Finger use mirroring young children's ways of experiencing numbers.

Children who encounter questions about quantities or numbers are observed to use their fingers in different ways to aid their problem solving. This study aimed to contribute to the area of finger counting research with an inquiry of what children's finger use tells us about their knowledge of numbers. A basic argument is that it is not sufficient to observe the actual use of fingers; there is a need for interpretations of what the finger use means to the children, taking the children's perspective as the outset. This was done by analyzing 4- and 5-year-olds' finger use through the lens of phenomenography and variation theory of learning to describe the qualitatively different ways in which children use fingers as an expression of their ways of experiencing the meanings of numbers. Five categories of finger use that show a variety in the meanings the fingers represent emerged: Fingers represent individual items, quantities, countables, number relations, and number structure. The results show that children's finger use may give access to their ways of understanding numbers; some ways of using fingers indicate expressions of more or less advanced meanings of numbers. A conclusion from the results is that to develop number knowledge and skills, children are aided by learning to see and use their fingers as representing composed units. Some children need the structural support of fingers to solve number problems, and fingers should be used to explore number structures rather than used as countables.

Effectiveness of glass-ionomer sealant versus fluoride varnish application to prevent occlusal caries among preschool children over 18-24 months - A randomised controlled trial.

OBJECTIVES: To compare the clinical efficacies of 5% sodium fluoride varnish (NaFV) and glass-ionomer sealant (GIS) in preventing occlusal caries in primary second molars (PSMs). MATERIALS AND METHODS: A total of 736 children were recruited from 18 kindergartens and randomised into either Group 1- receiving NaFV quarterly, or Group 2 - single placement of GIS at baseline. Interventions were performed on 1431 and 1264 PSMs in Group 1 and Group 2, respectively. The primary outcome was the development of ICDAS≥4 dentine caries at the occlusal surfaces of PSMs. RESULTS: A total of 736 children (383 in Group 1; 353 in Group 2) received the intervention. After 18-24 months, 479 children with 1764 PSMs were reviewed. Despite a low GIS retention rate of 2.4% by 18-24 months, only 17.1% of PSM in the GIS group developed caries into dentine. No significant difference was identified when compared to the proportion of PSMs with caries into dentine in the NaFV group (17.0%). Regression analysis with GEE revealed that only baseline dft score and plaque level had a significant influence on development of ICDAS≥4 dentine caries in PSMs. CONCLUSIONS: Quarterly-applied NaFV and a single placement of medium viscosity GIS have similar clinical efficacies in preventing occlusal caries among preschool children. CLINICAL SIGNIFICANCE: There is no significant difference between quarterly-applied NaFV and GIS in preventing occlusal caries at PSMs. Dental clinicians can choose to use either of these preventive methods after considering their own and parents' preferences, children's cooperation and other practical factors.

Risk of Severe Early Childhood Caries over Time in Low-Income Preschoolers.

INTRODUCTION: Early childhood caries (ECC), and the progression to severe ECC (S-ECC), is a serious oral health issue, leading to acute pain, sepsis, tooth loss, and compromised quality of life. Although the association between sociodemographic factors and ECC has been widely discussed, it remains unclear whether the same association exists between inequality and S-ECC. OBJECTIVES: To investigate the impact of low income on the oral health of preschool children and explore any additional risk factors for developing ECC and S-ECC during follow-up. METHODS: The study used Taipei Child Development Screening Program data from 2014 to 2019. It included children aged 3 to 5 y who had more than 2 oral exams and completed baseline oral health questionnaires. Low-income children were matched 1:4 with controls by age and gender. Evaluation of ECC and S-ECC used the dmft index during follow-up exams. Generalized estimating equations (GEEs) assessed the impact of household income on ECC and S-ECC risk over time. RESULTS: Of the 895 participants, 179 were from low-income households. We revealed a significantly higher risk of developing S-ECC (adjusted odds ratio [aOR] 1.99; 95% confidence interval [CI] 1.25-3.17) in children from low-income households, with no significantly increased of risk of developing ECC. Children who consumed sugary beverages >4 times per week showed elevated risks of developing both ECC (aOR 1.77; 95% CI 1.07-2.94) and S-ECC (aOR 1.89; 95% CI 1.13-3.17). Protective factors included children with mothers with a college education (S-ECC: aOR 0.50; 95% CI 0.32-0.79). CONCLUSION: Children from low-income households have a significant risk of developing S-ECC compared with children from non-low-income households during follow-up. Factors contributing to this risk include lower maternal education, poor maternal oral health, and increased consumption of sugar-sweetened beverages. Policymakers should develop health measures to reduce the prevalence of ECC and S-ECC in children from low-income households whose mothers have lower educational levels and poor oral health. KNOWLEDGE TRANSFER STATEMENT: The results of this study highlight the significant S-ECC risk among preschool children from low-income households in Taipei, with other risk factors including higher consumption of sugar-sweetened beverages, lower maternal education, and poor maternal oral health. Policymakers can use our findings to develop targeted policy and behavioral interventions to reduce S-ECC in vulnerable populations.

