The real-world effectiveness of preschoolers wearing masks on campus to prevent respiratory infectious diseases: a cohort study.

Background: Respiratory infections are common in the pediatric population. Preschoolers, especially those in kindergarten and 3-6 years old, are highly vulnerable to various respiratory infections. Objective: To investigate the efficacy of indoor mask-wearing in mitigating respiratory infections in preschoolers in a real-world campus setting. Methods: The study was conducted over a 115-day period in a kindergarten. Eligible children were assigned into study and control groups. The study group wore masks indoors but not outdoors, and the control group did not wear masks in either setting. We used a questionnaire to collect participant information, including age, height, weight, monthly dietary living expenses, family annual income, parent education level, primary caregiver, number of family members, and number of children under 6 years of age in the household. Incidences of clinical respiratory infections were recorded. We calculated the relative risk and analyzed the relationship between mask-wearing and respiratory infections by inter-group comparison, logistic regression, and Cox regression analyses. Results: A total of 135 preschoolers were included, with 35 and 100 preschoolers in the study and control groups, respectively. Baseline comparisons showed a significant difference in the number of children under 6 years old in the household between the two groups. Mask-wearing did not significantly reduce the risk of respiratory infections (RR = 1.086, 95% CI: 0.713, 1.435). Logistic and Cox regression analyses also showed no significant relationship between mask-wearing and occurrence of respiratory infections after controlling for potential confounders (OR = 0.816, 95% CI: 0.364, 1.826, and HR = 0.845, 95% CI: 0.495, 1.444). Conclusion: Indoor mask-wearing did not reduce the incidence of respiratory infections in preschoolers in a real-world campus setting. However, this study included a small number of preschoolers and observed them for a short period of time. Preschoolers were instructed to wear masks only when indoors. These factors could lead to bias and limit the generalizability of the study results.

Maternal Phubbing and Problematic Media Use in Preschoolers: The Independent and Interactive Moderating Role of Children's Negative Affectivity and Effortful Control.

Purpose: Given that mother plays the main nurturing role in a family unit and their unique influence on children's development, the current study aimed to examine the influence of maternal phubbing on children's problematic media use and the independent and interactive moderating role of children's negative affectivity and effortful control. Methods: Participants were 1986 children aged 3 to 6 years in Shanghai, China. Their mothers were asked to complete a series of questionnaires including parental phubbing scale, problematic media use measure, and child behavior questionnaire. To investigate the moderating influence of children's negative affectivity and effortful control, hierarchical linear regression analyses were conducted using SPSS 24.0. Simple slopes analyses and the Johnson-Neyman technique were further used to depict moderation effects. Results: Maternal phubbing was associated with higher levels of problematic media use in preschool children (ß = 0.18, p <.001, [0.14, 0.22]). Children's negative affectivity acts as a risk factor, exacerbating the adverse effects of maternal phubbing on children's problematic media use (ß = 0.05, t = 2.69, p < 0.05), whereas children's effortful control acts as a protective factor, buffering the link between maternal phubbing and children's problematic media use (ß = -0.10, t = -5.00, p < 0.001). Conclusion: These results suggest that interventions seeking to promote appropriate digital development in preschoolers should take the child's temperament into account and be complemented by active parental mediation and involvement.

Development of EEG Response to Unpleasant, Pleasant, and Neutral Tactile Stimuli.

BACKGROUND: The study of tactile perception during a childhood is extremely important for understanding the social and communicative aspects of the child's development. Tactile perception of stimuli with different valence can have different normative stages of development. METHODS: In the present study, we examined changes in linear and nonlinear electroencephalogram (EEG) parameters during the presentation of pleasant (C-tactile optimal stroking), unpleasant (ice stroking), and neutral tactile stimuli in three groups of healthy volunteers: preschoolers 4 and 5 years, school-age children from 8 to 10 years, and adults from 20 to 40 years. RESULTS: According to our findings, child maturation plays a significant role in the perception of pleasant and neutral tactile stimuli. Patterns of EEG dynamics related to tactile perception showed greater similarity between adult volunteers and school-aged children than preschoolers. CONCLUSIONS: Non-linear EEG parameters such as fractal dimension (FD), envelope mean frequency (EMF), and power spectral density (PSD) dynamics of the theta-rhythm were particularly sensitive to developmental changes in tactile perception. Hjorth complexity and peak alpha frequency (PAF) scores may serve as indicators of mature perception of С-tactile (CT)-stimuli.

