Patterns of childcare arrangements and cognitive development

Objectives. The current study investigated (a) whether identifiable patterns of childcare arrangements from birth to 51 months exist and (b) whether these patterns moderate cognitive development from 18 months to 51 months in relation to maternal stimulation of language and infant difficult temperament controlling for SES and child gender. Methods. Of the 1201 who participated in the Families, Children Childcare Study, 978 were included in the current study. Data were collected when children were 3, 18, 36 and 51 months old regarding their mother-reported childcare arrangements, mother-reported child temperament and objective tests of cognitive and language abilities. Results. Six prevailing patterns of childcare arrangements were identified. Variations were found across these in predicting cognitive development. For all types, cognitive ability at 18 months influenced language ability at 36 months, which in turn influenced cognitive ability at 51 months. Cognitive scores at 18 months were directly and significantly influential on cognitive ability at 51 months only in the ‘maternal to centre-based care’ and ‘multi types’ patterns of childcare. Early and ongoing centre-based care predicted higher language ability at 36 months but its impact was not evident at 51 months. When girls entered centre-based care after they were 3 years old, their cognitive scores were negatively influenced. Low family SES was a risk factor for language ability at 36 months when children were not introduced to any non-parental care before the age of three years. Conclusion. This study helped to understand that the particular childcare pathway from birth to the start of school interacts with family and child factors to contribute to child cognitive outcomes at 51 months. This information should be relevant to families as they make decisions about when to start or stop different types of child care during infancy and preschool years

Training attention control of very preterm infants: protocol for a feasibility study of the Attention Control Training (ACT)

Background Children born preterm may display cognitive, learning, and behaviour difficulties as they grow up. In particular, very premature birth (gestation age between 28 and less than 32 weeks) may put infants at increased risk of intellectual deficits and attention deficit disorder. Evidence suggests that the basis of these problems may lie in difficulties in the development of executive functions. One of the earliest executive functions to emerge around 1 year of age is the ability to control attention. An eye-tracking-based cognitive training programme to support this emerging ability, the Attention Control Training (ACT), has been developed and tested with typically developing infants. The aim of this study is to investigate the feasibility of using the ACT with healthy very preterm (VP) infants when they are 12 months of age (corrected age). The ACT has the potential to address the need for supporting emerging cognitive abilities of VP infants with an early intervention, which may capitalise on infants’ neural plasticity. Methods/design The feasibility study is designed to investigate whether it is possible to recruit and retain VP infants and their families in a randomised trial that compares attention and social attention of trained infants against those that are exposed to a control procedure. Feasibility issues include the referral/recruitment pathway, attendance, and engagement with testing and training sessions, completion of tasks, retention in the study, acceptability of outcome measures, quality of data collected (particularly, eye-tracking data). The results of the study will inform the development of a larger randomised trial. Discussion Several lines of evidence emphasise the need to support emerging cognitive and learning abilities of preterm infants using early interventions. However, early interventions with preterm infants, and particularly very preterm ones, face difficulties in recruiting and retaining participants. These problems are also augmented by the health vulnerability of this population. This feasibility study will provide the basis for informing the implementation of an early cognitive intervention for very preterm infants. Trial registration Registered Registration ID: NCT03896490.

A trajectories of behavior, attention, social and emotional problems from childhood to early adulthood following extremely preterm birth: a prospective cohort study

© 2018, The Author(s). To investigate trajectories of behavior, attention, social and emotional problems to early adulthood in extremely preterm survivors compared to a term-born comparison group. Longitudinal analysis of a prospective, population-based cohort of 315 surviving infants born < 26 completed weeks of gestation recruited at birth in 1995, from the UK/Republic of Ireland, and a term-born comparison group recruited at age 6. The parent-report Strengths and Difficulties Questionnaire was completed at age 6, 11, 16 and 19 years. The Total Behavioral Difficulties Score was 4.81 points higher in extremely preterm individuals compared to their term-born peers over the period (95% CI 3.76–5.87, p < 0.001) and trajectories were stable in both groups. The impact of difficulties on home life, friendships, school or work and/or leisure activities was greater in the EPT group (RR 4.28, 95% CI 2.89–6.35, p < 0.001), and hyperactivity/inattention and peer problems accounted for the largest differences. A clinically significant behavioral screen at age 2.5 was associated with a higher Total Behavioral Difficulties Score from 6 years onwards in extremely preterm participants (Mean difference 6.90, 95% CI 5.01–8.70, p < 0.0.01), as was moderate/severe cognitive impairment at last assessment (Mean difference: 4.27, 95% CI 2.76–5.77, p < 0.001). Attention, social and emotional problems in extremely preterm individuals persist into early adulthood with significant impact on daily life. A positive behavioral screen in infancy and moderate/severe cognitive impairment are associated with early adult outcomes.NIHR Doctoral Research Fellowship, NIHRDRF-2012-05-206.

Behavioural and educational outcomes following extremely preterm birth : current controversies and future directions

As a consequence of improved survival rates for extremely preterm (EP; <28 weeks of gestation) births, there is a growing body of evidence detailing the impact of extreme prematurity on outcomes throughout childhood and adolescence. Historically, attention first focused on documenting rates of sensory impairments and severe neurodevelopmental disabilities. However, over recent years, there has been growing interest in the impact of EP birth on long term mental health and educational outcomes. In this chapter we review literature relating to the impact of EP birth on attention, social and emotional problems, psychiatric disorders and educational outcomes. We also outline current controversies in the field. In particular, we present emergent research exploring developmental trajectories to determine whether the sequelae associated with EP birth represent a developmental delay or persistent deficit, and we consider what approaches to intervention may be most fruitful in improving behavioural and educational outcomes in this population
