ABSTRACT
@#Introduction: The problem of double nutrition includes undernutrition and overnutrition, often found in elementary school children. Nutritional problems in childhood will cause disturbances in children’s cognitive abilities, especially in remembering. The purpose of this study was to analyse the relationship between nutritional status and shortterm memory in 5th grade school-aged children at one of the Elementary schools in Surabaya, East Java, Indonesia. Methods: This research design is non-experimental with a correlation method and cross-sectional approach. A total of 111 respondents were chosen with simple random sampling. Data collection used observation sheets for nutritional status and questionnaire sheets for short-term memory. Results: Chi-square test SPSS statistical test showed that p < 0.001 (α = 0.05) where H1 was accepted, meaning that there was a significant relationship between nutritional status and short-term memory in school-aged children at one of the Elementary schools in Surabaya, East Java, Indonesia. There were 65 respondents with normal nutritional status and 63 respondents with high short-term memory. Moreover, a good nutritional status of the child and a good neurological function of the child’s brain, impact the ability to remember. Conclusion: There is a correlation between nutritional status and short-term memory in school-aged children. Most of the respondents have nutritional status and short-term memory in the normal category and high category at the age of elementary school children. In line with the conclusion, the school is expected to periodically monitor nutritional status through UKS (School Health Unit).
ABSTRACT
BACKGROUND@#School-aged children bear a lot of difficulties and discomforts brought about by the new normal during the COVID-19 pandemic.@*OBJECTIVES@#This study aimed to examine the general well-being of children during the pandemic, how the children are coping with all the challenges, and parents' strategies to help their children cope@*METHODOLOGY@#This study utilized a descriptive correlational research design with purposive sampling. Data was collected through an online survey. The standardized Kidcope-Child version was utilized to measure children's coping, while the Pediatric Quality of Life Inventory (PedsQL)™ 4.0 Short Form 15 Generic Core Scales was utilized to measure the children's well-being.@*RESULTS@#A total of 134 parents participated in the study. No significant relationship was found between the age, sex, and coping strategies of the children, as well as between the age and well-being of children. Male children experienced more difficulty in physical functioning (p-value= 0.028), social functioning (p-value= 0.017), and overall well-being (p-value= 0.031) compared to female children. The computed mean for parents' helping strategies was between 2.67 to 2.78, which lies between the categories of sometimes (2) to always (3).@*CONCLUSION@#School-aged children were found to be using more positive coping strategies than negative coping strategies during the pandemic. They have “sometimes” to “almost no” experience of difficulty in terms of the five functions of well-being. Parents used the six fundamental tasks of parenting to help their children cope.

ObjectiveTo explore the effects of after-school tutoring for school-age children on their emotions and behaviors， and to provide a basis for developing after-school tutoring and psychological support strategies for school-age children. MethodsFour elementary schools in a district of Shanghai were selected by simple random sampling method. Whole group sampling was conducted by class， and parents of students were surveyed by general questionnaire and the scale of strengths and difficulties. Information was collected on the basic conditions of children and families and the results were compared and analyzed. ResultsThis study showed that 88.26% of children attended extracurricular classes， of which 26.16% attended 3 or more classes， 42.5% attended cultural classes， 28.3% attended sports classes， and 59.8% attended art classes. Children who did not attend classes had higher pro-social scores. Children who attended reading class had lower scores for emotional problems that was a protective factor for emotional problems. Children who chose extracurricular programs in sports and reading also had lower overall scores for difficulties. Excessive use of electronic devices by school-age children on weekdays or weekends had a negative effect on emotional and conduct problem scores regardless of whether they chose extracurricular programs. It appeared that the choice of cultural programs， art programs and different levels of exercise intensity had no effect on children's emotions and behaviors. ConclusionFor children with low pro-social level， extracurricular classes should be carefully selected. For extracurricular classes， more reading and sports-related courses can be considered， which have positive effects on school-age children’s emotions and behaviors. Regardless of the choice of extracurricular classes， try to avoid excessive online classes.

