Current situation of screen time among Chinese primary and middle school students from 2016 to 2017

To get a better knowledge of the current situation of screen time among primary and secondary school students in all provinces of China from 2016 to 2017. Data was from the China National Nutrition and Health Surveillance of Children and Lactating Women(2016-2017).275 monitoring points were selected from 31 provinces of China by multi-stage stratified cluster random sampling. A total of 280 primary and secondary school students from 2 primary schools, 2 junior middle schools and 1 senior high school were randomly selected from each monitoring point to complete the survey.73629 primary and secondary school students(except grade 9 and grade 12) were included in this study. From 2016 to 2017, the average daily screen time of Chinese primary and secondary school students was(1.65±1.54) hours, M(P25, P75) was 1.29(0.58, 2.21) h. In terms of provinces, the average daily electronic screen time of primary and secondary school students in Beijing, Tianjin, Jilin, Fujian, Guangdong and Hainan is more than 2 hours. In terms of rural and urban areas, the screen time of students in Beijing's rural and urban areas, Tianjin's rural areas, Hebei's urban areas, Liaoning's rural areas, Jilin's rural areas, Fujian's urban areas, Guangdong's urban areas, Guangxi's urban areas, Hainan's rural and urban areas, and Xinjiang's urban areas all exceeds 2 hours/day. Besides, screen times of rural primary and secondary school students in Beijing(Z=2.62, P<0.01), Tianjin(Z=5.94, P<0.01), Liaoning(Z=11.56, P<0.01), Jilin(Z=-7.59, P<0.01), Shanghai(Z=3.19, P<0.01), Jiangsu(Z=12.00, P<0.01), Zhejiang(Z=-4.80, P<0.01), Anhui(Z=-4.67, P<0.01), Jiangxi(Z=-3.29, P=0.01), and Sichuan(Z=-4.53, P<0.01) are longer than that of urban students. There are urban-rural differences in the average daily electronic screen time and different types of electronic screen time of primary and secondary school students in China's provinces from 2016 to 2017.

This study used a quasi-experimental design to investigate the impact of Rapid Reading Skills Training (RRST) on some reading outcomes for primary school students in central China and also examined the influence of cognitive flexibility on intervention outcomes. A sample of 108 students (mean age = 11.75 years) were recruited. Students' cognitive flexibility was measured with the Wisconsin Card Sorting Task. Cluster randomization was used to assign students at the whole class level to either an experimental or control condition. A 12-session RRST intervention was completed with the experimental class ( N = 54). Silent reading speed and passage comprehension were measured before and after training for all students. Independent samples t-tests and two-factor repeated measures ANOVA revealed that students in the experimental class displayed higher scores for reading speed and effective reading rate post-intervention than those in the control class. Students who had scored higher on cognitive flexibility showed significantly larger increases post-intervention than those scored lower. Results provide preliminary support for using RRST to increase rapid silent reading speed among Chinese primary school students, though replication and more rigorous experimental designs are needed. Cognitive flexibility may enhance gains associated with this type of intervention. Implications for school psychologists are discussed.

