Asthma development is associated with low mucosal IL-10 during viral infections in early life.

BACKGROUND: Viral infection is a common trigger of severe respiratory illnesses in early life and a risk factor for later asthma development. The mechanism leading to asthma could involve an aberrant airway immune response to viral infections, but this has rarely been studied in a human setting. OBJECTIVES: To investigate in situ virus-specific differences in upper airway immune mediator levels during viral episodes of respiratory illnesses and the association with later asthma. METHODS: We included 493 episodes of acute respiratory illnesses in 277 children aged 0-3 years from the COPSAC2010 mother-child cohort. Levels of 18 different immune mediators were assessed in nasal epithelial lining fluid using high-sensitivity MesoScale Discovery kits and compared between children with and without viral PCR-identification in nasopharyngeal samples. Finally, we investigated whether the virus-specific immune response was associated with asthma by age 6 years. RESULTS: Viral detection were associated with upregulation of several Type 1 and regulatory immune mediators, including IFN-É£, TNF-α, CCL4, CXCL10 and IL-10 and downregulation of Type 2 and Type 17 immune mediators, including CCL13, and CXCL8 (FDR <0.05). Children developing asthma had decreased levels of IL-10 (FDR <0.05) during viral episodes compared to children not developing asthma. CONCLUSION: We described the airway immune mediator profile during viral respiratory illnesses in early life and showed that children developing asthma by age 6 years have a reduced regulatory (IL-10) immune mediator level. This provides insight into the interplay between early-life viral infections, airway immunity and asthma development.

Malocclusion in deciduous dentition: a cross-sectional study in a Portuguese preschool population.

PURPOSE: To determine the prevalence of malocclusion in Portuguese preschool children, to characterise occlusion in the deciduous dentition, and to study the relationship between malocclusion, sex, and age. METHODS: This cross-sectional study included 3-6 years old children, from 25 randomly selected kindergartens from the Lisbon district. Data were collected through an oral examination. Malocclusion was defined as the presence of any type of occlusion anomaly (anterior crossbite, edge-to-edge, increased overjet, open bite, deep overbite, posterior crossbite, scissor bite), spacing anomaly (crowding), or dentition anomaly (supernumerary teeth, agenesis, malformations). Canine class, terminal plane of the deciduous second molars and type of Baume arch were also recorded. Statistical analysis included descriptive and chi-squared test (α = 0.05). RESULTS: The sample included 426 children with a global prevalence of malocclusion of 60.6%. Occlusion anomalies were the most prevalent (59.2%), the most frequent being deep overbite (27%), increased overjet (22.1%) and posterior crossbite (14.1%). Crowding had a prevalence of 1.6% and agenesis of 1.4%. Class I canine (57.3%), straight second molar terminal plane (60.1%) and type I Baume arch (53.3%) were the most common. The mean overjet was 2.6 mm (sd = 2.1) and the mean overbite was 2.2 mm (sd = 2.1). Age was associated with the presence of occlusion anomalies (p = 0.03), and increased overjet prevalence was found to be higher in girls (p = 0.03). CONCLUSIONS: The prevalence of malocclusion was high, with occlusion anomalies being the most prevalent. It is important to identify modifiable risk factors associated with malocclusion to prevent this condition in both the deciduous and permanent dentitions.

Children's injuries in legislated types child-care institutions.

BACKGROUND: Severe injuries in child-care institutions are an important social issue. However, no reports on this matter have been made in Japan. This study examined trends in severe injuries at child-care institutions, including the impact of the coronavirus disease 2019 (COVID-19) pandemic. METHODS: We conducted a serial cross-sectional study and interrupted time-series (ITS) analysis with a linear regression model to assess trends in the incidence rate of severe injuries using Japanese national open data between January or April 2017 and December 2021. Participants were individuals utilizing legislated types child-care institutions. The outcomes were annual and monthly incidence rates of severe injuries in legislated types child-care institutions. RESULTS: The number of legislated types child-care institutions increased from 32,793 facilities in 2017 to 38,666 facilities in 2021, and the number of participants rose from 2,802,228 in 2017 to 3,059,734 in 2021. The annual incidence rate of severe injuries in 2021 was 58.3 cases per 100,000 person-years, which is twofold higher than that in 2017. The ITS for the monthly incidence rate demonstrated an increasing trend before the COVID-19 pandemic. CONCLUSIONS: Before the COVID-19 pandemic, the monthly incidence rate of severe injuries in legislated types child-care institutions increased. The annual incidence rate in Japan may have also increased during the observation period.

