The Effect of Birth weight on Child Development Prior to School Entry

The present study examines variation in the effect of birth weight on children’s early cognitive and socioemotional outcomes by family socioeconomic status (SES). It is hypothesized that not only will lower birth weight children display worse cognitive and socioemotional outcomes prior to school entry, as prior research has found, but that effects will be stronger for lower-SES children. Using data from the Early Childhood Longitudinal Study–Birth Cohort, the study compares the age 4 outcomes of twins discordant for birth weight (N ~ 1,400). Twin fixed-effects models are run on the full twin sample and separately for low- and high-SES children. Results support the study’s hypotheses, suggesting that socioeconomic risk accentuates the effects of birth weight on early development.     

Who Benefits Most From Head Start? Using Latent Class Moderation to Examine Differential Treatment Effects

Head Start (HS) is the largest federally funded preschool program for disadvantaged children. Research has shown relatively small impacts on cognitive and social skills; therefore, some have questioned its effectiveness. Using data from the Head Start Impact Study (3‐year‐old cohort; N = 2,449), latent class analysis was used to (a) identify subgroups of children defined by baseline characteristics of their home environment and caregiver and (b) test whether the effects of HS on cognitive, and behavioral and relationship skills over 2 years differed across subgroups. The results suggest that the effectiveness of HS varies quite substantially. For some children there appears to be a significant, and in some cases, long‐term, positive impact. For others there is little to no effect.     

Fish Oil Supplementation in Pregnancy and Neurodevelopment in Childhood—A Randomized Clinical Trial

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC₂₀₁₀ mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy supplementation affects offspring neurodevelopment until 6 years. Neurodevelopment was evaluated in 654 children assessing age of motor milestone achievement, language development, cognitive development, general neurodevelopment, and emotional and behavioral problems. Maternal n-3 LCPUFA supplementation during pregnancy improved early language development and reduced the impact of emotional and behavioral problems. The n-3 LCPUFA supplementation was in boys associated with the earlier achievement of gross motor milestones, improved cognitive development, and a reduced impact of emotional and behavioral problems.     

The impact of a vocational education program for childcare providers on children's well-being

The early childhood community-based program Hogares Comunitarios de Bienestar serves 800,000 low-income children under the age of 5 in Colombia. Earlier studies have identified care providers (madres comunitarias) as having, on average, low education levels and not being appropriately trained for the provision of childcare services. In 2007, a vocational education program was introduced which offers a degree in child development and care for childcare providers. In this paper we assess the effects of this program on the quality of care provided in the relevant nurseries and on the nutritional and health status, as well as cognitive and socio-emotional development of beneficiary children in Bogotá. This evaluation takes advantage of the gradual geographic expansion of the program in order to estimate treatment effects. Results indicate that the quality of care has significantly increased in these family-based nurseries and that the program has thus had a positive and significant effect on the health, cognitive and socio-emotional development of beneficiary children, especially those younger than 3 years of age.     

Does preschool improve child development and affect the quality of parent-child interaction? Evidence from Algeria

This paper investigates the impact of attending early childcare on the quality of parent–child interactions and children’s cognitive outcomes. Our strategy is to identify geographical differences on the basis of exposure to the program, using the period when the program was implemented across Algerian municipalities as a control for individual early childcare attendance. We estimate our results using 2SLS regression analysis and employ a difference-in-difference strategy. We use two Multiple Indicator Cluster Surveys conducted in 2006 and 2012. Our results indicate a positive correlation of preschool on the cognitive development of children. In turn, the effect is only significant given the quality of interaction between mother and children. Therefore, this finding suggests that there is a substitution effect taking place, as mothers can utilize newly acquired time relieved from childcare to accomplish other pursuits. These findings call for future research on parents’, especially mother’s, time use when their children attend early childcare.     

