RESUMO

Children worldwide are becoming increasingly inactive, leading to significant wellness challenges. Initial findings from our research team indicate that robots could potentially provide a more effective approach (compared to other age-appropriate toys) for encouraging physical activity in children. However, the basis of this past work relied on either interactions with groups of children (making it challenging to isolate specific factors that influenced activity levels) or a preliminary version of results of the present study (which centered on just a single more exploratory method for assessing child movement). This paper delves into more controlled interactions involving a single robot and a child participant, while also considering observations over an extended period to mitigate the influence of novelty on the study outcomes. We discuss the outcomes of a two-month-long deployment, during which [Formula: see text] participants engaged with our custom robot, GoBot, in weekly sessions. During each session, the children experienced three different conditions: a teleoperated robot mode, a semi-autonomous robot mode, and a control condition in which the robot was present but inactive. Compared to our past related work, the results expanded our findings by confirming with greater clout (based on multiple data streams, including one more robust measure compared to the past related work) that children tended to be more physically active when the robot was active, and interestingly, there were no significant differences between the teleoperated and semi-autonomous modes in terms of our study measures. These insights can inform future applications of assistive robots in child motor interventions, including the guiding of appropriate levels of autonomy for these systems. This study demonstrates that incorporating robotic systems into play environments can boost physical activity in young children, indicating potential implementation in settings crafted to enhance children's physical movement.

RESUMO

BACKGROUND: Knowledge of developmental trends in meeting age-specific 24-hour movement behaviour guidelines is lacking. This study describes developmental trends in device-measured physical activity and sedentary time over a three-year period among Western Australian children aged two to seven years, including differences between boys and girls. The proportion of children meeting age-specific physical activity guidelines before and after they transition to full-time school was also examined. METHODS: Data from waves 1 and 2 of the Play Spaces and Environments for Children's Physical Activity (PLAYCE) cohort study were used (analysis n = 1217). Physical activity and sedentary time were measured by accelerometry at ages two to five (preschool, wave 1) and ages five to seven (commenced full-time school, wave 2). Accelerometer data were processed using a validated machine-learning physical activity classification model. Daily time spent in sedentary behaviour, energetic play (moderate-to-vigorous physical activity (MVPA)), total physical activity, and meeting physical activity guidelines were analysed using linear and generalised linear mixed-effects models with age by sex interaction terms. RESULTS: All movement behaviours changed significantly with increasing age, and trends were similar in boys and girls. Total daily physical activity increased from age two to five then declined to age seven. Mean daily total physical activity exceeded 180 min/day from ages two to five. Daily energetic play increased significantly from age two to seven, however, was below 60 min/day at all ages except for seven-year-old boys. Daily sedentary time decreased to age five then increased to age seven but remained lower than at age two. All two-year-olds met their age-specific physical activity guideline, decreasing to 5% of girls and 6% of boys at age four. At age seven, 46% of boys and 35% of girls met their age-specific physical activity guideline. CONCLUSIONS: Young children's energetic play and total physical activity increased with age, but few children aged three to seven met the energetic play (MVPA) guideline. Interventions should focus on increasing children's energetic play in early childhood. Clearer guidance and strategies are needed to support young children as they change developmentally and as they transition from one age-specific movement guideline to the next.

RESUMO

OBJECTIVES: To explore the experiences and perceptions of children with bronchiectasis and their parents regarding an 8-week play-based therapeutic exercise programme. DESIGN: Qualitative study with inductive content analysis. SETTING: Individual semistructured interviews were conducted. Interview recordings were transcribed verbatim, and coding was guided by the content. Content categories were established via consensus moderation. PARTICIPANTS: 10 parents and 10 children with bronchiectasis aged 5-12 years. RESULTS: From the perspective of children, the most important components of the programme were fun with friends and being active at home as a family. Parents valued the community-based sessions, perceived the programme to be engaging and motivating. Parents perceived improvements in their child's endurance, coordination and physical activity level. They described the home programme as fun but noted that finding time was difficult. Both parents and children thought that in-person exercise sessions would be better than exercise sessions delivered online. CONCLUSIONS: Children who participated in the play-based exercise programme, found it fun, motivating and accessible. Parents perceived positive impacts on fitness, coordination and physical activity. TRIAL REGISTRATION NUMBER: The trial was registered with, Australian and New Zealand Clinical Trials Register (ACTRN12619001008112).

