ObjectiveTo assess the level of depression， anxiety and social support among grade three senior high school students under in-school quarantine during the COVID-19 pandemic， so as to provide references for targeted psychological intervention of them. MethodsA total of 724 grade three senior high school students from three key schools in Binzhou City， Shandong Province were selected using random sampling method. Generalized Anxiety Disorder （GAD-7）， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9） and Perceived Social Support Scale （PSSS） were used to survey the psychological status including anxiety， depression and the level of social support. Partial correlation analysis was adopted to discuss the correlation of PSSS score with GAD-7 and PHQ-9 scores， meantime， the multiple linear regression analysis was conducted to explore the relationship between PSSS and PHQ-9 scores. ResultsAmong grade three senior high school students， 341 （48.64%） and 383 （54.64%） were found to have symptoms of anxiety and depression， respectively. PSSS total score as well as the dimension score of family support and other support of female students were higher than those of male students， with statistical significance （t=-3.431， -3.048， -4.482， P<0.01）. GAD-7， PSSS total scores and the dimension scores of family support and other support demonstrated statistical differences among grade three senior high school students with different selections of academic subjects for college entrance examination （F=1.992， 2.660， 2.074， 3.138， P<0.05 or 0.01）. PHQ-9 score was negatively correlated with the total score and each dimension score of PSSS （r=-0.329， -0.283， -0.284， -0.284， P<0.01）. The dimension score of family support and friend support in PSSS could negatively predict the PHQ-9 score （B=-0.213， -0.308， P<0.01）. ConclusionGrade three senior high school students under in-school quarantine during the COVID-19 pandemic suffer a high prevalence rate of anxiety and depression， while students with higher perceived social support scores report fewer symptoms of depression. Hence， improving the level of social support may alleviate depression in students.

Sexual and reproductive health knowledge and practice among students in six senior high schools in three regions in East China / 上海预防医学

Objective:To know the status of knowledge， attitude and behavior related to sexual and reproductive health in high school students in three regions of East China， and to provide a reference for adolescent reproductive health education. Methods:From August to October in 2019， 614 high school students were invited from 6 high schools in Jiading District and Yangpu District， Shanghai and Taicang City， Jiangsu to participate in this study. We conducted an anonymous self-questionnaire survey using structured questionnaires based on adolescent reproductive health knowledge and literacy. Results:The male to female ratio of all high school students in the study was 1∶1.25， and the average age was （16.1±0.9） years old. The score of pregnancy and abortion knowledge was the lowest among the reproductive health knowledge scores， and the differences among the three regions were statistically significant （P=0.002）. Male high school students （P<0.001）， students in the school with reproductive health education base （P=0.008） and students who wanted to obtain reproductive health education （P=0.002） were more acceptable to premarital sex. The high school students obtained adolescent health knowledge mainly through the internet or mobile phones， and had a demand for reproductive health related services. Conclusion:High school students in the three regions have a more open attitude towards premarital sex， but have a poor grasp of correct and efficient contraceptive knowledge. Responsible departments need to strengthen the health education of relevant knowledge， and at the same time to find new forms of education to effectively improve the level of adolescent reproductive health.

Development of Dietary Schedule for Improved Nutritional Support during Training Period of Junior & Senior High School Fencers in Ulsan City

This study was conducted in order to improve nutritional support based on analysis of the eating habits and training schedule of junior and senior high school fencers. A survey was conducted on 30 fencers (junior boys=9, girls=7; senior boys=4, girls=10) using a questionnaire. Total daily calorie intakes were 2325.7+/-1168.5 kcal (boy), 2344.0+/-786.3 kcal (girl) for junior fencers and 2183.3+/-726.6 kcal (boys), 2654.4+/-1043.6 kcal (girls) for senior fencers. Nutrients below the RDIs were riboflavin and vitamin C for junior boy fencers and vitamin A, riboflavin, niacin, and vitamin C for senior boy fencers. The rates of the participants who had obtained nutritional information were 44.4% (boys) and 14.3% (girls) for junior fencers and 50.0% (boys) and 80.0% (girls) for senior fencers. Approximately half of the fencers had meals twice a day (55.6% for junior boy fencers, 57.1% for junior girl fencers, and 50.0% for senior fencers). The number of the fencers who were interested in nutrition varied: 66.7% and 28.6% of the junior boy and girl fencers answered they were interested in nutrition, while 25% and 60% of the senior boy and girl fencers showed interest in nutrition issues. Recommendations of total calories were 2,874 kcal (boys) and 2,377 kcal (girls) for junior fencers and 3,398 kcal (boys) and 2,375 kcal (girls) for senior fencers respectively. A dietary plan for the fencing players during training periods was designed to improve their health and performance. Athletes can simultaneously refuel and repair their bodies while contributing to their rehydration goals by consuming fluids that are sources of carbohydrates and protein, e.g., flavored milk and liquid meal supplement. Specific sport nutrition education applicable to athletes, especially young athletes, is recommended under professional support. Professionals may then target particular categories of athletes for the development of educational programs aimed at improving growth and athletic performance.