Objective:To evaluate the effect of eye-covering pretreatment on acute delirium in ophthalmology preschool-age children who underwent binocular and monocular surgery by general anesthesia.Methods:The 300 preschool-age children who underwent general anesthesia of elective ophthalmic surgery in the Second Affiliated Hospital, Zhejiang University School of Medicine, from August 2019 to February 2021 were selected as the research object. They were divided into control group and blindfold group with 150 cases each by random number-table. Children in the control group received regular education on cartoon animation videos before surgery; children in the blindfold group received eye-covering pretreatment on the basis of cartoon animation videos(monocular surgery with monocular cover, binocular surgery with binocular cover). The Modified Yale Preoperative Anxiety Scale (m-YPAS) , the Nursing Delirium Screening Scale(NU-DESC), the incidence rate of delirium and the score of postoperative nursing difficulty were compared between two groups.Results:The 271 cases were completed in this study, including 129 cases(monocular surgery 66 cases, binocular surgery 63 cases) in the blindfold group and 142 cases (monocular surgery 73 cases, binocular surgery 69 cases) in the control group. The preoperative m-YPAS score, the postoperative NU-DESC score, the incidence rate of acute delirium and postoperative nursing care difficulty score of monocular surgery in the blindfold group , monocular surgery was (40.28 ± 15.02) points, 1.00 (0.00, 2.00) points, 27.3%(18/66), 1.00 (1.00, 2.00) points,and binocular surgery was (41.69 ± 16.35) points, 1.00 (0.00, 2.00), 39.7%(25/63), 1.00(1.00, 2.00); in the control group, monocular surgery was (46.28 ± 15.76) points, 2.00 (1.00, 3.00) points, 67.1% (49/73), 2.00 (1.00, 3.00) points, and binocular surgery was (47.77 ± 14.82) points, 3.00 (2.00, 4.00) points, 82.6% (57/69) and 2.00 (1.50, 3.00) points respectively. The difference between the two groups was statistically significant ( t= -2.29, -2.24, Z values were -5.74 - -2.95, χ2= 32.94, 25.78, all P<0.05). The preoperative m-YPAS score, the postoperative NU-DESC score, the incidence rate of acute delirium and postoperative nursing care difficulty score of monocular surgery patients in the blindfold group had no significantly statistical difference with that of binocular surgery patient (all P>0.05) . Conclusions:Monocular/ binocular eye-covering pretreatment can effectively decrease the preoperative m-YPAS score, the postoperative NU-DESC score, incidence rate of acute delirium and the postoperative nursing care difficulty in preschool-age children who underwent general anesthesia both monocular or binocular surgery. There was no difference in the application effect of monocular or binocular surgery.
ABSTRACT
Objectives@#The Department of Health (DOH) aims to reduce the prevalence of intestinal parasitism and proportion of heavy intensity of infection in the country by 2022. Among the interventions is school-based mass drug administration (MDA). Regular assessment of MDA gives guidance to the DOH. The aim of this survey was to determine the prevalence of soil transmitted helminthiasis and histosomiasis among public school children ages 5 to 16 years old. @*Methodology@#A cross-sectional, school-based study using multi-stage stratified cluster sampling was conducted from 2013 to 2015, covering the National Capital Region (NCR), and all provinces, except Maguindanao and Sulu. Stool samples were examined using the duplicate Kato Katz (KK). @*Results@#Of the 26,171 school children with stool samples examined, 7,440 (28.4%) were infected with at least one soil-transmitted helminth (STH). Infections among male students were significantly higher than female students (31.0% versus 26.0%). Heavy, moderate, and light intensity of infections were 3.2%, 29.0% and 67.7%, respectively. STH cumulative prevalence per province ranged between 0.5% and 89.5%. Schistosomiasis infections were detected in known non-endemic provinces: Ilocos Norte, Biliran, Tawi-Tawi, Basilan, and Dinagat Islands. Majority (68%) of the infections were with single parasites but as many as five parasites were detected in one child. Infections with heterophyids were also observed. @*Conclusion@#While the national prevalence of schistosomiasis was less than 1.0%, the cumulative prevalence of soil-transmitted helminthiasis among school-aged children was higher than the global figure of 24.0%.

