Developmental trajectories of late preterm infants and predictors of academic performance.

BACKGROUND: The trajectories of late preterm development from infancy to kindergarten reading and math, and predictors of academic resilience and risk are unknown. METHODS: Sample included 1200 late preterm infants (LPIs) from the Early Childhood Longitudinal Study, Birth Cohort. Objective measurements of development at 9 and 24 months (Bayley-SFR) and reading and math academic achievement at preschool and kindergarten were standardized; trajectories of late preterm development from 9 months to kindergarten reading and math were identified using latent class growth analysis. Multinomial logistic regression [aOR, 95% CI] identified predictors of academic resilience and risk. RESULTS: Four trajectory groups were observed for reading and three for math. More optimal trajectories (in reading and math) and academic resilience were associated with experiencing sensitive parenting and preschool attendance. Suboptimal (at-risk) trajectories (in reading or math) and an increased odds of academic risk were associated with

Ecological contexts associated with early childhood curiosity: Neighborhood safety, home and parenting quality, and socioeconomic status.

Introduction: Curiosity is an important social-emotional process underlying early learning. Our previous work found a positive association between higher curiosity and higher academic achievement at kindergarten, with a greater magnitude of benefit for children with socioeconomic disadvantage. Because characteristics of the early caregiving and physical environment impact the processes that underlie early learning, we sought to examine early environmental experiences associated with early childhood curiosity, in hopes of identifying modifiable contexts that may promote its expression. Methods: Using data from a nationally representative sample of 4,750 children from the United States, this study examined the association of multi-level ecological contexts (i.e., neighborhood safety, parenting quality, home environment, and center-based preschool enrollment) on early childhood curiosity at kindergarten, and tested for moderation by socioeconomic status. Results: In adjusted, stratified models, children from lower-resourced environments (characterized by the lowest-SES tertile) manifested higher curiosity if they experienced more positive parenting, higher quality home environments, and if they lived in "very safe" neighborhoods. Discussion: We discuss the ecological contexts (i.e., parenting, home, and neighborhood environments) that are promotive of early childhood curiosity, with an emphasis on the role of the neighborhood safety and the "neighborhood built environment" as important modifiable contexts to foster early childhood curiosity in lower-resourced families.

Infant-Directed Speech From a Multidimensional Perspective: The Interplay of Infant Birth Status, Maternal Parenting Stress, and Dyadic Co-regulation on Infant-Directed Speech Linguistic and Pragmatic Features.

Infant-directed speech (IDS), the particular form of spontaneous language observed in interactions between parents and their infants, is a crucial aspect of the mother-infant interaction and an index of the attunement of maternal linguistic input to her infant communicative abilities and needs during dyadic interactions. The present study aimed to explore linguistic and pragmatic features of IDS during mother-infant interactions at 3-month of infant age. The effects of infant (birth status: preterm vs. full-term birth), maternal (perceived parenting stress) and dyadic (dyadic co-regulation) factors on IDS were explored. Results evidenced few differences between the groups on IDS linguistic characteristics. Moreover, observing the interaction of birth status and dyadic co-regulation, full-term mothers varied their IDS pragmatic features according to the quality of co-regulation while preterm mothers did not. Parenting stress was associated to specific linguistic IDS features independently from the birth status. Findings are discussed underling implications for the study of preterm dyads interactions and the importance to consider the interplay of several factors in affecting the quality of IDS.

In-the-moment ratings on the Early Relational Health Screen: A pilot study of application in home visiting and primary care.

Early infant-parent interaction sets a critical foundation for young children's well-being, and evidence regarding the protective role of secure early relationships has led to increased interest in effective screening and promotion of early relational health in pediatric primary care and home visiting settings. We report findings from two pilot studies conducted in the United States that describe the reliability and validity of a relational health screening tool, the Early Relational Health Screen (ERHS), implemented in two different contexts: an innovative model of relational health promotion in pediatric primary care (Study 1) and an Infant Mental Health Home Visiting (IMH-HV) model (Study 2). Across both studies, a trained clinician rated the ERHS following real-time observation of interaction (i.e., "in-the-moment" ratings). Reliability was assessed by comparing "in-the-moment" ERHS ratings to subsequent coding of the same interaction from video by an independent evaluator. In addition, Study 2 data permitted evaluation of the validity of "in-the-moment" ERHS ratings. Results from both studies indicated reliability of "in-the-moment" ERHS ratings. In addition, Study 2 clinician "in-the-moment" ratings were associated with maternal depression and ratings of child-parent interaction derived from a separate observational task coded by independent evaluators using a different well-validated research-based measure. Discussion highlights the potential of the ERHS as a screening, promotion, and prevention tool that may be feasibly administered by providers across pediatric primary care and home visiting settings.

