Abstract
OBJECTIVE Low birth weight (LBW) infants are at increased risk of cognitive and behavioral problems and at risk for iron deficiency, which is associated with impaired neurodevelopment. We hypothesized that iron supplementation of LBW infants would improve cognitive scores and reduce behavioral problems. METHODS In a randomized controlled trial, 285 marginally LBW (2000-2500 g) infants received 0, 1, or 2 mg/kg/day of iron supplements from 6 weeks to 6 months of age. At 3.5 years of age, these infants and 95 normal birth weight controls were assessed with a psychometric test (Wechsler Preschool and Primary Scale of Intelligence) and a questionnaire of behavioral problems (Child Behavior Checklist; CBCL). RESULTS There were no significant differences in IQ between the LBW groups or LBW infants versus controls. Mean (SD) full-scale IQ was 105.2 (14.5), 104.2 (14.7), and 104.5 (12.7) in the placebo, 1 mg, and 2 mg groups, respectively (P = .924). However, for behavioral problems, there was a significant effect of intervention. The prevalence of children with CBCL scores above the US subclinical cutoff was 12.7%, 2.9%, and 2.7% in the placebo, 1-mg, and 2-mg groups, respectively (P = .027), compared with 3.2% in controls. Relative risk (95% confidence interval) for CBCL score above cutoff in placebo-treated children versus supplemented was 4.5 (1.4-14.2). CONCLUSIONS Early iron supplementation of marginally LBW infants does not affect cognitive functions at 3.5 years of age but significantly reduces the prevalence of behavioral problems. The study suggests a causal relation between infant iron deficiency and later behavioral problems.

Abstract
Hypotheses regarding the developmental origins of health and disease postulate that developing fetuses - and potentially young children - undergo adaptive epigenetic changes that have longstanding effects on metabolism and other processes. Ongoing research explores whether these adaptations occur during early life following early childhood malnutrition. In the developing world, there remains a high degree of nutritional stunting, defined as linear growth failure caused by inadequate caloric intake, which may be exacerbated by inflammation from ongoing infections. In areas with poor sanitation, children experience vicious cycles of enteric infections and malnutrition, resulting in poor nutrient absorption as a result of changes in the intestinal mucosa, now termed "environmental enteropathy." Emerging evidence links early childhood diarrhea and/or growth failure with an increased occurrence of risk factors for cardiovascular disease in later life, including dyslipidemia, hypertension, and glucose intolerance. The mechanisms for these associations remain poorly understood and may relate to epigenetic responses to poor nutrition, increased inflammation, or both. Given the increased incidence of cardiovascular disease in developing areas of the world, associations between childhood malnutrition, early-life infections, and the increased occurrence of risk factors for cardiovascular disease underscore further reasons to improve nutrition and infection-related outcomes for young children worldwide.

Abstract
PURPOSE To investigate the effects of socioeconomic changes from birth to 11 years of life on emotional, conduct, and attentional/hyperactivity problems in 15-year-old adolescents, from the 1993 Pelotas (Brazil) birth cohort study. METHODS The original cohort was composed of 5,249 hospital-born children whose mothers answered a questionnaire. We conducted interviews with 87.5% and 85.7% of the original cohort in 2004-2005 and 2008, respectively. We divided family income changes into nine possible categories based on two assessment points (birth and 11 years of age) and three income levels. To assess the psychopathology of the adolescents at 15 years of age, 4,423 mothers answered the Strengths and Difficulties Questionnaire. RESULTS Adolescents who were always poor or who became poor between birth and 11 years of age had greater conduct problems at 15 years of age. There was no consistent association between poverty and emotional and attentional/hyperactivity problems. CONCLUSIONS The effects of income change were more specific to conduct problems than to emotional and attentional/hyperactivity problems, similar to what has been previously described in developed countries.

