Massage therapy by mothers enhances the adjustment of circadian rhythms to the nocturnal period in full-term infants

Developmental care pathway for hospitalised infants with CHD: on behalf of the Cardiac Newborn Neuroprotective Network, a Special Interest Group of the Cardiac Neurodevelopmental Outcome Collaborative

Infants and children born with CHD are at significant risk for neurodevelopmental delays and abnormalities. Individualised developmental care is widely recognised as best practice to support early neurodevelopment for medically fragile infants born premature or requiring surgical intervention after birth. However, wide variability in clinical practice is consistently demonstrated in units caring for infants with CHD. The Cardiac Newborn Neuroprotective Network, a Special Interest Group of the Cardiac Neurodevelopmental Outcome Collaborative, formed a working group of experts to create an evidence-based developmental care pathway to guide clinical practice in hospital settings caring for infants with CHD. The clinical pathway, "Developmental Care Pathway for Hospitalized Infants with Congenital Heart Disease," includes recommendations for standardised developmental assessment, parent mental health screening, and the implementation of a daily developmental care bundle, which incorporates individualised assessments and interventions tailored to meet the needs of this unique infant population and their families. Hospitals caring for infants with CHD are encouraged to adopt this developmental care pathway and track metrics and outcomes using a quality improvement framework.

Evidence-Based Consensus Recommendations for Skin Care in Healthy, Full-Term Neonates in India

Purpose

Neonatal skin care practices guided by personal experience and preferences might be substantially different across different hospital settings. The aim of this consensus recommendation is to provide clinical practice guidance to healthcare practitioners on evidence-based neonatal skin care practices from delivery-to-discharge, in hospital settings.

Patients and Methods

A Scientific Advisory Board meeting on "Evidence-based Neonatal Skin Care Practices and Protocols" was held in December 2020 with an expert panel comprising neonatologists, pediatricians, obstetricians and gynecologists and pediatric dermatologist. Comprehensive literature search was performed up to 23 March 2021 using PubMed and Google Scholar to retrieve relevant evidence.

Results

Recommendations were developed on critical aspects of skin care in healthy full-term neonates including cleansing at birth, skin-to-skin care, cord care, diaper area care, initial and routine bathing, cleansers and emollients use, and criteria to choose appropriate skin care products. Recommendations include inclusion of skin assessment in routine neonatal care, first bath timing after cardio-respiratory and thermal stabilization, 6-24 hours after birth; bathing with water alone or adding a mild liquid cleanser could be considered appropriate as it does not impact the developing skin barrier; use of emollients is recommended for neonates with higher risk of development of eczema to maintain and enhance skin barrier function and integrity; and inclusion of skin care advice in neonatal discharge checklist. Importance of rigorous quality control, high-quality clinical trials for assessment of baby products, usage of products that are formulated appropriately for newborns, and full label transparency for baby products were highlighted. The panel identified gaps in literature and discussed the scope for future research.

Conclusion

These recommendations may help to standardize evidence-based skin care for healthy full-term neonates in Indian hospital settings to improve the quality of care that neonates receive in hospital and facilitate improvement in overall neonatal health outcomes.

Designing artificial circadian environments with multisensory cares for supporting preterm infants' growth in NICUs

Previous studies suggest the importance of stable circadian environments for fetuses to achieve sound physiology and intrauterine development. This idea is also supported by epidemiological and animal studies, in which pregnant females exposed to repeated shifting of light-dark cycles had increased rates of reproductive abnormalities and adverse pregnancy outcomes. In response to such findings, artificial circadian environments with light-dark (LD) cycles have been introduced to NICUs to promote better physical development of preterm infants. Such LD cycles, however, may not be fully effective for preterm infants who are less than 30 weeks gestational age (WGA) since they are too premature to be adequately responsive to light. Instead, circadian rhythmicity of incubated preterm infants less than 30 WGA may be able to be developed through stimulation of the non-visual senses such as touch and sound.

The positive effect of mother-performed infant massage on infantile eczema and maternal mental state: A randomized controlled trial

Objective

To observe the influence of MPIM on infantile eczema, quality of life, growth and maternal mental state.

Methods

This trial was a randomized controlled study. Sixty-six full-term infants with eczema were randomly divided into eczema control group (EC group, n = 33) and eczema with MPIM group (EM group, n = 33), along with healthy full-term infants in the healthy control group (HC group, n = 31). The mothers in the EC group received the instruction of routine care, while the mothers in the EM group applied massage on the infants plus receiving the same instruction of the routine care. HC group received none of any specific intervention. Data were collected in the three groups at the baseline and at the end of 2- and 5-month intervention. Before and at the end of 2-month intervention, the following indexes were investigated in infants including the growth indexes, eczema area severity index (EASI), infantile dermatitis quality of life index (IDQOL). And the scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were investigated in mothers at the same timepoints. At the end of 5-month intervention, the infants' growth and relapse condition of eczema were observed.

Results

Overall, 31 cases in HC group, 31 in EC group and 32 in EM group were included for data analysis. There were no significant differences in the indexes of infantile growth among the three groups (all P >0.05). The scores of EASI and IDQOL significantly lowered (both P < 0.001) in EC group following the instruction of routine care, along with reduced maternal scores of SAS and SDS (both P < 0.05). Compared with the EC group, the EM group showed significantly lower scores of EASI and IDQOL (both P < 0.001) and lower relapse rate (P < 0.01) in infants with eczema, along with significantly lower scores of SAS and SDS in mothers (both P < 0.01). Moreover, none of obvious adverse reaction was reported following MPIM, to which most of the mothers could adhere.