La temprana interacción infante-progenitor establece una fundación esencial para el bienestar de los niños pequeños, y la evidencia sobre el papel de protección de tempranas relaciones receptivas ha aumentado el interés en la efectiva detección y promoción de la salud de la relación en el cuidado pediátrico primario y los escenarios de visitas a casa. Reportamos los resultados de dos estudios experimentales que describen la confiabilidad y validez de la Temprana Detección de la Salud de la Relación (ERHS) implementada en dos contextos: un modelo innovador de promoción de la salud de la relación en el cuidado primario (Estudio 1) y un modelo de salud mental infantil de visitas a casa (Estudio 2). A lo largo de ambos, un profesional clínico entrenado evaluó ERHS siguiendo una observación de interacción en tiempo real (v.g. puntajes asignados "en el momento"). Se evaluó la confiabilidad por medio de una comparación entre los puntajes del profesional clínico y los subsecuentes puntajes de la misma interacción en video por un evaluador independiente. Adicionalmente, los datos del Estudio 2 permitieron la evaluación de la validez de los puntajes de ERHS. Los resultados de ambos estudios indicaron la confiabilidad de los puntajes ERHS "en el momento." Es más, los puntajes del profesional clínico del Estudio 2 se asociaron con la depresión materna y los puntajes de la interacción niño-progenitor derivados de una tarea separada usando una medida bien validada basada en la investigación. Las discusiones subrayan el potencial de ERHS como una herramienta de detección, promoción y prevención que puede ser administrada factiblemente por los proveedores tanto en el cuidado primario como en los casos de visitas a casa.

L'interaction précoce nourrisson-parent jette les bases essentielles du bien-être du jeune enfant et l'évidence concernant le rôle protecteur des relations précoces sécures a mené à un intérêt plus grand pour le dépistage efficace et la promotion de la santé relationnelle précoce dans les soins de santé primaire en pédiatrie ainsi que les contextes de visites à domicile. Nous rapportons ici les résultats de deux études pilotes faites aux Etats-Unis d'Amérique, qui décrivent la fiabilité et la validité d'un outil de dépistage de la santé relationnelle, le Dépistage Précoce de Santé Relationnelle (en anglais Early Relational Health Screen dont nous gardons l'abréviation ici, ERHS), mis en place dans deux contextes différents: un modèle innovateur de promotion de la santé relationnelle précoce en soin pédiatrique primaire (Etude 1) et un modèle de visite à domicile pour la santé mentale du nourrisson (Etude 2). Au travers de ces deux études un clinicien entraîné a évalué l'ERHS après une observation en temps réel de l'interaction (c'est-à-dire, des scores "sur le moment"). La fiabilité a été évaluée en comparant l'ERHS "sur le moment" au codage ultérieur de la même interaction à partir d'une vidéo, par un évaluateur indépendant. De plus les données de l'Etude 2 ont permis l'évaluation de la validité des scores ERHS "sur le moment." Les résultats des deux études ont indiqué la fiabilité des scores ERHS "sur le moment." De plus les scores "sur le moment" du clinicien de l'Etude 2 étaient liés à la dépression maternelle et aux scores d'interaction enfant-parent dérivés d'une tâche observationnelle séparée codée par des évaluateurs indépendants en utilisant une mesure basée sur les recherches différente et communément validée. La discussion met en lumière le potentiel de l'ERHS en tant qu'outil de dépistage, de promotion et de prévention qui peut être réalistement utilisé par les professionnels au sein des soins primaires pédiatriques et des contextes de visites à domicile.

Multimodal assessments of preterm temperament across the first year of life: Continuity, stability, and moderation by country of origin and infant age.

