Group-based parenting interventions to promote child development in rural Kenya: a multi-arm, cluster-randomised community effectiveness trial

Autonomy and risk perception in Congo Basin developmental systems

This paper explores how cultural learning dynamics shape children's encounters with risk and, through developmental feedbacks, lead to stability or change in community-level risk perception and adaptation. I draw on cultural evolutionary theory to describe trade-offs communities face in shaping how children perceive and encounter risks: between social learning and individual learning; learning via teaching versus situated and collaborative learning; and inter- versus intra-generational social learning. After reviewing theoretical implications of these trade-offs, I examine how they manifest in intensive parenting in the Global North, which emphasizes teaching and vertical transmission (from parents) in children's learning about risk. This case study illustrates the potential for cultural evolution of maladaptive perceptions of risk in the face of environmental change. Then, I use the trade-off framework to analyze time allocation data from children (ages 4-16 years) from two small-scale societies in the Central African Republic, the Aka and the Ngandu. I show that Aka and Ngandu children spend more time with other children than with adults. Bayesian regression modeling further shows that adult availability decreases the probability children engage in risky activities, including work, which is consistent with respect for children's autonomy and an age-graded division of labor. Yet, when adults are available, risky work-but not play or other activities-increases probability of adult intervention, typically to guide children's work, not to avoid risks. Using these case studies, I discuss how autonomy is critical to balancing trade-offs inherent to conservative and rigid culture learning in contexts of local environmental change.

Understanding Stunting: Impact, Causes, and Strategy to Accelerate Stunting Reduction-A Narrative Review

Stunting is a major global health concern, particularly in low- and middle-income countries, due to its persistently high prevalence. It often originates from chronic malnutrition during the critical first 1000 days of life. Maternal and child nutrition are critical determinants of a child's growth and development. This article aimed to explore the impact, causes, and evidence-based strategies to accelerate the reduction of stunting incidence worldwide. This review was undertaken with sources from PubMed, Scopus, Google Scholar, Science Direct, and MEDLINE from October 2024 to January 2025. This review was undertaken with sources from PubMed, Scopus, Google Scholar, Science Direct, and MEDLINE from October 2024 to January 2025 using the keyword "Stunting", "Causes of stunting", "Stunting Impact", "Stunting Intervention", and "Stunting Prevention". The findings highlight the multifactorial causes of stunting, including maternal malnutrition, inadequate breastfeeding and complementary feeding, poor sanitation, and socioeconomic factors. Stunting is associated with impaired linear growth, cognitive deficits, gut dysbiosis, endocrine disruption, anemia, and increased risk of chronic diseases later in life. Addressing stunting demands multisectoral strategies focusing on maternal and child nutrition, infection prevention, improved WASH (Water, Sanitation, and Hygiene) practices, and socioeconomic support. The evidence presented may guide policy development and targeted interventions to prevent stunting and its long-term effects.

Nurturing care in the first 10 years of life: Results from a Vietnamese longitudinal study

Nurturing care (NC) is essential for children to meet their optimal development potential. However, the various NC dimensions and their patterns from preconception through adolescence have not been comprehensively documented. This study explored five NC dimensions (health, nutrition, safety/security, learning, and relationships) using prospectively collected data from 1040 mother-child dyads in a birth cohort conducted in Vietnam from 2011 to 2023. We described distributions of age-specific variables of the NC dimensions from preconception through ages 2, 6, and 10 years, and generated scaled scores that ranged from 0 to 1. Mean scores varied across dimensions and life stages (range: 0.45-0.83). The scores were 0.1-0.2 points higher among mothers with higher schooling levels. Smaller differences (0.03-0.06 points) in scores were also observed between ethnicities, but no significant difference was observed between boys and girls. We observed positive correlations among most of the five dimensions within each study period (r range: 0.03-0.38). The variation of NC dimensions across different time points indicates a need to measure NC across life stages. Our findings demonstrate important gaps in gaining full achievement in NC from preconception through age 10 years.

A community-based intervention (the Omama Project) improves neurodevelopment in impoverished 2-year-old Roma children: a quasi-experimental observational study

High rates of childhood neurodisability are reported among the Roma, Europe's largest ethnic minority community. Interventions targeting early child development (ECD) during the first 2 years of life can improve neurodevelopmental outcomes in vulnerable children; however, evidence from Roma preschoolers is scarce. In a quasi-experimental observational study, we compared neurodevelopmental outcomes at age 2 years, measured on the INTERGROWTH-21st Project Neurodevelopmental Assessment (INTER-NDA), between Roma children receiving a community-based ECD intervention (RI, n = 98), and age- and sex-matched Roma and non-Roma children (RC, n = 99 and NRC, n = 54, respectively) who did not receive the intervention in Eastern Slovakia. The intervention was delivered between 3 weeks and 20 months in weekly home-based sessions by trained Roma women from matched settlements to RIs. Compared with RC, RI had higher 2-year cognitive (B = 0.15; 95% CI, 0.04, 0.25), language (B = 0.25; 95% CI, 0.11, 0.38) and fine motor (B = 0.08; 95% CI, 0.01, 0.16) scores. After adjustment for covariates, cognitive delay decreased by 88% in RI compared with RC (aOR, 0.12; 95% CI, 0.03, 0.53). Linear growth at 24 months was a key predictor of developmental scores for both groups (range, B = 0.04-0.14; 95% CI, 0.01, 0.07 and 0.09, 0.20).

CONCLUSIONS

Our results highlight that, without directly intervening on nutritional and poverty status, a community-based ECD intervention, delivered by trained Roma women to Roma children, can significantly improve neurodevelopmental outcomes at age 2 years.

WHAT IS KNOWN

• The Roma are Europe's largest ethnic minority. High rates of neurodisability, malnutrition and poverty are reported in Roma preschoolers. • Optimal early child development (ECD) is foundational to lifecourse health and wellbeing. Early interventions improve ECD outcomes in vulnerable children; however, evidence from Roma communities is limited.

WHAT IS NEW

• The Omama project is a community-based ECD intervention, delivered by trained Roma women to Roma children aged 3 weeks to 20 months living in impoverished settlements in Eastern Slovakia. • Roma children receiving the intervention had (i) higher cognitive, language and fine motor scores and (ii) lower rates of cognitive delay compared with controls.

Engaging fathers(to-be): a pilot study on the adaptation and programme experience of SMS4baba intervention in Kenya's informal settlements

BACKGROUND

Engaging fathers(to-be) can improve maternal, newborn, and child health outcomes. However, father-focused interventions in low-resource settings are under-researched. As part of an integrated early childhood development pilot cluster randomised trial in Nairobi's informal settlements, this study aimed to test the feasibility of a text-only intervention for fathers (SMS4baba) adapted from one developed in Australia (SMS4dads).

METHODS

A multi-phased mixed-methods study, which included an exploratory qualitative phase and pre-post evaluation of the adapted SMS4baba text-only intervention was conducted between 2019 and 2022. Three focus-group discussions (FGDs) with 19 fathers were conducted at inception to inform SMS4baba content development; two post-pilot FGDs with 12 fathers explored the acceptability and feasibility of SMS4baba implementation; and 4 post-intervention FGDs with 22 fathers evaluated SMS4baba programme experiences. In the intervention phase, 72 fathers were recruited to receive SMS4baba messages thrice weekly from late pregnancy until over six months postpartum. A pre-enrolment questionnaire captured fathers' socio-demographic characteristics. Pre-post surveys were administered telephonically, and outcome measures evaluated using a paternal antenatal attachment scale, generalised anxiety disorder scale (GAD-7), patient health questionnaire (PHQ-9), and researcher-developed questionnaire items assessing paternal involvement, childcare and parenting practices. Qualitative data were analysed using a thematic approach. Statistical analysis performed included descriptive statistics, tests of association, and mixed model regression to evaluate outcomes.

RESULTS

Fathers perceived SMS4baba messages as educational, instilling new knowledge and reinforcing positive parenting, and helped fathers cope with fatherhood transition. High levels of engagement by reading and sharing the texts was reported, and fathers expressed strong approval of the SMS4baba messages. SMS4baba's acceptability was attributed to modest message frequency and utilising familiar language. Fathers reported examples of behaviour change in their parenting and spousal support, which challenged gendered parenting norms. Pre-post measures showed increased father involvement in childcare (Cohen's d = 2.17, 95%CI [1.7, 2.62]), infant/child attachment (Cohen's d = 0.33, 95%CI [-0.03, 0.69]), and partner support (Cohen's d = 0.5, 95%CI [0.13, 0.87]).

CONCLUSION

Our findings provide support for father-specific interventions utilising digital technologies to reach and engage fathers from low-resource settings such as urban informal settlements. Exploration of text messaging channels targeting fathers, to address family wellbeing in the perinatal period is warranted.

