Short-term effects of early suckling and touch of the nipple on maternal behaviour

Impact of Early Bonding During the Maternal Sensitive Period on Long-Term Effects: A Systematic Review

This research project examines the long-term effects of maternal-neonatal bonding during a mother's "sensitive period." The review explores how early contact between a mother and her newborn can affect their psychosocial and emotional well-being in the future. Within an hour after birth, oxytocin levels increase for mothers, while catecholamine surges enhance neonates' memory retention to encourage immediate skin-to-skin contact (SSC), which promotes breastfeeding with benefits, such as quicker placenta expulsion, less bleeding, and lower stress. As per sources to date, there is no systematic review on this subject; however, numerous studies exist regarding short-term outcomes, exclusive breastfeeding, and childhood problems. The exploration involves rigorous searches of academic databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for transparency and reproducibility by using the Population, Intervention, Comparison, and Outcome (PICO) framework. Of the 516 initially identified articles, only five were relevant based on refined selection criteria, making it clear from the analysis that sensitive-period bonding produces long-term impacts in infants. Few studies are available, particularly in recent years; thus, more research is required in this area.

Breastfeeding and infant care as 'sexed' care work: reconsideration of the three Rs to enable women's rights, economic empowerment, nutrition and health

Women's lifelong health and nutrition status is intricately related to their reproductive history, including the number and spacing of their pregnancies and births, and for how long and how intensively they breastfeed their children. In turn, women's reproductive biology is closely linked to their social roles and situation, including regarding economic disadvantage and disproportionate unpaid work. Recognizing, as well as reducing and redistributing women's care and domestic work (known as the 'Three Rs'), is an established framework for addressing women's inequitable unpaid care work. However, the care work of breastfeeding presents a dilemma, and is even a divisive issue, for advocates of women's empowerment, because reducing breastfeeding and replacing it with commercial milk formula risks harming women's and children's health. It is therefore necessary for the interaction between women's reproductive biology and infant care role to be recognized in order to support women's human rights and enable governments to implement economic, employment and other policies to empower women. In this paper, we argue that breastfeeding-like childbirth-is reproductive work that should not be reduced and cannot sensibly be directly redistributed to fathers or others. Rather, we contend that the Three Rs agenda should be reconceptualized to isolate breastfeeding as 'sexed' care work that should be supported rather than reduced with action taken to avoid undermining breastfeeding. This means that initiatives toward gender equality should be assessed against their impact on women's ability to breastfeed. With this reconceptualization, adjustments are also needed to key global economic institutions and national statistical systems to appropriately recognize the value of this work. Additional structural supports such as maternity protection and childcare are needed to ensure that childbearing and breastfeeding do not disadvantage women amidst efforts to reduce gender pay gaps and gender economic inequality. Distinct policy interventions are also required to facilitate fathers' engagement in enabling and supporting breastfeeding through sharing the other unpaid care work associated with parents' time-consuming care responsibilities, for both infants and young children and related household work.

Mental Health Benefits of Breastfeeding: A Literature Review

Pregnancy is typically viewed as a time of emotional well-being for prospective mothers, but for some, this period can negatively impact mental health. However, the relationship between postpartum mental health and breastfeeding is not clearly understood. Considering that many health authorities recommend breastfeeding, clearly defining this relationship is important. This review aims to illustrate the effects that breastfeeding has on the mental health of postpartum mothers. An extensive computerized search was performed through databases of PubMed, CINAHL, and Medline. All studies conducted to determine the effects of breastfeeding on mental health were screened and included in this review. Search terms related to breastfeeding, postpartum, and mental health were used. This review on breastfeeding and postpartum depression (PPD) begins by discussing the correlation between lactation and the maternal stress response. Another component discussed is the duration of breastfeeding and its importance in limiting PPD symptoms. The review then shifts to focus more on the psychological aspects of breastfeeding, notably on changes to the sleep-wake cycle and mother-infant interactions. The final part of the review emphasizes the danger that early breastfeeding cessation imposes on a mother’s mental health, portraying how prenatal and early-onset postpartum depression may lead to early breastfeeding cessation. This composite collection of studies clarifies the importance of breastfeeding in reducing the incidence and severity of maternal postpartum depression.

Breastfeeding patterns and factors associated with early weaning in the Western Amazon

OBJECTIVE

To characterize breastfeeding patterns in the first six months of life and factors associated with early weaning in a birth-cohort in Rio Branco, state of Acre.

METHODS

This is a prospective study with all babies born between April and June 2015. The mothers were interviewed soon after birth and between 6 and 15 months postpartum. At hospital discharge, breastfeeding was defined as exclusively (EBF), and breastfeeding (BF). In the follow-up, breastfeeding patterns were exclusive breastfeeding (EBF), predominant breastfeeding (PBF), and breastfeeding (BF). The interruption of breastfeeding in the first six months was classified as early weaning. The Kaplan Meier method (log-rank: 95%) was used to estimate the conditional probability of change in breastfeeding pattern, and early weaning risk. Crude and adjusted proportional Cox regression models, and their respective 95% confidence intervals (95%CI), were used to analyze the factors associated with early weaning.

RESULTS

The study included 833 infants in EBF (95.4%) and BF (4.6%) at hospital discharge. During the first six months of life, the infant likely discharged in EBF remaining in EBF, becoming PBF, and BF, were respectively 16.4%, 32.3%, and 56.5%. The weaning likely at six months was statistically higher for infants discharged in BF (47.4%) when compared with those discharged in EBF (26%). Factors associated with early weaning were BF at hospital discharge (HR = 1.82; 95%CI 1.06-3.11), no mother cross-breastfeeding (HR = 2.50; 95%CI 1.59-3.94), pacifier use (HR = 6.23; 95%CI 4.52-8.60), less than six months of breastfeeding intention (HR = 1.93; 95%CI 1.25-2.98), lack of breastfeeding in the first hour of life (HR = 1.45; 95%CI 1.10-1.92), and pregnancy alcohol consumption (HR = 1.88; 95%CI 1.34-2.90).

CONCLUSION

Compared to infants in EBF, those in BF at hospital discharge were more likely to wean. Public health efforts should prioritize EBF at hospital discharge, promote breastfeeding in the first hour of life, and prevent alcohol consumption risks during pregnancy, cross-breastfeeding and pacifier use.

Effect of Community-Initiated Kangaroo Mother Care on Postpartum Depressive Symptoms and Stress Among Mothers of Low-Birth-Weight Infants: A Randomized Clinical Trial

IMPORTANCE

Approximately 1 in 5 women in low- and middle-income countries experience postpartum depression, and the risk is higher among mothers of low-birth-weight (LBW) infants. Kangaroo mother care (KMC) is effective in improving survival among LBW infants, but the benefits of KMC for mothers are not well described.

OBJECTIVE

To estimate the effects of community-initiated KMC (ciKMC) on maternal risk of moderate-to-severe postpartum depressive symptoms and on salivary cortisol concentration, a biomarker of stress.

DESIGN, SETTING, AND PARTICIPANTS

This was an unmasked, parallel-group, individually randomized clinical trial. Participants included 1950 mothers of stable LBW infants (weighing 1500-2250 g) in rural and semiurban low-income populations in North India enrolled between April 2017 and March 2018. Data analysis was performed from January to July 2020.

INTERVENTIONS

Eligible participants were randomly assigned to the intervention or control group by block randomization. The mothers in the intervention group were supported to practice ciKMC until 28 days after birth or until the infant wriggled out of the KMC position (ie, was no longer staying in the KMC position). The intervention included promotion and support of skin-to-skin contact and exclusive breastfeeding through home visits.