Prospective Associations of Maternal Depressive Symptoms and Emotion Dysregulation with Children's Internalizing Problems: The Moderating Role of Fathers.

Parents, including fathers, contribute to the early development of internalizing symptoms, which is observable and prevalent among young children. This longitudinal study examined the moderating role of paternal depressive symptoms/emotion dysregulation in the prospective associations between maternal depressive symptoms/emotion dysregulation and children's internalizing problems (depressive and anxiety symptoms). Ninety-four preschoolers and their mothers and fathers participated. Parents completed online questionnaires when their children were four years old and one year later. Results indicated that higher paternal depressive symptoms were associated with an increase, while lower paternal symptoms were associated with a decrease, in the negative impact of maternal emotion dysregulation on children's later depressive, but not anxiety, symptoms. We also tested the moderating role of paternal emotion dysregulation, these pathways were not significant. The findings enhance our understanding of the interaction between maternal and paternal psychological characteristics in contributing to children's anxiety and depressive symptoms.

Association between parental well-being and preschooler stress measured as hair cortisol concentration: A prospective cohort study.

Hair cortisol concentration (HCC) is a valuable biomarker for evaluating chronic stress in preschoolers. However, few studies have explored early life HCC and its associated factors. This prospective cohort study analysed the HCC in children aged 6-48 months and its associations with parental HCC as well as positive and negative parental mental health outcomes. We used data from the ongoing Longitudinal Examination Across Prenatal and Postpartum Health in Taiwan (LEAPP-HIT) project, conducted in Taipei between 2020 and 2024. Hair samples were collected from both parents and children in 177 families (91 samples obtained during pregnancy and 86 during the postpartum period). The parents also completed self-reported questionnaires. Multiple linear regression was conducted to analyse the data. We observed a significant positive correlation between parents' and preschoolers' HCC. Furthermore, maternal depression (adjusted beta coefficient [aß] = 0.09, 95% confidence interval [CI] = 0.02, 0.16) and perceived stress (aß = 0.15, 95% CI = 0.02, 0.26) were positively associated with preschoolers' HCC. By contrast, higher maternal eudaimonia was associated with lower HCC in preschoolers (aß = -0.11, 95% CI = -0.20, -0.01). For parents, maternal depression, anxiety, and perceived stress were independently associated with an increased HCC during the postnatal period, whereas maternal eudaimonia was negatively associated with HCC. Our results indicate that both mothers and fathers affect children's responses to stress. Assessment of cortisol stress hormone concentrations through hair samples can be a key means of detecting preschoolers' stress levels and enabling early intervention.

On the psychological effects of child-like space design on preschoolers under anesthesia: A qualitative study.

Background and Aims: In this study, a pediatric hospital was selected as the study setting, to investigate the effects of the environment of a pediatric operating room child-friendly space on preschool children under anesthesia. Methods: Interviews were conducted in pediatric hospitals through anesthesia of preschool children. This study randomizing children between the ages of 1 and 7 years (seven males, five females, mean age 3.8 years, standard deviation 0.7). Twelve participants took part in this interview, which was an in-depth interview of preschoolers' perceptions of anesthesia using generalized data analysis to assess young children's perceived preferences and sensitivity to the environment. Preschoolers' preferences for feeling under anesthesia are reflected in four main areas. Results: (1) Interesting and engaging environment. (2) Humanized design, free of fear and unfamiliarity. (3) Caring, patient, and compassionate care by healthcare professionals. (4) High cooperation of the child and good doctor-patient relationship. Conclusion: The key findings of this study may help designers and clinicians to design a toddler-friendly built environment where pediatric hospital child-friendly spaces are designed to benefit their health and maximize their cooperation and psychological recovery.

