Introduction Paediatric acquired brain injury (ABI) causes cognitive and behavioural difficulties and alters the course of child development. The ABI unit at Hospital Infantil Universitario Nino Jesus is the first within the public Spanish health system to provide comprehensive coverage to these patients and their families. Objective This study aims to show the working methodology followed with patients and their families, and to describe the clinical characteristics of the patients treated and the outcomes of treatment. Patients Fifty-three patients aged between three months and 16 and a half years received treatment. The conditions treated were brain tumours, stroke, traumatic brain injury, damage secondary to epilepsy surgery, and hypoxia. Methods All patients were evaluated at admission and at discharge. Treatments were adapted to each patient's difficulties and their severity, as well as to the patient's age. Families received individual and group therapy. Results Older age was associated with better cognitive recovery and shorter duration of treatment. Different conditions show differential impact on intelligence quotient and developmental quotient scores at the beginning of treatment, with hypoxia and encephalitis being associated with greatest severity. Intelligence quotient and developmental quotient scores and visual memory and attention scores at discharge improved significantly after the faceted neuropsychological treatment with respect to scores registered at admission. Conclusions The care of patients with ABI should include neuropsychological rehabilitation programmes and provide emotional support to the family so that they may actively participate in the recovery of the child or adolescent.

Shared picture-book reading is well-recognized as beneficial for children’s early language development, especially where ‘dialogic book-sharing’ techniques are used. Possible benefits of dialogic book-sharing to other aspects of child development have been little investigated, and it has not been widely studied in European populations. We conducted a randomized trial of dialogic book-sharing in Children’s Centers in the UK, with parents of 2-4-year-old children, hypothesizing that it would benefit parenting and a range of child developmental outcomes.\ud Intervention group parents (n = 110) received seven, weekly, group training sessions and control parents (n = 108) the usual center input. Parenting and a range of child outcomes (language, attention, executive function, social development and emotional-behavior difficulties) were assessed on three occasions: before, after, and 4-6 month following intervention. For all study outcomes we compared controls with each of the Intention-to-Treat population and the perprotocol population (participants attending the requisite number of sessions); and, for primary child outcomes only, the population of parents who engaged well with the intervention. There were substantial benefits of dialogic book-sharing training to parental behavior during booksharing, especially for sensitivity and cognitive scaffolding. For all three sets of comparisons there were small-medium effects of on child expressive language, and, for the per protocol and engaged populations, similar sized effects on child receptive language and attention. There was no evidence of benefit of dialogic book-sharing for the other areas of child development; we suggest that specific intervention components need to be added to standard dialogic book-sharing to effect change in these areas.

Infants who undergo surgery for congenital heart disease are at risk of neurodevelopmental delay. Cardiac surgery-associated acute kidney injury (CS-AKI) is common but its association with neurodevelopment has not been explored.This was a single-center retrospective observational study of infants who underwent cardiac surgery in the first year of life who had neurodevelopmental testing using the Bayley Scale for Infant Development, third edition. Single and recurrent episodes of stages 2 and 3 CS-AKI were determined.Of 203 children with median age at first surgery of 12 days, 31% had one or more episodes of severe CS-AKI; of those, 16% had recurrent CS-AKI. Median age at neurodevelopmental assessment was 20 months. The incidence of delay was similar for patients with and patients without CS-AKI but all children with recurrent CS-AKI had a delay in one or more domains and had significantly lower scores in all three domains, namely, cognitive, language, and motor.This study has assessed the association of CS-AKI with neurodevelopmental delay after surgery for congenital heart disease in infancy. Infants who have recurrent CS-AKI in the first year of life are more likely to be delayed and have lower neurodevelopmental scores.

This study investigated developmental trajectories of observationally coded engagement across the early elementary years and whether these trajectories were associated with children's academic achievement. Furthermore, we evaluated if these relations varied as a function of children's family socio-economic status and early reading and math skills. Data were collected from 301 children who were studied from kindergarten (M

Children born very preterm (≤32 weeks gestational age) show poorer cognitive and language development compared with their term-born peers. The importance of supportive maternal responses to the child's cues for promoting neurodevelopment is well established. However, little is known about whether supportive maternal behavior can buffer the association of early brain dysmaturation with cognitive and language performance.Infants born very preterm (N = 226) were recruited from the neonatal intensive care unit for a prospective, observational cohort study. Chart review (e.g., size at birth, postnatal infection) was conducted from birth to discharge. Magnetic resonance imaging, including diffusion tensor imaging, was acquired at approximately 32 weeks postmenstrual age and again at term-equivalent age. Fractional anisotropy, a quantitative measure of brain maturation, was obtained from 11 bilateral regions of interest in the cortical gray matter. At 3 years (n = 187), neurodevelopmental testing (Bayley Scales of Infant and Toddler Development-III) was administered, and parent-child interaction was filmed. Maternal behavior was scored using the Emotional Availability Scale-IV. A total of 146 infants with neonatal brain imaging and follow-up data were included for analysis. Generalized estimating equations were used to examine whether maternal support interacted with mean fractional anisotropy values to predict Cognitive and Language scores at 3 years, accounting for confounding neonatal and maternal factors.Higher maternal support significantly moderated cortical fractional anisotropy values at term-equivalent age to predict higher Cognitive (interaction term β = 2.01, p = .05) and Language (interaction term β = 1.85, p = .04) scores.Findings suggest that supportive maternal behavior following early brain dysmaturation may provide an opportunity to promote optimal neurodevelopment in children born very preterm.

To identify perinatal antecedents associated with neurodevelopmental impairment for very low birth weight (VLBW) preterm infants at ages 6, 12, and 24 months and the stability of neurodevelopmental assessments.A multicenter-based VLBW cohort was recruited, and the mental development index (MDI) and psychomotor development index (PDI) were used to evaluate children's neurodevelopment stages at ages 6, 12, and 24 months. Perinatal risk factors were determined through univariate and multivariate hierarchical linear analyses. Differences and predictability in MDI or PDI scores between ages 6 and 24 months were assessed.Covariates including father's education level; teenage pregnancy, multiple pregnancies; infant's gestational age, gender, and birth weight999 gm, duration of neonatal intensive care unit stay; and presence of various diseases were adversely associated with poor MDI or PDI scores in 8517 eligible VLBW infants during the study period. Polyhydramnios, emergency cesarean delivery, birth weight of1250 gm, and periventricular/intraventricular hemorrhage stage I-II were additional risk factors of VLBW infants with an adverse PDI score. An increased number of infants with a MDI or PDI score of55 at age 24 months was observed. Six-month MDI or PDI assessments had a low ability to predict outcomes at 24 months, with sensitivity and positive predictive values under 60% and specificity and negative predictive values over 85%.Multiple perinatal risk factors are associated with poor MDI and PDI scores among VLBW preterm infants. Six-month developmental assessments exhibited low sensitivity and positive predictive values for outcomes at 24 months.

