Psychological distress and early lactation performance in mothers of late preterm infants

Pressure to provide milk among mothers of very low birth weight infants: an explorative study

BACKGROUND

Pump-dependent mothers of very low birth weight (VLBW, < 1500g) infants experience specific challenges achieving sufficient milk supply in the neonatal intensive care unit (NICU) and are therefore less frequently able to achieve (exclusive) breast milk feeding. Stress due to the limitations on participating in the infant's care may contribute to this problem. Some explorative studies suggest that pressure to provide milk may be an additional stressor in mothers. However, the type of pressure to provide milk perceived by mothers of VLBW infants has rarely been examined.

METHODS

A retrospective and anonymous questionnaire was conducted with mothers of VLBW infants aged 6 to 24 months at the time of data collection. Quantitative data and written comments were used to examine the mothers' perceptions. Descriptive and bivariate tests (Spearman´s rho, Pearson's chi2) were performed to show correlations between pressure to provide breast milk, parental stress (PSS:NICU: role alteration subscale), milk volume, and maternal factors. Pressure to provide milk was measured through two self-developed single items to differentiate between internal and external pressures.

RESULTS

Data of n = 533 mothers of VLBW infants was analysed. More than 70% of the mothers agreed that they pressured themselves to provide milk for their infant. In contrast, 34% of the mothers agreed that they felt pressure from outside to provide milk. Higher milk volume 14 days post-partum was significantly correlated with higher internal (Spearman´s rho = 0.2017, p = 0.000) and higher external pressure to provide milk (Spearman´s rho = 0.2991; p = 0.000). Higher PSS:NICU parental role alteration scores were significantly correlated with more internal (Spearman´s rho = -0.2865, p = 0.000) and more external pressure to provide milk (Spearman´s rho = -0.1478; p = 0.002). Milk volume 14 days post-partum and the PSS:NICU were not significantly correlated (Spearman´s rho = -0.0190; p = 0.701). Qualitative analyses highlighted these results and enhanced the bidirectional relationships between maternal pressure to provide milk and milk volume.

CONCLUSIONS

Especially internal pressure to provide milk is perceived by many mothers, being mutually dependent on milk supply and parental stress. Pressure to provide milk may be an important factor to decrease maternal stress in the NICU and, therefore, lead to more positive pumping and breastfeeding experiences. More research and validated instruments are needed to adequately measure pressure to provide milk with its different psychological, social, and environmental dimensions.

Feeding Difficulties in Late Preterm Infants and Their Impact on Maternal Mental Health and the Mother-Infant Relationship: A Literature Review

Late preterm infants constitute the largest subset of premature infants and are more likely to experience feeding issues leading to delayed oral feeding independence and low breastfeeding rates. Considering the increased parental concern about their infants' nutrition and growth, we performed a literature review to provide an update on the feeding challenges faced by late preterm infants and the impact of these issues on maternal mental health and the mother-infant relationship. Based on our findings, late preterm infants have a high prevalence of feeding difficulties which need to be addressed by targeted support interventions to promote breastfeeding success and the establishment of a harmonious dyadic interaction between the mother and her infant, all of which contribute to the prevention of altered feeding behavior later in life. There is still a need for additional research to develop a standardized and shared strategy that can be proven to be effective. Should this be accomplished, it will be possible to offer appropriate support for mothers, encourage the oral skills and maturation of late preterm infants, and improve the relationship quality within the dyad.

A Breastfeeding Relaxation Intervention Promotes Growth in Late Preterm and Early Term Infants: Results from a Randomized Controlled Trial

Breastfeeding involves signaling between mother and offspring through biological (breast milk) and behavioral pathways. This study tested this by examining the effects of a relaxation intervention in an understudied infant population. Breastfeeding mothers of late preterm (34^0/7-36^6/7 weeks) and early term (37^0/7-38^6/7 weeks) infants were randomized to the relaxation group (RG, n = 35), where they were asked to listen to a meditation recording while breastfeeding from 3 weeks post-delivery, or the control group (CG, n = 37) where no intervention was given. Primary outcomes-maternal stress and infant weight-were assessed at 2-3 (baseline) and 6-8 weeks post-delivery. Secondary outcomes included infant length, infant behavior, maternal verbal memory, salivary cortisol, and breast milk composition. Infants in the RG had significantly higher change in weight-for-age Z-score compared to those in CG (effect size: 0.4; 95% CI: 0.09, 0.71; p = 0.01), and shorter crying duration [RG: 5.0 min, 0.0-120.0 vs. CG: 30.0 min, 0.0-142.0; p = 0.03]. RG mothers had greater reduction in cortisol (effect size: -0.08 ug/dL, 95% CI -0.15, -0.01; p = 0.03) and better maternal verbal learning score (effect size: 1.1 words, 95% CI 0.04, 2.1; p = 0.04) than CG mothers, but did not differ in stress scores. A simple relaxation intervention during breastfeeding could be beneficial in promoting growth of late preterm and early term infants. Further investigation of other potential biological and behavioral mediators is warranted.

Preterm birth and postpartum depression within 6 months after childbirth in a Brazilian cohort

Preterm birth (PTB) and postpartum depression (PPD) are important public health issues, and although literature mainly supports the association between them, some reviews have highlighted methodological limitations in the studies in this field, restricting the interpretation of such finding. This study aimed at assessing the association between PTB and PPD, by comparing groups of preterm and full-term mothers in two Brazilian cities with contrasting sociodemographic indicators. This prospective convenience cohort study assessed 1421 women during pregnancy, at childbirth, and in the postpartum period. The Edinburgh Postnatal Depression Scale (EPDS) was administrated to assess PPD within 6 months after delivery and women were considered probably depressed if scores were EDPS ≥ 12. PTB was defined as the delivery before 37 completed weeks of pregnancy. A multivariate Poisson regression was used to estimate relative risk for PPD in mothers of preterm infants, and the final analysis models were adjusted for psychosocial variables, selected according to the directed acyclic graph (DAG) approach. Frequencies of PPD were not significantly different in mothers of preterm and full-term infants, in neither city. In the final adjusted model, PTB was not associated with PPD. The association between PTB and PPD was not confirmed in two large samples from two Brazilian cities with contrasting socioeconomic profile. However, maternal health during pregnancy plays an important role in predicting PPD. Prenatal care should promote maternal mental health as an effort towards decreasing unfavored outcomes for mothers, infants, and families.