Use of Child Safety Seat and its Determinants in Jeddah, Saudi Arabia: A Cross-sectional Study.

Background: A child safety seat protects children from injury during motor vehicle accidents (MVAs). However, there is a lack of enforcement of regulation regarding its use in Saudi Arabia. Objectives: This study aimed to determine the use of child safety seat and its determinants and barriers in Jeddah, Saudi Arabia. Materials and Methods: This cross-sectional study was based on a structured face-to-face interview across Jeddah among families who drove in cars with children aged ≤5 years. The study used stratified multistage random sampling across the population of the governorate of Jeddah. Results: A total of 675 parents were included, of which 311 (46.1%) reported having a child safety seat in their vehicle, and only 165 (24.4%) reported its regular use. Awareness levels among parents regarding child safety seat use and its benefits, parents' level of education, family size, family income, and the belief in the need for laws governing child safety seat were key determinants of child safety seat use. Poor awareness among parents regarding the utility of child safety seat in reducing child injuries, low education levels among parents, larger families with multiple children, poor affordability, low family income, and a clear lack of laws mandating the use of child safety seat were identified as key barriers. Conclusions: The regular use of child safety seat for children aged ≤5 years is low in even one of the most urban populations of Saudi Arabia. This indicates the need for large-scale awareness drives and stricter implementation of laws enforcing the use of child safety seat in Saudi Arabia.

Relationship between sleep disturbance and developmental status in preschool-aged children with developmental disorder.

BACKGROUND: Sleep has been known to affect childhood development. Sleep disturbance is likely more common in children with developmental delay (DD) than in typical development. There are few studies on the correlation between sleep disturbance and developmental features in children with DD. Therefore, this study aimed to evaluate the associations between the two in children with DD. METHODS: A total of 45 children (age range 27.0 ± 11.1) with DD were recruited and evaluated using the Sleep Disturbance Scale for Children (SDSC) and Bayley Scales of Infant and Toddler Development (BSID-III). The outcomes are expressed as means and standard deviations. The correlation between SDSC and BSID-III was assessed using Spearman's rank correlation test. Multiple regression analysis was performed to investigate the relationship between BSID-III domains and SDSC questionnaire subscales. Statistical significance was set at p < 0.05. RESULTS: Based on the correlation analysis and subsequent hierarchical regression analysis, cognition and socio-emotional domains of BSID-III were significantly associated with the DOES subscale of the SDSC questionnaire. In addition, the expressive language domain of the BSID-III was found to be associated with the DA subscale of the SDSC questionnaire. It seems that excessive daytime sleepiness might negatively affect emotional and behavioral problems and cognitive function. Also, arousal disorders seem to be related to memory consolidation process, which is thought to affect language expression. CONCLUSION: This study demonstrated that DA and DOES subscales of the SDSC questionnaire were correlated with developmental aspects in preschool-aged children with DD. Sleep problems in children with DD can negatively affect their development, thereby interfering with the effectiveness of rehabilitation. Identifying and properly managing the modifiable factors of sleep problems is also crucial as a part of comprehensive rehabilitation treatment. Therefore, we should pay more attention to sleep problems, even in preschool-aged children with DD.

Independent and Joint Effects of Prenatal Incense-Burning Smoke Exposure and Children's Early Outdoor Activity on Preschoolers' Obesity.