MAIN OUTCOMES AND MEASURES

Postpartum depressive symptoms at the end of the neonatal period were measured using the Patient Health Questionnaire-9, with a score of 10 or higher used to identify moderate-to-severe depressive symptoms. Salivary cortisol concentration was measured in a subsample of 550 mothers before and after breastfeeding on day 28 after birth.

RESULTS

Of the 1950 participants (mean [SD] age, 23 [3.5] years), outcome assessment was completed for 974 of 1047 participants (93%) in the intervention group and 852 of 903 participants (94%) in the control group. Sixty-four percent of participants (1175 of 1826 participants) belonged to the lowest 3 wealth quintiles. The proportion of mothers with moderate-to-severe postpartum depressive symptoms was 10.8% (95% CI, 8.9%-12.9%; 105 of 974 mothers) in the intervention group vs 13.6% (95% CI, 11.4%-16.1%; 116 of 852 mothers) in the control group. The adjusted relative risk of moderate-to-severe maternal postpartum depressive symptoms was 0.75 (95% CI, 0.59-0.96), or an efficacy of 25%. There was no difference in day-28 salivary cortisol concentration between the ciKMC and control group mothers before or after breastfeeding. The analysis estimated that supporting 36 mothers to perform KMC at home would prevent 1 mother from experiencing moderate-to-severe postpartum depressive symptoms.

CONCLUSIONS AND RELEVANCE

These findings suggest that ciKMC practice may substantially reduce the risk of moderate-to-severe maternal postpartum depressive symptoms. This evidence supports KMC as an intervention to be incorporated in essential newborn care programs in low- and middle-income settings.

Breastfeeding in the First Hours of Life Protects Against Pacifier Use: A Birth Cohort Study

Objective: To investigate risk factors for pacifier use in the first year of life. Materials and Methods: A prospective cohort study was conducted with children enrolled at birth in Porto Alegre, Southern Brazil, whose mothers underwent prenatal care at primary care units. Soon after the birth of the children, data were collected on anthropometrics, type of childbirth, and time until breastfeeding on the first day of life. At 6 and 12 months of age, data were collected on breastfeeding practices and whether the child had used a pacifier in the previous 6 months. Statistical analysis involved the use of Poisson regression with robust variance. Results: The incidence of pacifier use in the first year of life was 60% (317/532). The multivariable analysis showed that pacifier use in the first year of life was 33% higher when the mother was younger than 18 years of age (relative risk [RR] = 1.33; confidence interval [95% CI]: 1.01-1.76). Infants who breastfed in the first 30 minutes after birth had a 25% lower risk of pacifier use in the first year of life (RR = 0.75; 95% CI: 0.60-0.94), and those who breastfed between 30 minutes and 6 hours after birth had an 18% lower risk (RR = 0.82; 95% CI: 0.69-0.97) compared to those who took longer to begin breastfeeding or did not breastfeed. Conclusions for Practice: Breastfeeding soon after being born protected against pacifier use in the first year of life. This finding suggests pathways to improve child health, especially in the prenatal period and with an emphasis on pregnant adolescents.

Relative effects of breastfeeding intention and practice on maternal responsiveness

Our objective was to examine the differential effects of antenatal breastfeeding intention (BI) and breastfeeding practice (BP) on maternal postnatal responsiveness. We conducted a secondary analysis of longitudinal data from a subsample of 962 mother-infant dyads from a U.K.-based birth cohort study the Avon Longitudinal Study of Parents and Children. Exposures were BI and BPs measured at 32 weeks of gestation and 18 months' postpartum. The outcome was maternal responsiveness assessed at 12 months' postpartum. We used logistic regression analyses unadjusted and adjusted for confounders. Intention to breastfeed was associated with increased odds of postnatal maternal responsiveness independent of BP, adjusted odds ratio (OR) = 2.34, 95% CI [1.42, 3.86]. There was no evidence that BP was an independent predictor of maternal responsiveness, OR = 0.93, 95% CI [0.55, 1.57]. Life-course epidemiology analyses demonstrated that maternal responsiveness is most positive when both BI and BP are present. This is the first population-based study to provide evidence that BI during pregnancy is more strongly associated with maternal postnatal responsiveness than is BP. Further research is needed to understand the determinants of BI in pregnancy and its relationships with maternal responsiveness.

Skin-to-skin contact the first hour after birth, underlying implications and clinical practice

AIM

This paper integrates clinical expertise to earlier research about the behaviours of the healthy, alert, full-term infant placed skin-to-skin with the mother during the first hour after birth following a noninstrumental vaginal birth.

METHOD

This state-of-the-art article forms a link within the knowledge-to-action cycle, integrating clinical observations and practice with evidence-based findings to guide clinicians in their work to implement safe uninterrupted skin-to-skin contact the first hours after birth.

RESULTS

Strong scientific research exists about the importance of skin-to-skin in the first hour after birth. This unique time for both mother and infant, individually and in relation to each other, provides vital advantages to short- and long-term health, regulation and bonding. However, worldwide, clinical practice lags. A deeper understanding of the implications for clinical practice, through review of the scientific research, has been integrated with enhanced understanding of the infant's instinctive behaviour and maternal responses while in skin-to-skin contact.

CONCLUSION

The first hour after birth is a sensitive period for both the infant and the mother. Through an enhanced understanding of the newborn infant's instinctive behaviour, practical, evidence-informed suggestions strive to overcome barriers and facilitate enablers of knowledge translation. This time must be protected by evidence-based routines of staff.

Sustained Breastfeeding, Complementation, and Care

Breastfeeding can enhance care of infants. In most cultures there is an age after which breastfeeding is no longer considered socially acceptable. In Western countries, shorter periods have long been the norm. Researchers may underestimate how common sustained breastfeeding is in both industrialized and low-income settings. Little is known about the contributions breastfeeding may make to the emotional and physical health of mothers and infants when sustained for longer periods. It clearly offers economic and certain nutritional advantages, such as preventing severe vitamin A deficiency, and it reduces fertility. Sustained breastfeeding is often associated with slower child growth. This is probably not often a unidimensional causal relationship. Part of the explanation may be that sustained breastfeeding increases infant survival under extreme conditions of poverty and food insecurity.

The duration of breastfeeding, especially exclusive breastfeeding, may have decreased in some areas in recent decades due to inappropriate messages from health workers, in part due to a lack of careful definitions. A schematic figure depicts four separate processes, each referred to at times as “weaning.” To reduce the incidence of early cessation of breastfeeding, it is important to separate the “complementation” and “replacement” components.

Modernization processes such as urbanization can occur so rapidly that new ideas for achieving infant care goals may be needed. However, in relatively stable resource-poor settings, care strategies such as sustained breastfeeding are likely to be well adapted, and outsiders would be wise to focus on protecting them. Indeed, breastfeeding programmes should place priority on protection (marketing codes) and support (breastfeeding-friendly practices at delivery and support measures for women in the market labour force) before promotion (mass media).

Breastfeeding as the Foundation of Care

Breastfeeding, which unites food, health, and care, enhances the child's abilities to elicit good care through superior attachment, rhythmic synchrony, and vision and brain development. Parental responsiveness is increased by bonding, child spacing, and time with the baby Breastfeeding and other forms of care for nutrition share the aspects of interaction, cultural mediation, erosion of traditions, endemic misinformation, small-scale decision-making, and vulnerability to institutional mismanagement. Breastfeeding differs in requiring continuity of the caretaker and in facing social and profit-motivated opposition. Research is needed on adequate care for siblings, effective help for high-risk infants, improved duration, and nutrition of both mother and child in the second year of breastfeeding Despite effective strategies, such as the baby-friendly hospital initiative and community support groups, the challenge remains to move from motivating women to ensuring access to practical and confidence-building support.