Integrated child nutrition, parenting, and health intervention in rural Liberia: A mixed-methods feasibility study

In Liberia, children are exposed to multiple forms of adversity which can negatively impact their health and development. Research is needed to examine the feasibility and benefits of integrated interventions that can be incorporated into existing health delivery programs to simultaneously address low responsive stimulation, undernutrition, and infection. This study assessed the feasibility of an integrated intervention promoting psychosocial stimulation and improved child feeding by the provision of eggs and fish. The integrated intervention was incorporated into an existing government health program. Thirty female caregiver-child dyads were randomly selected from two rural communities in Liberia. Participants received fortnightly group parenting sessions and weekly eggs and fish designated for child consumption, for four weeks. Trained community health workers delivered the intervention. Assessments were conducted before and after the intervention using quantitative surveys and qualitative interviews. At baseline, we examined the home environment, caregiver-child interactions, diet, and infection control practices. At endline, we assessed the feasibility of the intervention. Descriptive analyses were conducted with quantitative data. Qualitative data were analyzed using conventional content analysis. Baseline findings indicated uncommon responsive parenting, inadequate early learning opportunities, high food insecurity, and high child morbidity. Mixed methods indicators of feasibility, including acceptability, adoption, and fidelity were high. Qualitative data from this feasibility study informed several future modifications to the program, including engaging fathers, supplementing group sessions with home visits, and broadening facilitator eligibility. This integrated intervention is feasible and can be incorporated into existing health programs to support early child development.

Caregiving experiences and practices: qualitative formative research towards development of integrated early childhood development interventions targeting Kenyans and refugees in Nairobi's informal settlements

BACKGROUND

Evidence is needed to understand factors that influence child development and caregiving experiences, especially in marginalized contexts, to inform the development and implementation of early childhood development (ECD) interventions. This study explores caregiving practices for young children in an urban informal settlement with Kenyans and embedded refugees, and identifies factors shaping these caregiving experiences, to inform the design and development of potentially appropriate ECD interventions.

METHODS

A qualitative formative study, which included 14 focus group discussions (n = 125 participants), and 13 key informant interviews was conducted between August and October 2018. Purposive sampling approaches were used to select a diverse range of respondents including caregivers of children below three years of age and stakeholders of Kenyan nationality and refugees. Data were analysed using a thematic approach and the Nurturing Care Framework was used as an interpretative lens.

RESULTS

There was a fusion of traditional, religious and modern practices in the care for young children, influenced by the caregivers' culture, and financial disposition. There were mixed views/practices on nutrition for young children. For example, while there was recognition of the value for breastfeeding, working mothers, especially in the informal economy, found it a difficult practice. Stimulation through play was common, especially for older children, but gaps were identified in aspects such as reading, and storytelling in the home environment. Some barriers identified included the limited availability of a caregiver, insecurity, and confined space in the informal settlement, all of which made it difficult for children to engage in play activities. Physical and psychological forms of discipline were commonly mentioned, although few caregivers practiced and recognized the need for using non-violent approaches. Some overarching challenges for caregivers were unemployment or unstable sources of income, and, particularly for refugee caregivers, their legal status.

CONCLUSION

These findings point to the interplay of various factors affecting optimal caregiving for young children in an urban informal settlement with Kenyans and refugees. Integrated ECD interventions are needed for such a mixed population, especially those that strive to anchor along caregivers' social support system, co-designed together with community stakeholders, that ideally focus on parent skills training promoting nurturing care and economic empowerment.

Integrating early child development into an existing health and nutrition program: evidence from a cluster-randomized controlled trial

INTRODUCTION

In low-resource settings, introducing child health programs into community services may compete for caregiver time. We analyzed the impact of a new early childhood development (ECD) program in rural Madagascar on family attendance at other health services and of adding at-home play materials on program attendance.

METHODS

We randomized 75 communities where community health workers (CHWs) implement an existing child health and nutrition program (Projet d'Amélioration des Résultats Nutritionnels or PARN), the status quo. We offered two 6-month cycles of 12 ECD sessions to eligible caregiver-child dyads (6-30 months) in 25 sites [T]; we added take-home play materials in Cycle 2 to 25 sites [T+]. We used differences-in-differences with administrative data to analyze the effect of offering ECD sessions on monthly PARN attendance (T+/T vs. C) among age-eligible children and the impact of toy boxes/libraries on monthly ECD session attendance (T + vs. T). We used random intercept models to analyze characteristics associated with program registration.

RESULTS

We analyzed data for 9,408 dyads; 30% and 32% registered for the program in Cycle 1 and 2 (respectively). On average, CHWs delivered 11.4 sessions (SD: 1.5). Children from wealthier households who already attended PARN sessions were more likely to register, and we found no effect of T or T + on PARN attendance. Adding play materials did not affect monthly ECD session attendance. Children from more populated sites were less likely to participate in both ECD and PARN sessions.

CONCLUSIONS

Integrating new services for ECD into the health system was feasible and did not reduce dyad participation in existing services. Investment in health services in more populated areas is needed to provide coverage to all eligible children. Novel strategies should be explored to engage the most vulnerable children in new and existing health services.

A parenting program delivered through existing community-based peer groups to improve early child development in Homabay and Busia Counties, Kenya: study protocol for a cluster-randomized controlled trial

BACKGROUND

Poor early childhood development (ECD) is a major global health concern that is associated with various adverse outcomes over the lifecourse. Parenting interventions especially during the earliest years of life can benefit ECD. However, there is limited evidence from Kenya about the effectiveness of parenting interventions for improving ECD outcomes especially across rural disadvantaged communities. This paper describes the study protocol for an impact and implementation evaluation of a community-based group parenting program that aims to improve ECD in rural Kenya.

METHODS

We will conduct a cluster-randomized controlled trial to determine the effectiveness of a parenting program for caregivers of young children in Homabay and Busia counties in Western Kenya. Sixty-four village clusters will be randomly assigned to either the parenting intervention arm or the waitlist control arm with stratification by county. In each village, 10 primary caregivers with a child aged 0-24 months will be enrolled. The parenting program will be delivered through existing peer groups within communities whereby caregivers will receive counseling and psychosocial support to enhance their parenting skills and wellbeing to in turn promote ECD. The intervention curriculum comprises 21 sessions targeting various nurturing care messages, including early learning, responsive caregiving, child nutrition, health, protection, and caregiver mental health. Group sessions are facilitated by a trained volunteer biweekly for a total of 11 months. The primary trial outcome is an overall measure of ECD using the Global Scales of Early Development long form version. Secondary outcomes include various caregiver outcomes (e.g., parenting practices, mental health) and other child outcomes (e.g., socioemotional development, dietary diversity). All outcomes will be assessed at baseline and endline. We will also conduct a qualitative implementation evaluation at endline and interview various stakeholders to assess program fidelity, quality, and sustainability.

DISCUSSION

This trial will evaluate the effectiveness of a parenting intervention on ECD and caregiving outcomes and assess program implementation quality as delivered through existing community-based peer groups. This study will provide rigorous evidence that can be used to inform scale-up of this program model that leverages existing community social networks and resources for improving caregivers' parenting skills and promoting ECD in rural Kenya and other similar settings across LMICs.

In-person versus remote (mHealth) delivery for a responsive parenting intervention in rural Kenya: a cluster randomized controlled trial

BACKGROUND

An estimated 43% of children under age 5 in low- and middle-income countries (LMICs) experience compromised development due to poverty, poor nutrition, and inadequate psychosocial stimulation. Numerous early childhood development (ECD) parenting interventions have been shown to be effective at improving ECD outcomes, at least in the short-term, but they are (a) still too expensive to implement at scale in low-resource and rural settings, and (b) their early impacts tend to fade over time. New approaches to deliver effective ECD parenting interventions that are low-cost, scalable, and sustainable are sorely needed.

METHODS

Our study will experimentally test a traditional in-person group-based delivery model for an evidence-based ECD parenting intervention against a hybrid-delivery model that increasingly substitutes in-person meetings with remote (mHealth) delivery via smartphones, featuring audiovisual content and WhatsApp social interactions and learning. We will assess the relative effectiveness and cost of this hybrid-delivery model compared to in-person delivery and will extend the interventions over two years to increase their ability to sustain changes in parenting behaviors and ECD outcomes longer-term. Our evaluation design is a cluster Randomized Controlled Trial (cRCT) across 90 villages and approximately 1200 households. Midline and endline surveys collected 12 and 24 months after the start of the interventions, respectively, will examine short- and sustained two-year intention-to-treat impacts on primary outcomes. We will also examine the mediating pathways using mediation analysis. We hypothesize that a hybrid-delivery ECD intervention will be lower in cost, but remote interactions among participants may be an inferior substitute for in-person visits, leaving open the question of the most cost-effective program.

DISCUSSION

Our goal is to determine the best model to maximize the intervention's reach and sustained impacts to improve child outcomes. By integrating delivery into the ongoing operations of local Community Health Promoters (CHPs) within Kenya's rural health care system, and utilizing new low-cost technology, our project has the potential to make important contributions towards discovering potentially scalable, sustainable solutions for resource-limited settings.

