RESUMO

This study tested phenotypic and biometric associations between physical and cognitive catch-up growth in a community sample of twins (n = 1285, 51.8% female, 89.3% White). Height and weight were measured at up to 17 time points between birth and 15 years, and cognitive ability was assessed at up to 16 time points between 3 months and 15 years. Weight and length at birth were positively associated with cognitive abilities in infancy and adolescence (r's = .16-.51). More rapid weight catch-up growth was associated with slower, steadier cognitive catch-up growth. Shared and nonshared environmental factors accounted for positive associations between physical size at birth and cognitive outcomes. Findings highlight the role of prenatal environmental experiences in physical and cognitive co-development.

RESUMO

BACKGROUND: Children in low-resource areas experience nutritional and infection challenges delaying growth and cognitive development. OBJECTIVES: Our goal was to assess for associations of circulating biomarkers related to nutrition and inflammation, with growth and developmental outcomes among children in a birth cohort in a resource-poor area in rural Tanzania. METHODS: We assessed data from 1,120 children participating in the Early Life Interventions for Childhood Growth and Development in Tanzania (ELICIT) study. At age 12 and 18 mo, participants had blood tests performed for hemoglobin, collagen-X, insulin-like growth factor-1 (IGF-1), fibroblast growth factor-21 (FGF21), thyroglobulin, ferritin, soluble transferrin receptor (sTFR), retinol binding protein-4 (RBP4), C-reactive protein (CRP), α1-acid glycoprotein (AGP), and CD14. At 18 mo, participants had anthropometry measured and converted to z-scores for length-for-age (LAZ), weight-for-age (WAZ) and head-circumference-for-age (HCZ) and had the Malawi Developmental Assessment Tool (MDAT) performed to evaluate cognitive development. We performed linear regression assessing biomarkers (predictor variable) on anthropometry and MDAT scores (dependent variables), adjusted for sex, socioeconomic status, and baseline values. RESULTS: There was a high degree of intrafactor correlation between 12 and 18 mo and interfactor correlation between biomarkers. IGF-1 and sTFR were positively and FGF21 and ferritin negatively associated with LAZ at 18 mo, whereas collagen-X and CD14 were additionally associated with recent linear growth. Only markers predominantly related to nutrition were consistently linked with WAZ at 18 mo, while RBP4 and AGP were additionally associated with recent change in WAZ. IGF-1 was positively and thyroglobulin, RBP4, and CD14 negatively linked to MDAT scores. IGF-1 was the only factor linked to both 18-mo LAZ and MDAT. CONCLUSIONS: Individual biomarkers were consistently linked to growth and cognitive outcomes, providing support for relationships between nutrition and inflammation in early child development. Further research is needed to assess overlaps in how biomarker-related processes interact with both growth and learning. REGISTERED AT CLINICALTRIALS.GOV: NCT03268902.

RESUMO

Owing to high rates of prenatal complications, twins are, on average, substantially smaller than population norms on physical measurements including height, weight, and head circumference at birth. By early childhood, twins are physically average. This study is the first to explore the process of catch-up growth by fitting asymptotic growth models to age-standardized height, weight, and head circumference measurements in a community sample of twins (n = 1281, 52.3% female) followed at up to 17 time points from birth to 15 years. Catch-up growth was rapid over the first year and plateaued around the population mean by early childhood. Shared environmental factors accounted for the majority of individual differences in initial physical size (57.7-65.5%), whereas additive genetic factors accounted for the majority of individual differences in the upper asymptotes of height, weight, and head circumference (73.4-92.6%). Both additive genetic and shared environmental factors were associated with variance in how quickly twins caught up. Gestational age and family SES emerged as important environmental correlates of physical catch-up growth.

