Usefulness of a salt check sheet for elementary school and junior high school children.

There are no known methods to easily evaluate the dietary salt intake of children. We hypothesized that the salt check sheet, for which validity has been confirmed in both hypertensive outpatients and in the general population, can be used to assess dietary salt intake in children. We enrolled 188 healthy schoolchildren (mean age 11.2±1.1years, 53.2% boys) and asked them to answer both the salt check sheet and a brief self-administered dietary history questionnaire for Japanese schoolchildren aged 6-18years (BDHQ15y). The mean total salt check-sheet score was 12.7±4.0 points (range: 4-24 points), and the estimated daily salt intake from the BDHQ15y was 12.1±3.7g (range: 4.7-27.2g). The total check-sheet score was significantly positively correlated with the estimated daily salt intake from the BDHQ15y (r=0.408, P<0.001). Thirty-one study participants were assigned to the "low" salt group (total score on the salt check sheet was 0-8 points), 78 participants to the "medium" salt group (9-13 points), and 79 participants to the "high and very high" salt group (≥14 points), and a comparison estimating daily salt intake from the BDHQ15y among the three groups was performed. Daily salt-intake levels tended to increase as the group of total check-sheet scores increased: "low" vs "medium" vs "high and very high" salt group levels were 9.5±3.1 vs 11.6 vs 13.5±3.9, respectively (P<0.001). This demonstrates that the salt check sheet is a useful tool to easily assess dietary salt intake in children.

Why Has Japanese Educational Reform Come to a De Facto End?

A reform of public education in Japan took place from the 1980s, coming to a de facto end in 2013. The reform, which affected large numbers of Japanese children, focused on creating a more flexible, relaxed form of education by reducing the amount included in the curriculum. However, the effects of this reform have been ambiguous, and we therefore aimed to assess them more accurately. We assessed the effects of the reform by looking at the private educational costs of households during the reform period, using the data from a time series survey conducted by the Japanese government. Our evidence shows that the auxiliary study expenses of children in public junior high schools increased steadily, and the proportion of children from households in the highest income group attending private junior high schools also rose during the reform period. This evidence indicates that the reform had unexpected results. It may have triggered a widening of children&amp;rsquo;s academic ability gap depending on household wealth. There is also no comprehensive evaluation of how pressure-free education affected the academic results of Japanese children. We drew some lessons from this experience to suggest what is needed for successful educational reform.

Regional disparities in road traffic injury rates involving elementary and junior high school children while commuting among Japan’s 47 prefectures between 2004 and 2013

ObjectivesTo investigate the extent and patterns of regional disparities of road traffic injury rates involving elementary and junior high school children while commuting among Japan’s 47 prefectures. MethodsWe conducted a cross-sectional ecological study using the national police data for 2004–2013 on the number of children who were killed or seriously injured (KSI) in traffic collisions stratified by prefecture, grade, mode of transport, and purpose of trip (commuting or non-commuting). We calculated stratified KSI rates by dividing the number of KSI cases by the corresponding number of children and presented these rates for the 47 prefectures. Also, for pedestrian elementary school children and cyclist junior high school children, we regressed the KSI rates while commuting by prefecture on the non-commuting KSI rates and the proportion of people who live in the urban, densely inhabited districts. ResultsThere were 6463 KSI cases while commuting. The ratios of the highest KSI rate to the lowest KSI rate among prefectures were 12, 30, and 58 for pedestrian elementary school children and pedestrian and cyclist junior high school children, respectively. The non-commuting KSI rates and the proportion of those living in densely inhabited districts were positively and inversely associated with the commuting KSI rates, respectively. The analysis of the residuals of the regression models did not identify prefectures with significantly higher or lower KSI rates while commuting than others. ConclusionsThere were large inter-prefecture disparities in the KSI rates while commuting, and the disparity was especially large among cyclist junior high school children.

As the largest Muslim country in the world, the tradition of memorizing the Qur'an is also strong in Indonesia. Noted since before independence, many scholars of the Qur'an are born this earth. In memorizing the Qur'an people have different methods and ways. However, whatever method is used will not be separated from repeated readings to be able to say it without seeing a mushaf at all. This study aims to describe the method of memorizing the Qur'an most effectively for junior high school children. From the results of the discussion can be summarized as follows: 1. In principle all methods are good to be used as a guide memorize Al-Quran, either one of them, or used everything in accordance with the needs and as an alternative to the way memorize the monotone, so degan so will eliminate saturation in the process of memorizing Al-Quran. 2. Element tahfiz strategy should be prioritized when preparing the curriculum for teaching and learning tahfiz. Tahfiz teachers and students must focus on these strategies and apply them in tahfiz teaching and learning. This is to ensure that students achieve superior quality performance in memorizing the Qur'an.