The Role of Paternity Acknowledgment in Breastfeeding Noninitiation

BACKGROUND

In the United States, less than a quarter of mothers breastfeed in accordance with national recommendations. To date, researchers have demonstrated that paternal support directly influences breastfeeding outcomes; however, healthcare practitioners may not be able to quantify a lack of support in the immediate postpartum period. Research aim: The aim is to investigate the relationship between breastfeeding noninitiation and paternity acknowledgment, a factor that can be easily identified in the immediate postpartum period.

METHODS

Data from the 2014 Vital Statistics Natality Birth database were analyzed. Analysis included primiparous singleton births with no health complications ( N = 1,127,861). Based on the birth certificate data, paternity acknowledgment was categorized as married with paternity acknowledged, unmarried with paternity acknowledged, and unmarried without paternity acknowledged. Breastfeeding initiation was dichotomized (yes or no). Multiple logistic regression analyses were conducted to obtain crude and adjusted odds ratios and 99% confidence intervals (α = .01).

RESULTS

Approximately one in seven births had no paternity acknowledgment on their birth certificate. After adjusting for confounders, mothers who were not married but the paternity of the infant was acknowledged had 50% higher odds of breastfeeding noninitiation compared with mothers who were married and their infants' paternity was acknowledged (adjusted odds ratio = 1.50, 99% confidence interval [1.47, 1.53]). Furthermore, women who were unmarried and without paternity acknowledgment had 135% higher odds of breastfeeding noninitiation compared with married women with paternity acknowledgment (adjusted odds ratio = 2.35, 99% confidence interval [2.30, 2.41]).

CONCLUSION

Women whose births were not acknowledged by the fathers may need additional breastfeeding support from healthcare practitioners.

Management of healthy newborns in the delivery room and maternal satisfaction

INTRODUCTION

The first exchanges between a newborn baby and its mother are essential. Any separation can have negative effects on the establishment of the first connections as well as breastfeeding.

OBJECTIVE

To establish the current state of management of healthy newborn babies in the delivery room and assess the reasons for possible separation and the feelings of mothers facing this separation.

MATERIALS AND METHODS

Observational descriptive single-center study, made up of two parts: 1/a questionnaire given to the mothers, postpartum; 2/the collection of data concerning the transfer of healthy newborn babies to the nursery.

RESULTS

The study took place over a period of 8 weeks. Eighty-five mothers were interviewed. Seventy-two percent of the newborn babies left the delivery room during the first 2h of life. For 67 %, the duration of skin-to-skin contact was less than 1h. For 49 %, the main reason was the performance of routine care. The mothers were satisfied with the care provided in the delivery room.

CONCLUSION

Too many healthy newborn babies are separated from their mothers during the first 2h of life, mainly for routine care. Skin-to-skin contact must be part of the physiological reception of newborn babies in the delivery room. The medical staff and parents must be informed of this aspect and its beneficial effects. It is necessary to reconsider the organization of practices to propose a management system that promotes the establishment of a strong mother-child bond.

Care Through the Newborn's Eyes

Separation of mothers and infants after birth is standard practice for many hospitals, yet not evidence-based. Nonseparation clearly has numerous benefits. However, newborns lack a voice to make choices to direct their course of care. The evidence supports nonseparation strategies for mothers and infants that promote attachment, physiologic regulation, nutrition, sleep, communication, and management of stress/pain. Moreover, the evidence is compelling that nonseparation is essential. The time has come to act on the evidence and begin seeing the care we provide through the newborn's eyes.

A temperature gradient may support mother-infant thermal identification and communication in the breast crawl from birth to breastfeeding

AIM

The human female's nipple-areolar complex (NAC) is the point of arrival of a natural progression from birth to breastfeeding, linked to functional, chemical and biophysical cues that promote the breast crawl soon after birth. We investigated the thermal gradient generated by the lips of the neonate and warmth of the NAC, which may drive the infant directly to the nipple.

METHODS

We prospectively studied 41 full-term singleton infants and their mothers at the Policlinico Abano Terme, Italy, between January 1, 2015, and February 28, 2015. NAC and breast quadrant temperatures were assessed 6 ± 2 hours prepartum and one and two days postpartum, together with the neonates' lip temperature.

RESULTS

The temperature of the neonates' lips was significantly lower than the forehead temperature on days one and two postpartum (delta = -1.24°C, p < 0.001 and delta = -1.02°C, p < 0.001, respectively). Thus, the thermal gradient between the NAC and the neonates' lips was -1.66 ± 1.07°C on day one (p < 0.001) and -1.68 ± 0.63°C (p < 0.001) on day two postpartum.

CONCLUSION

These findings demonstrate, for the first time, that a temperature gradient may support mother-infant thermal identification and communication in the breast crawl and in the natural progression of the continuum from birth to breastfeeding.

Early skin-to-skin contact for mothers and their healthy newborn infants

BACKGROUND

Mother-infant separation post birth is common. In standard hospital care, newborn infants are held wrapped or dressed in their mother's arms, placed in open cribs or under radiant warmers. Skin-to-skin contact (SSC) begins ideally at birth and should last continually until the end of the first breastfeeding. SSC involves placing the dried, naked baby prone on the mother's bare chest, often covered with a warm blanket. According to mammalian neuroscience, the intimate contact inherent in this place (habitat) evokes neuro-behaviors ensuring fulfillment of basic biological needs. This time frame immediately post birth may represent a 'sensitive period' for programming future physiology and behavior.

OBJECTIVES

To assess the effects of immediate or early SSC for healthy newborn infants compared to standard contact on establishment and maintenance of breastfeeding and infant physiology.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (17 December 2015), made personal contact with trialists, consulted the bibliography on kangaroo mother care (KMC) maintained by Dr Susan Ludington, and reviewed reference lists of retrieved studies.

SELECTION CRITERIA

Randomized controlled trials that compared immediate or early SSC with usual hospital care.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Quality of the evidence was assessed using the GRADE approach.

MAIN RESULTS

We included 46 trials with 3850 women and their infants; 38 trials with 3472 women and infants contributed data to our analyses. Trials took place in 21 countries, and most recruited small samples (just 12 trials randomized more than 100 women). Eight trials included women who had SSC after cesarean birth. All infants recruited to trials were healthy, and the majority were full term. Six trials studied late preterm infants (greater than 35 weeks' gestation). No included trial met all criteria for good quality with respect to methodology and reporting; no trial was successfully blinded, and all analyses were imprecise due to small sample size. Many analyses had statistical heterogeneity due to considerable differences between SSC and standard care control groups. Results for womenSSC women were more likely than women with standard contact to be breastfeeding at one to four months post birth, though there was some uncertainty in this estimate due to risks of bias in included trials (average risk ratio (RR) 1.24, 95% confidence interval (CI) 1.07 to 1.43; participants = 887; studies = 14; I² = 41%; GRADE: moderate quality). SSC women also breast fed their infants longer, though data were limited (mean difference (MD) 64 days, 95% CI 37.96 to 89.50; participants = 264; studies = six; GRADE:low quality); this result was from a sensitivity analysis excluding one trial contributing all of the heterogeneity in the primary analysis. SSC women were probably more likely to exclusively breast feed from hospital discharge to one month post birth and from six weeks to six months post birth, though both analyses had substantial heterogeneity (from discharge average RR 1.30, 95% CI 1.12 to 1.49; participants = 711; studies = six; I² = 44%; GRADE: moderate quality; from six weeks average RR 1.50, 95% CI 1.18 to 1.90; participants = 640; studies = seven; I² = 62%; GRADE: moderate quality).Women in the SCC group had higher mean scores for breastfeeding effectiveness, with moderate heterogeneity (IBFAT (Infant Breastfeeding Assessment Tool) score MD 2.28, 95% CI 1.41 to 3.15; participants = 384; studies = four; I² = 41%). SSC infants were more likely to breast feed successfully during their first feed, with high heterogeneity (average RR 1.32, 95% CI 1.04 to 1.67; participants = 575; studies = five; I² = 85%). Results for infantsSSC infants had higher SCRIP (stability of the cardio-respiratory system) scores overall, suggesting better stabilization on three physiological parameters. However, there were few infants, and the clinical significance of the test was unclear because trialists reported averages of multiple time points (standardized mean difference (SMD) 1.24, 95% CI 0.76 to 1.72; participants = 81; studies = two; GRADE low quality). SSC infants had higher blood glucose levels (MD 10.49, 95% CI 8.39 to 12.59; participants = 144; studies = three; GRADE: low quality), but similar temperature to infants in standard care (MD 0.30 degree Celcius (°C) 95% CI 0.13 °C to 0.47 °C; participants = 558; studies = six; I² = 88%; GRADE: low quality). Women and infants after cesarean birthWomen practicing SSC after cesarean birth were probably more likely to breast feed one to four months post birth and to breast feed successfully (IBFAT score), but analyses were based on just two trials and few women. Evidence was insufficient to determine whether SSC could improve breastfeeding at other times after cesarean. Single trials contributed to infant respiratory rate, maternal pain and maternal state anxiety with no power to detect group differences. SubgroupsWe found no differences for any outcome when we compared times of initiation (immediate less than 10 minutes post birth versus early 10 minutes or more post birth) or lengths of contact time (60 minutes or less contact versus more than 60 minutes contact).