Socioeconomic Status and Rate of Poverty in Overweight and Obesity among Spanish Children and Adolescents.

BACKGROUND: This study aimed to analyze the relationship between socioeconomic status (SES), poverty rate, and the prevalence of overweight/obesity or obesity in children and adolescents aged 2-14. METHODS: Parents or guardians reported the weight and height of participants, used to calculate body mass index (BMI) and BMI z-scores according to the International Obesity Task Force standards. Participants were categorized into "overweight/obesity" and "no overweight/obesity" and further into "obesity" and "no obesity". The rate of poverty rate was determined using data from the National Statistics Institute of Spain, defining it as the percentage of people with income below 60% of the national median. SES was based on the head of household's occupation and categorized into low, medium, and high levels. RESULTS: Adjusted multilevel models showed participants with medium or high SES had lower odds of overweight/obesity compared to those with low SES (medium SES: odds ratio [OR]: 0.63, 95% confidence interval [CI]: 0.54-0.73; high SES: OR: 0.59, 95% CI: 0.49-0.70). Participants in the high-poverty group had higher odds of having overweight/obesity (OR: 1.40, 95% CI: 1.13-1.74) compared to the low-poverty group. CONCLUSIONS: The study highlights significant socioeconomic disparities in childhood overweight/obesity, emphasizing the potential impact of SES and poverty on health outcomes in Spanish children and adolescents.

Preschool children's physical activity in the home, childcare and neighbourhood environment: A latent profile analysis using device-based measures.

Based on the socioecological conceptual model, the physical environment within the home, childcare and neighbourhood domains are key factors that influence preschool children's physical activity; however, the relative importance of each of these domains for preschool children's physical activity is unclear. We explored the physical environment characteristics within three latent profiles of 115 preschool children aged 2-5 years based on where they accumulated moderate-to-vigorous physical activity (MVPA) across five GPS-derived environmental domains. The three profiles were "Active at home" (n = 41), "Active except close to home" (n = 61), and "Active except in local neighbourhood" (n = 13). Compared to other profiles, "Active at home" had fewer parks and playgrounds within their 500-1600 m neighbourhood. Findings suggest preschool children's MVPA profiles are reflections of their physical environmental opportunities.

Nature and success: Outdoor play is linked to school readiness.

BACKGROUND: and Purpose: Outdoor play is widely acknowledged for its benefits to physical health and psychological well-being, yet its relationship with school readiness remains understudied in preschoolers. To address this gap in the literature, this study investigated how outdoor play relates to cognitive and psychosocial development among a nationally representative sample of preschoolers. MATERIALS AND METHOD: Data on the duration of outdoor play (on weekdays and weekends) and specific cognitive and psychosocial outcome variables (i.e., early learning skills, self-regulation, social-emotional development, and flourishing) were collected via questionnaires provided to the caregivers of preschoolers. Logistic regressions were performed to examine the associations between outdoor play with cognitive and psychosocial outcomes while adjusting for covariates and calculate the odds ratio with 95 % confidence intervals (CI). RESULTS: Among the 10,682 preschoolers (i.e., 3-5y) included in this study (i.e., 5558 boys, Mage = 3.98 ± 0.99 years), there was a lower percentage of preschoolers engaged in outdoor play for over 3 h per day on weekdays (33.39 %) compared to weekends (56.85 %). Outdoor play in preschoolers is positively associated with various domains of school readiness, and engaging in outdoor play for more than 3 h per day is associated with more beneficial outcomes. CONCLUSION: The findings of this cross-sectional study suggest that promoting outdoor play among preschoolers can be an effective strategy for enhancing cognitive, social, and emotional development in this age group although further intervention studies are required to buttress this assumption empirically.