Implementation of Nutrition Education to Knowledge, Behaviour, and Performance of Junior High School children

The prevalence of obeslity increases from year to year. One of the factors that causes obesity was food habits. Precautions need to be taken to undergo this phenomenoms. One effort that can be done was to provide nutrition education to children. This research studied the role of nutrition education given to school age children (8th grade junior high school) towards knowledge, behavior, and overall performance. The study was conducted by giving pre-test and post-test to students who were divided into 2 groups. The first group treated with nutrition education, while the second group did not. Each group consisted of 37 students. The results showed that nutrition education have a strong influence in to knowledge, behaviour, and also the performance of the student. Students who are involved in research are included in the middle to lower class of economics so there are not many opportunities to choose food. Research needs to be done in other locations with middle to upper economic levels.

Actitudes de padres mexicanos acerca de la igualdad de género en los roles y liderazgos familiares

Se analizan las actitudes de padres de familia sobre la igualdad de género en los roles y liderazgos familiares en los sectores urbano-populares de Tijuana, México. Se usa la Encuesta a Padres de Familia con Hijos en Escuelas Secundarias en Tijuana, B.C., 2015, con información para 2 560 padres con hijos e hijas en escuelas secundarias públicas. Se estiman cuatro índices sobre la igualdad de género en el rol materno, los roles domésticos y los liderazgos familiares, y se crean modelos de regresión logística. Los hallazgos indican la coexistencia de un gran valor asignado al rol de la maternidad en la vida de las mujeres, así como actitudes moderadamente entusiastas a favor de la igualdad de género en los roles domésticos, pero menos entusiastas respecto de compartir e intercambiar los liderazgos familiares. El nivel educativo de los padres muestra ser la única variable estadísticamente significativa en su asociación con los cuatro índices considerados.

Survey on the Prevalence of Allergic Rhinitis in Junior High School Students in Isfahan, Iran

Background Allergic rhinitis (AR) is a common form of nose inflammatory disease that occurs when the mucosal immune system overreacts to environmental allergens especially in the air. It’s absolutely clear that the prevalence of AR varies between different countries, and even between the various areas of a country. The purpose of present investigation is to determine the prevalence of AR, as most common allergic disorders, in the children of middle schools in Isfahan, Iran. Materials and Methods This investigation performed from February 2016 to July 2016, thoroughly, 1191 Junior high school children aged 13-14 years old were screened in our study. Authenticated ISAAC questionnaire was interviewer-administered to gather data on parentally informed symptoms, clinician diagnoses and environmental exposures. Results: The students were averagely 13.57+ 0.5 years old; 779 (65.4%) of them had been suffering from AR and 696 (58.4%) of them had the symptoms of rhinitis over the preceding year. Symptoms of conjunctivitis such as Itch and watery eyes have been reported in 35.1% of cases. Among examined students, 644/1191 (54.1%) were females (P= 0.000). The relationship of allergic rhinitis and exposure to parental smoking, domestic and type of feeding in infancy were not significant (P= 0.655, 0.459, 0.946, respectively), but exposure to house planting was statistically significant (P=0.000). Daily activity was affected in 43(3.6%). Conclusion Prevalence of allergic rhinitis was considerably high in Junior high school students of Isfahan and frequently is undiagnosed. In addition the association of allergic with gender and keeping house plants was significant.

Incidence of and Factors Associated With Myopia and High Myopia in Chinese Children, Based on Refraction Without Cycloplegia