Effects of multi-component parenting and parental mental health interventions on early childhood development and parent outcomes: a systematic review and meta-analysis

BACKGROUND

Interventions supporting parents of young children often target parenting or parental mental health separately. Multi-component parenting and parental mental health interventions have the potential to improve parenting practices, mental health, and early childhood development. We aimed to examine their impact on child and parent outcomes.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE, Embase, Web of Science Core Collection, APA PsycINFO, CINAHL Complete, the Cochrane Central Register of Controlled Trials, and the Global Health Database from inception to Jan 23, 2024. Eligible studies were randomised controlled trials of interventions explicitly targeting parenting behaviours and parental mental health antenatally or in children's first 3 years of life. Screening, extraction, and quality assessment were done independently by two authors. Primary outcomes were cognitive and social-emotional functioning in children and depressive symptoms in parents, meta-analysed as standardised mean differences (SMDs), relative to control. This study is registered with PROSPERO, CRD42022302848.

FINDINGS

We found 5843 records. After screening 2636 (45·1%) titles and abstracts, we manually identified and screened three additional articles and excluded 2177 records. After screening 462 full-length articles, 25 articles, representing a sample size of 8520 children and caregivers, were included. At baseline, mean caregiver age was 27·7 years (SD 5·9) and mean child age (excluding those enrolled during pregnancy) was 14·4 months (8·0). Interventions lasted a mean of 14 months (SD 11) and used a mean of 3·7 behaviour change techniques (2·0). Most interventions dedicated more time to parenting behaviours than to parental mental health. We found significant intervention effects on children's cognitive (SMD 0·19 [95% CI 0·04 to 0·34]; I2=69%) and social-emotional (0·26 [0·17 to 0·34]; I2=47%) outcomes but not on depressive symptoms in female caregivers (-0·18 [-0·36 to 0·002]; I2=86%) relative to control conditions. Risk of bias across studies was moderate, and we found heterogeneity across results.

INTERPRETATION

Multi-component parenting and mental health interventions had a positive effect on child cognitive and social-emotional outcomes, but not on depressive symptoms in parents, suggesting that other factors might contribute to positive ECD outcomes. Interventions might lack adequate focus on mental health to make a discernible impact, highlighting a need for future studies to differentiate and assess contributions of parenting and mental health components to understand independent and collective effects on family outcomes.

Effects of Two Early Parenting Programmes on Child Aggression and Risk for Violence in Brazil: a Randomised Controlled Trial

Violence is a major public health problem globally, with the highest rates in low- and middle-income countries (LMICs) in the Americas and southern Africa. Parenting programmes in high-income countries can diminish risk for violence, by reducing risk factors such as child aggression and harsh parenting, and increasing protective factors such as child cognitive development and school readiness. However, there is critical need to identify low-cost programmes with replicable benefits that work in real-world LMICs contexts. A three-arm, randomised, single-blind trial evaluated effects of two low-cost, group-based parenting programmes recommended for LMICs (ACT: Raising Safe Kids; DBS: dialogic book-sharing) on child aggression (primary outcome), child development, parenting, maltreatment, and stress. Participants were 369 children with medium-high levels of aggression (mean age 3.1 years at baseline) in poor households. Interventions were implemented in city health and education services in southern Brazil. Maternal reports, filmed observations, child tasks, and hair cortisol were assessed at baseline, 1-month post-intervention, and 8-month follow-up. Intention-to-treat analyses compared each of ACT and DBS with a control group. Three hundred sixty-eight (99.7%) participants completed follow-up assessments 8 months after the interventions. There was no effect of ACT (standardised mean difference, SMD 0.11, 95% CI - 0.05, 0.27) or DBS (SMD 0.05, 95% CI - 0.11, 0.21) on the primary outcome of child aggression. ACT reduced harsh parenting behaviour post-intervention (SMD - 0.23; 95% CI - 0.46, - 0.01), but not at follow-up. DBS improved book-sharing practices at both time points (e.g., maternal sensitivity at follow-up SMD 0.33; 95% CI 0.08, 0.57). There were no benefits of either programme for other parenting, child development, or stress outcomes. Two parenting programmes in Brazil had small effects on parenting practices but did not reduce child aggression or several other important risk/protective factors for violence. Effective early interventions that reduce violence in real-world LMIC settings are highly desirable but may be challenging to achieve.

Family Club Denmark: A Quasi-Randomized Study of a Volunteer-Based Intervention to Support Vulnerable Families

Volunteer interventions play a vital role in supporting families by offering accessible and community-based resources outside the formal professional sector. This study examines the impact of the volunteer intervention known as Family Club Denmark (FCD) on the well-being of parents and children. FCD aims to provide families with positive experiences and support relationship building. The intervention, open to families from diverse social backgrounds, comprises volunteer-led family clubs where parents and children aged 2-12 years engage in activities and meals. We allocated 510 families (363 vulnerable families) to FCD or placed them on a waiting list based on a first-come, first-served principle. We conducted baseline, post-intervention, and follow-up assessments through questionnaires, observations, and interviews. On average, families participated in 5.8 sessions, with both families and volunteers reporting high satisfaction. When compared to control families, we find that vulnerable FCD parents feel more confident playing with their children (p = 0.04, [0.01; 0.40], d = 0.25), require less assistance in playing with their children (p = 0.01, [-0.34; -0.05], d = 0.33), and report that their children have a more challenging time forming friendships (p = 0.01, [-0.51; -0.09], d = 0.29). However, we did not find significant effects on mental health, parenting stress, self-efficacy, self-worth, family routines, or child well-being. We observed similar results for the full sample. The discovery that parents feel more confident playing with their children after participating in FCD highlights the vital role of volunteer-based interventions in enhancing parental engagement and fostering positive parent-child interactions.

Effects of engaging fathers and bundling parenting and nutrition interventions on early child development and maternal and paternal parenting in Mara, Tanzania: a factorial cluster-randomized controlled trial

BACKGROUND

Multicomponent interventions are needed to address the various co-occurring risks that compromise early child nutrition and development. We compared the independent and combined effects of engaging fathers and bundling parenting components into a nutrition intervention on early child development (ECD) and parenting outcomes.

METHODS

We conducted a 2×2 factorial cluster-randomized controlled trial across 80 villages in Mara Region, Tanzania, also known as EFFECTS (Engaging Fathers for Effective Child Nutrition and Development in Tanzania; ClinicalTrials.gov, NCT03759821). Households with children under 18 months of age residing with their mother and father were enrolled. Villages were randomly assigned to one of five groups: a nutrition intervention for mothers, a nutrition intervention for couples, a bundled nutrition and parenting intervention for mothers, a bundled intervention for couples, and a standard-of-care control. Interventions were delivered by trained community health workers through peer groups and home visits over 12 months. Mothers, fathers, and children were assessed at baseline, midline, and endline or postintervention. We used a difference-in-difference approach with intention-to-treat analysis to estimate intervention effects on ECD (Bayley Scales of Infant and Toddler Development, third edition) and maternal and paternal parenting and psychosocial well-being.

RESULTS

Between October 29, 2018, and May 24, 2019, 960 households were enrolled (n = 192 per arm). Compared to nutrition interventions, bundled interventions improved children's cognitive (β = .18 [95% CI: 0.01, 0.36]) and receptive language development (β = .23 [0.04, 0.41]). There were no differences between interventions for other ECD domains. Compared to nutrition interventions, bundled interventions achieved additional benefits on maternal stimulation (β = .21 [0.04, 0.38]) and availability of home learning materials (β = .25 [0.07-0.43]) and reduced paternal parenting distress (β = -.34 [-0.55, -0.12]). Compared to interventions with mothers only, interventions that engaged fathers improved paternal stimulation (β = .45 [0.27, 0.63]).

CONCLUSIONS

Jointly bundling parenting components into nutrition interventions while also engaging both mothers and fathers is most effective for improving maternal and paternal parenting and ECD outcomes.

Online educational intervention: Improving maternal knowledge and attitudes in providing developmental stimulation for stunting toddlers

Stunting remains a significant public health concern, impacting physical growth and impeding children's development. Mothers, who play a crucial role in stimulating children's development, often encounter barriers in providing effective stimulation, primarily due to limited access to appropriate resources and information. Online education can bridge this gap by offering easily accessible learning. This aim of this study was to determine the effect of online education on maternal knowledge and attitudes in providing developmental stimulation for stunting toddlers. A quasi-experimental research design was employed, comprising a treatment group and a control group, each consisting of 46 mothers with stunting toddlers, sampled purposively. The treatment group received an online developmental stimulation educational intervention through WhatsApp groups for twelve meetings, each lasting 1.5 to 2 hours. Meanwhile, the control group participated in a stunting assistance program provided by the community health centers (Puskesmas). To compare the knowledge and attitudes between groups, Mann-Whitney and independent Student t-test were used. The assessment of intervention effects on knowledge and attitudes was conducted using Wilcoxon and paired Student t-test within each group. Following the educational intervention on developmental stimulation, there was a significant increase in knowledge; however, there was no significant difference in attitudes. The treatment group (mean score 3.9±1.76) had a higher increase in knowledge scores compared to the control group (2.0±2.25) with a p<0.001. Nonetheless, no significant difference in attitudes was observed between the two groups with the mean change scores was 5.8±15.31 in treatment group and 2.5±18.69 for control group, with a p=0.335. This study suggests that providing online education leads to increased knowledge scores but does not impact attitudes significantly. Additional educational approaches should be considered to enhance maternal attitudes.