Impaired head circumference growth and behavioural problems in childhood: Longitudinal findings from the MINA-Brazil birth cohort.

BACKGROUND: Previous evidence on the relation between early head circumference (HC) growth and behavioural outcomes in preschoolers has been inconsistent. OBJECTIVE: We aimed to investigate whether HC growth from birth to 5 years of age was related to internalising or externalising behavioural problems at 5 years of age in a sex-specific manner. METHODS: Among 303 girls and 318 boys from the MINA-Brazil birth cohort, we examined the associations between changes in HC from birth to 5 years of age and internalising and externalising behaviour problem scores at 5 years according to the Strengths and Difficulties Questionnaire for parents. HC values were transformed into sex- and age-specific z-scores (HCZ) using World Health Organisation standards, and the differences between values at 5 years of age and birth were classified into quintiles. We estimated adjusted mean differences with 95% confidence intervals in behavioural problem scores between HCZ change quintiles using multivariable linear regression by sex. To examine nonlinear associations, we included cubic spline terms. RESULTS: Head circumference growth from birth to 5 years of age was inversely and nonlinearly associated with internalising problems in girls. Compared with girls at the lowest quintile of HC growth, those above had an adjusted 1.27 (95% confidence interval 0.28, 2.27) points lower mean internalising problems score. This association was mostly driven by HC growth during the first 2 years. We found no association between HC growth and externalising behaviour in either sex. CONCLUSIONS: Impaired HC growth was related to higher mean internalising problem scores at 5 years of age in girls but not in boys. HC growth was not associated with externalising problems.

Fundamental movement skills proficiency in preschool-aged boys and girls: Family matters.

To investigate the associations of fundamental movement skill (FMS) proficiency with family factors, including socioeconomic status (SES) and caregiver characteristics, by sex in young children in China. Participants included 1,207 Chinese children aged 3-6 years in this cross-sectional study. Children's FMS, consisting of locomotor skills and object control (OC) skills, were assessed. Information on family SES and caregiver characteristics was reported by the parents. Sex differences in outcomes and the associations of FMS with family factors by sex were examined using SPSS 26.0. Boys scored significantly higher than girls in terms of overall FMS and OC skills (both p < 0.01). There were significant and negative associations between children's FMS and parental education level and parental body mass index (BMI), which varied by sex. Boys who were regularly cared for by parents had higher FMS and OC skill scores than did those who were primarily looked after by grandparents (both p < 0.01). This complex interplay between sex and family factors (i.e. parental education level, parental BMI, and the identity of primary caregiver) on FMS proficiency in young children underscores the urgent need for developing sex-tailored, family-involved, and socio-culturally adapted interventions to enhance FMS proficiency at the preschool stage.

MINISTOP 3.0: Implementation of a mHealth obesity prevention program within Swedish child healthcare - study protocol for a cluster randomized controlled trial.