Conclusion

MPIM could effectively promote the remission of infantile eczema and reduce its relapse, along with relieving maternal anxiety and depression mood.

Effect of whole-body massage on growth and neurodevelopment in term healthy newborns: A systematic review

Background

Infant massage is commonly practiced in many parts of the world. However, the effectiveness of this intervention has not been reviewed for term, healthy newborns.

Methods

This systematic review of randomized and quasi-randomized controlled trials assessed the effect of whole-body massage with or without oil, compared to no massage in term healthy newborns. Key outcomes were neonatal mortality, systemic infections, growth, behaviour (crying or fussing time, sleep duration), and neurodevelopment. We searched MEDLINE via PubMed, Cochrane CENTRAL, EMBASE, and CINAHL (updated till November 2021), and clinical trials databases and reference lists of retrieved articles. Two authors separately evaluated the risk of bias, extracted data, and synthesized effect estimates using mean difference (MD) and standardized mean difference (SMD). The GRADE approach was used to assess the certainty of evidence.

Results

We included 31 randomized and quasi-randomized trials involving 3860 participants. Infant massage was performed by different care providers starting in the neonatal period and continuing for 1-2 months in most studies. Thirteen studies reported the use of oil with body massage. No study reported neonatal mortality or systemic infections. Meta-analyses suggested that whole-body massage may increase infant length at the end of the intervention period (median assessment age 6 weeks; mean difference (MD) = 1.6 cm, 95% confidence interval (CI) = 1.4 to 1.7 cm; low certainty evidence), but the effect on weight (MD = 340 g, 95% CI = 240 to 441 g), head circumference (MD = 0.8 cm, 95% CI = 0.6 to 1.1 cm), sleep duration (MD = 0.62 hours/d, 95% CI = 0.12 to 1.12 hours/d) and bilirubin levels (MD = -31.8 mmol/L or -1.8 mg/dL, 95% CI = -23.5 to -40.0 mmol/L) was uncertain. The effect on crying/fussing time at median 3 months of age, sleep duration at 6 months of age, weight, length, and head circumference at 6-12 months follow-up, and neurodevelopment outcomes, both at the end of the intervention period and follow-up was uncertain.

Conclusions

Whole-body massage may improve the infant length at the end of the intervention period (median age 6 weeks, range 1-6 months) but the effect on other short- or long-term outcomes is uncertain. There is a need for further well-designed trials in future.

Using complexity science to understand the role of co-sleeping (bedsharing) in mother-infant co-regulatory processes

Human infants spend most of their time sleeping, but over the first few years of life their sleep becomes regulated to coincide more closely with adult sleep (Galland et al., 2012; Paavonen et al., 2020). Evidence shows that co-sleeping played a role in the evolution of infant sleep regulation, as it is part of an ancient behavioral complex representing the biopsychosocial microenvironment in which human infants co-evolved with their mothers through millions of years of human history (Ball, 2003; McKenna 1986, 1990). This paper is a conceptual, interdisciplinary, integration of the literature on mother-infant co-sleeping and other mother-infant co-regulatory processes from an evolutionary (biological) perspective, using complexity science. Viewing the mother-infant dyad as a "complex adaptive system" (CAS) shows how the CAS fits assumptions of regulatory processes and reveals the role of the CAS in the ontogeny of mother-infant co-regulation of physiological (thermoregulation, breathing, circadian rhythm coordination, nighttime synchrony, and heart rate variability) and socioemotional (attachment and cortisol activity) development.

Development of the Ontogenetic Self-Regulation Clock

To date, there is no overarching proposition for the ontogenetic-neurobiological basis of self-regulation. This paper suggests that the balanced self-regulatory reaction of the fetus, newborn and infant is based on a complex mechanism starting from early brainstem development and continuing to progressive control of the cortex over the brainstem. It is suggested that this balance occurs through the synchronous reactivity between the sympathetic and parasympathetic systems, both which originate from the brainstem. The paper presents an evidence-based approach in which molecular excitation-inhibition balance, interchanges between excitatory and inhibitory roles of neurotransmitters as well as cardiovascular and white matter development across gestational ages, are shown to create sympathetic-parasympathetic synchrony, including the postnatal development of electroencephalogram waves and vagal tone. These occur in developmental milestones detectable in the same time windows (sensitive periods of development) within a convergent systematic progress. This ontogenetic stepwise process is termed "the self-regulation clock" and suggest that this clock is located in the largest connection between the brainstem and the cortex, the corticospinal tract. This novel evidence-based new theory paves the way towards more accurate hypotheses and complex studies of self-regulation and its biological basis, as well as pointing to time windows for interventions in preterm infants. The paper also describes the developing indirect signaling between the suprachiasmatic nucleus and the corticospinal tract. Finally, the paper proposes novel hypotheses for molecular, structural and functional investigation of the "clock" circuitry, including its associations with other biological clocks. This complex circuitry is suggested to be responsible for the developing self-regulatory functions and their neurobehavioral correlates.

