Distribution and correlation of refractive parameters in children with different corneal curvatures in southeast China

AIM

To analyze the distribution of refractive status in school-age children with different corneal curvatures (CC) and the correlation between CC and refractive status.

METHODS

A total of 2214 school-aged children of grade 4 in Hangzhou who were screened for school myopia were included. Uncorrected distance visual acuity (UCDVA), non-cycloplegic refraction, axial length (AL), horizontal and vertical corneal curvature (K1, K2) were measured and spherical equivalent (SE), corneal curvature radius (CCR) and axial length/corneal radius of curvature ratio (AL/CR) were calculated. UCDVA<5.0 and SE≤-0.50 D were classified as school-screening myopia. According to the different CCRs, the patients were divided into the lower corneal curvature (LCC) group (CCR≥7.92) and the higher corneal curvature (HCC) group (CCR<7.92). Each group was further divided into the normal AL subgroup and the long AL subgroup. The refractive parameters were compared to identify any differences between the two groups.

RESULTS

Both SE and AL were greater in the LCC group (P=0.013, P<0.001). The prevalence of myopia was 38% in the LCC group and 44% in the HCC group (P<0.001). The proportion of children without screening myopia was higher in the LCC group (62%) than in the HCC group (56%). Among these children without screening myopia, the proportion of long AL in the LCC group (24%) was significantly higher than that in the HCC group (0.012%; P<0.001). The change of SE in the LCC group was less affected by the increase of AL than that in the HCC group.

CONCLUSION

School-aged children in the LCC group have a lower incidence of screening myopia and longer AL. Low CC can mask SE reduction and AL growth to some extent, and the change of AL growth change more in children with low CC than high CC. Before the onset of myopia, its growth rate is even faster than that after the onset of myopia.

Decreased vitamin D bio-availability with altered DNA methylation of its metabolism genes in association with the metabolic disorders among the school-aged children with degree I, II, and III obesity

Obesity is strongly associated with disturbances of vitamin D (VD) metabolites in the animal models. However, the related epidemiological evidence is still controversial, especially the different degrees of obesity children. Hence, in this present representative case-control study, 106 obesity school-age children aged 7-12 years were included and divided into different subgroups as degree I (the age- and sex-specific BMI≥95th percentile, n=45), II (BMI ≥120% percentile, n=34) and III (BMI ≥140% percentile, n=27) obesity groups across the ranges of body mass index (BMI). While the age- and sex-matched subjects without obesity were as the control group. Notably, it was significantly different of body composition, anthropological and clinical characteristics among the above four subgroups with the dose-response relationships (P<.05). Moreover, comparing with the control group, the serum VD concentrations were higher, VD metabolites like 25(OH)D, 25(OH)D3 and 1,25(OH)2D, and related hydroxylases as CYP27A1, CYP2R1 and CYP27B1 were lower in the degree I, II, and III obesity subgroups (P<.05), which were more disorder with the anthropological and clinical characteristics as the obesity was worsen in a BMI-independent manner (P<.05). However, there was a significant increase of CYP27B1 in the degree III obesity group than those in the degree I and II obesity subgroups. Furthermore, the methylation patterns on the genome-wide (Methylation/Hydroxymethylation) and VD metabolism genes (CYP27A1, CYP2R1 and CYP27B1) were negatively correlated with the worse obesity and their related expressions (P<.05). In summary, these results indicated that obesity could affect the homeostasis of VD metabolism related genes such as CYP27A1, CYP2R1, CYP27B1 and etc through abnormal DNA methylation, resulting in the disorders of VD related metabolites to decrease VD bio-availability with the BMI-independent manner. In turn, the lower levels of VD metabolites would affect the liver function to exacerbate the progression of obesity, as the Degree II and III obesity subgroups.

Insulin resistance, C-reactive protein, diastolic to systolic blood pressure ratio and epicardial fat are related to sedentary time, and inversely related to physical activity in school-aged children

Background

Physical activity (PA) is beneficial for the overall health. Objectives are: (1) To compare metabolic (MRM) and cardiovascular-risk-markers (CRM) in children according to their PA-level; (2) to explore the associations of MRM and CRM with PA and sedentary time (ST); and (3) to identify the associations between MRM and CRM in less (LA) and more active (MA) children.

Methods

A total of 238 apparently healthy school-aged children were enrolled (132 boys/106 girls; 9.1 ± 1.8 years) and body mass index standard deviation score (BMI SDS) and blood pressure were assessed. Fasting venous blood sampling was performed to assess insulin resistance (HOMA-IR) and high-sensitivity-C-reactive protein (hsCRP). Epicardial fat, interventricular septal and left ventricular posterior wall thicknesses were assessed by high-resolution ultrasonography. PA and ST were assessed by enKid-questionnaire. Children were classified based on enKid-score as being LA and MA (below and above 50th percentile for PA).

Results

MA-children had lower values for: BMI SDS, diastolic-to-systolic blood pressure ratio, HOMA-IR and hsCRP (7.02 to 61.5% lower, p = 0.040 to p < 0.0001) compared to LA-children. MRM and CRM were positively associated with ST (p = 0.003 to p < 0.001), and negatively associated with PA (p = 0.044 to p < 0.001). Finally, MRM were positively associated with CRM (p = 0.008 to p < 0.0001). Interestingly, the latter associations were observed in LA-children but were not present in MA-children.

Conclusion

More PA is associated with better cardio-metabolic profile in school-aged children. PA seems to modulate the associations between MRM and CRM, thus reinforcing the idea that fostering PA in children may lower the risk for development of a cardio-metabolic disease.

Smiling synchronization predicts interaction enjoyment in peer dyads of autistic and neurotypical youth

LAY ABSTRACT

For autistic and neurotypical youth, having positive social interactions with other youth is an important part of well-being. Other researchers have found that one factor that can make people feel like social interactions have gone well is synchronization. Synchronization happens when peoples' body movements and facial expressions align while they're interacting. We focus on smiling synchronization here because other studies have found that when neurotypical individuals synchronize their smiles more in a social interaction, they say they enjoy that social interaction more. However, no studies have directly tested whether smiling synchrony influences social interaction enjoyment in autistic and neurotypical youth. We measured smiling synchrony in pairs of interacting autistic and neurotypical youth who were meeting each other for the first time. Some pairs were autistic youth interacting with other autistic youth (autistic with autistic participant pairs), some pairs were autistic youth interacting with neurotypical youth (autistic with neurotypical participant pairs), and other pairs were neurotypical youth interacting with neurotypical youth (neurotypical with neurotypical participant pairs). We found that autistic with neurotypical participant pairs had lower smiling synchrony than neurotypical with neurotypical participant pairs. Youth who were in dyads that had more smiling synchrony said they enjoyed interacting with their partner more and that they wanted to interact with their partner again. Our research shows that smiling synchrony is one part of interactions between autistic and neurotypical youth that influences how well youth say the interaction went. Identifying natural opportunities for autistic and neurotypical youth to share positive feelings could be one way to promote positive social interactions between autistic and neurotypical youth.

Syllable- and word-based measures of stuttering in speech samples of Turkish-speaking school-aged children

Linguistic factors influence the likelihood of occurrence of stuttering instances on a certain word within an utterance. However, studies on the relationship between stuttering instances and linguistic factors of Turkish-speaking individuals are scarce. This study aimed to determine the syllable- and word-based measures of stuttering speech samples of Turkish-speaking school-aged children who stutter. Stuttering-like disfluencies (SLDs) and lexical categories were identified after transcription of 61 children's spontaneous speech samples (age range = 6-16). Syllable-, word- and utterance-level measures were employed. Syllable-based and word-based stuttering frequency findings were significantly different (p < .001); SLDs were more likely to occur at the utterance-initial (p < .001) and word-initial (p < .001) positions; content words were more likely to be stuttered and, there was a relation between the occurrence of SLDs and utterance length (p = .001). Since there is great variability between word-based and syllable-based measures, and SLDs tend to occur at word onsets, using word-based measures in Turkish would provide a measure of stuttering frequency that is comparable to the literature. Moreover, findings support that phrases requiring greater demands on utterance planning increase the possibility of occurrence of stuttering instances.

Academic achievement at ages 11 and 16 in children born with congenital anomalies in England: A multi-registry linked cohort study

BACKGROUND

Children born with major congenital anomalies (CAs) have lower academic achievement compared with their peers, but the existing evidence is restricted to a number of specific CAs.

OBJECTIVES

To investigate academic outcomes at ages 11 and 16 in children with major isolated structural CAs and children with Down or Turner syndromes.

METHODS

This population-based cohort study linked data on approximately 11,000 school-aged children born with major CAs in 1994-2004 registered by four regional CA registries in England with education data from the National Pupil Database (NPD). The comparison group was a random sample of children without major CAs from the background population recorded in the NPD that were frequency matched (5:1) to children with CAs by birth year, sex and geographical area.

RESULTS

Overall, 71.9%, 73.0% and 80.9% of children with isolated structural CAs achieved the expected attainment level at age 11 compared to 78.3%, 80.6% and 86.7% of the comparison group in English language, Mathematics and Science, respectively. Children with nervous system CAs as a whole had the lowest proportion who achieved the expected attainment at age 11. At age 16, 46.9% of children with CAs achieved the expected level compared to 52.5% of their peers. Major CAs were associated with being up to 9% (95% confidence interval [CI] 8%, 11%) and 12% (95% CI 9%, 14%) less likely to achieve expected levels at ages 11 and 16, respectively, after adjustment for socioeconomic deprivation.