Abstract
Gradients across socio-economic position exist for many measures of children's health and development in higher-income countries. These associations may not be consistent, however, among the millions of children living in lower- and middle-income countries. Our objective was to examine child development and growth in young children across socio-economic position in four developing countries. We used cross-sectional surveys, child development assessments, measures of length (LAZ), and home stimulation (Family Care Index) of children in India, Indonesia, Peru, and Senegal. The Extended Ages and Stages Questionnaire (EASQ) was administered to parents of all children ages 3-23 mo in the household (n =8,727), and length measurements were taken for all children 0-23 mo (n = 11,102). Household wealth and maternal education contributed significantly and independently to the variance in EASQ and LAZ scores in all countries, while controlling for child's age and sex, mother's age and marital status, and household size. Being in the fifth wealth quintile in comparison with the first quintile was associated with significantly higher EASQ scores (0.27 to 0.48 of a standardized score) and higher LAZ scores (0.37 to 0.65 of a standardized score) in each country, while controlling for maternal education and covariates. Wealth and education gradients increased over the first two years in most countries for both EASQ and LAZ scores, with larger gradients seen in 16-23-mo-olds than in 0-7 mo-olds. Mediation analyses revealed that parental home stimulation activities and LAZ were significant mediating variables and explained up to 50% of the wealth effects on the EASQ.

Abstract
Extensive evidence that personal experiences and environmental exposures are embedded biologically (for better or for worse) and the cumulative knowledge of more than four decades of intervention research provide a promising opportunity to mobilize evolving scientific insights to catalyze a new era of more effective early childhood policy and practice. Drawing on emerging hypotheses about causal mechanisms that link early adversity with lifelong impairments in learning, behavior, and health, this paper proposes an enhanced theory of change to promote better outcomes for vulnerable, young children by strengthening caregiver and community capacities to reduce or mitigate the impacts of toxic stress, rather than simply providing developmental enrichment for the children and parenting education for their mothers.

Abstract
A principle strategic insight of the Final Report for WHO’s Commission on Social Determinants of Health (SDOH) is that the nurturant qualities of the environments where children grow up, live, and learn matter the most for their development. A key determinant of early childhood development is the establishment of a secure attachment between a caregiver and child. We report initial field-tests of the integration of caregiver-child attachment assessment by community health workers (CHWs) as a routine component of Primary Health Care (PHC), focusing on households with children under 5 years of age in three slum communities near Nairobi, Kenya. Of the 2,560 children assessed from July–December 2010, 2,391 (90.2%) were assessed as having a secure attachment with a parent or other caregiver, while 259 (9.8%) were assessed as being at risk for having an insecure attachment. Parent workshops were provided as a primary intervention, with re-enforcement of teachings by CHWs on subsequent home visits. Reassessment of attachment by CHWs showed positive changes. Assessment of caregiver-child attachment in the setting of routine home visits by CHWs in a community-based PHC context is feasible and may yield valuable insights into household-level risks, a critical step for understanding and addressing the SDOH.

Abstract
OBJECTIVE Chile is considering expanding its system for early childhood development to include 5- to 7-year olds, but it has no consensus about how to identify at-risk children. This study facilitated a process for incorporating local priorities and best practices to choose a child assessment instrument. METHODS Using the priority-setting method of the Child Health and Nutrition Research Initiative (CHNRI), 21 Chilean experts defined and weighted ideal assessment instrument characteristics; 130 instruments were scored according to how closely they matched experts' ideal definitions. Instruments were ranked by score under different inclusion criteria. RESULTS Experts weighted instrument quality highest (95 on 1-100 scale), followed by administration site (87), domains assessed (82), cost (80), administrator (76), Spanish version (75), time (75), and prior use in Chile (53). Experts agreed that an ideal instrument (1) would reliably assess language, socioemotional well-being, mental health, and parenting abilities, (2) could be administered at schools or home, and (3) could be administered by teachers or parents. No single instrument matched all Chilean priorities. Three instruments met 11 of 13 priorities (age; quality; administration at school, home, or waiting rooms; assess language and socioemotional domains; administered by teachers, parents, or psychologists; time ≤30 minutes). Including mental health or parenting abilities ranked instruments whose composite scores were 35% lower. CONCLUSION Decisions about how to assess children at developmental risk should be informed by local context. The CHNRI method provided a useful process that made explicit mutually exclusive priorities, quantified trade-offs of different assessment strategies, and identified 3 of the instruments that best met local needs and priorities.

