supine (median: 7.5 hours, 100%) and woke at the end of sleep in the supine position. Prone sleep was uncommon in both groups. Head covering above the eyes occurred in 22 bed-sharing infants and 1 cot-sleeping infant. Five of these bed-sharing infants were head covered at final waking time, but the cot-sleeping infant was not. Bed-sharing parents looked at or touched their infant more often (median: 11 vs 4 times per night) but did not always fully wake to do so. Movement episodes were shorter in the bed-sharing group as was total movement time (37 vs 50 minutes respectively), whereas feeding was 3.7 times more frequent in the bed-sharing group than the cot-sleeping group. CONCLUSIONS: Bed-share infants without known risk factors for sudden infant death syndrome (SIDS) experience increased maternal touching and looking, increased breastfeeding, and faster and more frequent maternal responses. This high level of interaction is unlikely to occur if maternal arousal is impaired, for example, by alcohol or overtiredness. Increased head covering and side sleep position occur during bed-sharing, but whether these factors increase the risk of SIDS, as they do in cot sleeping, requires further investigation.