Introduction: Saliva is the most important biological factor to protect against dental caries. When saliva flow is reduced, oral health problems such as dental caries and oral infections can develop. It was suggested that the effect of low salivary pH is more in plaque close to the area of susceptible tooth surface. The presence of saliva in pre-school age children is a significant indicator in oral health assessment oral health. There has been an association between salivary cortisol and socioeconomic variable. Descriptions above have encouraged us to examine the salivary pH, feature, and volume of pre-school-aged community. Thus, this study was aimed to describe the differences in salivary pH, feature, and volume of the children in the three pre-school with different location and socioeconomics aspect. Methods: Descriptive survey, with a population of pre-school students in 3 different kindergartens with different socioeconomic environment. Inclusion criteria were the pre-school-aged community and got permission from parents. Exclusion criteria were a pre-school-aged community under medication treatment causes hyposalivation or hypersalivation and children who did not want to be involved in the study, with total sampling as the sampling technique, resulted in as much a 101 respondents as the study sample. The saliva was collected with unstimulated technique. Data analysis was performed using relative frequency distribution. Results: The salivary pH was slightly higher in male children than female by 0.1. The average pH value was 7.25. The salivary feature was mostly frothy bubbly, followed by thin and watery, and the sticky bubbly feature was found the least. The salivary volume of the pre-school-aged community was mostly in the very less category, followed by the less category, with no normal category was found. the p-values of salivary pH and salivary features were below 0.05 There are no significant differences between the salivary pH and salivary feature of children from the three studied kindergartens. However, there is a significant difference in the salivary volume found in children from kindergartens located in high socioeconomic standard and middle socioeconomic standard areas, which have a higher salivary volume than the children from kindergartens situated in areas with lower socioeconomic standard. Conclusion: since the reduced salivary volume was associated to children with lower socioeconomic standard, this association can justify the higher risk for caries described in the literature (AU)
Introdução: A saliva é o fator biológico mais importante na proteção contra a cárie dentária. Quando o fluxo salivar é reduzido, podem ocorrer problemas na saúde bucal, como cáries e infecções orais. Foi sugerido que o efeito do baixo pH salivar é aumentado na placa, próxima à área de superfície dentária suscetível. A presença de saliva em crianças em idade pré-escolar é um indicador significativo na avaliação da saúde bucal. Houve associação entre cortisol salivar e variáveis socioeconômicas. As descrições acima nos encorajaram a examinar o pH salivar, características e volume da comunidade em idade pré-escolar. Assim, este estudo teve como objetivo descrever as diferenças de pH, característica e volume salivar das crianças de três pré-escolas com localização e aspectos socioeconômicos distintos. Material e Métodos: Pesquisa descritiva, com população de estudantes da pré-escola de três diferentes jardins de infância com diferentes ambientes socioeconômicos. Os critérios de inclusão foram comunidade em idade pré-escolar e permissão dos pais. Os critérios de exclusão foram comunidade em idade pré-escolar sob tratamento medicamentoso que causa hipossalivação ou hipersalivação e também crianças que não quiseram se envolver no estudo, com amostragem total resultando em 101 entrevistados como a amostra do estudo. A saliva foi coletada com a técnica não estimulada. A análise dos dados foi realizada usando distribuição de frequência relativa. Resultados: O pH salivar foi ligeiramente superior nas crianças do sexo masculino do que no feminino em 0,1. O valor médio do pH foi de 7,25. O aspecto salivar era principalmente espumoso com bolhas, seguido de aspecto tênue e aguado, e