Pediatric Massage Therapy Research: A Narrative Review

This narrative review on pediatric massage literature from the last decade suggests that massage therapy has positive effects on several pediatric conditions. These include preterm infant growth, psychological problems including aggression, gastrointestinal problems including constipation and diarrhea, painful conditions including burns and sickle cell, muscle tone disorders including cerebral palsy and Down syndrome, and chronic illnesses including diabetes, asthma cancer, and HIV. Potential underlying mechanisms for the massage therapy effects include increased vagal activity and decreased stress hormones. Limitations of the literature include the need for more randomized controlled trials, longitudinal studies, and underlying mechanism studies.

Benefits of a bedtime routine in young children: Sleep, development, and beyond

This paper presents a conceptual model and reviews the empirical evidence to support a nightly bedtime routine as a key factor in the promotion of not only healthy sleep, but also of broad development and wellbeing in early childhood. A bedtime routine embodies the characteristics of nurturing care and early child stimulation, which are deemed to be essential for positive outcomes, especially for at-risk children. Furthermore, common, adaptive components of a bedtime routine can contribute to an array of positive developmental outcomes beyond improved sleep, inclusive of language development, literacy, child emotional and behavioral regulation, parent-child attachment, and family functioning, among other outcomes. These bedtime routine components include activities in the broad domains of nutrition (e.g., feeding, healthy snack), hygiene (e.g., bathing, oral care), communication (e.g., reading, singing/lullabies) and physical contact (e.g., massage, cuddling/rocking). A bedtime routine can provide multiple benefits to child and family functioning at a time of day that many parents are present with their children. Although additional research on hypothesized routine-related child outcomes and mechanisms of action are needed, promoting a bedtime routine may be a feasible and cost-effective method to promote positive early childhood development worldwide, particularly for socioeconomically disadvantaged and other at-risk young children.

Systematic Review of Skin-to-Skin Care for Full-Term, Healthy Newborns

OBJECTIVE

To determine the effect of skin-to-skin mother-infant holding, touch, and/or massage on full-term, healthy newborns and their primary caregivers.

DATA SOURCES

A seven-member scientific advisory panel searched the databases PubMed, CINAHL, and Scopus using the search terms massage, skin-to-skin contact, kangaroo care, touch, therapeutic touch, and full-term newborns for research with human participants published in English with no date parameters.

STUDY SELECTION

The initial search yielded 416 articles. After reviewing titles and retaining only articles that met the review criteria, 280 articles remained. The panel co-chairs reviewed and discussed the abstracts of these articles and retained 90 for review.

DATA EXTRACTION

Each article was assigned to one panel member and one co-chair for review. Members of the panel met via teleconference to present articles and to determine whether they had scientific merit and addressed the research question. Articles that did not meet these standards were eliminated. Forty articles included relevant evidence: 33 articles on skin-to-skin holding and 7 on infant massage.

DATA SYNTHESIS

We created a table that included the purpose, design, and findings of each study. This information was synthesized into a feasibility report by the co-chairs.

CONCLUSION

Evidence supports recommendations for skin-to-skin care for all full-term, healthy newborns. Although there is inadequate evidence to recommend massage as standard care for all newborns, massage has been shown to help consolidate sleep patterns and reduce jaundice.

Review and Critical Analysis of Massage Studies for Term and Preterm Infants

PURPOSE

To review and analyze studies evaluating the effects of massage on term and preterm infants.

DESIGN

A systematic review of literature.

RESULTS

Benefits of massage for term infants are: improved weight gain, growth, and sleep and decreased hyperbilirubinemia. Benefits for preterm infants are: improved weight gain, decreased response to pain, and increased interactions with parents. However, the few studies use different interventions related to timing and number of massages, and the outcomes vary among studies. There is not enough evidence to support the use of massage for term and preterm infants, but massage may be considered on a case-by-case basis.

Interactions during feeding with mothers and their infants with symptoms of gastroesophageal reflux

OBJECTIVES

To examine whether maternal-child interaction during feedings was suboptimal in dyads in which the infant had gastroesophageal reflux disease (GERD) and to compare massage therapy to a nonmassage therapy sham treatment in improving the mother-child interaction in these dyads.

DESIGN

In this randomized, controlled pilot study, infants received massage therapy (n=18) or a nonmassage touch/holding sham treatment (n=18). Mothers, data collectors, and the investigator who scored the feeding observations were blinded to group assignment.

SETTINGS/LOCATION

Dyads were recruited from pediatric care providers in the Denver metropolitan area and online advertisements at the University of Colorado. Treatments were given in the home of the dyad.

PARTICIPANTS

Healthy infants, born at 38-42 weeks gestational age, were 5-10 weeks of age at enrollment; had a score of at least 16 on the Infant Gastroesophageal Reflux Questionnaire-Revised; and were diagnosed with GERD by their pediatric provider. Mothers were English speaking and at least 18 years of age.

INTERVENTIONS

Treatments were given for 30 minutes twice weekly for 6 weeks. A certified infant massage therapist administered massage, and a registered nurse or physical therapist experienced with infants administered the control treatment.

OUTCOME MEASURES

Maternal and infant scores on the Nursing Child Assessment of Feeding Scale (NCAFS).

RESULTS

NCAFS scores were significantly lower than national norms. Small to moderately sized effects showing improvement in the massage group relative to the nonmassage group were seen for Sensitivity to Cues, Social-Emotional Growth Fostering, Cognitive Growth Fostering, and Clarity of Cues (Cohen d) and ranged from 0.24 to 0.56.