Myopia has reached epidemic levels among children in regions of East and Southeast Asia. High myopia is associated with myopic macular degeneration, glaucoma, and retinal detachment. To determine the incidence of myopia and high myopia based on refraction without cycloplegia among children in primary and junior high schools in China. This observational cohort study was completed in Guangzhou, China. It consisted of a cohort from 19 primary schools, who were followed up from 2010 to 2015, and a cohort from 22 junior high schools, who were followed up from 2010 to 2012. All schools were randomly chosen at rates proportional to the number of schools in each of the city's 11 districts. Students with or without myopia in grade 1 (primary school) or grade 7 (junior high school) were eligible for inclusion. Data analysis occurred from February 2017 to October 2017. Myopia was defined as a spherical equivalent refraction (SER) of -0.50 diopters (D) or less, as measured by subjective refraction without cycloplegia; high myopia was defined as a SER of -6.0 D or less. Annual incidences were defined as the proportion of participants each year found to have myopia or high myopia who did not previously have the condition. Height, weight, axial length (AL), corneal radius of curvature (CRC), and AL/CRC ratio were examined to assess if these measures were associated with future myopia or high myopia. A total of 4741 students with or without myopia in either grade 1 for the primary school cohort (mean [SD] age 7.2 [0.4] years; 932 of 1975 [47.2%] female) or grade 7 for the junior high school cohort (mean [SD] age 13.2 [0.5] years; 1254 of 2670 [47.0%] female) were included. Baseline mean (SD) SER was 0.31 (0.86) D among 1975 students in grade 1 vs -1.60 (2.00) D among 2670 students in grade 7. Baseline prevalence of myopia was 12.0% in grade 1 students (n = 237 of 1969) and 67.4% in grade 7 students (n = 1795 of 2663). The incidence of myopia was 20% to 30% each year throughout both cohorts. The incidence of high myopia was initially less than 1% in the primary school cohort (grade 1: n = 2 of 1825; 0.1% [95% CI, 0.0%-0.3%]), but incidence exceeded 2% in the junior high school cohort (in grade 9: n = 48 of 2044; 2.3% [95% CI, 1.0%-3.7%]). The incidence of myopia among Chinese students based on refraction without cycloplegia is among the highest of any cultural or ethnic group. If confirmed with cycloplegic refraction, interventions to prevent myopia onset in Chinese populations should be initiated in primary schools.

An independent relation of atopic dermatitis to exercise-induced wheezing in asthmatic children

BackgroundAtopic dermatitis (AD) and exercise-induced asthma (EIA) are common in asthmatic children, and exercise is the most common trigger other than infection for acute onset asthma attack in children. We examined whether AD is related to exercise-induced wheezing (EIW), some proxy for EIA. MethodsJapanese version of the International Study of Asthma and Allergies in Childhood questionnaires were used. For 12,405 asthmatic school children, AD was defined as itchy rash coming and going for at least 6 months at any time in the last 12 months with affecting places of flexural parts of body, and severity of AD was rated according to frequency of being kept awake at night with the itch as follows: never in the past 12 months, less than one night per week and one or more nights per week. ResultsAdjusted for frequency of asthma attack, odds ratios (OR) of children with current AD as compared to those without AD for having EIW were 1.32 (95% confidence interval = 1.15–1.52), 1.35 (1.14–1.68) and 1.10 (0.92–1.31) for primary school, junior high school and high school children, respectively. EIW was more likely observed in accordance with increasing severity of AD in the primary school children with ORs of 1.12, 1.59 and 1.54 (p for trend < 0.01), and in the junior high school ones with ORs of 1.18, 1.31, 2.03 (<0.01), respectively. ConclusionsAD may be possibly related to EIW. Further studies investigating effect of AD treatment on EIW may be required.

Prevalence and risk factors of halitosis in Japanese school children.

Little data are available regarding halitosis in Japanese children. The aim of the current study was to investigate the prevalence and risk factors associated with halitosis in Japanese elementary and junior high school children. The subjects consisted of 520 elementary (1st-6th grade: boys, n = 284; girls, n = 236) and 248 junior high (7th-9th grade: boys, n = 136; girls, n = 112) school children aged 6-15 years in Saitama Prefecture, Japan. A self-administered questionnaire survey; halitosis measurement using an organoleptic assessment method; and clinical oral examination were conducted. Overall, 44.9% of subjects had halitosis. The proportion of boys with halitosis was 43.6% and that of girls was 46.6%. On logistic regression analysis, grade and tongue coating were significant predictors of halitosis. The 7th-9th graders were significantly more likely to have halitosis than 1st-3rd graders (OR, 1.83; P = 0.007). Subjects with area of tongue coating score 2 or 3 were 5.51-fold more likely to present with halitosis (P < 0.001) than those with area of tongue coating score 0 or 1. Similarly, subjects with thickness of tongue coating score 2 or 3 were 3.28-fold more likely to have halitosis than those with thickness of tongue coating score 0 or 1 (P < 0.001). Halitosis in the school children is not a rare condition; instead, its occurrence is relatively high. Therefore, inclusion of a halitosis prevention and management component in school oral health programs would lead to the promotion of overall oral health.

