Abstract
BACKGROUND Hundreds of millions of children in low- and middle-income countries are exposed to chronic stressors, such as poverty, poor sanitation and hygiene, and sub-optimal nutrition. These stressors can have physiological consequences for children and may ultimately have detrimental effects on child development. This study explores associations between biological measures of chronic stress in early life and developmental outcomes in a large cohort of young children living in rural Bangladesh. METHODS We assessed physiologic measures of stress in the first two years of life using measures of the hypothalamic-pituitary-adrenal (HPA) axis (salivary cortisol and glucocorticoid receptor gene methylation), the sympathetic-adrenal-medullary (SAM) system (salivary alpha-amylase, heart rate, and blood pressure), and oxidative status (F2-isoprostanes). We assessed child development in the first two years of life with the MacArthur-Bates Communicative Development Inventories (CDI), the WHO gross motor milestones, and the Extended Ages and Stages Questionnaire (EASQ). We compared development outcomes of children at the 75th and 25th percentiles of stress biomarker distributions while adjusting for potential confounders using generalized additive models, which are statistical models where the outcome is predicted by a potentially non-linear function of predictor variables. RESULTS We analyzed data from 684 children (49% female) at both 14 and 28 months of age; we included an additional 765 children at 28 months of age. We detected a significant relationship between HPA axis activity and child development, where increased HPA axis activity was associated with poor development outcomes. Specifically, we found that cortisol reactivity (coefficient -0.15, 95% CI (-0.29, -0.01)) and post-stressor levels (coefficient -0.12, 95% CI (-0.24, -0.01)) were associated with CDI comprehension score, post-stressor cortisol was associated with combined EASQ score (coefficient -0.22, 95% CI (-0.41, -0.04), and overall glucocorticoid receptor methylation was associated with CDI expression score (coefficient -0.09, 95% CI (-0.17, -0.01)). We did not detect a significant relationship between SAM activity or oxidative status and child development. CONCLUSIONS Our observations reveal associations between the physiological evidence of stress in the HPA axis with developmental status in early childhood. These findings add to the existing evidence exploring the developmental consequences of early life stress.

Results We analyzed data from 684 children (49% female) at both 14 and 28 months of age; we included an additional 765 children at 28 months of age. We observed 135 primary contrasts of the differences in child development outcomes at the 75th and 25th percentiles of stress biomarkers, where we detected significant relationships in 5 out of 30 contrasts (17%) of HPA axis activity, 1 out of 30 contrasts (3%) of SAM activity, and 3 out of 75 contrasts (4%) of oxidative status. These findings revealed that measures of HPA axis activity were associated with poor development outcomes. We did not find consistent evidence that markers of SAM system activity or oxidative status were associated with developmental status. Conclusions Our observations reveal associations between the physiological evidence of stress in the HPA axis with developmental status in early childhood.

Abstract
BACKGROUND In South Asia, roughly half of women attend at least four antenatal care visits with skilled health personnel, the minimum number recommended by the World Health Organization for optimal birth outcomes. A much greater proportion of women attend at least one antenatal care visit, suggesting that a key challenge is ensuring that women initiate antenatal care early in pregnancy and continue to attend after their first visit. One critical barrier to antenatal care attendance may be that women do not have sufficient power in their relationships, households, or communities to attend antenatal care when they want to. The main goals of this paper were to 1) understand the potential effects of intervening on direct measures of women's empowerment-including household decision making, freedom of movement, and control over assets-on antenatal care attendance in a rural population of women in Bangladesh, and 2) examine whether differential associations exist across strata of socioeconomic status. METHODS We analyzed data on 1609 mothers with children under 24 months old in rural Bangladesh and employed targeted maximum likelihood estimation with ensemble machine learning to estimate population average treatment effects. RESULTS Greater women's empowerment was associated with an increased number of antenatal care visits. Specifically, among women who attended at least one antenatal care visit, having high empowerment was associated with a greater probability of ≥ 4 antenatal care visits, both in comparison to low empowerment (15.2 pp, 95% CI: 6.0, 24.4) and medium empowerment (9.1 pp, 95% CI: 2.5, 15.7). The subscales of women's empowerment driving the associations were women's decision-making power and control over assets. We found that greater women's empowerment is associated with more antenatal care visits regardless of socioeconomic status. CONCLUSIONS Empowerment-based interventions, particularly those targeting women's involvement in household decisions and/or facilitating greater control over assets, may be a valuable strategy for increasing antenatal care attendance.