AUTHORS' CONCLUSIONS

Evidence supports the use of SSC to promote breastfeeding. Studies with larger sample sizes are necessary to confirm physiological benefit for infants during transition to extra-uterine life and to establish possible dose-response effects and optimal initiation time. Methodological quality of trials remains problematic, and small trials reporting different outcomes with different scales and limited data limit our confidence in the benefits of SSC for infants. Our review included only healthy infants, which limits the range of physiological parameters observed and makes their interpretation difficult.

The Association Between Common Labor Drugs and Suckling When Skin-to-Skin During the First Hour After Birth

BACKGROUND

Intrapartum drugs, including fentanyl administered via epidural and synthetic oxytocin, have been previously studied in relation to neonatal outcomes, especially breastfeeding, with conflicting results. We examined the normal neonatal behavior of suckling within the first hour after a vaginal birth while in skin-to-skin contact with mother in relation to these commonly used drugs. Suckling in the first hour after birth has been shown in other studies to increase desirable breastfeeding outcomes.

METHOD

Prospective comparative design. Sixty-three low-risk mothers self-selected to labor with intrapartum analgesia/anesthesia or not. Video recordings of infants during the first hour after birth while being held skin-to-skin with their mother were coded and analyzed to ascertain whether or not they achieved Stage 8 (suckling) of Widström's 9 Stages of newborn behavior during the first hour after birth.

RESULTS

A strong inverse correlation was found between the amount and duration of exposure to epidural fentanyl and the amount of synthetic oxytocin against the likelihood of achieving suckling during the first hour after a vaginal birth.

CONCLUSIONS

Results suggest that intrapartum exposure to the drugs fentanyl and synthetic oxytocin significantly decreased the likelihood of the baby suckling while skin-to-skin with its mother during the first hour after birth.

Fatores associados ao início tardio da amamentação em hospitais do Sistema Único de Saúde no Município do Rio de Janeiro, Brasil, 2009

Resumo O objetivo do trabalho foi analisar os fatores associados com o início tardio da amamentação (não amamentar na primeira hora de vida). Estudo transversal conduzido em 2009 com 673 puérperas internadas em hospitais do Sistema Único de Saúde (SUS) do Município do Rio de Janeiro, Brasil. Um modelo de regressão logística multinível com dois níveis (individual e hospitalar) foi utilizado nas análises estatísticas. A prevalência de início tardio da amamentação foi de 49,2%. O parto em Hospital Amigo da Criança (HAC) teve um efeito protetor contra o atraso no início da amamentação (OR = 0,17; IC95%: 0,05-0,55), enquanto a cesariana (OR = 5,95; IC95%: 3,88-9,12) e o desconhecimento do resultado do exame anti-HIV até o parto (OR = 2,16; IC95%: 1,04-4,50) aumentaram a chance de atraso. Redução das taxas de cesariana, adesão aos protocolos de atenção pré-natal e ampliação do credenciamento dos hospitais como HAC são estratégias importantes para promover o aleitamento materno na primeira hora de vida.

Lack of Breastfeeding: A Potential Risk Factor in the Multifactorial Genesis of Borderline Personality Disorder and Impaired Maternal Bonding

Borderline personality disorder (BPD) is characterized by a pattern of intense but unstable interpersonal relationships. These interpersonal dysfunctions may originate from impaired bonding and attachment that is determined during early life. Remarkably, it has been reported that the quality of mother-infant relationship is influenced by the feeding mode. Thus, bottle feeding instead of breastfeeding and possible lack of maternal bonding-related behavior may increase the risk for later psychopathology and attachment problems as seen in BPD. A total of 100 BPD patients and 100 matched healthy controls underwent semistructured interviews, based on retrospective information about early risk factors and breastfeeding during infancy. The authors' analyses revealed that BPD patients were significantly less breastfed compared to healthy controls (no breastfeeding in BPD: 42.4%; no breastfeeding in controls: 18.2%; p < .001). The BPD diagnosis was significantly predicted by the variable "no breastfeeding" (p < .001; odds ratio [OR] = 3.32; confidence interval [CI] [1.74, 6.34]), even after adjustment for childhood trauma and several confounding factors (p = .001). The variable "no breastfeeding" accounts for 9.1% of the variance of the BPD diagnosis and is associated with low perceived maternal bonding (p = .006). Breastfeeding may act as an early indicator of the mother-infant relationship that seems to be relevant for bonding and attachment later in life.

Determinants of early initiation of breastfeeding in rural Tanzania

BACKGROUND

Breastfeeding is widely known for its imperative contribution in improving maternal and newborn health outcomes. However, evidence regarding timing of initiation of breastfeeding is limited in Tanzania. This study examines the extent of and factors associated with early initiation of breastfeeding in three rural districts of Tanzania.

METHODS

Data were collected in 2011 in a cross-sectional survey of random households in Rufiji, Kilombero and Ulanga districts of Tanzania. From the survey, 889 women who had given birth within 2 years preceding the survey were analyzed. Both descriptive and inferential statistical analyses were conducted. Associations between the outcome variable and each of the independent variables were tested using chi-square. Logistic regression was used for multivariate analysis.

RESULTS

Early initiation of breastfeeding (i.e. breastfeeding initiation within 1 h of birth) stood at 51 %. The odds of early initiation of breastfeeding was significantly 78 % lower following childbirth by caesarean section than vaginal birth (adjusted odds ratio (OR) = 0.22; 95 % confidence interval (CI) 0.14, 0.36). However, this was almost twice as high for women who gave birth in health facilities as for those who gave birth at home (OR = 1.75; 95 % CI 1.25, 2.45). Furthermore, maternal knowledge of newborn danger signs was negatively associated with early initiation of breastfeeding (moderate vs. high: OR = 1.73; 95 % CI 1.23, 2.42; low vs. high: OR = 2.06; 95 % CI 1.43, 2.96). The study found also that early initiation of breastfeeding was less likely in Rufiji compared to Kilombero (OR = 0.52; 95 % CI 0.31, 0.89), as well as among ever married than currently married women (OR = 0.46; 95 % CI 0.25, 0.87).

