PediaTrac V.3.0 protocol: a prospective, longitudinal study of the development and validation of a web-based tool to measure and track infant and toddler development from birth through 18 months

IntroductionThe need for an efficient, low-cost, comprehensive measure to track infant/toddler development and treatment outcomes is critical, given the importance of early detection and monitoring. This manuscript describes the protocol for the development and testing of a novel measure, PediaTrac, that collects longitudinal, prospective, multidomain data from parents/caregivers to characterise infant/toddler developmental trajectories in term and preterm infants. PediaTrac, a web-based measure, has the potential to become the standard method for monitoring development and detecting risk in infancy and toddlerhood.Methods and analysesUsing a multisite, prospective design, primarcaregivers will complete PediaTrac V.3.0, a survey tool that queries core domains of early development, including feeding/eating/elimination, sleep, sensorimotor, social/sensory information processing, social/communication/cognition and early relational health. Information also will be obtained about demographic, medical and environmental factors and embedded response bias indices are being developed as part of the measure. Using an approach that systematically measures infant/toddler developmental domains during a schedule that corresponds to well-child visits (newborn, 2, 4, 6, 9, 12, 15, 18 months), we will assess 360 caregiver/term infant dyads and 240 caregiver/preterm infant dyads (gestational age <37 weeks). Parameter estimates of our items and latent traits (eg, sensorimotor) will be estimated by theta using item response theory-graded response modelling. Participants also will complete legacy (ie, established) measures of development and caregiver health and functioning, used to provide evidence for construct (discriminant) validity. Predictive validity will be evaluated by examining relationships between the PediaTrac domains and the legacy measures in the total sample and in a subsample of 100 participants who will undergo a neurodevelopmental assessment at 24 months of age.Ethics and disseminationThis investigation has single Institutional Review Board (IRB) multisite approval from the University of Michigan (IRB HUM00151584). The results will be presented at prominent conferences and published in peer-reviewed scientific journals.

Isolated CHDs and neurodevelopmental follow-up using the Bayley Scales of Infant and Toddler Development and the Ages and Stages Questionnaire at 18 and 36 months

Objectives: To compare early neurocognitive development in children born with and without isolated CHD using the Bayley Scales of Infant and Toddler Development (3rd edition) and the Ages and Stages Questionnaire (3rd edition). Methods: Recruitment took place before birth. Women expecting fetuses with and without CHD causing disturbances in the flow of oxygenated blood to the fetal brain were included in a prospective cohort study comprising fetal MRI (previously published) and neurodevelopmental follow-up. We now present the 18- and 36-month neurodevelopmental follow-up using the Bayley Scales according to age and the 6-month-above-age Ages and Stages Questionnaire in 15 children with and 27 children without CHD. Results: Children with CHD had, compared with the children without CHD, an increased risk of scoring ≤ 100 in the Bayley Scales cognition category at 18 and 36 -months; relative risk 1.7 (95% confidence interval (CI): 1.0–2.8) and 3.1 (CI: 1.2–7.5), respectively. They also achieved lower scores in the 6-month-above-age Ages and Stages Questionnaires (24 and 42 months) communication; mean z-score difference −0.72 (CI: −1.4; −0.1) and −1.06 (CI: −1.8; −0.3) and gross motor; mean z-score difference: −0.87 (CI: −1.7; −0.1) and −1.22 (CI: −2.4; −0.02) categories. Conclusions: The children with CHD achieved lower scores in the Bayley Scales cognition category and the Ages and Stages Questionnaire communication and gross motor categories possibly indicative of early neurodevelopmental deficiencies. We recommend early screening and monitoring for neurodevelopmental delays in children with CHD in order to improve further neurodevelopment and educational achievements.

Neurodevelopmental assessment of infants born to mothers with hypertensive disorder of pregnancy at six months of age

Infant neurodevelopment is a complex process which may be affected by different events during pregnancy, such as hypertensive disorders of pregnancy (HDP). We conducted a prospective cohort study to compare the prevalence of neurodevelopmental disorders in infants born to mothers with and without HDP at six months of age. Participants attended the Health Observatory of Instituto de Desarrollo e Investigaciones Pediátricas “Prof. Dr. Fernando E. Viteri” during 2018 and 2019. Infant neurodevelopment was assessed with the Bayley Scales of Infant and Toddler Development—Third Edition (Bayley-III). Data were analyzed using Chi-square, Student’s t-test and Mann–Whitney test. Of the 132 participating infants, 68 and 64 were born to mothers with and without HDP, respectively. At six months, the prevalence of risk of neurodevelopmental delay was significantly higher in infants born to mothers with than without HDP (27.9% vs. 9.4%; p = 0.008) (odds ratio, 3.71; 95% confidence interval, 1.30; 12.28). In conclusion, infants born to mothers with HDP had three times increased risk of neurodevelopmental delay at six months of age.

Pre-Toddler Development Examination Screening (KPSP) at Posyandu Jatikalang Village, Prambon District, Sidoarjo Regency

Delay in the development of children under five occurs around 10% in children aged <5 years. The purpose of community service activities is to carry out checks on child development and assess child development using the Pre-Screening Questionnaire for Child Development. The method uses interviews and observations. The study population is all mothers who have children under five, the sample is all children aged <5 years who come to the posyandu. The results show that the age period of children 3 - 72 months, the majority of children aged 15 months are 11 children (14%), 6 months of age are 10 children (12.9%), 30 months of age are 9 children (11.6%), age 3 month totaling 8 children (10.3%). While children with appropriate development are 65 children (83%), development children are doubting 12 children (15.4%) and children with deviant development are 1 child (1.3%). Thus children who have doubts and deviant developments need to do counseling and stimulation interventions to improve children's optimal developmental abilities.

Early Regulatory Skills and Social Communication Development in Infants with Down Syndrome

Children with Down syndrome (DS) demonstrate substantial variability in communication and language outcomes. One potential source of variability in this skill area may be early regulatory function. Characterizing the early link between regulatory function and early social communication may benefit infants with DS at risk of difficulties with social communication and language skill acquisition. Forty-three infants with DS were assessed at two time points, six months apart. At Time 1, the average chronological age was 9.0 months (SD = 3.9) and caregivers completed the Infant Behavior Questionnaire-Revised (IBQ-R) to assess regulatory function. Six months later, caregivers rated infant communication at the second visit using the Communication and Symbolic Behavior Scales Infant Toddler Checklist (CSBS-ITC). Infant developmental level was assessed at both visits using the Bayley Scales of Infant and Toddler Development, Third Edition and caregivers reported on developmental history and biomedical comorbidities. Infant regulatory function at Time 1 predicted social communication outcomes at Time 2, six months later. Findings from this study suggest that elevated risk for pronounced communication challenges may be detectable as early as infancy in DS.