Abstract
Children in low- and middle-income countries face an increased risk of impaired cognitive development due to contaminated environments, poor nutrition, and inadequate responsive stimulation from caregivers. Implementing multi-component, community-level interventions may reduce these risks; however, there is little evidence supporting implementation of these interventions at scale. We assessed the feasibility of implementing a group-based intervention that included responsive stimulation, maternal and child nutrition, water and sanitation, and childhood lead exposure prevention through the government health system in Chatmohar, Bangladesh. After implementation, we conducted 17 in-depth interviews with frontline health service providers and 12 key informant interviews with their supervisors and managers to explore the facilitators and difficulties implementing such a complex programme within the health system. Factors facilitating implementation included: high quality training and skill level of providers, support from community members, family, and supervisors, positive relationships between providers and participants, and provision of children's toys and books free of cost. Difficulties included increased workload of the providers, complicated group-based yet stage-specific delivery where providers had to manage a large group of mother-child dyads representing many different child age-groups at once, and logistics difficulties in providing toys and books through a centralised health system process. Key informants made suggestions to ensure effective government-level scale-up including engaging relevant NGOs as partners, identifying feasible ways to make toys available, and offering providers meaningful even if non-monetary rewards. These findings can be used to shape the design and delivery of multi-component child development interventions to be delivered through the health system.

Abstract
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.

Abstract
BACKGROUND Reliable and valid measurement of early child development are necessary for the design of effective interventions, programs, and policies to improve early child outcomes. One widely used measure in low- and middle-income countries (LMICs) is the Bayley Scales of Infant and Toddler Development III (Bayley-III). Alternatively, the Bangladeshi-adapted Ages and Stages Questionnaire Inventory (ASQ:I) can be administered more quickly, inexpensively, and with less training than the Bayley-III. We aimed to assess the concurrent validity of the Bangladeshi-adapted ASQ:I with the Bayley-III in children 4-27 months old in rural Bangladesh. METHODS The sample was a sub-sample (n = 244) of endline participants from an evaluation of an early child development intervention (July-August 2018). We assessed concurrent validity between internally age-standardized domain-specific and total scores using Pearson correlations both overall and stratified by age and intervention status. We also assessed correlations between scores and variables theoretically related to child development including maternal education and stimulation in the home. RESULTS The overall correlation between ASQ:I and Bayley-III total scores was moderate (r = 0.42 95% CI: 0.30-0.53), with no systematic differences by intervention status. Overall, concurrent validity was highest for the gross motor domain (r = 0.51, 0.40-0.60), and lowest for the fine motor domain (r = 0.20, 0.04-0.33). Total ASQ:I and Bayley-III scores were positively correlated with child stimulation and maternal education. CONCLUSION The Bangladeshi-adapted ASQ:I is a low-cost tool that can be feasibly administered in rural Bangladesh, is moderately correlated with the Bayley-III, and can be used to measure child development when human, time, or financial resources are constrained.

Abstract
Sustainable Development Goal 6.2 aims to end open defecation by 2030 by ensuring universal access to private household toilets. However, private toilets might not be feasible for poor households. As a result, policy makers and academics have suggested well-managed shared sanitation facilities as an alternative solution. Less is known about the associations between shared sanitation use and health. Using data from the fifth round of the National Family Health Survey from 2019 to 2021, we estimated the association between usual defecation location and child anthropometry outcomes among children under 2 years in India. The primary exposure was usual defecation location at the household level. We compared both shared improved toilet use and open defecation to private, improved toilet use. We used linear regression to estimate the associations between the exposures and linear outcomes: height-for-age Z-score, weight-for-height Z-score, and weight-for-age Z-score. We used Poisson regression with a log link to estimate the prevalence ratios of stunting, wasting, and underweight. After controlling for environmental, maternal, socioeconomic, and child confounders, we found no differences in six child anthropometry outcomes when comparing shared toilet use or open defecation to private toilet use. This finding was consistent across both urban and rural households. Our findings confirm the null associations between private toilet use and child growth found in previous studies, and that this association does not vary if the toilet is being shared. Future research should examine these differences between private and shared toilets in the context of other health outcomes.

