Stimulation beliefs, parental reading involvement, and social inequalities in children's language development

Objective: This study investigates whether greater identification of mothers and fathers in different-sex couples with the stimulation dimension of intensive parenting promoted both parents' involvement in reading and benefited children's language development between ages 3 and 5 in the UK. In addition, we explore social class variations. Background: Our study tests the frequently assumed relationship of parenting beliefs about stimulation with language development, and contributes to our understanding of parenting practices and their implications for child development. Method: We draw on a large representative sample of young children from the UK Millennium Cohort Study (N = 8,071) and apply path analyses in the framework of structural equation models. Results: For mothers and fathers, stimulation beliefs partially mediated the relation between parental education and reading frequency. Mothers' and fathers' stimulation beliefs had positive effects on children’s language abilities, but their impact was small compared to the direct associations with parental education. Conclusion: While parental education emerges as a key determinant of children's language development, our study reveals the nuanced role of beliefs about stimulation within intensive parenting, prompting further investigation into the multifaceted nature of parental involvement.

Electronic device usage among preschool children and its association with mental health status in Saudi Arabian kindergartens.

To estimate the prevalence of electronic device usage and its association with mental health status among preschool children aged 3-6 years. A cross-sectional study was conducted among preschool children aged 3-6 years in kindergartens in Makkah city in 2023-2024, using an electronic questionnaire. An Arabic version of the Strengths and Difficulties Questionnaire was used to assess mental health. We recruited a total of 399 children. The prevalence of electronic device usage was 91.5%. The number of hours spent using electronic devices ranged from 0 to 12 hour (h)/day, with a mean of 3.1h/day. We found a significant positive correlation between the number of hours spent using electronic devices and emotional problems (r=0.200, p<0.001), conduct problems (r=0.149, p=0.003), hyperactivity (r=0.279, p<0.001), peer problems (r=0.104, p=0.038), and total difficulty scores (r=0.263, p<0.001). We also found a significant negative correlation between the number of hours spent using electronic devices and the prosocial score (r= -0.128, p=0.011), and most of the included children had scores within the "close to average" category across all scales of mental health status. There was a high prevalence of electronic device usage among preschool children, which exceeded the recommended time limit. A significant correlation was observed between electronic device use and mental health scores. Further longitudinal studies are required to understand the nature of this association and its implications for child development.

Young Children &amp; Implicit Racial Biases

Abstract Children are not born harboring racial biases, but they are born learning. Young children, even infants, learn from the “mere observation” of other people's behavior. Nonverbal signals of racial biases are abundant in children's everyday social environments. Studies show that preschool children acquire social group biases when they observe other people's social interactions and nonverbal behaviors. These new findings have implications for child development and educational equity. Even before kindergarten, racial biases are caught even when not explicitly taught, suggesting the need for practical actions for parents, teachers, and others concerned about the transmission of racial bias across generations.

Relationships between levels of endocrine-disrupting chemicals and immune markers in maternal circulation during mid-pregnancy

Background and Aim: Prenatal exposure to endocrine-disrupting chemicals (EDCs) has been linked to child neurodevelopmental disorders. Maternal immune activation during pregnancy is associated with adverse child developmental outcomes. Whether EDCs influence maternal immune physiology is unclear. Methods: We analyzed data from general population controls (n=439) of the Early Markers for Autism (EMA) Study, a case-control study of children born during 2000-2003 in Southern California. Eleven polychlorinated biphenyls (PCBs), 6 brominated flame retardants (BFRs), 2 organochlorine pesticides (OCPs), 6 polyfluoroalkyl substances (PFAS), and 22 cytokines/chemokines were measured in maternal serum samples collected 15-20 weeks into pregnancy. We assessed individual relationships between log-transformed EDC levels and immune markers with spearman correlations and adjusted linear regression models. We further explored overall associations of EDC mixtures with specific immune markers using Bayesian kernel machine regression (BKMR). Results: After adjustment for false-discovery rate, 28 correlations between EDCs and maternal immune markers were statistically significant (spearman rho ranging from -0.25 to 0.24). These top correlations comprised 14 chemicals (9 PCBs, 3 PFAS, 1 BFR, and 1 OCP), and 8 immune markers. In adjusted linear models, all PCBs were inversely associated with levels of soluble interleukin-2 receptor alpha (sIL-2ra), with PCB99 showing the strongest relationship (adj-β[95%CI]: -0.48[-0.69, -0.27]). In BKMR, increasing all congeners in the PCB mixture from their 50th to their 95th percentiles was associated with decreased sIL-2ra (adj-β[95%CrI]: -0.43[-0.84, -0.02] and PCB99 had the highest relative importance in this mixture. Among other EDCs, p,p´-DDE, an OCP, was inversely associated with multiple markers (IL-12p40, IL-13, and IL-1ra). In contrast, others, such as Et-FOSAA, a PFAS, were positively associated with multiple immune markers, including IL-12p70, GM-CSF, IL-1ra, and IL-10. Conclusions: These findings suggest that specific EDCs may affect diverse immune and inflammatory pathways during pregnancy. These relationships may have implications for child development.