CONCLUSIONS

To enhance early initiation of breastfeeding, using health facilities for childbirth must be emphasized and facilitated among women in rural Tanzania. Further, interventions to promote and enforce early initiation of breastfeeding should be devised especially for caesarean births. Women residing in rural locations and women who are not currently married should be specifically targeted with interventions aimed at enhancing early initiation of breastfeeding to ensure healthy outcomes for newborns.

The higher temperature in the areola supports the natural progression of the birth to breastfeeding continuum

Numerous functional features that promote the natural progression of the birth to breastfeeding continuum are concentrated in the human female's areolar region. The aim of this study was to look more closely into the thermal characteristics of areola, which are said to regulate the local evaporation rate of odors and chemical signals that are uniquely important for the neonate's 'breast crawl'. A dermatological study of the areolae and corresponding intern breast quadrants was undertaken on the mothers of 70 consecutive, healthy, full-term breastfed infants. The study took place just after the births at the Policlinico Abano Terme, in Italy from January to February 2014. Temperature, pH and elasticity were assessed one day postpartum using the Soft Plus 5.5 (Callegari S.P.A., Parma, Italy). The mean areolar temperature was found to be significantly higher than the corresponding breast quadrant (34.60 ±1.40°C vs. 34.04 ±2.00°C, p<0.001) and the pH was also significantly higher (4.60±0.59 vs. 4.17±0.59, p<0.001). In contrast, the elasticity of the areolar was significantly lower (23.52±7.83 vs. 29.02±8.44%, p<0.003). Our findings show, for the first time, that the areolar region has a higher temperature than the surrounding breast skin, together with higher pH values and lower elasticity. We believe that the higher temperature of the areolar region may act as a thermal signal to guide the infant directly to the nipple and to the natural progression of the birth to breastfeeding continuum.

Factors associated to breastfeeding in the first hour of life: systematic review

OBJECTIVE

To identify independent risk factors for non-breastfeeding within the first hour of life.

METHODS

A systematic review of Medline, LILACS, Scopus, and Web of Science electronic databases, till August 30, 2013, was performed without restrictions on language or date of publishing. Studies that used regression models and provided adjusted measures of association were included. Studies in which the regression model was not specified or those based on specific populations regarding age or the presence of morbidities were excluded.

RESULTS

The search resulted in 155 articles, from which 18 met the inclusion criteria. These were conducted in Asia (9), Africa (5), and South America (4), between 1999 and 2013. The prevalence of breastfeeding within the first hour of life ranged from 11.4%, in a province of Saudi Arabia, to 83.3% in Sri Lanka. Cesarean delivery was the most consistent risk factor for non-breastfeeding within the first hour of life. "Low family income", "maternal age less than 25 years", "low maternal education", "no prenatal visit", "home delivery", "no prenatal guidance on breastfeeding" and "preterm birth" were reported as risk factors in at least two studies.

CONCLUSIONS

Besides the hospital routines, indicators for low socioeconomic status and poor access to health services were also identified as independent risk factors for non-breastfeeding within the first hour of life. Policies to promote breastfeeding, appropriate to each context, should aim to reduce inequalities in health.

Effective suckling in relation to naked maternal-infant body contact in the first hour of life: an observation study

BACKGROUND

Best practice guidelines to promote breastfeeding suggest that (i) mothers hold their babies in naked body contact immediately after birth, (ii) babies remain undisturbed for at least one hour and (iii) breastfeeding assistance be offered during this period. Few studies have closely observed the implementation of these guidelines in practice. We sought to evaluate these practices on suckling achievement within the first hour after birth.

METHODS

Observations of seventy-eight mother-baby dyads recorded newborn feeding behaviours, the help received by mothers and birthing room practices each minute, for sixty minutes.

RESULTS

Duration of naked body contact between mothers and their newborn babies varied widely from 1 to 60 minutes, as did commencement of suckling (range = 10 to 60 minutes). Naked maternal-infant body contact immediately after birth, uninterrupted for at least thirty minutes did not predict effective suckling within the first hour of birth. Newborns were four times more likely to sustain deep rhythmical suckling when their chin made contact with their mother's breast as they approached the nipple (OR 3.8; CI 1.03 - 14) and if their mothers had given birth previously (OR 6.7; CI 1.35 - 33). Infants who had any naso-oropharyngeal suctioning administered at birth were six times less likely to suckle effectively (OR .176; CI .04 - .9).

CONCLUSION

Effective suckling within the first hour of life was associated with a collection of practices including infants positioned so their chin can instinctively nudge the underside of their mother's breast as they approach to grasp the nipple and attach to suckle. The best type of assistance provided in the birthing room that enables newborns to sustain an effective latch was paying attention to newborn feeding behaviours and not administering naso-oropharyngeal suction routinely.

Breastfeeding and postpartum depression: state of the art review

OBJECTIVE

To review the literature on the association between breastfeeding and postpartum depression.

SOURCES

A review of literature found on MEDLINE/PubMed database.

SUMMARY OF FINDINGS

The literature consistently shows that breastfeeding provides a wide range of benefits for both the child and the mother. The psychological benefits for the mother are still in need of further research. Some studies point out that pregnancy depression is one of the factors that may contribute to breastfeeding failure. Others studies also suggest an association between breastfeeding and postpartum depression; the direction of this association is still unclear. Breastfeeding can promote hormonal processes that protect mothers against postpartum depression by attenuating cortisol response to stress. It can also reduce the risk of postpartum depression, by helping the regulation of sleep and wake patterns for mother and child, improving mother's self-efficacy and her emotional involvement with the child, reducing the child's temperamental difficulties, and promoting a better interaction between mother and child.

CONCLUSIONS

Studies demonstrate that breastfeeding can protect mothers from postpartum depression, and are starting to clarify which biological and psychological processes may explain this protection. However, there are still equivocal results in the literature that may be explained by the methodological limitations presented by some studies.

A Realistic Evaluation of Two Training Programs on Implementing Skin-to-Skin as a Standard of Care

The authors used realistic evaluation to examine the real-world effectiveness of two 5-day training techniques on sustained optimal skin-to-skin practices that support Step 4 of the revised Baby-Friendly Hospital Initiative (BFHI). The authors found that education alone was insufficient to effect sustainable practice change. Exposure to the 5-day immersion model (Practice, Reflection, Education and training, Combined with Ethnography for Sustainable Success, or PRECESS) alone or combined with education was an effective strategy to change and sustain the standard of care for skin-to-skin practice (p < 0.00001). The intended outcome of sustained practice change toward implementation of skin-to-skin care through immersion or a combined approach shows promise and should be repeated in other localities.

Knowledge, attitude, and practices regarding early start of breastfeeding among pregnant, lactating women and healthcare workers in El-Minia University Hospital

BACKGROUND

Breastfeeding within the first hour of life is a potential mechanism for health promotion and is considered to be an indicator of excellence of breastfeeding. This study was conducted to evaluate the knowledge, attitude, and practice regarding early breastfeeding initiation within the first hour of life in both the Pediatrics and Gynecology and Obstetrics Departments of Minia University Hospital, Minia, Egypt.

SUBJECTS AND METHODS

A study was conducted on four groups of participants from both the Pediatrics and Gynecology and Obstetrics Departments of Minia University Hospital, each of them consisting of 30 individuals, using a questionnaire to assess the knowledge, attitude, and practice regarding early breastfeeding initiation for each group.

RESULTS

Sixty percent of women delivered by spontaneous vaginal delivery and 16.7% of those delivered by cesarean section initiated breastfeeding within 30 minutes to 1 hour after birth. Forty percent of lactating women delivered by spontaneous vaginal delivery, 83.3% of lactating women delivered by cesarean section, and 36.7% of healthcare workers used prelacteal feed instead of early breastfeeding initiation. The most important factors affecting the breastfeeding initiation were maternal illness followed by immediate skin-to-skin contact.