Nutritional Management of Moderate- and Late-Preterm Infants Commenced on Intravenous Fluids Pending Mother's Own Milk: Cohort Analysis From the DIAMOND Trial

BACKGROUND

Exclusive breastmilk is the desired enteral nutrition for babies born moderate- and late-preterm between 32⁺⁰ and 36⁺⁶ weeks' gestation; however, this goal is often difficult to achieve.

METHODS

A prospective cohort of babies 32⁺⁰ -35⁺⁶ weeks' gestation enrolled in the DIAMOND trial were randomized to a condition specifying that babies should receive mother's own milk (MOM) as the only enteral feed. Factors associated with the successful transition to MOM, defined as MOM being the sole enteral feeding at the time of the first cessation of intravenous (IV) fluids, were investigated by logistic regression. Time to commencement of a milk other than MOM was analyzed by Kaplan-Meier survival curves.

RESULTS

A total of 151 eligible babies (60% boys) were included, 93 (63%) of whom successfully transitioned from IV fluids onto MOM only. Alternative sources of milk, mostly formula, were used to transition from IV fluids onto enteral feeds more often in multiples and Māori, and was commenced earlier in Māori than other ethnicities (p = 0.007) and in late-preterm compared with moderate-preterm babies (p=0.01). Receiving exclusively breastmilk at discharge was more likely for babies who successfully transitioned from IV fluids onto MOM only [OR (95% confidence intervals) 4.9 (2.3-10.6)] and who received only MOM in the first week after birth [4.8 (2.2-10.4)], both p < 0.0001. Receiving breastmilk exclusively at discharge was less likely for Māori than Caucasian babies [0.2 (0.1-0.6), p < 0.0006]. There was no difference in the use of alternative sources of milk in babies who received parenteral nutrition or dextrose or between small-for-gestational-age and appropriate-for-gestational-age babies.

CONCLUSIONS

Despite an intention to provide only MOM, significant numbers of moderate- and late-preterm babies received formula to transition from IV fluids, and this differed by ethnicity. The drivers underlying these decisions require further investigation. These data highlight an urgent need for quality initiatives to support and encourage mothers of moderate- and late-preterm babies in their lactation.

T3 is linked to stress-associated reduction of prolactin in lactating women

The relationship between stress responses and lactation is bidirectional. Breastfeeding confers many benefits to maternal health, including attenuated hypothalamic-pituitary-adrenal axis responsiveness to stress. However, increased stress burden can impair lactation. The mechanisms that underlie these relationships are poorly understood. The present study aimed to compare breastfeeding habits, as well as subjective and objective measures of stress, in employed and non-employed lactating women and assess the relationships between these measures and prolactin (PRL), thyroid hormones (thyroid-stimulating hormone, triiodothyronine [T3] and thyroxine), vasopressin and cortisol levels. A dexamethasone suppression test was also administered to determine the sensitivity of the hypothalamic-pituitary-adrenal axis to negative-feedback. We report that lactating employed women had lower breastfeeding rates and lower PRL than lactating non-employed women. They also had a significantly higher stress burden, indicated by elevations in blood pressure and evening cortisol, relative to lactating non-employed women. In regression analyses that controlled for feeding modality and breastfeeding duration, we found these factors differentially affected PRL in the two groups and there were significant differences in PRL across groups that were not accounted for by these factors. A mediation regression analysis suggested that group differences in PRL were best explained by differences in T3 and income levels, rather than breastfeeding duration or other variables. Our data fit a speculative model in which elevated maternal stress increases cortisol, which suppresses T3, leading to decreased PRL. The decreases in PRL are associated with higher rates of bottlefeeding, which may further contribute to decreased PRL.

Amplitude Integrated Electroencephalogram Integration to Monitor the Relationship Between Development and Changes of the Nervous System in Late Preform Infants

This article uses amplitude integration of electroencephalogram integration to detect the development of the nervous system of late perform infants, and to study its changes, using a stratified randomized controlled trial method. The preform infants in the neonatal department of postnatal birth had the research object. The sample size was calculated, according to the first set of tires into small gestational age groups, and gestational age large. The subjects of each group were randomly divided into small gestational age groups, small gestational age intervention groups, large gestational age groups and large gestational age intervention groups. Two preterm children increased with age growth. The performance of the broadband and narrowband sector decreased voltage need the voltage lower bound ofa growing trend to the voltage difference becomes smaller. Oral exercise intervention is safe and effective for premature infants over 30 weeks old and can be used clinically as a neuroprotective strategy.

Barriers and Facilitators to Breastfeeding in Moderate and Late Preterm Infants: A Systematic Review

Rationale: Most of the preterm infants are born between 32 and 36 weeks of gestation (moderate to late preterm infants [MLPIs]). This comes with significant short- and long-term risks. Breastfeeding reduces many of these risks, but breastfeeding rates in MLPIs are lower than those in full-term infants. We performed a systematic review of studies identifying factors associated with successful breastfeeding in MLPIs and interventions to improve breastfeeding. Methods: Systematic search performed using PubMed April 24, 2020. In total, 11 articles describing barriers to breastfeeding in MLPIs and 6 articles about interventions to improve breastfeeding were included. Interventions were categorized according to different outcomes: breastfeeding initiation, continuation for 5 days to 6 weeks, and continuation ≥3 months. Because of heterogeneity in study characteristics, no meta-analysis was performed. Results: Breastfeeding rates were lower in those with lower socioeconomic status and single-parent households. Providing parents with more information and direct health care support significantly improved breastfeeding initiation. Cup feeding instead of bottle feeding had inconsistent effects on breastfeeding initiation and continuation. Continuous skin-to-skin contact did not affect breastfeeding initiation or continuation. Discussion: Risk groups for lower breastfeeding rates of MLPIs include mothers with lower socioeconomic status and single mothers. Interventions that may improve breastfeeding include cup feeding and providing parents with more information and health care support. Key limitations of included studies are lack of adequate adjustment for confounders and lack of blinding. However, this is the first systematic review identifying both risk groups and interventions to improve breastfeeding in MLPIs.

A shorter breastfeeding duration in late preterm infants than term infants during the first year

AIM

Little attention has been paid to breastfeeding late preterm (LPT) infants. This study compared breastfeeding, worries, depression and stress in mothers of LPT and term-born infants throughout the first year. We also described factors associated with shorter breastfeeding duration of LPT infants.

METHODS

This longitudinal cohort study of the mothers of singleton infants-129 born LPT and 277 born at term-was conducted at Landspitali-The National University Hospital of Iceland, which has the country's only neonatal intensive care unit. The mothers answered questionnaires when their infants were 1, 4, 8 and 12 months of age.