A meta-analytic review of the implementation characteristics in parenting interventions to promote early child development

This review summarizes the implementation characteristics of parenting interventions to promote early child development (ECD) outcomes from birth to 3 years. We included 134 articles representing 123 parenting trials (PROSPERO record CRD42022285998). Studies were conducted across high-income (62%) and low-and-middle-income (38%) countries. The most frequently used interventions were Reach Up and Learn, Nurse Family Partnership, and Head Start. Half of the interventions were delivered as home visits. The other half used mixed settings and modalities (27%), clinic visits (12%), and community-based group sessions (11%). Due to the lack of data, we were only able to test the moderating role of a few implementation characteristics in intervention impacts on parenting and cognitive outcomes (by country income level) in the meta-analysis. None of the implementation characteristics moderated intervention impacts on cognitive or parenting outcomes in low- and middle-income or high-income countries. There is a significant need in the field of parenting interventions for ECD to consistently collect and report data on key implementation characteristics. These data are needed to advance our understanding of how parenting interventions are implemented and how implementation factors impact outcomes to help inform the scale-up of effective interventions to improve child development.

A cluster randomised controlled trial of an early childhood parenting programme delivered through early childhood education centres in rural Zimbabwe

BACKGROUND

Early childhood is a critical period for child development. Effective approaches to support families in low-resource settings in the use of responsive and stimulating parenting are needed.

AIM

The aim of this study was to examine the effects of the Reach Up early childhood parenting programme on children's development, parenting attitudes and practices, when delivered through early childhood development (ECD) centres in Zimbabwe.

METHODS

A cluster randomised controlled trial was conducted in Sanyati, a rural district in Zimbabwe. Twenty-four of 51 available centres were randomised to intervention (n = 12) or control (n = 12) groups. Sixteen mothers with a child aged 12-30 months were recruited from each centre's catchment area (n = 189 intervention; n = 193 control). The intervention comprised two home visits per month delivered by centre teaching assistants over a period of 27 months. Primary outcomes were child Developmental Quotient (DQ), Language, Eye and Hand coordination, Performance and Practical Reasoning subscale scores assessed at follow-up. Secondary outcomes were mothers' attitudes about child development, parenting practices and maternal depressive symptoms all measured at baseline and follow-up. Intention to treat analyses was conducted using mixed-effects regression models with the standard error adjusted for cluster and inverse proportionality weights to adjust for attrition. Significance was set at P < 0.05.

RESULTS

A total of 285 (74.6%) of 382 children enrolled were tested, with 97 children lost to follow-up. The intervention improved the children's DQ by 3.55 points (95% CI 0.82 to 6.28), Eye and Hand by 3.58 (95% CI 0.59 to 6.56) and Practical Reasoning by 4.19 (95% CI 0.96 to 7.42). No significant improvements to Performance or Language scores, parenting attitudes, parenting practices and depressive symptoms were identified.

CONCLUSIONS

A home visiting intervention delivered by ECD teaching assistants promoted children's development. This suggests that outreach from preschools may be an effective platform for delivery of parenting interventions.

Primary-level and community worker interventions for the prevention of mental disorders and the promotion of well-being in low- and middle-income countries

BACKGROUND

There is a significant research gap in the field of universal, selective, and indicated prevention interventions for mental health promotion and the prevention of mental disorders. Barriers to closing the research gap include scarcity of skilled human resources, large inequities in resource distribution and utilization, and stigma.

OBJECTIVES

To assess the effectiveness of delivery by primary workers of interventions for the promotion of mental health and universal prevention, and for the selective and indicated prevention of mental disorders or symptoms of mental illness in low- and middle-income countries (LMICs). To examine the impact of intervention delivery by primary workers on resource use and costs.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, PsycInfo, WHO ICTRP, and ClinicalTrials.gov from inception to 29 November 2021.

SELECTION CRITERIA

Randomized controlled trials (RCTs) of primary-level and/or community health worker interventions for promoting mental health and/or preventing mental disorders versus any control conditions in adults and children in LMICs.

DATA COLLECTION AND ANALYSIS

Standardized mean differences (SMD) or mean differences (MD) were used for continuous outcomes, and risk ratios (RR) for dichotomous data, using a random-effects model. We analyzed data at 0 to 1, 1 to 6, and 7 to 24 months post-intervention. For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥ 0.80 large clinical effects. We evaluated the risk of bias (RoB) using Cochrane RoB2.

MAIN RESULTS

Description of studies We identified 113 studies with 32,992 participants (97 RCTs, 19,570 participants in meta-analyses) for inclusion. Nineteen RCTs were conducted in low-income countries, 27 in low-middle-income countries, 2 in middle-income countries, 58 in upper-middle-income countries and 7 in mixed settings. Eighty-three RCTs included adults and 30 RCTs included children. Cadres of primary-level workers employed primary care health workers (38 studies), community workers (71 studies), both (2 studies), and not reported (2 studies). Interventions were universal prevention/promotion in 22 studies, selective in 36, and indicated prevention in 55 RCTs. Risk of bias The most common concerns over risk of bias were performance bias, attrition bias, and reporting bias. Intervention effects 'Probably', 'may', or 'uncertain' indicates 'moderate-', 'low-', or 'very low-'certainty evidence. *Certainty of the evidence (using GRADE) was assessed at 0 to 1 month post-intervention as specified in the review protocol. In the abstract, we did not report results for outcomes for which evidence was missing or very uncertain. Adults Promotion/universal prevention, compared to usual care: - probably slightly reduced anxiety symptoms (MD -0.14, 95% confidence interval (CI) -0.27 to -0.01; 1 trial, 158 participants) - may slightly reduce distress/PTSD symptoms (SMD -0.24, 95% CI -0.41 to -0.08; 4 trials, 722 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD -0.69, 95% CI -1.08 to -0.30; 4 trials, 223 participants) Indicated prevention, compared to usual care: - may reduce adverse events (1 trial, 547 participants) - probably slightly reduced functional impairment (SMD -0.12, 95% CI -0.39 to -0.15; 4 trials, 663 participants) Children Promotion/universal prevention, compared to usual care: - may improve the quality of life (SMD -0.25, 95% CI -0.39 to -0.11; 2 trials, 803 participants) - may reduce adverse events (1 trial, 694 participants) - may slightly reduce depressive symptoms (MD -3.04, 95% CI -6 to -0.08; 1 trial, 160 participants) - may slightly reduce anxiety symptoms (MD -2.27, 95% CI -3.13 to -1.41; 1 trial, 183 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD 0, 95% CI -0.16 to -0.15; 2 trials, 638 participants) - may slightly reduce anxiety symptoms (MD 4.50, 95% CI -12.05 to 21.05; 1 trial, 28 participants) - probably slightly reduced distress/PTSD symptoms (MD -2.14, 95% CI -3.77 to -0.51; 1 trial, 159 participants) Indicated prevention, compared to usual care: - decreased slightly functional impairment (SMD -0.29, 95% CI -0.47 to -0.10; 2 trials, 448 participants) - decreased slightly depressive symptoms (SMD -0.18, 95% CI -0.32 to -0.04; 4 trials, 771 participants) - may slightly reduce distress/PTSD symptoms (SMD 0.24, 95% CI -1.28 to 1.76; 2 trials, 448 participants).

AUTHORS' CONCLUSIONS

The evidence indicated that prevention interventions delivered through primary workers - a form of task-shifting - may improve mental health outcomes. Certainty in the evidence was influenced by the risk of bias and by substantial levels of heterogeneity. A supportive network of infrastructure and research would enhance and reinforce this delivery modality across LMICs.

Measuring the cost-effectiveness of a home-visiting intervention to promote early child development among rural families linked to the Rwandan social protection system

Early childhood development (ECD) programmes are heralded as a way to improve children's health and educational outcomes. However, few studies in developing countries calculate the effectiveness of quality early childhood interventions. This study estimates the cost and cost-effectiveness of the Sugira Muryango (SM) trial, a home-visiting intervention to improve ECD outcomes through positive parent-child relationships. Cost-effectiveness analysis of ECD interventions is challenging given their potential to have multiple benefits. We propose a cost-effectiveness method using a single outcome, in this case the improvement in cognitive development per home-visit session, as an indication of efficiency comparable across similar interventions. The trial intervention cost US$456 per family. This cost will likely fall below US$200 if the intervention is scaled through government systems. The cost-effectiveness analysis suggests that while SM generated a relatively small impact on markers of early development, it did so efficiently. The observed improvements in cognitive development per home-visit are similar to other home-visiting interventions of longer duration. SM by focusing on the family had benefits beyond ECD, including reductions in violence against children and intermate partner violence, further analysis is needed to include these returns in the economic evaluation.

Interventions for child development based on the Touchpoints Model: scoping review

OBJECTIVE

to map the characteristics of interventions to promote child development that used the Touchpoints Model.

METHOD

this is a scoping review, guided by the recommendations of the JBI Reviewer's Manual, carried out in nine databases, in the gray literature and in the reference list of the selected studies. The research question was "what are the characteristics of interventions with parents/caregivers and children to promote child development, from pregnancy to six years of age, based on the Touchpoints Model?". Rayyan was used for the selection of studies and a standard form for data extraction. The analysis was carried out descriptively.