RESUMO

Cognitive development in children begins with brain development. Early life exposures may both positively and negatively influence cognitive development in children. Infants, toddlers, and children learn best in secure, nurturing environments and when attachment to a consistent caregiver is present. Pediatricians can screen for both social determinants of health and developmental milestones at office visits to address barriers to care and promote positive cognitive and learning outcomes. Pediatricians may model developmental stimulation during office visits to talk with an infant/child, asking questions of a child, singing and pointing to pictures in books, and modeling responsive listening. Pediatricians may support caregivers to talk with their children, read to their children, and avoid/reduce screen time. Pediatricians can help point caregivers to resources for parent training, Head Start, and quality preschool programs. School readiness has both pre-academic and socioemotional components and can have long-term effects on a child's school success, health, and quality of life. School readiness depends on both the child and the caregiver being ready for school, taking into account caregiver and child health and mental health and child cognitive development.

RESUMO

BACKGROUND: In population-based growth surveys in sub-Saharan Africa, boys have higher rates of growth failure than girls. OBJECTIVES: Our goal was to assess for the presence, timing, and potential etiology of sex-based differences in length-for-age z score (LAZ), weight-for-age z score (WAZ), and head circumference-for-age z score (HCZ) in a birth cohort in rural Tanzania. METHODS: We performed a secondary analysis of randomized controlled trial data on 1084 children followed from age <2 wk to 18 mo, assessing anthropometry (measured every 3 mo), illness (hospitalization and monthly maternal report of symptoms), and feeding [monthly maternal report of exclusive breastfeeding (EBF) and complementary solids and liquids (CSLs)]. We used linear regression to assess sex differences in LAZ, WAZ, and HCZ over time. RESULTS: Although male and female infants had similar anthropometry measures at study entry, males exhibited poorer growth through 6 mo (e.g., 3-mo mean LAZ: males -0.94, females -0.74, P < 0.01; 3-mo mean WAZ: males -0.63, females -0.48, P < 0.05), without significant worsening from 6 to 18 mo. Males had lower HCZ only at 9 mo. In evaluating possible etiologies, mediation analysis failed to identify illness or hospitalization as mediators of poorer growth among males, although at age 3 mo, males with recently reported illness exhibited greater decline in WAZ than females with illness (ΔWAZ: males -0.24, females 0.03, heterogeneity test P = 0.01). Differences in EBF and introduction of CSL did not explain the sex-based growth outcomes. CONCLUSIONS: In longitudinal analysis, males exhibited more severe growth failure by 3 mo than girls and did not exhibit catchup growth between 6 and 18 mo. Reported symptoms of illness and early introduction of CSL did not appear to be mediators of these sex-based differences, although likely not all sickness was captured by monthly maternal report. Given the early nature of these deficits, LAZ and WAZ measures at 6 mo may be good outcomes for intervention studies targeting improvements in early childhood growth and thriving.