RESUMO

Heavy metals pose significant threats to human health, particularly children. This study aimed to assess heavy metal pollution in children's playgrounds using surface dust as an indicator and to ascertain the associated exposure levels and health risks. A total of one hundred twenty dust samples were collected from the surface of playground toys in areas surrounding the cement factory in Bursa, Türkiye, on precipitation-free days. The heavy metal content of the samples was analyzed using ICP-MS. The average total concentration of heavy metals ranged from 2401 to 6832 mg/kg across the sampling sites, with the highest values observed at PG4, PG3, PG2, and PG1, respectively. The most commonly detected heavy metals in the samples included Cr, Mn, Fe, Co, Cu, Zn, Pb, Cd, As, and Ni. Statistical analysis revealed significant positive correlations (p < 0.01) among Cr, Mn, Fe, Co, Cu, Pb, As, and Ni, with Cu and Pb also showing correlation (p < 0.05). PCA analysis identified three principal components explaining 79.905% of the total variance. The Hazard Quotient (HQ) and Hazard Index values for heavy metals were found to be below the safe threshold (HQ < 1). Quantitative techniques such as the geoaccumulation index and enrichment factor are used to determine pollution levels at the sampling sites. Overall, the results indicate that cement factories significantly contribute to heavy metal pollution, with observed values varying based on proximity to the emission source.

RESUMO

BACKGROUND: Plastic additives have adverse effects on human health. Children frequently use toys that contain various substances found in paints, plasticizers, and other materials, which heighten the risk of specific chemical exposure. Infants are particularly prone to chemical exposure through the "mouthing" behavior because of the possibility of placing toys in their mouths. Thus, this vulnerability should be considered during risk assessments of chemical exposure. METHODS: This study performed a comprehensive analysis of the chemical components in various 84 plastic toys including "designated toys" (toys that may be harmful to infant health if in contact with their mouths: Article 78 of the Enforcement Regulations of the Food Sanitation Law by the Minister of Health, Labor and Welfare) such as dolls, balls, blocks, bathing toys, toy vehicles, pacifiers, and household items, purchased in the Japanese market by nontargeted and targeted analysis. RESULTS: Plasticizers, flame retardants, and fragrances were the main compounds in almost all the toy products. The results showed that plastic products made in China tended to contain high levels of phthalate esters. In particular, hazardous plasticizers, such as diisodecyl, di-n-octyl, and diisononyl phthalates were detected above the regulatory limit (0.1%) in used products manufactured before regulations were passed in Japan. Furthermore, we detected alternative plasticizers, such as acetyl tributyl citrate (ATBC; 52%), diisononyl adipate (DINA; 50%), and di(2-ethylhexyl) terephthalate (DEHT; 40%). ATBC was detected at high concentrations in numerous toy products. Thus, infants with free access to indoor plastic toys might be exposed to these chemicals. CONCLUSIONS: This study observed that the chemical profiles of toy products were dependent on the year of manufacture. Furthermore, the detection of currently regulated plasticizers in secondhand products manufactured before regulations were enforced, along with the increasing trend of using alternative substances to regulated phthalate esters in products, suggests the potential exposure of infants to these plasticizers through the use of toys. Therefore, regular fact-finding surveys should continue to be conducted for the risk assessment and safety management of domestic toy products.

RESUMO

Phthalates are a family of synthetic chemicals commonly used as plasticizers for polyvinyl chloride-based polymers. They are used in a variety of commercial consumer products, including children's toys. Exposure to phthalates is associated with various adverse health effects, such as developmental and reproductive disorders, liver and kidney toxicity, etc. In the European Union, but also in the Republic of Serbia, restrictions have been imposed on the presence of seven phthalates in toys. In addition, the European Union has established the Rapid Alert System for Dangerous Non-Food Products (RAPEX) to protect consumers across borders by preventing or restricting the sale and use of non-food articles, including children's toys, that pose a significant health and safety risk. In this work, 118 samples of children's toys from the market of the Republic of Serbia were analysed for the presence of all seven restricted phthalates using the HPLC-DAD method. We also comprehensively analysed the RAPEX notifications of toys posing a chemical risk due to the presence of phthalates from 2012 to 2022. In total, 23.7% of the tested toy samples contained one or more phthalates above 0.1% w/w, which corresponds to the legal limit. DEHP was found above the limit in all non-compliant toy samples, followed by DBP, DINP, BBP and DIDP. DIBP and DNOP were not found in any of the samples. In general, phthalates were present in the tested samples in concentrations ranging from

