Late weaning and maternal closeness, associated with advanced motor and visual maturation, reinforce autonomy in healthy, 2-year-old children

Concept analysis of maternal-infant attachment during the weaning process

BACKGROUND

At the time that the mother and baby transit from breastfeeding to weaning, maternal-fetal attachment becomes a crucial basis for maintaining their emotional relationship. Conceptualization is needed to better understand the phenomenon of maternal-infant attachment during the weaning process.

OBJECTIVE

The purpose of this paper is to explore and identify the essence of the term maternal-infant attachment during weaning and to arrive at an operational definition of the concept.

METHOD

Concept analysis following Walker and Avant.

RESULTS

The attributes of maternal-infant attachment during the weaning process include (1) consistent and properly timed, (2) dynamic transactional interaction, and (3) secured adjustment. Maternal-infant attachment during the weaning process is brought by maternal sensitivity, closeness and proximity seeking, gentle and positive weaning, and breastfeeding experiences, which later turn into favorable emotion regulation, maturity, self-efficacy, secured bond, less intrusive interaction, resilience, and child's behavioral and development.

CONCLUSION

This concept analysis provides new insight into maternal-infant attachment during the weaning process that guides the nursing practice. Also, the findings can help develop or improve the models, theories, and instruments collected for maintaining maternal-fetal attachment during the weaning process.

Nurse-Driven Interventions for Improving ELBW Neurodevelopmental Outcomes

Survival rates for extremely low-birth-weight (ELBW) infants are improving as neurodevelopmental impairment (NDI) rates stay stable, thereby increasing the overall number of infants with NDI. Although there are many determinants of NDI in this population, nutritional factors are of interest because they are readily modifiable in the clinical setting. Nurses can influence nutritional factors such as improving access to human milk feeding, using growth monitoring, establishing feeding policies, implementing oral care with colostrum, facilitating kangaroo care, and providing lactation education for the mother. All of these measures assist in leading to a decrease in NDI rates among ELBW infants.

Association between fetal abdominal growth trajectories, maternal metabolite signatures early in pregnancy, and childhood growth and adiposity: prospective observational multinational INTERBIO-21st fetal study

BACKGROUND

Obesity predominantly affects populations in high-income countries and those countries facing epidemiological transition. The risk of childhood obesity is increased among infants who had overweight or obesity at birth, but in low-resource settings one in five infants are born small for gestational age. We aimed to study the relationships between: (1) maternal metabolite signatures; (2) fetal abdominal growth; and (3) postnatal growth, adiposity, and neurodevelopment.

METHODS

In the prospective, multinational, observational INTERBIO-21st fetal study, conducted in maternity units in Pelotas (Brazil), Nairobi (Kenya), Karachi (Pakistan), Soweto (South Africa), Mae Sot (Thailand), and Oxford (UK), we enrolled women (≥18 years, with a BMI of less than 35 kg/m², natural conception, and a singleton pregnancy) who initiated antenatal care before 14 weeks' gestation. Ultrasound scans were performed every 5±1 weeks until delivery to measure fetal growth and feto-placental blood flow, and we used finite mixture models to derive growth trajectories of abdominal circumference. The infants' health, growth, and development were monitored from birth to age 2 years. Early pregnancy maternal blood and umbilical cord venous blood samples were collected for untargeted metabolomic analysis.

FINDINGS

From Feb 8, 2012, to Nov 30, 2019, we enrolled 3598 pregnant women and followed up their infants to 2 years of age. We identified four ultrasound-derived trajectories of fetal abdominal circumference growth that accelerated or decelerated within a crucial 20-25 week gestational age window: faltering growth, early accelerating growth, late accelerating growth, and median growth tracking. These distinct phenotypes had matching feto-placental blood flow patterns throughout pregnancy, and different growth, adiposity, vision, and neurodevelopment outcomes in early childhood. There were 709 maternal metabolites with positive effect for the faltering growth phenotype and 54 for the early accelerating growth phenotype; 31 maternal metabolites had a negative effect for the faltering growth phenotype and 76 for the early accelerating growth phenotype. Metabolites associated with the faltering growth phenotype had statistically significant odds ratios close to 1·5 (ie, suggesting upregulation of metabolic pathways of impaired fetal growth). The metabolites had a reciprocal relationship with the early accelerating growth phenotype, with statistically significant odds ratios close to 0.6 (ie, suggesting downregulation of fetal growth acceleration). The maternal metabolite signatures included 5-hydroxy-eicosatetraenoic acid, and 11 phosphatidylcholines linked to oxylipin or saturated fatty acid sidechains. The fungicide, chlorothalonil, was highly abundant in the early accelerating growth phenotype group.

INTERPRETATION

Early pregnancy lipid biology associated with fetal abdominal growth trajectories is an indicator of patterns of growth, adiposity, vision, and neurodevelopment up to the age of 2 years. Our findings could contribute to the earlier identification of infants at risk of obesity.

Promoting the practice of exclusive breastfeeding: a philosophic scoping review

Background

The World Health Organization recommends exclusive breastfeeding for the first 6 months of an infant’s life and continued breastfeeding for 2 years. The global rate of exclusive breastfeeding is low at 33%. Thus, it is important to identify philosophical and theory-based strategies that can promote exclusive breastfeeding. The aim of the study was to identify philosophical schools of thought and theories used in research on promoting the practice of exclusive breastfeeding.