BACKGROUND: Previously, we have reported on the efficacy and real-world effectiveness of a parent-oriented mobile health intervention (MINISTOP 1.0 and 2.0), which have shown improvements in pre-school children's lifestyle behaviours. However, there is a need for implementation evidence. The overall aims of this study are to: (i) compare two different implementation strategies for MINISTOP 3.0 (Basic vs. Enhanced) on: acceptability, appropriateness, feasibility, organizational readiness to implement MINISTOP 3.0 within Swedish child healthcare (primary outcomes) as well as reach, costs, and adoption of MINISTOP 3.0 (secondary outcomes); (ii) evaluate cost-effectiveness of MINISTOP 3.0; (iii) explore the sustainability of MINISTOP 3.0; (iv) evaluate the determinants of effectiveness of MINISTOP 3.0 on children's key lifestyle behaviours; and (v) investigate the long-term effects of MINISTOP 3.0 on children's body mass index. METHODS: A hybrid type III implementation-effectiveness design will be used. A cluster randomized controlled trial will be conducted to compare the effects of basic versus enhanced implementation strategies on the outcomes at the child healthcare level. A minimum of 50 child healthcare centers across Sweden will participate and we aim to recruit 120 nurses. Child healthcare nurses in both groups will offer the MINISTOP 3.0 app to the families at the 2.5/3-year routine visit. Basic implementation strategies include educational meeting with nurses, formal implementation blueprint, develop/distribute educational materials and enhanced implementation includes all aforementioned strategies plus auditing/providing feedback and ongoing training for nurses. All outcomes will be assessed at baseline and 12 months post-implementation. Implementation outcomes will be assessed quantitatively using questionnaires and sustainability will be assessed qualitatively at 12 months. Children's key lifestyle behaviours will be collected through a parental questionnaire within the MINISTOP app at baseline and 6 months after they have received the app. Children's weight/height will be measured at routine visits at 2.5/3 (baseline), 4 and 5 years of age. DISCUSSION: This study will provide important implementation evidence with regards to implementing mHealth interventions within Swedish child healthcare at scale and these results have the potential to be generalized to other digital interventions being implemented in child healthcare. TRIAL REGISTRATION: ClinicalTrials.gov, NCT05667753. Registered December 29, 2022.

Associations between maternal diet, family eating habits and preschool children's dietary patterns: insights from the UPBEAT trial.

BACKGROUND: Dietary behaviours in early life often track across the life course, influencing the development of adverse health outcomes such as obesity and cardiovascular disease. This study aimed to explore the between dietary patterns (DP) in preschool children and maternal DP and family eating habits. METHODS: We conducted a secondary analysis of 488 mother-child pairs from the UK pregnancy Better Eating and Activity Trial (UPBEAT) at 3-year follow-up. Previously published DP from mothers and children (derived from food-frequency questionnaires and exploratory factor analysis) were used. Mothers' DP were "Fruits-Vegetables", "African-Caribbean", "Processed and Snacks", and children's DP were "Prudent", "Processed-Snacking", and "African-Caribbean". Family meal environments were evaluated using a 5-point Likert scale. RESULTS: Linear regression models revealed that child's prudent pattern was positively associated with maternal Fruits-Vegetables (B = 0.18 (0.08, 0.27)), Snacks patterns (B = 0.10 (0.01, 0.18)), and eating the same foods during meals (B = 0.25 (0.07, 0.43)). Child's Processed-Snacking pattern was directly associated with maternal Processed (B = 0.22 (0.13, 0.30)) and Snacks (B = 0.27 (0.18, 0.36)) patterns, receiving food as reward (B = 0.22 (0.04, 0.39)) and watching TV during meals (B = 0.27 (0.09, 0.45)). Finally, the child African-Caribbean pattern was directly associated with that from the mother (B = 0.41 (0.33, 0.50)) and watching TV during meals (B = 0.15 (0.09, 0.30)), and inversely associated with maternal processed (B=-0.09 (-0.17, -0.02)) and snacking (B=-0.08 (-0.15, -0.04)) patterns. CONCLUSIONS: Unhealthy dietary patterns in childhood are directly linked to similar maternal patterns and family meal behaviours, such as television viewing and food rewards. These findings highlight targetable behaviours for public health interventions.