Impacts of the COVID-19 pandemic on the child care sector: Evidence from North Carolina

This study provides a comprehensive, census-level evaluation of the impacts of the COVID-19 pandemic on the county child care market in a large and diverse state, North Carolina, and the disproportionate impacts of the pandemic on different types of providers and communities. We use county-level panel data from 2016 to 2020 and a difference-in-differences design to isolate the effects of the pandemic from unobservable seasonal trends in enrollments and closures. We found that the COVID-19 pandemic reduced county-level child care enrollment by 40% and the number of providers by 2% as of December 2020. Heterogeneity analyses revealed that the family child care sector experienced not only less severe reductions in enrollment and closure than center providers, but also a small growth in the number of family providers. Declines in enrollment were most substantial for preschool-aged children. There was a significant drop in the number of 5-star providers and an increase in the number of lower-quality providers. Provider closures were more concentrated in communities with a higher percentage of Hispanic residents. Higher-SES communities experienced larger drops in enrollment as well as provider closures. Implications for child development and future research and policies are discussed.

Maternal alexithymic traits are related to lower maternal sensitivity and higher hostility in mother-infant interaction

Background A child’s ability to regulate emotions, attention and arousal develops in the context of their primary caregiving from the very beginning of infancy and thus, is dependent on bidirectional signalling and understanding of emotions also within mother-infant interaction. Parental alexithymia could potentially complicate this emotional interaction. In this study, we aim to explore the association between maternal alexithymic traits and the quality of mother-infant interaction. Methods The study sample consisted of 158 mother-infant dyads within the FinnBrain Birth Cohort Study population who had filled in a questionnaire measuring alexithymic traits 6 months postpartum and participated in an observational study on mother-infant interaction 8 months postpartum. Alexithymia was measured with the 20-item Toronto Alexithymia Scale including all three alexithymia dimensions – Difficulty Identifying Feelings (DIF), Difficulty Describing Feelings (DDF) and Externally Oriented Thinking (EOT). Mother-infant interaction was assessed with the Emotional Availability Scale and in this study all four adult dimensions (Sensitivity, Structuring, Non-intrusiveness and Non-hostility) were included. The associations were studied with correlation analyses and General Linear Model. Results Maternal alexithymic traits were associated with the quality of mother-infant interaction. Specifically, the association between DDF and Sensitivity (p = 0.044, η 2 p = 0.026) and EOT and Non-hostility (p = 0.030, η 2 p = 0.030) remained significant when controlled by associated background and confounding factors. Conclusions Support was found for the hypothesis that higher maternal alexithymic traits would associate with weaker maternal sensitivity and more hostile behavior in mother-infant interaction. Further studies are needed to gain support for these hypotheses and to investigate their possible implications for child development.

Maternal Alexithymic Traits Are Related to Lower Maternal Sensitivity and Higher Hostility in Maternal Caregiving Behavior—The FinnBrain Birth Cohort Study