Objective To understand the prevalence and trend of the poor eyesight in primary and middle school students in Beijing, and to provide theoretical basis for eyesight protection and myopia prevention and control. Methods According to “Technical Standard for Student Health Inspection” (GB/T 26343–2010), students were examined with a standard logarithmic visual acuity E chart for naked eye vision. Results The prevalence of poor eyesight among primary and middle school students in 2010-2016 was 63.0%, 62.1%, 62.9%, 60.7%, 59.2% and 58.6% respectively, decreased by 7.0% in 6 years, primary school students dropped by 9.7%, and junior school students, senior high school students and vocational high school students increased by 5.5%, 3.3% and 14.1% respectively. Urban and suburban areas (61.2%, 54.3%) decreased by 9.6% and 2.9% respectively. Regardless of boys and girls, urban and suburb, between 2010 and 2016, the overall composition ratio of students in each school segment was expressed as primary school > junior school > senior high school students > vocational high school, and vocational high school students accounted for the minimum; the overall composition ratio of primary school has become more and more large. Conclusion Eyesight protection and myopia prevention among primary and middle school students in Beijing is still challenging. All departments should take active and effective measures to control the newly onset and progression of low vision and improve eyesight. 【摘要】 目的 了解北京市中小学生视力不良检出率及变化趋势, 为学生视力保护及近视防控提供参考依据。 方法 按照《学生健康检査技术规范》 (GB/T 26343—2010), 采用标准对数视力表对北京市全体中小学生进行裸眼远视力检査。 结果 2010—2016 年北京市中小学生视力不良检出率分别为 63.0%, 62.1%, 62.9%, 60.7%, 59.2% 和 58.6%, 6 年间下降了 7.0%。2015—2016 年小学生、初中生、普通髙中生、职业髙中生视力不良检出率分别为 45.5%, 78.4%, 89.4%和74.5%, 较 2010—2011 年小学生下降了 9.7%, 初中生、普通髙中生和职业髙中生分别增长了 5.5%, 3.3% 和 14.1%; 2015—2016 年, 城 区、郊区学生视力不良检出率分别为 61.2% 和 54.3%, 较 2010—2011 年分别下降了 9.6% 和 2.9%。不论男生、女生, 城区、 郊区, 2010—2016 年, 每年各学段学生总体构成比均表现为小学>初中>普通髙中>职业髙中, 职业髙中学生占比最小; 随着 年份的增加, 小学的构成比增大。 结论 北京市中小学生视力不良防控工作任务艰巨。各部门应采取积极有效的措施, 控 制视力不良新发和加重, 提髙中小学生视力健康水平。

Objective: To investigate the prevalence of dyslipidemia, and to explore the association between extracurricular physical activity and dyslipidemia among primary, middle and high school students in Guangzhou. Methods: This cross-sectional study selected primary and middle school students in Guangzhou by the stratified cluster sampling method from March to December 2019. Physical examination and blood lipid test were performed. Information about students' basic characteristics and extracurricular physical activity was collected by questionnaire. Multivariate logistic regression analysis was used to determine the association between extracurricular physical activity and dyslipidemia in this cohort. Results: A total of 7 797 participants (mean aged (12.2±2.9) years) were included (4 194 (53.79%) boys and 3 603 (46.21%) girls]. The detection rates of high total cholesterol, high triglycerides, low high-density lipoprotein cholesterol, high low-density lipoprotein cholesterol and dyslipidemia were 12.49% (974/7 797), 6.44% (502/7 797), 6.62% (516/7 797), 11.31% (882/7 797) and 23.83% (1 858/7 797), respectively. Dyslipidemia rate was lower in the junior school students (21.39% (675/3 156)) than in primary school students (25.96% (896/3 451)) and high-school students (24.12% (287/1 190)) (P<0.001). The dyslipidemia rates of boys and girls were similar (23.15% (971/4 194) vs. 24.62% (887/3 603), P>0.05). Dyslipidemia rate was lower in students with extracurricular physical activity than in students without extracurricular physical activity (22.50% (923/4 102) vs. 25.30% (935/3 695), P<0.05). Multivariate logistic regression analysis showed that extracurricular physical activity was associated with lower risk of dyslipidemia (OR=0.88, 95%CI=0.79-0.99, P=0.033). Among all types of extracurricular physical activities, participating in extracurricular large ball game was associated with 28% lower risk among junior school students (OR=0.72, 95%CI=0.57-0.91, P=0.006). Conclusion: The prevalence of dyslipidemia is high among primary, middle and high school students in Guangzhou. Extracurricular physical activity is associated with reduced risk of dyslipidemia in this cohort.