Immediate and delayed effects of fantastical content on children's executive functions and mental transformation.

Watching fantastical content has been shown to negatively affect young children's executive function (EF) skills. No study has investigated how long these negative effects persist and whether they extend to other cognitive skills. The current experimental study aimed to (1) detect how long fantastical content affects children's EF performance and (2) examine whether watching fantastical content negatively affects children's other (non-EF) cognitive task performance, namely mental transformation. A total of 120 5- and 6-year-old children (M = 66 months, SD = 5.52) were randomly assigned to one of the four following conditions: (a) immediate testing after watching an 8-min non-fantastical cartoon, (b) immediate testing after watching an 8-min fantastical cartoon, (c) 10-min delayed testing after watching a fantastical cartoon, and (d) immediate testing after an 8-min free play (control condition). After exposure to each condition, children were tested on EF and mental transformation measures. Results showed that children watching a fantastical cartoon performed worse on working memory and inhibitory control tasks than children watching a non-fantastical cartoon or playing. However, the 10-min delay between the watching and testing sessions eliminated the negative impact observed on inhibitory control. Groups did not differ on cognitive flexibility and mental transformation. As in previous studies, watching fantastical content negatively affected children's EFs, but this negative impact disappeared in a few minutes and seems unique to EFs. These results suggest that fantastical content may temporarily affect attentional and information processing systems related to EFs.

How to evaluate the efficiency of rural preschool education resources and its regional differences in China.

Rural preschool education is an integral part of rural society, and improving the efficiency system of evaluation of rural preschool education resource allocation is an important strategy for the implementation of the rural revitalization. This paper uses an input-oriented three-stage DEA model to analyze the efficiency of rural preschool education resource allocation in 30 provinces in China from 2012 to 2020. The results show that external factors such as the level of urbanization, birth rate, and the scale of kindergarten impacts the efficiency of rural preschool education resource allocation significantly. Without regard to the influence of environmental and random factors, the overall trend of the average efficiency of rural preschool education resource allocation in China has improved, showing a regional pattern of "central > eastern > western." Therefore, based on the relevant policies, this paper puts forward rational suggestions for the improvement of rural preschool resource allocation efficiency in China from the perspectives of human, financial and material resources.

A longitudinal study on moral emotions and psychosocial functioning among preschool children with and without hearing loss.

Moral emotions such as shame, guilt and pride are crucial to young children's social-emotional development. Due to the restrictions caused by hearing loss in accessing the social world, deaf and hard of hearing (DHH) children may encounter extra difficulties in their development of moral emotions. However, little research so far has investigated the development trajectory of moral emotions during preschool years in DHH children. The present study used a longitudinal design to explore the development trajectories of shame, guilt, and pride, in a sample of 259 Chinese DHH and typically hearing (TH) preschoolers aged 2 to 6 years old. The results indicated that according to parent reports, DHH children manifested lower levels of guilt and pride compared to their TH peers, yet the manifested levels of shame, guilt, and pride increased throughout the preschool time at a similar pace in all children. Moreover, whilst guilt and pride contributed to increasing levels of psychosocial functioning over the preschool years, shame contributed to lower social competence and more externalizing behaviors in DHH and TH preschoolers. The outcomes imply that early interventions and adjustment to hearing loss could be useful to safeguard the social development of children with severe hearing loss, and cultural variances shall be taken into consideration when studying moral emotions in a Chinese cultural background.

The neuropsychology of early childhood and infancy.