Background: The quality of parental caregiving behavior with their child plays a key role in optimal mother–infant interaction and in supporting child adaptive development. Sensitive caregiving behavior, in turn, requires the ability to identify and understand emotions. Maternal alexithymia, with difficulties in identifying and describing feelings or emotions, as well as a concrete way of thinking, could potentially complicate the quality of caregiving. In this study, we aim to explore the possible association between maternal alexithymic traits and the quality of maternal caregiving behavior.Methods: The study sample consisted of 158 mother–infant dyads within the FinnBrain Birth Cohort Study population with an available report of maternal alexithymic traits at 6 months postpartum and observational data on maternal caregiving behavior at 8 months postpartum. Alexithymia was measured using the 20-item Toronto Alexithymia Scale (TAS-20) including three alexithymia dimensions—Difficulty Identifying Feelings, Difficulty Describing Feelings (DDF), and Externally Oriented Thinking (EOT). Maternal caregiving behavior was assessed using the Emotional Availability Scale and in this study, all four parent dimensions (Sensitivity, Structuring, Non-intrusiveness and Non-hostility) were included. Maternal depressive and anxiety symptoms at 6 months postpartum were controlled for as potential confounders. In addition, background factors of mother's age and gestational weeks at the time of child birth, maternal educational level, monthly income and parity, as well as relationship status and the gender of the baby were assessed.Results: Maternal TAS-20 total score correlated negatively with Sensitivity (r = −0.169, p = 0.034) and with non-intrusiveness (r = −0.182, p = 0.022). In addition, maternal DDF correlated negatively with Sensitivity (r = −0.168, p = 0.035) and EOT with Non-hostility (r = −0.159, p = 0.047). Furthermore, in regression analyses with controlling for the associated background factors, maternal total score of alexithymic traits (p = 0.034, η2p = 0.029) and higher DDF (p = 0.044, η2p = 0.026) remained significantly associated with lower Sensitivity and higher EOT remained significantly associated with lower Non-hostility (p = 0.030, η2p = 0.030).Conclusions: In this explorative study we found preliminary evidence for the hypothesis that higher maternal alexithymic traits associate with lower maternal sensitivity and more hostile maternal caregiving behavior. Further studies are needed to explore these hypotheses and to investigate their possible implications for child development.

Parental well-being in times of Covid-19 in Germany

We examine the effects of Covid-19 and related restrictions on individuals with dependent children in Germany. We specifically focus on the role of day care center and school closures, which may be regarded as a “disruptive exogenous shock” to family life. We make use of a novel representative survey of parental well-being collected in May and June 2020 in Germany, when schools and day care centers were closed but while other measures had been relaxed and new infections were low. In our descriptive analysis, we compare well-being during this period with a pre-crisis period for different groups. In a difference-in-differences design, we compare the change for individuals with children to the change for individuals without children, accounting for unrelated trends as well as potential survey mode and context effects. We find that the crisis lowered the relative well-being of individuals with children, especially for individuals with young children, for women, and for persons with lower secondary schooling qualifications. Our results suggest that public policy measures taken to contain Covid-19 can have large effects on family well-being, with implications for child development and parental labor market outcomes.

Depressive symptoms disrupt leftward cradling

Objective: Leftward cradling bias is thought to facilitate optimal interaction between mother and infant. There is mixed evidence indicating this bias may be disrupted by depression. This study investigated the relationship between depressive symptoms and preferred cradling side (i.e., cradling bias) in nulliparous women. Method: Six hundred and nineteen females, aged 18 to 25 years, were asked to imagine cradling an infant to soothe it. This instruction was given on four separate occasions. Participants also completed the Beck Depression Inventory-II. All data were collected via an online survey. Results: As the number of depressive symptoms increased, leftward cradling decreased. Although this relationship was not statistically significant, a pattern emerged: As depressive symptoms increased, so too did the likelihood of cradling to the right. Furthermore, those scoring highest on depressive symptoms were more likely to cradle inconsistently to the left, consistently to the right, or show no bias, when compared to those scoring lower on depressive symptoms. Conclusions: Theory suggests that leftward cradling is facilitated by right hemisphere processes involved in relating to others. A relationship between affective symptoms such as depressive symptoms and reduced leftward cradling bias supports this argument. It is argued that leftward cradling facilitates optimal interactions between cradler and infant. Consequently, disruptions of leftward cradling have implications for child development.

Parental Well-Being in Times of COVID-19 in Germany

Mother’s Height and Calcium Intake Against Stunting among Children Aged 3-5 Years and The Impact on Child Development -

The purpose of this study was to identify the impacts of the mother's height and calcium intake on the incidence of stunting and the implications for child development. It was a cross-sectional study and involved about 78 children aged 3-5 years old from three early childhood education programs in Darul Imarah Sub-district, Aceh Besar District, Indonesia. Chi-square was performed to determine the correlation of the mother's height and calcium intake against the incidence of stunting, and impact of stunting on child development. The results showed that the height of mother (OR=4.0; 95% CI: 1.05 – 15.12) and calcium intake (OR=4.6; 95% CI: 1.37 – 15.69) had a significant correlation to the incidence of stunting, while to the child's development (OR=2.5; 95% CI: 0.82 – 8.11) had no significant impacts. This study could be one of the fundamental basic about the importance of nutritional intake in each life cycle so that the mother's height could be maximized.