CONCLUSIONS

Although many children with isolated CAs achieved the expected academic level at ages 11 and 16, they were at higher risk of underachievement compared to their peers. These stark yet cautiously encouraging results are important for counselling parents of children with specific CAs and also highlight the possible need for special education support to reduce potential academic difficulties.

Analysis of the nutritional composition and organization of school meals in the province of Kadiogo in Burkina Faso: challenges and prospects

Background

In the face of food shortages and precariousness, school meals are an effective means of encouraging pupils to attend and stay in school, and of combating nutritional deficiencies. Unfortunately, there are bottlenecks to be identified and resolved.

Objective

Analyzing the composition of meals served to school-age children in primary schools in the province of Kadiogo, while assessing the opinion of school staff on these meals (Burkina Faso).

Methods

A descriptive cross-sectional survey about school meals was carried out during the period from April to May 2019 among school stakeholders in primary schools in five (05) municipalities of the province of Kadiogo.

Results

Insufficient quantity and quality of rations served were recorded in primary schools. The endogenous initiative canteens represented 46.4% of the registered canteens. The promotion of Health-Hygiene-Nutrition (H-H-N) activities in schools encountered difficulties in covering the sanitary needs of school-aged children because unavailability of socio-sanitary infrastructures. School meals consisted of starchy foods and legumes in rural schools and more diversified meals consisting of fruits and vegetables as well as meat and fish in urban schools. In rural municipalities, school meals were insufficient in quantity and quality, while in the urban municipality, macronutrient intakes were in excess with micronutrient intakes largely deficient.

Conclusion

Despite the shortcomings, school officials specified that school meals cover lunch rations, increase school enrolment, and improve school-aged children' learning capacity.

Randomized Field Trial to Assess the Safety and Efficacy of Dihydroartemisinin-Piperaquine for Seasonal Malaria Chemoprevention in School-Aged Children in Bandiagara, Mali

BACKGROUND

Owing to the increased cases of malaria in older children, the World Health Organization has recently recommended extending seasonal malaria chemoprevention (SMC) to children >5 years of age and using other effective drugs for malaria. In this study, we report the safety and efficacy of dihydroartemisinin-piperaquine (DHA-PQ) for SMC in school-aged children in Mali.

METHOD

This randomized, controlled trial included 345 participants aged 6-15 years randomized to receive DHA-PQ, sulfadoxine-pyrimethamine plus amodiaquine (SP-AQ), or no chemoprevention (albendazole) at a 1:1:1 ratio. Four rounds of SMC were conducted from September to December 2021. The participants were assessed 7 days after each round for safety and efficacy of the interventions.

RESULTS

Abdominal pain (11.8% vs 29.2%), headache (11.2% vs 19.2%), and vomiting (5.7% vs 15.2%) were frequently reported in the DHA-PQ and SP-AQ arms. On Day 120 of follow up, the incidence of clinical malaria was 0.01 episodes/person-month in the DHA-PQ and SP-AQ arms and 0.17 episodes/person-month in the control arm (P < .0001). Gametocytes were detected in 37 participants in all arms.

CONCLUSIONS

Children in DHA-PQ arm reported less adverse events compared to the SP-AQ arm. Both drugs were effective against clinical malaria and infection.

Studies assessing domains pertaining to structural language in autism vary in reporting practices and approaches to assessment: A systematic review

LAY ABSTRACT

Under the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), language impairment can co-occur with autism. It is not yet clear how research defines, reports, and characterizes structural language abilities of autistic individuals eligible for school-based special education services (aged 3-21 years) in the United States. In the United States, students typically must be formally diagnosed to be eligible for services and supports. However, the quality of diagnosis is only as good as the research evidence on which diagnosis depends. To evaluate evidence quality, we examined how studies of school-aged autistic individuals report assessments of language ability. This systematic review included 57 studies using English language age-referenced assessments used to measure structural language. Findings showed many differences across studies in how language abilities were measured and reported. Also, none of the studies fully reported the variables relevant to characterizing language impairment. Outcomes were similar across versions of the Diagnostic and Statistical Manual of Mental Disorders. Findings indicate that researchers and clinicians should pay attention to reporting diagnostic and grouping criteria. Carefully interpreting research evidence is critical for ensuring that diagnostic criteria and supports are representative of and accessible to autistic individuals and relevant parties.

Testing the Effects of Two Field-to-Fork Programs on the Nutritional Outcomes of Elementary School Students From Diverse and Lower-Income Communities

The purpose of this quasi-experimental study was to evaluate the effects of two farm-to-school programs, specifically the Field-to-Fork Multi-visit Program (N  =  264) and the Field-to-Fork After-school Club (N  =  56), on nutritional outcomes of elementary school students (third to fifth grade) from urban, diverse, and lower-income communities. Data were collected via self-report surveys measuring: (a) knowledge of recommendations for daily fruit and vegetable intake; (b) fruit and vegetable consumption; (c) knowledge of cooking a healthy recipe using vegetables; and (d) desire for farm fresh foods at school. Statistical analyses included McNemar's and Wilcoxon signed rank tests. The proportion of students knowing how to cook a vegetable rich recipe increased with both programs (Multi-visit Program p < .001; After-school Club p  =  .002). Vegetable consumption increased with the After-school Club (p  =  .002). Farm-to-school programming can increase knowledge of cooking vegetable rich recipes and vegetable intake among elementary school students from diverse, urban, and lower-income communities.

Evaluation of the relationship between sleep bruxism and sleeping habits in school-aged children

OBJECTIVE

To evaluate the relationship between sleep habits and sleep bruxism (SB) in schoolaged children.

METHODS

Survey data were collected from the parents of 500 children (267 males and 233 females; age range 6-12 years). The American Academy of Sleep Medicine diagnostic criteria were used to evaluate SB. A Children's Sleep Habits Questionnaire was conducted to determine sleep habits. The chi-square test was used for statistical evaluation.

RESULTS

SB was observed in 160 children (32%). SB awareness was 5.4%. The presence of SB in other family members, mothers' education ≤8 years, and income below minimum wage were found as family risk factors. The presence of sleep disorders was 61.4% and observed to be statistically higher in those with SB.

CONCLUSION

SB is a prevalent disorder that might be associated with sleep disorders. The parents of children with SB had inadequate knowledge and awareness pertaining to SB.

A Cross-Sectional Analysis of Health Behavior in School-Aged Children: The Qassim Study

Background Childhood obesity is a worldwide public health epidemic. Sedentary lifestyles and unhealthy dietary patterns increased the rates of overweight and obesity among children. This study aimed to (1) estimate healthy behaviors (including dietary patterns and physical activity) and (2) determine the prevalence of overweight and obesity among Saudi school-aged children in the Qassim region, Saudi Arabia. Methods A population-based cross-sectional study was conducted among Saudi schoolchildren aged between five and 16 years old. The study group consisted of 339 children including 237 males and 102 females. Data were collected using a questionnaire based on the Health Behavior in School-Aged Children (HBSC) survey. Body mass index (BMI) for age and gender was computed for each child using the AnthroPlus 2007 software (World Health Organization {WHO}, Geneva, Switzerland). Statistical Package for Social Sciences (SPSS) version 23.0 (IBM SPSS Statistics, Armonk, NY) was used for data analyses. Results The prevalence of overweight and obesity among Saudi children was 46 (13.6%) and 81 (23.9%), respectively. Males consumed more soft drinks and energy drinks, whereas females consumed more fruit juice. As children grew older, the consumption of unhealthy food and beverages increased. Males engaged in more daily physical activity compared to females. Conclusion Saudi schoolchildren (aged 5-16 years) demonstrated significant gender-specific variations in dietary patterns and levels of physical activity. A significant proportion of Saudi children were overweight or obese. The study highlighted the complex relationship between age, school class, gender, and health behaviors among Saudi school-aged children. Policymakers and parents could benefit from the understanding of such complex relationships to promote healthy behaviors among school-aged children.

Is Mindful Parenting Associated with School-Aged Children's Meta-Mood? Exploring the Role of Children's Mindfulness

Previous studies have shown that mindful parenting is associated with children's emotional development. The current study explored the association between mindful parenting and school-aged children's meta-mood, with children's mindfulness as a potential mediator. A total of 375 valid parent-child pairs were recruited from two primary schools in China. Parents' mindful parenting and children's meta-mood were measured at baseline. Five months later, children completed measures of mindfulness and meta-mood. The results indicated that mindful parenting directly and indirectly predicted school-aged children's meta-mood, with the latter mediated by children's mindfulness. This study contributes to the field of emotional development in school-aged children. The results of this study imply that intervention in mindful parenting may foster school-aged children's healthy emotional development through children's mindfulness.

Temporal Trends in Cardiovascular Health Status Among Chinese School-Aged Children From 1989 to 2018: Multiwave Cross-Sectional Analysis

BACKGROUND

Despite the release of updated metrics for Life's Essential 8 (LE8), key indicators for assessing cardiovascular health (CVH) status, there is currently no report on their distribution among Chinese children.

OBJECTIVE

This study aimed to assess the nationwide distribution of CVH in Chinese school-aged children using LE8 scores and analyze temporal changes in these scores over time.

