[PMID: 38579996 DOI: 10.1016/j.envres.2024.118879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 02/22/2024] [Accepted: 04/03/2024] [Indexed: 04/07/2024]
Abstract
BACKGROUND Early life exposure to ambient particulate matter (PM) may negatively affect neurobehavioral development in children, influencing their cognitive, emotional, and social functioning. Here, we report a study on prenatal PM2.5 exposure and neurobehavioral development focusing on different time points in the first years of life. METHODS This study was part of the ENVIRONAGE birth cohort that follows mother-child pairs longitudinally. First, the Neonatal Behavioral Assessment Scale (NBAS) was employed on 88 newborns aged one to two months to assess their autonomic/physiological regulation, motor organisation, state organisation/regulation, and attention/social interaction. Second, our study included 393 children between the ages of four and six years, for which the Strengths and Difficulties Questionnaire (SDQ) was used to assess the children's emotional problems, hyperactivity, conduct problems, peer relationship, and prosocial behaviour. Prenatal PM2.5 exposure was determined using a high-resolution spatial-temporal method based on the maternal address. Multiple linear and multinomial logistic regression models were used to analyse the relationship between prenatal PM2.5 exposure and neurobehavioral development in newborns and children, respectively. RESULTS A 5 μg/m³ increase in first-trimester PM2.5 concentration was associated with lower NBAS range of state cluster scores (-6.11%; 95%CI: -12.00 to -0.23%; p = 0.04) in one-to-two-month-old newborns. No other behavioural clusters nor the reflexes cluster were found to be associated with prenatal PM2.5 exposure. Furthermore, a 5 μg/m³ increment in first-trimester PM2.5 levels was linked with higher odds of a child experiencing peer problems (Odds Ratio (OR) = 3.89; 95%CI: 1.39 to 10.87; p = 0.01) at ages four to six. Additionally, a 5 μg/m³ increase in second-trimester PM2.5 concentration was linked to abnormal prosocial behaviour (OR = 0.49; 95%CI: 0.25 to 0.98; p = 0.04) at four to six years old. No associations were found between in utero PM2.5 exposure and hyperactivity or conduct problems. CONCLUSIONS Our findings suggest that prenatal exposure to PM may impact neurobehavioural development in newborns and preschool children. We identified sensitive time windows during early-to-mid pregnancy, possibly impacting stage changes in newborns and peer problems and prosocial behaviour in children.

Abstract
Assessment of the characteristics of spontaneous movements and behaviour in early infancy helps in estimating developmental outcomes. We introduced the Infant Behaviour Checklist (IBC) and examined the relationship between the behavioural characteristics of low-birth-weight infants and neurodevelopmental outcomes at 6 years of age. The behavioural characteristics during the neonatal (36-43 weeks, adjusted) and early infancy periods (49-60 weeks, adjusted) were assessed in very-low-birth-weight infants. The IBC includes 44 common behaviours. We assessed the appearance of individual behavioural characteristics at each period according to the neurodevelopmental outcome. Of the 143 infants assessed during the neonatal period, 89 had typical development (TD), 30 had intellectual disability (ID), and 24 had autism spectrum disorder (ASD). In 78 infants assessed during early infancy, 40, 21, and 17 had TD, ID, and ASD, respectively. The frequency of appearance of three behaviour-related items was significantly lower in the ID group than in the TD group. The frequency of appearance of three posture- and behaviour-related items was significantly lower, while that of two posture-related items was significantly higher, in the ASD group than in the TD group. Behavioural assessment using the IBC may provide promising clues when considering early intervention for low-birth-weight infants.

