Factors Associated with Self-regulation in a Nationally Representative Sample of Children Ages 3-5 Years: United States, 2016.

OBJECTIVE: The aim of the present study was to describe self-regulation (the ability to influence or control one's thoughts or behavior in response to situational demands and social norms) in children ages 3-5 years using a nationally representative sample and examine risk and protective factors to identify opportunities to support children and families. METHODS: Using a cross-sectional design, we examined data from a parent-reported pilot measure of self-regulation from the 2016 National Survey of Children's Health (NSCH). We compared U.S. children aged 3-5 years who were described by parents as "on track" with self-regulation development with children who were not. In addition, we described how health care and developmental services, community, family, and child health and development factors are associated with children's self-regulation. RESULTS: The majority of children (4 of 5) were described by their parents to be developmentally on track with self-regulation. Compared to children described as not on track, children described as on track more often lived in financially and socially advantaged environments and less often experienced family adversity. They also had other positive health and development indicators, whether or not they were receiving developmental services. However, only half of children not on track received developmental surveillance, and only 1 in 4 children described as not on track received educational, mental health, or developmental services. CONCLUSION: The findings are a step towards using self-regulation as an indicator of healthy child development and as a potential strategy to identify groups of children who may need additional support.

Health and Development at Age 19-24 Months of 19 Children Who Were Born with Microcephaly and Laboratory Evidence of Congenital Zika Virus Infection During the 2015 Zika Virus Outbreak - Brazil, 2017.

In November 2015, the Brazilian Ministry of Health (MOH) declared the Zika virus outbreak a public health emergency after an increase in microcephaly cases was reported in the northeast region of the country (1). During 2015-2016, 15 states in Brazil with laboratory-confirmed Zika virus transmission reported an increase in birth prevalence of microcephaly (2.8 cases per 10,000 live births), significantly exceeding prevalence in four states without confirmed transmission (0.6 per 10,000) (2). Although children with microcephaly and laboratory evidence of Zika virus infection have been described in early infancy (3), their subsequent health and development have not been well characterized, constraining planning for the care and support of these children and their families. The Brazilian MOH, the State Health Secretariat of Paraíba, and CDC collaborated on a follow-up investigation of the health and development of children in northeastern Brazil who were reported to national surveillance with microcephaly at birth. Nineteen children with microcephaly at birth and laboratory evidence of Zika virus infection were assessed through clinical evaluations, caregiver interviews, and review of medical records. At follow-up (ages 19-24 months), most of these children had severe motor impairment, seizure disorders, hearing and vision abnormalities, and sleep difficulties. Children with microcephaly and laboratory evidence of Zika virus infection have severe functional limitations and will require specialized care from clinicians and caregivers as they age.

Etiology of Prelingual Hearing Loss in the Universal Newborn Hearing Screening Era: A Scoping Review.

OBJECTIVE: To conduct a scoping review on etiologic investigation of prelingual hearing loss among children <2 years of age in the era of universal newborn hearing screening (UNHS). DATA SOURCES: PubMed, Embase, PsycInfo, CINAHL, and Cochrane Library databases. REVIEW METHODS: We searched for articles published from January 1, 1998, to February 19, 2020. We reviewed studies that (1) included children identified with either congenital or delayed-onset hearing loss before 2 years of age among cohorts who had undergone UNHS and (2) investigated ≥1 etiologies of hearing loss. We defined hearing loss as congenital when confirmed after UNHS failure and as delayed onset when diagnosed after ≥1 assessments with normal hearing. RESULTS: Among 2069 unique citations, 115 studies met criteria for full-text assessment, and 20 met our inclusion criteria. Six studies tested children diagnosed with hearing loss for genetic etiology, 9 for congenital cytomegalovirus (CMV) infection, and 5 for both. Among 1787 children with congenital hearing loss and etiologic investigation, 933 (52.2%) were tested for genetic mutations and 1021 (57.1%) for congenital CMV infection. The proportion of congenital hearing loss cases attributable to genetic etiology ranged between 7.7% and 83.3% and to congenital CMV infection between 0.0% and 32.0%. CONCLUSION: Data are lacking on the identification and etiology of delayed-onset hearing loss in children <2 years of age in the UNHS era. The proportion of congenital hearing loss cases attributable to genetic etiologies and congenital CMV infection appears to vary widely.

Kindergarten Readiness in Children Who Are Deaf or Hard of Hearing Who Received Early Intervention.

BACKGROUND: Children who are deaf or hard of hearing (D/HH) have improved language outcomes when enrolled in early intervention (EI) before the age of 6 months. Little is understood about the long-term impact of EI on outcomes of kindergarten readiness (K-readiness). The study objective was to evaluate the impact of EI before the age of 6 months (early) versus after 6 months (later) on K-readiness in children who are D/HH. METHODS: In this study, we leveraged data from the Ohio Early Hearing Detection and Intervention Data Linkage Project, which linked records of 1746 infants identified with permanent hearing loss born from 2008 to 2014 across 3 Ohio state agencies; 417 had kindergarten records. The Kindergarten Readiness Assessment was used to identify children as ready for kindergarten; 385 had Kindergarten Readiness Assessment scores available. Multiple logistic regression was used to investigate the relationship between K-readiness and early EI entry while controlling for confounders (eg, hearing loss severity and disability status). RESULTS: Children who were D/HH and entered EI early (n = 222; 57.7% of the cohort) were more likely to demonstrate K-readiness compared with children who entered EI later (33.8% vs 20.9%; P = .005). Children who entered early had similar levels of K-readiness as all Ohio students (39.9%). After controlling for confounders, children who entered EI early were more likely to be ready for kindergarten compared with children who entered later (odds ratio: 2.02; 95% confidence interval 1.18-3.45). CONCLUSIONS: These findings support the sustained effects of early EI services on early educational outcomes among children who are D/HH. EI entry before the age of 6 months may establish healthy trajectories of early childhood development, reducing the risk for later academic struggles.