METHODS

Participants aged 7 to 19 years from 11 waves (between 1989 and 2018) of the China Health and Nutrition Survey were included in this study. LE8 components were grouped into 2 domains of health behaviors (diet, physical activity, nicotine exposure, sleep) and health factors (BMI, blood lipids, blood glucose, blood pressure). Scores of overall CVH and each LE8 metric were calculated individually. Temporal changes were assessed with joint point regression models by rural and urban living residence. The causal relationships between health behaviors and health factors that changed the most over time were built with cross-lagged panel models.

RESULTS

A total of 21,921 participants, 52.6% (n=11,537) of whom were male, who had data for at least 4 CVH components were included in the analysis. The mean age was 13 (SD 3.6) years. The overall CVH score remained stable in most regions, with the lowest found in Shandong from East China, which had a mean between 67 (SD 10.9) and 67.2 (SD 12.4). In contrast, the highest score was found in Guizhou from Southwest China, with a mean between 71.4 (SD 10.8) and 74.3 (SD 10.3). In rural areas, the diet score decreased significantly from 1997 onward with a speed of 0.18 (95% CI: 0.15-0.21; P<.001) per year, and the BMI score decreased significantly from 2005 onward with a speed of 0.56 (95% CI 0.44-0.68; P<.001) per year. In urban areas, the diet score decreased from 1994 onward with a speed of 0.03 (95% CI: 0.001-0.07; P=.04) per year, and the BMI score decreased from 2002 onward with a speed of 0.63 (95% CI 0.47-0.79; P<.001) per year. The sleep score dropped constantly in both urban and rural areas, with a speed of 0.69 (95% CI 0.58-0.80; P<.001) and 0.69 (95% CI: 0.52-0.86; P<.001) per year, respectively. A decline in the diet score led to a decline in the BMI score with a coefficient of 0.190 (95% CI 0.030-0.351; P=.02), while a decline in the BMI score led to a decline in sleep health with a coefficient of 0.089 (95% CI 0.010-0.168; P=.03).

CONCLUSIONS

Chinese school-aged children and adolescents were generally of moderate CVH status, but mutual influences existed between CVH metrics. Dietary interventions should be prioritized for promoting overall CVH in the future.

Younger age, higher father education level, and healthy lifestyle behaviors are associated with higher adherence to the Mediterranean diet in school-aged children

OBJECTIVES

This study aimed to assess adherence to the Mediterranean Diet (MDiet) in school-aged children in Turkey and explore the associated factors with high adherence to the MDiet.

METHOD

This cross-sectional was conducted with 2693 school-aged children. Sociodemographic, dietary, and lifestyle data were collected using a questionnaire. Mediterranean Diet Quality Index (KIDMED) was used to evaluate adherence to the MDiet. Body weight, height, neck, waist, and hip circumference were measured. Dietary intake was assessed with a 24-h food consumption record.

RESULTS

Of the 2693 children, 29.5% had high, 53.9% had moderate, and 16.6% had low adherence to the MDiet. Primary school children had significantly higher adherence to the diet than secondary school children. Adherence to the MDiet was higher in children whose fathers were university graduates. There were no significant differences in sex, body mass index (BMI), or anthropometric measurements according to MDiet adherence. The high adherence group had a significantly higher intake of protein, fiber, vitamins C, B1, B6, B2, folate, polyunsaturated fatty acids, zinc, potassium, and calcium, but lower carbohydrate intake compared with the low/moderate adherence group. Higher adherence to the MDiet was associated with adequate sleep duration (≥9 to <12 h) (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.24-2.78), whereas poor/moderate adherence was associated with age (OR, 0.80; 95% CI, 0.73-0.87) and screen time (OR, 0.50; 95% CI, 0.40-0.63). Children who reported engaging in regular physical activity were more likely to have higher MDiet adherence (OR, 1.46; 95% CI, 1.16-1.85).

CONCLUSION

The results of this study showed that >50% of the children presented moderate MDiet adherence. Younger age, adequate sleep duration, engaging in regular physical activity, less screen time, and higher education level of fathers were associated with higher adherence to the diet.

Effects of public-private partnership on diet-related obesity risk factors among school-aged children: A systematic literature review

Background: Childhood obesity is a major public health challenge. Public-private partnerships (PPPs) have been proposed as a solution; however, valid concerns exist as to whether commercial interest can be balanced with public health goals. Aims: This study describes the effects of interventions carried out through PPPs on diet-related obesity risk factors, namely fruit and vegetable (F&V), sugar-sweetened beverage (SSB), and energy-dense food consumption, among school-aged children. Methods: A systematic literature review was conducted from January 1990 to December 2021 across three databases. Out of the 276 articles initially identified, 8 were included. Data were extracted from each article on study characteristics, partners involved, partnership descriptions, and partnership outcomes. A descriptive analysis included frequency counts for specific study attributes. Results: All studies took place in the United States and were published between 2010 and 2017. Most were cohort studies (75%) and involved structured, healthy lifestyle interventions (75%). Nearly all interventions included components targeting F&V consumption (88%), followed by energy-dense food consumption (50%), and SSB consumption (38%). Business sector partners were largely food producers, food retailers, and private healthcare providers; however, few studies provided details on their partnering arrangements. No studies reported harmful changes in diet-related obesity risk factors. Conclusion: Collaboration across sectors is needed to address drivers of obesity where children live, learn, and play. The small sample size and heterogeneity in this review prohibits definitive conclusions pertaining to the effect of PPPs on childhood obesity. Future research efforts are needed to develop a taxonomy for better classifying and examining PPPs.

Myopic progression in school-aged children with moderate intermittent exotropia

Objective

It is still controversial whether intermittent exotropia (IXT) affects myopic progression during the critical period of visual development. This study retrospectively analyzed the long-term myopic changes and the impact of IXT surgery on myopic progression in school-aged children with moderate IXT.

Methods

The medical records of 65 children from 5 to 13 years old with or without IXT between 2015 and 2021 were retrospectively reviewed. Patients whose spherical equivalent refraction (SER) were less than -3.00 diopter (D) were included and divided into three groups: IXT surgery group (Group A), which comprised 22 IXT patients who received IXT surgery, IXT observation group (Group B), which comprises 19 IXT patients who only received long-term observational follow-up; and normal control group (Group C), which comprised 24 normal controls without IXT. The main outcome measurement was the rate of myopic progression, which was defined as the mean myopic shift in SER per year.

Results

The 3- and 5-years long-term follow-up rates of myopic progression were -0.47 ± 0.28 D per year and -0.48 ± 0.23 D per year respectively in Group B, and those were significantly slower than that in Group C (-0.73 ± 0.32 D per year and -0.76 ± 0.19 D per year respectively). However, there was no significant difference in the rate of myopic progression between Group A and B or between Group A and C.

Conclusion

Moderate IXT may have lower rate of myopic progression in school-aged children. Whether IXT surgery influence the rate of myopic progression still needs further study.

Advances in myopia prevention strategies for school-aged children: a comprehensive review

Myopia has significantly risen in East and Southeast Asia, and the pathological outcomes of this condition, such as myopic maculopathy and optic neuropathy linked to high myopia, have emerged as leading causes of irreversible vision loss. Addressing this issue requires strategies to reduce myopia prevalence and prevent progression to high myopia. Encouraging outdoor activities for schoolchildren and reducing near-work and screen time can effectively prevent myopia development, offering a safe intervention that promotes healthier habits. Several clinical approaches can be employed to decelerate myopia progression, such as administering low-dose atropine eye drops (0.05%), utilizing orthokeratology lenses, implementing soft contact lenses equipped with myopia control features, and incorporating spectacle lenses with aspherical lenslets. When choosing an appropriate strategy, factors such as age, ethnicity, and the rate of myopia progression should be considered. However, some treatments may encounter obstacles such as adverse side effects, high costs, complex procedures, or limited effectiveness. Presently, low-dose atropine (0.05%), soft contact lenses with myopia control features, and orthokeratology lenses appear as promising options for managing myopia. The measures mentioned above are not necessarily mutually exclusive, and researchers are increasingly exploring their combined effects. By advocating for a personalized approach based on individual risk factors and the unique needs of each child, this review aims to contribute to the development of targeted and effective myopia prevention strategies, thereby minimizing the impact of myopia and its related complications among school-aged children in affected regions.

Feature selection and association rule learning identify risk factors of malnutrition among Ethiopian schoolchildren

Introduction

Previous studies have sought to identify risk factors for malnutrition in populations of schoolchildren, depending on traditional logistic regression methods. However, holistic machine learning (ML) approaches are emerging that may provide a more comprehensive analysis of risk factors.

Methods

This study employed feature selection and association rule learning ML methods in conjunction with logistic regression on epidemiological survey data from 1,036 Ethiopian school children. Our first analysis used the entire dataset and then we reran this analysis on age, residence, and sex population subsets.

Results

Both logistic regression and ML methods identified older childhood age as a significant risk factor, while females and vaccinated individuals showed reduced odds of stunting. Our machine learning analyses provided additional insights into the data, as feature selection identified that age, school latrine cleanliness, large family size, and nail trimming habits were significant risk factors for stunting, underweight, and thinness. Association rule learning revealed an association between co-occurring hygiene and socio-economical variables with malnutrition that was otherwise missed using traditional statistical methods.