CONCLUSIONS

Mothers and infants with GERD experience significantly worse interactions than those without GERD. Massage given twice weekly by a professional trended toward improved interaction during feeding. Daily maternal administration of massage may have a positive effect on the relationship.

Benefits of massage therapy for infants with symptoms of gastroesophageal reflux disease

OBJECTIVES

This randomized controlled pilot trial was conducted to evaluate the clinical efficacy of massage therapy (MT) for relief of symptoms of gastroesophageal reflux disease (GERD). The hypothesis was that, when compared to infants who received nonmassage therapy, infants who received MT would display fewer GERD symptoms, greater weight gain, greater amount of sleep, lower cortisol levels before and after treatment, and lower daily (area under the curve [AUC]) cortisol secretion.

METHODS

Participants were 36 infants born at term, 4-10 weeks of age at enrollment, healthy except for a diagnosis of GERD by their pediatrician, and with a score of at least 16 on the Infant Gastroesophageal Reflux Questionnaire-Revised (I-GERQ-R). Infants were randomized to receive either MT or a nonmassage sham treatment in their homes for 30 min twice a week for 6 weeks. Data collectors and parents were blind to study condition.

RESULTS

GERD symptoms decreased in both groups and weight increased. Pretreatment salivary cortisol levels decreased significantly over time in the massage group while increasing in the nonmassage group. Daily cortisol level also decreased in the massage group and increased in the nonmassage group, but the difference was not significant.

CONCLUSIONS

MT administered by a professional therapist did not affect symptoms of GERD differently than a sham treatment but did decrease infant stress as measured by cortisol. Research focusing on stress reduction in infants with GERD and multimodal treatments addressing GERD symptoms may yield the most effective treatment.

Treatment of tactile impairment in young children with autism: results with qigong massage

Background

Following the inclusion of sensory abnormalities in the diagnostic criteria for autism, evidence has emerged showing that tactile abnormalities in young children with autism are severe, universally present, and directly related to delay of early self-regulation milestones required for social development. Parent touch is the most effective means of stimulating early self-regulation, yet parents of children with autism avoid touch because their children respond abnormally to it. This suggests that tactile abnormalities pose a barrier to parent touch in autism, and that treatment of tactile abnormalities may improve developmental outcomes. We have developed a qigong massage treatment for tactile abnormalities in young children with autism. Here we evaluate whether tactile abnormalities decrease following treatment, and whether treatment results in improved self-regulatory outcomes.

Methods

We retrospectively analyzed our qigong massage database for treatment effect on tactile abnormalities, self-regulatory delay, and parenting stress. Five-month interval data were available for 129 children with autism aged 3–6 years. Of these 129, 97 received treatment and 32 were in the wait-list control condition. There were no differences between treatment and control groups by age, gender, or severity of tactile impairment.

Results

Treatment resulted in significant decreases of tactile impairment, self-regulatory delay, and parenting stress (p < .001 on all paired t-tests); mean decreases were 25.5%, 24.5%, and 35.8%, respectively. Results were significant compared to controls [F(3,122) = 11.27, p < .001]. In the pretreatment data, tactile impairment was directly related to self-regulatory delay; post-treatment, both variables decreased proportionally.

Conclusion

Results demonstrate that tactile impairment in young children with autism is treatable with a qigong massage protocol. The direct relationship between tactile impairment and self-regulatory delay pretreatment, and the proportional decrease of both following treatment, suggest that tactile impairment is a cause of self-regulatory delay, and that qigong massage is a promising avenue to improve developmental outcomes in autism.

Massage for promoting mental and physical health in typically developing infants under the age of six months

BACKGROUND

Infant massage is increasingly being used in the community with babies and their primary caregivers. Anecdotal reports suggest benefits for sleep, respiration and elimination, the reduction of colic and wind, and improved growth. Infant massage is also thought to reduce infant stress and promote positive parent-infant interaction.

OBJECTIVES

The aim of this review was to assess whether infant massage is effective in promoting infant physical and mental health in low-risk, population samples.

SEARCH METHODS

Relevant studies were identified by searching the following electronic databases up to June 2011: CENTRAL; MEDLINE; EMBASE; CINAHL; PsycINFO; Maternity and Infant Care; LILACS; WorldCat (dissertations); ClinicalTrials.gov; China Masters' Theses; China Academic Journals; China Doctoral Dissertations; China Proceedings of Conference. We also searched the reference lists of relevant studies and reviews.

SELECTION CRITERIA

We included studies that randomised healthy parent-infant dyads (where the infant was under the age of six months) to an infant massage group or a 'no-treatment' control group. Studies had to have used a standardised outcome measure of infant mental or physical development.

DATA COLLECTION AND ANALYSIS

Mean differences (MD) and standardised mean differences (SMD) and 95% confidence intervals (CIs) are presented. Where appropriate, the results have been combined in a meta-analysis using a random-effects model.