RESULTS

Mothers breastfed LPT infants for a significantly shorter time than term infants: a median of 7 months (95% confidence interval 5.53-8.48) vs 9 months (95% confidence interval 8.39-9.61) (P < .05). Starting solids at up to 4 months was the strongest risk factor for LPT breastfeeding cessation during the first year, after adjusting for confounders (P < .001). Their mothers reported more worries about their infants' health and behaviour during the first year and were more likely to experience depression at 4 months.

CONCLUSION

Mothers with LPT infants are vulnerable and need greater practical breastfeeding and emotional support in hospital and at home.

Mother And late Preterm Lactation Study (MAPLeS): a randomised controlled trial testing the use of a breastfeeding meditation by mothers of late preterm infants on maternal psychological state, breast milk composition and volume, and infant behaviour and growth

Background

Late preterm infants suffer from more complications and are less likely to be breastfed compared to term infants and their mothers experience higher levels of stress than mothers with term infants. The physiological or hormonal responses that influence milk ejection, milk production, and/or maternal behaviour are possible mechanisms by which maternal distress could negatively influence breastfeeding success. Maternal mood might also affect infant behaviour (feeding, sleeping, and crying) through changes in milk volume and composition, and consequently breastfeeding success and infant growth. Previous research, using relaxation therapy in 64 Malaysian first-time mothers breastfeeding their full-term infants, demonstrated that the therapy was effective in reducing maternal stress and improving infant growth. We hypothesise that expected benefits are even greater in a more vulnerable population where additional breastfeeding support is especially needed, such as in mothers of late preterm infants.

Methods/design

This protocol describes our randomised controlled trial that tests whether a breastfeeding meditation audio reduces maternal stress in mothers of late preterm infants in London. Home visits will be conducted at 2–3 and 6–8 weeks post-delivery. Participants will be randomised to a control group or an intervention group, where mothers will be asked to listen to a meditation tape on a daily basis while breastfeeding. The main outcomes of the intervention will be maternal stress markers and infant weight Z-score. Potential mediators will be the secondary outcomes and include breast milk macronutrient and hormone levels (ghrelin, leptin, cortisol, and adiponectin), milk volume assessed by 48-h test-weighing, and maternal engagement with the infant. Infant behaviour, including crying and sleeping, and infant appetite will be evaluated. Data about other mediators such as maternal perception of milk supply and salivary oxytocin will be collected.

Discussion

We hypothesise that the use of the breastfeeding meditation will reduce maternal stress and consequently improve infant growth mediated by changes in milk composition and volume and maternal behaviour. This study will allow us to understand the mother–infant factors that influence breastfeeding in late preterm infants and potentially identify a method that could improve mother, infant, and breastfeeding outcomes.

You Can't Take Your Baby Home Yet: A Longitudinal Study of Psychological Symptoms in Mothers of Infants Hospitalized in the NICU

Evidence suggests that mothers of infants hospitalized in the Neonatal Intensive Care Unit (NICU) experience elevated rates of psychological symptoms. However, previous studies of this population have been mainly cross-sectional and have focused on very preterm infants. Although moderate- to late-preterm infants generally thrive, the possible psychological toll on their mothers has not yet been sufficiently examined. In the current study, we used a longitudinal design to investigate whether mothers of moderate- to late-preterm infants experience elevated rates of psychological symptoms during the infant's hospitalization in the NICU and 6 months later. Results indicated that these mothers did show elevated depression, anxiety, and PTSD symptoms, and that symptom levels were similar in mothers of moderate- versus late-preterm infants. Mothers of moderate- to late-preterm infants hospitalized in the NICU appeared to experience these symptoms steadily over a 6-month period after giving birth. These findings suggest a need for greater support for these mothers while in the NICU.

Preterm birth as a risk factor for postpartum depression: A systematic review and meta-analysis

BACKGROUND

This systematic review aimed to critically analyze the studies that explored preterm birth as risk factor for postpartum depression in the last 10 years.

METHODS

Two independent researchers performed a systematic review of indexed studies in PubMed/Medline, Web of Science and PsycInfo database. The PRISMA for reporting systematic review model was used to conduct data extraction. A meta-analysis was performed including a sub-group of studies.

RESULTS

The final sample consisted of 26 studies and 12 were included in the meta-analysis. Most of the studies supported the association between preterm birth (PTB) and postpartum depression (PPD). However, 8 studies did not find such association and, even among studies with positive findings, results were heterogeneous, given the methodological discrepancies among the studies. The meta-analysis provided evidence of higher risk for PPD among mothers of preterm infants in assessments performed up to 24 weeks after childbirth.

LIMITATIONS

Most of the studies did not consider the role of important confounding variables, such as previous history of depression. Heterogeneity of assessment tools and cut-off scores were also considered a limitation.

CONCLUSIONS

Further prospective population-based studies with an integrative approach of PPD are needed to provide consistent evidence of such association. Important confounding variables and biological measures implicated in PPD should be considered. Our findings highlight the importance of maternal mental health care in this target population, as preterm birth experience seem to affect both babies and mothers. We encourage PPD assessment for mothers of preterm infants, especially in the early postpartum period.

Feeding the Late and Moderately Preterm Infant: A Position Paper of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition Committee on Nutrition

Nutritional guidelines and requirements for late or moderately preterm (LMPT) infants are notably absent, although they represent the largest population of preterm infants. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee on Nutrition (CoN) performed a review of the literature with the aim to provide guidance on how to feed infants born LMPT, and identify gaps in the literature and research priorities.Only limited data from controlled trials are available. Late preterm infants have unique, often unrecognized, vulnerabilities that predispose them to high rates of nutritionally related morbidity and hospital readmissions. They frequently have feeding difficulties that delay hospital discharge, and poorer rates of breastfeeding initiation and duration compared with term infants. This review also identified that moderately preterm infants frequently exhibit postnatal growth restriction.The ESPGHAN CoN strongly endorses breast milk as the preferred method of feeding LMPT infants and also emphasizes that mothers of LMPT infants should receive qualified, extended lactation support, and frequent follow-up. Individualized feeding plans should be promoted. Hospital discharge should be delayed until LMPT infants have a safe discharge plan that takes into account local situation and resources.In the LMPT population, the need for active nutritional support increases with lower gestational ages. There may be a role for enhanced nutritional support including the use of human milk fortifier, enriched formula, parenteral nutrition, and/or additional supplements, depending on factors, such as gestational age, birth weight, and significant comorbidities. Further research is needed to assess the benefits (improved nutrient intakes) versus risks (interruption of breast-feeding) of providing nutrient-enrichment to the LMPT infant.