Discussion

Our analysis supports the benefit of integrating feature selection methods, association rules learning techniques, and logistic regression to identify comprehensive risk factors associated with malnutrition in young children.

Bilingual Children Shift and Relax Second-Language Phoneme Categorization in Response to Accented L2 and Native L1 Speech Exposure

Listeners adjust their perception to match that of presented speech through shifting and relaxation of categorical boundaries. This allows for processing of speech variation, but may be detrimental to processing efficiency. Bilingual children are exposed to many types of speech in their linguistic environment, including native and non-native speech. This study examined how first language (L1) Spanish/second language (L2) English bilingual children shifted and relaxed phoneme categorization along the cue of voice onset time (VOT) during English speech processing after three types of language exposure: native English exposure, native Spanish exposure, and Spanish-accented English exposure. After exposure to Spanish-accented English speech, bilingual children shifted categorical boundaries in the direction of native English speech boundaries. After exposure to native Spanish speech, children shifted to a smaller extent in the same direction and relaxed boundaries leading to weaker differentiation between categories. These results suggest that prior exposure can affect processing of a second language in bilingual children, but different mechanisms are used when adapting to different types of speech variation.

Do You See What I See? Emotion Recognition Competencies in Sexually Abused School-Aged Children and Non-Abused Children

Child sexual abuse (CSA) is a worldwide phenomenon that has been linked to deleterious consequences. Adverse life events, such as sexual abuse, can compromise the development of emotional competencies, an important dimension of children's psychosocial development. This study aimed at evaluating emotion recognition competencies in sexually abused and non-abused children. The sample consisted of 97 sexually abused children (65 girls) and 78 non-abused children (56 girls) aged between 6 and 12 years. They were recruited in specialized intervention centers and elementary schools from the Montreal area. Recognition of joy, anger, fear, sadness, and neutral expressions was assessed using the Developmental Emotional Faces Stimulus Set (DEFSS; Meuwissen et al., 2017). Results of an ANCOVA revealed that the total scores of emotion recognition were significantly lower for victims of SA (M = 18.12, SE = 0.33) relative to non-abused children (M = 19.36, SE = 0.37), F(1,170) = 5.70, p < .05. Analyses performed on specific expressions yielded lower scores for the recognition of anger, F(1, 170) = 6.12, p = .014, partial η2 = .03, and joy, F(1, 170) = 8.04, p =.005, partial η2 = .04. Our findings highlight the importance of assessing emotion recognition competencies to improve intervention programs provided to sexually abused children and prevent the development of severe psychosocial problems.

The Recover Study: A Cross-Sectional Examination of the Relationship Between Ontario Parents' Resilience and COVID-19-Related Stressors

Resilience, or the ability to bounce back despite facing adversities, may influence parents' abilities to handle the multitude of parent-specific COVID-19-related challenges that have faced them. This cross-sectional study examined (1) the relationship between parents' resilience and their COVID-19-related family stressors; (2) parents' perceptions of their greatest stressors throughout the pandemic; and (3) non-school-related challenges and their resultant impact on parents' and children's resilience. Via an online survey, data was collected from 63 parents (Mage = 37.09; 82.54% female). A significant relationship was found between parents' resilience and both their COVID-19-related stressors and family stressors. Parents described stressors challenging their resilience, including impacts on their mental health, managing occupational and educational responsibilities, social isolation, and economic setbacks, while also noting the impacts of social isolation, missing extracurricular activities, and lacking routines for their children. Overall, Ontario parents high in resilience are likely better positioned to adapt to pandemic-related stressors.

Associations of sport participation with subjective well-being: a study consisting of a sample of Chinese school-attending students

Purpose

Past studies have illustrated that the impact of sports participation on school-attending students' well-being plays a significant role in the life course of adolescence, which is a golden period for developing sound psychological qualities. However, the relationship between sports participation and subjective well-being is not clear, particularly in Chinese primary and middle schools. Therefore, the current study was aimed to explore the relationship between sports participation and subjective well-being in elementary and middle schools in China.

Method

All involved children and adolescents were asked to conduct a self-report of their sociodemographic factors (e.g., sex, grade, and age), independence, and outcomes. The survey involved a two-stage sampling design (district school). Besides, in order to examine the relationship between participation in sports and subjective well-being, a self-report questionnaire was used. Logistic regression with 95% confidence interval and odds ratios (ORs), was conducted to investigate the relationship between sports participation and subjective well-being.

Results

A total of 67,281 participants in total provided complete data for the final analysis of the current study. The percentage of boys and girls was 51.9% and 48.1%, namely. The current study found that compared with children who never participate in sports, those children who participated sports in 1-3 times a month, 1-2 times a week, and 3 times a week and above were more likely to enjoy better well-being. Compared with children who never participate in sports, those children who in every grade participated sports in 1-3 times a month, 1-2 times a week, and 3 times a week and above were more likely to achieve better well-being.

Conclusion

Our current study offered the positive effect of sports participation on children and adolescents' subjective well-being. For schools and governments, further studies are needed to focus on sports participation and positive feedback on adolescents' mental health, and the three parties' endeavors should be intervened.

The Effects of Physical Activity on Academic Performance in School-Aged Children: A Systematic Review

Schools offer a unique environment to influence children's physical activity (PA) levels positively. This study aims to systematically review the evidence surrounding how PA affects academic performance by analysing how the frequency, intensity, time, and type of PA mediate academic performance outcomes. This review was conducted using the PRISMA framework. Keyword searches were conducted in Science Direct, PubMed, and SPORTDiscus. Children that were obese, typically developing, typical weight, disabled, with a developmental disability, from a low socio-economic background, or an ethnic minority were included. A total of 19 studies were included, with a total of 6788 participants, a mean age of 9.3 years (50.2% boys, and 49.8% girls). Overall, 63.2% were nondisabled, while 36.8% were diagnosed with a disability. Two authors met, reviewed papers with regard to the inclusion criteria, and agreed on outputs to be included. Evidence suggests that associations between PA and academic performance were primarily positive or nonsignificant. PA levels of 90 min plus per week were associated with improved academic performance, as was PA performed at moderate to vigorous intensity. The optimal duration of PA was 30-60 min per session, whilst various sports induced positive academic effects. Importantly, findings support that PA does not have a deleterious effect on academic performance but can enhance it.

Mild Traumatic Brain Injury and Behavior and Sleep Among 9- and 10-Year Old Children: Initial Findings From the Adolescent Brain Cognitive Development (ABCD) Study

There has been concern about the potential sequelae of mild traumatic brain injury (mTBI) in children. This study used data from the Adolescent Brain Cognitive DevelopmentSM (ABCD) study to investigate associations between mTBI and behavior and sleep in school-aged children. Generalized additive mixed models were run to examine the association between TBI and parent-reported Child Behavior Checklist and Sleep Disturbance Scale for Children scores. mTBI with or without loss of consciousness (LOC) in 9- and 10-year old children was associated with 1) higher internalizing, externalizing and total problems and 2) greater sleep disturbance scores on the CBCL. The study also demonstrated a higher incidence of mTBI with and without LOC in boys compared to girls. This study shows a statistically significant but modest association between mTBI and behavioral and sleep changes, suggesting that in a non-clinical, sociodemographically diverse community sample of school-aged children mTBI does not result in clinically significant behavioral or psychological sequelae.

Music, drama, and social development in Portuguese children

Introduction

Social competence plays a fundamental role in children's development, and in their functioning at school and in life. Social skills, as learned behaviors that allow children to positively interact with others, are important for success in both academic and peer-group settings. Children's participation in collective music and other arts education has been associated with the development of social skills. However, different measures and diverse programs adopted in various studies make it difficult to contrast study findings. Additionally, research with children from low-income families remains scarce. The aim of this study was to examine the role of music and drama education programs in primary schools on the development of social skills of Portuguese children from disadvantaged communities. Both programs were carefully designed with performing, creating, and listening activities, and were delivered by specialist and experienced teachers/performers, who used active and participatory teaching strategies.

Methods

In our longitudinal design with pre- and post-evaluations, we used the Social Skills Rating System or SSRS-Teacher Form, adapted for the Portuguese population. Classroom teachers rated their students' social skills on a 3-point scale in three domains: Social skills (Cooperation, Assertion, Self-control), Behavioral problems (Externalizing problems, Internalizing problems, Hyperactivity) and, on a 5-point scale, Academic competence.

Results and Discussion

Our findings suggest that participation in music and drama programs during one school year improved children's assertion and self-control, and cooperation in the drama group. Participation in the music and drama programs also appeared to serve as a protective factor by reducing externalizing, internalizing and behavioral problems. These findings are discussed in light of previous studies along with limitations and directions for future research.

Exploring variations in gait patterns and joint motion characteristics in school-aged children across different walking speeds: a comprehensive motion analysis study

This study aimed to investigate differences in gait patterns among individuals with different walking speeds and identify the range of motion (ROM) and angular velocity for various joints during gait. Forty-five schoolchildren were randomly selected for this study. To capture their walking patterns, two FDR-AX700 4K HDR camcorders were positioned to observe the predetermined walkway. Each participant completed a 5-meter walk at various speeds, including slow, normal, and fast, while maintaining a straight stride. There were significantly higher ROM and angular velocity (p<0.05) at the hip, knee, and ankle joints across most stages of walking at a faster speed compared to slow and normal speeds. At the same time, the angular velocity was significantly higher at the hip joint during hip extension terminal stance at normal speed compared to slow and fast speeds (p<0.05, ƞ2 =0.74). Similarly, the ROM of knee flexion swing, ankle plantar flexion loading response, and ankle dorsiflexion midswing angular velocity were significantly higher during normal walking speed (p<0.05). Conversely, slow-speed walking showed significantly higher ROM at knee extension terminal swing (ƞ2=0.52) and ankle dorsiflexion terminal stance (ƞ2=0.78) (p<0.05). The results indicate that individuals with different walking speeds exhibit significant differences in gait patterns. Slower walking speeds resulted in lower gait velocity and different joint motions compared to faster walking speeds.