ObjectivesPrioritizing adolescent idiopathic scoliosis (AIS) prevention over treatment is crucial, especially in countries like China where students are heavily focused on academics. Little research combines the educational characteristics of junior and senior high school students in China to explore factors contributing to AIS. Our aim was to investigate the correlation between performance indicators and potential AIS determine differences between junior and senior high school students.MethodWe conducted a general investigation of potential AIS-related indicators in students attending a comprehensive school in the Yunnan Province. In total, 264 junior high school students and 501 senior high school students were surveyed. Both subjective and objective performance indicators as well as additional factors, such as extracurricular activities and schoolbag-related factors, were considered. The reliability and validity of the questionnaire were assessed, and all items pertaining to performance and other relevant factors were analyzed.ResultsThe proportion of senior high school students with a trunk rotation angle > 7° was higher than that of junior high school students (5.59% vs. 2.27%). Junior high school students were more affected by the weight of their schoolbags than senior high school students (35.98% vs. 27.74%). In contrast, senior high school students had more abnormal postures than junior high school students (28.03% vs. 38.32%). The frequency of extracurricular activities was significantly lower in senior high school students than in junior high school students, particularly among students with a trunk rotation angle of > 5° or > 7°. The questionnaire results indicated that the survey model was suitable. Significant correlations were found between schoolbag-related issues, growth-related concerns, abnormal posture, and abnormal lifestyle. Abnormal lifestyle was found to have a potential impact on abnormal sensations, whereas abnormal pain was influenced by abnormal posture, lifestyle, and sensation.ConclusionsOur questionnaire captured the distinct attributes of junior and senior high school students in a Chinese province regarding potential Adolescent Idiopathic Scoliosis (AIS). Junior high school students are more affected by schoolbag weight, while senior high school students exhibit more abnormal postures. The frequency of extracurricular activities shows an inverse relationship with both heavy schoolbag weight and abnormal postures. Increasing the frequency of extracurricular activities and addressing abnormal habits may help prevent the onset of AIS in students experiencing high levels of academic stress.

<p id="p00005">In recent years, the age of mental health problems shows a descending trend. Primary school students, as a special group in the critical stage of personal growth, are experiencing increased mental health problems that has caught wide attention from society. If the mental health problems of primary school students are not screened, prevented, and intervened in time, they may develop into lifelong mental diseases, which are difficult to redress and treat. Hence, as the basic premise of improving mental health, it is particularly important to find out the prevalence of pupils' mental health problems, so as to understand their real mental health status, and make targeted detection and intervention in the future. <br/>However, the prevalence of primary school students' mental health problems described in literature shows inconsistent results, and the prevalence varied greatly, which has brought confusion to mental health educators and workers. Although some researchers tried to use meta-analysis to quantitatively integrate the existing research findings, avoid the influence of biased samples, demographic characteristics, and other factors, and attempt to explore the detection rate of primary school students’ mental health problems objectively and accurately, there were still some deficiencies. Firstly, it only revealed the prevalence of some mental health problems, and did not cover more comprehensive mental health problems. Secondly, it did not specifically analyze the mental health problems in recent 10 years. Finally, the inclusion and discussion of regulatory variables were not specific enough. Therefore, based on the research results in recent 10 years, it is necessary to integrate the prevalence of primary school students' mental health problems and explore its influencing factors by using meta-analysis method. <br/>In order to clarify the debate on the different prevalence of primary school students' mental health problems, we analyzed and estimated the detection rate of primary school students' mental health problems in mainland China from 2010 to 2020 and investigated its moderation effects. The meta-analysis technology was used to retrieve the research on anxiety, depression, somatization, withdrawal, sleep problems, aggressive and discipline behaviors in Chinese National Knowledge Infrastructure database and Web of Science core collection database from 2010 to 2020. Finally, a total of 101 research and 289396 primary school students were obtained: 9 articles about anxiety, 34 articles about depression, 12 articles about somatization, 10 articles about withdrawal, 11 articles about sleep problems, 13 articles about aggressive behavior, and 12 articles about disciplinary behavior. The software Comprehensive Meta-Analysis Version 3.3 and the random effect model was selected for analysis.The results showed that (1) The prevalence of mental health problems in primary school students from high to low were sleep problems (25.2%, 95%CI = [0.16, 0.37]), depression (14.6%, 95%CI = [0.12, 0.18]), anxiety (12.3%, 95%CI = [0.06, 0.23]), aggressive behavior (4.1%, 95%CI = [0.02, 0.10]), withdrawal (3.8%, 95%CI = [0.02, 0.06]), disciplinary behavior (3.7%, 95%CI = [0.02, 0.07]) and somatization (3.6%, 95%CI = [0.02, 0.07]); (2) Measurement tools, measurement standards and detection period were the key factors causing the fluctuation of prevalence of mental health problems among primary school students in China. Generally speaking, the overall mental health status of primary school students in China is acceptable except that the prevalence of sleep problems, depression and anxiety are high. In the future, we should develop mental health assessment tools and detection standards suitable for Chinese primary school students to provide support for the prevention and accurate intervention of mental health problems.