Incense burning is a significant source of indoor air pollution in many Asian regions. There is emerging evidence that maternal prenatal exposure to incense-burning smoke may be a risk factor for childhood obesity. We aimed to extend this new line of research by investigating the independent and joint effect of incense-burning smoke exposure, and children's outdoor activity in early life, on preschoolers' obesity. A total of 69,637 mother-child dyads were recruited from all kindergartens in the Longhua District of Shenzhen, China. Information on sociodemographic characteristics, maternal exposure to incense-burning smoke (IBS) during pregnancy, and frequency and duration of outdoor activity at the age of 1-3 years was collected by a self-administered questionnaire. In addition, the heights and weights of the children were measured by the research team. Logistic regression models and cross-over analyses were conducted to investigate the independent and combined effects of maternal exposure to incense-burning smoke during pregnancy and children's early outdoor activity on obesity in preschoolers. We found that prenatal exposure to incense-burning smoke increased the risk of the presence of obesity in preschoolers' (AOR = 1.13, 95% CI = 1.03-1.23). Additionally, lower frequencies (<3 times/week) or shorter durations (<60 min/time) of outdoor activity from the age of 1-3 years were significantly associated with the presence of obesity, with AORs of 1.24 (95% CI =1.18-1.32) and 1.11 (95% CI = 1.05-1.17), respectively. Furthermore, the cross-over analysis showed that prenatal exposure to IBS combined with a lower frequency of early outdoor activity (AOR = 1.47, 95% CI = 1.31-1.66) or a shorter duration of outdoor activity during ages of 1-3 years (AOR = 1.22, 95% CI = 1.07-1.39) increased the risk of obesity in preschoolers. Finally, additive interactions between prenatal exposure to IBS and postnatal outdoor activity on obesity were identified. Our study indicates that maternal exposure to incense-burning smoke during pregnancy and early lower postanal outdoor activity may independently and jointly increase the risk of obesity among preschoolers.

Eating Habits and Lifestyle Factors Related to Childhood Obesity Among Children Aged 5-6 Years: Cluster Analysis of Panel Survey Data in Korea.

BACKGROUND: Childhood obesity has emerged as a major health issue due to the rapid growth in the prevalence of obesity among young children worldwide. Establishing healthy eating habits and lifestyles in early childhood may help children gain appropriate weight and further improve their health outcomes later in life. OBJECTIVE: This study aims to classify clusters of young children according to their eating habits and identify the features of each cluster as they relate to childhood obesity. METHODS: A total of 1280 children were selected from the Panel Study on Korean Children. Data on their eating habits (eating speed, mealtime regularity, consistency of food amount, and balanced eating), sleep hours per day, outdoor activity hours per day, and BMI were obtained. We performed a cluster analysis on the children's eating habits using k-means methods. We conducted ANOVA and chi-square analyses to identify differences in the children's BMI, sleep hours, physical activity, and the characteristics of their parents and family by cluster. RESULTS: At both ages (ages 5 and 6 years), we identified 4 clusters based on the children's eating habits. Cluster 1 was characterized by a fast eating speed (fast eaters); cluster 2 by a slow eating speed (slow eaters); cluster 3 by irregular eating habits (poor eaters); and cluster 4 by a balanced diet, regular mealtimes, and consistent food amounts (healthy eaters). Slow eaters tended to have the lowest BMI (P<.001), and a low proportion had overweight and obesity at the age of 5 years (P=.03) and 1 year later (P=.005). There was a significant difference in sleep time (P=.01) and mother's education level (P=.03) at the age of 5 years. Moreover, there was a significant difference in sleep time (P=.03) and the father's education level (P=.02) at the age of 6 years. CONCLUSIONS: Efforts to establish healthy eating habits in early childhood may contribute to the prevention of obesity in children. Specifically, providing dietary guidance on a child's eating speed can help prevent childhood obesity. This research suggests that lifestyle modification could be a viable target to decrease the risk of childhood obesity and promote the development of healthy children. Additionally, we propose that future studies examine long-term changes in obesity resulting from lifestyle modifications in children from families with low educational levels.

Early Childhood Oral Health Impact Scale: Psychometric Evaluation in Portuguese Preschoolers.

Objective: to contribute to the validation of the Early Childhood Oral Impact Scale (ECOHIS) by studying its psychometric properties when applied to a Portuguese preschool population. Methods: Cross-sectional study conducted with children aged between three and five-years-old. The non-probabilistic sample included two preschools in the municipality of Lisbon. Children who agreed to participate and whose guardians signed the informed consent were included. Data collection included a questionnaire, administered to the parents, and an intraoral examination of the children. The questionnaire included the Portuguese version of ECOHIS. The intraoral examination included the caries diagnosis according to the World Health Organization criteria. Discriminant validity compared the ECOHIS score between children with and without caries experience (Mann-Whitney U-test). Cohen's d was calculated to estimate the magnitude of the difference. Reliability analysis included Cronbach's α and test-retest. Construct validity was analyzed by the correlation between the ECOHIS score and dmft (Spearman's correlation). A significance level of 5% was used. Results: The sample included 104 children (mean age 4.1 years). ECOHIS values were significantly different between children with and without caries (p=0.004). The Cohen's d was 0.84. The Cronbach's was 0.78, with no significant increase in value when eliminating any of the items. The test-retest showed significant correlation (r=0.76; p=0.01). There was a significant correlation between the ECOHIS score and caries experience (r=0.28; p=0.004). Conclusion: The Portuguese version of the ECOHIS showed good psychometric properties, indicating that it is a reliable and valid tool to measure the impact of oral health in preschool children.