Factors Associated With Helicobacter Pylori Infection Among School-Aged Children From a High Prevalence Area in Vietnam

Objectives: The study aimed to identify prevalence of H. pylori infection and associated risk factors among pupils of Ho Chi Minh city (HCMC). Methods: A total of 1,476 pupils aged 6-15 years were enrolled in this cross-sectional study using multiple-stage sampling method. Infection status was assessed using stool antigen-test. A questionnaire was used to obtain socio-demographic, behavioral, and environmental factors. Logistic regression was performed to assess possible factors related to the infection. Results: Of the 1,409 children included in the analysis, 49.2% were male and 95.8% were of Kinh ethnicity. About 43.5% of parents completed college or university. The overall prevalence of H. pylori was 87.7%. Infrequency of handwashing with soap after toilet, the use of only water to clean after toilet, crowded living areas, larger family size, and younger age were independently contributing to an increased prevalence of H. pylori. Conclusion: H. pylori infection is highly prevalent in HCMC, and is associated with poor hygienic practices, crowded living areas, larger family size, and younger age. These findings highlight the importance of fecal-oral route and the attribution of crowded living conditions to the spreading of H. pylori in HCMC. Therefore, preventive programs should be set up with a focus on education of hygiene practices, and oriented to those living in crowded conditions.

Exposures to Organophosphate Esters and Respiratory Morbidity among School-Aged Children with Asthma

Organophosphate esters (OPEs) are an emerging class of chemicals used in a variety of consumer products as flame retardants, plasticizers, and additives. While prior epidemiologic studies suggest that OPEs may impact respiratory health, results remain inconclusive. We examined associations between urinary biomarkers of OPEs and symptoms of respiratory morbidity in a panel study of 147 predominantly Black school-aged children with asthma living in Baltimore City, Maryland. The study consisted of up to four seasonal, week-long, in-home visits where urine samples and self-reported asthma symptoms were collected on days 4 and 7 (n_samples = 438). We quantified concentrations of nine urinary OPE biomarkers: bis(2-chloroethyl) phosphate (BCEtp), bis(1-chloro-2-propyl) phosphate (BCPP), bis(1,3-dichloro-2-propyl) phosphate (BDCIPP), di-n-butyl phosphate (DBuP), di-benzyl phosphate (DBzP), di-o-cresylphosphate (DOCP), di-p-cresylphosphate (DPCP), di-(2-propylheptyl) phthalate (DPHP), and 2,3,4,5-tetrabromo benzoic acid (TBBA). We estimated prevalence odds ratios (POR) of respiratory morbidity symptoms using logistic regression with generalized estimating equations to account for our repeated measure design. We assessed BDCIPP and DPHP as continuous (log₂) concentrations and dichotomized exposure of BCEtP, DBuP, and DPCP (detect vs non-detect) based on their lower detection frequencies. We adjusted models for season, visit day, age, gender, caregiver education, health insurance type, exposure to household smoking, atopy, and PM_2.5. Higher DPHP concentrations were significantly associated with odds of daytime symptoms (POR: 1.26; 95% CI: 1.04-1.53; p = 0.02) where daytime symptoms consisted of trouble breathing due to asthma, reporting bother caused by asthma, and/or limitation in activities due to asthma. DBuP detection was associated with use of rescue medication on the day of sample collection (POR: 2.36; 95% CI: 1.05-5.29; p = 0.04). We also observed several consistent, albeit non-significant (p > 0.05), positive associations for BCEtP and DPCP and respiratory morbidity measures. This is the first study to evaluate the relationship between OPE biomarkers and respiratory morbidity symptoms in children with asthma, and findings suggest that further studies are warranted to confirm whether these associations are causal.

Association between hemoglobin and elevation among school-aged children: a verification of proposed adjustments

BACKGROUND

Anemia is defined by a hemoglobin (Hb) concentration lower than normal based on cutoffs specific to age, sex, and pregnancy status. Hemoglobin increases with elevation as an adaptive response to lower blood oxygen saturation, thus, adjusting Hb concentration for elevation is necessary before applying cutoffs.

OBJECTIVE

Recent evidence among preschool-aged children (PSC) and non-pregnant reproductive-aged women (WRA) suggests that current World Health Organization (WHO) recommended Hb adjustments for elevation need updating. To confirm these findings, we examined the cross-sectional association between Hb and elevation among non-pregnant school-age children (SAC).

METHODS

Using data from 9 population-based surveys, we examined 26,518 SAC 5-14 years (54.5% female) with data on Hb and elevation (-6 to 3,834 meters, m). We used generalized linear models to assess the association between Hb and elevation under varying conditions, including controlling for inflammation-corrected iron and vitamin A deficiency. Hemoglobin adjustments for each 500 m increase in elevation were estimated for SAC and compared to existing adjustments and those estimated for PSC and WRA. We evaluated the impact of adjustments on anemia prevalence.

RESULTS

Hemoglobin concentration (g/L) was positively associated with elevation (m). The SAC elevation adjustments were consistent with those reported among PSC and WRA and suggest current recommendations may under-adjust Hb for those residing at lower elevations (<3000 m) and over-adjust Hb for those residing at higher elevations (>3000 m). Among the surveys included, proposed elevation adjustments increased anemia prevalence among SAC by 0 (Ghana, United Kingdom) to 15 (Malawi) percentage points relative to current elevation adjustments.

CONCLUSION

Results confirm that current recommended Hb adjustments for elevation may need updating, and anemia prevalence in SAC may be higher than currently estimated. Findings will inform the WHO reexamination of global guidelines on the use of Hb adjustments for anemia assessment and may result in improved identification and treatment of anemia.

Prevalence and Demographic Distribution of Hypermobility in a Random Group of School-Aged Children in Nigeria

BACKGROUND

The purpose of this study was to determine the prevalence of hypermobility in randomly selected healthy children, without previous trauma or disease process affecting the joints and whether other demographic variables (age, sex, BMI) had an impact on Beighton scores and range of motion (RoM) in children between 6 and 10 years of age.

RESULTS

286 children were included; 27.3% of them had a Beighton score ≥7/9 and 72% would be classified hypermobile if we had used a Beighton cut-off score ≥4/9. Prevalence declined with increasing age. Girls were more often hypermobile (34%) than boys (20%) and this was mainly caused by increased RoM in the knees. Positive scores of finger items of the Beighton were more common than on the other items, leading to a high prevalence of peripheral hypermobility. Localized hypermobility was only found in the fifth MCP joint. A total of 15% of the children with normal mobility reached 20 excess degrees RoM of the left and right fifth MCP. Pain was present in 12 of the 239 children but was not linked to the level of mobility.

CONCLUSION

Hypermobility is the rule in this pain-free population of children with GJH.

Situation-specific outcomes (Home Situations Questionnaire) in a randomized controlled trial of individual versus group parent training for children with Hyperkinetic Disorder/Attention-deficit Hyperactivity Disorder

OBJECTIVES

Assess (a) the variability of behaviour problems in children with Hyperkinetic Disorder/Attention-DeficitHyperactivity Disorder (HKD/ADHD) across a range of family situations and (b) the degree to which behaviour in each situation can be modified through a cognitive behavioural parent training (CBPT). Furthermore (c), compare the effectiveness of training in two different formats and (d) test the proposition that group treatment benefits behaviour in a wider range of situations than individual treatment.

METHOD

A registered multicentre randomized controlled trial comparing individual and group parent training to treatment-as-usual (TAU) for N = 237 children with HKD/ADHD. A German version of the Home Situations Questionnaire (HSQ) was employed to examine behaviour problems across a range of family situations, treatment-related changes post-treatment and at 6-month follow-up, while controlling for medication status.

RESULTS

Parents reported considerable variance in severity of behaviour problems across situations. All groups improved with time, but individual and group CBPT led to significantly greater improvement than TAU in many family situations. Results present situation-specific treatment trajectories and demonstrate somewhat greater impact of individual compared with group training in certain situations post-training and 6 months later.

CONCLUSIONS

CBPT clearly adds to TAU (with effect sizes in the small to moderate range depending on situation). Individual was somewhat more successful than group format (which did not succeed in a wider range of situations). HSQ situations reveal a differentiated picture of child behaviour and treatment results. Situation-specific assessment with an instrument like the HSQ offers promising perspectives that invite further development.

Assessing the construct validity of a theory of mind battery adapted to Tunisian school-aged children

Background

Theory of mind (ToM) refers to the ability to understand others' states of mind, desires, emotions, beliefs, and intentions to predict the content of their mental representations. Two major dimensions within ToM have been studied. The first is the type of inferred mental state, which can be cognitive or affective. The second comprises the types of processes involved according to their degree of complexity (first- and second-order false belief and advanced ToM). ToM acquisition is fundamental-a key component in the development of everyday human social interactions. ToM deficits have been reported in various neurodevelopmental disorders through various tools assessing disparate facets of social cognition. Nevertheless, Tunisian practitioners and researchers lack a linguistically and culturally appropriate psychometric tool for ToM assessment among school-aged children.