Mothers' Depression, Anxiety, and Mental Representations After Preterm Birth: A Study During the Infant's Hospitalization in a Neonatal Intensive Care Unit

Aim: This paper aimed to explore psychological functioning and mental representations in mothers of preterm infants during the child's hospitalization in a Neonatal intensive care unit (NICU).

Methods: A sample including 62 mothers of premature infants (gestational age < 37 weeks) was recruited in a NICU. According to the gestational age at the time of delivery, we considered two groups: Group A included mothers whose children were born before 32 weeks of pregnancy; Group B included mothers whose children were born at or after 32 weeks of pregnancy.

Within one week of childbirth, mothers were administered two self-report questionnaires: the Edinburgh Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI). When their infants' medical conditions became stable, the Clinical Interview for Parents of High-Risk Infants (CLIP) was administered to mothers.

Results: The results showed high levels of depression and anxiety in both groups of mothers, with higher state anxiety scores in Group A than Group B. Besides, a series of hierarchical regression analyses were conducted with STAI, EPDS, and gestational age as predictors on the CLIP scores. Results indicated that EPDS scores predicted CLIP scores on parental self-image, support system, and readiness for discharge (p < 0.001); moreover, the interaction among depression, anxiety, and gestational age predicted the CLIP dimension of feeling of mutual recognition (p < 0.005).

Conclusions: These findings suggested that a premature birth and the child's hospitalization might exert a negative effect on the mothers' emotional state, their perception of parental self-image and, consequently, the early bond with the child—independent from the infants' gestational age at the time of the preterm delivery. The data underlined the importance of involving NICU nurses and clinicians in order to optimize the care for mothers immediately after the preterm birth and during the infant's hospitalization, taking into account psychological needs of mothers of both very preterm and moderately preterm infants.

The effect of a care program and social support on anxiety level in mothers of late preterm infants in Sistan and Baluchestan, Iran

Late and moderate preterm (LAMP) neonates are at risk of developing severe complications that can lead to anxiety in mothers. The aim of this study was to determine the effectiveness of a care program on the anxiety level of mothers with LAMP babies and to determine the effectiveness of the care program on the level of anxiety of new mothers in the presence of social support. This quasi-experimental study was conducted on 80 mothers whose late preterm infants were admitted to neonatal intensive care unit at Ali-ibn Abi Talib Hospital, Zahedan. Data were gathered between July 10 and October 13, 2016. The intervention group received the care program. Anxiety and social support were evaluated using the State-Trait Anxiety Inventory and Multidimensional Scale of Perceived Social Support (MSPSS), respectively. After receiving the intervention, the mean MSPSS was higher for the mothers in the intervention group (p = .0025). Additionally, they experienced less state anxiety 72 hours after discharge and 1 month after delivery (p < .0025). Regression analysis showed that mothers with higher social support were 39 percent more likely to be in the "no to moderate STAI" (<51) group. Perceived social support can mediate the effect of care programs on diminishing anxiety.

Outcomes of infants born near term: not quite ready for the "big wide world"?

Until recently, there has been a strongly held belief on the part of neonatal and pediatric clinicians that outcomes for infants born close to term are not different from those of babies born at full term. In the last decade, however, this assumption has been challenged by reports suggesting that this is not correct, and highlighting differences in morbidity and mortality both in the short and long term. This has led to development of new terminology to more accurately reflect the impact of immaturity associated with birth at 32-33 weeks (moderately preterm) and 34-36 weeks (late preterm) of gestation. These babies account for around 5-7% of all births and more than 75% of the preterm births in developed countries, so this new recognition of the associated increase in adverse outcomes may have a substantial impact on health care services. This review article will discuss the changing perceptions and concepts of gestational age in the preterm population, and explore the recent and emerging evidence around neonatal, early childhood, school-age, adolescent and adult outcomes for babies who are born moderately preterm and late preterm. It highlights important neonatal and childhood morbidities and will summarize associated health care, developmental and educational problems of affected children. The implications for the provision of ongoing primary and secondary health care, educational and social support to this large and heterogeneous group of individuals will be discussed.

Breastfeeding self-efficacy and breastmilk feeding for moderate and late preterm infants in the Family Integrated Care trial: a mixed methods protocol

BACKGROUND

Breastmilk is the ideal nutrition for preterm infants. Yet, breastmilk feeding rates among preterm infants are substantially lower than those of full-term infants. Barriers incurred through hospital care practices as well as the physical environment of the neonatal intensive care unit (NICU) can result in physical and emotional separation of infants from their parents, posing a substantial risk to establishing and maintaining breastfeeding. Additionally, current practitioner-focused care provision in the NICU can result in decreased breastfeeding self-efficacy (BSE), which is predictive of breastfeeding rates in mothers of preterm infants at 6 weeks postpartum.

METHODS

Family Integrated Care (FICare) integrates and supports parents to actively participate in the care of their infant while in the NICU. Nested within the broader FICare trial, we will conduct an explanatory sequential mixed methods study to investigate if FICare improves maternal BSE and rates of breastmilk feeding in moderate and late preterm infants at discharge from the NICU. In phase 1, we will calculate the mean difference between admission and discharge BSE scores for the intervention group. Mothers who score in the top and bottom 20th percentile of change scores will be invited to participate in a semi-structured telephone interview exploring maternal experiences with infant feeding in the NICU. We will conduct inductive thematic analysis to identify and describe the facilitators and barriers of FICare on maternal feeding experiences. Once data saturation is achieved and themes have been established, phase 2 will revisit the quantitative data to determine whether FICare was impactful on BSE and breastmilk feeding rates. Findings from the qualitative and quantitative phases will be integrated to determine how infant feeding experiences on FICare units work to improve or detract from maternal BSE and rates of breastmilk feeding.

DISCUSSION

FICare may help to improve maternal BSE and rates of breastmilk feeding in moderate and late preterm infants. Improved breastmilk feeding outcomes can have a substantial impact on overall infant health, developmental outcomes, and maternal-infant bonding and will help to improve long-term health outcomes for moderate and late preterm infants.

Outcomes Associated With Type of Milk Supplementation Among Late Preterm Infants

OBJECTIVE

To assess whether type of milk supplementation provided to breastfeeding late preterm infants was associated with hospital length of stay (LOS) or breastfeeding status at discharge.

DESIGN

Retrospective chart review.

SETTING

Tertiary care teaching hospital in the southern United States.