Impact of early intervention on expressive and receptive language development among young children with permanent hearing loss

Along with early detection, early intervention (EI) is critical for children identified with hearing loss. Evidence indicates that many children with sensorineural hearing loss experience improved language abilities if EI services were initiated at an "early" age. The present study's objectives were to determine the impact of a state EI program on language over time of children with permanent hearing loss and evaluate the association of EI enrollment by age 6 months with early language skill development. Young children in a state EI program were included in this longitudinal study. Results indicate that children enrolled prior to age 6 months were more likely to have age-appropriate language skills at baseline than children enrolled at or after 6 months, and maintained age-appropriate skills over time. Children enrolled at or after 6 months had lower baseline skills but made significant language progress, irrespective of hearing loss severity.     

Impact of the 2015 Nepal earthquakes on children’s schooling: focusing on individual children’s enrolment flow

This study examined the impact of the 2015 Nepal earthquakes on children’s schooling by focusing on individual children’s enrolment flow, particularly from public to private schools, which is becoming a worldwide trend in recent years. The results revealed that the total number of attendees at target schools recovered to pre-earthquake levels 2 months after the disaster; however, flow towards private schools was impeded, especially among ECD (early childhood development) children. The earthquake disaster sharply distinguished children who can go to a private school and those who cannot do so. Moreover, it impeded access even to public schools for children in a vulnerable position.     

Effects of Perinatal HIV Infection and Early Institutional Rearing on Physical and Cognitive Development of Children in Ukraine

To study the effects of perinatal HIV-1 infection and early institutional rearing on the physical and cognitive development of children, 64 Ukrainian uninfected and HIV-infected institutionalized and family-reared children were examined (mean age = 50.9 months). Both HIV infection and institutional care were related to delays in physical and cognitive development, with a larger effect of the rearing environment. Family care, even of compromised quality, was found to be more favorable for children's physical and cognitive development than institutional care. The impact of the quality of child care on physical and cognitive development is discussed in light of future interventions.     

Effectiveness of the Additional Early Mathematics program for teaching children early mathematics

This paper presents the results of a study of the development of early mathematical competence among young poor arithmetic achievers in the 4–7 year age group. Research has shown that arithmetic difficulties later in life can be explained by an insufficient development of early mathematical competence: i.e. different aspects of early mathematical competence. The different aspects of early mathematical competence are derived from cognitive psychology and from a didactical point of view with an emphasis on (the various phases of) counting. The Piagetian operations (seriation, correspondence and classification) are used, however, as much as possible embedded in a counting context.After selection by way of an early mathematical competence test, children with a score below a criterium are presented with an additional program. This program consists of activities, embedded in real (daily) life themes, in which attention is paid to the different aspects of early mathematical competence. The program is given to the children with a guiding or a structuring instruction form. The results of the study show that it is possible to stimulate the development of early mathematical competence among young poor arithmetic achievers. The way in which instruction is offered has no influence on achievement.     

儿童早期学习品质的本质内涵、因素结构及学习效应

近年来儿童早期学习品质受到国内外学术界的广泛关注。对61个国内外实证研究及25份新修订政策文本的分析表明,学界对儿童学习品质最基本的理解是学习品质关注的是儿童如何学习,而不是儿童学到了什么,描述的是儿童在趋近学习的过程中和投入学习时表现出来的一系列行为、认知与态度倾向;就其构成因素来说,主动性、坚持性、专注力、好奇心、创新创造、灵活性是实证研究与政策文件共同反映的高频因素;学习品质与儿童的在园学习与入学准备显著相关,且能直接预测儿童未来不同阶段的学业成就;学习品质对儿童的同伴关系、社会能力的发展也有显著影响,并能显著降低行为问题与学业困难方面的风险;学习品质在儿童的学习与发展中起着重要的调节作用,如可以调节低质量学校教育或家庭贫困对儿童学习与发展的负面影响,可以降低个体行为问题对其学业成就的不利影响等。学习品质在儿童早期学习与毕生发展中都具有重要的奠基性作用,未来应进一步探索更为低龄儿童学习品质的因素结构及其发展规律,加强我国教育背景下学习品质对儿童学习效应的实证检验与纵向追踪,探索学习品质发展的个体差异及其增长轨迹,开展相关准实验研究以进一步明确学习品质与学习效应之间的关系。不仅要促进我国儿童早期教育实践领域高度重视和践行儿童学习品质的培养,而且应在宏观政策层面把儿童学习品质的发展纳入学前教育质量评价体系,建立儿童学习品质发展数据库,实施儿童学习品质发展监测。     