Análisis de meriendas escolares: estudio piloto en educación infantil / School meals analysis: pilot study in early childhood education

Fundamentos: La escuela puede ser un contexto favorecedor para prevenir la obesidad infantil, por lo que pautar meriendas escolares puede contribuir a adoptar hábitos saludables. El objetivo de este estudio fue doble: a) analizar el grado de cumplimiento de las meriendas pautadas; b) comparar las características de las meriendas según si eran o no pautadas. Métodos: Estudio transversal donde han participado centros escolares de las ciudades de Vigo y Pontevedra. Para el análisis comparativo se clasificó y categorizó cada una de las meriendas de los centros con y sin pauta. Asimismo, se comparó la composición de las meriendas establecidas, dependiendo si habían cumplido o no la pauta. Resultados: Se analizaron 1259 meriendas establecidas y 1363 sin pauta. El 81,2% de las meriendas recogidas cumplían con los requisitos pautados. Las meriendas no establecidas incluyeron un número de alimentos significativamente superior (p<0,001), así como un mayor porcentaje de alimentos ultraprocesados. En los centros con pauta, los niños cumplidores incluían más fruta y embutido, mientras que los no cumplidores llevaban más ultraprocesados. Conclusiones: Pautar meriendas escolares en educación infantil es una estrategia efectiva para asegurar una nutrición variada y una menor ingesta de alimentos ultraprocesados. (AU)

Background: The school can be a favorable context to prevent childhood obesity, so that the pattern of school snacks can contribute to the adoption of healthy habits. The aim of this study was twofold: a) to analyze the degree of compliance with the prescribed snacks; b) to compare the characteristics of the snacks according to whether they were prescribed or not. Methods: Cross-sectional study in which schools in the cities of Vigo and Pontevedra participated. For the comparative analysis, we classified and categorized each of the snacks in the schools with and without guidelines. Likewise, the composition of the established snacks was compared, depending on whether or not they had complied with the guideline. Results: A total of 1259 established snacks and 1363 without guidelines were analyzed. Of the snacks collected, 81.2% complied with the requirements established. The non-established snacks included a significantly higher number of foods (p<0.001), as well as a higher percentage of ultra-processed foods. In guideline centers, compliant children included more fruit and sausage, while non-compliant children had more ultra-processed foods. Conclusions: The school snack program in early childhood education is an effective strategy to ensure avaried nutrition and a lower intake of ultra-processed foods. (AU)

The preparation of children for day surgery from the parent's viewpoint: A mixed methods study.

AIM: The purpose of the study was to describe the preparation of children for day surgery from the parent's viewpoint. DESIGN: Empirical Research Mixed Method. METHODS: The research applied a mixed-methods study design. The study was conducted at the Paediatric Day Surgical Department of one REDACTED between 2018 and 2020 at the same time as an associated randomised controlled conduct trial. Parents of 41 children (ages 2-6 years) completed measures assessing their preparation for day surgery and satisfaction with the procedure. Semi-structured interviews were conducted with 15 parents to better understand their experiences. RESULTS: According to the results, most of the parents (95%) told their children about the upcoming day surgery procedure. The child was prepared for the surgery with cognitive and sensory information, and the preparation usually started at home well before the surgery. The parents' experiences with the most critical aspects of preparing their child included three main categories: (1) usability of the preparation method; (2) content and timing of the preparation method and (3) consideration of the family perspective.

[Association between auditory processing and problem behaviors in preschool children: the mediating role of executive function]. / å¬å¤„ç†ä¸Žå­¦é¾„å‰å„¿ç«¥é—®é¢˜è¡Œä¸ºçš„å ³ç³»ï¼šæ‰§è¡ŒåŠŸèƒ½çš„ä¸­ä»‹ä½œç”¨.