OBJECTIVES: Piaget's theory emphasizes the biological structures children utilize to make sense of their environment and based on those experiences become able to adapt. Many factors can intervene in the gradual and complex process of development, causing an array of issues both acute and chronic. METHOD: Several studies have found that disability in the early months is a strong predictor of cognitive impairment in preschool. The presence of early functional anomalies may represent developmental delay and/or neurodevelopmental disorders. RESULTS: Understanding the risk factors and detecting such signs early on is important to prevent or minimize later cognitive, behavioral, and psychosocial problems. The study aims to emphasize how critical the early years are to a child's future cognitive, physical, emotional, and social development as well as their overall well-being. DISCUSSION: In addition, the fact that crucial developmental stages can be hampered or obstructed by a variety of factors is highlighted.

Combination effects of environmental tobacco smoke exposure and nutrients supplement during pregnancy on obesity in Chinese preschool children.

Objective: This study aimed to explore the combination effects of prenatal exposure to environment tobacco smoke (ETS) and nutrients supplement during pregnancy on childhood obesity in preschoolers. Methods: A cross-sectional study was conducted with 58,814 child-mother dyads from 235 kindergartens in Longhua District of Shenzhen, China in 2021. A self-administered structured questionnaire was completed by mothers to collect socio-demographic characteristics, prenatal ETS exposure, and nutrients supplement in pregnancy, and preschoolers' heights and weights were measured at the same time. After controlling for potential confounding variables, logistic regression models and cross-analyses were used to examine the independent and combination effects of maternal prenatal ETS exposure and nutrients supplementation during pregnancy on obesity in preschool children. Results: The results of our study showed that prenatal ETS exposure increased the risk of childhood obesity (AOR = 1.22, 95% CI = 1.11-1.34) in preschoolers. In addition, risk of childhood obesity was significantly higher when mothers didn't take supplements of multivitamins (AOR = 1.12, 95% CI = 1.05-1.20), folic acid (AOR = 1.23, 95% CI = 1.10-1.37) and iron (AOR = 1.11, 95% CI = 1.04-1.19) during pregnancy. The cross-over analysis showed that the combination of prenatal ETS exposure with mothers taking no multivitamins (AOR = 1.40, 95% CI = 1.21-1.62), no folic acid (AOR = 1.55, 95% CI = 1.12-2.14) and no iron (AOR = 1.38, 95% CI = 1.19-1.59) during pregnancy also increased the risk of obesity among Chinese preschoolers. We also discovered additive interactive effects between prenatal ETS exposure and no maternal multivitamin, folic acid and iron supplementation in pregnancy on the risk of obesity in preschoolers. Conclusion: The combination of prenatal exposure to ETS with no supplementation of these nutrients might jointly increase the risk of childhood obesity. Public health interventions are needed to reduce prenatal exposure to ETS and to encourage mothers to take appropriate multivitamin, folic acid and iron supplements during pregnancy.

Prospective Association Between 24-Hour Movement Behaviors and Fundamental Movement Skills in Chinese Preschoolers During the COVID-19 Pandemic: A Compositional and Reallocation Analysis.

BACKGROUND: This prospective observation study explored the association between 24-hour movement behaviors and fundamental movement skills (FMS) in Chinese preschoolers during the COVID-19 pandemic. METHODS: Four hundred and eighteen preschoolers (226 males; 4.0 [0.6] y old) from Zhuhai, China, completed the device-based physical activity (PA) and sedentary behavior measures, and sleep duration was reported by parents at baseline (October 2021 to December 2021). FMS was assessed using the Test of Gross Motor Development: Third Edition at 1-year follow-up (October 2022 to December 2022). The compositional analysis and isotemporal substitution were used. RESULTS: Moderate to vigorous PA (MVPA) was positively associated with locomotor skills and ball skills (P < .05), and light physical activity was negatively associated with locomotor skills (P < .05) during the COVID-19 pandemic. FMS improvements were linked to the addition of MVPA at the expense of light physical activity, sedentary behavior, and sleep. The estimated detriments to FMS were larger in magnitude than the estimated benefits of time reallocation from MVPA to light physical activity, sedentary behavior, and sleep. CONCLUSIONS: This study provides evidence about 24-hour movement behaviors and FMS during the COVID-19 pandemic and highlights the importance of participating in MVPA to improve preschoolers' FMS development during the COVID-19 era.