CONCLUSIONS

Although the majority of women participating in this study exhibited knowledge about early breastfeeding initiation, actual application of this practice was clearly deficient. In order to improve the rates of breastfeeding initiation within the first hour of life we should enhance vaginal delivery and prenatal classes and implement Baby-Friendly Hospital Initiative policies in both the Pediatrics and Gynecology and Obstetrics Departments of Minia University Hospital.

Impact and feasibility of breast crawl in a tertiary care hospital

OBJECTIVE

To determine the impact of breast crawl on breast feeding and its feasibility and acceptability in a busy labor room.

STUDY DESIGN

A prospective, single blinded, randomized controlled clinical trial. Impact of breast crawl was studied in one group and the outcome was compared with the other group where breast crawl was not performed. Feasibility and acceptability was determined by analysis of questionnaire given to obstetricians and nurses. Descriptive statistics and χ(2)-analysis was applied to evaluate the questionnaire and to compare the outcome in the two groups.

RESULT

Breast crawl had a significant positive impact on the onset of lactation (P=0.0005) as well as extent of neonatal weight loss on day 3 (0.032).

CONCLUSION

Our study adds to the body of evidence that breast crawl results in positive short-term breast feeding outcome but acceptability of breast crawl as a routine in a busy labor room remains a major issue.

Fetal exposure to synthetic oxytocin and the relationship with prefeeding cues within one hour postbirth

BACKGROUND

Prefeeding cues are oral-motor neurobehaviors that communicate feeding readiness, and the ability to self-comfort and regulate behavioral state. Intrapartum and newborn procedures have been associated with altered frequency and emergence of prefeeding cues soon after birth. Intrapartum synthetic oxytocin is commonly used for labor induction/augmentation in the US, yet there is little research on potential effects on infant neurobehavioral cues.

AIMS

To explore whether fetal exposure to synthetic oxytocin was associated with the infant's level of prefeeding organization shortly after birth.

STUDY DESIGN

Cohort.

SUBJECTS

A convenience sample of 47 healthy full-term infants (36 exposed and 11 unexposed to intrapartum synthetic oxytocin) was studied.

EXCLUSION CRITERIA

Fetal distress, vacuum/forceps, cesarean, and low Apgar.

OUTCOME MEASURES

Videotapes of infants (45-50min postbirth) were coded for frequency of eight prefeeding cues, and analyzed by level of prefeeding organization.

RESULTS

In general, fewer prefeeding cues were observed in infants exposed versus unexposed to synOT and differences were significant for brief and sustained hand to mouth cues [incidence rate ratio (95% CI)=0.6 (0.4, 0.9) and 0.5 (0.2, 0.9), respectively]. Forty-four percent of exposed infants demonstrated a low level of prefeeding organization, compared to 0% from the unexposed group. In contrast, 25% of exposed versus 64% of unexposed infants demonstrated high prefeeding organization. After adjusting for covariates, exposed infants were at 11.5 times (95% CI=1.8-73.3) the odds of demonstrating low/medium versus high levels of prefeeding organization compared to unexposed infants.

CONCLUSIONS

Newborn neurobehavioral cues may be sensitive to intrapartum synthetic oxytocin.

Influence of Skin-to-Skin Contact and Rooming-In on Early Mother–Infant Interaction

The objective of this research was to study influence of birth routines on mother–infant interaction at Day 4. The present research is part of a longitudinal study where mother–infant pairs were randomized by infant location and apparel. We intended to assess mother–infant interaction from videos filmed at Day 4. A protocol for the assessment/coding of the affective quality of maternal behaviors indicative of early mother–infant interaction was developed and interculturally validated. Results were compared with birth randomization, as to explain impact of birth practices. Findings indicate that separation and swaddling at birth interfered with mother–infant interaction during a breastfeeding session at Day 4; these mothers significantly demonstrated more roughness in their behaviors with their infants at Day 4. Results also show evidences of a sensitive period for separation after birth. Implications are to encourage immediate and uninterrupted skin-to-skin contact at birth, and rooming-in during postpartum, as recommended in World Health Organization/UNICEF Ten Steps for Successful Breastfeeding.

Early skin-to-skin contact for mothers and their healthy newborn infants

BACKGROUND

Mother-infant separation postbirth is common in Western culture. Early skin-to-skin contact (SSC) begins ideally at birth and involves placing the naked baby, head covered with a dry cap and a warm blanket across the back, prone on the mother's bare chest. According to mammalian neuroscience, the intimate contact inherent in this place (habitat) evokes neurobehaviors ensuring fulfillment of basic biological needs. This time may represent a psychophysiologically 'sensitive period' for programming future physiology and behavior.

OBJECTIVES

To assess the effects of early SSC on breastfeeding, physiological adaptation, and behavior in healthy mother-newborn dyads.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2011), made personal contact with trialists, and consulted the bibliography on kangaroo mother care (KMC) maintained by Dr. Susan Ludington.

SELECTION CRITERIA

Randomized controlled trials comparing early SSC with usual hospital care.

DATA COLLECTION AND ANALYSIS

We independently assessed trial quality and extracted data. Study authors were contacted for additional information.

MAIN RESULTS

Thirty-four randomized controlled trials were included involving 2177 participants (mother-infant dyads). Data from more than two trials were available for only eight outcome measures. For primary outcomes, we found a statistically significant positive effect of early SSC on breastfeeding at one to four months postbirth (13 trials; 702 participants) (risk ratio (RR) 1.27, 95% confidence interval (CI) 1.06 to 1.53, and SSC increased breastfeeding duration (seven trials; 324 participants) (mean difference (MD) 42.55 days, 95% CI -1.69 to 86.79) but the results did not quite reach statistical significance (P = 0.06). Late preterm infants had better cardio-respiratory stability with early SSC (one trial; 31 participants) (MD 2.88, 95% CI 0.53 to 5.23). Blood glucose 75 to 90 minutes following the birth was significantly higher in SSC infants (two trials, 94 infants) (MD 10.56 mg/dL, 95% CI 8.40 to 12.72).The overall methodological quality of trials was mixed, and there was high heterogeneity for some outcomes.

AUTHORS' CONCLUSIONS

Limitations included methodological quality, variations in intervention implementation, and outcomes. The intervention appears to benefit breastfeeding outcomes, and cardio-respiratory stability and decrease infant crying, and has no apparent short- or long-term negative effects. Further investigation is recommended. To facilitate meta-analysis, future research should be done using outcome measures consistent with those in the studies included here. Published reports should clearly indicate if the intervention was SSC with time of initiation and duration and include means, standard deviations and exact probability values.

Influence of common birth interventions on maternal blood pressure patterns during breastfeeding 2 days after birth

OBJECTIVE

This study investigated possible influences of medical interventions during labor on maternal blood pressure during a breastfeed 2 days postpartum.

SUBJECTS AND METHODS

Sixty-six primiparae with normal deliveries were consecutively recruited. Blood pressure was measured at -5, 10, 30, and 60 minutes during a morning breastfeed 2 days postpartum. Five treatment groups were formed based on the medical interventions received during labor: Non-medicated mothers (Control group, n=21); mothers receiving epidural analgesia (EDA) with oxytocin (OT) stimulation (EDA(OT) group, n=14); mothers receiving EDA without OT stimulation (EDA(non-OT) group, n=7); mothers receiving OT stimulation only (OT intravenously [iv] group, n=9); and mothers receiving 10 IU of OT intramuscularly (im) only (OT im group, n=15).