Abstract
BACKGROUND While the prevalence of undernutrition in children has decreased in many low- and middle-income countries since the 1990s, prevalences of overweight and obesity have increased. Frequent consumption of sugar-sweetened food might have contributed to this change, although very little is known about sugar-sweetened food consumption in early life. OBJECTIVES The objective of this study was to explore the associations between individual, household, and maternal factors and the prevalence of sugar-sweetened food consumption in 6- to 24-month-old children in Bangladesh. METHODS Multistage sampling was used to select households with children aged 6-24 months in rural Chatmohar, a subdistrict of Bangladesh (n = 1635). Research assistants conducted a 24-hour qualitative dietary recall questionnaire with the enrolled child's primary caregiver to measure maternal and child dietary patterns. We examined factors associated with the prevalence of child sugar-sweetened food consumption with multivariate logistic regression models. We conducted tests of heterogeneity to explore differential associations between the child sugar-sweetened food consumption prevalence and household income by maternal nutrition knowledge and wealth. RESULTS Primary caregivers reported that 62% of toddlers had consumed sugar-sweetened food in the past 24 hours. A higher prevalence of child sugar-sweetened food consumption was associated with both a higher dietary diversity score (OR, 1.19; 95% CI, 1.09-1.29) and a higher prevalence of maternal sugar-sweetened food consumption (OR, 2.54; 95% CI, 1.97-3.28). At higher levels of maternal nutrition knowledge and wealth, more household income was associated with a lower prevalence of child sugar-sweetened food consumption. CONCLUSIONS Almost two-thirds of 6- to 24-month-old children in rural Chatmohar, Bangladesh, had consumed sugar-sweetened food in the last day. This is a high and concerning prevalence, and the associated factors identified in this study should be investigated further to identify potential areas of intervention to decrease the prevalence of child sugar consumption in Bangladesh.

Abstract
Background Since Aedes aegypti mosquitoes preferentially breed in domestic containers, control efforts focus on larval source reduction. Our objectives were to design and test the effectiveness of a source reduction intervention to improve caregiver knowledge and behaviors in coastal Kenya. Methodology/Principal findings We conducted a cluster-randomized controlled trial with 261 households from 5 control villages and 259 households from 5 intervention villages. From each household, one child (10–16 years old) and his or her primary caregiver participated in the intervention. We assessed caregiver knowledge and behavior at baseline, as well as 3 and 12 months after the intervention. We assessed household entomological indices at baseline and 12 months after the intervention to avoid seasonal interference. We conducted qualitative interviews with 34 caregivers to understand barriers and facilitators to change. We counted and weighed containers collected by children and parents during a community container clean-up and recycling event. After 12 months, caregiver knowledge about and self-reported behavior related to at least one source reduction technique was more than 50 percentage points higher in the intervention compared to control arm (adjusted risk differences for knowledge: 0.69, 95% CI [0.56 to 0.82], and behavior: 0.58 [0.43 to 0.73]). Respondents stated that other family members’ actions were the primary barriers to proper container management. The number of containers at households did not differ significantly across arms even though children and parents collected 17,200 containers (1 ton of plastics) which were used to planted 4,000 native trees as part of the community event. Conclusions/Significance Our study demonstrates that source reduction interventions can be effective if designed with an understanding of the social and entomological context. Further, source reduction is not an individual issue, but rather a social/communal issue, requiring the participation of other household and community members to be sustained. The disease burden of arboviruses transmitted by Aedes aegypti mosquitoes remains high globally. Since these mosquitoes are day-biters, bed nets are not effective at preventing mosquito bites. Additionally, because Ae. aegypti preferentially breed in domestic containers, control efforts focus on reducing containers for mosquito breeding (source reduction). We developed and evaluated a household- and school-based intervention to improve knowledge and behaviors related to source reduction. We assessed caregiver knowledge and behavior before the intervention and after 3 and 12 months. Subsequently, we conducted qualitative interviews among a sub-set of participants to understand why they did or did not change their behavior. We also assessed mosquito-related indices: the number of breeding containers and immature mosquito abundance before and 12 months after the intervention. We found that those receiving the intervention had more knowledge and self-reported behavior change than those who did not. Nonetheless, the intervention had no effect on mosquito nor containers abundance. In a multi-person household, all household members need to be committed to change, not just the caregiver and child. Our study highlights how mosquito control is not an individual issue, but one that needs the participation of a sufficient majority of household and community members to ensure effectiveness.