OBJECTIVES: To investigate the association between auditory processing and problem behaviors in preschool children, as well as the mediating role of executive function. METHODS: A total of 2 342 preschool children were selected from 7 kindergartens in Nanjing, China from June to August 2021. They were evaluated using Preschool Auditory Processing Assessment Scale, Conners Parent Symptom Questionnaire, and Behavior Rating Inventory of Executive Functioning-Preschool version. Children with different demographic features were compared in the scores and the abnormality rates of auditory processing, problem behaviors, and executive function. The influencing factors of the total scores of auditory processing, problem behaviors, and executive function were evaluated using multiple linear regression analysis. Whether executive function was a mediating factor between auditory processing and executive function was examined. RESULTS: Sex and grade were the main influencing factors for the total score of auditory processing (P<0.05), and sex, grade, parental education level, and family economic status were the main influencing factors for the total scores of problem behaviors and executive function (P<0.05). The auditory processing score (rs=0.458, P<0.05) and problem behavior score (rs=0.185, P<0.05) were significantly positively correlated with the executive function score, and the auditory processing score was significantly positively correlated with the problem behavior score (rs=0.423, P<0.05). Executive function played a partial mediating role between auditory processing and problem behaviors, and the mediating effect accounted for 33.44% of the total effect. CONCLUSIONS: Auditory processing can directly affect the problem behaviors of preschool children and indirectly affect problem behaviors through executive function.

Differences in Motor Development between Preterm Infants and Full-Term Preschool Children.

Although advances in obstetric and neonatal care have improved the survival of preterm infants, many studies document the increased risk of motor and sensory neurodevelopmental abnormalities that can hinder school progress. The aim of this study was to analyze the differences in gross and fine motor development in children born preterm and full term aged 3 to 6 years using the Peabody Developmental Motor Scales 2 (PDMS-II). Fifteen preterm and fifteen term children, matched for age and sex, participated in this study. They were evaluated with the PDMS-II scale. The scores obtained in the PDMS-II scale showed statistically significant differences (p < 0.05) in all subscales except for the "grasping" subscale. No dissimilarities were found between children who attended an early intervention program and those who did not participate, nor was there any correlation between week of gestation and birth weight and motor development in preschool. The results obtained show that differences are found with respect to motor development, with lower scores for those born preterm compared to children born at term. No statistically significant difference was found between preterm children who attended early intervention and those who did not. No correlation was found between motor development at preschool age and birth weight and gestational age.

Determining optimal cuff volume for cuffed endotracheal tubes commonly used in pediatric patients: A prospective observational study.

OBJECTIVES: To determine an optimal cuff inflation volume to achieve safe cuff pressure (20-25 cmH2O) in cuffed endotracheal tubes (ETTs) with an inner diameter of 4.5, 5.0, and 5.5 mm, which are commonly used in pediatric anaesthesia clinical practice and to create a formula to determine the optimal cuff volume. METHODS: This study was carried out between February and June 2021 in Ankara City Hospital, Ankara, Turkey. A total of 127 pediatric patients who were intubated with 4.5, 5.0 and 5.5 numbered cuffed ETTs were included in this study. The same brand of cuffed ETT was used for each patient. The diameter of the subglottic transverse airway was measured by ultrasound for selecting the appropriate tube. Cuff pressure was measured with a cuff manometer to ensure optimum cuff pressure (20-25 cmH2O). RESULTS: We found out that the mean ideal cuff volume inflated for 4.5 size tube was 1.7±0.3 ml, 1.9±0.3 ml for 5.0 size tube, and 2.1±0.3 ml for 5.5 size tube. Additionally we developed the "endotracheal cuff volume (ml) = 1,027 x height (m) + 0,104 x subglottic transverse diameter (mm) - 0,0191" formula to predict the most suitable inflation volume for ETT cuffs. CONCLUSION: In this study, we suggested the optimal cuff volume to inflate the cuffs of ETTs 4.5, 5.0, and 5.5, which are frequently used in pediatric anaesthesia practice, in the appropriate cuff pressure range.ClinicalTrials.gov ref. no.: NCT04948359.

Key risk factors of asthma-like symptoms are mediated through infection burden in early childhood.