Objective

To assess the construct validity of a translated and adapted French ToM Battery for Arabic-speaking Tunisian school-aged children.

Methods

The focal ToM Battery was designed with neuropsychological and neurodevelopmental theory and composed of 10 subtests distributed evenly in three parts: Pre-conceptual, cognitive, and affective ToM. Translated and adapted to the Tunisian sociocultural context, this ToM battery was individually administered to 179 neurotypical Tunisian children (90 girls and 89 boys) aged 7-12 years.

Results

After controlling for the age effect, construct validity was empirically confirmed on two dimensions (cognitive and affective) via structural equation modeling (SEM) analysis, demonstrating that this solution has a good fit. The results confirmed that the age affected differentially the performance obtained on ToM tasks based on the two components of the battery.

Conclusion

Our findings confirm that the Tunisian version of the ToM Battery has robust construct validity for the assessment of cognitive and affective ToM in Tunisian school-aged children; hence, it could be adopted in clinical and research settings.

"Teacher, forgive me, I forgot to do it!" The impact of children's prospective memory on teachers' evaluation of academic performance

BACKGROUND

According to Munsat (1965, The concept of memory. University of Michigan), a person who makes frequent prospective memory (PM) errors is considered as having a flawed character rather than a bad memory. Given that PM completes its development only in young adulthood, this bias might occur not only within social relationships but also in school. However, little is known about the impact of this bias on academic performance.

AIMS

This study aimed to evaluate the impact of children's PM on teacher's evaluations of their academic performance (i.e., grades) and social skills.

SAMPLE

A total of 158 eight- and twelve-year-old children (48% females) participated in this study.

METHODS

A working memory (WM) updating task was used as ongoing task (OT), in which the PM task was embedded and required participants to respond whenever certain pictures appeared. Children's social skills were measured through teacher ratings, whereas grades were collected as indicators of teachers' assessment of academic performance. Children's WM span and inhibitory control were also assessed.

RESULTS

Results showed that 8- and 12-year-old children's academic performance was predicted by both PM performance and teachers' evaluations of social skills. However, social skills evaluations were not predicted by PM performance. WM span was related to grades in 8 year olds, while inhibitory control was related to PM performance in 12 year olds.

CONCLUSIONS

These outcomes highlight that children's grades are not explained only by academic performance itself but also by other personal skills. Awareness of the biases which can occur when evaluating children's academic performance can help teachers to be more objective in their assessment.

Health Behavior and Social-Emotional Health Status of School-Aged Children According to their Experience with Atopic Dermatitis Diagnosis: Based on the 12th (2019) Panel Study on Korean Children

Atopic dermatitis (AD) is a chronic inflammatory skin disease that is common in children and is increasing worldwide. This study aimed to identify differences in children's health behavior and social-emotional health status based on AD diagnosis at late school age. For this purpose, we conducted a descriptive survey using the 12th Panel Study on Korean Children data obtained in 2019. The data were analyzed using descriptive statistics, the Rao-Scott χ2 test, and a t-test using a complex sample analysis. A total of 1412 11-year-old Korean children participated in the study, of whom an estimated 8.2% were diagnosed with AD. In the children diagnosed with AD, the transition from exclusive breastfeeding to mixed feeding was later than that in children without AD (F = 5.71, p = 0.024), and the prevalence of AD in their parents was higher (F = 6.97, p = 0.014). Regarding health behaviors, the children diagnosed with AD had a higher intake frequency of protein (F = 5.41, p = 0.028) and vegetables (F = 6.09, p = 0.020). Regarding social-emotional health, subjective health status (F = 3.94, p = 0.026) and friend relationships (F = 2.95, p = 0.007) were lower in the children diagnosed with AD. These results, as preliminary data for interventions for school-aged children with AD, suggest that the difficulties of children's peer relationships should be considered and dealt with in further interventions.

Correlates of Sedentary Time Among Children and Adolescents in Ethiopia: A Cross-Sectional Study

PURPOSE

To assess the correlates of sedentary time among children and adolescents in Ethiopia.

METHODS

The study was conducted in representative samples of children and adolescents in the capital city of Ethiopia, Addis Ababa. Multivariable logistic regression models were used to determine associations of sedentary time and predictor variables.

RESULTS

The mean sedentary time was 4.61 (95% confidence interval [CI], 4.35-4.86) hours per day. Overall, the prevalence of high sedentary time (>3 h/d) was 68.2% (95% CI, 64.2-72.2). Results of multivariable logistic regression analyses showed a statistically significant association between high sedentary time and female household head (adjusted odds ratio [AOR] = 0.50; 95% CI, 0.32-0.80), literate mothers (AOR = 1.98; 95% CI, 1.26-3.11), child attending public school (AOR = 1.79; 95% CI, 1.12-2.85), children who belonged to the poor and rich household wealth tertiles compared with medium wealth tertile (AOR = 2.30; 95% CI, 1.42-3.72 and AOR = 2.04; 95% CI, 1.14-3.65, respectively), and those families that did not have adequate indoor play space for children (AOR = 0.45; 95% CI, 0.29-0.72).

CONCLUSION

The study found that time spent sedentary was high in the study area as compared with other studies of similar settings. Several modifiable factors were identified that can be targeted in interventions to reduce sedentary time in the study setting.

'It depends on who I'm with': How young people with developmental language disorder describe their experiences of language and communication in school

BACKGROUND

The risks of developmental language disorder (DLD) for both educational progress and socio-emotional development are well documented, but little is known about how children and young people with DLD experience and describe their language and communication. The need to complement experimental and quantitative studies with qualitative perspectives of the lived experience of individuals with DLD for speech and language therapists (SLT) practice has recently been foregrounded.

AIMS

To understand further the experiences of young people with DLD focusing on language and communication in a school context, and thereby contribute to the improvement of the communicative situation in school for this group. The study is guided by the following research question: How do young people diagnosed with DLD describe their experiences of language and communication in school?

METHODS & PROCEDURES

The study is based on data generated from qualitative semi-structured interviews with 23 participants diagnosed with DLD (age 13-19 years old) living in Sweden. All participants attended mainstream schools. To enable data to be collected during COVID-19 restrictions, all interviews were conducted using Zoom. Reflexive thematic analysis was used to analyse the data.

OUTCOMES & RESULTS

Four main themes related to experiences of language and communication in school were constructed from the interviews: (1) feelings of inadequacy and comparisons with others; (2) feelings of being misjudged and misunderstood; (3) the importance of feeling safe and comfortable; and (4) the significance of the social and communicative context. The results bear witness of difficult and challenging aspects related to language and communication in school, including educational, social and emotional dimensions. An important outcome of this study is how young people diagnosed with DLD describe their language and communication functioning to be dependent on both individual characteristics and abilities, as well as situational, contextual and social factors.

CONCLUSIONS & IMPLICATIONS

The results from this study show that young people with DLD can have persisting problems related to language and communication in school, including educational, social and emotional dimensions. SLT services may therefore be needed throughout the school years to ensure that students with DLD receive adequate support. In addition, support that goes beyond language abilities and targets social, contextual and emotional aspects should be considered.

WHAT THIS PAPER ADDS

What is already known on this subject Children and young people have unique knowledge about their language and communication which is instrumental for designing interventions and support strategies. Qualitative analyses of interview data have been able to identify both risk factors and protective strategies in relation to the well-being of individuals with DLD. Despite this, children and young people with DLD are rarely heard in research or clinical discussions. What this paper adds to existing knowledge In this study we listen to the voices of young people with DLD as they describe their experiences of language and communication in school. The participants describe a condition that makes them struggle to keep up with peers and puts them at risk of being misjudged by teachers, but also give examples of situations where negative consequences are hardly felt. What are the potential or actual clinical implications of this work? DLD is a complex and dynamic disorder where contextual and social factors interact with individual abilities in creating the end result. The results of the study indicate that DLD can cause persisting problems related to language and communication in school, with impact on educational, social and emotional dimensions. To counteract these effects, SLT services may be needed throughout the school years, and support that goes beyond language abilities must be considered.

Measurement of Self-regulation in Preschool and Elementary Children: A Scoping Review

AIMS

This scoping review sought to identify and characterize measurement of self-regulation in preschool and elementary aged children.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review (ScR) guidelines were applied. Databases from the fields of allied health, education, medicine, and social sciences were searched including: CINAHL, Education Database (ProQuest), Education Research Complete, EMBASE, ERIC, iNFORMIT Combined, Medline, PsychINFO, Social Sciences (ProQuest), Teacher Reference Center, and Web of Science. Articles published between 2015 and 2020 were included. Dual review was utilized at all stages and a third reviewer resolved any conflicts.

RESULTS

Sixty-seven studies were included in this review. A range of observational, self-report, teacher report, caregiver report, and observational measures of self-regulation were identified. Included studies were primarily published in education and psychology disciplines, with no studies by occupational therapists identified.

CONCLUSIONS

Although a range of measures were identified in this scoping review, the results highlight the lack of consensus regarding self-regulation measurement that occupational therapists use to design and implement therapy programs to address child emotional and behavioral needs.

