Behavioral Outcomes of Extremely Low Birth Weight Children at Age 8 Years

Objective: To describe the prevalence of behavioral problems and symptomatology suggestive of Autism and Aspergers disorders at age 8 years among extremely low birth weight (ELBW, <1 kg) children, born 1992 through 1995. Method: Parent reports of the behavior of 219 ELBW (mean birth weight, 810 g; gestational age 26 weeks) were compared with 176 normal birth weight children of similar maternal sociodemographic status, sex, and age. Behavior was assessed via the Child Symptom Inventory that includes both Symptom Severity Scores and scores meeting DSM-IV criteria for disorders. Results: ELBW compared with normal birth weight children had significantly higher mean Symptom Severity Scores for the inattentive, hyperactive, and combined types of attention-deficit hyperactivity disorder (all p < .001) as well as higher scores for Generalized Anxiety (p < .01) and Autistic (p < .001) and Aspergers (p < .01) disorders. When DSM-IV criteria were considered, ELBW children also had significantly higher rates of attention-deficit hyperactivity disorder of the inattentive (10% vs 3%, p < .01) and combined (5% vs 0.6%, p < .05) types. Conclusions: Attention-deficit hyperactivity disorder, mainly the inattentive type is prevalent among ELBW children. Our findings of an increase in symptoms pertaining to Autistic and Aspergers disorders at school age agree with recent reports of others during early childhood. Early identification and intervention for these problems might improve child functioning and ameliorate parent and child distress.

Academic achievement of adolescents born with extremely low birth weight.

Aim:  To assess academic achievement, rates of learning disabilities (LD) and special education in extremely low birth weight (ELBW <1 kg) adolescents relative to normal birth weight (NBW) controls and to identify cognitive weaknesses.

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.

Change in Prevalence of Chronic Conditions Between Childhood and Adolescence Among Extremely Low-Birth-Weight Children

CONTEXT Extremely low-birth-weight (ELBW) children have high rates of chronic conditions during childhood. Information on their trajectory of health during adolescence is needed for health care planning. OBJECTIVE To examine changes in the rates of chronic conditions between the ages of 8 and 14 years among ELBW children compared with normal-birth-weight (NBW) controls. DESIGN, SETTING, AND PARTICIPANTS Cohort study conducted from 2004 through 2009 of 181 ELBW children (weight < 1 kg) and 115 NBW controls of similar sociodemographic status born from 1992 through 1995 in Cleveland, Ohio. MAIN OUTCOME MEASURES Rates of chronic conditions overall (measured with the revised Questionnaire for Identifying Children With Chronic Conditions) and rates of asthma and obesity. RESULTS The overall rates of chronic conditions did not change significantly between the ages of 8 and 14 years among ELBW children (75% at age 8 years vs 74% at age 14 years) or NBW controls (37% at age 8 years vs 47% at age 14 years). In generalized estimating equations logistic regression adjusting for sociodemographic status, sex, and race, ELBW children continued to have a higher rate of chronic conditions than NBW controls at age 14 years (74% vs 47%, respectively, adjusted odds ratio [AOR], 2.8 [95% confidence interval {CI}, 1.7 to 4.6]). Rates of asthma requiring medication did not change between the ages of 8 and 14 years among ELBW children (23% at both ages) but increased among NBW controls from 8% at age 8 years to 17% at age 14 years (P = .002). Differences in rates of asthma between ELBW and NBW children were no longer significant at the age of 14 years (23% vs 17%, respectively; AOR, 1.5 [95% CI, 0.8 to 2.8]). Mean z scores for body mass index increased in ELBW children from 0.06 at age 8 years to 0.38 at age 14 years (P <.001) and rates of obesity increased from 12% at age 8 years to 19% at age 14 years (P = .02). However, the scores and rates did not change among NBW controls such that at the age of 14 years the differences between ELBW and NBW children in mean z scores for body mass index (0.38 vs 0.56, respectively; adjusted mean difference -0.2 [95% CI, -0.5 to 0.1]) or rates of obesity (19% vs 20%, respectively; AOR, 1.1 [95% CI, 0.6 to 2.0]) were not significant. CONCLUSIONS Among ELBW children, rates of overall chronic conditions and asthma did not change between the ages of 8 and 14 years but the rate of obesity increased. Compared with NBW controls, the rates of chronic conditions were higher but there were no significant differences in the rates of asthma or obesity.