An isochronic substitution benefit study of the effects of screen time on the cognitive abilities of 3-6 children.

Purpose: To investigate the impact of substituting screen time with other activities on children's cognitive ability. Method: A total of 583 children (299 males and 284 females), aged 3-6 years, were selected as participants. Correlation, regression, and isochronic substitution analyses were used. Results: Screen entertainment time on TV (SET_TV) was negatively associated with children's math ability. However, screen learning time on other electronic devices besides TV (SLT_OED) and non-screen learning time by learning alone (NSLT_LA) were positively associated with math ability and language ability. After controlling for gender, age, and family socio-economic status, SET_TV remained negatively associated with math ability, while NSLT_LA remained positively correlated. Furthermore, substituting 10 min of SET_TV with NSLT_LA resulted in an increase of 0.55 in language ability and 0.87 in math ability. Similarly, substituting SLT_OED, sleeping at home, and exercising outside of kindergarten for 10 min of SET_TV resulted in an increase of 0.90, 0.43, and 0.61 in math ability, respectively. Conclusions: There are cognitive benefits when screen recreation time is replaced with screen learning time, non-screen learning time, sleep time, and exercise time, with the highest benefits observed when screen recreation time is substituted with NSLT_LA.

Promoting theory of mind and emotion understanding in preschool settings: an exploratory training study.

Introduction: This new exploratory study is part of a larger ongoing follow-up project. Its specific aim was to verify whether an innovative European Program, primarily designed to enhance children's social and emotional learning, led to gains in theory of mind and emotion understanding when implemented in preschool settings. Methods: Thirty-four children (mean age: 56.4 months; SD: 10.1; range: 40-70 months) participated in the study. They were randomly and equally divided into a training group and a control group. The training sample completed eight linguistic-conversational activities drawn from the Program, in groups of 5 to 6 children, over 8 weeks. The activities were based on listening to stories and/or watching videos and then thinking and talking about the inner world (thoughts and emotions) of the story characters as well as the participants' own inner states. During the training phase, the children in the control group engaged in drawing or free play activities. At both the pre-test and post-test phases of the study, all the children completed a language test, a battery of theory of mind (ToM) tasks (including 'change of location' and 'unexpected content' tasks), and the Test of Emotion Comprehension which evaluates nine components of emotion understanding (EU). The validated national versions of the tests were administered in all cases. Results: Significant differences were identified between the training and control groups. Indeed, the participants in the Program training activities, which were based on conversational exchanges between an adult and a group of children, as well as among the children themselves, outperformed the control participants on both overall theory of mind and overall emotion understanding. A more detailed analysis showed that the training group outperformed the control group in relation to both specific components of EU and the 'change of location' ToM task. Discussion: The results of this exploratory study suggest that the Program is effective at enhancing preschoolers' social understanding and thus merits implementation in preschool settings.

A study on the development of happiness scale for Chinese young children.

This study was conducted to develop an assessment tool for measuring happiness among Chinese preschoolers, and to verify the reliability and validity of this tool. A total of 269 preschoolers aged 3 to 5 years from kindergartens and childcare centers in Hangzhou, China, were surveyed. The Preschooler Happiness Scale, constructed through literature review and interviews with preschoolers, underwent expert content validity verification and pilot testing to refine items. The validity and reliability of the scale were verified in this study, resulting in the development of the final Preschooler Happiness Scale comprising 6 sub-factors and 25 items. The reliability verification revealed a high overall reliability of 0.91 for the Preschooler Happiness Scale, confirming its trustworthiness as a tool. The academic significance of the findings and the practical utility of the Preschooler Happiness Scale in early childhood education settings in China were discussed based on the results of this study.

Study on the relationship and related factors between physical fitness and health behavior of preschool children in southwest China.