RESUMO

BACKGROUND: Stunting among children in low-resource settings is associated with enteric pathogen carriage and micronutrient deficiencies. Our goal was to test whether administration of scheduled antimicrobials and daily nicotinamide improved linear growth in a region with a high prevalence of stunting and enteric pathogen carriage. METHODS AND FINDINGS: We performed a randomized, 2 × 2 factorial, double-blind, placebo-controlled trial in the area around Haydom, Tanzania. Mother-child dyads were enrolled by age 14 days and followed with monthly home visits and every 3-month anthropometry assessments through 18 months. Those randomized to the antimicrobial arm received 2 medications (versus corresponding placebos): azithromycin (single dose of 20 mg/kg) at months 6, 9, 12, and 15 and nitazoxanide (3-day course of 100 mg twice daily) at months 12 and 15. Those randomized to nicotinamide arm received daily nicotinamide to the mother (250 mg pills months 0 to 6) and to the child (100 mg sachets months 6 to 18). Primary outcome was length-for-age z-score (LAZ) at 18 months in the modified intention-to-treat group. Between September 5, 2017 and August 31, 2018, 1,188 children were randomized, of whom 1,084 (n = 277 placebo/placebo, 273 antimicrobial/placebo, 274 placebo/nicotinamide, and 260 antimicrobial/nicotinamide) were included in the modified intention-to-treat analysis. The study was suspended for a 3-month period by the Tanzanian National Institute for Medical Research (NIMR) because of concerns related to the timing of laboratory testing and the total number of serious adverse events (SAEs); this resulted in some participants receiving their final study assessment late. There was a high prevalence of stunting overall (533/1,084, 49.2%). Mean 18-month LAZ did not differ between groups for either intervention (mean LAZ with 95% confidence interval [CI]: antimicrobial: -2.05 CI -2.13, -1.96, placebo: -2.05 CI -2.14, -1.97; mean difference: 0.01 CI -0.13, 0.11, p = 0.91; nicotinamide: -2.06 CI -2.13, -1.95, placebo: -2.04 CI -2.14, -1.98, mean difference 0.03 CI -0.15, 0.09, p = 0.66). There was no difference in LAZ for either intervention after adjusting for possible confounders (baseline LAZ, age in days at 18-month measurement, ward, hospital birth, birth month, years of maternal education, socioeconomic status (SES) quartile category, sex, whether the mother was a member of the Datoga tribe, and mother's height). Adverse events (AEs) and SAEs were overall similar between treatment groups for both the nicotinamide and antimicrobial interventions. Key limitations include the absence of laboratory measures of pathogen carriage and nicotinamide metabolism to provide context for the negative findings. CONCLUSIONS: In this study, we observed that neither scheduled administration of azithromycin and nitazoxanide nor daily provision of nicotinamide was associated with improved growth in this resource-poor setting with a high force of enteric infections. Further research remains critical to identify interventions toward improved early childhood growth in challenging conditions. TRIAL REGISTRATION: ClinicalTrials.gov NCT03268902.

RESUMO

OBJECTIVE: Executive functions such as working memory and cognitive flexibility are key to lifelong learning. Our hypothesis was that children born low birthweight (LBW), defined as weight < 2,500 g, would have lower cognitive outcomes than those born normal weight, and children with poor executive functioning would be at risk for poor academic outcomes. STUDY DESIGN: We evaluated data from 12,656 children followed prospectively in the Early Childhood Longitudinal Study, Kindergarten Class 2010-2011, assessing outcomes from kindergarten, first grade, and second grade. Multivariable linear and logistic regressions were run evaluating the relationship between birthweight and cognitive outcomes, and the odds of infants with poor executive functioning having poor academic outcomes. RESULTS: Compared with children with normal birthweight, those born LBW had lower mean z-scores for academic and directly assessed executive functions from kindergarten through second grade. LBW children were at an increased risk of scoring in the bottom 20% of children at all time points: second-grade reading odds ratio (OR) = 1.60 (95% confidence interval [CI:] 1.23-2.09), math OR = 1.49 (95% CI: 1.21-1.84), science OR = 1.41 (95% CI: 1.11-1.81), cognitive flexibility OR = 1.61 (95% CI: 1.27-2.02), and working memory OR = 1.40 (95% CI: 1.10-1.77). CONCLUSION: LBW infants remain at risk of poor cognitive outcomes in second grade. Early difficulties with executive functioning can increase the risk of a child's academic performance years later.