There is limited research regarding the continuity, stability, and role of country of origin in preterm infant temperament across the first year of life. This prospective longitudinal study examined patterns of mean-level continuity and individual-differences stability of select scales of temperament at 6 and 12 months in preterm infants from three countries, Chile (n = 47), United Kingdom (n = 44), and United States (n = 50). Temperament was assessed with the Infant Behavior Questionnaire and observed using the Bayley Behavior Rating Scale. Continuity and stability across infant age, country effects, and interactions of country and age on preterm infant temperament were examined. Chilean mothers rated infants higher in soothability, duration of orienting, and orientation/engagement compared with mothers from the United Kingdom and/or United States. Continuity of temperament from 6 to 12 months varied by country: Chilean mothers reported increasing smiling and laughter and activity level from 6 to 12 months, and mothers from the United Kingdom reported decreasing smiling and laughter and increasing fear from 6 to 12 months. Infant temperament was stable in all three countries. Correlations evidenced low concordance between maternal reports and examiner observations of infant temperament at 12 months. However, among Chilean infants, higher maternal reported activity level was associated with higher examiner observed orientation/engagement score.

Hay una limitada investigación acerca de la continuidad, la estabilidad y el papel del país de origen en el temperamento de infantes nacidos prematuramente a lo largo del primer año de vida. Este potencial estudio longitudinal examinó patrones de continuidad en el promedio de nivel y las diferencias individuales en cuanto a la estabilidad de selectas escalas de temperamento a los 6 y 12 meses en infantes prematuros de tres países, Chile (n = 47), Reino Unido (n = 44) y Estados Unidos (n = 50). El temperamento se evaluó con el Cuestionario de Comportamiento del Infante y el mismo se observó usando la Escala de Puntuación del Comportamiento de Bayley. Se examinaron la continuidad y la estabilidad a lo largo de la edad del infante, los efectos del país, así como las interacciones entre país y edad en el temperamento de los infantes prematuros. Las madres chilenas evaluaron a sus infantes con más altos puntajes en cuanto a posibilidad de tranquilizarlos, duración de orientarlos y la orientación/participación en comparación con madres del Reino Unidos y/o de Estados Unidos. La continuidad de temperamento de los 6 a 12 meses varió según el país: las madres chilenas reportaron aumento en la sonrisa y la risa, y el nivel de actividad de los 6 a 12 meses, y las madres del Reino Unido reportaron una disminución en la sonrisa y la risa, y un aumento en el temor de los 6 a 12 meses. El temperamento del infante fue estable en los tres países. Las correlaciones son evidencia de la concordancia entre los reportes maternos y las observaciones del examinador del temperamento del infante a los 12 meses. Sin embrago, entre los infantes chilenos, el más alto nivel de actividad reportado por las madres se asoció con un más alto puntaje del examinador en cuanto a la observada orientación/participación.

Nous n'avons que des recherches limitées sur la continuité, la stabilité et le rôle du pays d'origine dans le tempérament du bébé prématuré au fil de la première année de la vie. Cette étude longitudinale prospective a examiné les modèles de continuité au niveau moyen et la stabilité des différences individuelles de certaines échelles de tempérament à 6 et à 12 mois chez les enfants prématurés de trois pays, le Chili (n = 47), le Royaume Uni (n = 44) et les Etats-Unis d'Amérique (n = 50). Le tempérament a été évalué au moyen du Questionnaire du Comportement du Nourrisson et observé en utilisant l'Echelle de Bailey d'Evaluation du Comportement du Nourrisson. La continuité et la stabilité au travers de l'âge du nourrisson, les effets du pays et les interactions du pays et de l'âge sur le tempérament du bébé prématuré ont été examinés. Les mères chiliennes ont évalué leurs bébés plus haut pour ce qui concernait la capacité à être calmé, la durée de l'orientation et l'orientation/l'engagement par comparaison aux mères du Royaume Uni et/ou des Etats-Unis. La continuité du tempérament de 6 à 12 mois a varié par pays: les mères chiliennes ont fait état de plus de sourires et de rires et d'un niveau d'activité plus élevé de 6 à 12 mois et les mères du Royaume Uni ont fait état d'une décroissance des sourires et des rires et d'une plus grande peur de 6 à 12 mois. Le tempérament du nourrisson était stable dans les trois pays. Les corrélations ont montré une concordance faible entre les rapports maternels et les observations de l'examinateur du tempérament du nourrisson à 12 mois. Cependant, chez les enfants chiliens, un niveau d'activité plus élevé rapporté par la mère était lié à un score d'orientation/d'engagement observé plus élevé de la part de l'examinateur.

