Neurodevelopment at Age 10 Years of Children Born <28 Weeks With Fetal Growth Restriction.

ABSTRACT: OBJECTIVES:We sought to evaluate the relationships between fetal growth restriction (FGR) (both severe and less severe) and assessments of cognitive, academic, and adaptive behavior brain function at age 10 years. METHODS:At age 10 years, the Extremely Low Gestational Age Newborns Cohort Study assessed the cognitive function, academic achievement, social-communicative function, psychiatric symptoms, and overall quality of life of 889 children born before 28 weeks' gestation. A pediatric epileptologist also interviewed parents as part of a seizure evaluation. The 52 children whose birth weight z scores were <-2 were classified as having severe FGR, and the 113 whose birth weight z scores were between -2 and -1 were considered to have less severe FGR. RESULTS:The more severe the growth restriction in utero, the lower the level of function on multiple cognitive and academic achievement assessments performed at age 10 years. Growth-restricted children were also more likely than their extremely preterm peers to have social awareness impairments, autistic mannerisms, autism spectrum diagnoses, difficulty with semantics and speech coherence, and diminished social and psychosocial functioning. They also more frequently had phobias, obsessions, and compulsions (according to teacher, but not parent, report). CONCLUSIONS:Among children born extremely preterm, those with severe FGR appear to be at increased risk of multiple cognitive and behavioral dysfunctions at age 10 years, raising the possibility that whatever adversely affected their intrauterine growth also adversely affected multiple domains of cognitive and neurobehavioral development.

Project description:BackgroundThe evolution of knowledge and technical advances in neonatal resuscitation have improved the survival of very premature babies. However, the long-term neurodevelopmental prognosis and cognitive and learning abilities are still uncertain.ObjectiveThis study aimed to evaluate the neurodevelopment and learning abilities of 7-year-old children born prematurely, and their parents' feelings at 8 years of age.Patients and methodsData from children born before 33 weeks gestation in a level III maternity hospital and involved in a regional follow-up network were analyzed at 7 years of age. Neurodevelopmental abnormalities were defined as cerebral palsy, hearing or visual impairment, and/or behavioral abnormalities. School performance was evaluated by the EDA test. A parents' questionnaire assessed their feelings about the child's and family's quality of life at 8 years of age.ResultsAt 7 years of age, 51% of the 238 children presented neurodevelopmental abnormalities: 3.3% with cerebral palsy, 6.2% with hearing impairments, 50.7% with visual impairments, and 11.3% with behavioral disorders. The children with neurodevelopmental abnormalities had lower gestational age (29.0 ± 2.0 vs. 30.0 ± 2.1 weeks, p = 0.003) and more EEG abnormalities during the neonatal period (31.1% vs. 19.8%, p = 0.048) than the children without abnormalities. Ninety-four percent of the children with abnormalities were enrolled in normal schools, 33% with special support. In the overall cohort, 31% of the children had all academic performance scores in the normal range of the reference population. At 8 years old, 39% of the parents of children with neurodevelopmental abnormalities felt that their child's situation significantly impacted their quality of life compared to 14% of parents of children without neurodevelopmental abnormality (p = 0.022).ConclusionHalf of children born very prematurely present with long-term neurodevelopmental abnormalities, which their parents feel significantly impacts their quality of life.