Parental protection of extremely low birth weight children at age 8 years

Objective: To examine parent protection and its correlates among 8-year-old ELBW children compared with normal birth weight (NBW) controls. Methods: The population included 217 eight-year-old ELBW children born 1992–1995 (92% of the surviving birth cohort; mean birth weight, 811 g; mean gestational age, 26.4 weeks) and 176 NBW controls. The primary outcome measure, the Parent Protection Scale (PPS), included a total score and four domains including Supervision, Separation, Dependence, and Control. Multivariate analyses were performed to examine the predictors of parental protection and overprotection. Results: After adjusting for socioeconomic status (SES), race, sex, and age of the child, parents of ELBW children reported significantly higher mean total Parent Protection Scale scores (31.1 vs 29.7, p = .03) than parents of NBW children and higher scores on the subscale of Parent Control (8.0 vs 7.5, p = .04). These differences were not significant when the 36 children with neurosensory impairments were excluded. Parents of ELBW children also reported higher rates of overprotection than controls (10% vs 2%, p = .001), findings that remained significant even after excluding children with neurosensory impairments (8% vs 2%, p = .011). Multivariate analyses revealed lower SES to be associated with higher total Parent Protection Scale scores in both the ELBW (p < .001) and NBW (p < .05) groups. Additional correlates included neurosensory impairment (p < .05) and functional limitations (p < .001) in the ELBW group and black race (p < .05) and maternal depression (p < .01) in the NBW group. Lower child IQ was significantly associated with higher PPS scores only in the neurosensory impaired subgroup of ELBW children. Conclusions: Longer term follow-up will be necessary to examine the effects of the increased parent protection on the development of autonomy and interpersonal relationships as the children enter adolescence.

Bullying of extremely low birth weight children: associated risk factors during adolescence.

BACKGROUND Preterm children have many risk factors which may increase their susceptibility to being bullied. AIMS To examine the prevalence of bullying among extremely low birth weight (ELBW, <1 kg) and normal birth weight (NBW) adolescents and the associated sociodemographic, physical, and psychosocial risk factors and correlates among the ELBW children. METHODS Cohort study of self-reports of bullying among 172 ELBW adolescents born 1992-1995 compared to 115 NBW adolescents of similar age, sex and sociodemographic status. Reports of being bullied were documented using the KIDSCREEN-52 Questionnaire which includes three Likert type questions concerning social acceptance and bullying. Multiple linear regression analyses adjusting for sociodemographic factors were used to examine the correlates of bullying among the ELBW children. RESULTS Group differences revealed a non-significant trend of higher mean bullying scores among ELBW vs. NBW children (1.56 vs. 1.16, p=0.057). ELBW boys had significantly higher bullying scores than NBW boys (1.94 vs. 0.91, p<0.01), whereas ELBW and NBW girls did not differ (1.34 vs. 1.30, p=0.58). Bullying of ELBW children was significantly associated with subnormal IQ, functional limitations, anxiety and ADHD, poor school connectedness, less peer connectedness, less satisfaction with health and comfort, and less risk avoidance. CONCLUSION ELBW boys, but not girls, are more likely to be victims of bullying than NBW boys. School and health professionals need to be aware of the risk of bullying among ELBW male adolescents.

Self-Reported Adolescent Health Status of Extremely Low Birth Weight Children Born 1992–1995

OBJECTIVES: To compare the self-reported health of extremely low birth weight (ELBW, <1 kg) adolescents with that of normal birth weight (NBW) controls and the children’s assessments of their general health at ages 8 versus 14 years. METHODS: One hundred sixty-eight ELBW children and 115 NBW controls of similar gender and sociodemographic status completed the Child Health and Illness Profile–Adolescent Edition at age 14 years. It includes 6 domains: Satisfaction, Comfort, Resilience, Risk Avoidance, Achievement, and Disorders. At age 8 years, the children had completed the Child Health and Illness Profile–Child Edition. Results were compared between ELBW and NBW subjects adjusting for gender and sociodemographic status. RESULTS: ELBW adolescents rated their health similar to that of NBW adolescents in the domains of Satisfaction, Comfort, Resilience, Achievement and Disorders but reported more Risk Avoidance (effect size [ES] 0.6, P < .001). In the subdomain of Resilience, they also noted less physical activity (ES −0.58, P < .001), and in the subdomain of Disorders, more long-term surgical (ES −0.49) and psychosocial disorders (ES −0.49; both P < .01). Both ELBW and NBW children reported a decrease in general health between ages 8 and 14 years, which did not differ significantly between groups. CONCLUSIONS: ELBW adolescents report similar health and well-being compared with NBW controls but greater risk avoidance. Both ELBW and NBW children rate their general health to be poorer at age 14 than at age 8 years, possibly due to age-related developmental changes.