RESUMO

BACKGROUND: Childhood gender nonconformity is related to psychological distress and behavioral difficulties. Similarly, there is evidence for a link between gender nonconformity, or gender dysphoria in some studies, and autism spectrum disorder and related traits. Our knowledge on those associations mostly originates from clinical populations, which might lead to overestimation. Thus, this study aimed to assess associations between gender nonconformity and behavioral difficulties in a population-based study. METHODS: In the Swedish Environmental Longitudinal, Mother and Child, Asthma and Allergy (SELMA) study, cross-sectional associations between gender-specific play behavior and behavioral outcomes and autistic traits were investigated among 718 children at 7-years of age. Play behavior was measured using the Preschool Activities Inventory; behavioral outcomes and autistic traits were measured with the Strengths and Difficulties Questionnaire and the Social Responsiveness Scale, respectively. Linear and logistic regression analyses were performed. RESULTS: Higher composite play behavior scores (indicating either increased masculine or decreased feminine play behavior) were associated with increased autistic trait scores in girls (ß = 0.13; 95% confidence interval [CI] = 0.00, 0.26). Furthermore, higher composite scores were shown to be associated with behavioral difficulties in both girls (ß = 0.11; 95% CI = 0.04, 0.18) and boys (ß = 0.10; 95% CI = 0.02, 0.19). Additionally, higher feminine scores were related with increased problems in peer relationships in boys (ß = 0.04; 95% CI = 0.00, 0.07). CONCLUSIONS: This study suggests a link between gender nonconforming play behavior and autistic traits as well as behavioral difficulties among children in a non-clinical population, which calls attention to the necessity of supporting children with gender nonconformity from early ages.

RESUMO

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.

RESUMO

Despite the growing evidence on the influence of neighborhood safety on physical activity, few studies have specifically focused on preschool-aged children and differentiated the various domains of neighborhood safety. This study investigates the relationship between parental perceptions of neighborhood safety and preschool children's time spent outdoors and explores potential sex differences in this relationship. This study analyzed nationally representative data from 1656 Korean children (848 boys and 808 girls) aged 3, 5, 6 years collected over the course of three waves of the Panel Study on Korean Children (PSKC). Outdoor playtime was measured by maternal reports of the time their children spent playing outdoors on a typical weekday. Parental perceptions of neighborhood safety were assessed using two items that inquired about neighborhood safety in terms of crime and accidents, respectively. Fixed effects estimates revealed that parental perceptions of social safety were associated with an increase in children's outdoor physical activity (b = 3.778, p < 0.05), whereas perceptions of physical safety were not. Sex-stratified models showed that the association between parental perceptions of social safety and children's outdoor play was driven largely by boys (b = 8.498, p < 0.001), with no association observed for girls. The findings of this study underscore the importance of addressing the social safety of neighborhood environments to promote outdoor play in preschool children. Moreover, sex differences should be considered when developing interventions aimed at increasing physical activity among young children.

RESUMO

New high-density polyethylene (HDPE) manufactured from different percentage of post-consumer recycled HDPE milk bottles was studied through two static and dynamic migration tests using saliva simulant to assess the potential hazard to children. Sixty-nine compounds were identified, including several additives used in PE synthesis such as alkanes, alkenes, antioxidants and plasticizers as well as non-intentionally added substances (NIAS) like degradation products such as 2,6-di-tert-butyl-1,4-benzoquinone, 2,4-di-tert-butylphenol, phenol, 2,5-bis(1,1-dimethylethyl)-, 3,5-di-tert-butyl-4-hydroxybenzaldehyde, and 3,5-di-tert-butyl-4-hydroxyacetophenone, or various residues from flavoring agents, cleaning products and essential oils. Some of these compounds as the isomers p and o t-butylcyclohexyl acetate, 3-Octanol, 3,7-dimethyl- and thujanol acetate (3-) pose a potential risk to children, as their concentrations exceed the recommended Cramer values for high percentages of recycling. This suggests improving recycling processes by incorporating advanced cleaning to remove residual products and contaminants.