BACKGROUND: Risk factors of asthma-like symptoms in childhood may act through an increased infection burden because infections often trigger these symptoms. OBJECTIVE: We sought to investigate whether the effect of established risk factors of asthma-like episodes in early childhood is mediated through burden and subtypes of common infections. METHODS: The study included 662 children from the Copenhagen Prospective Studies on Asthma in Childhood 2010 mother-child cohort, in which infections were registered prospectively in daily diaries from age 0 to 3 years. The association between established risk factors of asthma-like episodes and infection burden was analyzed by quasi-Poisson regressions, and mediation analyses were performed for significant risk factors. RESULTS: In the first 3 years of life, the children experienced a median of 16 (interquartile range, 12-23) infectious episodes. We found that the infection burden significantly (PACME < .05) mediated the association of maternal asthma (36.6% mediated), antibiotics during pregnancy (47.3%), siblings at birth (57.7%), an asthma exacerbation polygenic risk score (30.6%), and a bacterial airway immune score (80.2%) with number of asthma-like episodes, whereas the higher number of episodes from male sex, low birth weight, low gestational age, and maternal antibiotic use after birth was not mediated through an increased infection burden. Subtypes of infections driving the mediation were primarily colds, pneumonia, gastroenteritis, and fever, but not acute otitis media or acute tonsillitis. CONCLUSIONS: Several risk factors of asthma-like symptoms in early childhood act through an increased infection burden in the first 3 years of life. Prevention of infectious episodes may therefore be beneficial to reduce the burden of asthma-like symptoms in early childhood.

Application of continuous nursing based on EMS management mode in preschool children with wheezing diseases / 上海交通大学学报（医学版）

Objective·To explore the effect of continuous nursing based on EMS[environment management(E),medicine direction(M)and self monitoring(S)]management mode on the preschool children with asthmatic diseases.Methods·A total of 67 children aged 0 to 6 years with asthmatic diseases admitted to the Department of Respiratory Medicine,Shanghai Children's Hospital,Shanghai Jiao Tong University School of Medicine from December 2019 to November 2020 were selected and divided into observation group(33 cases)and control group(34 cases)according to the random number table method,with 3 cases lost,and finally 32 cases in each group.The observation group received continuous nursing care based on EMS management mode,while the control group received routine care and discharge follow-up through the telephone.The children in the two groups were followed up at 1,3,and 6 months after discharge to evaluate the results of Test for Respiratory and Asthma Control in Kids(TRACK)and wheezing recurrence;Medication Adherence Report Scale for Asthma(MARS-A)and Nursing Job Satisfaction Questionnaire were used to evaluate medication adherence and nursing job satisfaction 6 months after discharge.Results·There was no significant difference in demographic characteristics and clinical baseline characteristics between the two groups.Repeated measures analysis of variance showed that effects of time,groups and the interaction of groups×time on the total score of TRACK were statistically significant.The total scores of TRACK in the observation group were significantly higher than those in the control group at 1,3,and 6 months after discharge(P=0.000).The total scores of TRACK in the two groups gradually increased with time(P=0.000).The recurrence rates of wheezing in the observation group were 25.0%,18.7%,and 9.4%at 1,3,and 6 months after discharge,which were significantly lower than those in the control group(50.0%,43.7%,and 31.3%,respectively,P<0.05).Generalized estimating equation analysis showed that there was a statistically significant difference between the two groups(P=0.013),and the intervention effect of the observation group was better than that of the control group(OR=0.292).The MARS-A score of the observation group was 4.519±0.395 at 6 months after discharge,which was significantly higher than that of the control group(3.994±0.739,P=0.001).The nursing job satisfaction of the observation group was significantly higher than that of the control group(P=0.000).There was a moderate positive correlation between the MARS-A score and the nursing job satisfaction(r=0.389,P=0.001).Conclusion·Continuous nursing based on EMS management mode can significantly improve the medication compliance and wheezing control level of the preschool children with asthmatic diseases,significantly reduce the recurrence rate of wheezing,and improve the nursing satisfaction.

Screen Time and Socioemotional and Behavioural Difficulties Among Indigenous Children in Canada: Temps d'écran et difficultés socio-émotionnelles et comportementales chez les enfants autochtones du Canada.

