    Executive Functioning and Learning Skills of Adolescent Children Born at Fewer than 26 Weeks of Gestation2016Ingår i: PLOS ONE, E-ISSN 1932-6203, Vol. 11, nr 3, artikel-id e0151819Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aims To assess the cognitive and behavioral aspects of executive functioning (EF) and learning skills in extremely preterm (EPT) children compared with term control children aged 10 to 15 years. Methods A total of 132 of 134 (98% of all eligible survivors) EPT children born at the 2 Swedish regional tertiary care centers from 1992 to 1998 (mean age = 12 years, mean birth weight = 718 g, and mean gestational age = 24.4 weeks) and 103 matched term controls were assessed. General intelligence was assessed using the Wechsler Intelligence Scale for Children (WISC-III-R), and cognitive aspects of EF were analyzed using EF-sensitive sub-scales of the WISC-III-R and Tower test of the Delis-Kaplan Executive Function Scale (D-KEFS). Behaviors related to EF and learning skills were assessed using the Five to Fifteen questionnaire, which is a validated parent and teacher instrument. Academic performance in school was assessed by teachers' responses on Achenbach's Teachers Report Form. Analyses performed included multivariate analyses of covariance (ANCOVA and MANCOVA) and logistic regression analyses. Results The EPT children displayed significant deficits in cognitive aspects of EF compared with the controls, exhibiting decreases on the order of 0.9 SD to 1.2 SD for tasks of verbal conceptual reasoning, verbal and non-verbal working memory, processing speed and planning ability (P < 0.001 for all). After excluding the children with major neurosensory impairment (NSI) or a Full Scale intelligence quotient (FSIQ) of < 70, significant differences were observed on all tests. Compared with controls, parents and teachers of EPT children reported significantly more EF-related behavioral problems. MANCOVA of teacher-reported learning skills in children with FSIQ > 70 and without major NSI revealed no interactions, but significant main effects were observed for the behavioral composite executive function score, group status (EPT vs control) and FSIQ, for which all effect sizes were medium to large. The corresponding findings of MANCOVA of the parent-reported learning skills were very similar. According to the teachers' ratings, the EPT children were less well adjusted to the school environment. Conclusion EPT children born in the 1990s who received active perinatal care are at an increased risk of executive dysfunction, even after excluding children with significant neurodevelopmental disabilities. Even mild to moderate executive dysfunctions has a significant impact on learning skills. These findings suggest the need for timely interventions that address specific cognitive vulnerabilities and executive dysfunctions.

    Chronic Conditions and Health Care Needs of Adolescents Born at 23 to 25 Weeks' Gestation2017Ingår i: Pediatrics, ISSN 0031-4005, E-ISSN 1098-4275, Vol. 139, nr 2, artikel-id e20162215Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: We examined chronic conditions, functional limitations, and special health care needs in extremely preterm children (EPT; 23-25 weeks' gestation) born between 1992 and 1998 at 2 Swedish tertiary care centers that offered regional and active perinatal care to all live-born EPT infants. METHODS: Of 134 surviving EPT children, 132 (98%) were assessed at 10 to 15 years of age alongside 103 term-born controls. Identification of children with functional limitations and special health care needs was based on a questionnaire administered to parents. Categorization of medical diagnoses and developmental disabilities was based on child examinations, medical record reviews, and parent questionnaires. RESULTS: In logistic regression analyses adjusting for social risk factors and sex, the EPT children had significantly more chronic conditions than the term-born controls, including functional limitations (64% vs 6%; odds ratio [OR], 15; 95% confidence interval [CI], 6.1-37.2; P < .001), compensatory dependency needs (60% vs 29%; OR, 3.8; 95% CI, 2.2-6.6; P < .001), and services above those routinely required by children (64% vs 25%; OR, 5.4; 95% CI, 3.0-9.6; P < .001). Specific diagnoses and disabilities for the EPT group versus controls included cerebral palsy (9.1% vs 0%; P < .001), asthma (21.2% vs 6.8%; P = 001), IQ < -2 SD (31.1% vs 4.9%; P < .001), poor motor skills without neurosensory impairment (21.9% vs 1.9%; P < .001), and psychiatric conditions (15.2% vs 1.9%; P < .001). CONCLUSIONS: Adolescents born EPT have considerable long-term health and educational needs. Few had severe impairments that curtailed major activities of daily life.

    Two-thirds of adolescents who received active perinatal care after extremely preterm birth had mild or no disabilities2016Ingår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 105, nr 11, s. 1288-1297Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: Active perinatal care (APC) increases the survival of extremely preterm (EPT) infants, but may increase the rate of disabilities. We examined neurodevelopmental outcomes in adolescents aged 10-15 years who were born EPT and received APC in two Swedish tertiary care centres.

    Methods: Cognitive function was assessed using the Wechsler Intelligence Scale for Children, and neurosensory impairments were assessed by reviewing the case records and a standard parent health questionnaire. The outcomes were compared to term-born controls.

    Results: We assessed 132 EPT adolescents and 103 controls. The rates of cerebral palsy, moderate to severe visual impairment and moderate to severe hearing impairment were 9%, 4% and 6%, respectively, for the EPT children and zero for the controls. Serious cognitive impairment was present in 31% of the EPT adolescents and 5% of the controls. Combining impairments across domains showed that 34% of EPT adolescents had moderate and severe disabilities compared with 5% of the controls. Impairments were more common at 23-24 weeks of gestational age (43%) than at 25 weeks (28.4%).