Abstract
Many healthcare professionals have been forced, under acute shortages, to extend medical exam gloves beyond their intended single use. Despite limited available literature, the CDC proposed a set of guidelines for repeated exam gloves use, indicating a maximum number of treatments for three widely available disinfectants. This study examines how these treatments affect the mechanical properties of latex and nitrile gloves. Furthermore, an acceptability threshold is proposed for changes in tensile property, specifically elastic modulus, as an indication of degradation. This proposed criterion was also applied to similar studies available in the literature to determine applicability and aid in recommendation development. Three different latex glove brands and three nitrile brands were exposed to repeated treatments of an alcohol-based hand rub, diluted bleach, or soap and water. Tensile tests of samples cut from untreated and treated gloves were performed to assess the change in elastic modulus induced by each treatment. The findings suggest that latex gloves performed well within the CDC recommended guidelines of six repeated treatments for an ethanol-based hand rub and 10 repeated treatments of either dilute bleach or soap and water. Nitrile exam gloves, on the other hand, showed significant changes in elastic modulus, with more inconclusive results among brands. This was especially true for treatment with dilute bleach and soap and water. Further research is needed to investigate the effects of disinfection products on the mechanical integrity of nitrile exam gloves. The results support the use of five repeated treatments of ethanol-based hand rub for nitrile exam gloves, a lower threshold than currently recommended by the CDC. This research also supports that the CDC recommendation of 10 repeated treatment with soap and water is appropriate for latex exam gloves, but not for nitrile exam gloves. Occupational safety and health professionals involved in the selection of disposable exam gloves for infection control should consider the compatibility of the glove polymer type with available disinfectants, especially if extended use with repeated disinfection becomes necessary.

Abstract
COVID-19 has created shortages of personal protective equipment. In resource-constrained situations, limited cycles of disinfection and extended use of gloves is recommended by the U.S. Centers for Disease Control and Prevention to conserve supplies. However, these guidelines are based on limited evidence. In this study, serial cycles of hand hygiene were performed on gloved hands using an ethanol-based hand rub (six and 10 cycles), 0.1% sodium hypochlorite (bleach) solution (10 cycles), or soap and water (10 cycles) on latex and nitrile medical exam gloves from the United States and India. A modified water-leak test evaluated glove integrity after repeated applications of these disinfecting agents. When aggregated, dilute bleach demonstrated the lowest difference between treatment and control arms: -2.5 percentage points (95% CI: -5.3 to 0.3) for nitrile, 0.6 percentage points (95% CI: -2.6 to 3.8) for non-powdered latex. For U.S.-purchased gloves tested with six and 10 applications of ethanol-based hand rub, the mean difference in failure risk between treatment and control gloves was within the prespecified non-inferiority margin of five percentage points or less, though some findings were inconclusive since outside the margin. The aggregated difference in failure risk between treatment and control was 3.5 percentage points (0.6 to 6.4) for soap and water, and 2.3 percentage points (-0.5 to 5.0) and 5.0 percentage points (1.8 to 8.2) for 10 and 6 applications of ethanol-based hand rub, respectively. Most leaks occurred in the interdigital webs (35%) and on the fingers (34%). This indicates that some combinations of glove types and disinfection methods may allow for extended use. Ten applications of dilute bleach solution had the least impact on glove integrity. However, the majority of glove and exposure combinations were inconclusive. Additional testing of specific glove and disinfectant combinations may inform future strategies to guide extended use during glove shortages. Additional considerations, not evaluated here, include duration of use, disinfectant chemical permeation, and the effects of hand temperature, movement, and manipulation of instruments on glove integrity.

