Verbal memory deficits in children with less than 750 g birth weight.

Numerous studies have documented memory deficits in very low birthweight (VLBW, < 1500 g) children, yet we know little about the nature of these memory problems. To clarify memory sequelae and examine memory deficits in relation to the degree of low birth weight, we administered the California Verbal Learning Test–Children’s Version (CVLT-C) to a regional sample of 57 < 750 g birthweight children and to groups of 53 750–1499 g birthweight children and 49 term-born controls. Group comparisons revealed significant differences between the < 750 g birthweight group and term-born children on measures of list learning, delayed recall, and inaccurate recall. In addition, the percentage improvement in correct recognitions relative to long-term delayed recall was greater in the < 750 g group than in the term-born controls. Similar differences were observed between VLBW children with and without abnormal neonatal cerebral ultrasounds (high- and low-risk groups). Differences in learning rate between the VLBW and term-born groups, and between high- and low-risk VLBW children, were evident even when vocabulary skill was covaried or when children with neurosensory deficits or IQ < 80 were excluded from analysis. The findings document deficits in verbal memory in the subset of VLBW children at greatest biological risk, and suggest that acquisition processes are selectively impaired.

The impact of extremely low birth weight on the families of school-aged children

OBJECTIVE. The purpose of this study was to document the impact and burden of extremely low birth weight (<1000 g) and associated problems on the families of school-aged children in a controlled study. The study was also designed to document the salient predictors of individual differences of family impact within the extremely low birth weight group. METHODS. A prospective study was completed at 8 years of a cohort of 219 children with extremely low birth weight born 1992–1995 and 176 children with normal birth weight. Measures included the following predictor variables: socioeconomic status and parent risk, birth risk, neonatal risk, neurodevelopmental outcome, impairment in adaptive abilities, and functional impact of chronic conditions. The primary outcome measure was the Impact on Family scale. A measure of family stressors and resources (the Life Stressors and Social Resources Inventory) was also obtained. RESULTS. The primary finding was that the total family impact was greater in the extremely low birth weight group compared with controls. Moreover, the negative impact on family in specific domains was greater in the extremely low birth weight group in financial impact, caretaker burden, and familial burden. These differences were not attributable to general family stressors, socioeconomic status, child, gender, or race. Higher parent/socioeconomic risk, neurodevelopmental outcomes, and the functional impact of chronic conditions predicted greater family impact within the extremely low birth weight group, whereas birth and neonatal risk scores did not. CONCLUSIONS. Extremely low birth weight was associated with a negative impact on families. Socioeconomic parental risk, but most especially child-related factors such as neurodevelopmental and the functional impact of chronic conditions, predicted the negative family impact within the extremely low birth weight group. Findings underscore the need to develop and test interventions to provide support for families of extremely low birth weight infants to ameliorate the burden of extremely low birth weight and associated risk factors on families.

Predictors of internalizing symptoms among very low birth weight young women

ABSTRACT. As part of a longitudinal study of the outcomes of very low birth weight children (<1.5 kg), we sought to examine the perinatal, childhood, and young adult predictors of internalizing symptoms among very low birth weight young women and their normal birth weight controls. The cohort included 125 very low birth weight and 124 normal birth weight 20-year-old subjects. Perinatal, childhood, and young adult predictors were examined via stepwise multivariate analyses. Results revealed very low birth weight to be a significant predictor of parent-reported internalizing symptoms of their daughters but only among white subjects who had mothers with high levels of psychological distress. Additional significant predictors of 20-year internalizing symptoms included child I.Q. and internalizing symptoms at age 8 years and family expressiveness. When the results were analyzed according to the young adult self-report, additional predictors of internalizing symptoms included a history of asthma and exposure to violence. Perinatal risk factors were not found to be predictive of internalizing symptoms at age 20 years. Future studies should prospectively examine social and environmental factors associated with the neonatal intensive care experience that might explain the effect of very low birth weight on later psychopathology.