RESUMO

BACKGROUND: After societal change in Kyrgyz Republic, the pattern of parent-child interaction in the changing parenting culture is an important factor influencing the positive development of Kyrgyz children. This study is aim to assess the quality of parent-child interactions in Kyrgyzstan by analyzing the interaction patterns and playfulness of children during free play at home. METHODS: This was a descriptive pilot study using video-recorded observations to explore parent-child interactions. The Dyadic Parent-Child Interaction Coding System and a playfulness instrument were used to assess the patterns and quality of the interaction. A total of 20 dyads of children aged 24 to 58 months and their parents, living in migrant communities of Kyrgyzstan, participated in this study. RESULTS: Major parent-child interaction patterns included 731 turns of parent-child dyads during 1040 episodes. Verbal as well as nonverbal behaviors of parents were observed while interacting with their children. Parents used direct and indirect commands most frequently, while praise was used the least in interactions. Children frequently used compliance as well as noncompliance when they interacted with their parents. Children had low playfulness scores while interacting with their parents. Cognitive spontaneity was the component with the lowest score among all subdomains of playfulness. CONCLUSION: Future studies are recommended to develop strategies to facilitate parents' active interaction with their children, promote children's playfulness, and improve the quality of their mutual interaction.

RESUMO

BACKGROUND: Children have alarmingly low levels of competency in fundamental motor skills (FMS) and high levels of physical inactivity. e:health interventions, interventions delivered electronically, are useful tools for intervention in the home through parents, but less is known about the effects of these interventions in early childhood education centers or settings. Therefore, we created the Motor skills At Playtime (MAP) e:health intervention (e:MAP) to be delivered in an early childhood education setting. The goals of this pilot study on e:MAP are to (1) determine the intervention effects on children's FMS and physical activity and (2) explore the teachers' perceptions and ability to facilitate e:MAP. METHODS: This pilot study uses a pretest/posttest randomized cluster control design. We will recruit at least 64 children (3.5-5 years of age) enrolled in a single early childhood education center. Children will be randomly assigned at the level of the classroom to an e:MAP group (n~30) or a control group (n~30). Children in classrooms assigned to e:MAP will complete an 8-week intervention. We will collect measures of child FMS and physical activity, and teacher's perceptions of the program before (pretest) and after the intervention (posttest). FMS measures include process (Test of Gross Motor Development-3rd Edition) and product-oriented scores. Physical activity will be assessed using a 7-day accelerometer wear protocol. Teachers' perceptions will be assessed through a brief survey. Lastly, we will collect data on teachers' ability to facilitate e:MAP through a daily survey. POTENTIAL SIGNIFICANCE: This study will yield novel insights into the effectiveness and feasibility of a health intervention in an early childhood education setting. Results from this work will expand our knowledge of how to harness e:health modalities, which have the potential to significantly expand the distribution and scalability of FMS interventions.

RESUMO

PURPOSE: The aim of this study is to examine the effects of preoperative therapeutic play on fear and anxiety levels in preschool children. DESIGN AND METHODS: The study had an experimental pre-intervention-post-intervention design with a control group. The study was carried out with 37 children aged 3-6 years who were brought for surgical procedures at XX Research and Training Hospital between July 2020 and January 2021. While a therapeutic play intervention was performed with the children in the experimental group (n = 20), routine preoperative practices were performed in the control group (n = 17). Data were analyzed using chi-squared tests, the Mann-Whitney U test, and the Wilcoxon test. p < 0.05 was considered significant. RESULTS: The fear and anxiety levels of the children in the experimental and control groups were similar pre-intervention (p > 0.05). In the post-intervention, the mean anxiety and fear scores of the experimental group were 2.15 ± 1.63 and 1.15 ± 0.58, their mean ranks were 10.80 and 12.65, while the mean anxiety and fear scores of the control group were 7.94 ± 2.07 and 2.53 ± 1.00, their mean ranks were 28.65 and 26.47, respectively, and the difference between the groups was statistically significant (respectively, MU = 6.00 p = 0.000, MU = 43.00 p = 0.000). CONCLUSION: It was determined that the therapeutic play method applied before surgery reduced the anxiety and fear levels of children. Considering this situation, improving the skills of nurses in therapeutic play and increasing the number of personnel certified for interactive therapeutic games can reduce the risk of preoperative emotional trauma in children. PRACTICE IMPLICATIONS: The therapeutic play method applied before surgery reduced the anxiety and fear levels of children. The routine use of therapeutic play in pediatric surgery clinics is recommended.