Daily television exposure, parent conversation during shared television viewing and socioeconomic status: Associations with curiosity at kindergarten.

OBJECTIVE: To examine the main and interactive effects of the amount of daily television exposure and frequency of parent conversation during shared television viewing on parent ratings of curiosity at kindergarten, and to test for moderation by socioeconomic status (SES). STUDY DESIGN: Sample included 5100 children from the Early Childhood Longitudinal Study, Birth Cohort. Hours of daily television exposure and frequency of parent screen-time conversation were assessed from a parent interview at preschool, and the outcome of early childhood curiosity was derived from a child behavior questionnaire at kindergarten. Multivariate linear regression examined the main and interactive effects of television exposure and parent screen-time conversation on kindergarten curiosity and tested for moderation by SES. RESULTS: In adjusted models, greater number of hours of daily television viewing at preschool was associated with lower curiosity at kindergarten (B = -0.14, p = .008). More frequent parent conversation during shared screen-time was associated with higher parent-reported curiosity at kindergarten with evidence of moderation by SES. The magnitude of association between frequency of parent conversation during television viewing and curiosity was greater for children from low SES environments, compared to children from high SES environments: (SES ≤ median): B = 0.29, p < .001; (SES > median): B = 0.11, p < .001. CONCLUSIONS: Higher curiosity at kindergarten was associated with greater frequency of parent conversation during shared television viewing, with a greater magnitude of association in low-SES families. While the study could not include measures of television program content, digital media use and non-screen time conversation, our results suggest the importance of parent conversation to promote early childhood curiosity, especially for children with socioeconomic disadvantage.

Interactive Effects of Infant Gestational Age and Infant Fussiness on the Risk of Maternal Depressive Symptoms in a Nationally Representative Sample.

OBJECTIVE: To examine the interactive effects of gestational age and infant fussiness on the risk of maternal depressive symptoms in a nationally representative sample. METHODS: Our sample included 8200 children from the Early Childhood Longitudinal Study, Birth Cohort. Gestational age categories were very preterm (VPT, 24-31 weeks), moderate/late preterm (MLPT, 32-36 weeks) and full term (FT, 37-41 weeks). Maternal depressive symptoms (categorized as nondepressed/mild/moderate-severe), from the modified Center for Epidemiological Studies Depression Questionnaire, and infant fussiness (categorized as fussy/not fussy) were assessed at 9 months from parent-report questionnaires. We examined the interactive effects of infant fussiness and gestational age categories and estimated adjusted odds ratios (aOR) and 95% confidence intervals (CI) of maternal depressive symptoms using multinomial logistic regression. RESULTS: Infant fussiness interacted with gestational age categories in predicting maternal depressive symptoms (P = .04), with severity varying by gestational age and infant fussiness. Compared with mothers of VPT infants without fussiness, mothers of VPT infants with fussiness had greater odds of mild depressive symptoms (aOR, 2.32; 95% CI, 1.19-4.53). Similarly, compared with mothers of MLPT and FT infants without fussiness, mothers of fussy MLPT and FT infants had greater odds of moderate-severe symptoms (aOR, 2.30; 95% CI, 1.40-3.80, and aOR, 1.74; 95% CI, 1.40-2.16, respectively). CONCLUSIONS: Mothers of MLPT and FT infants with fussiness had increased odds of moderate-severe depressive symptoms, and mothers of VPT infants with fussiness had increased risk of mild symptoms. Early screening for infant fussiness in preterm and FT may help identify mothers with depressive symptoms in need of support.

Lower Body Mass Index Z-Score Trajectory During Early Childhood After the Birth of a Younger Sibling.