The infected and the affected: A longitudinal study of the impact of the COVID-19 pandemic on schoolchildren in Florida

Objectives

To identify risk factors associated with symptoms of anxiety, depression, and obsessive-compulsive disorder (OCD) among children during the 1st year of the COVID-19 pandemic.

Methods

A longitudinal study with three cross-sectional timepoints [April 2020 (n = 273), October 2020 (n = 180), and April 2021 (n = 116)] was conducted at a K-12 public school in Florida. Infection and sero-positivity for SARS-CoV-2 was determined by molecular and serologic approaches. Adjusted odds ratios using mixed effect logistic regression models for symptom-derived indicators of anxiety, depression, and OCD in children in April 2021 are presented; past infection and seropositivity were included in the models.

Results

The prevalence of anxiety, depression, or OCD moved from 47.1, to 57.2, to 42.2% across the three timepoints during the study. By endline of the study, in April 2021, non-white children were at higher risk for depression and OCD. Risk for anxiety, depression, and OCD was associated with students who lost a family member due to COVID-19 and who were identified as at-risk in previous timepoints. Rates of SARS-CoV-2 infection and seropositivity were low and not statistically associated with assessed outcomes.

Conclusions

In situations like the COVID-19 pandemic, targeted mental health interventions and screenings are needed in children and adolescents, especially among minority children.

A Cost-Effectiveness Analysis of Pre-Exposure Prophylaxis to Avert Rabies Deaths in School-Aged Children in India

Children contribute to one-half of the total painful rabies mortalities in India. The state-of-the-art rabies mortality averting strategies need exploration for the effective implementation of pre-exposure prophylaxis (PrEP) in India. This study reports on the economic evaluation of various PrEP and post-exposure prophylaxis (PEP) strategies to avert rabies mortalities in school-aged children in India. A decision tree model has been developed for children in the age group of 5-15 years to evaluate various PrEP + PEP and PEP only regimens. The 2-site intradermal regimen administered on day zero and seven was chosen as the intervention [PrEP (I)]. ICER was calculated from the quasi-societal and quasi-health systems' perspectives for the base case analysis, along with one-way sensitivity, and scenario analyses for each regimen. The incremental DALYs averted per million population with the implementation of PrEP (I) ranged between 451 and 85,069 in 2020. The ICER was reported in the range of USD 384-352/DALY averted (non-dominant) in comparison to PEP regimens from a quasi-societal perspective. PrEP (I) is reported to be 'very cost effective' in comparison with PEP regimens from the quasi-societal and quasi-health systems' perspectives and reduce deaths by up to 89.9%. This study concludes that the PrEP (I) regimen is a cost-effective and life-saving strategy to avert painful mortalities due to rabies in school-aged children in India.

Prevalence and Subtype Distribution of Blastocystis Isolated from School-Aged Children in the Thai-Myanmar Border, Ratchaburi Province, Thailand

Blastocystis is one of the most common enteric protozoa that inhabits the intestinal tract of humans and different animals. Moreover, it has a worldwide geographic distribution. Its main mode of transmission is via the fecal-oral route. At present, 26 subtypes are widely distributed across both humans and animals. The current study aimed to determine the prevalence and subtype distribution of Blastocystis among school-aged children living on the Thai-Myanmar border, Ratchaburi province, Thailand. In total, 508 samples were collected from children at six schools. The prevalence of Blastocystis infection was amplified and sequenced in the 600 bp barcode region of the small-subunit ribosomal RNA (SSU rRNA). The overall prevalence of Blastocystis infection was 3.35% (17/508). ST3 (11/17) was the most predominant subtype, followed by ST1 (5/17) and ST2 (1/17). A phylogenetic tree was constructed based on the Tamura92+G+I model using the maximum-likelihood algorithm. Surprisingly, all sequences of the ST3-positive samples were closely correlated with the cattle-derived sequence. Meanwhile, all sequences of the Blastocystis ST1-positive samples were closely correlated with the human-derived sequence. Nevertheless, further studies should be conducted to validate the zoonotic transmission of Blastocystis. Based on our findings, personal hygiene and sanitation should be improved to promote better health in children in this area.

The Impact of Physical Activity at School on Eating Behaviour and Leisure Time of Early Adolescents

(1) Background: Diet and physical activity (PA) significantly impact health. The aim of this study was to evaluate the impact of long-term increase in organized PA level at school on the eating behaviour and leisure time of early adolescences in the period from the age of 10 to 12. (2) Methods: Children born in 2007 (n = 278) in groups with a standard (control group) and increased level of organized PA at school (4 and 10 h a week) were subjected to an anonymous follow-up survey. The questionnaire included 22 questions related to the eating behaviour and ways and frequency of leisure time PA. The study was conducted in the same groups in three assessment sessions in September 2017, 2018 and 2019. (3) Results: During the course of the study, it was shown improvement of eating behaviour in the increased PA group whereas decline in the standard PA one. The share of children with good and very good scores of eating behaviour decreased in the standard PA group from 56.89% to 54.54% and increased in the increased PA from 58.06% to 60.29%. In the increased PA group children more frequently than standard PA ate vegetables, fruits, fish, poultry meat, wholemeal bakery products, milk, dairy products and drinking tea without sugar, as well as ate breakfast. The standard PA children more frequently than increased PA ate high sugar and/or fat content food as sweets, savoury snacks and drank fizzy drinks as well as fast foods. The frequency of often undertaken leisure time PA increased in the increased PA group from 67% to 74%, while decreased in the standard PA from 58% to 52%. (4) Conclusions: Increase in organized PA at school beneficially influenced early adolescents' eating behaviour and frequency of leisure time PA during 2 years observation. It also increased early adolescents' awareness of healthy diet. Increased PA at school helps shaping healthy lifestyle among early adolescents.

A Non-Randomized Trial Investigating the Impact of Brown Rice Consumption on Gut Microbiota, Attention, and Short-Term Working Memory in Thai School-Aged Children

While dietary fiber has been shown to influence the composition of gut microbiota and cognitive function in adults, much less is known about the fiber-microbiome-cognition association in children. We profiled gut microbiota using quantitative PCR (qPCR) and evaluated cognitive function using the Corsi block-tapping test (CBT) and the psychomotor vigilance test (PVT) before, during, and after the dietary intervention of 127 school-aged children in northern Thailand. While we found that Sinlek rice (SLR) consumption did not significantly alter the abundance of gut microbiota or the cognitive performance of school-aged children, we did find age to be associated with variations in both the gut microbiota profiles and cognitive outcomes. Gammaproteobacteria was significantly lower in the control and SLR groups during the middle time points of both phases (Weeks 4 and 61), and its abundance was associated with age. Cognitive performance using CBT and PVT were also found to be age-sensitive, as older children outperformed younger children on both of these cognitive assessments. Finally, a multiple factor analysis (MFA) revealed that age and cognitive performance best explain individual variation in this study. Collectively, these findings further describe the influence of host variables on the microbial profiles and cognitive outcomes of school-aged children consuming Sinlek rice in Thailand.

Toward the upscaling of school nutrition programs in Dubai: An exploratory study

Background

School nutrition programs impact the intellectual, social, and emotional development of school children, as well as their future risk of developing Non-Communicable Diseases. While many stakeholders are involved in the development, implementation, and evaluation of school nutrition programs in Dubai, United Arab Emirates, little is known about the complementarity among those stakeholders, and the means to upscale school nutrition programs while ensuring effective, efficient, and equitable implementation. Accordingly, this study aims at exploring the perceptions of a diverse group of stakeholders, positioned at differing levels of the public health and education ecosystems in the United Arab Emirates, in relation to current guidelines and practices around the planning, implementation, and evaluation of school nutrition programs in Dubai, United Arab Emirates.

Methods

The current study relied on a qualitative design, based on semi-structured key informant interviews. A total of 29 interviews were carried out. Those interviewees included leaders and directors from different institutions, decision- and policy- makers, nutritionists and dieticians, school nurses and nurse managers, and school principals and vice principals. All stakeholders were interviewed by the research team. Data was transcribed, and then thematically analyzed using the health systems' model as an analytic framework.

Results

The thematic analysis of interview data identified five interrelated themes. The first theme relates to the limited coordination across regulatory local and federal entities, and the multiplicity of guidelines issued by the different stakeholders. The challenges around the human and financial resourcing of school nutrition programs constituted the second theme. The third theme was the weakly coordinated implementation efforts. The fourth theme was the need for better performance measurement, and the fifth theme flagged the need for improved inclusiveness for health needs and cultural preferences of the diverse student body in Dubai (given that there are citizens from more than 200 nationalities co-existing in Dubai).

Conclusion

This study emphasizes that all the involved stakeholders need to better collaborate to upscale the school nutrition program in Dubai. This will require the formation of a unified governing body, which would identify and develop a single stream of resources, and sets in place a reliable, all encapsulating and equitable implementation plan along with an overarching monitoring and evaluation framework.

Hand washing practice among public primary school children and associated factors in Harar town, eastern Ethiopia: An institution-based cross-sectional study

Background

Hand washing with soap and water reduces the risk of diarrheal episode by 28-48% and acute respiratory infection by 20-50%. However, there is limited evidence on hand washing practices among students in Eastern Ethiopia, particularly in Harari town. Therefore, this study aimed to determine hand washing practice among primary school students and associated factors in Harar town, Eastern Ethiopia.

