Adolescents' engagement profiles and their association with academic performance and situational engagement
2020
Abstract This study examined adolescents' engagement profiles and their association with situational engagement and academic performance in lower secondary school settings. The data consisted of 301 Grade 7 students from Finland. By utilizing person-oriented approach with Latent Profiling Analysis on subscales capturing students' overall engagement, four subgroups of students with different overall engagement profiles were identified. These profile groups were further analyzed with respect to differences in student background (gender and maternal education), academic performance (GPA, and reading and mathematics tests), and lesson-specific situational engagement. The profile groups showed d…
From prematurity to parenting stress: The mediating role of perinatal post-traumatic stress disorder
2013
Preterm delivery may lead to the emergence of symptoms of Post-Traumatic Stress disorder (PTSD), which may, in turn, affect the quality of the mother-child relationship. The aim of this study is to shed light on the development of parenting stress in mothers of preterm and full-term children. It is hypothesized that PTSD symptoms mediate the relationship between preterm/full-term birth and the levels of parenting stress. Perinatal PTSD, parenting stress and social support were assessed in 156 mothers of full-term children and 87 mothers of preterm children. Mothers of preterm children experienced more post-traumatic stress and parenting stress than mothers of full-term children. However, th…
The temporal dimension in the understanding of maternal sensitivity in caregiver-infant interactions: The 'Early Mother-Child Interaction Coding Syst…
2021
Abstract Caregiver-child interaction is known to play a central role in children’s socioemotional development, yet the diversity of measures commonly used to evaluate it call into question the nature of the construct being assessed. Contingency within caregiver-child interactions has been identified as a key dyadic process that requires taking a temporal perspective to evaluating interactions. The Early Mother-Child Interaction Coding System is a psychometrically sound measure that sequentially code the flow of interactive and non-interactive behaviours within a caregiver-infant system. Its use of the framework of nonlinear dynamical systems (NDS) expands our understanding of contingent car…
Responsive home numeracy as children progress from kindergarten through Grade 1
2020
The aim of the present study was to investigate longitudinal associations between formal home numeracy activities and children’s arithmetic fluency skills. Children were followed during the transition from the end of kindergarten (T1; Mage = 6.87 years) to the beginning of Grade 1 (T2), and again at the end of the Grade 1 (T3). Participants were Lithuanian children (n = 341) and their parents. At each time point, parents reported the frequency of the formal home numeracy activities they engaged in with their children; the children completed addition and subtraction tasks at the same three time points. Using a cross-lagged analysis, we found that parents adjusted the frequency of their home …
Prenatal exposure to perfluoroalkyl substances, immune-related outcomes, and lung function in children from a Spanish birth cohort study.
2019
Background: Prenatal exposure to perfluoroalkyl substances (PFASs) has been associated with impaired immune and respiratory health during childhood but the evidence is inconsistent and limited for lung function. We studied the association between prenatal PFASs exposure and immune and respiratory health, including lung function, up to age 7 years in the Spanish INMA birth cohort study. Methods: We assessed four PFASs in maternal plasma samples collected during the 1st trimester of pregnancy (years: 2003-2008): perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorononanoate (PFNA). Mothers reported the occurrence (yes/no) of lower respir…
Association of Thyroid Function Test Abnormalities and Thyroid Autoimmunity With Preterm Birth A Systematic Review and Meta-analysis
2019
Preterm birth complicates 5% to 15% of births worldwide, and although it is the most important direct cause of morbidity and mortality in children younger than 5 years, no known risk factors can be identified in the majority of cases. However, overt hypothyroidism and hyperthyroidism during pregnancy are well-known risk factors for preterm birth, and as such, the purpose of this study was to assess whether thyroid function test abnormalities and thyroid peroxidase (TPO) antibody positivity were associated with preterm birth. The study conducted a systematic review on the association of thyroid function or autoimmunity with preterm birth published from database inception to March 18, 2018, w…
Twenty-year trends in the prevalence of Down syndrome and other trisomies in Europe : impact of maternal age and prenatal screening
2013
This study examines trends and geographical differences in total and live birth prevalence of trisomies 21, 18 and 13 with regard to increasing maternal age and prenatal diagnosis in Europe. Twenty-one population-based EUROCAT registries covering 6.1 million births between 1990 and 2009 participated. Trisomy cases included live births, fetal deaths from 20 weeks gestational age and terminations of pregnancy for fetal anomaly. We present correction to 20 weeks gestational age (ie, correcting early terminations for the probability of fetal survival to 20 weeks) to allow for artefactual screening-related differences in total prevalence. Poisson regression was used. The proportion of births in …
Sosioøkonomisk status og mors kroppsmasseindeks er assosiert med varighet av delvis amming og fullamming av norske spedbarn : En tverrsnittsundersøke…
2017
Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2017 Objective: To explore whether there is an association between socioeconomic status and maternal body mass index, and duration of partial breastfeeding/exclusive breastfeeding of Norwegian infants in 2016. Design: Cross-sectional design. Baseline data from a randomized controlled trial, collected by a Food Frequency Questionnaire. Setting: Recruitment was done through Facebook and child health care centres in 2016. In total 1048 infants/parents were interested in participating in the study Early Food for Future Health. Subjects: A total of 715 infant/mother- dyads completed the questionnaire when the child was between 5 and…
Creativity in Middle Childhood: Influence of Perceived Maternal Sensitivity, Self-esteem, and Shyness
2016
This study aimed to examine the relationship between maternal sensitivity and affect, as perceived by the child, and childhood creativity. Self-esteem and shyness were considered mediating factors. A total of 151 elementary school pupils were tested on verbal and pictorial creativity, self-esteem, and perceived maternal affect and sensitivity. Their teachers assessed each child’s shyness in their relations at school. A Multiple Indicators and Multiple Causes (MIMIC) model of the causal relationships among the study’s variables was tested. Results supported this theoretical model of causality. Maternal sensitivity had a significant, direct, positive effect on self-esteem, and a direct negati…
Long-Term Administration of High Dose Vitamin A to Rats Does Not Cause Fetal Malformations: Macroscopic, Skeletal and Physicochemical Finds
1996
A rat model was used to investigate whether high oral doses of vitamin A lead to fetal malformations and to what extent retinyl esters (RES) are transferred from the mother to the fetuses. Retinol and RES concentrations in plasma behave similarly in rats and humans. When high concentrations of vitamin A are administered, plasma retinol concentrations remain relatively constant, whereas plasma RES increased in parallel with the dose. To achieve an elevation from approximately 150 to > 1525 nmol x L(-1) in the experimental group before mating, female Ibm: RORO (spf) rats were fed a maintenance diet enriched with 15.2 x 10(3) retinol equivalents (RE) x kg(-1) at the start and increased stepwis…