OBJECTIVE: The objectives of this study were to examine differences in body mass index z-score (BMIZ) trajectory during early childhood among children with a younger sibling compared with those without and to test potential mediators. METHODS: This longitudinal cohort study included 6050 participants of the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B). Focal children's weight, height, sibship status, screen time, active play time, family dinner frequency, and diet quality were assessed at 9 months, 24 months, preschool, and kindergarten when available. A piecewise linear regression model was used to examine the association between sibling birth and focal child's subsequent BMIZ trajectory to kindergarten. Mediation by screen time, active play time, family dinner frequency, and diet quality was tested. RESULTS: BMIZ trajectory was lower among children who had a new sibling join the family before kindergarten compared to children who did not have a new sibling join the family by kindergarten. The association was strongest when new sibship occurred when the focal child was 48 to 66 months (b = -0.026, P = .044). The association was not mediated by screen time, active play time, family dinner frequency, or diet quality. CONCLUSION: Among a nationally representative cohort of US children, new sibship before kindergarten was associated with a lower BMIZ trajectory. Several common obesogenic risk factors did not explain the association.

The Influence of Early Temperament on Language Development: The Moderating Role of Maternal Input.

Temperament is an individual aspect that strictly affects infants and children engagement with the environment and it is supposed to play a role in the acquiring of new competences. Several studies focused on the possible influence of temperament in the process of language acquisition in early childhood reporting not consistent findings. Since maternal input is a variable that has been widely associated with infant language development this longitudinal study aimed to explore the role of the quality of maternal input in the temperament-language association. We hypothesized that the longitudinal association between early infant temperament and language production is moderated by the quality of maternal input during the first year of life. Infant temperament at 3 months and maternal linguistic input (lexical diversity and syntactic complexity) during spontaneous mother-infant interactions at 6, 9, and 12 months were assessed. Language competences were evaluated at the end of the second year: language production at 18 months with the CDI and child syntactic complexity at 24 months during spontaneous speech. Results showed significant moderating effects of syntactic complexity and lexical variability of maternal input at 6 and 9 months on the association of duration of orienting abilities and later language production. Infants with greater attentional abilities and with mothers who spoke to them with a more complex and variable input showed the better language outcomes. The association between infant distress to limitations and child language was not moderated by maternal input. No effects were found when considering the temperamental scale smile and laugher. Attentional control temperamental characteristics could help the infant to be more focus on maternal input throughout the first year of life and could consequently facilitate language development. Our findings underlined the necessity to explore infant development considering the interaction between individual and contextual factors.

Early childhood curiosity and kindergarten reading and math academic achievement.

BACKGROUND: Although children's curiosity is thought to be important for early learning, the association of curiosity with early academic achievement has not been tested. We hypothesized that greater curiosity would be associated with greater kindergarten academic achievement in reading and math. METHODS: Sample included 6200 children in the Early Childhood Longitudinal Study, Birth Cohort. Measures at kindergarten included direct assessments of reading and math, and a parent-report behavioral questionnaire from which we derived measures of curiosity and effortful control. Multivariate linear regression examined associations of curiosity with kindergarten reading and math academic achievement, adjusting for effortful control and confounders. We also tested for moderation by effortful control, sex, and socioeconomic status (SES). RESULTS: In adjusted models, greater curiosity was associated with greater kindergarten reading and math academic achievement: breading = 0.11, p < 0.001; bmath = 0.12, p < 0.001. This association was not moderated by effortful control or sex, but was moderated by SES (preading = 0.01; pmath = 0.005). The association of curiosity with academic achievement was greater for children with low SES (breading = 0.18, p < 0.001; bmath = 0.20, p < 0.001), versus high SES (breading = 0.08, p = 0.004; bmath = 0.07, p < 0.001). CONCLUSIONS: Curiosity may be an important, yet under-recognized contributor to academic achievement. Fostering curiosity may optimize academic achievement at kindergarten, especially for children with low SES.

Updated Clinical Guidelines for Diagnosing Fetal Alcohol Spectrum Disorders.