BACKGROUND: There is emerging evidence that exposure to prenatal methylmercury (MeHg) from maternal fish consumption during pregnancy can differ between individuals due to genetic variation. In previous studies, we have reported that maternal polymorphisms in ABC-transporter genes were associated with maternal hair MeHg concentrations, and with children’s early neurodevelopmental tests. In this study, we add to these findings by evaluating the contribution of genetic variation in children’s ABC-transporter genes to prenatal MeHg exposure and early child neurodevelopmental tests. METHODS: We genotyped six polymorphisms (rs2032582, rs10276499 and rs1202169 in ABCB1; rs11075290 and rs215088 in ABCC1; rs717620 in ABCC2) in DNA from cord blood and maternal blood of the Seychelles Child Development Study Nutrition Cohort 2. We determined prenatal MeHg exposure by measuring total mercury (Hg) in cord blood by atomic fluorescence spectrometry. We assessed neurodevelopment in children at approximately 20 months using the Bayley Scales of Infant Development (BSID-II). We used linear regression models to analyze covariate-adjusted associations of child genotype with cord MeHg and BSID-II outcomes (Mental Developmental and Psychomotor Developmental Indexes). We also evaluated interactions between genotypes, cord MeHg, and neurodevelopmental outcomes. All models were run with and without adjustment for maternal genotype. RESULTS: Of the six evaluated polymorphisms, only ABCC1 rs11075290 was associated with cord blood MeHg; children homozygous for the T-allele had on average 29.99 μg/L MeHg in cord blood while those homozygous for the C-allele had on average 38.06 μg/L MeHg in cord blood (p

Bisphenol A (BPA) is a polymer used in the production of polycarbonate plastics and epoxy resins. An estrogen mimic, prenatal BPA exposure has been associated with several behavioral outcomes in children; however, the impact of maternal demographic and economic factors on associations between BPA and child behavioral outcomes have not been examined. The objective of this study was to examine associations between prenatal maternal urinary BPA and behavior in 4-5 year old girls, and to assess whether socio-demographic factors modify this relationship. Mothers enrolled in The Infant Development and Environment Study (TIDES) provided a single spot urine at enrollment (median gestational age 11 weeks) and completed the Behavior Assessment System for Children-2 (BASC-2) and Social Responsiveness Scale-2 (SRS-2) when their daughters were 4-5 years of age. Mother-daughter pairs with complete phthalate, BASC-2, SRS-2, and covariate data were included in this analysis (N=244). BPA was detectable in 93 % of urine samples. We used multivariable linear regression analyses to estimate associations between maternal urinary log10-transformed BPA concentration and BASC-2 subscale and composite scores and SRS-2 Total Score. To examine the role of socioeconomic and demographic factors associated with study site, we stratified by TIDES center, comparing those enrolled at University of Rochester Medical Center (URMC), a predominately lower socioeconomic population, and those enrolled elsewhere: University of Washington, University of Minnesota, and University of California San Francisco, whose populations share similar higher socioeconomic demographic characteristics. Across all centers, no associations were seen between BPA and BASC-2 or SRS-2 scores. When stratifying by center, BPA was significantly associated with greater social impairment as measured by the SRS-2 Total Score (β-coefficient [95 % confidence intervals]: 5.1 [1.0, 9.2]) in URMC participants (N=61). In non-URMC participants (N=183), BPA was significantly associated with lower BASC-2 Internalizing composite (-3.3 [-6.7, 0.0]) and Depression subscale scores (-3.4 [-6.7, 0.0]) while no associations were seen between BPA and SRS-2 scores. Our findings suggest that sociodemographic factors may modify the impacts of maternal prenatal BPA on developmental endpoints.

Wealth, power, and status are distributed unevenly across social groups. A surge of recent research reveals that people being recognizing, representing, and reasoning about group-based patterns of inequity during the first years of life. We first synthesize recent research on what children learn about group-based social hierarchies as well as how this learning occurs. We then discuss how children not only learn about societal structures but become active participants in them. Studying the origins and development of children's thoughts and behavior regarding group-based social hierarchies provides valuable insight into how systems of inequity are perpetuated across generations and how intergroup biases related to wealth, power, and status may be mitigated and reshaped early in development.

BACKGROUND: Evidence about physical activity of young children across developmental and health states is very limited. Using data from an inclusive UK cohort, ActiveCHILD, we investigated relationships between objectively measured physical activity, child development, social context, and health-related quality of life (HRQoL). METHODS: Children (12-36 months), purposively sampled across health pathways, developmental abilities, and sociodemographic factors, were recruited through thirteen National Health Service organisations in England. Data were collected from 07/2017 to 08/2019 on: weekly physical activity (3-7 days) using waist-worn accelerometer (ActiGraph 3GTX); sociodemographics, parent actions, child HRQoL, and child development using questionnaires; and child health conditions using clinical records. A data-driven, unsupervised method, called hidden semi-Markov model (HSMM) segmented the accelerometery data and provided estimates of the total time spent active (any intensity) and very active (greater intensity) for each child. Relationships with the explanatory factors were investigated using multiple linear regression. FINDINGS: Physical activity data were obtained for 282 children (56% females, mean age 21 months, 37.5% with a health condition) covering all index of multiple deprivation deciles. The patterns of physical activity consisted of two daily peaks, children spending 6.44 (SD = 1.39) hours active (any intensity), of which 2.78 (SD = 1.38) hours very active, 91% meeting WHO guidelines. The model for total time active (any intensity) explained 24% of variance, with mobility capacity the strongest predictor (β = 0.41). The model for time spent very active explained 59% of variance, with mobility capacity again the strongest predictor (β = 0.76). There was no evidence of physical activity explaining HRQoL. INTERPRETATION: The findings provide new evidence that young children across developmental states regularly achieve mainstream recommended physical activity levels and challenges the belief that children with development problems need lower expectations for daily physical activity compared to peers. Advancing the rights of all children to participate in physical activity requires inclusive, equally ambitious, expectations for all.

Objective To examine the effects of parental Medicaid eligibility on parental health, parenting practices, and child development in low-income families. Methods Longitudinal analysis using data from the Early Child Longitudinal Study-Kindergarten: 2011 to 2016. Outcomes included parental self-rated health, parental depressive symptoms, parents’ communication and warmth toward children, and children's social skills and externalizing and internalizing behaviors. We estimated 2-way (individual and year) fixed effects models using Medicaid eligibility as a continuous variable, controlling for changing economic conditions, changes in family structure, and state-specific trends. We then estimated triple difference models comparing lower income families to those with higher incomes. Finally, we estimated difference-in-difference models and used entropy weights in order to account for differences in trends prior to 2014 for some outcomes. Results In fixed effects models, expanding Medicaid eligibility by 100% of the federal poverty line is associated with a 12.7 percentage point reduction in parents’ report of having fair or poor health (95% confidence interval [CI], -23.9, -1.5) and a 1.15-point improvement on a 12-point scale of parental warmth towards children (95% CI, 0.15, 2.16). Results were substantively similar in entropy-balanced difference-in-differences models. In triple difference models, expanded Medicaid eligibility is associated with a 0.46 point improvement in warmth (95% CI, 0.10, 0.83) but not improved parental health. No significant effects for child behavior or other outcomes were detected. Conclusions Expanding Medicaid for parents may have implications for intergenerational family functioning that could lead to broader social benefits.

Early Intervention (EI) programs promote early childhood development but remain underutilized. Few studies have examined correlations with completion of EI referrals using a standardized referral system. Our study examined a minority, underserved population for characteristics that affect this critical step.Subjects were referred from an inner-city pediatric primary care clinic for EI evaluation from 3/1/15-5/31/18. Subjects were3 years of age at the time of referral, received pediatric care at the clinic, and were referred for EI. The dependent variable was completion of EI evaluation, verified by the medical record. Independent variables included demographic, maternal (eg, depression), child (eg, chronic illness), and referral characteristics. A multivariable logistic regression model was used to determine the predictors for completing an evaluation.Of 181 children referred to EI, 61.9% completed an EI evaluation; the average age was 18.9 (SD 7.4) months at first referral. For every additional month of age at the initial referral, a child was 5.0% less likely to complete an evaluation (adjusted odds ratio [aOR], 0.95; 95% confidence interval [CI], 0.90-0.99; P = .02). Two factors more than doubled the odds of completing an EI evaluation: having a chronic medical illness at the time of referral (aOR = 2.41, CI 1.21-4.79; P = .01), and being a child from a non-English speaking family (aOR = 2.22, CI 1.09-4.50; P = .03).The child's age and medical history, and language spoken at home affected the odds of successfully completing an EI evaluation. These findings can help clinicians target families at risk of failing to complete EI programs.