RESULTS

twelve publications were included in the review. Interventions were heterogeneous; concentrated in the period from pregnancy to three years of age; prioritized the dissemination of Touchpoints content according to age, and parenting aspects; most were performed by nurses, in Primary Health Care, and during home visits. Interventions were related to overall development, greater understanding of development and greater interaction with the child.

CONCLUSION

studies have shown potential for favorable outcomes for child development and parenting. The variability of interventions made it difficult to map more effective characteristics. (1) Interventions in the period of pregnancy until the child's 3 years of life predominated. (2) Interventions by nurses in Primary Care and home visits predominated. (3) The interventions were mostly delivered individually and face-to-face. (4) The participating parents had a greater understanding of child development. (5) There was more interaction with the child, use of toys and learning materials.

Pathways to scale up early childhood programs: A scoping review of Reach Up and Care for Child Development

Evidence-based early childhood development (ECD) programs that strengthen nurturing parenting skills and promote early stimulation, such as Reach Up (RU) and Care for Child Development (CCD), are critical investments for interrupting cycles of intergenerational poverty; however, the implementation impact of these programs varies greatly globally. Analyzing systematically the evidence on the implementation pathways based on contexts (i.e., external and internal influences on intervention implementation), implementation strategies (i.e., mechanisms used to promote program initiation, design, and delivery with existing systems), and implementation outcomes (i.e., related to the implementation goals) can increase the likelihood of implementation success. Our scoping review aimed to identify implementation pathways of RU and CCD programs in low- and middle-income countries. A search in English, Spanish, and Portuguese of grey literature and five databases of peer reviewed literature; from inception through July 16, 2022, yielded 2,267 publications. Using predetermined eligibility criteria, 75 records yielded implementation details for 33 programs across 23 low- and middle-income countries. Two reviewers independently extracted program data on context, implementation strategies, and implementation outcomes following a program theory. A thematic analysis identified 37 implementation strategies across six "building blocks of implementation": program emergence, intersectoriality, intervention characteristics, workforce, training, and monitoring systems. Implementation pathways across building blocks are highly influenced by contextual factors, such as infrastructure, social norms, and the target population's demand and interest, which may shape different implementation outcomes. Six 'building blocks' shaping implementation pathways of CCD and RU in LMICs were identified. The careful consideration of context and use of intentional evidence-based planning can enable the successful implementation of ECD nurturing care interventions. We recommend the use of the ECD Implementation Checklist for Enabling Program Scale Up to guide decision-making regarding context and implementation strategies to support implementation outcomes and subsequent ECD program success.

Formative research to inform the future design of a multicomponent fatherhood intervention to improve early child development in Mwanza, Tanzania

Fathers can influence child development through various pathways, such as via their caregiving behaviors, marital relationships, and their psychosocial wellbeing. However, few parenting interventions have been designed to target these multiple dimensions among fathers with young children in low- and middle-income countries. In June 2022, we conducted qualitative formative research to explore the perceptions surrounding fatherhood and the underlying barriers and enablers to engaged fathering in Mwanza, Tanzania. We completed individual in-depth interviews with 29 fathers and 23 mothers of children under aged 2 years along with 5 community leaders and 3 community health workers. We also completed 10 focus group discussions: 4 with fathers, 2 with mothers, and 4 mixed groups that combined both fathers and mothers. In total, the sample included 120 respondents stratified from across 4 study communities. Data were analyzed using thematic content analysis. Respondents highlighted that poor couples' relationships (e.g., limited male partner support, male dominance in decision-making) and fathers' mental health problems (e.g., parenting stress) were major priorities affecting fathers. Father involvement in parenting, childcare, and household activities were generally low. These dimensions of fatherhood were interlinked (e.g., poor paternal mental health constrained marital relationships and parenting). A constellation of determinants impacted engaged fathering. Common barriers included poverty, restrictive gender attitudes and norms, men's limited time at home, and inadequate knowledge about caregiving. Key enablers included mutual respect in marital relationships and men's desires to show their love for their families. Our results highlight the cultural relevance and the need for multicomponent strategies that jointly target fathers' caregiving, marital relationships, and psychosocial wellbeing for enhancing nurturing care and promoting early child development in Tanzania. Study findings can be used to inform the design of a future father-inclusive, gender-transformative parenting intervention for engaging and supporting fathers with young children in the local cultural context.

Effectiveness of father-inclusive interventions on maternal, paternal, couples, and early child outcomes in low- and middle-income countries: A systematic review

Most caregiving interventions for young children are directed to female caregivers. Relatively few have included male caregivers as program participants especially in low- and middle-income countries (LMICs). The range of potential benefits that can be achieved through the engagement of fathers and male caregivers has not been adequately explored from a family systems perspective. We reviewed interventions that engaged male caregivers to support young children in LMICs and summarized impacts on maternal, paternal, couples, and child outcomes. We searched MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, and Global Health Library for quantitative evaluation studies of social and behavioral interventions that included fathers or other male caregivers to improve nurturing care for young children under 5 years of age in LMICs. Three authors independently extracted data using a structured form. Forty-four articles, representing 33 intervention evaluations, were included. The most common type of intervention targeted fathers along with their female partners and primarily to address child nutrition and health. Across interventions, maternal outcomes were the most evaluated outcomes (82%), followed by paternal (58%), couple's relationship (48%) and child-level outcomes (45%). Overall, father-inclusive interventions had positive impacts on maternal, paternal and couples' relationship outcomes. Although there was greater variation in the degree of supportive evidence for child outcomes compared to maternal, paternal, and couples outcomes, findings suggested mostly positive effects across all outcomes. Limitations included relatively weak study designs and heterogeneity across interventions, outcome types, and measurement tools. Interventions that include fathers and other male caregivers have potential to improve maternal and paternal caregiving, couple's relationships dynamics, and early child outcomes in LMICs. More evaluation studies, using rigorous methods and robust measurement frameworks, is needed to bolster this evidence-base about the effect of fathers' engagement for young children, caregivers, and families in LMICs.

The Reach Up Parenting Program, Child Development, and Maternal Depression: A Meta-analysis

BACKGROUND AND OBJECTIVES

Evidence is needed on effective approaches to build parents' ability to promote child development feasible in low- and middle-income countries. Our objective was to synthesize impact of the Reach Up early childhood parenting program in several low- and middle-income countries and examine moderation by family and implementation characteristics.

METHODS

Systematic search using PubMed and Academic Search Elite/EBSCO Host. Randomized controlled trials of the Reach Up program from 1985 to February 2022 were selected. Data were extracted by 2 independent researchers. Primary outcomes were child cognitive, language, and motor development. Secondary outcomes were home stimulation and maternal depressive symptoms. We synthesized pooled effect sizes using random effect inverse-variance weighting and effect modification by testing pooled subgroup effect estimates using the χ2 test for heterogeneity.

RESULTS

Average effect size across 18 studies ranged from 0.49 (95% confidence interval [CI] 0.32 to 0.66) for cognition, 0.38 (CI 0.24 to 0.51) for language, 0.27 (CI 0.13 to 0.40) for motor development, 0.37 (CI 0.21 to 0.54) for home stimulation, and -0.09 (CI -0.19 to 0.01) for maternal depressive symptoms. Impacts were larger in studies targeted to undernourished children, with mean enrollment older than age 12 months and intervention duration 6 to 12 months. Quality of evidence assessed with the Cochrane Assessment of Risk of Bias and GRADE system was moderate. Instruments used to assess child development varied. In moderator analyses, some subgroups included few studies.

CONCLUSIONS

Reach Up benefits child development and home stimulation and is adaptable across cultures and delivery methods. Child and implementation characteristics modified the effects, with implications for scaling.

Structured, multicomponent, community-based programme for women's health and infant health and development in rural Vietnam: a parallel-group cluster randomised controlled trial

BACKGROUND

Interventions to improve early childhood development have previously addressed only one or a few risk factors. Learning Clubs is a structured, facilitated, multicomponent programme designed to address eight potentially modifiable risk factors, and offered from mid-pregnancy to 12 months post partum; we aimed to establish whether this programme could improve the cognitive development of children at 2 years of age.

METHODS

For this parallel-group cluster-randomised controlled trial, 84 of 116 communes (the clustering unit) in HaNam Province in rural Vietnam were randomly selected and randomly assigned to receive the Learning Clubs intervention (n=42) or usual care (n=42). Women aged at least 18 years who were pregnant (gestational age <20 weeks) were eligible for inclusion. Data sources were standardised, and study-specific questionnaires assessing risks and outcomes were completed in interviews in mid-pregnancy (baseline), late pregnancy (after 32 weeks of gestation), at 6-12 months post partum, and at the end of the study period when children were 2 years of age. Mixed-effects models were used to estimate trial effects, adjusting for clustering. The primary outcome was the cognitive development of children at 2 years of age, assessed by the Bayley Scales of Infant and Toddler Development Third Edition (Bayley-III) cognitive score. This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12617000442303).