Persisting behavior problems in extremely low birth weight adolescents.

Objective:To describe behavior problems in extremely low birth weight (ELBW, <1000 g) adolescents born 1992 through 1995 based on parent ratings and adolescent self-ratings at age 14 years and to examine changes in parent ratings from ages 8–14. Method:Parent ratings of behavior problems and adolescent self-ratings were obtained for 169 ELBW adolescents (mean birth weight 815 g, gestational age 26 wk) and 115 normal birth weight (NBW) controls at 14 years. Parent ratings of behavior at age 8 years were also available. Behavior outcomes were assessed using symptom severity scores and rates of scores above DSM-IV symptom cutoffs for clinical disorder. Results:The ELBW group had higher symptom severity scores on parent ratings at age 14 years than NBW controls for inattentive attention-deficit hyperactivity disorder (ADHD), anxiety, and social problems (all ps < .01). Rates of parent ratings meeting DSM-IV symptom criteria for inattentive ADHD were also higher for the ELBW group (12% vs 1%, p < .01). In contrast, the ELBW group had lower symptom severity scores on self-ratings than controls for several scales. Group differences in parent ratings decreased over time for ADHD, especially among females, but were stable for anxiety and social problems. Conclusions:Extremely low birth weight adolescents continue to have behavior problems similar to those evident at a younger age, but these problems are not evident in behavioral self-ratings. The findings suggest that parent ratings provide contrasting perspectives on behavior problems in ELBW youth and support the need to identify and treat these problems early in childhood.

Health Status of Extremely Low-Birth-Weight Children at 8 Years of Age: Child and Parent Perspective

OBJECTIVES To compare the self-reported health of extremely low-birth-weight (ELBW; <1 kg) preterm children with that of normal-birth-weight (NBW) control children and the childrens perspective with that of their parents. DESIGN We administered questionnaires to the ELBW and NBW children and their parents from March 1, 2000, through February 2003. SETTING A childrens hospital. PARTICIPANTS Two hundred two ELBW children and 176 NBW children aged 8 years of similar sociodemographic status. MAIN EXPOSURE Birth weight of less than 1 kg. MAIN OUTCOME MEASURES The Child Health and Illness Profile-Child Edition child and parent reports. RESULTS There was poor agreement between the parent and child ratings of health for the ELBW and NBW cohorts. The ELBW children rated their health as similar to that of NBW children. In contrast, parents of ELBW children reported significantly poorer health for their children than parents of NBW controls, including poorer satisfaction with health, comfort, and achievement and less risk avoidance. CONCLUSIONS There is poor agreement between child and parent reports of health. At 8 years of age, ELBW children rate their health as similar to that of NBW controls. Their parents, however, report significantly poorer health. Both perspectives need to be considered when making health care decisions.

Trajectory and correlates of growth of extremely-low-birth-weight adolescents

Background:Catch-up growth may predispose to obesity and metabolic sequelae. We sought to examine the trajectory and correlates of growth and catch up among extremely-low-birth-weight (ELBW) (<1 kg) adolescents.Methods:A cohort study of 148 neurologically normal ELBW children and 115 normal-birth-weight (NBW) controls born during the period 1992–1995 was conducted. Longitudinal measures of gender-specific growth of ELBW children from birth, in addition to growth and measures of obesity of ELBW and NBW children at 14 y, were evaluated.Results:Following neonatal growth failure, ELBW children had accelerated growth, but at 8 y, they still had lower weight and height z scores than NBW children. By 14 y, ELBW boys had caught up in growth to their NBW controls, but ELBW girls remained significantly smaller. ELBW children, however, did not differ from their controls in measures of obesity. In hierarchical multiple regression analyses, only maternal BMI and weight gain during infancy and childhood predicted the ELBW children’s 14-y weight z scores, BMI z scores, and abdominal circumference. Perinatal risk factors, including intrauterine growth, only predicted growth up to 20 mo.Conclusion:Maternal BMI and rate of growth, rather than perinatal factors, predict 14-y obesity among neurologically normal ELBW adolescents.