Primary care centers are trialing open access scheduling models to expand access. Given evidence linking irregular caregiver work schedules with adverse child developmental outcomes, we hypothesized that children presenting for unscheduled "walk-in" visits would have higher odds of developmental concerns than those presenting for scheduled visits.We conducted a retrospective review of electronic health record data for children aged 6 to 66 months visiting an academic pediatric primary care center between July 1, 2013 and February 1, 2019. Our primary outcome was presence of developmental concerns, defined by results below cutoff on a child's AgesStages Questionnaire, Third Edition (ASQ-3). We examined associations between visit stream (unscheduled vs scheduled; time of day) and ASQ-3 using multivariable logistic regression, adjusting for child demographics, visit type (well-child vs ill), and responses to a standardized social history questionnaire.Of 11,169 eligible total encounters each for a unique child, 8% were unscheduled (n = 848); 19% had developmental concerns in at least one domain (n = 2100). Twenty-eight percent of children presenting for unscheduled visits had developmental concerns compared to 18% of those presenting for scheduled visits (P.0001). Compared to those presenting for scheduled well-child visits, children presenting for unscheduled ill visits had a higher odds of an ASQ-3 score below cutoff (adjusted odds ratio 2.02; 95% confidence interval, 1.54-2.65).As pediatric primary care centers implement open access scheduling models, they should be prepared to identify and respond to developmental concerns at a rate that may be higher than what is typically seen during scheduled visits.

Introduction The long-term impact of physical activity during early life on the risk of depression in later stages of adulthood remains unclear. This study examines the association between physical activity during childhood and adolescence and the incidence of depressive symptoms in early, middle, and late adulthood. Methods Data from a birth cohort (the 1958 National Child Development Survey), including births (N=17,415) in England, Wales, and Scotland, were used. After birth, 11 more follow-ups were carried out between ages 7 and 62 years (2020). Leisure-time physical activity was assessed through a self-reported questionnaire. Psychological measures were assessed with the teacher-rated Bristol Social Adjustment Guide, the teacher-rated Rutter scale, and the self-rated Malaise Inventory. Leisure-time physical activity and psychological symptoms were examined in all the 11 follow-up assessments included in this study. Best-fit model was used to obtain hazard ratios and 95% CIs of depression symptoms by physical activity status in different ages, including demographic, behavioral, and health-related variables as potential confounders. Results After multivariate analysis, being physically active at age 16 years reduced the risk of incident elevated depressive symptoms (hazard ratio=0.73, 95% CI=0.62, 0.85) throughout adulthood. The long-term impacts of physical activity practiced at age 16 years persisted throughout adulthood up to age 62 years. Conclusions Adolescence is a critical early-life period to promote physical activity for reducing the incidence of elevated depressive symptoms throughout adulthood. Public health policies should promote healthy lifestyles during the lifespan to reduce both the burden of physical inactivity and depressive symptoms at the population level.

Background In the last decades, the birth of premature babies has increased, it is important to know the impact of certain variables, especially in the most vulnerable groups. Purpose To analyse the relationship of gestational age (GA), weight and sex of the children, as well as the educational level and age of the parents with the cognitive, motor and language development of a group of very preterm births, assessed at 36 months. Design and methods The research followed a descriptive, observational and cross-sectional design. Children's development was measured using the Bayley-III Scale. Descriptive analysis, bivariate and linear regression models were carried out. Results Although the cognitive, motor and language development is within average levels, worse results are evidenced in the group of extreme premature, as opposed to the very premature. Boys score lower than girls, with these differences being more pronounced in the motor area. It also shows how the education level of both parents is related to the levels of development at 3 years of age of children born very prematurely, especially in language. Conclusions Lower GA, male sex and lower parental educational level are associated with higher risk of developmental difficulties. Practice implications The findings of this study are relevant to clinical practice because they suggest to develop protocols of evaluation and the follow up of all premature children beyond 36 months, as well as developing specific intervention programmes for the most vulnerable of the premature groups.

Magnetic resonance imaging (MRI) scoring systems are used in the neonatal period to predict outcome in infants with neonatal encephalopathy. Our aim was to assess the relationship between three MRI scores and neurodevelopmental outcome assessed using Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), at two years in infants with neonatal encephalopathy.Term-born neonates with evidence of perinatal asphyxia born between 2011 and 2015 were retrospectively reviewed. MRI scanning was performed within the first two weeks of life and scored using Barkovich, National Institute of Child Health and Human Development (NICHD) Neonatal Research Network (NRN), and Weeke systems by a single assessor blinded to the infants clinical course. Neurodevelopmental outcome was assessed using composite scores on the Bayley-III at two years. Multiple linear regression analyses were used to assess the association between MRI scores and Bayley-III composite scores, with postmenstrual age at scan and sex included as covariates.Of the 135 recruited infants, 90 infants underwent MRI, and of these, 66 returned for follow-up. MRI abnormalities were detected with the highest frequency using the Weeke score (Barkovich 40%, NICHD NRN 50%, Weeke 77%). The inter-rater agreement was good for the Barkovich score and excellent for NICHD NRN and Weeke scores. There was a significant association between Barkovich, NICHD NRN, and Weeke scores and Bayley-III cognitive and motor scores. Only the Weeke score was associated with Bayley-III language scores.Our findings confirm the predictive value of existing MRI scoring systems for cognitive and motor outcome and suggest that more detailed scoring systems have predictive value for language outcome.

Infant-parent attachment has been theoretically proposed to serve a key regulatory function for children's emotion, cognition, and behavior, with secure attachment leading to more favorable outcomes, but much of the research supporting this claim has been conducted solely on infant-mother dyads. While research on infant-father attachment has gained traction, studies including fathers often examine their contributions as independent from mothers, which may overlook the interacting influence of multiple attachment relationships on child development. Here, we use a new approach in which we consider infant attachment to both mothers and fathers as a configuration. This study examined whether infant attachment configurations to both mothers and fathers predicted effortful control, compliance, and defiance during toddlerhood. Using data from a longitudinal study on socio-emotional development, 117 infants participated in the Strange Situation, first with their mothers at 12 months, and then again with their fathers at 14 months to assess attachment. When toddlers were 20 months of age, mothers completed a questionnaire assessing toddlers’ effortful control, and toddlers were video recorded with their mothers and fathers in a gratification delay and clean-up task during a laboratory visit. Toddlers’ compliance and defiance towards parents were coded. Using linear mixed models, attachment configuration in infancy significantly distinguished effortful control, compliance, and defiance in toddlerhood. Infants with a secure attachment only to fathers had significantly lower effortful control and higher defiance at 20 months than the other 3 attachment configurations. In contrast, infants with a secure attachment to mothers were significantly more compliant than infants without a secure attachment to mothers. Our findings provide evidence that when analyzed from a family systems perspective, attachment security (and insecurity) to mothers and fathers may be functionally distinct for children's developing socio-emotional competence.

Objective To combat the wide-spread transmission of COVID-19, many countries, including the United Kingdom, have imposed nationwide lockdowns. Little is known about how these public health safety measures affect pregnant mothers and their offspring. This study aimed to explore the impact of COVID-19 public health safety measures on births in Scotland. Study Design Cross-sectional study. Methods Using routinely collected health data on pregnancy and birth in Scotland, this study compares all births (N = 7342) between 24th of March and May 2020 to births in the same period in 2018 (N = 8323) to investigate the potential negative impact of public health safety measures introduced in Scotland in spring 2020. Birth outcomes were compared using Mann-Whitney-U tests and chi-square tests. Results Mothers giving birth during the pandemic tended to combine breastfeeding and formula-feeding rather than exclusively breastfeed or exclusively formula-feed, stayed in hospital for fewer days and more often had an epidural or a spinal anaesthetic compared to women giving birth in 2018. Conclusion Overall, results suggest little impact of public health safety measures on birth outcomes. Further research is needed to explore the longer-term impacts of being born in the pandemic on both maternal mental health and child development.

Family engagement in early learning and education is considered a key predictor of children's development. However, little is known about the link between family engagement in early learning opportunities in sociocultural diverse contexts, particularly in low- and-middle-income countries. This study examined the associations of family engagement in home learning activities (e.g., reading books, naming things) and in early childhood care and education centers (ECCE; e.g., attending meetings or workshops, helping inside the classroom) with young children's emergent literacy and numeracy, social-emotional functioning, motor development, and executive functions, as measured through direct assessment. Data came from a nationally-representative sample of public ECCE centers in Colombia serving 3–5-year-old children (N = 3069). Multilevel model analyses showed that home-based family engagement was associated with higher emergent numeracy, emergent literacy, social-emotional functioning, and motor development, whereas center-based family engagement was associated only with higher emergent numeracy and literacy development. These results suggest that interventions and policies designed to improve family engagement in early learning opportunities both at the ECCE centers and at the home could have positive and independent effects on early childhood development.

