Neonatal predictors of cognitive ability in adults born very preterm : a prospective cohort study
Aim:
To identify neonatal predictors to allow a developmental prognosis of the cognitive abilities of survivors born very preterm/very low birthweight (VLBW) into adult life.
Method:
The Bavarian Longitudinal Study is a prospective whole-population study that followed 260 infants born very preterm/VLBW from birth to adulthood. Regression analyses examined which neonatal factors predicted adult IQ.
Results:
Neonatal morbidity, neonatal treatment, and early social environment of infants born very preterm/VLBW explained 37.6% of the variance in adult IQ. Seven unique early-life predictors of lower adulthood IQ were found: respiratory distress syndrome, intraventricular haemorrhage, problems with mobility, mechanical ventilation, less parenteral nutrition, low/middle socioeconomic status, and poor early parent–infant relationships. Specifically, modifiable factors such as mechanical ventilation predicted a drop of 0.43 IQ points for each day of treatment, adjusted for initial respiratory problems. Good early parent–infant relationships predicted an approximately 5-point increase in adult IQ, adjusted for other significant predictors such as socioeconomic status.
Interpretation:
Mechanical ventilation, parenteral feeding, and early parenting were identified as significant modifiable factors that were strongly related to adult IQ. Mechanical ventilation policies have changed but there is scope for early interventions that focus on positive parenting, which may reduce the adverse effects of very preterm/VLBW birth on cognitive abilities
Attention problems in very preterm children from childhood to adulthood : the Bavarian longitudinal study
Background:
Very preterm (VP; gestational age <32 weeks) and very low birth weight (VLBW; <1500 grams) is related to attention problems in childhood and adulthood. The stability of these problems into adulthood is not known.
Methods:
The Bavarian Longitudinal Study is a prospective cohort study that followed 260 VP/VLBW and 229 term-born individuals from birth to adulthood. Data on attention were collected at 6, 8, and 26 years of age, using parent reports, expert behavior observations, and clinical ADHD diagnoses.
Results:
At each assessment, VP/VLBW individuals had significantly more attention problems, shorter attention span, and were more frequently diagnosed with ADHD than term-born comparisons. In both VP/VLBW and term-born individuals, overall, attention span increased and attention problems decreased from childhood to adulthood. Attention problems and attention span were more stable over time for VP/VLBW than term-born individuals. Similarly, ADHD diagnoses showed moderate stability from childhood to adulthood in VP/VLBW, but not in term-born individuals. However, when those with severe disabilities were excluded, differences between VP/VLBW and term-born individuals reduced.
Conclusions:
Despite improvement in attention regulation from childhood to adulthood, children born very preterm remained at increased risk for attention problems in adulthood. In contrast, term-born children with clinical attention problems outgrew these by adulthood. As inattentive behavior of VP/VLBW children may be overlooked by teachers, it may be necessary to raise awareness for school intervention programs that reduce attention problems in VP/VLBW children
Psychopathological outcomes of adolescent borderline personality disorder symptoms
Objective: Despite considerable morbidity and functional losses associated with adolescent Borderline Personality Disorder (BPD), little is known about psychopathological outcomes. This study examined associations between adolescent BPD symptoms and subsequent depressive, psychotic, and hypomanic symptoms.
Methods: We used data from the Avon Longitudinal Study of Parents and Children. Participants were adolescents living in the community who had data for all longitudinal outcomes (N=1758). We used logistic regression and path analysis to investigate associations between BPD (5 or more probable/definite symptoms) reported at age 11-12 years and depressive and psychotic symptoms reported at age 12 and 18, and lifetime hypomanic symptoms reported at age 22-23 years.
Results: Adolescent BPD symptoms were associated with psychotic symptoms (OR: 2.36, CI: 1.82-3.06) and diagnosis of depression at age 18 years (OR: 1.30, CI: 1.03-1.64), and hypomanic symptoms (OR: 2.89, CI: 2.40-3.48) at 22-23 years. Path analysis controlling for associations between all outcomes, indicated that BPD symptoms were independently associated with depressive symptoms (β=0.97, p<.001) at 12 years and hypomanic (β=0.58, p<.01) symptoms at 22-23 years. BPD symptoms were also associated with psychotic symptoms at age 12 years (β=0.58, p<.01), which were linked (β =0.34, p<0.01) to psychotic symptoms at age 18 years.
