Improving mother-infant interaction during infant feeding: A randomised controlled trial in a low-income community in South Africa

Home-visiting Parenting Programs to Improve Mother-Infant Interactions at Early Ages: A Systematic Review

Objective: To systematically review studies examining the effects of home-visiting preventive parenting programs (HV-PPs) on improving the quality of mother-child interactions in early childhood. Method: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol, we identified 3,586 studies published between 2018 and 2022 by searching the following databases: PubMed, Web of Science, BVS/LILACS, SciELO, and PsycNET/PsycINFO. After applying the eligibility criteria, 17 articles were selected for review. Results: Most studies were conducted in high-income countries (53%) and the remainder were conducted in upper-middle-income countries, predominantly using a randomized controlled trial design and with strong methodological quality. The 17 studies applied 13 different HV-PPs, predominantly using video feedback, based on various dosages and schedules. Most studies (77%) showed significant positive effects on mother-child interactions by improving mainly positive maternal behaviors (e.g., sensitivity and responsiveness). Positive effects occurred independent of the study design, sample characteristics, measures, and constructs assessed. However, the findings suggest that the combination of fewer than six sessions, durations shorter than three months, and a very early start did not impact mother-child interactions, as expected. Few studies have explored negative maternal behaviors, children's behaviors, and dyadic interactions such as mutuality and synchrony. Conclusions: HV-PPs positively impacted mother-child interactions in early childhood despite the large heterogeneity across program designs, outcome measures, and overlapping constructs. Based on the results, we discuss the practical and economic implications of using parenting programs as a preventive approach.

Evaluating caregiver-child interactions in low- and middle-income countries: a systematic review of tools and methods

AIMS/BACKGROUND

The United Nations Sustainable Development Goals (SDGs) has placed emphasis on improving early child development globally. This is supported through the Nurturing Care Framework which includes responsive caregiving. To evaluate responsive caregiving, tools to assess quality of caregiver-child interactions are used, however there is little information on how they are currently employed and/or adapted particularly in low- and middle-income countries (LMICs) where children have a greater risk of adverse outcomes. The aim of this review is to provide a comprehensive guide on methodologies used to evaluate caregiver-child interaction - including their feasibility and cultural adaptation.

DESIGN/METHODS

We conducted a systematic review of studies over 20years in LMICs which assessed caregiver-child interactions. Characteristics of each tool, their validity (assessed with COSMIN Risk of Bias checklist), and the quality of the study (Mixed Methods Appraisal Tool) are reported.

RESULTS

We identified 59 studies using 34 tools across 20 different LMICs. Most tools (86.5%) employed video-recorded observations of caregiver-child interactions at home (e.g. Ainsworth's Sensitivity Scale, OMI) or in the laboratory (e.g. PICCOLO) with a few conducting direct observations in the field (e.g. OMCI, HOME); 13.5% were self-reported. Tools varied in methodology with limited or no mention of validity and reliability. Most tools are developed in Western countries and have not been culturally validated for use in LMIC settings.

CONCLUSION

There are limited caregiver-child interaction measures used in LMIC settings, with only some locally validated locally. Future studies should aim to ensure better validity, applicability and feasibility of caregiver-child interaction tools for global settings.

The trajectories of physical growth in 4 months postnatal corrected age among preterm infants discharged from neonatal intensive care units and associated factors: A prospective study

Objectives

Growth retardation is a risk for premature infants. In addition to demographic and perinatal factors, preterm infants' physical growth may be affected by neonatal intensive care unit (NICU) stress, maternal postpartum depression, and mother-infant interaction. This study aimed to investigate the trajectories of physical growth in 4 months corrected age among preterm infants discharged from the NICU and the impactors on these trajectories.

Methods

A prospective study was conducted among 318 preterm infants from September 2019 to April 2021 in Shanghai, China. Latent growth modeling was applied to identify the weight, length, and head circumference growth trajectories in 4 months corrected age and explore the effects of demographic and medical characteristics, infant stress during NICU stay, maternal postpartum depression, and mother-infant interaction on each trajectory.