This pilot outcome evaluation assesses the effectiveness of an online curriculum, the Keystones of Development, aimed at improving residents' knowledge, attitudes, and reported behaviors around promoting positive parenting and childhood development in well-child visits.We used an explanatory mixed-methods approach, including a single-arm pre-posttest of intervention effects on self-reported behavioral outcomes (discussing, modeling, and praising) and secondary outcomes (knowledge, perceived barriers, attitudes, and self-efficacy). Following this, a subset of residents participated in in-depth interviews to describe participant responses to the intervention.The study was conducted at 8 pediatric residency programs across the United States with 67 pediatric residents (mean age = 29; 79% female; 57% PGY1). Within one month postintervention, there was a statistically significant increase in the behaviors that promote positive parenting: discussing (P.01;d = 0.73) and modeling (P.01;d = 0.61) but not praising (P = .05; d = 0.3). Significant changes in the secondary outcomes: knowledge (P.01), perceived barriers, (P.01), and retrospective self-efficacy (P.01) were seen. Interviews revealed that integration of curriculum content into clinical practice was due to the relevance of the material to primary care and the modeling of how to apply in the clinical setting. Curriculum format, content, and clinical application helped participants weave recommendations into the well-child visit.In this study, we demonstrated that the online curriculum, Keystones of Development, increased resident behaviors, knowledge, and self-efficacy, and decreased perceived barriers to promote parenting behaviors associated with improved child development outcomes in well-child visits. These findings were observed across participants demonstrating equal success regardless of demographic characteristics or study site.

Background A large proportion of infants in low- and middle-income countries are stunted. These infants are often fed complementary foods that are low-quality, primarily in terms of protein and micronutrients. Objectives We aimed to test 2 milk–cereal mixes supplemented with modest and high amounts of protein during 6–12 mo of age, compared with no supplementation, for their effect on length-for-age z score (LAZ) at 12 mo of age. Methods Eligible infants (6 mo plus ≤29 d) were randomly assigned to either of the 2 interventions (modest- and high-protein) or a no supplement group. The milk–cereal mixes provided ∼125 kcal, 30%–45% energy from fats, and 80%–100% RDA of multiple micronutrients (MMN). The modest-protein group received 2.5 g protein [protein energy ratio (PER): 8%; 0.75 g from milk source] and the high-protein group received 5.6 g protein (PER: 18%, 1.68 g from milk source). One packet was given daily for 180 d. Counseling on continued breastfeeding and optimal infant-care practices was provided to all. Results We enrolled 1548 infants (high-protein: n = 512; modest-protein: n = 519; and no supplement: n = 517). Compared with the no supplement group, there was an improvement in LAZ [adjusted mean difference (MD): 0.08; 95% CI: 0.01, 0.15], weight-for-age z score (MD: 0.12; 95% CI: 0.06, 0.19), weight-for-length z score (MD: 0.11; 95% CI: 0.02, 0.19), and midupper arm circumference z score (MD: 0.10; 95% CI: 0.02, 0.18) in the high-protein group at 12 mo of age. No significant differences for these anthropometric indicators were noted between the modest-protein and no supplement groups or between the high- and modest-protein groups. Conclusions Cereal mixes with higher amounts of milk-based protein and MMN may lead to improvement in linear growth and other anthropometric indexes in infants, compared with no supplementation. This trial was registered at ctri.nic.in as CTRI/2018/04/012932.

Brain development during the prenatal period is rapid and unparalleled by any other time during development. Biological systems undergoing rapid development are at higher risk for disorganizing influences. Therefore, certain prenatal exposures impact brain development, increasing risk for negative neurodevelopmental outcome. While prenatal exposures have been associated with cognitive and behavioral outcomes later in life, the underlying macroscopic brain pathways remain unclear. Here, we review magnetic resonance imaging (MRI) studies investigating the association between prenatal exposures and infant brain development focusing on prenatal exposures via maternal physical health factors, maternal mental health factors, and maternal drug and medication use. Further, we discuss the need for studies to consider multiple prenatal exposures in parallel and suggest future directions for this body of research.

Graphical abstract, Highlights • Associations between caregiver-infant behaviours during social interactions and brain development outcomes were investigated. • Caregivers' and infants' behaviours in interactions related to children’s structural, functional and connectivity measures. • Concurrent associations between behavioural and brain measures were apparent as early as three months postnatally. • Long-term associations between behaviours in early interactions and brain development outcomes were observed decades later. • Individual differences in early interactions and associated brain development is an important avenue for further research., From birth, interactions with others are an integral part of a person’s daily life. In infancy, social exchanges are thought to be critical for optimal brain development. This systematic review explores this association by drawing together infant studies that relate adult-infant behaviours – coded from their social interactions - to children’s brain measures collected during a neuroimaging session in infancy, childhood, adolescence or adulthood. In total, we identified 55 studies that explored associations between infants’ social interactions and neural measures. These studies show that several aspects of caregiver-infant behaviours are associated with, or predict, a variety of neural responses in infants, children and adolescents. The presence of both concurrent and long-term associations - some of which are first observed just a few months postnatally and extend into adulthood - open an important research avenue and motivate further longitudinal studies.

BACKGROUND: Although DHA (22:6n–3) is critical for fetal development, results from randomized controlled trials (RCTs) of prenatal DHA supplementation report inconsistent effects on offspring health. Variants in fatty acid desaturase (FADS) genes that regulate the conversion of n–3 and n–6 essential fatty acids into their biologically active derivatives may explain this heterogeneity. OBJECTIVES: We investigated the effect of prenatal DHA supplementation on the offspring metabolome at age 3 mo and explored differences by maternal FADS single-nucleotide polymorphism (SNP) rs174602. METHODS: Data were obtained from a double-blind RCT in Mexico [POSGRAD (Prenatal Omega-3 Fatty Acid Supplementation and Child Growth and Development)] in which women (18–35 y old) received DHA (400 mg/d) or placebo from mid-gestation until delivery. Using high-resolution MS with LC, untargeted metabolomics was performed on 112 offspring plasma samples. Discriminatory metabolic features were selected via linear regression (P

Poverty-related disparities appear early in life in cognitive, language, and social-emotional development, and in growth, especially obesity, and have long-term consequences across the life course. It is essential to develop effective strategies to promote healthy behaviors in pregnancy and the early years of parenthood that can mitigate disparities. Primary preventive interventions within the pediatric primary care setting offer universal access, high engagement, and population-level impact at low cost. While many families in poverty or with low income would benefit from preventive services related to both development and growth, most successful interventions have tended to focus on only one of these domains. In this manuscript, we suggest that it may be possible to address both development and growth simultaneously and effectively. In particular, current theoretical models suggest alignment in mechanisms by which poverty can create barriers to parent-child early relational health (i.e., parenting practices, creating structure, and parent-child relationship quality), constituting a final common pathway for both domains. Based on these models and related empirical data, we propose a strength-based, whole child approach to target common antecedents through positive parenting and prevent disparities in both development and growth; we believe this approach has the potential to transform policy and practice. Achieving these goals will require new payment systems that make scaling of primary prevention in health care feasible, research funding to assess efficacy/effectiveness and inform implementation, and collaboration among early childhood stakeholders, including clinicians across specialties, scientists across academic disciplines, and policy makers.