Abstract
BACKGROUND There is increasing recognition that perinatal common mental disorders (PCMDs) are prevalent in women in low and lower-middle income countries and emerging evidence that PCMDs and alcohol abuse occur in men in these settings. Domestic violence is associated with PCMDs in both women and men. The aim of this study was to examine the relationships among PCMDs, alcohol abuse and domestic violence in couples in a rural, low-income setting. METHODS A cross-sectional, population-based study was undertaken in randomly selected communes in Ha Nam and Hanoi, Vietnam. All women in the selected study sites who were at least 28 weeks pregnant or were mothers of 4 - 6 week old babies in the recruitment period were eligible. The husbands of the women who consented to join the study were also invited to participate. Data sources were study-specific questions and standardised measures: PCMDs were assessed by psychiatrist-administered Structured Clinical Interviews for DSM IV disorders, and alcohol dependence (AD) by the CAGE questionnaire (cut-off of ≥ 2). Structural Equation Modeling was used to test direct, indirect and mutual relationships simultaneously in the hypothesised model. RESULTS In total 364/392 (93%) eligible women agreed to participate. Of these, 360 were married, and 230 (64%) of their husbands also participated to yield a sample of 230 couples for analyses. Overall, in 7.4% (95% CI: 4.6-11.6) of couples both wife and husband were diagnosed with a PCMD; and 41.2% (95% CI: 35.1-47.8) of couples at least one member had a PCMD. Comorbid PCMD and AD were observed in 6.9% (95% CI: 4.3-11.0) of men, but did not occur in women. After controlling for other psychosocial risk factors comorbid PCMD and AD in husbands increased by 4.7 times the probability of PCMDS in their wives via intimate partner violence. PCMDS in wives did not increase the probability of PCMDS or AD in husbands. CONCLUSIONS These data provide evidence that comorbid PCMD and AD in husbands have a significant adverse effect on the mental health of their wives in rural areas of Vietnam. This indicates that strategies to prevent and treat PCMDs in women will be more effective if paired with initiatives to reduce alcohol dependence and violent behaviours in men.

Abstract
We examined the long-term direct and indirect links between coparenting (conflict, communication, and shared decision-making) and preschoolers' school readiness (math, literacy, and social skills). The study sample consisted of 5,650 children and their biological mothers and fathers who participated in the Early Childhood Longitudinal Study-Birth Cohort. Using structural equation modeling and controlling for background characteristics, we found that our conceptual model of the pathways from coparenting to child outcomes is structurally the same for cohabiting and married families. Controlling for a host of background characteristics, we found that coparenting conflict and shared decision-making were negatively and positively, respectively, linked to children's academic and social skills and co-parental communication was indirectly linked to academic and social skills through maternal supportiveness. Coparenting conflict was also indirectly linked to children's social skills through maternal depressive symptoms. The overall findings suggest that for both cohabiting and married families, the context of conflicted coparenting may interfere with the development of children's social competencies and academic skills, whereas collaborative coparenting promotes children's school readiness because mothers are more responsive to their children's needs. These findings have implications for programs aimed at promoting positive family processes in cohabiting and married families.

Abstract
Although the study of brain development in non-human animals is an old one, recent imaging methods have allowed non-invasive studies of the gray and white matter of the human brain over the lifespan. Classic animal studies show clearly that impoverished environments reduce cortical gray matter in relation to complex environments and cognitive and imaging studies in humans suggest which networks may be most influenced by poverty. Studies have been clear in showing the plasticity of many brain systems, but whether sensitivity to learning differs over the lifespan and for which networks is still unclear. A major task for current research is a successful integration of these methods to understand how development and learning shape the neural networks underlying achievements in literacy, numeracy, and attention. This paper seeks to foster further integration by reviewing the current state of knowledge relating brain changes to behavior and indicating possible future directions.