Abstract
Background and Objectives: Kangaroo mother care (KMC) benefits preterm infants' health through increasing breastfeeding, but the longitudinal effects of KMC remain unknown. This study investigates the impact of KMC on breastfeeding and health outcomes in Chinese preterm infants. Methods: A longitudinal randomized controlled study was conducted with 79 preterm infant-mother dyads. The KMC group (n = 36) was provided 2.5 hours/day KMC during the neonatal intensive care unit (NICU) hospitalization, while the control group (n = 43) received standard care. Infant's feeding regimens and physical growth were documented daily at NICU. Physical growth and Neonatal Behavioral Neurological Assessment were measured at 40 weeks, 3 months, and 6 months of corrected age (CA). Breastfeeding outcomes were documented at 6 months of CA. Results: Compared with the control group, KMC infants received higher mothers' milk proportion during hospitalization (B = 0.16, confidence interval [CI] = [0.11-0.21]) and less feeding intolerance at discharge (odds ratio [OR] = 0.11, CI = [0.02-0.43]); and higher exclusive breastfeeding proportion (OR = 14.6, CI = [3.5-60.9]) at 6 months CA. KMC infants also had significant increased body weight and body length at hospital discharge; and more increases of body weight, body length, and head circumference in follow-ups. The neurobehavioral score was also higher in the KMC group compared to the control group over time. Conclusions: Longitudinal KMC effects are significant in promoting preterm infants' breastfeeding outcomes, growth, and neurodevelopment. Early initiation of KMC practice is highly recommended to the parent-infant population in Chinese NICUs to promote breastfeeding and developmental outcomes.

Abstract
BACKGROUND Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder typically diagnosed after the second year of life; however, differences in brain structure and function associated with ASD have been ascertained in early infancy. Identifying behavioural markers of ASD risk in early infancy has the potential to facilitate early detection and intervention. OBJECTIVES We examined associations between infant behaviour and adolescent behaviours associated with ASD. METHODS Analyses leveraged data available on 370 participants from the New Bedford Cohort, a sociodemographically diverse prospective birth cohort of children born from 1993 to 1998 to mothers residing near the New Bedford Harbor Superfund site in Massachusetts. Longitudinal assessments were used to examine the associations between behaviours when children were approximately 2 weeks old (measured by the Neonatal Behavioral Assessment Scale [NBAS]), and subsequent maladaptive behaviours associated with ASD at approximately 15 years old [measured by the Behavior Assessment System for Children, 2nd Edition-Teacher Rating Scale (BASC-2 TRS) scores which are standardised to a mean (SD) of 50 (10)]. RESULTS Poorer performance on select individual items and cluster scales of the NBAS was associated with an increase in behaviours associated with ASD in adolescents. Associations were strongest for neonatal measures of self-regulation, response to auditory input, and autonomic nervous system regulation. For example, in covariate-adjusted models, infants with Regulation of State NBAS cluster scores in the lowest tertile (poorest performance) compared to infants with scores in the higher two tertiles had adolescent BASC-2 TRS Developmental Social Disorders T-scores that were 2.9 points higher (95% CI: 0.8, 4.9), indicating more behaviours associated with ASD. CONCLUSION The NBAS is an established and accessible instrument that assesses a broad range of behaviours in very young infants, and may be a useful tool for newborn assessments of developmental risk, including risk of ASD-associated behaviours.

Abstract
BACKGROUND Temperament characteristics are key elements for infants' development. The Infant Behavior Questionnaire - Revised (IBQ-R) is one of the most used measures to assess temperament in infants aged between 3 and 12 months. Its reliability and factor structure have not yet been examined in infants younger than 3 months. AIMS To analyze the reliability of the IBQ-R at 2 weeks and the IBQ-R factor structure from 2 weeks to 12 months of life. METHOD A longitudinal repeated measures design was used. Three hundred mothers completed the IBQ-R when their infants were 2 weeks, and 3, 6 and 12 months. RESULTS At 2 weeks the proportion of "non-applicable" responses was higher in duration of orienting, high intensity pleasure, approach and smiling and laughter scales. The Cronbach's alpha for the IBQ-R dimensions ranged between 0.62 and 0.63 and the McDonald's omega ranged between 0.67 and 0.80, all dimensions exhibited a mean-scale correlation above 0.15, and more than half of the scales revealed a scale-dimension correlation higher than 0.30. The same factor structure was found at 2 weeks, and at 3, 6, and 12 months: surgency/extraversion, p < 0.001, negative affectivity, p < 0.001, and orienting regulation, p = 0.007. CONCLUSIONS The IBQ-R may be applied in the first weeks of life and its factor structure remains stable when applied across different ages throughout infancy.