OBJECTIVES: To describe screen time levels and determine their association with socioemotional and behavioural difficulties among preschool-aged First Nations, Métis, and Inuit children. METHOD: Data were taken from the Aboriginal Children's Survey, a nationally representative survey of 2-5-year-old Indigenous children in Canada. Socioemotional and behavioural difficulties were defined using parent/guardian reports on the Strengths and Difficulties Questionnaire. Multiple linear regression analyses were conducted separately for First Nations, Métis, and Inuit participants, and statistically adjusted for child age, child sex, and parent/guardian education. Statistical significance was set at P < 0.002 to adjust for multiple comparisons. RESULTS: Of these 2-5-year-old children (mean [M] = 3.57 years) 3,085 were First Nations (53.5%), 2,430 Métis (39.2%), and 990 Inuit (7.3%). Screen time exposure was high among First Nations (M = 2 h and 58 min/day, standard deviation [SD] = 1.89), Métis (M = 2 h and 50 min [SD = 1.83]), and Inuit children (M = 3 h and 25 min [SD = 2.20]), with 79.7% exceeding recommended guidelines (>1 h/day). After adjusting for confounders, screen time was associated with more socioemotional and behavioural difficulties among First Nations (total difficulties ß = 0.15 [95% CI, 0.12 to 0.19]) and Métis (ß = 0.16 [95% CI, 0.12 to 0.20]) but not Inuit children (ß = 0.12 [95% CI, 0.01 to 0.23]). CONCLUSIONS: Screen time exposure is high among Indigenous children in Canada, and is associated with more socioemotional and behavioural difficulties among First Nations and Métis children. Contributing factors could include enduring colonialism that resulted in family dissolution, lack of positive parental role models, and disproportionate socioeconomic disadvantage. Predictors of poor well-being should continue to be identified to develop targets for intervention to optimize the health and development of Indigenous children.

Risco de distúrbio alimentar Pediátrico em pré-escolares nascidos prematuros / Risk of pediatric eating disorders in preschoolers born prematurely

RESUMO Objetivo verificar o risco de distúrbio alimentar pediátrico em pré-escolares que nasceram prematuros e relacionar com os aspectos neonatais, de aleitamento materno e de hábitos orais. Métodos estudo descritivo e longitudinal. A amostra foi composta por pré-escolares que nasceram prematuros e que foram acompanhados até os 24 meses de idade corrigida. A coleta de dados consistiu em análise de prontuários, entrevista e aplicação da Escala Brasileira de Alimentação Infantil. Resultados participaram 19 pré-escolares, com média de idade de 5 anos e 1 mês, nascidos prematuros (idade gestacional de 32 semanas), saudáveis e com função motora oral normal aos 2 anos de idade corrigida. A aplicação da escala permitiu identificar risco de distúrbio alimentar pediátrico em 31,57% da amostra. Não houve diferença entre os grupos com e sem risco do distúrbio quanto às variáveis neonatais, de aleitamento materno e de hábitos orais. Apenas a variável tempo de transição alimentar no período de internação neonatal apresentou diferença entre os grupos, sendo maior em crianças que não apresentaram risco para o distúrbio. Conclusão O risco de distúrbio alimentar pediátrico ocorreu em quase um terço dos prematuros em idade pré-escolar. O tempo de transição alimentar no período de internação neonatal foi a única variável que apresentou diferença entre os grupos com e sem risco para o distúrbio. Assim, pode-se refletir que o momento de introdução da alimentação oral e a forma de progressão da dieta até a via oral plena na internação neonatal podem ter relação com o comportamento alimentar em outras fases do desenvolvimento infantil.

ABSTRACT Purpose To verify the risk of pediatric eating disorders in preschoolers who were born prematurely and relate it to neonatal aspects, breastfeeding and oral habits. Methods Descriptive and longitudinal study. The sample was made up of preschoolers who were born prematurely and who were followed up until 24 months of corrected age. Data collection consisted of analysis of medical records, interviews and application of the Brazilian Infant Feeding Scale (EBAI). Results 19 preschoolers participated, with a mean age of 5.11±0.51, born prematurely (gestational age of 32.05 ± 3.26 weeks), healthy and with normal oral motor function at 2 years of corrected age. The application of the EBAI made it possible to identify the risk of pediatric eating disorders in 31.57% of the sample. There was no difference between the groups with and without risk of pediatric eating disorders regarding neonatal variables, breastfeeding and oral habits. Only the variable feeding time during the neonatal hospitalization period showed a difference between the groups, being higher in children who were not at risk for pediatric eating disorders. Conclusion The risk of pediatric eating disorders occurred in almost a third of pre-school-age premature infants. The dietary transition time during the neonatal hospitalization period was the only variable that showed a difference between the groups with and without risk of pediatric eating disorders. Thus, one may consider that, the moment of introduction of oral feeding and the way in which the diet progresses until the full oral route, during neonatal hospitalization, may be related to eating behavior in other phases of child development.