Experiência da maternidade e Indicadores Clínicos de Risco para o Desenvolvimento Infantil (IRDIs)

O objetivo do presente artigo foi verificar as repercussões da experiência materna na interação mãe-filho, examinando suas implicações para o desenvolvimento da criança por meio dos IRDIs em uma amostra de mães de bebês nascidos em cidade de porte médio e arredores da região central do Rio Grande do Sul (RS). A amostra do estudo foi composta por díades mães - bebê (n=165) em Hospital Escola. Para a coleta de dados foi utilizado um roteiro de entrevista para investigar informações socioeconômicas, demográficas, obstétricas, psicossociais e a experiência materna. Também foi utilizado os Indicadores Clínicos de Risco para o Desenvolvimento Infantil (IRDIs). Quando se avaliou a associação entre a ausência/presença de risco para os bebês (IRDIs) e a ausência/presença de alteração emocional materna, encontrou-se resultado significativo. Há maior proporção de bebês com risco quando a mãe apresenta alteração emocional no período pós-parto.

Multiple-Partner Fertility and Cohort Change in the Prevalence of Half-Siblings.

The transformation of the American family under the second demographic transition has created more opportunities for parents to have children with multiple partners, but data limitations have hampered prevalence estimates of multiple-partner fertility from the perspective of children. This study uses nationally representative data from the 1979 and 1997 cohorts of the National Longitudinal Surveys of Youth to examine cohort change in children's exposure to multiple-partner fertility. We find that one in five children in the 1979 cohort had at least one half-sibling by their 18th birthday, and the prevalence grew to more than one in four children by the 1997 cohort. A strong educational gradient in exposure to half-siblings persists across both cohorts, but large racial/ethnic disparities have narrowed over time. Using demographic decomposition techniques, we find that change in the racial/ethnic and socioeconomic composition of the U.S. population cannot explain the growth in exposure to half-siblings. We conclude by discussing the shifting patterns of fertility and family formation associated with sibling complexity and considering the implications for child development and social stratification.

Sex and poverty modify associations between maternal peripartum concentrations of DDT/E and pyrethroid metabolites and thyroid hormone levels in neonates participating in the VHEMBE study, South Africa

Indoor Residual Spraying (IRS), the application of insecticides on the inside walls of dwellings, is used by 84 countries for malaria control. Although effective in preventing malaria, this practice results in elevated insecticide exposure to >100 million people, most of whom are Africans. Pyrethroid insecticides and dichlorodiphenyl trichloroethane (DDT) are currently used for IRS. Animal and in vitro studies suggest that pyrethroids and DDT interfere with thyroid hormone homeostasis but human studies are inconsistent and no prior study has investigated this question in a population residing in an area where IRS is conducted. Our objective was thus to evaluate whether prenatal exposure to pyrethroids, DDT or DDT's breakdown product dichlorodiphenyl dichloroethylene (DDE) is associated with altered thyroid hormone levels among neonates from Limpopo, South Africa, where pyrethroids and DDT are used annually to control malaria. We measured serum DDT/E and urinary pyrethroid metabolite concentrations in maternal peripartum samples from 717 women participating in the Venda Health Examination of Mothers, Babies and their Environment (VHEMBE), a birth cohort study conducted in Limpopo's Vhembe district. We measured total thyroxine (T4) and thyroid-stimulating hormone (TSH) in dried blood spots collected via heel stick. We found that all pyrethroid metabolites were positively associated with TSH; trans-DCCA and 3-PBA showed the strongest associations with a 12.3% (95%CI = 3.0, 22.3) and 14.0% (95%CI = 0.5, 30.2) change for each 10-fold increase in biomarker concentration, respectively. These associations were substantially stronger among children from households below the South African food poverty line. DDT and DDE were associated with lower total T4 among boys only (β = −0.27 μg/dL per 10-fold increase; 95%CI = −0.47, −0.04). Results suggest that prenatal exposure to DDT, DDE and pyrethroid insecticides is associated with changes in neonatal thyroid hormones consistent with hypothyroidism/hypothyroxinemia and that sex and poverty modify associations. Further research is needed to confirm these findings and examine whether they have implications for child development.