RESUMO

Infant behaviors-walking, vocalizing, playing, interacting with others, and so on-offer an unparalleled window into learning and development. The study of infants requires strategic choices about what to observe, where, when, and how. We argue that loosening study constraints-by allowing infants and caregivers to do whatever they choose, wherever they choose, and with whatever materials they choose-promises to reveal a deep understanding of the everyday data on which learning builds. We show that observations of infants' natural behavior yield unique insights into the nature of visual exploration, object play, posture and locomotion, proximity to caregiver, and communication. Furthermore, we show that by situating the study of behavior in ecologically-valid settings, researchers can gain purchase on the contextual regularities that frame learning. We close by underscoring the value of studies at every point on the research continuum-from cleverly controlled lab-based tasks to fully natural observations in everyday environments. Acceleration in the science of behavior rests on leveraging expertise across disciplines, theoretical positions, and methodological approaches.

RESUMO

Puberty is a period of brain organization impacting the expression of social and sexual behaviors. Here, we assessed the effects of an acute pubertal stressor (immune challenge) on the expression of juvenile play (short-term) and sexual partner preference (long-term) in male rats. Juvenile play was assessed over ten trials at postnatal days (PND) (31-40) with age- and sex-matched conspecifics, and at PND35 males received a single injection of lipopolysaccharide (LPS, 1.5 mg/kg i.p.) or saline. Then, sexual partner preference was assessed at PND 60, 64, and 68, in a three-compartment chamber with a sexually receptive female and a male as potential partners simultaneously. The results confirmed that a single injection of LPS during puberty induced sickness signs indicative of an immune challenge. However, juvenile play was not affected by LPS treatment during the following days (PND36-40), nor was sexual behavior and partner preference for females in adulthood. These findings highlight that, while other studies have shown that LPS-induced immunological stress during puberty affects behavior and neuroendocrine responses, it does not affect juvenile play and sexual behavior in male rats. This suggests a remarkable resilience of these behavioral systems for adaptation to stressful experiences mediated by immune challenges during critical periods of development. These behaviors, however, might be affected by other types of stress.

RESUMO

BACKGROUND: Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental conditions in children, and can profoundly affect their social interactions, well-being, and relationships with parents, peers, and teachers. OBJECTIVE: This study investigated the effectiveness of a social-play-based intervention programme in reducing ADHD symptoms in a sample of 67 Saudi boys aged 8-10 diagnosed with ADHD. METHODS: The programme consisted of ten 60-minute sessions of play-based activities, delivered to the experimental group twice weekly for 5 weeks. The control group followed the usual school curriculum. Teachers and parents completed the Conners' Teacher Rating Scale-Revised: Short Form and Conners' Parent Rating Scale-Revised: Short Form for all participants at pre-test, post-test, and follow-up. RESULTS: The experimental group showed a significant reduction in ADHD-associated behavioural problems over time, with moderate to large effect sizes. No significant changes over time were found for the control group. The results were maintained at a 2-month follow-up. CONCLUSIONS: We recommend incorporating social-play-based activities and skill training into the school context. Reducing ADHD symptoms may improve children's academic performance and perspective on school.

RESUMO

OBJECTIVES: to identify content on play and interaction with children with special health care needs recommended in clinical guidelines; analyze play and interaction activities applicable to children with special health care needs and complex care requirements. METHOD: qualitative documentary research based on guides, protocols, or guidelines on playing and interacting with children with special and living with complex care. Search terms in English (guidelines, playing OR play, complex needs, OR chronic disease) and in Portuguese ( guia, brincar ou brincadeiras, condições crônicas ) on the first ten pages of_Google Search ® . Thematic analysis was applied to the information extracted from the documents. RESULTS: a total of nine documents with similar content were grouped into units of analysis, keeping only the interacting and playing activities applicable to children with special health care needs and living with complex care requirements, namely stimulation of potential, stimulation of adult-child interaction, and stimulation of the senses (touch, sight, and hearing), to be carried out by health professionals and family caregivers in the different care contexts. CONCLUSION: interaction and play are potential promoters of adult-child interaction, with application in the stimulating and life-delivering complex care for children.