The adverse effects of prenatal alcohol exposure constitute a continuum of disabilities (fetal alcohol spectrum disorders [FASD]). In 1996, the Institute of Medicine established diagnostic categories delineating the spectrum but not specifying clinical criteria by which diagnoses could be assigned. In 2005, the authors published practical guidelines operationalizing the Institute of Medicine categories, allowing for standardization of FASD diagnoses in clinical settings. The purpose of the current report is to present updated diagnostic guidelines based on a thorough review of the literature and the authors' combined expertise based on the evaluation of >10 000 children for potential FASD in clinical settings and in epidemiologic studies in conjunction with National Institute on Alcohol Abuse and Alcoholism-funded studies, the Collaborative Initiative on Fetal Alcohol Spectrum Disorders, and the Collaboration on FASD Prevalence. The guidelines were formulated through conference calls and meetings held at National Institute on Alcohol Abuse and Alcoholism offices in Rockville, MD. Specific areas addressed include the following: precise definition of documented prenatal alcohol exposure; neurobehavioral criteria for diagnosis of fetal alcohol syndrome, partial fetal alcohol syndrome, and alcohol-related neurodevelopmental disorder; revised diagnostic criteria for alcohol-related birth defects; an updated comprehensive research dysmorphology scoring system; and a new lip/philtrum guide for the white population, incorporating a 45-degree view. The guidelines reflect consensus among a large and experienced cadre of FASD investigators in the fields of dysmorphology, epidemiology, neurology, psychology, developmental/behavioral pediatrics, and educational diagnostics. Their improved clarity and specificity will guide clinicians in accurate diagnosis of infants and children prenatally exposed to alcohol.

Gestational Age and Kindergarten School Readiness in a National Sample of Preterm Infants.

OBJECTIVE: To examine the association of gestational age with school readiness in kindergarten reading and math skills. We hypothesized that compared with infants born at 39-41 weeks, infants born at lower gestational ages would have poorer school readiness. STUDY DESIGN: The study sample comprised 5250 children from the Early Childhood Longitudinal Study, Birth Cohort, assessed with specialized reading and math assessments at kindergarten. Poor school readiness was characterized by reading and math theta scores ≥1.5 SD below the sample mean. The aOR and 95% CI of poor school readiness were estimated using multivariate logistic regression, examining gestational age continuously and categorically (very preterm [VPT], moderate/late preterm [M/LPT], early term [ET], and term). Pairwise comparisons were performed to test for differences by gestational age category. RESULTS: There was an association between gestational age and poor school readiness for reading and math, with the suggestion of a threshold effect in children born at ≥32 weeks gestation. In adjusted models, in VPT infants, the aORs of poor school readiness in reading and math were 2.58 (95% CI, 1.29-5.15) and 3.38 (95% CI, 1.66-6.91), respectively. For infants born M/LPT and ET, the odds of poor school readiness in reading did not differ from those of children born full-term, however. CONCLUSIONS: Compared with term infants, the highest odds of poor school readiness in reading and math were seen in VPT infants, with lower odds of poor school readiness in children born at ≥32 weeks gestation. Ongoing developmental surveillance before kindergarten is indicated for VPT infants.

Sleep and Attachment in Preterm Infants.

Infants born preterm are at elevated risk for social emotional difficulties. However, factors contributing to this risk are largely understudied. Within the present study, we explored infant sleep as a biosocial factor that may play a role in infant social emotional development. Within a prospective longitudinal design, we examined parent-reported sleep patterns and observed parenting quality as predictors of infant-mother attachment in 171 infants born preterm. Using structural equation modeling, we examined main effect and moderator models linking infant sleep patterns and parenting with attachment security. Sleep patterns characterized by more daytime sleep and positive/responsive parenting predicted infant attachment security. Parent-reported nighttime sleep patterns were unrelated to attachment in this sample of infants born preterm. These results indicate that daytime sleep and parenting quality may be important for emerging attachment relationships in infants born preterm.

The paradox of prematurity: the behavioral vulnerability of late preterm infants and the cognitive susceptibility of very preterm infants at 36 months post-term.