PARTICIPANTS

Late preterm infants 35 0/7 to 36 6/7 weeks gestational age (N = 183) admitted to the mother-baby unit between November 1, 2014, and October 31, 2016.

METHODS

The exposure of interest was type of milk supplementation, for example, expressed human milk, pasteurized donor human milk, and formula. Outcomes measured were LOS and breastfeeding status at discharge. Generalized Poisson regression models were used to compare LOS by type of milk supplementation. Modified Poisson regression models were used to estimate risk ratios and 95% confidence intervals for associations with breastfeeding status at discharge.

RESULTS

The LOS for breastfed infants supplemented with expressed human milk and/or pasteurized donor human milk did not differ significantly from exclusively breastfed infants who received no supplement. Exclusively formula-fed infants had longer LOS of 3.2 days compared with 2.6 days for exclusively breastfed infants (p = .001). Breastfed infants who received any formula supplementation were 16% less likely to continue breastfeeding until day of discharge compared with breastfed infants who received human milk supplementation (risk ratio = .84, 95% confidence interval [.77, .92]).

CONCLUSION

The high prevalence of supplementation among breastfeeding late preterm infants underscores the potential effect of type of milk supplementation on LOS and breastfeeding outcomes. Our findings suggest that human milk supplementation discourages transition to formula feeding before hospital discharge without increasing LOS.

Breastfeeding Characteristics of Late-Preterm Infants in a Kangaroo Mother Care Unit

OBJECTIVE

To describe the breastfeeding characteristics of late-preterm infants (LPIs) in a kangaroo mother care (KMC) unit.

MATERIALS AND METHODS

In a 20-bed KMC unit, the breastfeeding of 73 purposively-selected LPIs' (mean gestational age: 34.8 weeks) was observed once-off, using the Preterm Infant Breastfeeding Behavior Scale. Participants' mean age was 9.5 days, mean number of days in the unit was 3.1 days, and mean number of days breastfeeding was 7.5 on observation.

RESULTS

Only 13.7% of participants were directly breastfeeding without supplementary naso- or orogastric feeding/cup-feeding and 86.3% received supplementary cup-feeding of expressed breast milk. Most participants did not exhibit obvious rooting (83.5%) and although most latched-on (97.3%), those who did, latched shallowly (93%). The mean longest sucking burst was 18.8 (standard deviation: 10.5) and approximately half the participants swallowed repeatedly (53.4%). The mean breastfeeding session duration was 17.8 minutes, but most participants breastfed for less than 10 minutes (76.7%). No statistically significant differences in breastfeeding characteristics were detected between participants of different chronological ages. A general trend toward more mature behaviors in participants' breastfeeding for more days was present for many breastfeeding characteristics. More infants exhibited the most mature behavior for each breastfeeding characteristic when the environment was quiet, rather than noisy and disturbing, except for depth of latching (quiet: 0%, disturbance: 15.2%).

CONCLUSION

LPIs in this sample presented with subtle breastfeeding difficulties, highlighting their need for breastfeeding support. Further research is required to examine the effect of KMC on breastfeeding in LPIs.

Prevalence and Predictors of Breastfeeding After Childhood Abuse

OBJECTIVE

To describe the prevalence and predictors of breastfeeding intent and outcomes in women with histories of childhood maltreatment trauma (CMT), including those with posttraumatic stress disorder (PTSD).

DESIGN

Secondary analysis of a prospective observational cohort study of the effects of PTSD on perinatal outcomes.

SETTING

Prenatal clinics in three health systems in the Midwestern United States.

PARTICIPANTS

Women older than 18 years expecting their first infants, comprising three groups: women who experienced CMT but did not have PTSD (CMT-resilient), women with a history of CMT and PTSD (CMT-PTSD), and women with no history of CMT (CMT-nonexposed).

METHODS

Secondary analysis of an existing data set in which first-time mothers were well-characterized on trauma history, PTSD, depression, feeding plans, feeding outcomes, and several other factors relevant to odds of breastfeeding success.

RESULTS

Intent to breastfeed was similar among the three groups. Women in the CMT-resilient group were twice as likely to breastfeed exclusively at 6 weeks (60.5%) as women in the CMT-PTSD group (31.1%). Compared with women in the CMT-nonexposed group, women in the CMT-resilient group were more likely to exclusively breastfeed. Four factors were associated with increased likelihood of any breastfeeding at 6 weeks: prenatal intent to breastfeed, childbirth education, partnered, and a history of CMT. Four factors were associated with decreased odds of breastfeeding: African American race, PTSD, major depression, and low level of education (high school or less).

CONCLUSION

Posttraumatic stress disorder is more important than childhood maltreatment trauma history in determining likelihood of breastfeeding success. Further research on the promotion of breastfeeding among PTSD-affected women who have experienced CMT is indicated.

Integrative Review of Interventions to Promote Breastfeeding in the Late Preterm Infant

OBJECTIVE

To define the different breastfeeding interventions that promote breastfeeding exclusivity and duration in the late preterm infant and to synthesize findings from the published empirical literature on late preterm infant breastfeeding interventions.

DATA SOURCES

The databases CINAHL, Scopus, and PubMed were searched for primary research articles on breastfeeding interventions for late preterm infants. Inclusion criteria included original research studies in which authors examined a breastfeeding intervention or second-line strategy in a sample inclusive of but not necessarily limited to the gestational age range of 34 to 3667 weeks gestation, written in English, and published between 2005 and 2015.

STUDY SELECTION

Thirteen articles were identified, including five randomized controlled trials, three quasi-experimental studies, four descriptive studies, and one case study.

DATA EXTRACTION

Whittemore and Knafl's methodology guided this integrative review. Data extraction and organization occurred under the following headings: author and year, study design, level of evidence, purpose, sample, setting, results, limitations, recommendations, and intervention.

DATA SYNTHESIS

Studies on breastfeeding interventions were synthesized under four concepts within the Late Preterm Conceptual Framework: Physiologic Functional Status, Care Practices, Family Role, and Care Environment.

CONCLUSION

Most breastfeeding interventions within this integrative review had positive effects on exclusivity and duration of breastfeeding in the late preterm infant. However, second-line strategies had equivocal effects on exclusivity but had positive effects on duration. The positive effects of breastfeeding interventions on breastfeeding exclusivity and duration are highlighted in our results, and we point to the need for a focus on breastfeeding after the transition home for late preterm infants.