o aspecto pegajoso e espumante foi o menos encontrado. O volume salivar dos estudantes em idade pré-escolar encontrava-se majoritariamente na categoria inferior a todas, seguida da categoria menos, não sendo encontrada nenhuma categoria normal, onde os valores de p do pH salivar e características salivares estavam abaixo de 0,05. Não há diferenças significativas entre o pH salivar e a característica salivar das crianças dos três diferentes jardins de infância estudados. No entanto, existe uma diferença significativa no volume salivar encontrado em crianças de creches localizadas em áreas de médio e alto padrão socioeconômico, que apresentaram maior volume salivar do que as crianças de creches situadas em áreas de menor padrão socioeconômico. Conclusão: O volume salivar reduzido esteve associado a crianças com menor padrão socioeconômico, logo essa associação pode justificar o maior risco de cárie descrito na literatura. (AU)

Abstract Objective: Using a wide and representative sample of adolescents from 37 countries, this study aimed to analyze how age changes adolescents' healthy lifestyle. Methods: The study included 148,839 adolescents who participated in the Health Behavior in School-aged Children 2010 survey. A composite score of a healthy lifestyle was created using the combination of daily physical activity, daily fruit and vegetable consumption, <2 h daily on screen-based behaviors, abstinence from alcohol, and abstinence from tobacco products. Healthy lifestyle measures were based on self-report. Results: 4.7% of boys and 4.4% of girls aged 11 years, 3% of boys and 2% of girls aged 13 years, and 1.5% of boys and 0.8% of girls aged 15 scored perfectly on the healthy lifestyle score. As age increased, the prevalence of adolescents with a healthy lifestyle decreased. In 37 countries and regions, the prevalence of healthy behaviors decreased linearly between early adolescence and the age of 15 years. Conclusions: In general, adolescents do not have a healthy lifestyle. Results from this study highlight that there is still much work to be done in promoting healthy lifestyles and to raise awareness among adolescents of the potential risk to their health status.

There has been an increase in the consumption of junk food (JF) among school-aged children (SAC) possibly leading to obesity and diet-related diseases among them. We do not have evidence on consumption of JF in rural areas; hence, we conducted a study to assess the consumption of JF by SAC in rural, Himachal Pradesh. A total of 425 children in the age group of 12� years studying in 30 government schools (clusters) were included. The clusters were selected using population proportionate to size sampling methodology. We found high prevalence (36%) of consumption of JF among SAC during the last 24 h. Efforts should be taken to reduce the consumption of JF by promotion of healthy dietary habits and educating children about the ill effects of JF.
ABSTRACT
Objective:To study the distribution and related factors of aggressive behavior among school aged children in Nanjing.Methods:Totally 4678 primary school students in Nanjing were sampled by cluster random sampling in this study.The General questionnaire and Achenbach's child Behavior Checklist were used to investi gate the general situation and aggressive behavior.Results:The rate of aggressive behavior of school-age children in Nanjing was 3.6 ％ (167/4678).Multivariate logistic regression analysis indicated that democratic parenting style [other parenting styles (OR =1.94,95％ CI =1.10-3.42),mixed parenting style(OR =1.96,95％ CI =1.35-2.85)],and genetic screening before birth (OR =0.71,95％ CI =0.52-0.99) were protective factors for children's aggressive behavior.The factor figures of aggressive behavior were positively correlated with that of oth er behavior problems in Pearson correlation analysis (r =0.52-0.80,Ps ＜0.01).Conclusion:About 3.6％ of the school aged children in Nanjing have aggressive behavior.It is more likely to have aggressive behaviors for children who is in other parenting styles except the democratic style and never have the genetic screening before birth.And children who with aggressive behavior may co-occur with other behavior problems.