Two out of three children diagnosed with conduct disorder will not outgrow it without treatment. It is costly to the individual in terms of negative life outcomes and to society in terms of increased health, social and education service use. Psychosocial interventions are effective in psychologically managing and preventing the onset of conduct disorder.

Abstract
BACKGROUND The Baby-Friendly Hospital Initiative (BFHI), developed by the World Health Organization and the United Nations Children's Fund (UNICEF) to promote breastfeeding in maternity facilities worldwide, has had a global impact on breastfeeding outcomes, but other interventions are needed both before and after hospital discharge to meet the recommended targets at 6 months. The Baby-Friendly Community Initiative (BFCI), a multifaceted program for community-based breastfeeding promotion that is complementary to the BFHI, addresses this challenge. OBJECTIVE To describe the development, strategy, and implementation of the BFCI in Italy. METHODS In 2006, UNICEF Italy created a working group to develop the BFCI for the Italian health system. A review of the different BFCI models worldwide was conducted. A preliminary adaptation of tools to Italian community health care settings was developed in 2007, when the Italian BFCI Seven Steps were published. Two years later, UNICEF Italy launched the Standards for Best Practice for both hospitals and communities, based on 2009 BFHI and UNICEF UK BFCI materials. OUTCOMES The main outcome was to promote this process in Italian regional health systems and develop tools to assess compliance with the BFCI criteria. There is now one fully accredited Baby-Friendly Community in Italy, and 17 other communities are working on the various stages. CONCLUSIONS The BFCI, a complex program that involves participation, training, audits, a continuous flow of feedback, and provision of resources for health workers and families, is now a reality in Italy.

Abstract
Reviews of programmes in Bangladesh, Benin, the Philippines, Sri Lanka, Uganda, and Uzbekistan sought to identify health policy and programmatic factors that influenced breastfeeding practices during a 10 to 15 year period. Exclusive breastfeeding rates and trends were analysed in six countries in general and from an equity perspective in two of them. Success factors and challenges were identified in countries with improved and stagnated rates respectively. The disaggregated data analysis showed that progress may be unequal in population subgroups, but if appropriately designed and implemented, a programme can become a "health equalizer" and eliminate discrepancies among different subgroups. Success requires commitment, supportive policies, and comprehensiveness of programmes for breastfeeding promotion, protection and support. Community-based promotion and support was identified as a particularly important component. Although health workers' training on infant feeding support and counselling was prioritized, further improvement of interpersonal counselling and problem solving skills is needed. More attention is advised for pre-service education, including a stronger focus on clinical practice, to ensure knowledge and skills among all health workers. Large-scale communication activities played a significant role, but essential steps were often underemphasized, including identifying social norms and influencing factors, ensuring community participation, and testing of approaches and messages.

Abstract
We used structural MRI and EEG to examine brain structure and function in typically developing children in Romania (n = 20), children exposed to institutional rearing (n = 29), and children previously exposed to institutional rearing but then randomized to a high-quality foster care intervention (n = 25). In so doing, we provide a unique evaluation of whether placement in an improved environment mitigates the effects of institutional rearing on neural structure, using data from the only existing randomized controlled trial of foster care for institutionalized children. Children enrolled in the Bucharest Early Intervention Project underwent a T1-weighted MRI protocol. Children with histories of institutional rearing had significantly smaller cortical gray matter volume than never-institutionalized children. Cortical white matter was no different for children placed in foster care than never-institutionalized children but was significantly smaller for children not randomized to foster care. We were also able to explain previously reported reductions in EEG α-power among institutionally reared children compared with children raised in families using these MRI data. As hypothesized, the association between institutionalization and EEG α-power was partially mediated by cortical white matter volume for children not randomized to foster care. The increase in white matter among children randomized to an improved rearing environment relative to children who remained in institutional care suggests the potential for developmental "catch up" in white matter growth, even following extreme environmental deprivation.