MAIN RESULTS

We included 34 studies, which includes one that was a follow-up study and 20 that were rated as being at high risk of bias.We conducted 14 meta-analyses assessing physical outcomes post-intervention. Nine meta-analyses showed significant findings favouring the intervention group for weight (MD -965.25 g; 95% CI -1360.52 to -569.98), length (MD -1.30 cm; 95% CI -1.60 to -1.00), head circumference (MD -0.81 cm; 95% CI -1.18 to -0.45), arm circumference (MD -0.47 cm; 95% CI -0.80 to -0.13), leg circumference (MD -0.31 cm; 95% CI -0.49 to -0.13), 24-hour sleep duration (MD -0.91 hr; 95% CI -1.51 to -0.30), time spent crying/fussing (MD -0.36; 95% CI -0.52 to -0.19), deceased levels of blood bilirubin (MD -38.11 mmol/L; 95% CI -50.61 to -25.61), and there were fewer cases of diarrhoea, RR 0.39; 95% CI 0.20 to 0.76). Non-significant results were obtained for cortisol levels, mean increase in duration of night sleep, mean increase in 24-hour sleep and for number of cases of upper respiratory tract disease and anaemia.Sensitivity analyses were conducted for weight, length and head circumference, and only the finding for length remained significant following removal of studies judged to be at high risk of bias. These three outcomes were the only ones that could also be meta-analysed at follow-up; although both weight and head circumference continued to be significant at 6-month follow-up, these findings were obtained from studies conducted in Eastern countries only. No sensitivity analyses were possible.We conducted 18 meta-analyses measuring aspects of mental health and development. A significant effect favouring the intervention group was found for gross motor skills (SMD -0.44; 95% CI -0.70 to -0.18), fine motor skills (SMD -0.61; 95% CI -0.87 to -0.35), personal and social behaviour (SMD -0.90; 95% CI -1.61 to -0.18) and psychomotor development (SMD -0.35; 95% CI -0.54 to -0.15); although the first three findings were obtained from only two studies, one of which was rated as being at high risk of bias, and the finding for psychomotor development was not maintained following following removal of studies judged to be at high risk of bias in a sensitivity analysis. No significant differences were found for a range of aspects of infant temperament, parent-infant interaction and mental development. Only parent-infant interaction could be meta-analysed at follow-up, and the result was again not significant.

AUTHORS' CONCLUSIONS

These findings do not currently support the use of infant massage with low-risk groups of parents and infants. Available evidence is of poor quality, and many studies do not address the biological plausibility of the outcomes being measured, or the mechanisms by which change might be achieved. Future research should focus on the impact of infant massage in higher-risk groups (for example, demographically and socially deprived parent-infant dyads), where there may be more potential for change.

Use of actigraphy for assessment in pediatric sleep research

The use of actigraphs, or ambulatory devices that estimate sleep-wake patterns from activity levels, has become common in pediatric research. Actigraphy provides a more objective measure than parent-report, and has gained popularity due to its ability to measure sleep-wake patterns for extended periods of time in the child's natural environment. The purpose of this review is: 1) to provide comprehensive information on the historic and current uses of actigraphy in pediatric sleep research; 2) to review how actigraphy has been validated among pediatric populations; and 3) offer recommendations for methodological areas that should be included in all studies that utilize actigraphy, including the definition and scoring of variables commonly reported. The poor specificity to detect wake after sleep onset was consistently noted across devices and age groups, thus raising concerns about what is an "acceptable" level of specificity for actigraphy. Other notable findings from this review include the lack of standard scoring rules or variable definitions. Suggestions for the use and reporting of actigraphy in pediatric research are provided.

Melatonin and mental capacities in newborn infants

OBJECTIVES

To investigate the role of melatonin in the emergence of mental capacities in the newborn infant.

STUDY DESIGN

Assessment of Preterm Infant Behavior examination was performed at 2 weeks post-term age for 39 (21 preterm and 18 term) infants. 6-Suphatoxymelatonin from nocturnal urine samples was analyzed by enzyme-linked immunosorbent assays, and the Mental Developmental Index, assessed by Bayley scales, was correlated at 4, 6, and 9 months' corrected age.

RESULTS

Multivariate analysis of variance with repeated measures showed that improved autonomic function at 2 weeks of age was associated with higher Mental Developmental Index scores at 9 months when related to the amount of melatonin at 4, 6, and 9 months of age.

CONCLUSIONS

Early compromised autonomic system function in preterm infants is associated with lower mental capacities and is related to lower melatonin levels at later ages.

Teaching Chilean mothers to massage their full-term infants: effects on maternal breast-feeding and infant weight gain at age 2 and 4 months

The purpose of this study was to evaluate the effects of massage on infant weight gain and exclusive maternal breast-feeding of an intervention that involved teaching mothers to massage their full-term infants. The sample included 100 healthy newborn infants who were receiving primary healthcare at 3 health centers in a low-income neighborhood of Santiago, Chile. The control group included 65 infants and the massage group included 35 infants. During their second well-child clinic visit, clinic nurses provided instruction to massage-group mothers about how to massage their infants, based on the methods of the Baby's First Massage program (http://www.babysfirstmassage.com/Scripts/default.asp). Mothers were encouraged to massage their infants for 10 to 15 minutes at least once a day, starting when their infants were 15 days old. There was no difference in the mean weights of the infants between the massage and control groups at baseline, but at age 2 months, massage group infants weighed significantly more than control-group infants. There were no weight differences between the 2 groups at age 4 months. There were no differences between the 2 groups on the incidence of exclusive maternal breast-feeding at age 2 or 4 months. The findings suggest that teaching mothers to massage their newborn infants may have a beneficial effect on the infant's early weight gain. There is a need for additional studies to evaluate the effect of maternal massage on other health and welfare outcomes for both mothers and infants.