Interpretable machine learning for allergic rhinitis prediction among preschool children in Urumqi, China.

This study aimed to investigate the advantages and applications of machine learning models in predicting the risk of allergic rhinitis (AR) in children aged 2-8, compared to traditional logistic regression. The study analyzed questionnaire data from 7131 children aged 2-8, which was randomly divided into training, validation, and testing sets in a ratio of 55:15:30, repeated 100 times. Predictor variables included parental allergy, medical history during the child's first year (cfy), and early life environmental factors. The time of first onset of AR was restricted to after the age of 1 year to establish a clear temporal relationship between the predictor variables and the outcome. Feature engineering utilized the chi-square test and the Boruta algorithm, refining the dataset for analysis. The construction utilized Logistic Regression (LR), Support Vector Machine (SVM), Random Forest (RF), and Extreme Gradient Boosting Tree (XGBoost) as the models. Model performance was evaluated using the area under the receiver operating characteristic curve (AUROC), and the optimal decision threshold was determined by weighing multiple metrics on the validation sets and reporting results on the testing set. Additionally, the strengths and limitations of the different models were comprehensively analyzed by stratifying gender, mode of birth, and age subgroups, as well as by varying the number of predictor variables. Furthermore, methods such as Shapley additive explanations (SHAP) and purity of node partition in Random Forest were employed to assess feature importance, along with exploring model stability through alterations in the number of features. In this study, 7131 children aged 2-8 were analyzed, with 524 (7.35%) diagnosed with AR, with an onset age ranging from 2 to 8 years. Optimal parameters were refined using the validation set, and a rigorous process of 100 random divisions and repeated training ensured robust evaluation of the models on the testing set. The model construction involved incorporating fourteen variables, including the history of allergy-related diseases during the child's first year, familial genetic factors, and early-life indoor environmental factors. The performance of LR, SVM, RF, and XGBoost on the unstratified data test set was 0.715 (standard deviation = 0.023), 0.723 (0.022), 0.747 (0.015), and 0.733 (0.019), respectively; the performance of each model was stable on the stratified data, and the RF performance was significantly better than that of LR (paired samples t-test: p < 0.001). Different techniques for evaluating the importance of features showed that the top5 variables were father or mother with AR, having older siblings, history of food allergy and father's educational level. Utilizing strategies like stratification and adjusting the number of features, this study constructed a random forest model that outperforms traditional logistic regression. Specifically designed to detect the occurrence of allergic rhinitis (AR) in children aged 2-8, the model incorporates parental allergic history and early life environmental factors. The selection of the optimal cut-off value was determined through a comprehensive evaluation strategy. Additionally, we identified the top 5 crucial features that greatly influence the model's performance. This study serves as a valuable reference for implementing machine learning-based AR prediction in pediatric populations.

Shaping Student Relationships: The Role of Personality in Early Childhood Pre-Service Teachers.

The purpose of this explanatory sequential mixed-methods study is to explain teacher-student relationships in preschool classrooms in terms of the child's temperament and the pre-service preschool teachers' personalities. The study was conducted using a sequential exploratory mixed-methods design. Since both quantitative and qualitative data were obtained, sampling was carried out in two stages: quantitative random stratified sampling, and qualitative purposive sampling. Quantitative data were obtained from 126 pre-service teachers. The qualitative study group consisted of 18 pre-service teachers. Quantitative data were collected using the Student-Teacher Relationship Scale-Short Form, the Short Temperament Scale for Children (STSC), and the Five Factor Personality Inventory (FPI). Qualitative data were obtained from interviews with 18 teachers. The findings revealed that the student-teacher relationship can be explained by adult and child characteristics. In addition, pre-service teachers' perceptions of the student-teacher relationship are explained by adult characteristics much more than pre-service teachers' perceptions.

Development of Spanish Nutrition Screening Tool for Hispanic Preschoolers.