Effects of Adenotonsillectomy on Parent-Reported Behavior in Children With Obstructive Sleep Apnea

Objectives The childhood obstructive sleep apnea syndrome (OSAS) is associated with behavioral abnormalities. Studies on the effects of OSAS treatment on behavior are conflicting, with few studies using a randomized design. Further, studies may be confounded by the inclusion of behavioral outcome measures directly related to sleep. The objective of this study was to determine the effect of adenotonsillectomy on behavior in children with OSAS. We hypothesized that surgery would improve behavioral ratings, even when sleep symptom items were excluded from the analysis. Methods This was a secondary analysis of Child Behavior Checklist (CBCL) data, with and without exclusion of sleep-specific items, from the Childhood Adenotonsillectomy Trial (CHAT). CBCL was completed by caregivers of 380 children (7.0+1.4 [range 5-9] years) with OSAS randomized to early adenotonsillectomy (eAT) versus 7 months of watchful waiting with supportive care (WWSC). Results There was a high prevalence of behavioral problems at baseline; 16.6% of children had a Total Problems score in the clinically abnormal range. At follow-up, there were significant improvements in Total Problems (p < .001), Internalizing Behaviors (p = .04), Somatic Complaints (p = .01), and Thought Problems (p = .01) in eAT vs. WWSC participants. When specific sleep-related question items were removed from the analysis, eAT showed an overall improvement in Total (p = .02) and Other (p = .01) problems. Black children had less improvement in behavior following eAT than white children, but this difference attenuated when sleep-related items were excluded. Conclusions This large, randomized trial showed that adenotonsillectomy for OSAS improved parent-rated behavioral problems, even when sleep-specific behavioral issues were excluded from the analysis.

Reading related white matter structures in adolescents are influenced more by dysregulation of emotion than behavior

Mood disorders and behavioral are broad psychiatric diagnostic categories that have different symptoms and neurobiological mechanisms, but share some neurocognitive similarities, one of which is an elevated risk for reading deficit. Our aim was to determine the influence of mood versus behavioral dysregulation on reading ability and neural correlates supporting these skills in youth, using diffusion tensor imaging in 11- to 17-year-old children and youths with mood disorders or behavioral disorders and age-matched healthy controls. The three groups differed only in phonological processing and passage comprehension. Youth with mood disorders scored higher on the phonological test but had lower comprehension scores than children with behavioral disorders and controls; control participants scored the highest. Correlations between fractional anisotropy and phonological processing in the left Arcuate Fasciculus showed a significant difference between groups and were strongest in behavioral disorders, intermediate in mood disorders, and lowest in controls. Correlations between these measures in the left Inferior Longitudinal Fasciculus were significantly greater than in controls for mood but not for behavioral disorders. Youth with mood disorders share a deficit in the executive-limbic pathway (Arcuate Fasciculus) with behavioral-disordered youth, suggesting reduced capacity for engaging frontal regions for phonological processing or passage comprehension tasks and increased reliance on the ventral tract (e.g., the Inferior Longitudinal Fasciculus). The low passage comprehension scores in mood disorder may result from engaging the left hemisphere. Neural pathways for reading differ mainly in executive-limbic circuitry. This new insight may aid clinicians in providing appropriate intervention for each disorder.

Educational and Health Status of 9-14 Year Old <750 gm Birthweight Children. ♦ 1189

Extremely low birthweight children (ELBW, <750 gm) who have survived since the 1980s are now entering adolescence. We compared the health and educational status of 56 ELBW (77% of survivors of a regional cohort born 1982-1986) to 51 750-1499 gm birthweight (VLBW) and 47 normal birthweight(NBW) children who were seen twice at mean ages of 6 and 11 years. At 6 years 8(14%) ELBW vs. 2 (4%) VLBW had neurosensory deficits, and 12 (21%) ELBW vs. 3(6%) VLBW vs. no NBW children had an IQ <70 (Kaufman MPC).