A qualitative study: Mothers of late preterm infants relate their experiences of community-based care

Purpose

In Alberta, the high occurrence of late preterm infants and early hospital discharge of mother-infant dyads has implications for postpartum care in the community. Shortened hospital stay and complexities surrounding the care of biologically and developmentally immature late preterm infants heighten anxiety and fears. Our descriptive phenomenological study explores mothers’ experience of caring for their late preterm infants in the community.

Methods

Eleven mothers were interviewed using a semi-structured interview guide. Interview transcripts were analysed using an interpretive thematic approach.

Findings

The mothers’ hospital experience informed their perspective that being a late preterm infant was not a “big deal,” and they tended to treat their infant as normal. “Feeding was really problem,” especially the variability in feeding effectiveness, which was not anticipated. Failing to recognize late preterm infants’ feeding distress exemplified lack of knowledge of feeding cues and tendencies to either rationalize or minimize feeding concerns. Public health nurses represent a source of informational support for managing neonatal morbidities associated with being late preterm; however, maternal experiences with public health nurses varied. Some nurses used a directive style that overwhelmed certain mothers. Seeing multiple public health nurses and care providers was not always effective, given inconsistent and contradictory guidance to care. These new and changing situations increased maternal anxiety and stress and influenced maternal confidence in care. Fathers, family, and friends were important sources of emotional support.

Conclusion

After discharge, mothers report their lack of preparation to meet the special needs of their late preterm infants. Current approaches to community-based care can threaten maternal confidence in care. New models and pathways of care for late preterm infants and their families need to be responsive to the spectrum of feeding issues encountered, limit duplication of services, and ensure consistent and effective care that parents will accept.

The Relationship Between Infant Feeding Outcomes and Maternal Emotional Well-being Among Mothers of Late Preterm and Term Infants: A Secondary, Exploratory Analysis

BACKGROUND

Late preterm birth is associated with lower rates of breastfeeding and earlier breastfeeding cessation than term birth.

PURPOSE

The objectives of this secondary analysis were to compare the incidence of exclusive breastfeeding after late preterm and term childbirth and to examine the association between infant feeding outcomes and maternal emotional well-being.

METHODS

Participants were 105 mother-infant dyads (54 late preterm and 51 term) at a southeastern US medical center. Face-to-face data collection and telephone follow-up occurred during 2009-2012.

RESULTS

Late preterm mothers were less likely to exclusively provide their milk than were term mothers during hospitalization. Feeding at 1 month did not differ between late preterm and term infants. Among late preterm mothers, (1) formula supplementation during hospitalization was associated with greater severity of anxiety than among those exclusively providing formula and (2) exclusive provision of human milk at 1 month was associated with less severe depressive symptoms than among those supplementing or exclusively formula feeding. Among term mothers, feeding outcome was not related to emotional well-being measures at either time point.

IMPLICATIONS FOR PRACTICE

Mothers of late preterm infants may particularly benefit from anticipatory guidance and early mental health screening, with integrated, multidisciplinary lactation teams to support these interrelated healthcare needs.

IMPLICATIONS FOR RESEARCH

Prospective research is critical to document women's intentions for infant feeding and how experiences with childbirth and the early postpartum period impact achievement of their breastfeeding goals.

Exploring the influence of psychosocial factors on exclusive breastfeeding in Bangladesh

Exclusive breastfeeding is a proven benefit for both mothers and infants and is, therefore, an important public health priority. Intimate partner violence (IPV) is regarded as one of the potential psychosocial risk factors that may negatively affect exclusive breastfeeding (EBF). This study aimed to explore the influence of psychosocial factors including IPV on EBF. Cross-sectional survey data was collected from October 2015 to January 2016 in Chandpur District of Bangladesh from 426 married women, aged 15-49 years, who had at least one child 6 months of age or younger. Multivariate logistic regression models were used in order to investigate whether women who experienced IPV after childbirth, as well as other risk factors such as postpartum depression (PPD) and childhood sexual abuse, were more likely to face difficulties with EBF compared with women who had not experienced these same risk factors. Whilst the initiation rate of breastfeeding was 99.3%, at the time of the woman's interview, the overall EBF rate had fallen to 43.7%. Based on the adjusted model, women who experienced physical IPV (AOR 0.17, 95% CI [0.07, 0.40]) and psychological IPV (AOR 0.51, 95% CI [0.26, 1.00]) after childbirth and women who reported childhood sexual abuse (AOR 0.32, 95% CI [0.13, 0.80]) and PPD (AOR 0.20, 95% CI [0.09, 0.44]) were significantly less likely to exclusively breastfeed their infants than those who had not reported these experiences. Moreover, women with an intended pregnancy and high social support exhibited a higher likelihood of EBF. Our results suggest that preventing or reducing the occurrence of physical IPV, PPD and childhood sexual abuse may improve the EBF duration. Support from family members can assist in this process.

Feasibility and Acceptability of Two Complementary and Alternative Therapies for Perceived Insufficient Milk in Mothers of Late Preterm and Early Term Infants

Background: Complementary and alternative medicine (CAM) could be one option to address perceived insufficient milk (PIM), but there are few data comparing the effectiveness, acceptability, and safety of various CAM therapies. The purpose of this study was to describe and compare, among women delivering at 34-376/7 weeks, the feasibility and acceptability of two CAM interventions for treatment of PIM: (1) a meditation/relaxation intervention via an MP3 (Apple iPod Shuffle©) player and (2) a commercially available combination-blend herbal supplement (Motherlove: More Milk Plus Alcohol Free®). Materials and Methods: After randomization, over 9 days, women received three home visits from a lactation consultant, recorded pre/post intervention test weights and expressed milk volume, tracked daily breastfeeding behavior, and completed an end-of-study interview about the interventions. Women in each group were offered the other group's intervention on study day 9. Breastfeeding status and intervention continuation were assessed at 2 months. Results: Of 183 women screened, 11 were eligible, enrolled into, and completed the 9-day trial. Six women were randomized to the herbal supplement and 5 to meditation. One participant (meditation) stopped breastfeeding on study day 8. At 2 months, 3 of 6 women assigned to the herbal supplement and 3 of 5 women assigned to meditation were still breastfeeding; 1 (herbal supplement) was exclusively breastfeeding. Most participants were adherent to the prescribed protocols for both interventions. Interventions were generally perceived as safe, with benefits not necessarily related to increased milk supply. Conclusion: Mothers of late preterm and early term infants who had PIM found the CAM interventions acceptable and safe. The effect of CAM therapies on breastfeeding outcomes, with and without in-home lactation assistance, requires further investigation.