Abstract
OBJECTIVES To characterize state regulation and behavior of preterm infants after discharge from the neonatal intensive care unit (NICU). METHODS We recruited singleton infants born at ≤35 weeks of gestational age (GA) before NICU discharge. Parents completed surveys at discharge and 1, 3, and 6 months after discharge. Infant medical history was gleaned from the medical record. Surveys captured sociodemographic information and measures of infant state regulation (Baby Pediatric Symptom Checklist [BPSC]) and feeding behaviors. We calculated the median BPSC subscale scores at each time point and the proportion of infants with scores in the problem range (≥3/5). We explored longitudinal and cross-sectional correlates of BPSC scores. RESULTS Fifty families completed the discharge questionnaire, and 42 (84%) completed the 6-month questionnaire. The median GA at birth was 34 weeks (IQR 30.1, 34.4 weeks); the median birth weight was 1930 g (IQR 1460, 2255 g). The median scores were above population norms for irritability and difficulty with routines. Twenty-one infants (40%) had irritability subscale scores in the problem range at 1 month, and 20 (38%) had problem scores on difficulties with routines. Only 9 infants (17%) had problem scores on the inflexibility subscale. Scores in all 3 domains showed different patterns from population norms from 1 to 6 months. BPSC scores were correlated with infant feeding behaviors at 1, 3, and 6 months. CONCLUSION Scores for irritability and difficulty with routines among preterm infants were high compared with population norms and differed from normative values through 6 months after discharge. Preterm infants demonstrate problems with state regulation after NICU discharge that may require directed intervention.

Abstract
We examined the characteristics of spontaneous movements at 9-20 weeks postterm age in very low birth-weight infants who later developed autism spectrum disorder (ASD). We analyzed video recordings of spontaneous movements of 39 children who had no clinical issues [typically developing (TD) group], 21 children who showed developmental delay, and 14 children who were diagnosed with ASD (ASD group) at 6 years of age. Head position in each video frame was classified by visual inspection. The percentage of midline head position (PMHP) and number of changes in head position were calculated. Spontaneous limb movements were quantified using six indices. The values of PMHP were significantly lower in the ASD group than in the TD group. The lower PMHP during early infancy is associated with later development of ASD. Poorer performance in maintaining midline position of the head at this period may distinguish infants who later develop ASD from those who show TD.

Abstract
Neonatal neurobehavioral assessment has become a standardized component of clinical care provided to newborn infants, guiding neonatal clinical care and subsequent access to early interventions and services. Links between neonatal assessment and neurosensory and motor impairments in high-risk infants have been relatively well established. In contrast, the extent to which newborn neurobehavioral assessment might also facilitate the early identification of infants susceptible to socioemotional impairments in early childhood is less well documented. This review examines longitudinal links between the neonatal neurobehavioral assessment, temperament, and socioemotional outcomes in early childhood.

Abstract
Increasing evidence suggests that maternal depression during pregnancy is associated with child behavioral outcomes even after accounting for later maternal depression. The purpose of this study was to examine various mechanisms, including maternal sensitivity, neonatal problems, and concurrent maternal depression, that might explain the association between prenatal maternal depressive symptoms and toddler behavior problems. Young, low income, African American mothers (n = 196) were interviewed during pregnancy and at 24-months postpartum, medical records were collected at the birth, and mother-child interactions were video-recorded at 24 months. Path analyses revealed that the association between prenatal depression and toddler behavior problems was mediated by maternal sensitivity and maternal depressive symptoms at 24 months. No evidence was found for a mediating effect of neonatal problems. Path models examining sex differences suggested that different mediating factors may be important for boys and girls, with boys being particularly susceptible to the effects of maternal sensitivity.

Abstract
BACKGROUND Very preterm (VP) infants are at greater risk for cognitive difficulties that may persist during school-age, adolescence and adulthood. Behavioral assessments report either effortful control (part of executive functions) or emotional reactivity/regulation impairments. AIMS The aim of this study is to examine whether emotional recognition, reactivity, and regulation, as well as effortful control abilities are impaired in very preterm children at 42 months of age, compared with their full-term peers, and to what extent emotional and effortful control difficulties are linked. STUDY DESIGN Children born very preterm (VP; < 29 weeks gestational age, n=41) and full-term (FT) aged-matched children (n=47) participated in a series of specific neuropsychological tests assessing their level of emotional understanding, reactivity and regulation, as well as their attentional and effortful control abilities. RESULTS VP children exhibited higher scores of frustration and fear, and were less accurate in naming facial expressions of emotions than their aged-matched peers. However, VP children and FT children equally performed when asked to choose emotional facial expression in social context, and when we assessed their selective attention skills. VP performed significantly lower than full terms on two tasks of inhibition when correcting for verbal skills. Moreover, significant correlations between cognitive capacities (effortful control) and emotional abilities were evidenced. CONCLUSIONS Compared to their FT peers, 42 month-olds who were born very preterm are at higher risk of exhibiting specific emotional and effortful control difficulties. The results suggest that these difficulties are linked. Ongoing behavioral and emotional impairments starting at an early age in preterms highlight the need for early interventions based on a better understanding of the relationship between emotional and cognitive difficulties.