Background and aims Childhood overweight and obesity are lifetime risk factors for cardiovascular disease but the relationship between dynamic body mass index (BMI) change and cardiovascular structure and function in early childhood remains unclear. Methods and results This cohort study consisted 525 participants with 6 distinct representative growth patterns to examine the associations between BMI growth patterns and subsequent cardiovascular structure and function at age 4. BMIs were obtained at birth, 2 and 4 years old. Cardiovascular assessments were performed, including blood pressure (BP), cardiac geometric parameters, left ventricular (LV) function, speckle-tracking, integrated backscatter analysis and carotid intima-media thickness. Compared to the stable normal BMI pattern, children with the stable overweight (OW) pattern had significantly greater LV anatomic parameters in fully adjusted models. Children with the catch-up (CU) pattern revealed a uniform trend and had poorer strain. LV diameters and integrated backscatter signals were larger for those with BMI gain and lose pattern. Children with BMI lose pattern showed improved tendency involving LV mass index and BP. Both OW and CU patterns were associated with high systolic BP [odds ratio (95% CI): OW: 3.67 (1.08, 12.47); CU: 4.24 (1.75, 10.28)]. Compared to static BMI measurements at birth, 2 and 4 years old, dynamic BMI growth patterns were more predictive of cardiovascular structure and function at 4. Conclusions Children with overweight-related BMI growth patterns in early childhood experienced undesirable cardiovascular functional or structural changes as early as 4 years old, indicating that early intervention is needed and potentially beneficial.

Background While the negative impact of peri-natal depression is well-documented in high-income countries, the long-term effects across the life course in low and middle-income countries is less clear. Children's adjustment over the first five years is examined as a function of patterns of maternal depressed mood. Methods Pregnant women in 24 peri-urban townships (N = 1,238) were randomized to a home-visiting intervention or standard care and reassessed five times, with high retention. There were no intervention effects on children past 18 months. Multilevel regression models examined the impact of depressed mood on child outcomes. Using the Edinburgh Postnatal Depression Scale, four patterns of maternal depressed mood were identified: never (40.6%); antenatal (13.0%); early childhood (26.1%); and recurrent episodes of depressed mood (20.3 %). Findings Mothers' patterns of depressive symptoms and child outcomes were similar, regardless of intervention. Never depressed mothers were significantly younger, had higher income, less food insecurity, were more likely to have electricity, be living with HIV or have an HIV positive partner, and had fewer problems with alcohol than depressed mothers. Children of mothers who experienced depressed mood weighed less, were more aggressive, and were hospitalized more often than children of never depressed mothers, but were similar in cognitive and social development. Interpretations Depressed mood, has significant negative impacts on South African children's growth and aggressive behavior. The timing of maternal depressed mood was less important than never having a depressed mood or a recurrent depressed mood. Funding There were no funding conflicts in executing this trial.

Objectives There is a critical need to monitor the development of children around the world, and in Brazil, this need is substantial since there is a paucity of assessment tools. This study aimed to describe the design and provide evidence of reliability and validity for the short version of the Dimensional Inventory for Child Development Assessment (IDADI-short). Methods A sample of 1,865 biological mothers of children aged 4–72 months (M = 34.8, SD = 20.20) completed the IDADI to assess Cognitive, socio-emotional, Expressive, and Receptive Language and Communication, Fine and Gross Motor, and Adaptive Behavior development. The psychometric properties of a total of 118 subscales of IDADI were obtained and the IDADI-short age-specific scores were correlated with the original inventory, and criteria variables such as neurodevelopment diagnosis, socioeconomic status, and sex. Results Item Response Theory analysis, Cronbach's Alpha, and McDonald’s Omega indicated excellent internal consistency and optimal participant discrimination after minor alterations. IDADI-short scores were strongly associated with the original inventory, with high sensibility and specificity precision for developmental delays. Significant associations with relevant criteria variables were also observed. Conclusion Findings support the use of IDADI-short as a parental measure of young children’s development.

Variability in the FADS2 gene, which codifies the Delta-6 Desaturases and modulates the conversion of essential n-3 and n-6 fatty acids into long-chain polyunsaturated fatty acids, might modify the impact of prenatal supplementation with n-3 docosahexaenoic acid (DHA) on neurodevelopment.To assess if maternal FADS2 single nucleotide polymorphisms (SNPs) modified the effect of prenatal DHA on offspring development at 5 years.We conducted a post-hoc interaction analysis of the POSGRAD randomized controlled trial (NCT00646360) of prenatal supplementation with algal-DHA where 1094 pregnant women originally randomized to 400 mg/day of preformed algal DHA or a placebo from gestation week 18-22 through delivery. In this analysis, we included offspring with information on maternal genotype and neurodevelopment at 5 years (DHA = 316; Control = 306) and used generalized linear models to assess interactions between FADS2 SNPs rs174602 or rs174575 and prenatal DHA on neurodevelopment at 5 years measured with McCarthy Scales of Children's Abilities (MSCA).Maternal and offspring characteristics were similar between groups. At baseline, mean (±standard deviation) maternal age was 26 ± 5 years and schooling was 12 ± 4 years. Forty-six percent (46%) of the children were female. Maternal minor allele frequencies were 0.37 and 0.33 for SNPs rs174602 and rs174575, respectively. There were significant variations by SNP rs174602 and intervention group (p for interactions0.05) where children in the intervention group had higher MSCA scores on the quantitative (DHA: mean ± SEM = 22.6 ± 0.9 vs. Control = 19.1 ± 0.9, mean difference (Δ) = 3.45; p = 0.01) and memory (DHA = 27.9 ± 1.1 vs. Control = 23.7 ± 1.1, Δ = 4.26; p = 0.02) scales only among offspring of TT (minor allele homozygotes).Maternal FADS2 SNP rs174602 modified the effect of prenatal DHA on cognitive development at 5 years. Variations in the genetic make-up of target populations could be an important factor to consider for prenatal DHA supplementation interventions.

Highlights • Maternal self-harm ideation predicted long-term offspring depression and self-harm. • This relationship occurs independently of maternal depression. • Analyses also indicate a dose-response effect. • No interaction of maternal depression and self-harm thoughts with offspring outcomes., Introduction Depression and self-harm are leading causes of disability in young people, but prospective data on how maternal depression and self-harm thoughts contribute to these outcomes, and how they may interact is lacking. Methods The study sample consisted of 8,425 mothers and offspring from the Avon Longitudinal Study of Parents and Children, an ongoing birth cohort study. Exposures were maternal self-harm ideation and depression measured using the Edinburgh Postnatal Depression Scale, collected at eleven time points over the period 18 weeks’ gestation to 18 years post-partum. Outcomes were offspring past-year major depressive disorder and lifetime self-harm assessed at age 24. Results Nearly one-fifth (16.7%) of mothers reported thoughts of self-harm on at least one of the eleven assessment points. The frequency of maternal self-harm ideation was related to both outcomes in a dose-response manner. Young adults whose mothers had self-harm ideation on 5–11 occasions were over three times more likely (Odds ratio (OR), 3.32; 95% CI, 1.63–6.76) to be depressed and over 1.5 times as likely (OR, 1.55; 95% CI, 0.73, 3.29) to have self-harmed than their peers whose mothers had never reported self-harm thoughts. Maternal self-harm thoughts remained associated with both offspring outcomes independent of maternal depression, and no evidence was found for an interaction between the two exposures. Discussion Clinicians collecting data on maternal depression may consider paying attention to questions about self-harm ideation in assessments. Examining accumulated maternal self-harm ideation over time may provide insights into which children are most at risk for later self-harm and depression.

Background The association between maternal intrusive parenting and infant fear remains poorly understood, especially in the persistence of maternal postpartum depression. The current study investigated the moderating role of maternal postpartum depressive symptoms on the bidirectional link between maternal intrusive parenting and infant fear, among a sample of low-income, rural mothers. Methods . A sample of 1,292 mothers reported their depressive symptoms at 2, 6, 15, and 24 months postpartum, whereas their intrusive parenting behavior and infant fear were observed at infants age 6, 15, and 24 months. Results . Latent growth curve models revealed that maternal postpartum depressive symptoms increased over 2 years. From 6 months to 24 months, maternal intrusive parenting remained stable, and infant fear increased. Moderation analyses revealed that when mothers had low levels of initial depressive symptoms, a higher initial level of maternal intrusive parenting predicted a faster increase of infant fear. Additionally, when mothers’ depressive symptoms showed a fast increase, a higher initial level of infant fear predicted a faster reduction in maternal intrusive parenting. Limitations . The low-income, rural community sample limited the generalizability of the current findings. Conclusions . The interplay between maternal intrusive parenting and infant fear supports a transactional model of child development in the context of maternal depression, with implications for future research and intervention efforts.