Adapting the Ages and Stages Questionnaire to Identify and Quantify Development Among Children With Evidence of Zika Infection.

This article describes novel methods of applying the Ages and Stages Questionnaire-3rd edition (ASQ-3) to assess and quantify developmental delay among children following the 2015-2016 Zika virus outbreak in Brazil. Many of the children with Zika virus infection were expected to have severe developmental delay. However, administering the ASQ-3 to caregivers of these children according to standard protocol would have screened for the overall presence of delay but not the severity of delay. We adopted an amended protocol for administration of the ASQ-3 to quantify the developmental functioning of children severely affected by Zika virus infection in this investigation. Protocols for administering the ASQ-3 among this population were drafted in consultation with developmental measurement experts and are presented here. Specific developmental estimates are discussed, including developmental age equivalents, developmental quotients, and developmental quotient z scores. The calculations of these estimates are presented with examples in the context of the 2015-2016 Zika virus outbreak and associated microcephaly among prenatally infected children from 2 states in northeastern Brazil. Potential applications of these methods for estimating developmental ability among similar pediatric populations are discussed.

Early Growth Parameters as Predictors of Developmental Delay Among Children Conceived During the 2015-2016 Zika Virus Outbreak in Northeastern Brazil.

BACKGROUND: Identifying infants with congenital infection for early intervention will likely be challenging in future Zika virus outbreaks. We investigated indicators of risk for developmental delay among children born with and without obvious manifestations of congenital Zika virus infection. METHODS: We evaluated 120 children conceived during the 2015-2016 Zika virus outbreak in Paraíba, Brazil. We analyzed data from children at birth; ages 1-7 months and approximately 24 months, using medical records (i.e., anthropometric measurements diagnoses), medical evaluation (i.e., Zika/other laboratory tests, dysmorphic features), and parent report (seizures, developmental delay). We used a Bayesian modeling approach to identify predictors of developmental delay. RESULTS: Head circumference (HC) and length at birth and rates of growth for HC and length at follow-up were consistent across domains of developmental delay; (e.g., for every 1 cm per month decrease in HC growth rate; there was a corresponding decrease in the gross motor z-score). Modeling results indicated that HC and length at birth, and follow-up HC and length rates of growth, were predictive of developmental delay. CONCLUSION: These findings suggest that accurate measurement and frequent monitoring of HC and length, especially in the first few months of life, may be useful for identifying children possibly congenitally exposed to Zika virus who could benefit from early intervention services.

Functional Outcomes among a Cohort of Children in Northeastern Brazil Meeting Criteria for Follow-Up of Congenital Zika Virus Infection.

Following the large outbreak of Zika virus in the Western Hemisphere, many infants have been born with congenital Zika virus infection. It is important to describe the functional outcomes seen with congenital infections to allow for their recognition and appropriate interventions. We evaluated 120 children conceived during the 2015-2016 Zika virus outbreak in Paraíba, Brazil, who were approximately 24 months old, to assess functional outcomes. All children met either anthropometric criteria or laboratory criteria suggestive of possible congenital Zika virus infection. We collected results of previous medical evaluations, interviewed parents, and performed physical examinations and functional assessments, for example, the Hammersmith Infant Neurological Examination (HINE). We compared patterns of neurologic outcomes and developmental delay at age 24 months by whether children met anthropometric or laboratory criteria, or both. Among children meeting both criteria, 60% (26/43) were multiply affected (had severe motor impairment, severe developmental delay, and suboptimal HINE scores), compared with 5% (3/57) meeting only laboratory criteria and none (0/20) meeting only anthropometric criteria. Of the remaining 91 children, 49% (45) had developmental delay, with more severe delay seen in children meeting both criteria. Although children meeting physical and laboratory criteria for potential congenital Zika virus infection were more severely affected, we did identify several children with notable adverse neurologic outcomes and developmental delay with no physical findings but potential laboratory evidence of Zika virus infection. Given this, all children who were potentially exposed in utero to Zika virus should be monitored in early childhood for deficits to allow for early intervention.

Depressive Symptoms and Care Demands Among Primary Caregivers of Young Children with Evidence of Congenital Zika Virus Infection in Brazil.

OBJECTIVE: Evidence suggests that caring for a child with special health care needs can affect many domains of family life, including caregiver mental health. However, few studies have examined these outcomes among families impacted by the Zika virus (ZIKV). This study examines depressive symptom severity and care demands among primary caregivers of children, aged 15 to 26 months, with evidence of congenital Zika virus infection (ZVI). METHODS: A sample of primary caregivers of children with evidence of congenital ZVI in northeastern Brazil (n = 150) reported on depressive symptoms, care demands, and their children's development. Children were categorized into groups according to their developmental delay status. Bivariate analyses were run to test for differences between groups. A path analysis model was used to examine the indirect effects of developmental delay on depressive symptoms through economic challenges and time spent providing health care at home and whether these associations varied by child care support. RESULTS: Compared to primary caregivers of children without developmental delay, primary caregivers of children with developmental delay had higher depression scores (p = 0.002), reported more economic (p < 0.001) and child care (p < 0.001) challenges, and spent more time providing health care at home (p < 0.001). Among primary caregivers who did not have child care support, developmental delay had a significant indirect effect on depressive symptoms through economic challenges but not through time spent providing health care at home. CONCLUSION: For families impacted by the ZIKV outbreak in Brazil, economic and child care challenges may be associated with primary caregiver mental health.