The interaction of personality profile and lactation differs between mothers of late preterm and term neonates

Late preterm birth, a rapidly growing segment of premature deliveries, has the potential to cause deleterious effects on women's psycho-emotional experience of labor and the establishment of successful lactation. We compared personality traits by the Lüscher Color Test, the mother-to-infant bonding attitudes by the Mother-to-Infant Bonding Scale (MIBS) and lactation outcome, between mothers of late preterm and at term infants. Our results indicated that mothers idealize their condition and wish to enjoy this magic and extraordinary time in spite of feeling stressed. However, late preterm mothers feel too sad and distressed to relax in their own space after the premature birth event. In addition, their total MIBS score (mean ± SD) was significantly higher (1.364 versus 0.581; p 0.026), as related subscales: Dislike (p 0.005) and Disappointed (p 0.012). Finally, they significantly reduced breastfeeding rates from discharge (p < 0.0001), to the first (p < 0.001), the third (p = 0.002) and sixth postnatal month (p = 0.0002). We concluded that there is a relation between unconscious deep stress along with bonding limits of late preterm new mothers and impaired breastfeeding initiation and duration.

A Test of Kangaroo Care on Preterm Infant Breastfeeding

OBJECTIVE

To test the effects of kangaroo care (KC) on breastfeeding outcomes in preterm infants compared with two control groups and to explore whether maternal-infant characteristics and the mother's choice to use KC were related to breastfeeding measures.

DESIGN

Secondary analysis of a multisite, stratified, randomized three-arm trial. The treatment groups used KC, auditory-tactile-visual-vestibular (ATVV) intervention, or received preterm infant care information.

SETTING

Neonatal intensive care units from 4 hospitals in the United States from 2006 to 2011.

PARTICIPANTS

Racially diverse mothers (N = 231) and their preterm infants born weighing less than 1,750 g.

METHODS

Mothers and their infants were enrolled once the infants were no longer critically ill, weighed at least 1,000 g, and could be safely held outside the incubator by parents. Participants were instructed by study nurses; those allocated to the KC or ATVV groups were asked to engage in these interactions with their infants for a minimum of 3 times a week in the hospital and at home until their infants reached age 2 months adjusted for prematurity.

RESULTS

Feeding at the breast during hospitalization, the duration of postdischarge breastfeeding, and breastfeeding exclusivity after hospital discharge did not differ statistically among the treatment groups. Regardless of group assignment, married, older, and more educated women were more likely to feed at the breast during hospitalization. Mothers who practiced KC, regardless of randomly allocated group, were more likely to provide their milk than those who did not practice KC. Breastfeeding duration was greatest among more educated women.

CONCLUSION

As implemented in this study, assignment to the KC group did not appear to influence the measured breastfeeding outcomes.

Recommendations for mental health professionals in the NICU

This article describes recommended activities of social workers, psychologists and psychiatric staff within the neonatal intensive care unit (NICU). NICU mental health professionals (NMHPs) should interact with all NICU parents in providing emotional support, screening, education, psychotherapy and teleservices for families. NMHPs should also offer educational and emotional support for the NICU health-care staff. NMHPs should function at all levels of layered care delivered to NICU parents. Methods of screening for emotional distress are described, as well as evidence for the benefits of peer-to-peer support and psychotherapy delivered in the NICU. In the ideal NICU, care for the emotional and educational needs of NICU parents are outcomes equal in importance to the health and development of their babies. Whenever possible, NMHPs should be involved with parents from the antepartum period through after discharge.

Pattern of mother-child feeding interactions in preterm and term dyads at 18 and 24 months

Literature on mother-child feeding interactions during the transition to self-feeding in preterm populations is lacking, particularly through observational methods. The present research study aims to look at the longitudinal patterns of mother-toddler feeding interactions, comparing preterm and full term dyads. To this end, a multi-method approach was used to collect data from 27 preterm to 20 full-term toddlers and their mothers. For each dyad, mother-child interactions were observed during the snack time at 18 and 24 months of age and then assessed through the Italian version of the Feeding Scale. Higher scores on the scale indicate a less healthy pattern of interaction. Additionally, at both points in time, mothers completed the BDI-II questionnaire as a screen for maternal depression and the child's developmental stage was assessed using the Griffiths Scales. A series of repeated measures Analysis of Variances were run to detect differences in feeding interactions between the two groups at the time of assessment. Our results show that preterm dyads report overall higher levels of maternal negative affection, interactional conflicts, and less dyadic reciprocity during the meal compared to full-term dyads. Additionally, longitudinal data show that dyadic conflict decreases in both groups, whereas the child's food refusal behaviors increase in the preterm group from 18 to 24 months. No differences were reported for both the BDI-II and the child's development for the two groups. The results reveal that regardless of maternal depression and the child's developmental stage, the two groups show different trajectories in the pattern of feeding interactions during the transition to self -feeding, at 18 and 24 months, with overall less positive interactions in preterm mother-child dyads.

Acceptability and feasibility of a breast milk expression education and support intervention in mothers of preterm infants

PURPOSE

A pilot study was conducted to assess the acceptability and feasibility of a breast milk expression education and support intervention in mothers of preterm infants and study procedures.

SUBJECTS

Forty mothers of preterm infants born at less than 30 weeks of gestation.

DESIGN

Pilot randomized controlled trial.

METHODS

Mothers of preterm infants were randomly allocated to the breast milk expression education and support intervention or standard care. The experimental intervention encompassed a breast milk expression education session on 7 themes, telephone follow-up, and telephone helpline.

MAIN OUTCOME MEASURES

Data related to the acceptability and feasibility of the intervention and study procedures were collected throughout the study. At the end of the study, mothers allocated to the experimental intervention completed a self-report questionnaire assessing the acceptability of each of the intervention components.

RESULTS

It was feasible to recruit 70% of eligible mothers and retain 83% of mothers who consented to participate in the study. Mothers reported that all the intervention components were appropriate and effective in supporting their breast milk production. Although the reliability of the data collection method was demonstrated, the fidelity of the telephone follow-up faced some challenges.

CONCLUSIONS

Both the intervention and study procedures were acceptable and feasible. Improvements related to the fidelity of the intervention would ensure the feasibility and internal validity of a larger-scale trial.

Improvements in staff quality of work life and family satisfaction following the move to single-family room NICU design

OBJECTIVE

The purpose of this study was to determine whether there were differences in staff quality of work life and parent satisfaction when a neonatal intensive care unit moved from an open-bay design to a single-room model of care.

DESIGN

This descriptive study measured staff quality of work life and family satisfaction before and at 2 time periods after the relocation of a perinatal centre and the introduction of single-family room care. Differences in work life quality and satisfaction were determined using 2-sample t-tests.