Background Maternal mental health is linked to early childhood development; yet there is a gap in evidence-based interventions for low-resource settings. This study estimates the impact of ‘Integrated Mothers and Babies Course and Early Childhood Development’ (iMBC/ECD), a cognitive-behavioral, group-based intervention, on maternal depression and early childhood social-emotional development in Siaya County, Kenya. Methods This quasi-experimental study enrolled 417 pregnant women and mothers of children under age 2 across two sub-counties in Siaya County. The intervention area had 193 women in 23 groups implementing iMBC/ECD and the control area had 224 women in 30 groups exposed to ECD only content. Mother/index child dyads were followed for two years. To estimate the causal treatment effect from the non-randomized design, we implemented the propensity score weighting method with inverse probability weights. Results At baseline, 10.2% of participants endorsed moderate/severe depressive symptoms. At 14-months post-intervention, 7.4% endorsed moderate/severe depression. Overall, iMBC/ECD intervention did not have a significant impact on reducing maternal depression or improving children's social and emotional development. However, sub-group analyses revealed that iMBC/ECD was associated with lowered depressive symptoms among women with no/low education, four or more children and/or no experience of intimate partner violence in the past year. Women with high program attendance (more than half of 14 sessions) also experienced consistently fewer depressive symptoms compared to those with lower attendance. Limitations Non-randomized study, sub-group analyses are exploratory. Conclusions The iMBC/ECD program may have the potential to improve maternal mental health and early child development for more targeted vulnerable populations.

Summary Background & aims Child growth impairments are rampant in sub-Saharan Africa. To combat this important health problem, long-term follow-up studies are needed to examine possible benefits and sustainability of various interventions designed to correct inadequate child growth. Our aim was to perform a follow-up study of children aged 60–72 months whose mothers participated in a two-armed cluster-randomized education intervention trial lasting 6 months in rural Uganda when their children were 6–8 months old with data collection at 20–24 and at 36 months. The education focused on nutrition, hygiene, and child stimulation. Methods We measured growth using anthropometry converted to z-scores according to WHO guidelines. We also included assessments of body composition using bioimpedance. We used multilevel mixed effect linear regression models with maximum likelihood method, unstructured variance-covariance structure, and the cluster as a random effect component to compare data from the intervention (receiving the education and routine health care) with the control group (receiving only routine health care). Results Of the 511 children included in the original trial, data from 166/263 (63%) and 141/248 (57%) of the children in the intervention and control group, respectively, were available for the current follow-up study. We found no significant differences in any anthropometrical z-score between the two study groups at child age of 60–72 months, except that children in the intervention group had lower (P = 0.006) weight-for-height z-score than the controls. There were no significant differences in the trajectories of z-scores or height growth velocity (cm/year) from baseline (start of original trial) to child age of 60–72 months. Neither did we detect any significant difference between the intervention and control group regarding body composition (fat mass, fat free mass, and total body water) at child age 60–72 months. Separate gender analyses had no significant impact on any of the growth or body composition findings. Conclusion In this long-term study of children participating in a randomized maternal education trial, we found no significant impact of the intervention on anthropometrical z-scores, height growth velocity or body composition.

The ability to shift from current to future perspective is pivotal to future-oriented cognition. However, the relationship between executive function, theory of mind and the ability to predict future preferences of self and others has received little focus, particularly across different cultures. With two distinct cultural groups in Britain (N = 92 participants) and China (N = 90), we investigated 3 to 5-year-olds’ understanding of their own versus a peer’s current and future preferences. We administered a battery of standardised executive function (inhibition, cognitive flexibility, working memory) and theory of mind tasks to examine the underlying relationship between these cognitive abilities and children’s ability to predict future preferences. Consistent with previous literature, we found significant age-related performance in the future preference task. Furthermore, our study indicates that there may be a universal developmental trajectory in British and Chinese children’s future-oriented cognition. We found that children were more accurate when predicting for their peers than predicting for themselves. Also, their performance improved when they had the opportunity to identity their current preferences before anticipating the future. Chinese children outperformed their British counterparts on cognitive inhibition and cognitive flexibility tasks, with no country-related differences in their working memory, motor inhibition or theory of mind ability. After controlling for age, children’s performance in the inhibition and cognitive flexibility tasks were significantly correlated with the prediction of their own – though not peer’s - future preferences. We discuss these findings in relation to the conflicts between multiple perspectives and the cognitive correlates of future-oriented cognition.

To determine feasibility and explore effects of literacy promotion using e-books versus board books on the home reading environment, book reading, television use, and child development.Randomized controlled trial comparing digital literacy promotion (DLP) using e-books to standard literacy promotion (SLP) using board books among Medicaid-eligible infants. DLP participants received e-books on home digital devices, while SLP participants received board books at well visits between 6 and 12 months of age. Differences in StimQ Read Subscale (StimQ-Read) scores, parent-reported reading and television use, and Bayley Scales of Infant Development-3rd Edition (Bayley-3) scores between groups were assessed using intention-to-treat analysis.A total of 104 Medicaid-eligible infants were enrolled and randomized from 3 pediatric practices. There were no differences in sociodemographic characteristics between groups at baseline. Children in the DLP group initially had lower StimQ-Read scores but showed similar increases in StimQ-Read scores over time as children in the SLP group. Parents in the DLP group reported greater use of digital devices to read or engage their child (65% vs 23%, P.001) but similar board book reading and television viewing. There were no differences between groups in cognitive or motor scale scores, but DLP participants had marginally lower language scales scores (DLP 85.7 vs SLP 89.7; P = .10) at the 6-month follow-up.Literacy promotion using e-books was feasible and associated with greater e-book usage but no difference in board book reading, television viewing, or home reading environment scores. A potential adverse impact of e-books on language development should be confirmed in future study.

Macrocephaly is commonly encountered in the primary care provider's office. It is defined as an occipitofrontal circumference that is greater than 2 standard deviations above the mean for the child's given age. Macrocephaly is a nonspecific clinical finding that may be benign or require further evaluation. An algorithmic approach is useful for aiding in the clinical decision-making process to determine if further evaluation with neuroimaging is warranted. Abnormal findings may signify a harmful underlying cause, requiring referral to a genetic specialist or neurosurgeon.

Background Limited knowledge exists on outcomes of children exposed prenatally to chemotherapy for breast cancer (BC). The purpose of this study was to compare long-term neurocognitive, behavioral, developmental, growth, and health outcomes of children exposed in-utero to chemotherapy for BC. Methods This is a multi-center matched cross-sectional cohort study involving seven cancer centers across the region of Southern Ontario (Canada), and the Hospital for Sick Children (Toronto, Ontario). Using standardized psychological and behavioral tests, we compared cognitive and behavioral outcomes in children exposed to chemotherapy during pregnancy for BC to age-matched pairs exposed to known non-teratogens. Results We recruited 17 parent-child pairs and their matched controls. There were more preterm deliveries in the chemotherapy-exposed group compared to controls (p, Highlights • Limited knowledge exists on outcomes of children exposed prenatally to chemotherapy for breast cancer (BC). • We compared cognitive and behavioral outcomes in children exposed to chemotherapy during pregnancy for BC to controls. • FSIQ of children in the chemotherapy group was significantly confounded by prematurity. • Chemotherapy was not found to be neurotoxic and did not affect pediatric health. • Pediatric implications of planned preterm birth for further treatment should be considered.