We explored associations among preterm status (very preterm infant (VPI: <30 weeks), moderate preterm (MPI: 30-33(6/7) weeks), late preterm (LPI: 34-36(6/7) weeks), parenting, and 3-year cognitive and behavioral outcomes. We hypothesized that LPIs would demonstrate better health and neurobehavioral outcomes compared with more premature infants, and that preterm status would moderate the association between parenting quality and 3-year outcomes. Sample included 123 preterm infants (gestation <37 weeks) and their mothers from a larger study of high-risk infants with measures of neonatal and socioeconomic risks at hospital discharge; maternal vocabulary at 9-months, child IQ and behavior at 36 months, and maternal depressive symptoms and parenting at all timepoints. Group differences were explored using MANOVAs while predictors of child outcomes were explored using hierarchical regression analyses. MANOVAs indicated that LPIs had more optimal neonatal health during the hospital stay, yet more externalizing (p=.043), aggressive (p=.006) and oppositional behaviors (p=.008) at 3 years compared with VPIs. There were no IQ differences between VPIs, MPIs and LPIs. However, preterm infants who experienced less negative parenting had higher IQs at 36 months (ß=-3.245, p=.017), with the greatest effects seen in VPIs (ß=0.406, p=.01) compared with LPIs (ß=0.148, p=.381). LPIs manifested similar IQ, but more externalizing, oppositional and aggressive behavior symptoms compared to VPIs. VPIs appeared to be differentially susceptible to parenting effects, with VPIs demonstrating the highest cognitive scores in the context of more positive parenting.

Long-term outcomes of group B streptococcal meningitis.

OBJECTIVE: Group B Streptococcus (GBS) is the leading cause of meningitis in young infants. We evaluated long-term outcomes among GBS meningitis survivors. We hypothesized that despite reduced mortality, GBS meningitis would remain a significant cause of morbidity among GBS survivors. METHODS: Ninety term and near-term infants diagnosed with GBS meningitis from 1998 through 2006 were identified from 2 children's hospitals. Five died acutely, and 5 died at 6 months to 3 years of age. Forty-three survivors (54%; mean age 6.8, range 3-12 years) were consented for evaluation and underwent physical and neurologic examinations, hearing and vision screening, and standardized developmental assessments. Associations among presenting features, laboratory parameters, neurologic status at hospital discharge, and later developmental outcomes were explored by using descriptive statistics and logistic regression. RESULTS: Twenty-four of 43 (56%) children evaluated demonstrated age-appropriate development, 11 (25%) had mild-to-moderate impairment, and 8 (19%) had severe impairment. Admission features associated with death after hospital discharge or severe impairment included lethargy (P = .003), respiratory distress (P = .022), coma or semicoma (P = .022), seizures (P = .015), bulging fontanel (P = .034), leukopenia (P = .026), acidosis (P = .024), cerebrospinal fluid protein >300 mg/dL (P = .006), cerebrospinal fluid glucose <20 mg/dL (P = .026), and need for ventilator (P = .002) or pressor support (P < .001). Features at discharge associated with late death or severe impairment included failed hearing screen (P = .004), abnormal neurologic examination (P < .001), and abnormal end of therapy brain imaging (P = .038). CONCLUSIONS: Survivors of GBS meningitis continue to have substantial long-term morbidity, highlighting the need for ongoing developmental follow-up and prevention strategies such as maternal immunization.

Preterm infants who are prone to distress: differential effects of parenting on 36-month behavioral and cognitive outcomes.

BACKGROUND: The differential susceptibility (DS) model suggests that temperamentally prone-to-distress infants may exhibit adverse outcomes in negative environments but optimal outcomes in positive environments. This study explored temperament, parenting, and 36-month cognition and behavior in preterm infants using the DS model. We hypothesized that temperamentally prone to distress preterm infants would exhibit more optimal cognition and fewer behavior problems when early parenting was positive; and less optimal cognition and more behavior problems when early parenting was less positive. METHODS: Participants included 109 preterm infants (gestation <37 weeks) and their mothers. We assessed neonatal risk and basal vagal tone in the neonatal intensive care unit; infant temperament and parenting interactions at 9 months post-term; and child behavior and cognitive skills at 36 months post-term. Hierarchical regression analyses tested study hypotheses. RESULTS: Temperamentally prone-to-distress infants exhibited more externalizing problems if they experienced more critical parenting at 9 months (ß = -.20, p < 0.05) but fewer externalizing problems with more positive parenting. Similarly, variations in maternal positive affect (ß = .25, p < .01) and intrusive behaviors (ß = .23, p < .05) at 9 months predicted 36-month cognition at high but not at low levels of infant temperamental distress. Higher basal vagal tone predicted fewer externalizing problems (ß = -.19, p < .05). CONCLUSIONS: Early parenting behaviors relate to later behavior and development in preterm infants who are temperamentally prone to distress, and neonatal basal vagal tone predicts subsequent externalizing behaviors. These findings suggest that both biological reactivity and quality of caregiving are important predictors for later outcomes in preterm infants and may be considered as foci for developmental surveillance and interventions.