How does early childhood care and education affect cognitive development? An international review of the effects of early interventions for children from different social backgrounds

A number of authors have investigated the impact of early childhood education and care programs on the development of children. Often they have focused on the effects on children from socio-economically disadvantaged families. To assess the effects of various preschool programs on cognitive development, recent key studies were reviewed. In addition, the extent to which these programs could establish equal educational opportunities for children from different social backgrounds was evaluated. Program start, intensity, and duration were considered. The findings indicate that the vast majority of recent early education and care programs had considerable positive short-term effects and somewhat smaller long-term effects on cognitive development and that in relative terms children from socio-economically disadvantaged families made as much or slightly more progress than their more advantaged peers. Despite this, early childhood education and care cannot compensate completely for developmental deficits due to unfavorable learning conditions in disadvantaged milieus. Implications for research and policy are discussed.     

A Longitudinal Study of Two Early Intervention Strategies: Project CARE

65 families with children at risk for cognitive difficulties were randomly assigned at the time of the child's birth to 1 of 3 groups, 2 intervention and 1 control. For the most intensive intervention group, family education was combined with a center-based educational day-care program; the less intensive intervention group received the home-based family education program only. To assess the cognitive performance of children, The Bayley Scales of Infant Development were administered at 6, 12, and 18 months; the Stanford-Binet Intelligence Test at 24, 36, and 48 months; and the McCarthy Scales of Children's Abilities at 30, 42, and 54 months. On each test after the 6-month assessment, scores of children in the educational day-care plus family support group were greater than those in the other 2 groups. No cognitive intervention effects were obtained for the family education group. Group effects were not obtained for measures of either the quality of the home environment or parent attention.     

Prediction of five-year Stanford-Binet scores in preterm infants

The development of a group of 100 preterm infants, mean birth weight 1,877 grams, from a broad range of social class and ethnic backgrounds was followed from birth to age 5. Assessments in infancy were directed at medical problems and early perceptual, motor, social, and cognitive development. The child's performance on the Stanford-Binet test at age 5 could not be predicted from early hazardous events in the obstetrical or neonatal period. The results indicate that developmental outcome at age 5 could be predicted moderately from a single measure, infant visual attention, administered as early as term date. Prediction was improved by using a combination of assessments given during the first 9 months. Furthermore, prediction was significantly better for girls than for boys. Although moderate stability in performance was found for the group as a whole, prediction of an individual's performance resulted in a substantial number of children being misclassified. Social factors were more important than any other set of factors in relating to the child's mental performance at age 5.     

Child Maltreatment and Children's Developmental Trajectories in Early to Middle Childhood

Associations between experiencing child maltreatment and adverse developmental outcomes are widely studied, yet conclusions regarding the extent to which effects are bidirectional, and whether they are likely causal, remain elusive. This study uses the Fragile Families and Child Wellbeing Study, a birth cohort of 4,898 children followed from birth through age 9. Hierarchical linear modeling and structural equation modeling are employed to estimate associations of maltreatment with cognitive and social‐emotional well‐being. Results suggest that effects of early childhood maltreatment emerge immediately, though developmental outcomes are also affected by newly occurring maltreatment over time. Additionally, findings indicate that children's early developmental scores predict their subsequent probability of experiencing maltreatment, though to a lesser extent than early maltreatment predicts subsequent developmental outcomes.     