A National Seroepidemiologic Survey of Pertussis Among School Children in Taiwan.

In 2009, a booster dose of acellular pertussis vaccine for children at or before entry to elementary school was added to the national immunization program in Taiwan, which includes pertussis vaccination at 2, 4, 6 and 18 months of age. In 2013, a study to assess the level of humoral immunity against pertussis in elementary and junior high school children and adolescents was conducted. A multistage stratified systematic sampling method was applied to randomly selected grade 1 to 9 school children for testing. Serum samples were tested for IgG antibodies to Bordetella pertussis using commercial enzyme-linked immunosorbent assay kits. The study collected information on sociodemographic characteristics, vaccination history, sibling number and disease history of pertussis. The study recruited 2782 school children from 58 schools around the country. By questionnaire, only 1% (28/2782) students had history of pertussis. The overall positivity rate of anti-B. pertussis IgG was 42.5%, and the rates were not different between the 5 geographical areas (range from 39.6% to 44.6%, P = 0.375). Age-stratified data showed that the positivity rates were 43.6-48.8% among grade 1-3 students, 26.6-28.7% in grade 4-5 students and increased progressively from 39.4% to 51.3% in grade 6-9 students. The overall positivity rate was significantly higher in the nonbooster group (46.4% versus 38.6%, P < 0.01). The prevalence of anti-B. pertussis antibody was 42.5% in grade 1-9 students under the current vaccination program in Taiwan. Antibody induced by the booster vaccination before entry of primary school waned rapidly in 3-4 years. Rapid waning of anti-B. pertussis antibody may explain the resurgence of whooping cough in recent decades. Additional booster doses should be considered in adolescents and adults.

SFA intake among Japanese schoolchildren: current status and possible intervention to prevent excess intake.

Although a high intake of fat, particularly SFA, is a well-known risk factor for CVD, fat intake in Japan has attracted relatively little attention from health professionals to date due to the low intake in the Japanese population. However, recent surveys have shown an increase in fat intake in younger Japanese populations. Here, we described the fat intake and dietary sources of SFA in Japanese schoolchildren. Also, we experimentally exchanged a high-SFA food with a low-SFA substitute in the data, and calculated the resulting changes in nutrient intakes. The study was conducted nationwide under a cross-sectional design. A non-consecutive, three-day diet record was performed on two school days and a non-school day. Fourteen elementary and thirteen junior high schools. Elementary-school children (n 629) and junior high-school children (n 281). Prevalence of excess fat intake was 35·4 % in boys and 45·0 % in girls. Excess SFA intake was suspected in 97·7 % of boys and 99·4 % of girls when the dietary reference intake values for adults were applied. Major dietary sources of SFA were meat (26·4 % of total SFA intake), dairy products (25·7 %) and confectioneries (11·3 %). Since one-third to nearly one-half of our Japanese schoolchildren consumed excess fat, careful monitoring of fat intake in the Japanese population should be continued. Adoption of low-fat milk and/or lean meat in daily meals might be a suitable means of reducing fat, particularly SFA intake, in schoolchildren.

&lt;p&gt;&lt;em&gt;Humans are born into the world by having three intelligences, namely spiritual intelligence, emotional intelligence and intellectual intelligence. Spiritual intelligence is the highest intelligence that combines both forms of intelligence, namely intellectual intelligence and emotional intelligence. A person's spiritual intelligence will be high if the level of education and parenting patterns of a person is also good.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;This study aims to describe the level of education and parental parenting to the spiritual intelligence of Junior High School children in Mengwi Subdistrict. In addition to knowing whether or not the relationship of each variable.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;The approach used in this study is quantitative with correlational causal design, in this study to determine the causal relationship of the emphasis on the correlated variables. The variables studied are one dependent variable that is spiritual intelligence (Y) and two independent variables, namely the level of parent education (X1) and parenting parents (X2). The population in this study is all students of class VIII of Junior High School in Mengwi Subdistrict which is Hinduism is 1,983 students. Determination of the size of the sample using a formula formulated by William G. Chocran who get the number of samples of 180 students who can represent the population with proportional sampling area techniques where the take by taking into account the number of existing population in each school. Technique of collecting data using instrument in the form of questionnaires to capture the data of three variables are: (1) spiritual intelligence, (2) parental education level and (3) parenting pattern.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;The result of research shows: (1) there is correlation between parent education level to spiritual intelligence with correlation value 0,361 and significance level equal to 0,05, (2) there is relation between parenting parenting to spiritual intelligence with correlation value 0,358 and Significance of 0,05 and (3) there is correlation between educational level and parenting pattern to spiritual intelligence with correlation value of 0,365 and significance level equal to 0,05.&lt;/em&gt;&lt;/p&gt;