FINDINGS

Between April 28, 2018, and May 30, 2018, 1380 women were screened and 1245 were randomly assigned (669 to the intervention group and 576 to the control group). Data collection was completed on Jan 17, 2021. Data at the end of the study period were contributed by 616 (92%) of 669 women and their children in the intervention group, and by 544 (94%) of 576 women and their children in the control group. Children aged 2 years in the intervention group had significantly higher mean Bayley-III cognitive scores than those in the control group (99·6 [SD 9·7] vs 95·6 [9·4]; mean difference 4·00 [95% CI 2·56-5·43]; p<0·0001). At 2 years of age, 19 (3%) children in the intervention group had Bayley-III scores less than 1 SD, compared with 32 (6%) children in the control group, but this difference was not significant (odds ratio 0·55 [95% CI 0·26-1·17]; p=0·12). There were no significant differences between groups in maternal, fetal, newborn, or child deaths.

INTERPRETATION

A facilitated, structured, community-based, multicomponent group programme improved early childhood development to the standardised mean in rural Vietnam and could be implemented in other similarly resource-constrained settings.

An Integrated Mother-Child Intervention on Child Development and Maternal Mental Health

OBJECTIVES

To evaluate an integrated, low-cost, facility-based group intervention designed to promote child care, boost maternal mental-wellbeing, reduce harsh discipline, and improve children's health, nutrition, and early development.

METHODS

In Dhaka, 30 neighborhood clusters of a low-income urban community were randomized to intervention or control groups. Mothers with children between 6 and 24 months (n = 300) who self-reported negative discipline were identified and enrolled. A 1-year group intervention included integration of responsive caregiving, nutritional supplementation, caregivers' mental health, child protection, and health advice. Child outcomes were cognition (primary) and language, motor and behavioral development, growth, and hemoglobin and iron status (secondary). Maternal outcomes were depressive symptoms, self-esteem, negative discipline, and child care knowledge and practices.

RESULTS

Overall, 222 (74%) mother-child dyads participated in the 1-year follow-up. Intervention and control groups differed on wealth, with no other significant differences. The intervention resulted in a 0.75 SD effect on cognition, 0.77 SD on language, 0.41 SD on motor, and 0.43 to 0.66 SDs on behavior during testing (emotion, cooperation, and vocalization) in the intervention arm. Mothers in the intervention group had fewer depressive symptoms (effect size: -0.72 SD), higher self-esteem (0.62 SD), better child care knowledge (2.02 SD), fewer harsh discipline practices (0.25 SD), and better home stimulation (0.73 SD). The intervention showed no effect on child growth or hemoglobin, but significantly improved serum iron status (-0.36 SD).

CONCLUSIONS

A comprehensive intervention, delivered through group sessions in health facilities, was effective in promoting child development and reducing maternal depressive symptoms among mothers who reported using negative or harsh discipline.

The Effect of Parenting Peer Education Interventions for Young Mothers on the Growth and Development of Children under Five

One of the contributing factors in the growth and development of children under five is the mother's ability to provide childcare, but young mothers do not have enough parenting skills. The goal of the current study was to examine the effect of the parenting peer education (PPE) programme on young mothers' parenting self-efficacy and behaviour, and the growth and development of children under five. There were two groups, which were a control group (without intervention) and an intervention group, in which there were 15 participants in each group. Analysis covariance with the pre-test scores as covariates was used in this study. The results showed that, compared with the control group, the intervention group reported significantly better parenting self-efficacy, parenting behaviour, children's growth, and children's development, including cognitive, language, and motoric aspects. The PPE programme can exchange the young mothers' experiences on how their children grow and develop, and the mothers will also receive psychological support. In conclusion, the PPE programme affected the young mothers' parenting self-efficacy and parenting behaviour and the children's growth and development.

Effectiveness and cost-effectiveness of a group-based intervention to improve social-emotional development of young children in poverty-stricken areas: A cluster randomized controlled trial

Background

Social-emotional ability is key to the well-being and future success of children; however, disparities in social-emotional development during an individual's early age can last a lifetime, which is particularly evident among children living in poverty-stricken areas. We aimed to determine the effectiveness, cost-effectiveness, and feasibility of a group-based intervention called the Care Group on social-emotional development for families living in poverty-stricken counties.

Methods

We conducted a cluster (township) randomized controlled trial (C-RCT) every two weeks from July 2019 to June 2020 in a poverty-stricken area located in Shanxi, China. The outbreak of the COVID-19 pandemic suspended the implementation of the intervention in January 2020. The caregiver-child pairs in the intervention group participated in 12 group-based sessions with a structured curriculum and learning materials emphasizing nurturing ability and early childhood development. We applied a difference-in-differences (DID) model to estimate the intervention's impact. The analysis follows the intention-to-treat (ITT) principle. We used standard economic costing methods to estimate the cost of implementing the Care Group over the intervention period and adopted a societal perspective in the analysis.

Results

We included 322 eligible caregiver-child pairs in the baseline (intervention n = 136, control n = 186) and surveyed 258 pairs in the endline (intervention n = 117, control n = 141). Compared with the control group, children in the intervention group had significantly fewer social-emotional problems (adjusted mean difference of Z score = -0.374, 95% CI = -0.718, -0.030, P = 0.033) six months after intervention. In the first year, the annual cost of implementing Care Group was US$146.10 per child, reduced to US$47.20 per child in the second year due to the exclusion of non-recurrent costs. The incremental cost-effectiveness ratio (ICER) was US$390.60.

Conclusions

Care Group is an effective approach for promoting children's social-emotional development in poverty-stricken areas at an affordable cost and with high feasibility for scale-up. Considering the planned per capita health expenditure of the Chinese government for 2022, we believe that the presented evidence makes a solid scientific and financial case for integrating the Care Group intervention into the basic public health services (BPHS) package.

Implementation characteristics of father-inclusive interventions in low- and middle-income countries: A systematic review

Although prior reviews have documented the effectiveness of engaging male caregivers in early childhood interventions, little is known about how these interventions have been designed and implemented to reach, engage, and support male caregivers in low-resource global settings. We searched five bibliographic databases for intervention studies that engaged male caregivers to improve nurturing care for children under 5 years of age in low- and middle-income countries. Forty-four articles met the inclusion criteria, which represented 33 interventions. Fathers specifically were the most common type of male caregivers targeted in these interventions. The majority of interventions invited fathers to participate alongside their female partners. Community-based peer-groups were the most common delivery model. Most interventions used the same program structure for fathers as applied to mothers, with few considering whether implementation adaptations were needed for men. Intervention curricula were multicomponent and largely targeted child nutrition, health, and couples' relationships. A minority of programs addressed parenting, psychosocial wellbeing, violence prevention, gender attitudes, or economic support. Behavior change techniques were limited to interactive counseling and peer learning. Male caregivers remain missing from caregiving interventions for young children. A greater focus on implementation research can inform better inclusion, engagement, and support for male caregivers in nurturing care interventions.

Educational interventions in child development and health literacy assumptions: an integrative review

OBJECTIVES

to analyze scientific evidence in the literature that addresses educational interventions conducted by health professionals on early childhood development in a community context and to identify which health literacy assumptions are present during the implementation of interventions.

METHOD

an integrative review in PubMed, CINAHL and Web of Science databases. Of 300 studies found, we selected 11 for the sample.

RESULTS

health professionals are trained to implement interventions with parents/caregivers to promote child development in community settings. Parents are encouraged to develop an environment that is encouraging and conducive to the development of their children. The main dimensions of health literacy found were access and apply.

CONCLUSION

it confirms the importance of training health professionals, with skills and communicative skills to guide parents/caregivers to encourage the development of their children in their family environment with playful and interactive activities.

Effect of parenting intervention through "Care for Child Development Guideline" on early child development and behaviors: a randomized controlled trial

BACKGROUND

Several studies showed that parenting intervention programs play a core component in early child development. Considering the limited healthcare resources in developing countries, group-session intervention based on care for child development (CCD) guideline might be cost-effective.

METHODS

This randomized controlled trial was conducted at an outpatient public Pediatrics clinic in Isfahan, Iran. We included 210 pregnant women aged 18-45 years in their third trimester and followed their children for 18 months. The intervention group underwent 5 educational group sessions, each lasting for almost 45 minutes. The main outcomes were the children's development and socio-emotional behavior problems based on Bayley Scales of Infant and Toddler Development-III (BSID-III) at 12 months and the Children Behavior Checklist (CBCL) at 18 months.

RESULTS

Overall, data of 181 children were included in the current study, including 80 in the intervention group and 101 controls. The adjusted median/mean differences between intervention and control groups using median/linear regression were not significant for all BSID-III domains except for median differences for cognitive score based on BSID-III (β (SE): - 4.98(2.31), p:0.032) and mean differences for anxiety/depression score based on CBCL (β (SE): - 2.54(1.27), p:0.046).

CONCLUSION

In this study, parenting interventions through CCD group sessions were significantly effective on just one subscale of children's socio-emotional behavior domains based on CBCL and one domain of children's development based on BSID-III. There might be a ceiling or floor effects for the BSID-III and CBCL assessment, respectively, leaving little room for improvement as almost all children have achieved their full developmental potential in our study.