RESULT

There were improvements in staff quality of work life and family satisfaction at both time periods following the move.

CONCLUSION

Lessons learned may be of value to other units considering such a move. A neonatal intensive care unit designed to contribute to parental and staff well-being is a model to be considered for future neonatal designs.

A comparison between late preterm and term infants on breastfeeding and maternal mental health

The objective of this study was to compare breastfeeding, postpartum mental health, and health service utilization between a group of late preterm (LP) maternal infant pairs and term counterparts. Data was drawn from a prospective community-based cohort in Calgary, Alberta. Bivariate and multivariable analyses were performed. LP infants were more likely to have had a longer median length of stay after birth (P < 0.001) and a higher re-hospitalization rate at 4-months (P < 0.001) compared to term infants. Mothers of LP infants were more likely to report immediate breastfeeding difficulties (P < 0.001) and earlier cessation of breastfeeding at 4-months postpartum (P = 0.008). Multivariable analyses revealed that LP status was an independent risk factor for excessive symptoms of maternal anxiety (OR = 2.07; 95 % CI = 1.08,3.98), but not for depression, stress, or low parenting morale. LP infants and their families are a vulnerable population with unique developmental trajectories. Further longitudinal research is required.

Is maternal depressive symptomatology effective on success of exclusive breastfeeding during postpartum 6 weeks?

AIM

The aim of this prospective study was to examine the relationship between success of exclusive breastfeeding and postpartum depressive symptomatology. Our hypothesis was that mothers with depressive symptoms initially fail exclusive breastfeeding.

SUBJECTS AND METHODS

One hundred ninety-seven mothers were enrolled in the study. The participants were interviewed twice. The first visit was within the first 48 hours after birth. The Edinburgh Postnatal Depression Scale (EPDS) was completed by the participants. The second interview was performed at 6 weeks. Participants answered questions regarding methods of breastfeeding for 6 weeks, any methodological problems, and nipple pain. The EPDS was again completed by the participants at 6 weeks. All newborns were term infants.

RESULTS

All the participants were divided into two groups: exclusive breastfeeding and mixed-feeding (partial breastfeeding and/or bottle feeding). Both groups were compared in terms of features, such as mode of delivery, parity, prevalence of depressive symptomatology (at 48 hours and 6 weeks), and delayed onset of lactation within the first 48 hours. Statistical significance was found for only three variables: delayed onset of lactation within the first 48 hours, gestational age, and the problems related to breastfeeding methods.

CONCLUSIONS

Clinicians should pay special attention to any lactation difficulty during the first week postpartum. Early lactation difficulties are associated with greater risk of early termination of breastfeeding and lower breastfeeding success.

Late preterm birth: a review of medical and neuropsychological childhood outcomes

Late preterm (LP) birth (34 0/7 - 36 6/7 weeks' gestation) accounts for nearly three-fourths of all preterm births, making this population a sizeable public health concern. The immature fetal development associated with LP delivery increases the risk of mortality and short-term medical complications. Which combination of maternal, fetal, or neonatal risk factors may be most critical has only recently begun to be addressed, and whether LP birth's disruptive impact on brain development will exert adverse effects on neuropsychological functioning in childhood and adolescence has been understudied. Early data have shown a graded response, with LP children often functioning better than very preterm children but worse than term children, and with subtle intellectual and neuropsychological deficits in LP children compared with healthy children born at term gestational age. Further characterization of the neuropsychological profile is required and would be best accomplished through prospective longitudinal studies. Moreover, since moderate and LP births result in disparate medical and psychological outcomes, the common methodology of combining these participants into a single research cohort to assess risk and outcome should be reconsidered. The rapidly growing LP outcomes literature reinforces a critical principle: fetal development occurs along a dynamic maturational continuum from conception to birth, with each successive gestational day likely to improve overall outcome.

NEONATAL OUTCOMES FOLLOWING LATE PRETERM BIRTH

It is well recognised that birth before 32 weeks of gestation is associated with substantial neonatal morbidity and mortality and these risks have been extensively reported. The focus of perinatal research for many years has therefore been very preterm and extremely preterm delivery, since the likelihood and severity of adverse neonatal outcomes are highest within this group. In contrast, until recently, more mature preterm infants have been understudied and indeed, almost ignored by researchers.

Mother infant relationship and bonding myths and facts

Mother-infant relationship has always interested researchers worldwide. This paper reviews the development of the concept of mother infant bonding through the years.

Breastfeeding the premature infant and nursing implications

Research indicates that feeding preterm infants at the breast is physiologically less stressful than bottle-feeding. Poor sucking reflexes make it difficult to initiate breastfeeding for these high-risk infants. Mothers need to understand the difficulties of breastfeeding, as well as the advantages for herself and her baby. It is important for nurses to be well educated on how preterm infants are breastfed and how to best support the mother through her experience. The nurse must focus on caring for the infant as well as fostering the mother-infant connection to promote breastfeeding. A mother will need continual support, encouragement, and advice from the nurse, while teaching her baby how to breastfeed.

Emotional responses of mothers of late-preterm and term infants

OBJECTIVE

To compare the emotional responses of mothers of late-preterm infants (34 0/7 to 36 6/7 weeks gestation) with those of mothers of full-term infants.

DESIGN

A mixed method comparative study.

SETTING

A southeastern tertiary academic medical center postpartum unit.

PARTICIPANTS

Sixty mothers: 29 mothers of late-preterm infants and 31 mothers of full-term infants.

METHODS

Measures of maternal emotional distress (four standardized measures of anxiety, postpartum depression, posttraumatic stress symptoms, and worry about infant health) and open-ended semistructured maternal interviews were conducted in the hospital following birth and by phone at one month postpartum.

RESULTS

Mothers of late-preterm infants experienced significantly greater emotional distress immediately following delivery, and their distress levels continued to be higher at one month postpartum on each of the standardized measures. Mothers of late-preterm infants also discussed the altered trajectories in their birth and postpartum experiences and feeling unprepared for these unexpected events as a source of ongoing emotional distress.

CONCLUSION

Mothers of late-preterm infants have greater emotional distress than mothers of term infants for at least one month after delivery. Our findings suggest that it may not be a single event that leads to different distress levels in mothers of late-preterm and full-term infants but rather the interaction of multiple alterations in the labor and delivery process and the poorer-than-expected infant health outcomes. In the future, researchers need to examine how and when mothers' emotional responses change over time and how their responses relate to parenting and infant health and development.