Parent-carer awareness and understanding of dyspraxia: Implications for child development support practices

Dyspraxia manifests as difficulty in thinking, planning, and executing planned movements or tasks. Dyspraxia affects roughly 5–6% of school aged children. This study aimed to explore parent-carer’s awareness and understanding of dyspraxia and the resources they self-perceived to need to manage their children with dyspraxia. Informants were 15 parents from the Cape Peninsula, South Africa. They completed semi-structured interviews on their knowledge of and indicators of dyspraxia in their children and resources they presently utilised or could seek to use. Thematic analysis of the data suggested the parent-carers to be aware of motor rather than cognition oriented limitations. Additionally, parent-carers accessed or sought educator assistance from the school system. Health professionals and educators working with parents of children with dyspraxia can expect them to report reliably on behavioural characteristics of their children’s abilities important for treatment support interventions.

Longitudinal association of child maltreatment and cognitive functioning: Implications for child development.

Although research investigating associations among child maltreatment, cognitive functioning, and academic achievement has grown in recent years, important questions remain. In particular, assessing the influence of maltreatment apart from that of other co-occurring and confounding factors remains difficult. This study was developed to further the field's understanding by investigating cognitive functioning in association with time-variant maltreatment patterns. Using multiple time-variant linear mixed models, we investigated the relationships between maltreatment timing and three domains of cognitive functioning (i.e., knowledge, comprehension, and analysis). In general, the cognitive functioning of students who experienced maltreatment was lower than that of their peers who had yet to experience maltreatment at the time of testing. Results of LMM indicated that the cognitive functioning of students who experienced maltreatment concurrent with the testing year fluctuated over time whereas the cognitive functioning of students who experienced maltreatment prior to or after the testing year remained stable. Students who experienced concurrent maltreatment showed the lowest functioning of any group. While maltreatment timing was a significant predictor of cognitive functioning over time, the addition of poverty into the model resulted in a non-significant effect of maltreatment timing. Additional research is needed to disentangle the longitudinal effect of maltreatment on cognitive functioning and address the interacting role of poverty and chronic maltreatment.

The development of cross-cultural recognition of vocal emotion during childhood and adolescence

Humans have an innate set of emotions recognised universally. However, emotion recognition also depends on socio-cultural rules. Although adults recognise vocal emotions universally, they identify emotions more accurately in their native language. We examined developmental trajectories of universal vocal emotion recognition in children. Eighty native English speakers completed a vocal emotion recognition task in their native language (English) and foreign languages (Spanish, Chinese, and Arabic) expressing anger, happiness, sadness, fear, and neutrality. Emotion recognition was compared across 8-to-10, 11-to-13-year-olds, and adults. Measures of behavioural and emotional problems were also taken. Results showed that although emotion recognition was above chance for all languages, native English speaking children were more accurate in recognising vocal emotions in their native language. There was a larger improvement in recognising vocal emotion from the native language during adolescence. Vocal anger recognition did not improve with age for the non-native languages. This is the first study to demonstrate universality of vocal emotion recognition in children whilst supporting an “in-group advantage” for more accurate recognition in the native language. Findings highlight the role of experience in emotion recognition, have implications for child development in modern multicultural societies and address important theoretical questions about the nature of emotions.

Knowing what others know: Linking deception detection, emotion knowledge, and Theory of Mind in preschool

AbstractChildren's ability to understand and infer the thoughts and feelings of others influences how they develop a unique view of the world. Examining developmental factors that impact young children's success in both social and cognitive domains has important implications for advancing our current knowledge of social cognition. The purpose of this study was to examine relations among emotion knowledge, deception detection, and Theory of Mind to shed light on the development of social cognition. Specifically, preschoolers' deception detection skills were found to moderate the relationship between emotion knowledge and Theory of Mind. Thus, children's ability to use their emotion knowledge to understand the points of view of others varies as a function of their ability to detect deception. Implications for child development are discussed.Highlights The purpose of this study was to examine relations among emotion knowledge, deception detection, and Theory of Mind.
