Politicians, parents, educators, health care specialists, lawyers, judges, clinical psychologists, all claim to have this goal in mind, and some even seem to think they are the only one. But what exactly is child well-being? It is easier to say what child well-being is not: risky adolescent behaviour, unhealthy lifestyle, drug addiction, disrupted parent–child relationships, and so forth. Can we then conclude that the absence of negative things constitutes well-being? Certainly not. In this chapter, we will discuss the current use and meaning of well-being in the context of child and adolescent development with a focus on methodological requirements for indicators informing policymakers and community leaders. It is important to acknowledge the difference between results of political decisions (e.g., the establishment of a health care system, providing institutions for day care, or passing laws allowing parental leave), which we label output variables, and the effects such decisions have on child well-being. We argue in favour of using child-oriented data indicating developmental progress as the essential basis for the evaluation of such investments.

Previous studies mostly focused on the infancy of preterms but did not examine the development process. This study highlights whether preterm children and their main caregivers still differ in their emotional availability (EA) at preschool age. Caregiver-child interactions during the transition period of school entry were measured with the Emotional Availability Scales (EAS). N = 25 preterm (25–33 weeks of gestation) and n = 23 term children at an age of 5 years and their main caregivers were observed while playing a construction game that was eliciting either a low or moderate stress level. Caregivers of preterm children showed higher intrusiveness scores compared to caregivers of term dyads. Thus, it seems that parents of preterm children behave intrusively independently of their children's cognitive performance.

Epigenetics, Sep 16, 2021

Prenatal exposure to endocrine disrupting chemicals can interfere with development, and has been ... more Prenatal exposure to endocrine disrupting chemicals can interfere with development, and has been associated with social-cognitive functioning and adverse health outcomes later in life. Exposure-associated changes of DNA methylation (DNAm) patterns have been suggested as a possible mediator of this relationship. This study investigated whether prenatal low-dose exposure to polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) is associated with altered DNAm patterns across the genome in a Western urban-industrial population. In 142 mother-infant pairs from the Duisburg Birth Cohort Study, PCBs and PCDD/Fs levels were quantified from maternal blood during late pregnancy and associated with DNAm levels in cord blood using the Illumina EPIC beadchip. The epigenome-wide association studies (EWAS) identified 32 significantly differentially methylated positions (DMPs) and eight differentially methylated regions (DMRs) associated with six congeners of PCB and PCDD in females or males (FDRs < 0.05). DMPs and DMRs mapped to genes involved in neurodevelopment, gene regulation, and immune functioning. Weighted gene correlation network analysis (WGCNA) showed 31 co-methylated modules (FDRs < 0.05) associated with one congener of PCDF levels in females. Results of both analytical strategies indicate that prenatal exposure to PCBs and PCDD/Fs is associated with altered DNAm of genes involved in neurodevelopment, gene expression and immune functioning. DNAm and gene expression levels of several of these genes were previously associated with EDC exposure in rodent models. Follow-up studies will clarify whether these epigenetic changes might contribute to the origin for adverse mental and health outcomes.

Schlafprobleme und eine unzureichende Schlafdauer können die psychische Gesundheit im Kindes- und Jugendalter nachhaltig beeinträchtigen. Daten von 6.670 Jungen und Mädchen im Alter von 11 – 13 und 14 – 17 Jahren, aus dem Kinder- und Jugendgesundheitssurvey (KIGGS), wurden getrennt nach Geschlechtern analysiert, um zu untersuchen, ob Schlafprobleme und eine unzureichende Schlafdauer mit einer höheren Risikowahrscheinlichkeit für psychische Auffälligkeiten einhergehen. Während Schlafprobleme unabhängig von Geschlecht und Alter mit einem höheren Risiko für alle Symptombereiche (OR = 1.52 – 3.49) verbunden sind, findet sich hinsichtlich einer geringen Schlafdauer nur bei Mädchen eine höheres Risikowahrscheinlichkeit für Auffälligkeiten im externalisierenden und internalisierenden Bereich. Damit scheint sich der Zusammenhang zwischen unzureichender Schlafdauer und psychischen Auffälligkeiten bei Jungen und Mädchen zu unterscheiden. Mögliche Ursachen und Implikationen für die pädiatrische und psychiatrische Praxis werden diskutiert.

Die Bedenken gegen die Leihmutterschaft beziehen sich auf ihrerseits existenzstrittige psychologische Konzepte wie pranatale Bindungstheorie, oder auf durch Ausbeutung okonomischer Ungleichheit beruhende Formen der Leihmutterschaft entstehende Besonderheiten.

Untersucht wurde, ob sich 30 fruhgeborene (24.–34. Gestationswoche) und 25 reifgeborene Kinder (38.–41. Gestationswoche) im Alter von funf bis sechs Jahren zum Zeitpunkt des Schuleingangs in ihrer Bindungsqualitat unterschieden. Die Bindungsqualitat wurde auf der Ebene mentaler Reprasentationen durch das Geschichtenerganzungsverfahren zur Bindung 5–8 jahriger Kinder (GEV-B 5–8; Gloger-Tippelt und Konig 2009/2016) erfasst. Fruhgeborene wiesen mit 36.7% vs. 16.0% tendenziell haufiger desorganisierte Bindungsreprasentationen auf als Reifgeborene. Anhand der Befunde kann ein erhohtes Risiko fur desorganisierte Bindungen in der mittleren Kindheit nach einer Fruhgeburt angenommen werden.