RESUMO

BACKGROUND: Approximately 66% of children under the age of 5 in Sub-Saharan African countries do not reach their full cognitive potential, the highest percentage in the world. Because the majority of studies investigating child cognitive development have been conducted in high-income countries (HICs), there is limited knowledge regarding the determinants of child development in low- and middle-income countries (LMICs). METHODS: This analysis includes 401 mother-child dyads from the South Africa and Tanzania sites of the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) longitudinal birth cohort study. We investigated the effect of psychosocial and environmental determinants on child cognitive development measured by the Wechsler Preschool Primary Scales of Intelligence (WPPSI) at 5 years of age using multivariable linear regression. RESULTS: Socioeconomic status was most strongly associated with child cognitive development (WPSSI Score Difference (SD):14.27, 95% CI:1.96, 26.59). Modest associations between the organization of the home environment and its opportunities for cognitive stimulation and child cognitive development were also found (SD: 3.08, 95% CI: 0.65, 5.52 and SD: 3.18, 95% CI: 0.59, 5.76, respectively). CONCLUSION: This study shows a stronger association with child cognitive development at 5 years of age for socioeconomic status compared to more proximal measures of psychosocial and environmental determinants. A better understanding of the role of these factors is needed to inform interventions aiming to alleviate the burden of compromised cognitive development for children in LMICs.

RESUMO

BACKGROUND: Child cognitive development is influenced by early-life insults and protective factors. To what extent these factors have a long-term legacy on child development and hence fulfillment of cognitive potential is unknown. OBJECTIVE: The aim of this study was to examine the relation between early-life factors (birth to 2 y) and cognitive development at 5 y. METHODS: Observational follow-up visits were made of children at 5 y, previously enrolled in the community-based MAL-ED longitudinal cohort. The burden of enteropathogens, prevalence of illness, complementary diet intake, micronutrient status, and household and maternal factors from birth to 2 y were extensively measured and their relation with the Wechsler Preschool Primary Scales of Intelligence at 5 y was examined through use of linear regression. RESULTS: Cognitive T-scores from 813 of 1198 (68%) children were examined and 5 variables had significant associations in multivariable models: mean child plasma transferrin receptor concentration (ß: -1.81, 95% CI: -2.75, -0.86), number of years of maternal education (ß: 0.27, 95% CI: 0.08, 0.45), maternal cognitive reasoning score (ß: 0.09, 95% CI: 0.03, 0.15), household assets score (ß: 0.64, 95% CI: 0.24, 1.04), and HOME child cleanliness factor (ß: 0.60, 95% CI: 0.05, 1.15). In multivariable models, the mean rate of enteropathogen detections, burden of illness, and complementary food intakes between birth and 2 y were not significantly related to 5-y cognition. CONCLUSIONS: A nurturing home context in terms of a healthy/clean environment and household wealth, provision of adequate micronutrients, maternal education, and cognitive reasoning have a strong and persistent influence on child cognitive development. Efforts addressing aspects of poverty around micronutrient status, nurturing caregiving, and enabling home environments are likely to have lasting positive impacts on child cognitive development.

RESUMO

Food insecurity has been linked with lifestyle and metabolic health differences in varying populations. We sought to assess how food insecurity may have been associated with prediabetes and dietary differences in a relatively young subset of U.S. adults. We examined data from the United States National Health and Nutrition Examination Survey (2003-2014) participants aged 20-39 with complete data regarding food insecurity and metabolic laboratory assessment. We also assessed macronutrient intake and Supplemental Nutrition Assistance Program (SNAP) usage. All logistic regression models controlled for age, sex, and household income. Among 3684 included participants, food insecurity had 19.12% (95% confidence interval [95%CI]: 16.16, 22.08) prevalence. Food-insecure participants had prediabetes/diabetes prevalence of 37.36% (95%CI: 30.47, 44.25) and higher odds of having prediabetes/diabetes (adjusted odds ratio [aOR] = 1.36, 95%CI: 1.00, 1.85). Food-insecure adults has significantly different macronutrient intake: higher carbohydrates (p = 0.02), less protein (p = 0.01), and less total fat (p = 0.04) consumption. Food-insecure adults who used SNAP (compared to food-insecure adults who did not use SNAP) had higher odds of having metabolic syndrome (ATP-III MetS) (aOR = 2.56, 95%CI: 1.27, 5.22). We found that food insecurity was relatively prevalent in this subset of younger U.S. adults. We showed that food-insecure participants had increased prevalence and odds of prediabetes. These associations were also correlated with dietary differences.