Nutrition screening tools may facilitate early nutrition interventions specifically with Hispanic populations that are already at higher risk. There is a paucity of culturally competent and validated nutrition screening tools for 3-5-year-old Hispanic children. The purpose of this study was to develop a Spanish nutrition screening tool for 3-5-year-old children to be used by Spanish-speaking parents in community settings to appropriately address malnutrition risk factors with cultural sensitivity. All phases of the study were conducted in Spanish with native Spanish speakers. Face and content validity were established using focus groups, expert reviews, and pilot testing of the tool with Spanish-speaking parents. Parents of children 3-5 years old whose primary language was Spanish (n = 39) completed the nutrition screening, and a nutritionist completed an in-depth nutrition assessment of these children. Criterion validity was measured by comparing the results of the nutrition screening tool with the in-depth nutrition assessment. The nutrition screening tool had a sensitivity of 91.67% and a specificity of 81.48%. The negative predictive value was 69%, and the positive predictive value was 96%. The nutrition screening tool may be used to identify malnutrition in Hispanic children and needs further validation in larger samples.

[Current Situation and Influencing Factors of Kindergarten Teachers' Participation in Training for Preschool Sex Education].

Objective To understand the current situation and influencing factors of kindergarten teachers' participation in training for preschool sex education in Luzhou city,and provide a basis for improving the sex education literacy of kindergarten teachers in the future. Methods A multi-stage stratified cluster sampling method was adopted,and a questionnaire survey was conducted from December 2021 to January 2022 on the knowledge,attitude,and practice of preschool sex education among all the teachers in 24 kindergartens in Luzhou city. Results Among the 461 teachers,43.0% had participated in lectures/courses/training activities related to preschool sex education;99.1% hoped to participate in lectures/courses/training activities related to preschool sex education;82.6% learned about child sexual knowledge through school education;75.5% expressed the hope to learn about child sexual knowledge through expert training.The results of multivariate Logistic regression showed that except private kindergartens as an inhibiting factor (OR=0.57,95%CI=0.37-0.87,P=0.008),high monthly income (OR=3.52,95%CI=1.13-9.30,P=0.011),more ways to know about sex education knowledge (OR=2.87,95%CI=1.76-4.70,P<0.001),and social support (OR=1.58,95%CI=1.04-2.38, P=0.030) were promoting factors for teachers to participate in the training for preschool sex education. Conclusion The kindergarten teachers presented a participation rate but a high demand for the training for preschool sex education.They mainly obtain the sex education knowledge from school education.The nature of kindergarten,monthly income of teachers,social support situation,and ways of understanding sex education knowledge are the key factors influencing the teachers' participation in the training for preschool sex education.

Behavioral characteristics of toddlers later identified with an autism diagnosis, ADHD symptoms, or combined autism and ADHD symptoms.

BACKGROUND: Autism commonly co-occurs with attention-deficit/hyperactivity disorder (ADHD), but less is known regarding how ADHD symptoms impact the early presentation of autism. This study examined early behavioral characteristics of a community sample of toddlers later identified with autism diagnosis, ADHD symptoms, combined autism and ADHD symptoms, or neither condition. METHODS: Participants were 506 toddlers who were part of a longitudinal study of children's behavioral development. Parents completed questionnaires about their children's behavior at two time points. Four groups were identified based on study measures or medical record: autism diagnosis (n = 45), elevated ADHD symptoms (n = 70), autism and ADHD symptoms (n = 30), or neurotypical development (n = 361). Relationships between early parent report of autism- and ADHD-related behaviors, social-emotional and behavioral functioning, and caregiver experience and subsequent group designation were evaluated with adjusted linear regression models controlling for sex. RESULTS: Significant group differences were found in measures of autism-related behaviors, ADHD-related behaviors, externalizing and internalizing behaviors, and parent support needs (p < .0001). Pairwise comparisons indicated toddlers later identified with combined autism diagnosis and ADHD symptoms had higher levels of autism-related behaviors, externalizing and internalizing behaviors, and autism-related parent support needs compared to the other groups. Toddlers with subsequent elevated ADHD symptoms or combined autism diagnosis and ADHD symptoms exhibited similar levels of ADHD-related behaviors, while both groups displayed more ADHD-related behaviors than toddlers subsequently identified with autism or those with neither condition. CONCLUSIONS: In this community sample, toddlers for whom combined autism diagnosis and ADHD symptoms were subsequently identified showed a distinct presentation characterized by higher early autism-related behaviors, broader behavioral concerns, and higher parent support needs. Presence of ADHD symptoms (alone or in combination with autism) was associated with higher parent-reported ADHD-related behaviors during toddlerhood. Results indicate that ADHD-related behaviors are manifest by toddlerhood, supporting screening for both autism and ADHD during early childhood.