Research priority setting for integrated early child development and violence prevention (ECD+) in low and middle income countries: An expert opinion exercise

Child development in low and middle income countries (LMIC) is compromised by multiple risk factors. Reducing children’s exposure to harmful events is essential for early childhood development (ECD). In particular, preventing violence against children – a highly prevalent risk factor that negatively affects optimal child development – should be an intervention priority. We used the Child Health and Nutrition Initiative (CHNRI) method for the setting of research priorities in integrated Early Childhood Development and violence prevention programs (ECD+). An expert group was identified and invited to systematically list and score research questions. A total of 186 stakeholders were asked to contribute five research questions each, and contributions were received from 81 respondents. These were subsequently evaluated using a set of five criteria: answerability; effectiveness; feasibility and/or affordability; applicability and impact; and equity. Of the 400 questions generated, a composite group of 50 were scored by 55 respondents. The highest scoring research questions related to the training of Community Health Workers (CHW’s) to deliver ECD+ interventions effectively and whether ECD+ interventions could be integrated within existing delivery platforms such as HIV, nutrition or mental health platforms. The priority research questions can direct new research initiatives, mainly in focusing on the effectiveness of an ECD+ approach, as well as on service delivery questions. To the best of our knowledge, this is the first systematic exercise of its kind in the field of ECD+. The findings from this research priority setting exercise can help guide donors and other development actors towards funding priorities for important future research related to ECD and violence prevention.

Patterns of Early‐Life Social and Environmental Exposures and Child Cognitive Development,Rhea Birth Cohort,Crete, Greece

Early‐life exposures are critical for later child cognitive development. McCarthy Scales of Children's Abilities (MSCA) were used to assess cognitive development of 700 preschoolers (M_age = 4.2 years), derived from the “Rhea” birth cohort, in Greece. Principal component analysis (PCA) was applied on prospectively collected exposure data. Six components were extracted; five of them were associated with child cognition. Higher parental social status, preschool attendance and less TV watching, nonsmoking during pregnancy and breastfeeding, and parental involvement in child life were protective factors of child cognition at 4 years. Increased child birth order was negatively associated with child cognition. Offspring's size at birth was not associated with any cognitive outcome. These findings reveal the importance of early‐life exposures to child cognitive development.

Marital birth and early child outcomes: the moderating influence of marriage propensity

Using data from the Fragile Families and Child Well-Being Study, the present study tested whether the benefits of a marital birth for early child development diminish as parents' risk of having a nonmarital birth increases (N = 2,285). It was hypothesized that a child's likelihood of being born to unmarried parents is partly a function of father characteristics that predict his capacity to promote child development. Results partially supported hypothesis. A positive association emerged between parental marriage and cognitive outcomes at age 3 only for children whose parents were likely to be married at the child's birth, suggesting average differences between children in married and unmarried families may overestimate the benefit of marriage in subpopulations most impacted by nonmarital birth.     

Pathsways to school achievement in very preterm and full term children

Individual differences in academic success were investigated in a geographically defined whole-population sample of very preterm children with a gestational age of less than 32 weeks or a birth weight of less than 1500 gm. The sample consisted of 264 very preterm children (75.6% of German-speaking survivors) and 264 controls matched for gender, socioeconomic status, marital status and age of mother, who were studied from birth. The present analyses focused on the impact of cognitive skills assessed at ages 6 and 8 on academic success at the age 13. IQ scores, prereading skills, reading, spelling, and math performance assessed during the last kindergarten year and again at the end of Grade 2 were used as predictors of academic success in early adolescence. Differences between very pretern children and controls in cognitive abilities already observed in earlier assessments remained stable over time, with controls on average performing more than half a standard deviation above the level of preterm children. Preterm children also performed poorer on the literacy measures and indicators of math performance. Multivariate and causal modeling revealed different prediction patterns for the two groups. Whereas IQ was particularly important for the prediction of academic success in the pre-term sample, general IQ was less relevant for the prediction of academic success in the control group. When subgroups of at-risk children were formed according to birth weight categories, we found that school problems were most pronounced for children with extremely low birth weight (1000 gm and less).