Abstract
Early child development has been influenced directly and indirectly by the COVID‐19 pandemic, and these effects are exacerbated in contexts of poverty. This study estimates effects of the pandemic and subsequent population lockdowns on mental health, caregiving practices, and freedom of movement among female caregivers of children 6–27 months (50% female), in rural Bangladesh. A cohort (N = 517) was assessed before and during the pandemic (May–June, 2019 and July–September, 2020). Caregivers who experienced more food insecurity and financial loss during the pandemic reported larger increases in depressive symptoms (0.26 SD, 95% CI 0.08–0.44; 0.21 SD, 0.04–0.40) compared to less affected caregivers. Stimulating caregiving and freedom of movement results were inconsistent. Increases in depressive symptoms during the pandemic may have consequences for child development.

Abstract
Lead exposure is harmful at any time in life, but pre-natal and early childhood exposures are particularly detrimental to cognitive development. In Bangladesh, multiple household-level lead exposures pose risks, including turmeric adulterated with lead chromate and food storage in lead-soldered cans. We developed and evaluated an intervention to reduce lead exposure among children and their caregivers in rural Bangladesh. We conducted formative research to inform theory-based behavioral recommendations. Lead exposure was one of several topics covered in the multi-component intervention focused on early child development. Community health workers (CHWs) delivered the lead component of the intervention during group sessions with pregnant women and mother-child dyads (<15 months old) in a cluster-randomized trial. We administered household surveys at baseline (control n = 301; intervention n = 320) and 9 months later at endline (control n = 279; intervention n = 239) and calculated adjusted risk and mean differences for primary outcomes. We conducted two qualitative assessments, one after 3 months and a second after 9 months, to examine the feasibility and benefits of the intervention. At endline, the prevalence of lead awareness was 52 percentage points higher in the intervention arm compared to the control (adjusted risk difference: 0.52 [95% CI 0.46 to 0.61]). Safe turmeric consumption and food storage practices were more common in the intervention versus control arm at endline, with adjusted risk differences of 0.22 [0.10 to 0.32] and 0.13 [0.00 to 0.19], respectively. Semi-structured interviews conducted with a subset of participants after the intervention revealed that the perceived benefit of reducing lead exposure was high because of the long-term negative impacts that lead can have on child cognitive development. The study demonstrates that a group-based CHW-led intervention can effectively raise awareness about and motivate lead exposure prevention behaviors in rural Bangladesh. Future efforts should combine similar awareness-raising efforts with longer-term regulatory and structural changes to systematically and sustainably reduce lead exposure.

Abstract
Community Health Workers (CHWs) can effectively implement maternal and child health interventions, but there is paucity of evidence on how to integrate child stimulation into these interventions, and their delivery at scale. In rural Bangladesh, CHWs implemented an intervention integrating psychosocial stimulation, nutrition, maternal mental health, water, sanitation, hygiene (WASH) and lead exposure prevention. In each of 16 intervention villages, one CHW worked with 20 households. CHWs bi-weekly held group meetings or alternated group meetings and home visits with pregnant women and lactating mothers. We assessed the intervention through five focus groups, four interviews and one group discussion with CHWs and their supervisors to explore success factors of implementation. CHWs’ training, one-on-one supervision and introduction by staff to their own community, and adoption of tablet computers as job aids, enabled successful session delivery to convey behavioral recommendations. CHWs reported difficulties delivering session due to the complexity of behavioral recommendations and struggled with age-specific intervention material. Young children’s attendance in group sessions generated distractions that undermined content delivery. We identified ways to minimize the difficulties to strengthen intervention-delivery during implementation, and scale-up. Iterative revisions of similarly integrated interventions based on qualitative evaluation findings could be delivered feasibly by CHWs and allow for implementation at scale.

Abstract
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. Trial registration number The trial is registered in ISRCTN (ISRCTN16001234).