Methods

An institution-based cross-sectional study was applied among 670 students in Harar town from June 1 to 30, 2021. A multi-stage sampling was employed; 6 out of 20 schools were selected through simple random sampling, while eligible children from each school was selected by probability proportional to size sampling method. Data were collected using a pre-tested questionnaire with a face-to-face interview technique and via observation. The data were analyzed using SPSS software version 23. Binary and mult-variable analysis were used to determine the association between factors and outcome variable. Finally, a p-value of < 0.05 was considered to declare a statistically significant association.

Results

A total of 670 participants were included in the study, of which 248 (37.0%) had washed their hands [95% CI: 33.3-40.06]. Being in grade 8 Adjusted Odd Ratio[AOR = 4.9; 95% Confidence Interval (CI): 2.28-10.52], living in an urban area [AOR = 3.49; 95% CI: 1.29-9.40], having role models (parents [AOR = 4.41; 95% CI: 1.79-10.86], teachers [AOR = 3.69; 95% CI: 1.39-8.81], and health professionals [AOR = 3.17, 95% CI: 1.17-8.63]), availability of hand washing facility [AOR = 3.62; 95% CI: 1.57-8.34], access to soap and water [AOR = 2.89; 95% CI: 1.39-5.98] and being membership of water sanitation and hygiene (WASH) club [AOR = 2.39; 95% CI: 1.41-4.03] were found to be significantly associated with hand washing practice.

Conclusions

The current study found that nearly a third of students practiced proper hand washing. Hand washing practice was influenced by students' grade level, residence, referents (role models for hand washing), presence of a hand washing facility, access to water and soap, and membership of WASH club. Therefore, the finding revealed that there is a need to improve hand-washing practices in schools by concerned agencies.

Systems of communication in school-nurse led care coordination: A concept analysis

AIM

To analyze the concept of systems of communication in school nurse-led care coordination to develop an operational definition that will inform intervention development.

BACKGROUND

Communication has been identified as an essential attribute in care coordination. However, previous concept analyses of care coordination did not clearly define systems of communication or consider the context of school-based care coordination. Defining and conceptualizing systems of communication has important implications for improving school nurse-led care coordination.

METHODS

Concept analysis was conducted using Walker and Avant's eight-step concept analysis method. The literature was searched to identify supporting literature that was analyzed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist.

RESULTS

Systems of communication in school nurse-led care coordination can be defined as systems wherein care team members, led by the school nurse, collaborate by communicating information and knowledge through an individualized healthcare plan that is student/family-centered and shared through information systems. Attributes require developing an individual health plan that incorporates care coordination needs, information sharing with student/family consent, and a clear delineation of team member roles. Consequences include student/family outcomes, team member knowledge, and efficiency and accuracy of information.

CONCLUSIONS

Concept clarification and a synthesized definition allow for more effective measurement development for effective communication in school nurse-led care coordination. Students with healthcare needs in the school environment require systems of communication that efficiently work toward school nurse-led care coordination that addresses the student's health and academic outcomes.

Emotional expression visual mismatch negativity in children

Detection of changes in facial emotions is crucial to communicate and to rapidly process threats in the environment. This function develops throughout childhood via modulations of the earliest brain responses, such as the P100 and the N170 recorded using electroencephalography. Automatic brain signatures can be measured through expression-related visual mismatch negativity (vMMN), which reflects the processing of unattended changes. While increasing research has investigated vMMN processing in adults, few studies have been conducted on children. Here, a controlled paradigm previously validated was used to disentangle specific responses to emotional deviants (angry face) from that of neutral deviants. Latencies and amplitudes of P100 and N170 both decrease with age, confirming that sensory and face-specific activity is not yet mature in school-aged children. Automatic change detection-related activity is present in children, with a similar vMMN pattern in response to both emotional and neutral deviant stimuli to what previously observed in adults. However, vMMN processing is delayed in children compared to adults and no emotion-specific response is yet observed, suggesting nonmature automatic detection of salient emotional cues. To our knowledge, this is the first study investigating expression-related vMMN in school-aged children, and further investigations are needed to confirm these results.

Psychometric Assessment of the Handwriting Proficiency Screening Questionnaire (HPSQ)-Thai Version for Primary School-Aged Children

In this study, the original Handwriting Proficiency Screening Questionnaire (HPSQ) was translated into Thai and cross-culturally adapted for use among school-aged children in Thailand. Additionally, the initial psychometric properties of the new Thai version were assessed, including internal consistency, construct validity, and content validity. The original HPSQ was forward-translated by two independent translators from English to Thai and then back-translated. A final consolidation was conducted by an expert committee to develop the Thai HPSQ. In the psychometric evaluation, content validity was quantified using the item-objective congruence (IOC) value for each item. Intra-rater and inter-rater reliabilities were also assessed. Internal consistency was measured using Cronbach’s alpha coefficient, and confirmatory factor analysis models were used to examine its construct validity. The Thai version of the HPSQ had excellent internal consistency (α = 0.92), good construct, and content validity (IOC value > 0.6). Intra-rater reliability was good (intraclass correlation coefficient (ICC) = 0.98), and inter-rater reliability ranged from fair to good (ICC = 0.46−0.77). Factor analysis revealed that a three-factor model best fitted the data. Thus, the Thai version of the HPSQ is a reliable and valid instrument for handwriting evaluation among Thai school-aged children. It can be useful for teachers and therapists to identify students with handwriting problems.

Impact of a 5-Year Mass Drug Administration Programme for Soil-Transmitted Helminthiases on the Spatial Distribution of Childhood Anaemia in Burundi from 2007 to 2011

Background: Childhood anaemia affects 1.8 billion people globally. Little is known about the long-term impact of mass drug administration (MDA) for the control of soil-transmitted helminthiases (STH) on the spatiotemporal variation of anaemia prevalence and severity. We describe the long-term spatiotemporal impact of a 5-year STH MDA programme (2007−2011) on the prevalence of anaemia and anaemia severity in school-aged children (SAC) in Burundi. Methodology/Principal Findings: We used annual haemoglobin concentration and STH data collected during 2007−2011 in 31 schools in Burundi. Spatial dependence in prevalence and severity of anaemia was assessed using semivariograms. Bayesian geostatistical models were developed to (a) quantify the role of STH (adjusted for other anaemia determinants) in the spatiotemporal distribution of anaemia prevalence/severity, and (b) predict the geographical variation of both outcomes across Burundi. Adjusted population data were used to estimate the geographical distribution of the number of SAC at risk of anaemia and with low and moderate/severe anaemia. Infections with Ascaris lumbricoides and Trichuris trichiura were positively and significantly associated with childhood anaemia; hookworm infections were not. A significant decrease in anaemia prevalence, from 40−50% (2008) to 10−20% (2011) was predicted in western areas. The predicted prevalence of low-severity anaemia decreased from 40−50% (2008) to <20% (2011) in southern and eastern areas. Moderate/high-severity anaemia was concentrated in western regions of Burundi, with pockets of moderate/high-severity anaemia in central and northern regions in 2008. The overall number of predicted anaemic children decreased from 443,657 (2008) to 232,304 (2011), with a resurgence after MDA disruption in 2010 (to 480,605). Prevalence of low- and moderate-severity anaemia was higher in boys than in girls. Conclusions/Significance: Despite ongoing MDA, the prevalence of anaemia in SAC remained high and increased in certain parts of the country. It is recommended that MDA programmes targeting STH are complemented with specific anaemia interventions.

Impact of Teacher Incentive Intervention on Students' Vision Healthcare Uptake: A Cluster-Randomized Controlled Trial

Less than one-third of rural Chinese children with refractive error own or wear eyeglasses. To study the effect of teacher incentives on the acceptance of vision care offered to rural students with uncorrected refractive error, we conducted a cluster-randomized controlled trial in 18 townships in one county in Shaanxi Province. Primary and junior high schools within each township were assigned to either intervention (all teachers received an incentive) or control (no teacher incentives were offered) groups. A total of 42 schools were assigned to either the intervention group (13 schools) or the control group (29 schools). Teachers in the intervention group could elect to receive high-value (sunglasses worth USD 148), moderate-value (eyeglasses worth USD 89), or cash incentives (USD 35) if ≥70% of eligible students (uncorrected visual acuity (VA) ≤ 6/12 in both eyes and corrected VA ≤ 6/9.5 in both eyes) in the teacher's class visited a program-affiliated vision center (VC) within 60 days after their vision screening. Among 8238 students, 3401 (41.2%, of which 53.0% were girls with a mean age of 12 (SD 1.75)) met the enrollment criteria and were randomly allocated to the intervention (n = 1645, 49.0%) and control groups (n = 1579, 51.0%). Among these, 3224 (94.8%) completed the study and underwent analysis. Nearly equal numbers of students had classroom teachers selecting the high-value (n = 524, 31.9%), moderate-value (n = 582, 35.4%), and cash incentives (n = 539, 32.8%). The rate of the acceptance of offered vision care was significantly higher in the intervention group (382/1645 = 23.2%) compared to the control group (172/1579 = 10.9%, 95% confidence interval for observed difference 12.3%, p < 0.001). Teacher incentives appeared effective in improving Chinese rural school-aged children's uptake rate of vision services provided by county hospital-based VCs.