Methods

A scoping review using Arksey and O'Malley's framework explored the phenomenon of exclusive breastfeeding practice promotion. Searches were conducted using CINAHL Plus full-text, PubMed, APA PsycInfo, and Academic Search Premier. Search terms included theory, philosophy, framework, model, exclusive breastfeeding, promotion, support, English, and publication between 2001—2022.

Results

The online search yielded 1,682 articles, however, only 44 met the inclusion criteria for the scoping review. The articles promoting exclusive breastfeeding used pragmatism (n = 1) or phenomenology (n = 2) philosophies and theories of self-efficacy (n = 10), theory of planned behaviour (n = 13), social cognitive theories (n = 18) and represented 16 countries. Theories of self-efficacy and planned behaviour were the most used theories.

Conclusions

This review suggests that theories and models are increasingly being used to promote exclusive breastfeeding. Orienting exclusive breastfeeding programmes within theoretical frameworks is a step in the right direction because theories can sensitize researchers and practitioners to contextually relevant factors and processes appropriate for effective exclusive breastfeeding strategies. Future research should examine the efficacy and effectiveness of theory-informed exclusive breastfeeding programmes over time. Such information is important for designing cost-effective EBF programmes.

Complex Perinatal Syndromes Affecting Early Human Growth and Development: Issues to Consider to Understand Their Aetiology and Postnatal Effects

Complex perinatal syndromes (CPS) affecting pregnancy and childhood, such as preterm birth, and intra- and extra-uterine growth restriction, have multiple, diverse contexts of complexity and interaction that determine the short- and long-term growth, health and development of all human beings. Early in life, genetically-guided somatic and cerebral development occurs alongside a psychism "in statu nascendi," with the neural structures subjected to the effects of the intra- and extra-uterine environments in preparation for optimal postnatal functioning. Different trajectories of fetal cranial and abdominal growth have been identified before 25 weeks' gestation, tracking differential growth and neurodevelopment at 2 years of age. Similarly, critical time-windows exist in the first 5-8 months of postnatal life because of interactions between the newborn and their environment, mother/care-givers and feeding practices. Understanding these complex relational processes requires abandoning classical, linear and mechanistic interpretations that are placed in rigid, artificial biological silos. Instead, we need to conduct longitudinal, interdisciplinary research and integrate the resulting new knowledge into clinical practice. An ecological-systemic approach is required to understand early human growth and development, based on a dynamic multidimensional process from the molecular or genomic level to the socio-economic-environmental context. For this, we need theoretical and methodological tools that permit a global understanding of CPS, delineating temporal trajectories and their conditioning factors, updated by the incorporation of new scientific discoveries. The potential to optimize human growth and development across chronological age and geographical locations - by implementing interventions or "treatments" during periods of greatest instability or vulnerability - should be recognized. Hence, it is imperative to take a holistic view of reproductive and perinatal issues, acknowledging at all levels the complexity and interactions of CPS and their sensitive periods, laying the foundations for further improvements in growth and development of populations, to maximize global human potential. We discuss here conceptual issues that should be considered for the development and implementation of such a strategy aimed at addressing the perinatal health problems of the new millenium.

Factors Associated with Delayed Initiation and Cessation of Breastfeeding Among Working Mothers in Abu Dhabi, the United Arab Emirates

INTRODUCTION

Despite the enormous benefits of breastfeeding, working mothers face more challenges to meet the World Health Organization (WHO) recommendations regarding successful breastfeeding practices. Little research has been done to understand the breastfeeding practices among working mothers in the United Arab Emirates (UAE). Thus, the aim of this study was to investigate the prevalence and factors associated with delayed initiation and cessation of breastfeeding among working mothers with children under the age of two years in Abu Dhabi, the UAE.

METHODS

A cross-sectional multicenter study was conducted from March to September 2017. The study included both Emirati and non-Emirati mothers of children below the age of two years. The data were collected from seven government health care centers in Abu Dhabi as well as from the community. Mothers with young children attending the centers during the study days were approached by trained research assistants, who provided oral and written information about the study.

RESULTS

Among the 1610 mother-child pairs with complete data who were included in this study, 606 were working mothers giving an employment rate of 37.6%. The mean (standard deviation) of maternal age and children's age were 30.9 (5.1) years and 8.6 (6.1) months, respectively. Of the 606 mothers, 217 (35.8%) delayed initiation of breastfeeding, and 359 (59.2%) ceased breastfeeding. In multivariable logistic regression analysis, factors associated with delayed breastfeeding initiation among working mothers were older mother age (adjusted odds ratio [AOR] 1.04, 95% confidence interval [CI]1.01, 1.08), being of non-Arab nationality (AOR 2.24, 95% CI 1.53, 3.27), caesarean section (AOR 2.70, 95% CI 1.84, 3.96), non-rooming-in (AOR 3.85, 95% CI 1.56, 9.51) and mothers with low birth weight children (AOR 2.47, 95% CI 1.23, 4.94). The main factors associated with cessation of breastfeeding were being of non-Arab nationality (AOR 1.59, 95% CI 1.09, 2.31) and mother with high-income rating (AOR 2.79, 95% CI 1.36, 5.75).

CONCLUSION

The study highlighted the need for urgent actions to improve the working mothers' conditions in order to promote optimal breastfeeding practices, including both early initiation and continuation of breastfeeding among all mothers in the UAE regardless of employment status. Policies to improve EBF rates among professional working mothers should include maternity leave extension to enable mothers to continue breastfeeding.