    Conclusion: Two-thirds (66%) of adolescents born EPT who received APC had mild or no disabilities. Our results are relevant for healthcare providers and clinicians counselling families.

    Behavioral Patterns in Adolescents Born at 23 to 25 Weeks of Gestation2017Ingår i: Pediatrics, ISSN 0031-4005, E-ISSN 1098-4275, Vol. 140, nr 1, artikel-id e20170199Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: This study examined mental health outcomes in extremely preterm children (EPT) born at 23 to 25 weeks of gestation between 1992 and 1998 at 2 Swedish tertiary care centers that offered regional and active perinatal care to all live-born EPT infants. METHODS; We assessed 132 (98%) of the 134 EPT survivors at 10 to 15 years of age alongside term-born controls. Behavioral and emotional problems were evaluated by using Achenbach's Child Behavior Checklist and Teacher Report Form and Conners' Parent and Teacher scales for attention-deficit/hyperactivity disorder. RESULTS: Parents and teachers reported significantly more problems with internalizing behaviors as well as attention, social, and thought problems in EPT children than in controls, even when those with major neurodevelopmental disabilities (NDDs) were excluded. Multivariate analysis of covariance of the behavioral problems reported by parents and teachers revealed no interactions, hut significant main effects emerged for group status (EPT versus control) and sex, with all effect sizes being medium to large and accounting for 8% to 14% of the variance. Compared with the controls, EPT children without NDDs had significantly increased rates of >= 90th percentile for total Conners' attention-deficit/hyperactivity disorder problem scores (parents: 40% vs 15%, odds ratio: 3.7, P <.001) (teachers: 24% vs 9%, odds ratio: 3.3, P =.005). The corresponding rates were higher in the total population. CONCLUSIONS: EPT children with or without NDDs had behavioral problems characterized by a higher risk for anxiety and attention, social, and thought problems. These findings further strengthen the proposition that a preterm behavioral phenotype is recognizable in adolescents born EPT.

    Neurodevelopment and growth until 6.5 years of infants who consumed a low-energy, low-protein formula supplemented with bovine milk fat globule membranes: a randomized controlled trial2021Ingår i: American Journal of Clinical Nutrition, ISSN 0002-9165, E-ISSN 1938-3207, Vol. 113, nr 3, s. 586-592Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: We previously reported results from a randomized controlled trial in which we found that Swedish infants consuming an experimental low-energy, low-protein formula (EF) supplemented with bovine milk fat globule membranes (MFGMs) until 6 mo of age had several positive outcomes, including better performance in the cognitive domain of Bayley Scales of Infant and Toddler Development 3rd Edition at 12 mo of age, and higher plasma cholesterol concentrations during the intervention, than infants consuming standard formula (SF).

    OBJECTIVES: We aimed to evaluate neurodevelopment, growth, and plasma cholesterol status at 6 and 6.5 y of age in the same study population.

    METHODS: We assessed cognitive and executive functions using the Wechsler Intelligence Scale for Children 4th Edition (WISC-IV), Brown Attention-Deficit Disorder Scales for Children and Adolescents (Brown-ADD), and Quantified Behavior (Qb) tests, and behavior using the Child Behavior Checklist (CBCL) and Teacher's Report Form (TRF), at 6.5 y of age. Anthropometrics and plasma lipids were assessed at 6 y of age.

    RESULTS: There were no differences between the EF and SF groups in any of the subscales in WISC-IV or Brown-ADD at 6.5 y of age, in the proportion of children with scores outside the normal range in the Qb test, nor in clinical or borderline indications of problems in adaptive functioning from parental and teacher's scoring using the CBCL and TRF. There were no differences between the EF and SF groups in weight, length, or head or abdominal circumferences, nor in plasma concentrations of homocysteine, lipids, insulin, or glucose.

    CONCLUSIONS: Among children who as infants consumed a low-energy, low-protein formula supplemented with bovine MFGMs, there were no effects on neurodevelopment, growth, or plasma cholesterol status 6-6.5 y later.

    Parents of extremely and moderately preterm children reported long-lasting impressions of medical care and the hospital environment2020Ingår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 109, nr 9, s. 1772-1777Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: Few studies have examined the parents of moderately preterm children. The aim of this study was to investigate the experiences of parents of both extremely and moderately preterm children. 

    Methods: Qualitative telephone interviews were conducted in 2013-2014 with 13 mothers and 10 fathers of extremely preterm children and with 11 mothers and seven fathers of moderately preterm children. The children were born between 2000 and 2003. Data were analysed with a narrative approach. 

    Results: Parents of extremely preterm children recounted dramatic birth stories that, for most, ended positively. Parents of moderately preterm children presented more neutral birth stories, and most recounted that their children did not receive attention for prematurity from medical staff. Parents from both groups described staff mem-bers’ treatment in terms of long-lasting impressions, and they were deeply affected by the hospital environment and the other parents and children admitted. Parents whose children died or were disabled recounted dramatic stories and endless fights for support. 

    Conclusion: Parents from both groups reported long-lasting impressions of the medi-cal staff and the hospital environment, which they found important to talk about, even a decade after the birth of their child/children.