Conclusion: Adolescents with BPD symptoms are at future risk of psychotic and hypomanic symptoms, and a diagnosis of depression. Future risk is independent of associations between psychopathological outcomes, indicating that adolescent BPD symptoms have multifinal outcomes. Increasing awareness of BPD in early adolescence could facilitate timely secondary prevention of these symptoms subsequently helping to prevent future psychopathology
Maternal mental health and adverse birth outcomes
Recent research in economics emphasizes the role of in utero conditions for the health endowment at birth and in early childhood and for social as well as economic outcomes in later life. This paper analyzes the relation between maternal mental health during pregnancy and birth outcomes of the child. In particular, we analyze the relationship between maternal mental health during pregnancy and the probability of giving birth preterm (PT), having a newborn at low birth weight (LBW) or being small for gestational age (SGA). Based on large population-representative data from the German Socio-Economic Panel (SOEP) and cohort data from the National Educational Panel Study (NEPS), we present extensive descriptive evidence on the relationship between maternal mental health and preterm birth by carrying out OLS estimates controlling for a wide range of socioeconomic characteristics. In addition, we apply matching estimators and mother fixed effects models, which bring us closer toward a causal interpretation of estimates. In summary, the results uniformly provide evidence that poor maternal mental health is a risk factor for preterm birth and low birth weight in offspring. In contrast, we find no evidence for an relationship between maternal mental health and small for gestational age at birth.Peer reviewe

Preschool Mathematics and Literacy Skills and Educational Attainment in Adolescents Born Preterm and Full Term
Objectives: To test whether preschool academic skills were associated with educational attainment in adolescence and whether associations differed between individuals born preterm and at full term. Study design: This prospective cohort study comprised 6924 individuals, including n = 444 (6.4%) adolescents born preterm ( .05). Higher preschool academic skill scores in mathematics were associated with greater odds of attaining GCSE Mathematics and preschool literacy skills were associated with GCSE English. Adolescents born preterm with higher preschool mathematics (OR: 1.51, CI: 1.14, 2.00) and literacy skills (OR: 1.57, CI: 1.10, 2.25) were more likely to attain GCSEs in the respective subject than their term-born counterparts with equal levels of preschool skills. Conclusions: Preschool academic skills in mathematics and literacy are associated with educational attainment of preterm and term-born individuals in adolescence. Children born prematurely may benefit more from preschool mathematics and literacy skills for academic and educational success into adolescence than term-born individuals
Mathematics difficulties in extremely preterm children : evidence of a specific deficit in basic mathematics processing
Background:
Extremely preterm (EP, <26 wk gestation) children have been observed to have poor academic achievement in comparison to their term-born peers, especially in mathematics. This study investigated potential underlying causes of this difficulty.
Methods:
A total of 219 EP participants were compared with 153 term-born control children at 11 y of age. All children were assessed by a psychologist on a battery of standardized cognitive tests and a number estimation test assessing children’s numerical representations.
Results:
EP children underperformed in all tests in comparison with the term controls (the majority of Ps < 0.001). Different underlying relationships between performance on the number estimation test and mathematical achievement were found in EP as compared with control children. That is, even after controlling for cognitive ability, a relationship between number representations and mathematical performance persisted for EP children only (EP: r = 0.346, n = 186, P < 0.001; control: r = 0.095, n = 146, P = 0.256).
Conclusion:
Interventions for EP children may target improving children’s numerical representations in order to subsequently remediate their mathematical skills
Effect of maternal panic disorder on mother-child interaction and relation to child anxiety and child self-efficacy
To determine whether mothers with panic disorder with or without agoraphobia interacted differently with their children than normal control mothers, 86 mothers and their adolescents (aged between 13 and 23 years) were observed during a structured play situation. Maternal as well as adolescent anxiety status was assessed according to a structured diagnostic interview. Results showed that mothers with panic disorder/agoraphobia showed more verbal control, were more criticizing and less sensitive during mother-child interaction than mothers without current mental disorders. Moreover, more conflicts were observed between mother and child dyadic interactions when the mother suffered from panic disorder. The comparison of parenting behaviors among anxious and non-anxious children did not reveal any significant differences. These findings support an association between parental over-control and rejection and maternal but not child anxiety and suggest that particularly mother anxiety status is an important determinant of parenting behavior. Finally, an association was found between children’s perceived self-efficacy, parental control and child anxiety symptoms
Infant regulatory problems, parenting quality and childhood attention problems
Background and aims
To determine the combined impact of infant multiple/persistent regulatory problems (RPs), parenting quality and maternal mental health on childhood attention problems.
Study design
A prospective, population-based cohort study including 16 paediatric hospitals in Southern Bavaria (Germany).
Subjects
1459 infants were followed from birth to 8 years of age.
Outcome measures
RPs were assessed at 5 and 20 months using interviews by trained paediatricians; parenting quality was assessed between birth and 5 months using parent interviews and nurses' observations; maternal mental health was assessed at birth and 5 months using standardized parents' interviews; childhood data on attention problems were collected at 8 years, using parent reports and expert behaviour observation ratings.
Results
After correction for gestational age, sex, and socioeconomic status, early RPs (β = 0.079) and low parenting quality (β = 0.175) predicted later attention problems (R2 = 0.272). Their impact was additive, such that infants with both multiple/persistent RPs and poor parenting quality showed the highest attention problems 8 years later. However, the impact of RPs on attention was strongest for preterm children. Maternal mental health was a significant moderator of the relationship between parenting quality and attention problems. With adequate maternal mental health, good parenting quality was related to lower attention problems, yet with mental health problems present, the effect of good parenting on attention problems diminished.
Conclusions
Guidance and support for parents of infants with multiple/persistent crying, sleeping or feeding problems may be essential to prevent the development of childhood attention problems, especially when maternal mental health problems are present
Educational outcomes in extremely preterm children : neuropsychological correlates and predictors of attainment
This study assessed the impact of extremely preterm birth on academic attainment at 11 years of
age, investigated neuropsychological antecedents of attainment in reading and mathematics, and
examined early predictors of educational outcomes. Children born extremely preterm had significantly
poorer academic attainment and a higher prevalence of learning difficulties than their term
peers. General cognitive ability and specific deficits in visuospatial skills or phoneme deletion at 6
years were predictive of mathematics and reading attainment at 11 years in both extremely preterm
and term children. Phonological processing, attention, and executive functions at 6 years were also
associated with academic attainment in children born extremely preterm. Furthermore, social factors,
neonatal factors (necrotizing enterocolitis, breech delivery, abnormal cerebral ultrasound, early
breast milk provision), and developmental factors at 30 months (head circumference, cognitive development),
were independent predictors of educational outcomes at 11 years. Neonatal complications
combined with assessments of early cognitive function provide moderate prediction for educational
outcomes in children born extremely preterm