Factors influencing Tanzanian mothers' feeding practices for toddlers: A predictive correlational study.

Background: Feeding practices are crucial in ensuring toddlers receive an appropriate and varied diet to support their growth and development. In Tanzania, maternal feeding practices for young children are inadequate, and there is limited research on the influencing factors. Objective: This study aimed to examine the factors influencing Tanzanian mothers' feeding practices for toddlers, utilizing the health promotion model as the theoretical framework. Methods: A predictive correlational design was employed, with a random sample of 399 mothers who brought their toddlers for health supervision at a tertiary care hospital in the United Republic of Tanzania. Data on personal information, depression, perceived benefits, perceived barriers, perceived self-efficacy, social support, situational influences, and maternal feeding practices were collected using self-administered questionnaires between September 2021 and November 2021. Descriptive statistics, correlations, and multiple regression analysis were employed for the analysis. Results: All the factors examined in the study accounted for 18.9% of the variance explained in maternal feeding practices. Significantly, only two factors, perceived self-efficacy (ß = 0.32, p <0.001) and situational influences (ß = 0.24, p <0.001), could predict maternal feeding practices. Conclusion: Perceived self-efficacy and situational influences emerged as the primary influencing factors on maternal feeding practices for toddlers. Pediatric nurses should address these modifiable factors when developing nursing interventions and strategies to promote a healthy nutritional status in toddlers.

OBJECTIVES: To study the impact of the home literacy environment on children's emotional regulation skills and the mediating role of the parent-child relationship between them. METHODS: A stratified cluster sampling approach was employed to select 1 626 preschool children from five kindergartens in Nanjing. Questionnaires were used to collect detailed information on the home literacy environment, children's emotional regulation skills, and the parent-child relationship. A mediation model was established using the Process program in SPSS macro, and the significance of the mediation effect was tested using the Bootstrap method. RESULTS: The findings revealed a positive correlation between the home literacy environment and children's emotional regulation skills (r=0.217, P<0.001), as well as parent-child intimacy (r=0.065, P<0.01). Conversely, a negative correlation was found between the home literacy environment and parent-child conflict (r=-0.129, P<0.001). Additionally, parent-child conflict demonstrated a negative correlation with children's emotional regulation skills (r=-0.443, P<0.001), while parent-child intimacy exhibited a positive correlation (r=0.247, P<0.001). The home literacy environment exerted a significant direct effect on children's emotional regulation skills (ß=0.162, P<0.001), and the mediating effect of the parent-child relationship accounted for 25.54% of the total effect. CONCLUSIONS: The home literacy environment significantly influences children's emotional regulation skills, with the parent-child relationship partially mediating this relationship.

Meta-analysis of prevalence and filling rate of dental caries in preschool children in China.

OBJECTIVES: This study aims to understand the prevalence and treatment status of dental caries in preschool children aged 3-5 years in China among the past five years. METHODS: Databases including CNKI, WanFang data, VIP, MEDLINE, EMBASE were systematically searched for the epidemiological literature of dental caries in preschool children in China from 2017 to 2022 for Meta-analysis. Subgroup analysis was carried out by sex, age, geographical region, ethnology, and residence. RESULTS: The Meta-analysis enrolled 27 literatures, including 72 788 preschool children; of which, 38 344 children had dental caries. The merged prevalence of dental caries in preschool children was 59.3% (95%CI: 54.6%-63.9%), and the merged filling rate of caries was 5.7% (95%CI: 2.5%-8.8%). In the subgroup analysis, the merged prevalence rates of caries in children aged 3, 4, and 5 years were 46.9% (95%CI: 42.5%-51.4%), 59.0% (95%CI: 55.1%-62.8%), and 67.3% (95%CI: 62.5%-72.2%), respectively, and the difference was significant. In addition, significant differences were found among different regions. The merged prevalence of dental caries in preschool children was the highest in northwest China (68.6%, 95%CI: 55.5%-81.8%) and the lowest in central China (49.1%, 95%CI: 47.3%-51.0%). The merged prevalence of dental caries was not significantly different among preschool children of different genders, ethnicities, and residence. CONCLUSIONS: The prevalence of dental caries in preschool children aged 3-5 years in China is high and continuously increases. The oral health of preschool children should be comprehensively strengthened, and a three-level strategy should be implemented to prevent diseases.