Abstract
INTRODUCTION Parenting interventions during early childhood are known to improve various child development outcomes immediately following programme implementation. However, less is known about whether these initial benefits are sustained over time. METHODS We conducted a systematic literature review of parenting interventions in low- and middle-income countries (LMICs) that were delivered during the first 3 years of life and had completed a follow-up evaluation of the intervention cohort at least 1 year after the primary postintervention endpoint. We summarized intervention effects over time by child-level and parent-level outcomes as well as by timing of follow-up rounds in the short-term (1-3 years after programme completion), medium-term (4-9 years), and long-term (10+ years). We also conducted exploratory meta-analyses to compare effects on children's cognitive and behavioral development by these subgroups of follow-up rounds. RESULTS We identified 24 articles reporting on seven randomised controlled trials of parenting interventions delivered during early childhood that had at least one follow-up study in seven LMICs. The majority of follow-up studies were in the short-term. Three trials conducted a medium-term follow-up evaluation, and only two trials conducted a long-term follow-up evaluation. Although trials consistently supported wide-ranging benefits on early child development outcomes immediately after programme completion, results revealed a general fading of effects on children's outcomes over time. Short-term effects were mixed, and medium-term and long-term effects were largely inconclusive. The exploratory meta-analysis on cognitive development found that pooled effects were significant at postintervention and in the short-term (albeit smaller in magnitude), but the effects were not significant in the medium-term and long-term. For behavioural development, the effects were consistently null over time. CONCLUSIONS There have been few longer-term follow-up studies of early parenting interventions in LMICs. Greater investments in longitudinal intervention cohorts are needed in order to gain a more comprehensive understanding of the effectiveness of parenting interventions over the life course and to improve the design of future interventions so they can have greater potential for achieving and sustaining programme benefits over time.

Abstract
Background Early childhood development (ECD) programmes can help address early disadvantages for the 43% of children younger than 5 years in low-income and middle-income countries who have compromised development. We aimed to test the effectiveness of two group-based delivery models for an integrated ECD responsive stimulation and nutrition education intervention using Kenya’s network of community health volunteers. Methods We implemented a multi-arm, cluster-randomised community effectiveness trial in three rural subcounties across 60 villages (clusters) in western Kenya. Eligible participants were mothers or female primary caregivers aged 15 years or older with children aged 6–24 months at enrolment. If married or in established relationships, fathers or male caregivers aged 18 years or older were also eligible. Villages were randomly assigned (1:1:1) to one of three groups: group-only delivery with 16 fortnightly sessions; mixed delivery combining 12 group sessions with four home visits; and a comparison group. Villages in the intervention groups were randomly assigned (1:1) to invite or not invite fathers and male caregivers to participate. Households were surveyed at baseline and immediately post-intervention. Assessors were masked. Primary outcomes were child cognitive and language development (score on the Bayley Scales of Infant Development third edition), socioemotional development (score on the Wolke scale), and parental stimulation (Home Observation for Measurement of the Environment inventory). Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT03548558. Findings Between Oct 1 and Nov 12, 2018, 1152 mother–child dyads were enrolled and randomly assigned (n=376 group-only intervention, n=400 mixed-delivery intervention, n=376 comparison group). At the 11-month endline survey (Aug 5–Oct 31, 2019), 1070 households were assessed for the primary outcomes (n=346 group only, n=373 mixed delivery, n=351 comparison). Children in group-only villages had higher cognitive (effect size 0·52 SD [95% CI 0·21–0·83]), receptive language (0·42 SD [0·08–0·77]), and socioemotional scores (0·23 SD [0·03–0·44]) than children in comparison villages at endline. Children in mixed-delivery villages had higher cognitive (0·34 SD [0·05–0·62]) and socioemotional scores (0·22 SD [0·05–0·38]) than children in comparison villages; there was no difference in language scores. Parental stimulation also improved for group-only (0·80 SD [0·49–1·11]) and mixed-delivery villages (0·77 SD [0·49–1·05]) compared with the villages in the comparison group. Including fathers in the intervention had no measurable effect on any of the primary outcomes. Interpretation Parenting interventions delivered by trained community health volunteers in mother–child groups can effectively promote child development in low-resource settings and have great potential for scalability.