RESULTS

Baseline diastolic, but not systolic, blood pressure differed between the groups as displayed by significantly lower diastolic blood pressure in the EDA(non-OT) group compared with the Control group, the OT iv group, and the EDA(OT) group (p=0.045, p=0.041, and p=0.024, respectively). Both systolic and diastolic blood pressure fell significantly during the breastfeeding session in the Control group (p=0.001 and p=0.004, respectively), the OT im group (p=0.006 and p=0.001, respectively), and the EDA(OT) group (p=0.028 and p=0.002, respectively), and the fall in diastolic blood pressure tended to be significant in the OT iv group (p=0.050). The duration of skin-to-skin contact before breastfeeding correlated positively with the decrease in systolic blood pressure in the OT im group (R(s)=0.540, p=0.046).

CONCLUSION

Administration of EDA during labor lowers baseline diastolic blood pressure and abolishes the fall in blood pressure in response to a breastfeed 2 days after birth.

An overlooked aspect of the human breast: areolar glands in relation with breastfeeding pattern, neonatal weight gain, and the dynamics of lactation

The early nursing-sucking relationship is not to be taken for granted in humans. A number of factors can either facilitate or mitigate its optimal establishment on the mother's or newborn's sides. Among these factors, a morphological feature of human mothers' breasts--the areolar glands (AG)--has been identified as potentially important. Three day-old infants display attraction during the presentation of the native secretions of the AG, suggesting that they could influence the newborn's behaviour during breastfeeding. The present study assessed this topic in a sample of 121 Caucasian mother-infant dyads. The areolae of these women were screened during the first 3 postnatal days in parallel with the infant's sucking performance, body weight fluctuations and time to lactation onset. On average, 97% of the women bore AG, 80.2% having 1-20 units per areola and 33% showing AG excreting a visible fluid. The endowment in AG appeared positively linked with neonatal growth after birth and with the speed of lactation onset: infants of primiparous women with lower AG numbers had a lower weight gain than those of mothers with higher AG numbers. Further, it took longer to primiparae with lower AG counts to set on lactation. This study confirms and extends the fact that AG, in interaction with maternal experience, might influence the initiation of the breastfeeding relationship.

[The mother-infant encounter at birth must be protected]

The medical decision to separate a newborn baby from his or her mother is frequent. This medical practice must be evaluated. The scientific literature regarding humans and other mammals was reviewed in order to describe the physiology of the interactions between mother and offspring and the consequences of disrupting their interactions around birth. Mother-infant bonding is common to all mammals. Attachment is the result of three mechanisms: behavioral programing, secretion of neuroendocrine substrates, and activation of sensory cues. Breastfeeding is a fourth component that plays a crucial role. Experimental research provides evidence that early-life maternal separation can alter biological responses to stress, disturb learning behaviors, and impair social skills. Recent advances in epigenetic research may partly explain how neonatal maternal deprivation at birth can lead to biological and behavioral disorders in adulthood. Therefore, the decision to separate a newborn infant from his or her mother is not harmless and must be carefully considered. In order to better take into account these data, the organization of perinatal care in France should be revised.

The Newborn Individualized Developmental Care and Assessment Program (NIDCAP) with Kangaroo Mother Care (KMC): Comprehensive Care for Preterm Infants

State-of-the-art Newborn Intensive Care Units (NICUs), instrumental in the survival of high-risk and ever-earlier-born preterm infants, often have costly human repercussions. The developmental sequelae of newborn intensive care are largely misunderstood. Developed countries eager to export their technologies must also transfer the knowledge-base that encompasses all high-risk and preterm infants' personhood as well as the neuro-essential importance of their parents. Without such understanding, the best medical care, while assuring survival jeopardizes infants' long-term potential and deprives parents of their critical role. Exchanging the womb for the NICU environment at a time of rapid brain growth compromises preterm infants' early development, which results in long-term physical and mental health problems and developmental disabilities. The Newborn Individualized Developmental Care and Assessment Program (NIDCAP) aims to prevent the iatrogenic sequelae of intensive care and to maintain the intimate connection between parent and infant, one expression of which is Kangaroo Mother Care. NIDCAP embeds the infant in the natural parent niche, avoids over-stimulation, stress, pain, and isolation while it supports self-regulation, competence, and goal orientation. Research demonstrates that NIDCAP improves brain development, functional competence, health, and life quality. It is cost effective, humane, and ethical, and promises to become the standard for all NICU care.

Randomized controlled trial of early skin-to-skin contact: effects on the mother and the newborn

OBJECTIVE

To estimate the influence of skin-to-skin care on the thermal regulation of the infant and the rate of breastfeeding at different points of time. We also aim to establish whether skin-to-skin contact reduces maternal pain during episiotomy repair and decreases the time to expel the placenta.

METHODS

A randomized control study was performed with 137 patients in each branch of the study. Differences between the study groups were analysed with the unpaired t-test, Fisher test or chi-square test as appropriate.

RESULTS

Greater thermal stability in the skin-to-skin care group was found where an average temperature rise of 0.07°C was observed. Mothers in the skin-to-skin care group exclusively breastfed more frequently at discharge. Mean time to expel the placenta was lesser in the skin-to-skin care group.

CONCLUSION

This study shows that skin-to-skin care implies better thermal regulation and a better proportion of exclusive breastfeeding at hospital discharge.

Extended cognition and the space of social interaction

The extended mind thesis (EM) asserts that some cognitive processes are (partially) composed of actions consisting of the manipulation and exploitation of environmental structures. Might some processes at the root of social cognition have a similarly extended structure? In this paper, I argue that social cognition is fundamentally an interactive form of space management--the negotiation and management of "we-space"--and that some of the expressive actions involved in the negotiation and management of we-space (gesture, touch, facial and whole-body expressions) drive basic processes of interpersonal understanding and thus do genuine social-cognitive work. Social interaction is a kind of extended social cognition, driven and at least partially constituted by environmental (non-neural) scaffolding. Challenging the Theory of Mind paradigm, I draw upon research from gesture studies, developmental psychology, and work on Moebius Syndrome to support this thesis.

Onset of vocal interaction between parents and newborns in skin-to-skin contact immediately after elective cesarean section

BACKGROUND

Cesarean section is associated with delayed mother-infant interaction because neither the mother nor the father routinely maintains skin-to-skin contact with the infant after birth. The aim of the study was to explore and compare parent-newborn vocal interaction when the infant is placed in skin-to-skin contact either with the mother or the father immediately after a planned cesarean section.

METHODS

A total of 37 healthy infants born to primiparas were randomized to 30 minutes of skin-to-skin contact either with fathers or mothers after an initial 5 minutes of skin-to-skin contact with the mothers after birth. The newborns' and parents' vocal interaction were recorded on a videotape and audiotape. The following variables were explored: newborns' and parents' soliciting, newborns' crying and whining, and parental speech directed to the other parent and to the newborn.

RESULTS

Newborns' soliciting increased over time (p=0.032). Both fathers and mothers in skin-to-skin contact communicated more vocally with the newborn than did fathers (p=0.003) and mothers (p=0.009) without skin-to-skin contact. Fathers in skin-to-skin contact also communicated more with the mother (p=0.046) and performed more soliciting responses than the control fathers (p=0.010). Infants in skin-to-skin contact with their fathers cried significantly less than those in skin-to-skin contact with their mothers (p=0.002) and shifted to a relaxed state earlier than in skin-to-skin contact with mothers (p=0.029).

CONCLUSIONS

Skin-to-skin contact between infants and parents immediately after planned cesarean section promotes vocal interaction. When placed in skin-to-skin contact and exposed to the parents' speech, the infants initiated communication with soliciting calls with the parents within approximately 15 minutes after birth. These findings give reason to encourage parents to keep the newborn in skin-to-skin contact after cesarean section, to support the early onset of the first vocal communication.