RESUMO

Although many studies around the world hope to measure or improve developmental progress in children to promote community flourishing and productivity, growth is sometimes used as a surrogate because cognitive skills are more difficult to measure. Our objective was to assess how childhood measures of anthropometry correlate with measures of child development in low-income settings with high prevalence of poor nutrition and enteric disease, to inform studies considering growth outcomes in the absence of direct child developmental skill assessment. Children from the MAL-ED study were followed from birth to 24 months of age in field sites in 8 low- and middle-income countries across 3 continents. Monthly weight, length, and head circumference measurements were performed. At 24 months, the Bayley Scales of Infant and Toddler Development was administered. We correlated cognitive measures at 24 months with anthropometric measurements from birth to 2 years comparing 3 constructs: absolute attained monthly measures, summative difference in measures from the mean growth curve, and rate of change in measures. Growth faltering at multiple time periods is related to Bayley cognitive outcomes at 24 months. Birthweight, overall growth by 18-24 months, and rate of growth in the 6- to 18-month period were most associated with 24-month developmental scores. In this study, head circumference measurements, compared with length, was more closely linked to cognitive scores at 24 months. Notably, all studies between growth and cognitive outcomes exhibited low r2 values (0.001-0.049). Anthropometric measures, particularly head circumference, were related to cognitive development, although explaining a low percent of variance. When feasible, direct measures of child development may be more useful.

RESUMO

BACKGROUND: Spasmodic dysphonia is a focal dystonia characterized by involuntary spasms in the laryngeal muscles that occur selectively during speaking. Although hereditary trends have been reported in up to 16% of patients, the causative etiology of spasmodic dysphonia is unclear, and the influences of various phenotypes and genotypes on disorder pathophysiology are poorly understood. In this study, we examined structural alterations in cortical gray matter and white matter integrity in relationship to different phenotypes and putative genotypes of spasmodic dysphonia to elucidate the structural component of its complex pathophysiology. METHODS: Eighty-nine patients with spasmodic dysphonia underwent high-resolution magnetic resonance imaging and diffusion-weighted imaging to examine cortical thickness and white matter fractional anisotropy in adductor versus abductor forms (distinct phenotypes) and in sporadic versus familial cases (distinct genotypes). RESULTS: Phenotype-specific abnormalities were localized in the left sensorimotor cortex and angular gyrus and the white matter bundle of the right superior corona radiata. Genotype-specific alterations were found in the left superior temporal gyrus, supplementary motor area, and the arcuate portion of the left superior longitudinal fasciculus. CONCLUSIONS: Our findings suggest that phenotypic differences in spasmodic dysphonia arise at the level of the primary and associative areas of motor control, whereas genotype-related pathophysiological mechanisms may be associated with dysfunction of regions regulating phonological and sensory processing. Identification of structural alterations specific to disorder phenotype and putative genotype provides an important step toward future delineation of imaging markers and potential targets for novel therapeutic interventions for spasmodic dysphonia. © 2017 International Parkinson and Movement Disorder Society.

RESUMO

Temporal trends in the epidemic of childhood obesity have been paralleled by increases in the consumption of sugar-sweetened beverages (SSB) during childhood. Consumption has increased dramatically over the past several decades in all age ranges, with some moderation over the past 10 years. Evidence from cross-sectional, longitudinal, and interventional studies supports links between SSB consumption in childhood and unhealthy weight gain, as well as other untoward health outcomes. These data have stimulated public health efforts to curtail consumption as a means of improving childhood weight status and related health outcomes. Reducing ready access to SSBs, changing the message environment to which children are exposed, and replacing SSBs with healthier beverages have had moderate success in decreasing SSB consumption and curbing unhealthy weight gain.