A neurobiological model for the effects of early brainstem functioning on the development of behavior and emotion regulation in infants: implications for prenatal and perinatal risk

Neurobiological models propose an evolutionary, vertical-integrative perspective on emotion and behavior regulation, which postulates that regulatory functions are processed along three core brain systems: the brainstem, limbic, and cortical systems. To date, few developmental studies applied these models to research on prenatal and perinatal risk. We propose a conceptual model that incorporates three integrated levels of observations for the study of early risk: (a) brainstem-related physiological regulation of cyclic processes and sensory integration, e.g., vagal regulation, circadian rhythms; (b) emotion and attention regulation capacities that draw on the integration of brainstem and limbic systems; and (c) higher-level outcomes that draw on the intactness of brainstem and limbic networks, including socio-emotional self-regulation, inhibitory control, and cognitive processing. We discuss implications of the model for the development of regulatory capacities during the prenatal and early postnatal stages in infants born with specific perinatal risk. We underscore the importance of assessing sub-cortical and brainstem systems and the longitudinal effects of transitory brainstem dysfunction on physiological homeostasis, motivation, arousal-modulated attention, stress reactivity, and mother-infant co-regulation. The assessment of brainstem dysfunction can be conducted during hospitalization and may help detect infants at risk for the development of self-regulatory deficits at the first weeks of life.

Neurobehavioural assessment of skin-to-skin effects on reaction to pain in preterm infants: a randomized, controlled within-subject trial

OBJECTIVE

To assess the immediate and sustained effects of Kangaroo Care on reaction to pain of premature infants.

PATIENTS AND METHODS

A controlled, within-subject randomized study, performed in a large neonatal intensive care unit. Thirty premature infants were observed with blood test stick (BT) or without the blood test stick (W) procedure, either during Kangaroo care (K) or during standard within-crib care (C). Each of the four conditions (BTK, WK, BTC, WC) was observed in four separate sessions: baseline session - 10 min; intervention (BT or W) - 2 min; posttest - 10 min and follow-up - 20 min, in crib (starting 1 h after treatment). For neurobehavioural assessment, the naturalistic observation method was adopted from the Newborn Individualized Developmental Care and Assessment Program (NIDCAP).

RESULTS

During the BTK session (blood test stick with K-care), we observed a decrease in motor disorganization and extension movements and an increase in attention signs, both negative and positive. Significant neurobehavioural changes were sustained in the follow-up period after K-care in comparison to the within-crib-care intervention sessions.

CONCLUSIONS

K-care, as compared to within-crib condition, led to a decrease in stressful neurobehavioural signs after BT procedures in premature infants. Painful procedures such as the BT procedure in premature infants should be performed while the infants are being held in K-care position.

Circadian research in mothers and infants: how many days of actigraphy data are needed to fit cosinor parameters?

Actigraphy is an easily applied approach for assessing activity and circadian patterns in mother-infant dyads. However, timing and duration of actigraphic measurements can affect assessment accuracy. The purpose of this study was to determine the number of days of actigraphy data required to portray circadian rhythm in mothers and their young infants. Continuous actigraphy monitoring was performed in 20 mother-infant pairs over a 4-day period. Cycle mesor, amplitude, acrophase, and R2 were calculated and compared using from 1 to 4 days of data. Parameters based on 4 days of data were correlated with parameters derived from 1 to 3 days of data. There were no differences among mother or infant cosinor parameters except infant acrophase, which stabilized after > or = 2 days of data. Acceptable reliability (r > .80) was achieved with > or = 2 days of data. It was concluded that a recording period of 2 days adequately depicted circadian rhythm of actigraphy in mothers and infants.

Self-hypnosis training for headaches in children and adolescents

OBJECTIVE

To describe the effect of treatment with self-hypnosis for youth with recurrent headaches.

STUDY DESIGN

A retrospective review was conducted of outpatient clinical records of 178 consecutive youths referred to the Behavioral Pediatrics Program (University of Minnesota) from 1988 to 2001 for recurrent headaches. All patients were taught self-hypnosis for self-regulation. Intensity, frequency, and duration of headaches before, during, and after treatment were measured. Outcomes included number and frequency of visits, types of medication, and nature of self-hypnosis practice.

RESULTS

Data were available for 144 patients in this patient self-selected and uncontrolled observation. Compared with self-reports before learning self-hypnosis, children and youths who learned self-hypnosis for recurrent headaches reported reduction in frequency of headache from an average of 4.5 per week to 1.4 per week (P < .01), reduction in intensity (on a self-rating scale of 0 to 12) from an average of 10.3 to 4.7, P < .01, and reduction in average duration from 23.6 hours to 3.0 hours, (P < .01). There were no adverse side effects of self-hypnosis.

CONCLUSIONS

Training in self-hypnosis is associated with significant improvement of chronic recurrent headaches in children and adolescents.

A Model for Caregiving of Adopted Children After Institutionalization

TOPIC

Optimizing caregiving for newly adopted postinstitutionalized children.

PURPOSE

To consider a template of care for postinstitutionalized children based on experiences that physiological measures suggest are expected by infants postbirth.

SOURCES

Published literature and clinical experience.

CONCLUSION

Based on an understanding of physiologically expected care postbirth, special care for postinstitutionalized adopted children might include: close physical contact via use of a sling and cosleeping; breastfeeding or nurturing through food; and responsive caregiving. In replicating earlier missed experiences, parents may assist emotional development in their child and promote attachment development.