Project description:ObjectiveA neonatal illness severity score, The Score for Neonatal Acute Physiology-II (SNAP-II), predicts neurodevelopmental impairments at two years of age among children born extremely preterm. We sought to evaluate to what extent SNAP-II is predictive of cognitive and other neurodevelopmental impairments at 10 years of age.Study designIn a cohort of 874 children born before 28 weeks of gestation, we prospectively collected clinical, physiologic and laboratory data to calculate SNAP-II for each infant. When the children were 10 years old, examiners who were unaware of the child's medical history assessed neurodevelopmental outcomes, including neurocognitive, gross motor, social and communication functions, diagnosis and treatment of seizures or attention deficit hyperactivity disorder (ADHD), academic achievement, and quality of life. We used logistic regression to adjust for potential confounders.ResultsAn undesirably high SNAP-II (⩾30), present in 23% of participants, was associated with an increased risk of cognitive impairment (IQ, executive function, language ability), adverse neurological outcomes (epilepsy, impaired gross motor function), behavioral abnormalities (attention deficit disorder and hyperactivity), social dysfunction (autistic spectrum disorder) and education-related adversities (school achievement and need for educational supports. In analyses that adjusted for potential confounders, Z-scores ⩽-1 on 11 of 18 cognitive outcomes were associated with SNAP-II in the highest category, and 6 of 18 were associated with SNAP-II in the intermediate category. Odds ratios and 95% confidence intervals ranged from 1.4 (1.01, 2.1) to 2.1 (1.4, 3.1). Similarly, 2 of the 8 social dysfunctions were associated with SNAP-II in the highest category, and 3 of 8 were associated with SNAP-II in the intermediate category. Odds ratios and 95% confidence intervals were slightly higher for these assessments, ranging from 1.6 (1.1, 2.4) to 2.3 (1.2, 4.6).ConclusionAmong very preterm newborns, physiologic derangements present in the first 12 postnatal hours are associated with dysfunctions in several neurodevelopmental domains at 10 years of age. We are unable to make inferences about causality.

Project description:ImportancePreterm birth and low birth weight are associated with brain developmental and neurocognitive outcomes in childhood; however, not much is known about the specific critical periods in fetal life and infancy for these outcomes.ObjectiveTo examine the associations of fetal and infant growth patterns with brain morphology in children at school age.Design, setting, and participantsThis population-based, prospective cohort study was conducted from February 1 to April 16, 2021, as a part of the Generation R Study in Rotterdam, the Netherlands. The study included 3098 singleton children born between April 1, 2002, and January 31, 2006.ExposuresFetal weight was estimated in the second and third trimesters of pregnancy by ultrasonography. Infant weight was measured at birth and at 6, 12, and 24 months. Fetal and infant weight acceleration or deceleration were defined as a change in SD scores greater than 0.67 between time points. Infant measurements also included peak weight velocity, and age and body mass index reached at adiposity peak.Main outcomes and measuresBrain structure, including global and regional brain volumes, was quantified by magnetic resonance imaging at age 10 years.ResultsThe study evaluated 3098 children (mean [SD] age at follow-up, 10.1 [0.6] years; 1557 girls [50.3%]; and 1753 Dutch [57.8%]). One SD score-higher weight gain until the second and third trimesters, birth, and 6, 12, and 24 months was associated with larger total brain volume independently of growth during any other age windows (second trimester: 5.7 cm3; 95% CI, 1.2-10.2 cm3; third trimester: 15.3 cm3; 95% CI, 11.0-19.6 cm3; birth: 20.8 cm3; 95% CI, 16.4-25.1 cm3; 6 months: 15.6 cm3; 95% CI, 11.2-19.9 cm3; 12 months: 11.3 cm3; 95% CI, 7.0-15.6 cm3; and 24 months: 11.1 cm3; 95% CI, 6.8-15.4 cm3). Compared with children with normal fetal and infant growth, those with fetal and infant growth deceleration had the smallest total brain volume (-32.5 cm3; 95% CI, -53.2 to -11.9 cm3). Children with fetal weight deceleration followed by infant catch-up growth had similar brain volumes as children with normal growth. Higher peak weight velocity and body mass index reached at adiposity peak were associated with larger brain volumes. Similar results were observed for cerebral and cerebellar gray and white matter volumes.Conclusions and relevanceThis cohort study's findings suggest that both fetal and infant weight growth might be critical for cerebral and cerebellar brain volumes during childhood. Whether these associations link to neurocognitive outcomes should be further studied.