Optimizing the early parent-child relationship: windows of opportunity for parents and pediatricians.

This article explores child and parent risk factors that can affect the early parent-child relationship and highlights how a relational approach can be used in pediatric primary care to optimize early social-emotional development in the context of family-centered care. Risk factors, such as prematurity, parental mental illness, and a history of adverse care-giving experiences, can affect the parent-child relationship and influence later infant social-emotional development. The pediatrician, because of the ongoing relationship with the family, is in an optimal position to identify concerns, initiate interventions, and provide support and services to support the development of the early parent-child relationship.

Maternal resolution of grief after preterm birth: implications for infant attachment security.

OBJECTIVE: This study explored the association between mothers' unresolved grief regarding their infant's preterm birth and infant-mother attachment security. We hypothesized that mothers with unresolved grief would be more likely to have insecurely attached infants at 16 months and that this association would be partially mediated by maternal interaction quality. METHODS: This longitudinal study focused on 74 preterm infants (age of <36 weeks) and their mothers who were part of a larger study of high-risk infants. The present analysis included assessment of neonatal and socioeconomic risks at NICU discharge; maternal depression, Reaction to Preterm Birth Interview findings, and quality of parenting at a postterm age of 9 months; and infant-mother attachment at postterm age of 16 months. Associations among findings of grief resolution with the Reaction to Preterm Birth Interview, quality of parenting interactions, and attachment security were explored by using relative risk ratios and logistic and multivariate regression models. RESULTS: The relative risk of developing insecure attachment when mothers had unresolved grief was 1.59 (95% confidence interval: 1.03-2.44). Controlling for covariates (adjusted odds ratio: 2.94), maternal feelings of resolved grief regarding the preterm birth experience were associated with secure infant-mother attachment at 16 months. Maternal grief resolution and interaction quality were independent predictors of attachment security. CONCLUSION: Maternal grief resolution regarding the experience of preterm birth and the quality of maternal interactions have important implications for emerging attachment security for infants born prematurely.

The development of effortful control in children born preterm.

This prospective longitudinal study examined emerging effortful control skills at 24- and 36-months postterm in 172 children born preterm (<36 weeks gestation). Infant (neonatal health risks), family (sociodemographic risks), and maternal risk factors (depressive symptoms, anger expressions during play interactions) were assessed at six time points across 3 years. In addition, children's emerging effortful control skills, cognitive development, and mother-reported behavior and attention problems were assessed at 24 and 36 months. Analyses documented links between effortful control skills, cognitive skills, and concurrent attention problems in children born preterm. The study also found that preterm children's effortful control skills improved over time. In addition, neonatal health risks, family sociodemographic risks, and angry parenting interactions were associated with less optimal effortful control skills.

Is attachment transmitted across generations? The plot thickens.

Studies have demonstrated a strong relation between adult attachment security, using the Adult Attachment Interview (AAI), and infant security, using the Strange Situation Procedure (SSP). This suggests that a mother's representations of attachment may influence the development of her infant's attachment to her. This study both confirms and modifies that finding in a cohort of 47 first-time mothers and their infants. The AAIs were administered during the third trimester of pregnancy and the SSPs were performed when the infant was 14 months of age. The AAIs were classified using Crittenden's Dynamic-Maturational Model (DMM) and the SSPs using both the DMM and also Main and Solomon's ABC+D methods. There was a significant match of patterns for secure mothers and babies, but a tendency for inversion of insecure patterns of attachment, that is Type A mothers often had infants with a Type C pattern and vice versa. No significant relation was seen between the DMM adult and ABC+D infant patterns of attachment. A significant, but modest, association was found between the DMM and ABC+D infant SSP classifications. These findings may help guide treatment of insecure mother-infant dyads by individualizing interventions to include a focus on maternal representations of the infant and maternal responses to infant behavior.