Impact of an Early Childhood Development Intervention on the Mental Health of Female Caregivers: Evidence from a Randomized Controlled Trial

Investing in early childhood development is an effective way to enhance human capital accumulation. Caregivers' mental health is one of the most important factors influencing children's development. Previous studies have found that mental health issues in caregivers are widespread all over the world, especially in low- and middle-income countries. In this study, we explored the effects of the "Integrated Program for Early Childhood Development" on the mental health of female caregivers in Southwest China through a randomized intervention trial, with infants aged 5-25 months and their caregivers as the target subjects. The heterogeneity of the effects of different characteristics of the caregivers and the mechanism of the intervention effect were also analyzed. Primary caregivers were provided comprehensive early development interventions for the children in the treatment group via bi-weekly home visiting activities and monthly family group activities. The results showed that the prevalence of depression, anxiety, and stress symptoms among female caregivers in this rural area were 32%, 42%, and 30%, respectively. Whether the child was breastfed, parent's age, parent's education level, primary caregiver type, the ratio of the number of months the mother was at home full time to the child's age, the grandmother's rearing ability, and the family asset index were the factors influencing the mental health of female caregivers. The intervention significantly increased the proportion of depressive symptoms in 28% of the grandmothers. It significantly reduced the anxiety symptoms of daughters-in-law not from the local town, while the social interactions of both local and non-local daughters-in-law were significantly improved.

Integrating a Group-Based, Early Childhood Parenting Intervention Into Primary Health Care Services in Rural Bangladesh: A Cluster-Randomized Controlled Trial

Background

Over 250 million children globally do not reach their developmental potential. We tested whether integrating a group-based, early childhood parenting program into government healthcare clinics improved children's development, growth, and behavior.

Methods

We conducted a cluster-randomized controlled trial in 40 community clinics in the Kishorganj district of Bangladesh. We randomly assigned clinics (1:1) to deliver a group-based parenting interventions or to a comparison group that received no intervention. Participants were children aged 5-24 months, with weight-for-age z-score of ≤ -1.5 SDs of the WHO standards, living within a thirty-minute walking distance from the clinic (n = 419 intervention, 366 control). Government health staff facilitated parenting sessions in the clinic with groups of four mother/child dyads fortnightly for one year as part of their routine duties. Primary outcomes measured at baseline and endline were child development assessed using the Bayley scales, child behaviors during the test by tester ratings, and child growth. The trial is registered at ClinicalTrials.gov, NCT02208531.

Findings

91% of children were tested at endline (396 intervention, 319 control). Multilevel analyses showed significant benefits of intervention to child cognition (effect size 0.85 SDs, 95% CI: 0.59, 1.11), language (0.69 SDs, 0.43, 0.94), and motor development (0.52 SDs, 0.31, 0.73), and to child behaviors during the test (ranging from 0.36 SDs, 0.14, 0.58, to 0.53 SDs, 0.35, 0.71). There were no significant effects on growth.

Conclusion

A scalable parenting intervention, integrated into existing government health services and implemented by government health staff, led to significant benefits to child development and behavior.

Father involvement and early child development in a low-resource setting

Evidence on the role of father involvement in children’s development from low-resource settings is very limited and historically has only relied on maternal reports of father’s direct engagement activities such as reading to the child. However, fathers can also potentially influence their children’s development via greater positive involvement with the mother, such as by offering interpersonal support or sharing decision-making duties. Such positive intrahousehold interactions can benefit maternal mental health and wellbeing, and ultimately children’s development. We use data collected from mothers, fathers and children in the context of the cluster randomized controlled trial evaluation of Msingi Bora, a responsive parenting intervention implemented across 60 villages in rural western Kenya, to explore the various pathways through which fathers may influence their children’s outcomes. In an endline survey in Fall 2019 among a sample of 681 two-parent households with children aged 16–34 months, fathers reported on measures of their behaviors towards children and with mothers, mothers reported on their wellbeing and behaviors, and interviewers assessed child cognitive and language development with the Bayley Scales. In adjusted multivariate regression analyses we found that greater father interpersonal support to mothers and greater participation in shared household decision-making were positively associated with children’s development. These associations were partially mediated through maternal wellbeing and behaviors. We found no association between fathers’ direct engagement in stimulation activities with children and children’s outcomes. Inviting fathers to the program had no impact on their involvement or on any maternal or child outcomes, and fathers attended sessions at low rates. Overall, our results show the potential promises and challenges of involving fathers in a parenting intervention in a rural low-resource setting. Our findings do highlight the importance of considering intrahousehold pathways of influence in the design of parenting interventions involving fathers.

Parenting centers and caregiver mental health: Evidence from a large-scale randomized controlled trial in China

This study conducts an exploratory analysis of the impacts of a center-based early childhood development intervention on the mental health of caregivers, using data from a cluster-randomized controlled trial of 1664 caregivers (M_age  = 36.87 years old) of 6- to 24-month-old children in 100 villages in rural China. Caregivers and children in 50 villages received individual parenting training, group activities and open play space in village parenting centers. The results show no significant overall change in caregiver-reported mental health symptoms after 1 year of intervention. Subgroup analyses reveal heterogeneous effects by caregiver socioeconomic status and identity (mother vs. grandmother). Findings suggest that early childhood development interventions without targeted mental health components may not provide sufficient support to improve caregiver mental health.

Child diet and mother-child interactions mediate intervention effects on child growth and development

This study examined whether child diet and mother-child interactions mediated the effects of a responsive stimulation and nutrition intervention delivered from 2009 to 2012 to 1324 children aged 0-24 months living in rural Pakistan. Results showed that the intervention improved children's cognitive, language and motor development through child diet and mother-child interactions. Although the intervention did not improve child growth or socio-emotional development, we observed positive indirect effects on child growth via child diet and on socio-emotional development via both child diet and mother-child interactions. In addition, child diet emerged as a shared mechanism to improve both child growth and development, whereas mother-child interactions emerged as a distinct mechanism to improve child development. Nevertheless, our results suggest the two mechanisms were mutually reinforcing and that interventions leveraging both mechanisms are likely to be more effective at improving child outcomes than interventions leveraging only one of these mechanisms.

A pilot to promote early child development within health systems in Mozambique: a qualitative evaluation

Health systems offer unique opportunities for integrating services to promote early child development (ECD). However, there is limited knowledge about the implementation experiences of using health services to target nurturing care and ECD, especially in sub-Saharan Africa. We conducted a qualitative implementation evaluation to assess the delivery, acceptability, perceived changes, and barriers and facilitators associated with a pilot strategy that integrated developmental monitoring, nutritional screening, and early learning and nutrition counseling into the existing health facility, and community-based services for young children in rural Mozambique. We completed individual interviews with caregivers (N = 36), providers (N = 27), and district stakeholders (N = 10), and nine facility observational visits at three primary health facilities in October-November 2020. We analyzed data using thematic content analysis. Results supported fidelity to the intended pilot model and acceptability of nurturing care services. Respondents expressed various program benefits, including strengthened health system capacity and improved knowledge, attitudes, and practices regarding nurturing care and ECD. Government leadership and supportive supervision were key facilitators, whereas health system resource constraints were key barriers. We conclude that health systems are promising platforms for supporting ECD and discuss several programmatic recommendations for enhancing service delivery and maximizing potential impacts on nurturing care and ECD outcomes.

Need for more evidence in the prevention and management of perinatal asphyxia and neonatal encephalopathy in low and middle-income countries: A call for action

Although low- and middle-income countries (LMICs) shoulder 90 % of the neonatal encephalopathy (NE) burden, there is very little evidence base for prevention or management of this condition in these settings. A variety of antenatal factors including socio-economic deprivation, undernutrition and sub optimal antenatal and intrapartum care increase the risk of NE, although little is known about the underlying mechanisms. Implementing interventions based on the evidence from high-income countries to LMICs, may cause more harm than benefit as shown by the increased mortality and lack of neuroprotection with cooling therapy in the hypothermia for moderate or severe NE in low and middle-income countries (HELIX) trial. Pooled data from pilot trials suggest that erythropoietin monotherapy reduces death and disability in LMICs, but this needs further evaluation in clinical trials. Careful attention to supportive care, including avoiding hyperoxia, hypocarbia, hypoglycemia, and hyperthermia, are likely to improve outcomes until specific neuroprotective or neurorestorative therapies available.

Cost-effectiveness and economic returns of group-based parenting interventions to promote early childhood development: Results from a randomized controlled trial in rural Kenya

BACKGROUND

Early childhood development (ECD) programs can help address disadvantages for the 43% of children under 5 in low- and middle-income countries (LMICs) experiencing compromised development. However, very few studies from LMIC settings include information on their program's cost-effectiveness or potential returns to investment. We estimated the cost-effectiveness, benefit-cost ratios (BCRs), and returns on investment (ROIs) for 2 effective group-based delivery models of an ECD parenting intervention that utilized Kenya's network of local community health volunteers (CHVs).

