Maternal sensitivity in early childhood and body mass index in adolescence: A population-based study on the role of self-regulation as a mediator

Maternal sensitivity has been implicated in various aspects of child health and development, including overweight. However, long-term effects, the role of paternal sensitivity and the explanatory pathways are unclear. This study examined whether maternal sensitivity in early childhood is prospectively associated with adolescent body mass index and whether children's self-regulation mediates this relation. Data from 540 children and their mothers were available from a large cohort study in the Netherlands. Maternal sensitivity was assessed at child ages 1, 3, and at 4 years paternal sensitivity was also included. Children's self-regulation skills were observed at age 3, eating behaviour was assessed at 10 years, and child BMI was measured at 13 years. Longitudinal structural equation modelling was applied. The cross-sectional association between maternal sensitivity and child self-regulation was significant, while lower levels of self-regulation and higher levels of food responsiveness and restrained eating predicted a higher child BMI at 13 years. Furthermore, a direct association of paternal sensitivity at 4 years with BMI at 13 years was found, but only in girls. Maternal sensitivity was not directly associated with child BMI after adjusting for covariates. Our findings showed the importance of self-regulation in the early years for subsequent weight development. Nevertheless, as self-regulation could not explain the relationship between parenting and child weight, research should focus on the contribution of other contextual factors, such as feeding styles and the social environment, to this relationship.The general design of Generation R Study is made possible by financial support from the Erasmus Medical Center and the Erasmus University Rotterdam, the Netherlands Organization for Health Research and Development (ZonMW), the Netherlands Organisation for Scientific Research (NWO), the Ministry of Health, Welfare and Sport and the Ministry of Youth and Families.

Bayesian evidence synthesis in case of multi-cohort datasets:An illustration by multi-informant differences in self-control

Abstract The trend toward large-scale collaborative studies gives rise to the challenge of combining data from different sources efficiently. Here, we demonstrate how Bayesian evidence synthesis can be used to quantify and compare support for competing hypotheses and to aggregate this support over studies. We applied this method to study the ordering of multi-informant scores on the ASEBA Self Control Scale (ASCS), employing a multi-cohort design with data from four Dutch cohorts. Self-control reports were collected from mothers, fathers, teachers and children themselves. The available set of reporters differed between cohorts, so in each cohort varying components of the overarching hypotheses were evaluated. We found consistent support for the partial hypothesis that parents reported more self-control problems than teachers. Furthermore, the aggregated results indicate most support for the combined hypothesis that children report most problem behaviors, followed by their mothers and fathers, and that teachers report the fewest problems. However, there was considerable inconsistency across cohorts regarding the rank order of children’s reports. This article illustrates Bayesian evidence synthesis as a method when some of the cohorts only have data to evaluate a partial hypothesis. With Bayesian evidence synthesis, these cohorts can still contribute to the aggregated results

Dose response of the 16p11.2 distal copy number variant on intracranial volume and basal ganglia

Carriers of large recurrent copy number variants (CNVs) have a higher risk of developing neurodevelopmental disorders. The 16p11.2 distal CNV predisposes carriers to e.g., autism spectrum disorder and schizophrenia. We compared subcortical brain volumes of 12 16p11.2 distal deletion and 12 duplication carriers to 6882 non-carriers from the large-scale brain Magnetic Resonance Imaging collaboration, ENIGMA-CNV. After stringent CNV calling procedures, and standardized FreeSurfer image analysis, we found negative dose-response associations with copy number on intracranial volume and on regional caudate, pallidum and putamen volumes (β = −0.71 to −1.37; P < 0.0005). In an independent sample, consistent results were obtained, with significant effects in the pallidum (β = −0.95, P = 0.0042). The two data sets combined showed significant negative dose-response for the accumbens, caudate, pallidum, putamen and ICV (P = 0.0032, 8.9 × 10⁻⁶, 1.7 × 10⁻⁹, 3.5 × 10⁻¹² and 1.0 × 10⁻⁴, respectively). Full scale IQ was lower in both deletion and duplication carriers compared to non-carriers. This is the first brain MRI study of the impact of the 16p11.2 distal CNV, and we demonstrate a specific effect on subcortical brain structures, suggesting a neuropathological pattern underlying the neurodevelopmental syndromes

Psychopathology in the adolescent offspring of bipolar parents

Background: The aim of this study was to determine the prevalence and 14-months incidence of psychopathology in adolescent offspring of a bipolar parent. Method: Parent, teacher and self-report rating scales and Kiddie-SADS were used to assess 132 13-23-year-old offspring of bipolar parents. Results: Compared to the general population, there were few differences between rating scale scores for bipolar offspring and problem scores for normative adolescents. Of the sample 49% had a lifetime psychiatric disorder, most commonly (33%) a mood disorder. Limitations: There was no suitable control group and there are no comparison data for psychiatric diagnoses (DSM-IV), based on semi-structured interviews in the adolescent age group in the Netherlands. Conclusions: The overall level of psychopathology of bipolar offspring was not particularly elevated, but when there were more problems, they tended to be mood disorders. (C) 2002 Elsevier B.V.

Prevalence of psychopathology in children of a bipolar parent

Objective: To determine psychopathology in adolescent children of a bipolar parent living In the Netherlands, using multiple sources of information (self-, parent, and teacher reports). Method: Problem behavior in 140 offspring (aged 12-21 years) of 86 bipolar parents was assessed with the Child Behavior Checklist (CBCL), the Teachers Report Form (TRF), and the Youth Self-Report (YSR) between 1997 and 1999. All adolescents, bipolar parents, and their available spouses were interviewed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). Results: Higher problem scores were found for 8 of the 11 CBCL scales for girls and 4 of the 11 CBCL scales for boys, compared with a Dutch normative sample, and 1 Young Adult Self-Report (YASR) scale for girls compared with an American normative sample. Lower problem scores were found on 4 YSR and 4 YASR scales for boys, 1 TRF scale for girls, and 1 TRF scale for boys. The prevalence of current DSM-IVdiagnoses in the offspring was 29% and of lifetime DSM-IV diagnoses, 44%. Conclusions: The prevalence of problem behavior and DSM-IVdiagnoses found in our sample did not support the notion that the level of psychopathology in children aged 12 to 21 years of bipolar parents is highly elevated. This study, similar to prior studies, suffers from lack of information on the representativeness of the sample and a rather low response rate