Comparison of executive functions in Russian and Japanese preschoolers.

This study analyzed differences in level of main executive function (EF) components (such as inhibition, working memory, and cognitive flexibility) among Russian and Japanese preschoolers. The study involved 102 children of 5-6.9 years old: 51 child from Russia and 51 child from Japan. Out of 102 children 48 were boys and 54 girls. It was found that the cognitive flexibility level in Russian children is higher and inhibition level is lower than in Japanese children. The results of the boys' EF comparison showed that boys from Russia have lower cognitive and physical inhibition levels than boys from Japan. Also it was shown that cognitive flexibility in Russian girls is significantly higher and cognitive inhibition is lower than in Japanese girls. The results obtained are discussed from the point of view of possible cultural differences in the two countries studied, which are manifested in the expectations of adults from children.

Associations between adherence to 24-hour movement guidelines and socio-emotional competence among preschool children: A cross-sectional study.

BACKGROUND: This study investigated the association between adherence to 24-h movement guidelines and socioemotional competence among Chinese preschool children. METHODS: A total of 1288 parents of Chinese preschoolers (54.64 % boys, 45.36 % girls; Mage = 4.48, SD = 0.97) reported the time their children spent on physical activity (PA), screen time (ST), and sleep duration (SD), and completed questionnaires measuring socioemotional competence. Multiple logistic regression analyses were used to explore the associations between individual and combined measures of PA, ST, and SD, and the risk of low socioemotional competence. RESULTS: The risk of low socioemotional competence was significantly lower for children aged 4 (odds ratio [OR] = 0.47, 95 % CI: 0.31-0.71), 5 (OR = 0.23, 95 % CI: 0.15-0.35), and 6 (OR = 0.16, 95 % CI: 0.10-0.25) compared to 3-year-olds. Children with a family income level higher than 20,000CNY had a significantly lower risk of low socioemotional competence than those with a family income level not higher than 3000CNY (OR = 0.21, 95 % CI: 0.08-0.59). Urban residency was associated with significantly lower odds of low socioemotional competence than rural residency (OR = 0.41, 95 % CI: 0.21-0.82). Adherence to the PA-only guidelines (OR = 0.45, 95 % CI: 0.22-0.94), SD-only guidelines (OR = 0.25, 95 % CI: 0.08-0.72), ST + SD guidelines (OR = 0.33, 95 % CI: 0.16-0.67), and PA + ST + SD guidelines (OR = 0.36, 95 % CI: 0.18-0.70) were associated with a lower risk of low socioemotional competence. In addition, among boys, only adherence to the PA + ST + SD guidelines (OR = 0.36, 95 % CI: 0.14-0.90) was associated with a lower risk of low socioemotional competence. Among girls, adherence to SD guidelines only (OR = 0.22, 95 % CI: 0.04-0.90), ST + SD guidelines (OR = 0.17, 95 % CI: 0.06-0.49), and PA + ST + SD guidelines (OR = 0.37, 95 % CI: 0.14-0.91) were all associated with a lower risk of low socioemotional competence. CONCLUSIONS: Adhering to 24-h movement guidelines is crucial for enhancing socioemotional competence in preschool children, especially girls. Interventions should focus on promoting physical activity, reducing screen time, and ensuring adequate sleep.