Are maternal depression or symptom severity associated with breastfeeding intention or outcomes?

OBJECTIVE

Breastfeeding confers many health benefits to mothers and infants, while depression negatively affects mothers and infants. The aims of this study were to determine relationships between (1) major depressive disorder (MDD) and depressive symptom severity during pregnancy and breastfeeding intention; (2) MDD and depressive symptom severity during pregnancy and breastfeeding initiation and status at 2 and 12 weeks; and (3) serotonin reuptake inhibitor (SRI) use and breastfeeding intention, initiation, and status at 2 and 12 weeks.

METHOD

Women were followed prospectively from pregnancy through 12 weeks postpartum for infant feeding intention (breast, breast and formula, formula, and uncertain), feeding practices and MDD (Structured Clinical Interview for DSM-IV Disorders), and depressive symptom severity (Hamilton Depression Rating Scale). Bivariate analyses and multivariable regression modeling were conducted. The study was conducted from July 2004 to September 2007.

RESULTS

Study participants (intention n = 168, initiation n = 151, 2 weeks n = 137, 12 weeks n=103) were well educated (63% college degrees), older (49% ≥ or = 31 years), and predominantly white (77%). At enrollment, 23% had MDD, 21% had significant depressive symptoms, and 16% were taking an SRI. Neither MDD nor depressive symptom severity in pregnancy was related to breastfeeding intention, initiation or duration at 2 and 12 weeks. Intention to exclusively breastfeed was the most significant predictor of breastfeeding initiation and duration. SRI use in pregnancy was negatively associated with breastfeeding intention. SRI use at 2 weeks was negatively associated with 12-week breastfeeding status.

CONCLUSION

Pregnancy is the optimal time to intervene to increase breastfeeding rates. Future research should identify strategies to overcome breastfeeding barriers posed by SRI use.

Early contact versus separation: effects on mother-infant interaction one year later

BACKGROUND

A tradition of separation of the mother and baby after birth still persists in many parts of the world, including some parts of Russia, and often is combined with swaddling of the baby. The aim of this study was to evaluate and compare possible long-term effects on mother-infant interaction of practices used in the delivery and maternity wards, including practices relating to mother-infant closeness versus separation.

METHODS

A total of 176 mother-infant pairs were randomized into four experimental groups: Group I infants were placed skin-to-skin with their mothers after birth, and had rooming-in while in the maternity ward. Group II infants were dressed and placed in their mothers' arms after birth, and roomed-in with their mothers in the maternity ward. Group III infants were kept in the nursery both after birth and while their mothers were in the maternity ward. Group IV infants were kept in the nursery after birth, but roomed-in with their mothers in the maternity ward. Equal numbers of infants were either swaddled or dressed in baby clothes. Episodes of early suckling in the delivery ward were noted. The mother-infant interaction was videotaped according to the Parent-Child Early Relational Assessment (PCERA) 1 year after birth.

RESULTS

The practice of skin-to-skin contact, early suckling, or both during the first 2 hours after birth when compared with separation between the mothers and their infants positively affected the PCERA variables maternal sensitivity, infant's self-regulation, and dyadic mutuality and reciprocity at 1 year after birth. The negative effect of a 2-hour separation after birth was not compensated for by the practice of rooming-in. These findings support the presence of a period after birth (the early "sensitive period") during which close contact between mother and infant may induce long-term positive effect on mother-infant interaction. In addition, swaddling of the infant was found to decrease the mother's responsiveness to the infant, her ability for positive affective involvement with the infant, and the mutuality and reciprocity in the dyad.

CONCLUSIONS

Skin-to-skin contact, for 25 to 120 minutes after birth, early suckling, or both positively influenced mother-infant interaction 1 year later when compared with routines involving separation of mother and infant.

Treatment of opioid-dependent pregnant women: clinical and research issues

This article addresses common questions that clinicians face when treating pregnant women with opioid dependence. Guidance, based on both research evidence and the collective clinical experience of the authors, which include investigators in the Maternal Opioid Treatment: Human Experimental Research (MOTHER) project, is provided to aid clinical decision making. The MOTHER project is a double-blind, double-dummy, flexible-dosing, parallel-group clinical trial examining the comparative safety and efficacy of methadone and buprenorphine for the treatment of opioid dependence in pregnant women and their neonates. The article begins with a discussion of appropriate assessment during pregnancy and then addresses clinical management stages including maintenance medication selection, induction, and stabilization; opioid agonist medication management before, during, and after delivery; pain management; breast-feeding; and transfer to aftercare. Lastly, other important clinical issues including managing co-occurring psychiatric disorders and medication interactions are discussed.

Short- and long-term decrease of blood pressure in women during breastfeeding

BACKGROUND AND AIMS

The benefits of breastfeeding for infants are well known. Recently data have started to emerge showing that breastfeeding may also induce positive effects in the mother. This study aimed to investigate the pattern of maternal blood pressure before, during, and after a breastfeed 2 days postpartum. Additionally, blood pressure during the following 25-week breastfeeding period was investigated.

METHODS

Sixty-six primiparae with normal deliveries were consecutively recruited. Blood pressure was measured at -5, 10, 30, and 60 minutes in connection with a morning breastfeed. Thirty-three women continued to measure blood pressure before and after breastfeeding for 25 weeks.

RESULTS

Blood pressure fell significantly in response to breastfeeding 2 days after birth. The fall in systolic and diastolic blood pressure amounted to 8.8 (SD = 11.00) and 7.7 (SD = 9.3) mm Hg, respectively. During the 25-week follow-up period a significant fall of basal blood pressure (systolic, df = 3, F = 7.843, p < 0.001; diastolic, df = 3, F = 5.453, p = 0.002) was observed. The total fall in systolic and diastolic blood pressure amounted to a mean of 15 (SD = 10.4) mm Hg and 10 (SD = 9.7) mm Hg, respectively. In addition, blood pressure fell significantly in response to individual breastfeeding sessions during the entire observation period.

CONCLUSIONS

In conclusion, both systolic and diastolic blood pressures fall during a breastfeeding session, and pre-breastfeeding blood pressure decreases during at least the first 6 months of a breastfeeding period in a homelike environment. This study lends further support to the health-promoting effects of breastfeeding.

Fatores associados ao início da amamentação em uma cidade do sul do Brasil

OBJETIVOS: identificar as características - maternas, dos bebês e das maternidades - associadas com o início da amamentação na primeira hora após o parto. MÉTODOS: estudo transversal aninhado em coorte que acompanhou bebês de mães residentes em Pelotas, Rio Grande do Sul. As mães responderam a questionário padronizado, com dados referentes a fatores demográficos e socioeconômicos, pré-natal, características maternas do bebê, da maternidade, condições de nascimento e início da amamentação. As entrevistas foram realizadas através de visitas diárias às maternidades, respeitando um período mínimo de quatro horas após o parto. Foram realizadas análise univariada, bivariada e regressão logística. RESULTADOS: foram entrevistadas 2741 mães, sendo que 35,5% amamentaram na primeira hora pós-parto. As que mais precocemente iniciaram a amamentação foram as de menor idade, menor escolaridade e menor renda. Mães cujo parto foi cesárea tiveram um risco cerca de duas vezes maior de não amamentar na primeira hora de vida. CONCLUSÕES: é importante a indicação adequada do tipo de parto, pois a cesárea aumenta o tempo de separação mãe-bebê. É relevante estimular a expansão da Iniciativa Hospital Amigo da Criança, pela capacidade de promover e proteger o aleitamento.