Results

Unconditional latent growth models showed curve trajectories with increasingly slower growth in weight, length, and head circumference until 4 months of corrected age. Conditional latent growth models showed that a longer length of stay in the NICU and more skin punctures were negatively associated with weight at 40 weeks corrected gestational age (β = -0.43 and -0.19, respectively, P < 0.05). The maternal postpartum depression between 40 weeks corrected gestational age and 1 month corrected postnatal age was associated with a lower growth rate of length (β = -0.17, P = 0.040), while between 2 and 3 months corrected postnatal age, there were lower growth rates of weight and head circumference (β = -0.15 and -0.19, respectively, P < 0.05). The mother-infant interaction scores between 40 weeks corrected gestational age and 1 month corrected postnatal age negatively predicted the growth rate of weight (β = -0.19, P = 0.020).

Conclusion

The physical growth trajectories of preterm infants discharged from the NICU were influenced by infant stress during the NICU stay, maternal postpartum depression and mother-infant interaction.

Behaviour change interventions improve maternal and child nutrition in sub-Saharan Africa: A systematic review

Evidence that nutrition-specific and nutrition-sensitive interventions can improve maternal and child nutrition status in sub-Saharan Africa is inconclusive. Using behaviour change theory and techniques in intervention design may increase effectiveness and make outcomes more predictable. This systematic review aimed to determine whether interventions that included behaviour change functions were effective. Six databases were searched systematically, using MeSH and free-text terms, for articles describing nutrition-specific and nutrition-sensitive behaviour change interventions published in English until January 2022. Titles, abstracts and full-text papers were double-screened. Data extraction and quality assessments followed Centre for Reviews and Dissemination guidelines. Behaviour change functions of interventions were mapped onto the COM-B model and Behaviour Change Wheel. PROSPERO registered (135054). The search yielded 1193 articles: 79 articles met inclusion criteria, ranging from low (n = 30) to high (n = 11) risk of bias. Many that applied behaviour change theory, communication or counselling resulted in significant improvements in infant stunting and wasting, household dietary intake and maternal psychosocial measures. Interventions with >2 behaviour change functions (including persuasion, incentivisation, environmental restructuring) were the most effective. We recommend incorporating behaviour change functions in nutrition interventions to improve maternal and child outcomes, specifically drawing on the Behaviour Change Wheel, COM-B model (SORT B recommendation). To enhance the designs of these interventions, and ultimately improve the nutritional and psychosocial outcomes for mothers and infants in sub-Saharan Africa, collaborations are recommended between behaviour change and nutrition experts, intervention designers, policy makers and commissioners to fund and roll-out multicomponent behaviour change interventions.

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.

Measurement tools and indicators for assessing nurturing care for early childhood development: A scoping review

Nurturing care encompasses five components that are crucial for supporting early childhood development: good health, adequate nutrition, opportunities for early learning, responsive caregiving, and safety and security. While there has been increasing attention in global public health towards designing and delivering programs, services, and policies to promote nurturing care, measurement has focused more on the components of health and nutrition, with less attention to early learning, responsive caregiving, and safety and security. We conducted a scoping review to identify articles that measured at least one nurturing care outcome in a sample of caregivers and/or children under-5 years of age in low- and middle-income countries (LMICs). We systematically searched five electronic bibliographic databases for peer-reviewed articles published from database inception until November 30, 2020. We first classified outcomes to their respective nurturing care component, and then applied an inductive approach to organize key constructs within each nurturing care component and the specific measures and indicators used across studies. We identified 239 total articles representing more than 50 LMICs for inclusion in the review. The majority of included studies reported a measure of nutrition (N = 166), early learning (N = 140), and health (N = 102), followed by responsive caregiving (N = 78) and lastly safety and security (N = 45). For each nurturing care component, we uncovered multiple constructs relevant to children under-5: nutrition (e.g., anthropometry, complementary feeding), early learning (e.g., stimulation practices, early childhood education), health (e.g., birth outcomes, morbidity), responsive caregiving (e.g., parental responsivity, parent-child interactions), and safety and security (e.g., discipline, inadequate supervision). Particularly for outcomes of early learning and responsive caregiving, there was greater variability with regards to the measures used, reported indicators, and analytic construction of variables than the other three nurturing care components. This study provides a comprehensive review of the current state of measurement of nurturing care. Additional research is needed in order to establish the most optimal measures and indicators for assessing nurturing care, especially for early learning and responsive caregiving.