OBJECTIVE: To investigate the physical fitness level and health behavior status of preschool children in China, explore the relationship between physical fitness and health behavior, and further reveal the main factors affecting health behavior, to provide a reference for improving the physical fitness level of preschool children and maintaining healthy behavior. METHODS: A total of 755 preschool children (394 boys and 361 girls, aged 4.52 ± 1.11 years) were selected from Chongqing and Liupanshui in China by cluster random sampling method for questionnaire survey and physical monitoring, and SPSS21.0 software was used to process and analyze the data. RESULTS: (1) Heart rate (p = 0.015), protein content (p < 0.001), and time spent on the balance beam (p < 0.001) were significantly lower in boys than in girls, while BMI (p = 0.012), muscle mass (p < 0.001), and distance of standing long jump (p < 0.001) were significantly higher in boys than in girls. Meanwhile, systolic blood pressure (p = 0.004) and diastolic blood pressure (p = 0.001) of rural children were significantly higher than those of urban children, while BMI (p < 0.001) and sitting forward flexion (p = 0.019) were significantly lower than those of urban children. (2) The light-intensity physical activity (LPA) and moderate to vigorous physical activity (MVPA) of boys were significantly higher than that of girls (p < 0.001), and the MVPA of urban children was significantly higher than that of rural children (p = 0.001), and the former participated in sports classes more frequently (p < 0.001). (3) There was a significant correlation between physical activity (PA) and physical fitness indicators of preschoolers. Participating in sports interest classes was only significantly correlated with systolic blood pressure (r = 0.08) and sitting forward flexion (r = 0.09). (4) The PA level of preschool children was related to gender, household registration, kindergarten nature, age, residence environment, parental support, and participation degree. Participation in sports interest classes was related to gender, the nature of the kindergarten, household registration, age, and parent participation. Daily screen time was related to household registration, the nature of the kindergarten, the environment of residence, and the value perception of parents. CONCLUSIONS: There were different degrees of correlation between preschool children's physical fitness and health behaviors, and children's health behaviors were closely related to gender, environment, parents, and other factors. Therefore, how to increase the protective factors of children's health behaviors and controlling the risk factors may be crucial to promoting the development of good health behaviors and improving the physical fitness of preschool children.

Social-emotional problems in 3-to 5-year-old children: a cross-sectional study of highly educated migrants in a Chinese urban area.

Background: Previous research has primarily examined the mental well-being of children from labor migrant families, yet there is a lack of understanding regarding the mental well-being of children from highly educated migrant backgrounds. This study investigated the social-emotional problems of 3-5-year-olds from highly educated migrant families residing in an urban area of China, as well as explored potential differences in demographic variables. Methods: A cross-sectional study was conducted in Qiantang District, Hangzhou, China, with 1,494 (53.3% boys) children selected via a convenient sampling method. The Ages & Stages Questionnaires: social-Emotional, Second Edition (ASQ:SE-2) was used to measure social-emotional problems. Results: The results showed that 23.6% of the children were at risk for social-emotional problems. More boys (26.7%) than girls (20.1%) had scores above the cut-off. Additionally, more children in the low socioeconomic status (29.9%) had scores above the cut-off than those in the high socioeconomic status (18.9%). There were three common issues among all age groups: "being more active than others," "excessive attachment to parents," and "being overly friendly with strangers. Conclusion: The social-emotional development of children from highly educated migrant families is a significant aspect that deserves recognition, contributing valuable insights to the existing literature on this topic.

Evaluation of the Centers for Disease Control and Prevention's Essentials for Parenting Toddlers and Preschoolers on parent behavioral outcomes.