The prevalence of ocular diseases in primary and junior high school students on Orchid Island

The aim of this study was to investigate experimentation with smoking among primary school students in China. Data were acquired from a recent survey of 4,073 students in grades 4 to 6 (ages 9–12) in 11 primary schools of Ningbo City. The questions were adapted from the Global Youth Tobacco Survey (GYTS). Results suggest that although the Chinese Ministry of Education (MOE) encourages smoke-free schools, experimentation with cigarettes remains a serious problem among primary school students in China. Peers, family members, and the school environment play important roles in influencing smoking experimentation among students. Having a friend who smoked, seeing a family member smoke, and observing a teacher smoking on campus predicted a higher risk of experimentation with smoking; the exposure to anti-tobacco materials at school predicted a lower risk of experimentation with smoking. The evidence suggests that public health practitioners and policymakers should seek to ensure the implementation of smoke-free policies and that intervention should target young people, families, and communities to curb the commencement of smoking among children and adolescents in China.

The development of a Digital Intelligence Quotient (DQ) scale for primary school students is the basis for research on the DQ of primary school students, which helps to scientifically diagnose the level and the current average DQ among Chinese primary school students. This study developed and validated a scale applicable to the assessment of DQ in Chinese primary school students where, the initial scale was first constructed; Then 1109 valid datasets were collected through purposive sampling and divided into Sample A and Sample B; Sample A was subjected to exploratory factor analysis and Sample B was tested by confirmatory factor analysis; The final validated scale consists of 22 items in 7 dimensions: digital identity, digital use, digital safety, digital security, digital emotional intelligence, digital literacy and digital rights. The scale has high reliability and validity and thus can be used as a reliable instrument for assessing DQ in Chinese primary school students.

The aim of this study is to explore the basic situation of subjective well-being among primary and secondary school students and the relationship between academic achievement and subjective well-being. A questionnaire survey using the "Adolescent Student Life Satisfaction Scale" and the "Happy Feeling Scale" was conducted on 800 students from 6 high schools in Shanxi Province. The results of the study: (1) The subjective well-being of primary and secondary school students are at the upper-middle level. (2) The subjective well-being of female is generally higher than that of male, and the life satisfaction of primary school students is gender-specific. (3) There are grade differences in life satisfaction and positive emotions between primary school students and junior high school students. (4) The academic performance of primary school students and junior high school students was significantly positively correlated with life satisfaction, and negatively correlated with negative emotions. Research conclusions: Subjective well-being has a great influence on the academic performance of primary school students and junior high school students, and enhancing their subjective well-being is conducive to improving their academic performance.

Nowadays, it is widely acknowledged worldwide that music education is a beneficial activity for students’ cognitive, social, and emotional development (Ho, 2021). However, there is limited empirical evidence on how music education affects academic achievement in primary schools, especially in China. The aim of this literature review is to examine the existing research on the impact of music education on the academic achievement of primary school students in China, focusing on three aspects of music education: instrument-vocal training, music composition and music appreciation. The review synthesised the results of different research approaches and highlighted the importance of music education in enhancing Chinese primary school students’ motivation, creativity, and self-esteem, as well as in promoting cultural diversity and social harmony (Bao, 2020; Wang, 2021). Limitations of the current literature are then discussed and directions for future research are suggested, concluding that the main conclusion - that music education has a relatively positive impact on academic achievement in Chinese primary schools - requires more rigorous and comprehensive research to explore the underlying mechanisms and contextual factors that influence this relationship.