ABSTRACT
Objectives To investigate the association between the dynamics of thyroid volume and the changes of physical growth in school-aged children as well as to compare the applicability of different thyroid volume indexes,so as to explore more reliable methods for the assessment of thyroid volume.Methods In October 2012,a multi-stage cluster sampling method was used to select a primary school in Minhang district of Shanghai,Haimen city of Jiangsu province and Yuhuan city of Zhejiang province,respectively.In these areas,a total number of 784 students aged 8-10 years were enrolled in the cohort.Demographic data was collected,while height and weight were measured,with BMI and body surface area (BSA) were calculated.Thyroid volume was examined by B-ultrasonography.Height volume index (HVI),weight and height volume index (WHVI),BMI volume index (BMIV) and BSA volume index (BSAV) were all applied to correct the thyroid volume.All students were followed up,one year later.Results A total of 769 students with complete data on thyroid volume and physical growth were enrolled,including 378 boys (49.16％) and 391 girls (50.84％).Thyroid volume showed an increase with age,while growth of thyroid volume reduced with the increase of age (P＜0.001).The thyroid volume showed a correlation with the changes of physical growth.The growth of height appeared as the dominant influencing factor for thyroid volume growth in those aged 8 and 10 years (P＜0.05),while the growth of weight,BMI and BSA were all influencing factors for thyroid volume on students aged 9 years (P＜0.05).Conclusions Thyroid volume in school-aged children was a factor not only associated with age but also with physical growth which had not been considered in the currently used criteria.The inclusion of items as iodine intake,age,physical growth into the thyroid volume indexes seemed to be more reliable,in practice.For the assessment of goiter,HVI for students aged 8 and 10 years and BMIV for students aged 9 years might serve as better indicators.

ABSTRACT
Objective To investigate the status and the influencing factors of thyroid volume of children aged 8-10 years in Hefei City.Methods In 2016,according to the requirements of "National Iodine Deficiency Disorders Surveillance Plan (the 2016 Edition)",the method of multistage stratified sampling was used in 9 counties (cities,districts) of Hefei.Five primary schools were randomly selected from each county (city,district),with one in each direction (the east,west,south,north and center),then 40 children aged 8-10 years (male ∶ female =1 ∶ 1,with similar age distribution) were randomly chosen in each primary school.The thyroid volume,height and weight were measured.In addition,a questionnaire with the items including personality,learning pressure,dietary habits,related disease history and contact history was designed and used to collect the data of the subjects.Results Totally 1 800 children aged 8-10 years were selected from 45 primary schools in 9 counties (cities,districts).The mean thyroid volume was (3.009 ± 1.197) ml.Totally 71 people were found with thyroid enlargement and the goiter rate was 3.9％,which was in the range described in the elimination iodine deficiency disorders (IDD) standard (＜ 5％).Univariate analysis showed that for children in different age groups,seafood consumption frequency,radiological examination,height,and body mass,the thyroid volumes were significantly different (P＜ 0.05);Multivariate linear regression showed that body weight and height were main factors affecting the thyroid volume of children aged 8-10 years in Hefei City,the standard partial regression coefficient are 0.288 and 0.140,respectively.Conclusions The thyroid volume of the 8-10 years old children is generally in the normal range in Hefei.Goiter rate is lower than the standard for elimination of iodine deficiency The findings have showed that not only age,but also height,body mass and other factors should be considered while evaluating the influencing factors of the thyroid volume of school-aged children.
ABSTRACT
Pediatric obesity is a major public health problem in the country. The imbalance between caloric intake and expense has been recognized as a major contributing factor, however, despite many strategies to combat this pathology the results remain discouraging. The mother is an important treatment intermediary that can have a distorted motherly perception (DMP) about their child's nutritional status. The purpose of this study was to assess motherly perception of body image (MPBI) of their school-age children. We selected mothers with children between 7 and 17 years old from schools in Santiago, Chile. We assessed nutritional status with body index mass (BMI) and pubertal growth (Tanner) and compared MPBI with actual nutritional status. We observed that 54.8% of mothers of obese children and 78.3% of mothers of overweight children had DMP, estimating their child as thinner. DMP among mothers of overweight and obese children could affect treatment adherence and is a key point for intervention.