BACKGROUND: The Centers for Disease Control and Prevention's web-based behavioral parent training (BPT) program, Essentials for Parenting Toddlers and Preschoolers (EfP), uses a psychoeducational approach to promote positive parenting and address common parenting challenges. The purpose of this study was to assess the effects of EfP on parenting behavior and whether implementation format impacted behavioral outcomes. METHODS: A sample of 200 parents of 2- to 4-year-old children were recruited via Internet advertising. Using a repeated single subject, multiple baseline design, parents were randomly assigned to guided navigation (GN; n = 100) or unguided navigation (UN; n = 100) study conditions. Parents were provided secure access to the EfP website and completed 18 weekly surveys. Latent growth curve modeling was used to determine intervention effectiveness on behavioral outcomes. RESULTS: Latent growth curve modeling indicated both GN and UN study conditions significantly increased use of praise (ß = 0.19, p = 0.038) and commands and consequences (ß = 0.17, p < 0.001), and decreased corporal punishment use (ß = -0.01, p = 0.017) and attitudes promoting corporal punishment (ß = -0.01, p < 0.001) over the study period. The UN condition exhibited a significant initial decrease in time-out use that increased over time to match the GN condition. CONCLUSIONS: This study provides evidence for the effectiveness of EfP in promoting non-violent parenting behavior and increasing positive parenting techniques. The format of EfP implementation made no difference in parenting behaviors over time. Digital BPT programs like EfP provide access to evidence-informed parenting resources and can enhance positive parenting.

Dietary patterns and risk of developing asthma among pre-schoolers.

BACKGROUND: Early childhood dietary patterns have been identified as potential factors that can influence the development of asthma in children. The objective of the study was to determine the association between dietary patterns, identified through principal component analysis (PCA), and asthma in pre-schoolers. METHODS: This unmatched case-control study used data from 3145 pre-schoolers participating in the parent population-based observational study conducted in a District Municipality, Province. The study consisted of 189 pre-schoolers (63 with asthma, 126 controls) between 1 and 8 years. We identified primary dietary patterns by conducting a PCA on reported food consumption data from the Quantitative Food Frequency Questionnaire (QFFQ). Multivariate logistic regression models determined the relationship between food patterns and asthma. RESULTS: The results of our study identified four primary dietary patterns that defined the dietary preferences of the pre-schoolers: Meat general and dressings pattern, Healthy dietary pattern, Sugary and/or sweetened drinks pattern, and Mixed dietary pattern. The consumption of sugary and sweetened drinks (adjusted OR 7.0, 95% CI: 2.3-21.1-1; p = 0.00) as well as a Mixed dietary pattern (adjusted OR 4.0, 95% CI: 1.4-11.1; p = 0.03) were positively associated with a higher probability of developing asthma. A Healthy dietary pattern (adjusted OR 0.02, 95% CI: 0.00-0.09; p = 0.00) was negatively associated with an increased likelihood of presenting with asthma. CONCLUSIONS: In the current study, a Healthy dietary pattern was negatively associated with an increased likelihood of presenting with asthma. Diet modification may be a potential intervention to impact the increasing prevalence of this disease.

Development of number line estsimation in Chinese preschoolers: a comparison between numerical and non-numerical symbols.

To examine the level of number line estimation (NLE) in Chinese children with respect to representations of both numerical (Arabic numerals) and non-numerical symbols (dots), a total of 192 Chinese preschoolers aged between 4 and 5 years participated in four different NLE tasks. These tasks were paired to evaluate the accuracy and patterns of children's estimations in both numerical and non-numerical symbol contexts. Our findings indicate that, for Chinese preschoolers, relatively precise numerical symbol representations begin to emerge as early as 4 years of age. The accuracy of number line estimates for both 4- and 5-year-old children gradually increases in tasks involving both numerical and non-numerical symbols. Additionally, the development and patterns observed in the number line estimates of 4- and 5-year-old Chinese preschoolers are similar in both numerical symbol and non-numerical symbol tasks. These results indicate that the initiation of relatively precise numerical symbol representation and the turning point in the developmental trajectory, where the relatively precise representation for numerical symbols surpasses that of non-numerical ones, occur earlier in Chinese children than in their Western counterparts.

Unfavorable food consumption in children up to school entry age: results from the nationwide German KiESEL study.