Objective To report vigilance attention outcomes from a cluster randomized controlled trial of early childhood development caregiver training for perinatally HIV-exposed/uninfected preschool-age children in rural Uganda. The Early Childhood Vigilance Test (ECVT) provides a webcam recording of proportion of time a child views an animation periodically moving across a computer screen. Study design Sixty mothers/caregivers received biweekly year-long training sessions of the Mediational Intervention for Sensitizing Caregivers (MISC), and 59 mothers received biweekly training about nutrition, hygiene, and health care. Children were tested for attention at baseline, 6 months, and 12 months with the ECVT, in terms of proportion of time spent viewing a 6-minute animation of animals greeting the child and moving across the computer monitor screen. Time viewing the animation were scored by trained observers using ProCoder program for webcam scoring of proportion of time the child faced the animation. Mixed-effects modeling was used to compare ECVT outcomes for the 2 intervention groups. Results Unadjusted and adjusted (for age, sex, height, and ECVT at baseline) group differences on ECVT significantly favored the MISC arm at 6 months (P = .03; 95% CI (0.01, 0.11), effect size = 0.46) but not at 12 months. Both groups made significant gains in sustained attention across the year-long intervention (P = .021) with no significant interaction effects between time and treatment arms or sex. Conclusions Caregiver early childhood development training enhanced attention in at-risk Ugandan children, which can be foundational to improved working memory and learning, and perhaps related to previous language benefits reported for this cohort.

BACKGROUND Growth failure in sub-Saharan Africa leads to a high prevalence of child stunting starting in infancy, and is attributed to dietary inadequacy, poor hygiene, and morbidity. OBJECTIVES To evaluate the impact of a program in Malawi providing a lipid-based nutrient supplement to infants from 6-23 months of age, accompanied by a social and behavior change communication intervention to optimize caregiver feeding and handwashing practices. METHODS This impact evaluation was a quasi-experimental, longitudinal study with 1 program and 1 comparison district. Infants were enrolled at 6-7 months of age. Anthropometry, child morbidity, and caregiver feeding and handwashing practices were assessed at enrollment and at 6, 12, and 18 month follow-ups (ages 6, 12, 18, and 24 months, respectively). Changes in the length-for-age z-score (LAZ), weight-for-length z-score (WLZ), and midupper arm circumference (MUAC) were compared using mixed-effects models. Program impacts on child stunting (LAZ < -2), wasting (WLZ < -2), morbidity, and feeding and handwashing practices were estimated using difference-in-differences. RESULTS We enrolled 367 infants across the program (n = 176) and comparison (n = 191) districts. The combined prevalences of stunting and wasting at enrollment were 42.1% and 1.4%, respectively, and did not differ by district. At enrollment, the prevalence of severe stunting (LAZ < -3) was higher in the program (15.5%) versus comparison (7.6%) district (P = 0.02), with corresponding lower LAZ scores (-1.9 vs. -1.7, respectively; P = 0.12). Growth velocities favored program children, such that LAZ, WLZ, and MUAC measurements increased by +0.12/y (P = 0.06), +0.12/y (P = 0.04), and +0.24 cm/y (P < 0.001), respectively, leading to comparable LAZ distributions across districts by 24 months of age. Program exposure was associated with 19.8 percentage point (pp) and 13.8 pp reductions in the prevalences of malaria (P = 0.001) and fever (P = 0.02), respectively, at the 18-month follow-up. Improvements of 20 pp (P < 0.01) in minimum dietary diversity and minimum acceptable diet were seen in the program versus comparison district at 18 months of follow-up. CONCLUSIONS The program improved child growth patterns, with benefits to health and diet apparent after 18 months of exposure. This trial was registered at clinicaltrials.gov as NCT02985359.

Objectives To develop a checklist describing features of normal and abnormal general movements in order to guide General Movement Assessment novices through the assessment procedure, to provide a quantification of General Movement Assessment; and to demonstrate that normal and abnormal GMs can be distinguished on the basis of a metric checklist score. Methods Three examiners used General Movement Assessment and the newly developed GM checklist to assess 20 videos of 16 infants (seven males) recorded at 31-45 weeks postmenstrual age (writhing general movements). Inter- and intra-scorer agreement was determined for General Movement Assessment (nominal data; Kappa values) and the checklist score (metric scale ranging from 0 to 26; Intraclass Correlation values). The scorers’ satisfaction with the usefulness of the checklist was assessed by means of a short questionnaire (score 10 for maximum satisfaction). Results The scorers’ satisfaction ranged from 8.44 to 9.14, which indicates high satisfaction. The median checklist score of the nine videos showing normal general movements was significantly higher than that of the eleven videos showing abnormal general movements (26 vs. 11, p < 0.001). The checklist score also differentiated between poor-repertoire (median = 13) and cramped-synchronized general movements (median = 7; p = 0.002). Inter- and intra-scorer agreement on (i) normal vs. abnormal general movements was good to excellent (Kappa = 0.68-1.00); (ii) the distinction between the four general movement categories was considerable to excellent (Kappa = 0.56-0.93); (iii) the checklist was good to excellent (ICC = 0.77-0.96). Conclusion The general movement checklist proved an important tool for the evaluation of normal and abnormal general movements; its score may potentially document individual trajectories and the effect of therapeutic intervention.

Objective Fewer than 50% of children with developmental delay are identified before they start school, and only 10% of those identified receive services. Between May 2014 and August 2016, the Home Visiting Collaborative Improvement and Innovation Network (HV-CoIIN) aimed to improve early detection and linkage to services so that 80% of children with an identified developmental concern would receive timely, targeted developmental support. Methods HV-CoIIN enrolled 13 home visiting programs in eight states and one tribe in a Breakthrough Series Collaborative (BTS). These programs tested interventions aligned with five key drivers: early detection, referral and follow-up, home visitor capacity, families engaged in developmental promotion, and data systems. Run charts were used to study measures. The main outcome was the percent of children with an identified concern that were linked to developmental support. Process measures included the percent of visits where parents were asked if they had any concerns about their child's development and the percent of children screened every six months. Results The percent of children with an identified developmental concern that received support increased from 70% to 82%. Parents were asked about developmental concerns at 95% of visits (baseline = 75%), and 90% of children were screened every six months (baseline = 51%). Conclusion Home visiting programs can reliably execute early detection and linkage to services for at-risk populations they serve. BTS holds promise for improving implementation of federal public health programs to improve population health outcomes.

Purpose This study aims to examine predictors of parent use of a child health home-based record and associations with child health/developmental outcomes. Design and methods Data for this study was obtained from a nationally representative study of Australian children from 2004 to 2016. The current study focuses on the kindergarten cohort of the Longitudinal Study of Australian Children, which enrolled children at the ages of 4–5 years. Logistic regression was used to analyse the data using Odds Ratio (OR) at 95% Confidence Interval (CI) and p-value of 0.05. Results A total of 4983 parent-child pairs participated at the beginning of the study in 2004, which reduced to 3089 (62%) by 2016. The most significant predictor of home-based record use was co-parenting, with single parents less likely to use the record (Adjusted OR = 0.633–95%CI:0.518–0.772). Similarly, child up-to-date immunisation was 31% higher among parents who used the record (OR = 1.313–95%CI:1.049–1.644). Children without a home-based record had increased odds of having various health/developmental concerns (p Conclusion The findings suggest that using a home-based record may have a long-term impact on child health and development. It is also possible that home-based records are more likely to be used by parents of relatively healthy children. Further work is needed to consider if home-based records need to be modified for parents of children with health/development problems. Practice implications Nurses and other primary care providers at forefront of family health should ensure proper use of child health home-based records as well as promote its use by parents and caregivers of children.

Background Previous validity studies of the Alberta Infant Motor Scale (AIMS), using raw scores and percentile curves for group comparisons, showed that infants in Brazil achieved gross motor milestones at later ages. Validity of the AIMS norms were later reassessed using a logistic regression model that placed the AIMS items on an age scale. Objectives Our study examined the validity of the AIMS norms for Brazilian infants using the recommended method for calculating and comparing item locations. Methods Data from 732 Brazilian infants (2009–11), 3 days to 18 months old, were compared to the AIMS normative sample (n = 2202). Logistic regression placed the AIMS items of both samples on age scales representing the age at which 50% of infants passed an item and compared the two datasets. Pearson correlation coefficient tested the association across samples. Results 47 of the 58 AIMS items met the criterion for stable regression to calculate item locations of the Brazilian dataset. Based on the age when 50% of the infants passed a criterion, most of the items from the Brazilian sample (n = 28) differed by two weeks or less compared to the Canadian normative sample. Conclusion The sequence and age for the emergence of AIMS items were similar between the Brazilian and Canadian samples. Canadian norms are appropriate for clinical decisions and research with Brazilian infants.