La obesidad pediátrica es un importante problema de salud pública en el país. El desequilibrio entre ingesta y gasto energético ha sido reconocido como la principal causa, pero pese a las múltiples estrategias para enfrentar esta patología los resultados continúan siendo desalentadores. La madre es un mediador importante en el tratamiento, pudiendo influir la distorsión de la imagen corporal (DIC) en el estado nutricional (EN) de sus hijos. El propósito de este trabajo fue evaluar en población escolar la percepción de la imagen corporal (PIC) de la madre hacia su hijo. Se seleccionaron madres con hijos con edades de 7 a 17 años de colegios de Santiago de Chile. Se determinó el EN según índice de masa corporal (IMC) y desarrollo puberal (Tanner). Se evaluó la PIC de la madre comparándose con lo real. Se observó que el 54,8% de las madres de niños obesos y el 78,3% de las madres de niños con sobrepeso presenta DIC, evaluando a su hijo más delgado. La DIC de la madre con su hijo con sobrepeso u obeso, podría repercutir en la escasa adherencia al tratamiento, siendo un punto clave en el cual intervenir.

<p>The study aimed to assess a self-reported questionnaire about physical activity (PA) from the Health Behaviour in School-aged Children (HBSC) using triaxial accelerometer as a criterion. Elementary school boys (N=292) and girls (N=313) in the fourth grade and higher completed the questionnaire and wore an accelerometer for at least 10 h/day for at least 4 days. The phi coefficients of the chi-square test 2-way tables (active/inactive as measured using the HBSC questionnaire × achievement/non-achievement of the recommended 60-min moderate to vigorous PA [MVPA] as measured using the accelerometer) were 0.25 (P<0.001), 0.17 (P=0.009), and 0.08 (P=0.217) for all children, boys, and girls, respectively. The sensitivity and specificity in boys were 82% (95% confidence interval [CI]=78-86%) and 34% (95%CI=26-41%) respectively, while the those of girls were 52% (95%CI=40-63%), 57% (95%CI=55-60%). The positive predictive value in boys was 70% (95%CI=66-73%) and negative predictive value in girls was 83% (95%CI=79-87%). The independent t-test showed that moderate PA (MPA), vigorous PA (VPA), and MVPA min/day of active children were significantly higher than those of inactive children (range of Cohen’s d=0.38 to 0.71). Area under the curve (AUC) of the VPA (AUC = 0.60–0.73) in girls was significantly higher than that of the MPA (AUC = 0.52–0.65) and MVPA (AUC = 0.54–0.67). Our results supported that the HBSC self-reported questionnaire has acceptable, but limited agreement for assessing achievement/non-achievement of the MVPA recommendation, and could estimate the differences in the MPA, VPA, and MVPA min/day of children.</p>
ABSTRACT
Coronary artery involvement remains the most important complication with Kawasaki disease (KD). Additional myocardial injury can be caused by inflammatory response and ischemic event. However, the long-term outcome of myocardial function has not been fully known in KD. The purpose of this study is to evaluate myocardial function in school-aged children who had the past history of KD. Sixty-seven children in the second grade of elementary schools, who had the past history of KD, were included. Echocardiographic measurements of each coronary artery and myocardial function were obtained as the long-term follow-up data, and compared with the baseline data at the time of initial presentation of KD. The mean age of the subjects was 8.6 ± 2.4 years, and 4.3 ± 3.4 years have passed since the diagnosis of KD. Among the echocardiographic data, interventricular septum thickness at end-diastole (IVSd), LV internal diameters at end-systole (LVIDs), maximal velocity of late diastolic filling across mitral valve (mitral A) flow, maximal velocity of early diastolic filling across mitral valve (mitral E)/A ratio, mitral inflow E wave to peak early diastolic tissue velocity (E/E') ratio showed significant differences between the baseline and follow-up measurements. Coronary Z-score of left main artery (LMA), left anterior descending (LAD), and right coronary artery (RCA) showed no significant difference. The school-aged children with the past history of KD may have diastolic dysfunction. Therefore, appropriate assessment of myocardial function would be recommended during the follow-up period in children with KD.