Abstract
Supporting caregivers’ mental wellbeing and ability to provide psychosocial stimulation may promote early childhood development. This paper describes the systematic approach of developing an integrated stimulation intervention, identifying the feasibility and challenges faced throughout the period. We developed an integrated curriculum by culturally adapting three interventions (Reach Up, Thinking Healthy, and general nutrition advice) and piloted this curriculum (Mar–April 2017) in courtyard groups sessions and individual home visits with pregnant women (n = 11) and lactating mothers (of children <24 months) (n = 29). We conducted qualitative interviews with the participants (n = 8) and the community health workers who delivered the intervention (n = 2). Most participants reported willingness to attend the sessions if extended for 1 year, and recommended additional visual cues and interactive role-play activities to make the sessions more engaging. Participants and community health workers found it difficult to understand the concept of “unhealthy thoughts” in the curriculum. This component was then revised to include a simplified behavior-focused story. Community health workers reported difficulty balancing the required content of the integrated curriculum but were able to manage after the contents were reduced. The revised intervention is likely feasible to deliver to a group of pregnant and lactating mothers in a low-resource setting.

Abstract
BACKGROUND Despite growing evidence that early life experiences and exposures can impact child development, there is limited research on how prenatal and early life nutrition and early life parenting practices predict specific domains of child development in resource-limited settings. This study examines the association between prenatal factors, birth outcomes, and early life characteristics with motor, cognitive/language, and socioemotional development in Tanzania. METHODS We assessed motor, cognitive/language, and socioemotional development among a cohort of 198 children aged 20-39 months in Dar es Salaam, Tanzania, whose mothers were previously enrolled in a randomized, placebo-controlled trial of prenatal vitamin A and zinc supplementation. Linear regression models were used to assess standardized mean differences in child development scores for randomized prenatal regimen and pregnancy, delivery, and early childhood factors. RESULTS Children born to mothers randomized to prenatal vitamin A had significantly lower reported motor scores in minimally adjusted and multivariate analyses, -0.29 SD, 95% CI [-0.54, -0.04], p = 0.03, as compared with children whose mothers did not receive vitamin A. There was no significant effect of randomized prenatal zinc on any development domain. Greater caregiver-child stimulation was associated with 0.38 SD, 95% CI [0.14, 0.63], p < 0.01, better cognitive/language scores, whereas children who experienced both verbal and physical punishment had 0.29 SD, 95% CI [-0.52, -0.05], p = 0.02, lower scores in socioemotional development. Maternal completion of primary school was associated with higher reported motor and cognitive/language development. Further, children of mothers who were <155 cm tall had lower cognitive and language scores. CONCLUSION Prenatal vitamin A supplements in a setting with low levels of vitamin A deficiency may not provide child development benefits. However, integrated environmental, educational, parenting, and stimulation interventions may have large positive effects across child development domains in resource-limited settings.

Abstract
CONTEXT Early childhood stimulation interventions positively impact early child development (ECD) outcomes in low- and middle-income countries. However, trials have less comprehensively evaluated the effects of such parenting programs on caregivers' skills and capacities. OBJECTIVE We conducted a systematic review and meta-analysis to assess the effectiveness of stimulation interventions on improving parenting outcomes. DATA SOURCES Six electronic bibliographic databases. STUDY SELECTION Inclusion criteria included randomized controlled trials of stimulation interventions designed to improve ECD outcomes during the first 2 years of life that measured any maternal or parenting-related outcome after the start of the intervention. DATA EXTRACTION Two independent reviewers extracted data by using a structured form. RESULTS Fifteen studies representing 13 unique randomized controlled trials met the inclusion criteria. Pooled standardized mean differences (SMDs) based on random-effects models revealed medium-to-large benefits of stimulation interventions for improving the home caregiving environment (n = 10; SMD = 0.57; 95% confidence interval [CI], 0.37 to 0.77), mother-child interactions (n = 3; SMD = 0.44; 95% CI, 0.14 to 0.74), and maternal knowledge of ECD (n = 6; SMD = 0.91; 95% CI, 0.51 to 1.31). No significant difference was seen for maternal depressive symptoms (n = 9; SMD = -0.10; 95% CI, -0.23 to -0.03). LIMITATIONS Limitations include heterogeneity across interventions, lack of standardized measures, and different time points of assessments across studies. CONCLUSIONS Early childhood stimulation interventions improve several distinct aspects of maternal parenting. Improvements in parenting capacities may serve as key mechanisms by which these programs benefit ECD outcomes.