Summary Background & aims Maternal gestational infection is a well-characterized risk factor for offsprings’ development of mental disorders including schizophrenia, autism, and attention deficit disorder. The inflammatory response elicited by the infection is partly directed against the placenta and fetus and is the putative pathogenic mechanism for fetal brain developmental abnormalities. Fetal brain abnormalities are generally irreversible after birth and increase risk for later mental disorders. Maternal immune activation in animals models this pathophysiology. SARS-CoV-2 produces maternal inflammatory responses during pregnancy similar to previously studied common respiratory viruses. Method Choline, folic acid, Vitamin D, and n-3 polyunsaturated fatty acids are among the nutrients that have been studied as possible mitigating factors for effects of maternal infection and inflammation on fetal development. Clinical and animal studies relevant to their use in pregnant women who have been infected are reviewed. Results Higher maternal choline levels have positive effects on the development of brain function for infants of mothers who experienced viral infections in early pregnancy. No other nutrient has been studied in the context of viral inflammation. Vitamin D reduces pro-inflammatory cytokines in some, but not all, studies. Active folic acid metabolites decrease anti-inflammatory cytokines. N-3 polyunsaturated fatty acids have no effect. Conclusions Vitamin D and folic acid are already supplemented in food additives and in prenatal vitamins. Despite recommendations by several public health agencies and medical societies, choline intake is often inadequate in early gestation when the brain is forming. A public health initiative for choline supplements during the pandemic could be helpful for women planning or already pregnant who also become exposed or infected with SARS-CoV-2.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders worldwide, and in the majority of patients persists into adulthood. However, it remains unclear how maternal ADHD could affect pregnancy and birth as well as early mother-(father)-child interaction. There are several studies investigating the effect of depressed or anxious parents on parent-child-interactions in early infancy, but data about the influence of parental ADHD is lacking although it is a common mental disorder in parents. Additionally, the prescription of stimulant and other ADHD medication for adult ADHD patients is rising due to improved diagnostic procedures and a greater awareness of this disorder in adulthood among psychiatrists and psychologists. However, this leads to increased numbers of treated ADHD women that wish to have children or experience unplanned pregnancies while taking stimulant medication. In our systematic review we aimed at analysing the current evidence for the association of maternal ADHD with pregnancy and birth outcomes, pregnancy risks and health behaviour in pregnancy, as well as the association of parental ADHD with early parent-child interaction and early child development in the first 3 years. Furthermore, we reviewed recent evidence on the risks of stimulant and non-stimulant treatment for ADHD in pregnancy and lactation.

Objective: To study differences by sperm donor type in the psychological adjustment of the U.S. National Longitudinal Lesbian Family Study (NLLFS) offspring across three time periods from childhood to adulthood.Design: U.S.-based prospective cohort study.Setting: Paper-and-pencil questionnaires and protected online surveys.Patient(s): A cohort of 74 offspring conceived by lesbian parents using an anonymous (n = 26), a known (n = 26), or an open-identity (n = 22) sperm donor. Data were reported when offspring were ages 10 (wave 4), 17 (wave 5), and 25 (wave 6).Intervention(s): None.Main outcome measure(s): Achenbach Child Behavior Checklist administered to lesbian parents when offspring were ages 10 and 17 and the Achenbach Adult Self-Report administered to offspring at age 25.Result(s): In both relative and absolute stability, no differences were found in internalizing, externalizing, and total problem behaviors by donor type over 15 years. However, both externalizing and total problem behaviors significantly declined from age 10 to 17 and then increased from age 17 to 25. Irrespective of donor type, among the 74 offspring, the large majority scored continuously within the normal range on internalizing (n = 62, 83.8%), externalizing (n = 62, 83.8%), and total problem behaviors (n = 60, 81.1%).Conclusion(s): The results reassure prospective lesbian parents and provide policy makers and reproductive medicine practitioners with empirical evidence that psychological adjustment in offspring raised by lesbian parents is unrelated to donor type in the long term.

Background Difficulties in fine and gross motor skills are often overlooked as developmental problems, although approximately 6–13% of all school-age children have poor motor coordination. Understanding motor coordination is important from the perspective of school adaptation. This longitudinal cohort study aimed to determine whether fine and gross motor skills in preschool children predict later academic achievement and psychosocial maladaptation. Methods & Procedures Participants were 2,501 children from nursery and elementary schools (5–13 years old). The motor skills of preschool children were assessed by their nursery teacher immediately before entering elementary school. The Strengths and Difficulties Questionnaire and a standardized Japanese test were administered annually throughout elementary school. Results Early motor difficulties in preschool children had significant effects on their academic achievement and psychosocial maladaptation up until the sixth grade. Gross motor difficulties in preschool were associated with the later peer problems and worsened emotional symptoms. Conclusions Motor skills in preschool children are useful as a predictor of later psychosocial maladaptation and academic achievement.

Purpose Striking disparities persist in cardiovascular disease risk factors among minority youth. We examined the association between multiple indicators of neighborhood quality and minority youth fitness. Methods The primary exposure was the Child Opportunity Index (COI), a measure comprised of indicators that facilitate healthy child development. Outcome data were drawn from the 2018–2019 Fit2Play Study (Miami-Dade County, FL). Hotspot analysis evaluated COI spatial clustering. Generalized linear mixed models examined cross-sectional COI-fitness associations. Results The sample included 725 youth (53% Black, 43% Hispanic; 5–17 years). Significant neighborhood quality spatial clusters were identified (Gi*z-score = −4.85 to 5.36). Adjusting for sociodemographics, walkability was associated with lower percentiles in body mass index (BMI) and diastolic blood pressure percentiles (DBP) (β = −5.25, 95% CI: −8.88, −1.62 and β = −3.95, 95% CI: −7.02, −0.89, respectively) for all, lower skinfold thickness (β = −4.83, 95% CI: −9.97, 0.31 and higher sit-ups (β = 1.67, 95% CI: −0.17, 3.50) among girls, and lower systolic blood pressure percentiles (SBP) (β = −4.75, 95% CI: −8.99, −0.52) among boys. Greenspace was associated with higher BMI (β = 6.17, 95% CI: 2.47, 9.87), SBP (β = 3.47, 95% CI: −0.05, 6.99), and DBP (β = 4.11, 95% CI: 1.08, 7.13). Conclusions COI indicators were positively associated with youth fitness. Disparities in youth cardiovascular disease risk may be modifiable through community interventions and built environment initiatives targeting select neighborhood factors.

Background Naturally occurring aflatoxins may contribute to poor growth and nutritional statuses in children. Objectives We analyzed the relationship between contemporary and lagged aflatoxin exposure and 1) length-for-age z-score (LAZ); and 2) length, knee-heel length, stunting, weight-for-age z-score (WAZ), and weight-for-length z-score (WLZ). Methods We conducted a longitudinal birth cohort study involving 1675 mother-infant dyads in rural Nepal. Participants were repeatedly visited from pregnancy to 2 years of age (2015–2019). One blood sample was collected during pregnancy and 4 samples were collected from the children at 3, 6, 12, and 18–22 months of age to measure concentrations of aflatoxin B1 (AFB1)-lysine adduct. Multivariate linear fixed-effects and logistic models with generalized estimating equations were used to identify associations between child growth and aflatoxin exposure. Results AFB1-lysine adducts were detected in the majority of children (at 3 months, 80.5%; at 6 months, 75.3%; at 12 months, 81.1%; and at 18–22 months, 85.1%) and in 94.3% of pregnant women. Changes in contemporary ln child AFB1‐lysine adduct concentrations were significantly associated with changes in LAZ (β, −0.05; 95% CI, −0.09 to −0.02; P = 0.003), length (β, −0.19; 95% CI, −0.29 to −0.10; P