Abstract
The Multiple Indicator Cluster Survey was used to provide information on feeding practices, caregiving, discipline and violence, and the home environment for young children across 28 countries. The findings from the series of studies in this Special Section are the first of their kind because they provide information on the most proximal context for development of the youngest children in the majority world using one of the only data sets to study these contexts across countries. Using the framework of the Convention on the Rights of the Child, in particular the Rights to Survival, Development and Protection, findings are explained with implications for international and national-level social policies. Implications are also discussed, with respect to policy makers and the larger international community, who have the obligation to uphold these rights.

Abstract
Research from numerous fields of science has documented the critical importance of nurturing environments in shaping young children's future health and development. We studied the environments of early childhood (birth to 3 years) during postconflict, postdisplacement transition in northern Uganda. The aim was to better understand perceived needs and risks in order to recommend targeted policy and interventions. Methods. Applied ethnography (interview, focus group discussion, case study, observational methods, document review) in 3 sites over 1 year. Results. Transition was a prolonged and deeply challenging phase for families. Young children were exposed to a myriad of risk factors. Participants recognized risks as potential barriers to positive long-term life outcomes for children and society but circumstances generally rendered them unable to make substantive changes. Conclusions. Support structures were inadequate to protect the health and development of children during the transitional period placing infants and young children at risk. Specific policy and practice guidelines are required that focus on protecting hard-to-reach, vulnerable, children during what can be prolonged and extremely difficult periods of transition.

Abstract
OBJECTIVES Perinatal depression has been found to be a strong and independent risk factor for poor child growth and development in low-income South Asian populations. The authors aimed to study if there was a similar association in first and second-generation British women of Pakistani origin. DESIGN A prospective cohort study. SETTING The study was conducted in the North-West of England, in areas with high density of Pakistani-origin population. The subjects were recruited from Central Manchester Hospital in the City of Manchester and East Lancashire Hospital in Lancashire. PARTICIPANTS 704 physically healthy women were assessed in two phases (screening and detailed assessment of high scorers and a proportion of low scorers) during the third trimester of pregnancy to obtain at birth a cohort of 63 infants of depressed mothers and 173 infants of psychologically well mothers. PRIMARY AND SECONDARY OUTCOME MEASURES All infants were weighed and measured at birth and 6 months, and their development was assessed using the Bayley Scales of Infant Development-Third Edition. RESULTS There was no difference in the birth weight or weight and height at 6 months of infants of depressed mothers versus infants of psychologically well mothers. The only significant difference between the two groups was in the infants' adaptive behaviour; infants of depressed mothers scored significantly lower than those of psychologically well mothers (mean difference 4.6, t=2.81, df 195, p=0.006). The associations remained significant after adjustment for socio-demographic factors by multivariate analyses. CONCLUSIONS Prenatal depression is not associated with impaired growth in this sample of British Pakistani women. There is, however, an association of prenatal depression with parent-reported problems in the infants' adaptive behaviour. Further research is needed to understand various pathways through which maternal depression affects infant outcomes in low- and high-income settings.

Abstract
This report is the second in a Series on early child development in low-income and middle-income countries and assesses the effectiveness of early child development interventions, such as parenting support and preschool enrolment. The evidence reviewed suggests that early child development can be improved through these interventions, with effects greater for programmes of higher quality and for the most vulnerable children. Other promising interventions for the promotion of early child development include children's educational media, interventions with children at high risk, and combining the promotion of early child development with conditional cash transfer programmes. Effective investments in early child development have the potential to reduce inequalities perpetuated by poverty, poor nutrition, and restricted learning opportunities. A simulation model of the potential long-term economic effects of increasing preschool enrolment to 25% or 50% in every low-income and middle-income country showed a benefit-to-cost ratio ranging from 6·4 to 17·6, depending on preschool enrolment rate and discount rate.