Abstract
Maternal smoking during pregnancy is one of the most modifiable causes of morbidity and mortality for both pregnant women and their fetuses. The long-term effects of prenatal exposure to smoke on child behavior and development have been the subject of more extensive research than have the short-term effects. Therefore, the aim of this work is to examine the effects of smoke exposure during pregnancy on neonatal behavior, including in our study a group of mothers exposed to secondhand smoke. The behavior of 282 healthy full-term newborns was assessed using the Neonatal Behavior Assessment Scale (NBAS) at 48-72 h of life. Sixty-two mothers smoked during pregnancy (no mother smoked more than 15 cig/day) and 17 were exposed to secondhand smoke. After adjusting for socio-demographic and obstetric factors, both newborns whose mothers smoked and those whose mothers were exposed to secondhand smoke showed significantly lower scores in the habituation cluster than non-smoking mothers. Exposure to secondhand smoke was also related to lower motor system cluster scores as well as some supplementary items and the newborns of smoking mothers showed significantly lower scores in the state regulation cluster and in some items of the state organization cluster than the newborns of non-smoking mothers. We conclude that active and passive smoking during pregnancy affects several aspects of neurobehavioral development, regardless of socio-demographic, obstetric and pediatric factors.

Abstract
AIMS This paper describes the emotional and behavioural adjustment of children born very preterm (VPT) at early school age. Of particular interest was the degree of agreement between parents and teachers, and the extent of situational (parent or teacher) and pervasive (parent and teacher reported) adjustment problems. METHODS A regionally representative cohort of 104 VPT (≤33 weeks gestation) and 108 full-term (FT) children born during 1998-2000 was studied prospectively to age six. At corrected age six, child emotional and behavioural adjustment was assessed using the parent and teacher rated strengths and difficulties questionnaires. RESULTS According to parents, 6-year-old VPT children had odds of emotional, inattention/hyperactivity and peer problems that were 2.7 to 3.8 times higher than their FT peers. Similar difficulties were identified by teachers, but odds were much lower and nonsignificant (1.1-1.8). Agreement between parents and teachers was lower in the VPT than the FT group (mean alternative chance-correlated coefficient , AC(1) = 0.63 vs. 0.80). Examination of the extent of pervasively identified adjustment problems showed that VPT children had higher rates of emotional (6% vs. 1%) and inattention/hyperactivity problems (12% vs. 6%) than FT children. CONCLUSIONS Early school age, VPT children are at increased risk of pervasive emotional problems and inattention/hyperactivity, although these risks are relatively modest. The use of multiple informants to assess VPT children's well-being is important to minimise the effects of report source bias and the over-identification of adjustment problems in children born VPT.

Abstract
AIM To evaluate the predictive capacity of neonatal behaviour on infant mental and psychomotor development at 4 and 12 months, and infant intelligence at 6 years. METHOD Eighty full-term newborns were followed from 3 days until 6 years. Neonatal behaviour was assessed by the Neonatal Behavior Assessment Scale (NBAS) at 3 days postpartum, infant mental and psychomotor development was assessed by the Bayley Scales for Infant Development at 4 and 12 months, and child intelligence was assessed by the Wechsler Preschool and Primary Scale of Intelligence at 6 years. RESULTS Neonatal general irritability was the predictor of mental development at 12 months. Self-regulation behaviours were predictors of psychomotor development at 4 and 12 months and verbal and total intelligence quotient at 6 years. Neonatal orientation was a predictor of performance Wechsler subtests related to visomotor abilities and attention. CONCLUSIONS Neonatal self-regulation behaviours were the best predictors of infant development and intelligence. We suggest that the NBAS could be a useful tool to observe behaviours related to later development in healthy infants.