RESUMO

• On the basis of observational studies (level C), preterm birth is a leading cause of neurodevelopmental disabilities in children, and the degree of neurodevelopmental disability is inversely correlated with gestational age at birth. When comparing performance of preterm children to developmental norms, "corrected age" or age from due date rather than birth date should be used for the first 24 to 36 months. • On the basis of observational studies (level C), clinicians should pay specific attention to sensory function in children born preterm because the incidence of visual and hearing impairments is higher in preterm than term children. Due to the elevated risk of cognitive and behavioral disabilities, clinicians caring for children born preterm should be vigilant when performing developmental assessments to improve outcomes. • On the basis of observational studies (level C), early identification of developmental delays allows for referral to therapeutic services, and children referred for early intervention are more likely to make gains in developmental milestones.

RESUMO

The Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) cohort in the study's Fortaleza, Brazil, catchment area has a population of approximately 82 300 inhabitants. Most of the households (87%) have access to clean water, 98% have electricity, and 69% have access to improved toilet/sanitation. Most childbirths occur at the hospital, and the under-5 mortality rate is 20 per 1000 live births. The MAL-ED case-control study population, identified through the Institute for the Promotion of Nutrition and Human Development (IPREDE), serves 600 000 inhabitants from areas totaling about 42% of the city of Fortaleza. IPREDE receives referrals from throughout the state of Ceará for infant nutrition, and provides services including teaching activities and the training of graduate students and health professionals, while supporting research projects on child nutrition and health. In this article, we describe the geographic, demographic, socioeconomic, anthropometric, and environmental status of the MAL-ED cohort and case-control study populations in Fortaleza, Brazil.

RESUMO

More epidemiological data are needed on risk and protective factors for child development. In The Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) cohort study, we assessed child development in a harmonious manner across 8 sites in Bangladesh, Brazil, India, Nepal, Pakistan, Peru, South Africa, and Tanzania. From birth to 24 months, development and language acquisition were assessed via the Bayley Scales of Infant and Toddler Development and a modified MacArthur Communicative Development Inventory. Other measures were infant temperament, the child's environment, maternal psychological adjustment, and maternal reasoning abilities. We developed standard operating procedures and used multiple techniques to ensure appropriate adaptation and quality assurance across the sites. Test adaptation required significant time and human resources but is essential for data quality; funders should support this step in future studies. At the end of this study, we will have a portfolio of culturally adapted instruments for child development studies with examination of psychometric properties of each tool used.

RESUMO

BACKGROUND: An estimated one-third of children younger than 5 years in low- and middle-income countries fail to meet their full developmental potential. The first year of life is a period of critical brain development and is also when most of the morbidity from infection is suffered. We aimed to determine if clinical and biological markers of inflammation in the first year of life predict cognitive, language, and motor outcomes in children living in an urban slum in Bangladesh. METHODS: Children living in Dhaka, Bangladesh were observed from birth until 24 months of age. Febrile illness was used as a clinical marker of inflammation and elevated concentrations of inflammation-related cytokines (IL-1ß, IL-6, TNF-α, IL-4, IL-10) in sera collected from a subset of the cohort (N = 127) at 6 months of age were used as biomarkers of inflammation. Psychologists assessed cognitive, language, and motor development using a culturally adapted version of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) at 12 (N = 398) and 24 months of age (N = 210). We tested for the ability of febrile illness and elevated cytokine levels to predict developmental outcomes, independent of known predictors of stunting, family income, and maternal education. RESULTS: Every additional 10 days of fever was associated with a 1.9 decrease in language composite score and a 2.1 decrease in motor composite score (p = 0.005 and 0.0002, respectively). Elevated levels of the pro-inflammatory cytokines IL-1ß (> 7.06 pg/mL) and IL-6 (> 10.52 pg/mL) were significantly associated with a 4.9 and 4.3 decrease in motor score, respectively. Conversely, an elevated level of the Th-2 cytokine IL-4 (> 0.70 pg/mL) was associated with a 3.6 increase in cognitive score (all p < 0.05). CONCLUSIONS: Clinical and biological markers of inflammation in the first year of life were significantly associated with poor neurodevelopmental outcomes. Conversely, a Th2-like response was associated with a better outcome. These findings suggest that markers of inflammation could serve as prognostic indicators and potentially lead to immune-based therapies to prevent developmental delays in at-risk children.