Massage intervention for promoting mental and physical health in infants aged under six months

BACKGROUND

Infant massage is increasingly being used in the community for low-risk babies and their primary care givers. Anecdotal claims suggest benefits for sleep, respiration, elimination and the reduction of colic and wind. Infant massage is also thought to reduce infant stress and promote positive parent-infant interaction.

OBJECTIVES

The aim of this review was to assess the effectiveness of infant massage in promoting infant physical and mental health in population samples.

SEARCH STRATEGY

Searches were undertaken of CENTRAL 2005 (Issue 3), MEDLINE (1970 to 2005), PsycINFO (1970 to 2005), CINAHL (1982 to 2005), EMBASE (1980 to 2005), and a number of other Western and Chinese databases.

SELECTION CRITERIA

Studies in which babies under the age of six months were randomised to an infant massage or a no-treatment control group, and utilising a standardised outcome measuring infant mental or physical development.

DATA COLLECTION AND ANALYSIS

Weighted and standardised mean differences and 95% confidence intervals are presented. Where appropriate the results have been combined in a meta-analysis using a random effects model.

MAIN RESULTS

Twenty-three studies were included in the review. One was a follow-up study and thirteen were included in a separate analysis due to concerns about the uniformly significant results and the lack of dropout. The results of nine studies providing primary data suggest that infant massage has no effect on growth, but provides some evidence suggestive of improved mother-infant interaction, sleep and relaxation, reduced crying and a beneficial impact on a number of hormones controlling stress. Results showing a significant impact on number of illnesses and clinic visits were limited to a study of Korean orphanage infants. There was no evidence of effects on cognitive and behavioural outcomes, infant attachment or temperament. The data from the 13 studies regarded to be at high risk of bias show uniformly significant benefits on growth, sleep, crying and bilirubin levels.

AUTHORS' CONCLUSIONS

The only evidence of a significant impact of massage on growth was obtained from a group of studies regarded to be at high risk of bias. There was, however, some evidence of benefits on mother-infant interaction, sleeping and crying, and on hormones influencing stress levels. In the absence of evidence of harm, these findings may be sufficient to support the use of infant massage in the community, particularly in contexts where infant stimulation is poor. Further research is needed, however, before it will be possible to recommend universal provision.

Massage therapy and sleep behaviour in infants born with low birth weight

This study attempts to evaluate the impact of massage therapy on sleep behaviour in infants born with low birth weight (LBW) in St. Petersburg, Russia. Fifty infants (22 boys, 28 girls) who were born in St. Petersburg between 2000 and 2002 and defined as LBW babies (<2500g at birth) were enrolled onto the study at the age of 2 months. Of these, 41 (19 boys, 22 girls) were light and pre-term infants (gestational age < or =36 weeks), and 9 (3 boys, 6 girls) born light at term. The control group consisted of 50 healthy infants born with LBW who were cross-matched with an experimental group of babies and controlled for gender, gestational age, weight and date of birth. The groups were also matched for proximal geographical distribution in the city. Babies in the experimental group were assigned massage intervention therapy that include gentle rubbing, stroking, passive movements of the limbs and other means of kinaesthetic stimulation performed by professionals until the infant is 8 months old. The findings suggest that 8-month-old LBW infants who received massage intervention were less likely to snore during sleep, required less feeding on waking-up at night, and appeared more alert during the day. These apparent correlations remained significant after adjustment was made for major potential confounders. No statistically significant difference was found in sleep behaviour between LBW infants exposed to massage therapy who were either born pre-term or at term. It is suggested that massage may be a valuable approach to improve quality of sleep and reduce sleep-disordered breathing in infants born with LBW. It is acknowledged that whilst this study does not represent a large sample, it is felt that the findings suggest further investigation and offer an insight into an area previously relatively unexplored.

Effects of human contact and vagal regulation on pain reactivity and visual attention in newborns

In two experiments we examined the effects of human contact and vagal regulation on newborns' pain reactivity and visual attention. Baseline cardiac vagal tone was measured during quiet sleep and during the experiment, and vagal withdrawal was indexed as change in vagal tone from baseline to pain (study 1) or attention (study 2). In study 1, 62 healthy newborns were videotaped during a heel-prick procedure and pain reactivity was assessed from micro-level coding of facial expressions, cry behavior, and body movements. Infants were randomly assigned to a contact condition, held by a female assistant, or a no contact condition, on an infant-seat in a similar angle. In study 2, 62 additional healthy newborns, randomly assigned to contact and noncontact conditions, were presented with 2 visual stimuli for a 60 s familiarization period, which were then paired with a novel stimulus. Visual interest, alertness, and novelty preference were coded. Human contact had no effect on the newborns' pain response. Visual attention increased with human contact and newborns in the contact condition looked at the stimuli more frequently, with higher alertness, for longer durations, and had a higher novelty preference. Autonomic reactivity-as indexed by vagal withdrawal-differentiated newborns with intense and mild pain response. Discussion focused on proximity to conspecifics as a contributor to emerging regulatory and adaptive functioning in the human infant.