Abstract
Animal and human studies have shown that prenatal and postnatal iron deficiency is a risk factor for behavioral, emotional and cognitive development. The aim of this study was to determine the associations between iron status of pregnant women and the behavior of their newborn, taking into account the timing in which the deficit occurs. This study was conducted in Spain (developed country) where: the general population is well-nourished; during pregnancy routine obstetrical checks are carried out; and pregnant women are systematically iron supplemented. A total of 216 healthy and well-nourished pregnant women and their term, normal weight newborn participated in this study. The neonatal behavior was assessed by the Neonatal Behavior Assessment Scale (NBAS). The results showed that in the first and second trimesters of pregnancy, iron deficiency was a weak and significant predictor of the NBAS autonomous nervous system cluster score, and in the third trimester, this condition predicted the NBAS motor and state organization clusters score and the NBAS robustness and endurance supplementary item. In conclusion, iron deficiency during pregnancy is related to the neonate's general autonomous response, motor performance and self regulation capabilities.

Abstract
Over the decades, the evolution of neonatology has been a continuum. After intense focus on cardiac and respiratory support, now more time, effort and research are concerned about brain development of the term and preterm infants. There is no single standardized neurodevelopmental assessment tool that can be advocated for infants in the neonatal intensive care unit. The tools that are currently available vary in their physiological bases, pre requisite training and expertise, time allotted to perform and score, and clinical utility and validity. In this communication, we describe the neurobehavioral and sensory capabilities of the neonate. We then compare the commonly used neurobehavioral examinations with an emphasis on premature infants. We envision this effort as an essential step before the development of a universal and comprehensive assessment tool.

Abstract
The aim of this work is to study whether maternal anxiety is related to different neonatal behaviour in boys and girls. In boys (n=128), maternal anxiety is related to lower state organization and to increased autonomic stability. Girls' (n=131) behaviour is not related to maternal anxiety.

Abstract
We investigated the relationship between prenatal maternal urinary concentrations of phthalate metabolites and neonatal behavior in their 295 children enrolled in a multiethnic birth cohort between 1998 and 2002 at the Mount Sinai School of Medicine in New York City. Trained examiners administered the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) to children within 5 days of delivery. We measured metabolites of 7 phthalate esters in maternal urine that was collected between 25 and 40 weeks' gestation. All but two phthalate metabolites were over 95% detectable. We summed metabolites on a molar basis into low and high molecular weight phthalates. We hypothesized the existence of sex-specific effects from phthalate exposure a priori given the hormonal activity of these chemicals. Overall we found few associations between individual phthalate metabolites or their molar sums and most of the BNBAS domains. However, we observed significant sex-phthalate metabolite interactions (p<0.10) for the Orientation and Motor domains and the overall Quality of Alertness score. Among girls, there was a significant linear decline in adjusted mean Orientation score with increasing urinary concentrations of high molecular weight phthalate metabolites (B=-0.37, p=0.02). Likewise, there was a strong linear decline in their adjusted mean Quality of Alertness score (B=-0.48, p<0.01). In addition, boys and girls demonstrated opposite patterns of association between low and high molecular weight phthalate metabolite concentrations and motor performance, with some indication of improved motor performance with increasing concentration of low molecular weight phthalate metabolites among boys. This is the first study to report an association between prenatal phthalate exposure and neurological effects in humans or animals, and as such requires replication.

Do the emotional states of pregnant women affect neonatal behaviour? Early Hum Dev 2008; 84:745-50.

Abstract
The emotional states of pregnant women affect the course of their pregnancies, their deliveries and the behaviour and development of their infants. The aim of this study is to analyse the influence of positive and negative maternal emotional states on neonatal behaviour at 2-3 days after birth. A sample of 163 healthy full-term newborns was evaluated using the Neonatal Behavioral Assessment Scale. Maternal anxiety, perceived stress, and emotional stability during pregnancy were evaluated in the immediate postpartum period with the State Trait Anxiety Inventory and the Perceived Stress Scale. Moderate levels of anxiety during pregnancy alter infant orientation and self-regulation. These aspects of infant behaviour could lead to later attachment, behavioural and developmental problems. Maternal emotional stability during pregnancy improves infant self-regulation and several aspects of infant behaviour that may predispose them to better interactions with their parents.