RESUMO

BACKGROUND: Previous studies of quality of life (QOL), mood, and behavior in muscular dystrophy focus on caregiver perceptions. This cross-sectional study aims to determine the prevalence of clinically significant mood and behavior problems by both patient and caregiver report and assess relationship between mood/behavior and QOL. METHODS: Forty-one patients with dystrophinopathies (Duchenne muscular dystrophy [DMD] and Becker muscular dystrophy [BMD]) were recruited through the University of Virginia Neuromuscular Clinic. Each patient and caregiver dyad completed questionnaires, including the Behavior Assessment System for Children, 2nd Edition (BASC-2); the Pediatric Quality of Life Inventory for DMD (PedsQL-DMD); Children's Depression Inventory, 2nd Edition; and Screen for Child Anxiety Related Disorders. RESULTS: Persons with dystrophinopathies rated most of their behavior and adaptive skills similarly to the general population. Sixty-four percent of parent assessments rated clinically significant problems on the BASC-2. Worse BASC-2 scores for self- and parent assessments correlated with lower (worse) scores in the Worry and Communication PedsQL domains. Patient-reported QOL scores were higher than parent-reported scores in each domain except Worry. CONCLUSIONS: Individuals with DMD/BMD rate their adaptive skills, behavioral symptoms, externalizing and internalizing problems, and school problems more positively than parents/caregivers. Obtaining self-report data is a worthwhile endeavor that can add value to intervention planning, with the ultimate goal of optimizing QOL.

RESUMO

OBJECTIVE: To determine whether preterm birth of 32-36 6/7 weeks gestation affected school performance from kindergarten through fifth grade. STUDY DESIGN: We assessed 14350 term infants and 1195 32-36 6/7 weeks gestation infants followed in the Early Childhood Longitudinal Study Kindergarten 2011 cohort for classroom performance in kindergarten-fifth grade. Multivariable regression was performed for comparisons, and data were weighted to be representative of the US population. RESULTS: Children born 35-36 6/7 weeks gestation had no significant difference in their academic scores or performance, while 32-34 6/7 weeks' children had lower academic scores and teacher performance scores when compared to term children. Children born between 32 and 36 6/7 weeks gestation had higher odds of individualized education plan needs and had learning disability diagnoses compared to term children. CONCLUSIONS: Children born between 32 and 34 6/7 weeks gestation have poor school performance compared to term children. Children born between 32 and 36 6/7 weeks gestation are at risk for learning disabilities and likely benefit from continued support and services to improve achievement throughout school.

RESUMO

BACKGROUND: The majority of the estimated 50 to 100 million children living with disability worldwide reside in low- or middle-income countries. As families migrate to avoid humanitarian crises, children with developmental disability and delay warrant particular attention in refugee and international health settings. During transitions, medical documentation may be lost and diagnoses may not be fully understood, contributing to the challenges of determining etiologies of motor impairment. METHODS: Of the first 100 refugee children who were referred to the Child Development Clinic, we identified a subset of children referred for motor impairment or cerebral palsy. Data on their presentation, diagnoses following evaluation, and therapeutic services required was collected by retrospective chart review. RESULTS: Twenty children were referred for motor impairment and cerebral palsy. Average age was 8.9 years; 45% were female. Eight children were eventually diagnosed with cerebral palsy, and 12 had alternate or inconclusive diagnoses. Microcephaly was more common in children diagnosed with cerebral palsy. CONCLUSIONS: The frequent differences between referral and final diagnoses in refugee children referred for cerebral palsy highlights the need for pediatricians' careful examination and diagnostic reasoning upon initial presentation.