Ontogenetic development of the mammalian circadian system

This review summarizes the current knowledge about the ontogenetic development of the circadian system in mammals. The developmental changes of overt rhythms are discussed, although the main focus of the review is the underlying neuronal and molecular mechanisms. In addition, the review describes ontogenetic development, not only as a process of morpho-functional maturation. The need of repeated adaptations and readaptations due to changing developmental stage and environmental conditions is also considered. The review analyzes mainly rodent data, obtained from the literature and from the author's own studies. Results from other species, including humans, are presented to demonstrate common features and species-dependent differences. The review first describes the development of the suprachiasmatic nuclei as the central pacemaker system and shows that intrinsic circadian rhythms are already generated in the mammalian fetus. As in adult organisms, the period length is different from 24 h and needs continuous correction by environmental periodicities, or zeitgebers. The investigation of the ontogenetic development of the mechanisms of entrainment reveals that, at prenatal and early postnatal stages, non-photic cues deriving from the mother are effective. Light-dark entrainment develops later. At a certain age, both photic and non-photic zeitgebers may act in parallel, even though the respective time information is 12 h out of phase. That leads to a temporary internal desynchronization. Because rhythmic information needs to be transferred to effector organs, the corresponding neural and humoral signalling pathways are also briefly described. Finally, to be able to transform a rhythmic signal into an overt rhythm, the corresponding effector organs must be functionally mature. As many of these organs are able to generate their own intrinsic rhythms, another aspect of the review is dedicated to the development of peripheral oscillators and mechanisms of their entrainment. The latter includes control by the central pacemaker as well as by distinct environmental signals. Ecological aspects of the described developmental changes in the circadian system and some practical consequences are also briefly discussed.

The nature of touch in mothers experiencing maternity blues: the contribution of parity

BACKGROUND

Maternal touch (MT) is an essential part of the initial contact between the mother and her newborn and has developmental effects on the child. MT is known to be reduced in postpartum depression (PPD). The nature of MT in mothers experiencing maternity blues and the effect of parity are still unknown.

STUDY DESIGN

Seventy-five mothers were recruited from the ongoing series of deliveries.

SUBJECTS

The participating mothers were observed during interaction with their newborns on the second-day postpartum. Touching behavior was scored on-line according to the Touch Scoring Instrument, which includes nine types of MT. Mothers were categorized as exhibiting maternal blues according to Stein's depression scale.

OUTCOME MEASURE

Touch Scoring Instrument.

RESULTS

Primiparous mothers with blues avoided all types of touch whereas multiparous mothers with blues provided firm touch and holding. All mothers with blues avoided proprioceptive touch. Multiparous mothers without maternal blues provided various types of touch including affectionate holding and matter-of-fact touch whereas primiparous mothers without blues mostly provided holding.

CONCLUSIONS

Mothers with maternity blues on day 2 exhibited a pattern of MT similar to that known to characterize postpartum depression. Mothers without blues are able to provide developmental touch in a manner known to facilitate CNS stability and newborn adjustment to the extra-uterine world. Parity modulates the effect of maternity blues on MT and buffers the withdrawal effect of depression. Maternal touch could be used as a diagnostic tool for detection of mothers at risk in a timely manner. Touch interventions, which were previously demonstrated in PPD mothers, may be utilized in an earlier stage postpartum.

The effect of skin-to-skin contact (kangaroo care) shortly after birth on the neurobehavioral responses of the term newborn: a randomized, controlled trial

BACKGROUND

The method of skin-to-skin contact (kangaroo care [KC]) has shown physiologic, cognitive, and emotional gains for preterm infants; however, KC has not been studied adequately in term newborns.

AIMS

To evaluate the effect of KC, used shortly after delivery, on the neurobehavioral responses of the healthy newborn.

STUDY DESIGN

A randomized, controlled trial using a table of random numbers. After consent, the mothers were assigned to 1 of 2 groups: KC shortly after delivery or a no-treatment standard care (control group).

SUBJECTS

Included were 47 healthy mother-infant pairs. KC began at 15 to 20 minutes after delivery and lasted for 1 hour. Control infants and KC infants were brought to the nursery 15 to 20 and 75 to 80 minutes after birth, respectively.

RESULTS

During a 1-hour-long observation, starting at 4 hours postnatally, the KC infants slept longer, were mostly in a quiet sleep state, exhibited more flexor movements and postures, and showed less extensor movements.

CONCLUSIONS

KC seems to influence state organization and motor system modulation of the newborn infant shortly after delivery. The significance of our findings for supportive transition from the womb to the extrauterine environment is discussed. Medical and nursing staff may be well advised to provide this kind of care shortly after birth.

Emotion regulation and touch in infants: the role of cholecystokinin and opioids

Behavioral-pharmacological research in infant rats supports the role of cholecystokinin (CCK) and opioid peptides in mediating early learning of new associations with aspects of the nest and dam, such as maternal odor, milk, and contact. The current paper reviews research that examines the hypothesis that these neuropeptide systems are further involved in mediating emotion regulation in infants, thus playing a role in the emergence of stress-reactivity and other motivational systems. The beneficial effects of maternal proximity, handling, and touch on the development of emotion regulation have been demonstrated in both human and animal models. Interventions that promote tactile stimulation of the infant ("touch therapy") and infant-mother contact ("skin-to-skin contact" or "kangaroo care") have been shown to improve the infant's ability to self-regulate, and to moderate the effects of some risk factors. Theoretical perspectives and empirical findings regarding emotion regulation in infants are first discussed. This is followed by a review of work providing evidence in animal models (and suggestive evidence in humans) for the importance of CCK and opioid neuropeptides in affecting infant emotion regulation and the impact of touch-based interventions, in particular in the context of infant-mother attraction, contact, separation, and attachment.