METHODS AND FINDINGS

Between October 1 and November 12, 2018, 1,152 mothers with children aged 6 to 24 months were surveyed from 60 villages in rural western Kenya. After baseline, villages were randomly assigned to one of 3 intervention arms: a group-only delivery model with 16 fortnightly sessions, a mixed-delivery model combining 12 group sessions with 4 home visits, and a control group. At endline (August 5 to October 31, 2019), 1,070 children were retained and assessed for primary outcomes including cognitive and receptive language development (with the Bayley Scales of Infant Development, Third Edition) and socioemotional development (with the Wolke scale). Children in the 2 intervention arms showed better developmental outcomes than children in the control arm, although the group-only delivery model generally had larger effects on children. Total program costs included provider's implementation costs collected during the intervention period using financial reports from the local nongovernmental organization (NGO) implementer, as well as societal costs such as opportunity costs to mothers and delivery agents. We combined program impacts with these total costs to estimate incremental cost-effectiveness ratios (ICERs), as well as BCRs and the program's ROI for the government based on predictions of future lifetime wages and societal costs. Total costs per child were US$140 in the group-only arm and US$145 in the mixed-delivery arm. Because of higher intention-to-treat (ITT) impacts at marginally lower costs, the group-only model was the most cost-effective across all child outcomes. Focusing on child cognition in this arm, we estimated an ICER of a 0.37 standard deviation (SD) improvement in cognition per US$100 invested, a BCR of 15.5, and an ROI of 127%. A limitation of our study is that our estimated BCR and ROI necessarily make assumptions about the discount rate, income tax rates, and predictions of intervention impacts on future wages and schooling. We examine the sensitivity of our results to these assumptions.

CONCLUSIONS

To the best of our knowledge, this study is the first economic evaluation of an effective ECD parenting intervention targeted to young children in sub-Saharan Africa (SSA) and the first to adopt a societal perspective in calculating cost-effectiveness that accounts for opportunity costs to delivery agents and program participants. Our cost-effectiveness and benefit-cost estimates are higher than most of the limited number of prior studies from LMIC settings providing information about costs. Our results represent a strong case for scaling similar interventions in impoverished rural settings, and, under reasonable assumptions about the future, demonstrate that the private and social returns of such investments are likely to largely outweigh their costs.

Supporting Child Development Through Parenting Interventions in Low- to Middle-Income Countries: An Updated Systematic Review

Background: Over 250 million children in low- and middle-income countries are at risk of not achieving their fullest developmental potential due to co-occurring risks such as poor nutrition and inadequate learning opportunities. Early intervention programs integrating the aspects of nurturing care, that is, good health, adequate nutrition, safety and security, responsive caregiving, and learning opportunities, may ameliorate against the negative impact of these adverse conditions. Methods: This meta-analytic review updates the evidence base of parenting interventions comprising stimulation and responsive caregiving components on developmental outcomes for children under age 2 years in low- and middle-income countries. It also describes and assesses the moderation effects of population characteristics and implementation features on the intervention effectiveness. Studies were identified based on previous systematic reviews and an updated literature search in eight databases and the gray literature up to December 2020. A random-effect model was used to explore the pooled effect sizes accounted for by the intervention for developmental outcome of cognition, language, motor, and social-emotional capacities. Exploratory moderation analyses were also conducted. Results: Twenty-one randomized controlled trials representing over 10,400 children from 12 low- and middle-income countries and regions across three continents (Africa, Latin America, and Asia) were identified. The interventions showed overall small-to-moderate effects on children's cognitive development (ES = 0.44; 95% CI = [0.30, 0.57]); language development (ES = 0.33; 95% CI = [0.18, 0.49]); and motor skills (ES = 0.21; 95% CI = [0.10, 0.32]). The overall effect on social-emotional development was non-significant (ES = 0.17; 95% CI = [-0.01, 0.34]). Effect sizes (ES) varied significantly across the studies. Parenting programs that targeted vulnerable groups, including rural communities and caregivers with lower education levels, had more significant effects on children's development. Group sessions (vs. individual visits) and high program dose (≥12 sessions) were also associated with stronger effects on child development. Further research is needed to determine the effectiveness of the workforce and training on programmatic outcomes. Conclusion: The findings indicate that parenting interventions that encourage nurturing care are effective in improving the early development of children, especially among vulnerable populations. We discuss opportunities to strengthen the implementation of research-based parenting interventions in such contexts.

A holistic approach to promoting early child development: a cluster randomised trial of a group-based, multicomponent intervention in rural Bangladesh

Introduction

In low- and middle-income countries, children experience multiple risks for delayed development. We evaluated a multicomponent, group-based early child development intervention including behavioural recommendations on responsive stimulation, nutrition, water, sanitation, hygiene, mental health and lead exposure prevention.

Methods

We conducted a 9-month, parallel, multiarm, cluster-randomised controlled trial in 31 rural villages in Kishoreganj District, Bangladesh. Villages were randomly allocated to: group sessions (‘group’); alternating groups and home visits (‘combined’); or a passive control arm. Sessions were delivered fortnightly by trained community members. The primary outcome was child stimulation (Family Care Indicators); the secondary outcome was child development (Ages and Stages Questionnaire Inventory, ASQi). Other outcomes included dietary diversity, latrine status, use of a child potty, handwashing infrastructure, caregiver mental health and knowledge of lead. Analyses were intention to treat. Data collectors were independent from implementers.

Results

In July–August 2017, 621 pregnant women and primary caregivers of children<15 months were enrolled (group n=160, combined n=160, control n=301). At endline, immediately following intervention completion (July–August 2018), 574 participants were assessed (group n=144, combined n=149, control n=281). Primary caregivers in both intervention arms participated in more play activities than control caregivers (age-adjusted means: group 4.22, 95% CI 3.97 to 4.47; combined 4.77, 4.60 to 4.96; control 3.24, 3.05 to 3.39), and provided a larger variety of play materials (age-adjusted means: group 3.63, 3.31 to 3.96; combined 3.81, 3.62 to 3.99; control 2.48, 2.34 to 2.59). Compared with the control arm, children in the group arm had higher total ASQi scores (adjusted mean difference in standardised scores: 0.39, 0.15 to 0.64), while in the combined arm scores were not significantly different from the control (0.25, –0.07 to 0.54).

Conclusion

Our findings suggest that group-based, multicomponent interventions can be effective at improving child development outcomes in rural Bangladesh, and that they have the potential to be delivered at scale.

An Implementation Evaluation of A Group-Based Parenting Intervention to Promote Early Childhood Development in Rural Kenya

Early childhood development (ECD) parenting interventions can improve child developmental outcomes in low-resource settings, but information about their implementation lags far behind evidence of their effectiveness, hindering their generalizability. This study presents results from an implementation evaluation of Msingi Bora ("Good Foundation" in Swahili), a group-based responsive stimulation and nutrition education intervention recently tested in a cluster randomized controlled trial across 60 villages in rural western Kenya. Msingi Bora successfully improved child cognitive, receptive language, and socioemotional outcomes, as well as parenting practices. We conducted a mixed methods implementation evaluation of the Msingi Bora trial between April 2018 and November 2019 following the Consolidated Advice for Reporting ECD implementation research (CARE) guidelines. We collected qualitative and quantitative data on program inputs, outputs, and outcomes, with a view to examining how aspects of the program's implementation, such as program acceptance and delivery fidelity, related to observed program impacts on parents and children. We found that study areas had initially very low levels of familiarity or knowledge of ECD among parents, community delivery agents, and even supervisory staff from our partner non-governmental organization (NGO). We increased training and supervision in response, and provided a structured manual to enable local delivery agents to successfully lead the sessions. There was a high level of parental compliance, with median attendance of 13 out of 16 fortnightly sessions over 8 months. For delivery agents, all measures of delivery performance and fidelity increased with program experience. Older, more knowledable delivery agents were associated with larger impacts on parental stimulation and child outcomes, and delivery agents with higher fidelity scores were also related to improved parenting practices. We conclude that a group-based parenting intervention delivered by local delivery agents can improve multiple child and parent outcomes. An upfront investment in training local trainers and delivery agents, and regular supervision of delivery of a manualized program, appear key to our documented success. Our results represent a promising avenue for scaling similar interventions in low-resource rural settings to serve families in need of ECD programming.

Impact of Home Parenting Environment on Cognitive and Psychomotor Development in Children Under 5 Years Old: A Meta-Analysis

This study aims to evaluate the relationship between home parenting environment and the cognitive and psychomotor development in children under 5 years old by using meta-analysis. A systematic search of the Chinese and English databases including Pubmed, Embase, the Cochrane Library, CNKI, Weipu, Wanfang, and CBMdisc databases from January 1, 1990, to July 31, 2021, was performed. Articles concerning the relationship between home parenting environment and the cognitive and psychomotor development in children under 5 years old were included. Review Manager 5.4 was used for meta-analysis. Subgroup analysis in terms of age and region were performed. A total of 12 articles were included, including 11 in English and 1 in Chinese. Meta-analysis showed that there was significant relationship between home parenting environment and the cognitive and psychomotor development of children (r = 0.31; r = 0.21). Subgroup analysis showed that correlation between home parenting environment and the cognitive and psychomotor development of children was stronger in children over 18 months compared to those under 17 months [(r = 0.33, r = 0.21) vs. (r = 0.28, r = 0.17)]. The converted summary r value between home parenting environment and cognitive development in developing and developed countries was both 0.32. Conclusively, there is a positive correlation between the home parenting environment and the cognitive and psychomotor development of children under 5 years old. Improving the home parenting environment of children is beneficial to promote their early development.