Abstract
Responsiveness in prematurely and term-born infants was studied cross-sectionally in relation to maternal confidence. Orientation and arousal were measured in 140 prematurely (mean BW 1,398 g, GA 30.1 weeks) and 75 term-born infants (mean BW 3,613 g, GA 39.3 weeks) with the Neonatal Behavioral Assessment Scales. Mothers filled out the Maternal Confidence Questionnaire and a modified version of the Parenting Stress Index. Prematurely born infants had a significantly lower level of arousal than term-born neonates. Responsiveness was not associated with maternal confidence. Lower confidence was associated with primiparity in both groups of mothers. Multiparous mothers of prematurely born infants had significantly lower levels of confidence than multiparous mothers of term-born infants. Confidence was significantly associated with stress for mothers of prematurely and term-born infants, and may be focused in follow-up after giving birth. Prematurely born infants should be examined more thoroughly in aspects of arousal at the time of discharge.

Abstract
AIM To examine the predictive capacity of the Neonatal Behavioral Assessment Scale (NBAS) on psychological problems at the age of 6 y. METHODS Eighty full-term infants of optimal health were evaluated at 3 d and 4 wk of age with the NBAS and at 6 y with the Child Behavior Checklist (CBCL) and the Inattention-Overactivity with Aggression Conners Teacher's Rating Scale (IOWA). RESULTS The NBAS clusters' predictive value was different at 3 d and at 4 wk. Orientation at 3 d and habituation at 4 wk were the best predictors of psychological problems. At 3 d, lower orientation scores and higher motor and habituation scores predicted higher scores in externalizing problems. Externalizing problems were least influenced by background variables. Only in girls were internalizing problems associated with lower orientation scores. At 4 wk, lower habituation cluster scores predicted higher scores in internalizing problems. CONCLUSION These findings suggest that the NBAS could be useful for identifying neonates at risk of later psychological problems.

Abstract
This study examined the etiology and course of anxiety symptoms from infancy through adolescence in a longitudinal high-risk community sample. One hundred fifty-five subjects were assessed using a variety of observational, projective, and objective measures. Results of path analyses revealed the following: (a) anxiety symptoms showed moderate stability during childhood and adolescence; (b) heightened neonatal biobehavioral reactivity and poor regulation predicted emotion regulation difficulties in preschool, which predicted anxiety symptoms in childhood; (c) developmental incompetence in childhood predicted anxiety symptoms in preadolescence, and anxiety symptoms in preadolescence predicted incompetence in adolescence; (d) insecure attachment relationships in infancy predicted negative peer relationship representations in preadolescence, and these representations predicted anxiety symptoms in adolescence; (e) compared to males, females showed similar rates of anxiety symptoms in childhood but greater and more stable rates in adolescence; however, males and females showed similar patterns of association between risk factors and anxiety symptoms across childhood and adolescence; and (f) the model tested was specific in predicting anxiety symptoms and not psychopathology in general. The results support a developmental model of the etiology and maintenance of anxiety symptoms in childhood and highlight factors to consider in efforts to prevent and treat childhood anxiety.

Abstract
The authors examined the relationship between newborn neurobehavioral profiles and the characteristics of early mother-infant interaction in Nagasaki, Japan. The authors administered the Brazelton Neonatal Behavioral Assessment Scale (NBAS; T. B. Brazelton & J. K. Nugent, 1995) in the newborn period and the Nursing Child Assessment Teaching Scale at 1 month (NCATS; G. Sumner & A. Spietz, 1994). They administered the Perceived Stress Scale (S. Cohen, T. Kamarck, & R. Mermelstein, 1983) as an index of maternal stress experienced over the past month. Lower irritability, higher stability in skin coloration, and lower tremulousness in the neonatal period were correlated with higher levels of maternal nurturing behaviors at 1 month. Birth weight and 2 NBAS range-of-state items (peak of excitement, irritability) predicted 31% of the variance in NCATS caregiver subscale score. The NBAS autonomic stability items (tremulousness, startles, lability of skin color) predicted 31% of the variance in the NCATS child subscale score. Perceived stress and maternal sociodemographic variables (education, income, age, parity) were not associated with child, caregiver, and total scores on the NCATS. The results suggested that lack of autonomic stability in Japanese neonates might serve as an early indicator of infant frailty, negative behavioral cues, and decreased maternal responsiveness.