Introduction: Evidence points toward the early life being crucial for preventing nutrition-related diseases. As promotion of healthier food preferences in toddlerhood and preschool age might still modulate the trajectories of disease risk, understanding diet in these age groups is necessary. The objective was to analyze food consumption and diet quality of 1-5-year-old children living in Germany in relation to age and sex. Methods: Data from 890 children, a subsample of the representative, cross-sectional Children's Nutrition Survey to Record Food Consumption (KiESEL) conducted by the German Federal Institute for Risk Assessment in 2014-2017, were analyzed. Dietary data were collected using food records (3 consecutive plus 1 independent day). Diet quality was evaluated against the German food-based dietary guidelines (FBDG). Results: Consumption of unfavorable foods (e.g., sweets, soft drinks) exceeded the recommended maximum of 10% of energy intake (E%) by a multiple in all age and sex groups (medians: 24.8-35.8 E%). Preschoolers consumed more unfavorable foods than toddlers and boys more than girls. More than half of the children exceeded the recommendation for meat intake (medians: 2.3-3.2% of the total food consumption (%TFC) vs. 2 %TFC), especially preschoolers. In nearly all children, vegetable consumption was too low (medians: 4.2-4.5 %TFC vs. 12 %TFC). Also, milk/milk product consumption was below recommendations, more so in preschoolers (median: 12.0 %TFC ♂, 11.9 %TFC ♀ vs. 18 %TFC) than in toddlers (median: 16.1 %TFC ♂, 19.6 %TFC ♀). In toddlers and preschoolers with overweight or obesity, adherence to dietary recommendations of these food groups was largely similar to that of the total sample. Overall, 5-year-olds showed an unhealthier dietary pattern than 1-year-olds, which already emerged at age 2 years and became more evident at age 3 years. Discussion: An adverse dietary pattern arises and even deteriorates at a very young age, showing sex-specific aspects. High attention from public health and research needs to be given to toddlerhood and even earlier life phases, e.g., to develop more age-specific FBDGs, aiming at reducing unhealthy food consumption.

Marital Conflict and Healthy Dietary Habits Among Preschoolers: A Study of the Experience of Coupled Women in Urban Mexico.

In Mexico social dynamics are changing toward less traditional arrangements. With a qualitative interview study, we explore the link between marital conflict and mothers' ability to foster healthy dietary habits. Sample consisted of 21 middle-class cohabitating mothers of preschoolers. Results suggests that marital conflict leads women to experiences of tension, ambivalence, or inaction on fostering healthy eating habits. Parents' mismatch in gender beliefs, food preferences, time orientation, and risk aversion play a role in creating disagreements. When men participate, women feel "helped" and grateful, but the forms and extent of desired participation may vary among traditional, ambivalent and non-traditional women.

Attention-deficit/hyperactivity disorder (ADHD) in cultural context II: a comparison of the links between ADHD symptoms and waiting-related responses in Hong Kong and UK.

The concept of attention-deficit/hyperactivity disorder (ADHD) is considered to have cross-cultural validity, but direct comparisons of its psychological characteristics across cultures are limited. This study investigates whether preschool children's ADHD symptoms expressed in two cultures with different views about child behaviour and parenting, Hong Kong and the UK, show the same pattern of associations with their waiting-related abilities and reactions, an important marker of early self-regulation. A community sample of 112 preschoolers (mean age = 46.22 months; 55 from UK, 57 from HK) completed three tasks measuring different waiting elements - waiting for rewards, choosing the amount of time to wait, and having to wait unexpectedly when a task is interrupted. Participants' waiting-related behavioural and emotional reactions were coded. Parents rated their children's ADHD symptoms and delay aversion. Our findings revealed that the associations between ADHD symptoms and waiting-related responses were comparable in both UK and HK samples. This suggests that the core psychological characteristics of ADHD, particularly in relation to waiting behaviours, may exhibit similarity across cultural contexts. Future research can extend this cross-cultural analysis to other ADHD-related psychological domains and explore additional cultural settings.