Objective The aim of this paper was to analyze the association between different types of obesity and cardiovascular risk factors (CRFs) in school-aged children.Methods 3508children aged 6-18 years old including 2 054 non-obese and 1 454 obese children were chosen as the population under study,from Beijing Children and Adolescents Metabolic Syndrome Study.Demographic data was collected through questionnaires while height,weight,waist circumference,and blood pressure were measured through physical check-up.Fasting blood glucose and blood lipids were also tested.Children were divided into four groups:without obesity,with general obesity,with abdominal obesity and with combined obesity.CRFs including dyslipidemia,impaired fasting glucose (IFG),and hypertension were scored.Multiple linear regression and logistic regression analyses were performed to assess the association between different types of obesity and CRFs.Results From non-obese children,children under general-obesity,abdominal obesity and those with combined types of obesity,there appeared an increasing trend in the levels of blood pressure,blood glucose,and blood lipids,the prevalence dyslipidemia and hypertension (P＜0.001).There were no significant differences in the risks of IFG among four types of obesity.After controlling for age,sex,and puberty stage,when compared with non-obese children,those children with abdominal obesity or combined types of obesity had 1.54 and 2.51 times of risks to only one CRF,while generally obese children had similar risk of dyslipidemia.When compared to the non-obese ones,children with general obesity,abdominal obesity,or combined types of obesity showed 3.32,2.21 and 7.42 times of risks to ≥2CRFs and 3.10,3.67 and 10.75 times of risks to ≥3 CRFs.The cluster of CRFs increased with the levels of obesity (P＜0.001).Conclusion Levels and cluster of CRFs were increasing along with the levels of obesity in school-aged children in Beijing.Children with combined types of obesity had the highest risk of clustering CRFs,followed by those with abdominal obesity and general obesity.
ABSTRACT
Objective To explore the characteristics of T wave alternans (TWA) in aortic stenosis (AS) in school-aged children. Methods TWA was analyzed in 15 AS patients and 60 age-matched normal children using Microvolt T-Wave Alternans and the incidence of sustained TWA was compared between two groups. Myocardial ischemia during treadmill test was studied in sustained TWA and non-sustained TWA in AS patients. Results Compared with normal children, the incidence of sustained TWA was signiifcantly increased in AS group (P<0.01). In AS school-aged patients, the incidence of myocardial ischemia is higher in sustained TWA than in non-sustained TWA during treadmill test (P<0.05). Conclusions AS school-aged children have electrophysiologic basis for sunstained TWA. TWA is closely related to myocardial ischemia during treadmill test. Sustained TWA could be used as an important electrophysiologic index to assess the cardiac function in children with AS.
ABSTRACT
BACKGROUND/OBJECTIVES: Recently, there has been an increased interest in the importance of family meals on children's health and nutrition. This study aims to examine if the eating habits and eating behaviors of children are different according to the frequency of family dinners. SUBJECTS/METHODS: The subjects were third-grade students from 70 elementary schools in 17 cities nationwide. A two-stage stratified cluster sampling was employed. The survey questionnaire was composed of items that examined the general characteristics, family meals, eating habits, eating behaviors, and environmental influence on children's eating. The subjects responded to a self-reported questionnaire. Excluding the incomplete responses, the data (n = 3,435) were analyzed using chi2-test or t-test. RESULTS: The group that had more frequent family dinners (> or = 5 days/week, 63.4%), compared to those that had less (< or = 4 days/week, 36.6%), showed better eating habits, such as eating meals regularly, performing desirable behaviors during meals, having breakfast frequently, having breakfast with family members (P < 0.001), and not eating only what he or she likes (P < 0.05). Those who had more frequent family dinners also consumed healthy foods with more frequency, including protein foods, dairy products, grains, vegetables, seaweeds (P < 0.001), and fruits (P < 0.01). However, unhealthy eating behaviors (e.g., eating fatty foods, salty foods, sweets, etc.) were not significantly different by the frequency of family dinners. CONCLUSIONS: Having dinner frequently with family members was associated with more desirable eating habits and with healthy eating behaviors in young children. Thus nutrition education might be planned to promote family dinners, by emphasizing the benefits of having family meals on children's health and nutrition and making more opportunities for family meals.