Physical activity among Chinese school-aged children: National prevalence estimates from the 2016 Physical Activity and Fitness in China—The Youth Study

PurposeThis study was to present national estimates of participating in moderate-to-vigorous physical activity (MVPA) and adherence to the recommendations of 60 min/day of MVPA among Chinese school-aged children and to assess demographic differences in MVPA. MethodsCross-sectional analyses of data from the 2016 Physical Activity and Fitness in China—The Youth Study. Participants were 90,712 primary, junior middle, and junior high school children (boy: 47%; girl: 53%), recruited from 1204 rural and urban schools across 32 administrative provinces and regions in the Mainland of China. Main outcomes were (a) average MVPA minutes per day in the previous 7 days by self-reports and (b) percentage meeting MVPA recommendations. ResultsAverage MVPA time was 45.4 min/day, with boys having more MVPA (47.2 min/day) than girls (43.7 min/day) overall and across the 3 school grade categories. About 30% of participants met MVPA recommendations, with a higher percentage of boys (32%) than girls (28%) overall and across the 3 grades categories. Urban school children outperformed rural children in terms of MVPA time. Overall, boys were more likely to meet MVPA recommendations (adjusted odds ratio (aOR) = 1.19, 95% confidence interval (CI): 1.16–1.22) compared with girls; children in higher grades (junior middle (aOR = 0.92, 95%CI: 0.87–0.98) and junior high (aOR = 0.59, 95%CI: 0.53–0.66)) were less likely to meet recommendations compared with primary school children. The odds of meeting recommendations did not differ between urban and rural children (p = 0.07), but urban boys were found to be more likely to meet recommendations compared with rural boys (aOR = 1.14, 95%CI: 1.06–1.19). ConclusionOverall, the average MVPA minutes per day among Chinese school-aged children is low, and less than one-third of them meet MVPA recommendations. These results were most evident among junior middle and junior high school children and those living rural areas.

Overweight, obesity, and screen-time viewing among Chinese school-aged children: National prevalence estimates from the 2016 Physical Activity and Fitness in China—The Youth Study

PurposeThis study presents the most recent estimates of prevalence of overweight, obesity, and screen-time viewing among Chinese school-aged children. Demographic differences in these estimates between sexes and resident locales were also examined. MethodsCross-sectional analyses of 116,615 Chinese school children 9 to 17 years of age who participated in the 2016 Physical Activity and Fitness in China—The Youth Study project. Outcomes were the prevalence of children's overweight (85th ≤ body mass index (BMI) < 95th percentile) and obesity (BMI ≥95th percentile) (defined by the Working Group on Obesity in China) and not meeting screen-time viewing recommendations (“not meeting” was defined as more than 2 h per day of viewing activities after school). Analyses were conducted on the whole sample and by school grade cohorts (primary, junior middle, and junior high schools), sex, and residence locales (urban, rural). ResultsOverall, 14.4% (95% confidence interval (CI): 13.8%–15.0%) of children and adolescents were overweight, 11.9% (95%CI: 11.0%–13.0%) were obese, and 36.8% (95%CI: 34.7%–38.9%) did not meet screen-time viewing recommendations. Across the 3-grade cohorts, boys were more likely to be obese than girls, and primary and junior middle school children living in urban areas were more likely to be obese than those living in rural areas. Primary and junior middle school boys were less likely to meet screen-time recommendations than girls, and junior high school children living in urban areas were less likely to meet screen-time recommendations than school children of the same grades living in rural areas. ConclusionIn 2016, the prevalence of obesity among Chinese school children was about 12%, and about 37% of them did not meet screen-time viewing recommendations. The prevalence of obesity and sedentary behavior was generally higher among boys than among girls, and it was higher for children living in urban areas than for those living in rural areas.