Indicadores conductuales de ansiedad escolar en bachilleres en función de sus calificaciones en un examen de matemáticas / Behavioral Indexes of Test Anxiety in Mathematics among Senior High School Students

El estudio de las matemáticas ha sido y es aún una fuente de frustración y ansiedad para un número considerable de estudiantes. No obstante, se considera como una piedra angular en la formación escolar, por el énfasis que hace en el entrenamiento analítico y en el manejo del lenguaje simbólico. El propósito del presente estudio fue valorar los niveles de ansiedad, vía procedimientos conductuales y fisiológicos antes y después de la administración de un examen de matemáticas en el bachillerato y analizar la relación que guardan éstos con el desempeño en el examen, en el curso y en el promedio semestral. Las preocupaciones escolares fueron evaluadas mediante una prueba computarizada basada en la versión emocional del paradigma de Stroop, diseñada ex profeso para medir la ansiedad escolar, que consistió en una tarea de discriminación condicional que empleaba palabras con carga negativa o neutra (Hernández-Pozo, Macías & Torres, 2004). Esta prueba se administró antes y después del primer examen de matemáticas del curso. Se monitoreó la tensión arterial, antes y después de cada exposición a la prueba de Stroop. Participaron en el estudio 205 bachilleres. El desempeño académico global guardó una relación inversa con el nivel de ansiedad conductual. Los resultados contradictorios entre el desempeño en matemáticas y el promedio general, así como la ausencia de diferencias por género en ansiedad medida conductualmente, cuestionan la generalidad de aseveraciones que relacionan de manera inversa el desempeño académico con los niveles de ansiedad de los bachilleres.

The study of Mathematics has been and is still a source of frustration and anxiety for a large number of students. The purpose of this study was to inquire systematically upon levels of test anxiety through behavioral and physiological procedures before and after a Math test, in 205 senior high school students. Academic worries were assessed by means of a computerized task based on the emotional version of the Stroop paradigm designed ex profeso to measure school anxiety (Hernández-Pozo, Macías & Torres, 2004). The Stroop task was administered, along with recordings of blood pressure and pulse, before and after the first Math test of the course. Academic general scores were inverse to the behavioral anxiety level, however the best Math scores were associated to middle levels of behavioral anxiety. Contradictory findings between academic performance in Math and global score, and the apparent lack of gender difference in anxiety measured through behavioral procedures suggests the need to review the generality of previous assertions relating academic performance inversely with levels of anxiety of high school students.

Research on Relationship Between Tendency to Computer Game addiction and Parental Rearing Styles in Senior High School Students / 中国临床心理学杂志

Objective: The purpose of this research is to investigate the relationship between computer game addiction,a subtype of internet addiction,and parental Rearing styles.Methods: Using Computer Game Addiction Inventory(CGAI) and EMBU,we investigate a sample of 747 senior high school students in Beijing.According to whether participants' sum score of five dimensions of CGAI is larger than 1.5 SD,we divide them into two groups: tendency to addiction and non-tendency to addiction.Then we analyze the data with methods of MANOVA and Canonical Correlation.Results: There is significant difference in sex distributing between tendency to addiction and non-tendency to addiction.There is also significant difference in parental rearing styles between two groups.Under authoritarian rearing styles,children score higher on nearly every dimension of CGAI.Conclusion: Boys are more likely to get addicted to computer games than girls.Negative parental rearing styles associate closely with computer game addiction.

Effectiveness of Web-Based Nutritional Education Program for Junior and Senior High School Students

The purpose of this study was to evaluate the effects of Web-based nutrition education program for junior and senior high school students. Three materials, which were printed materials on Group I, WBI (Web-Based Instruction) leaflet on Group II and the web-based nutrition education program developed in the antecedent research, were applied for 564 students in 3 junior high school and 4 senior high school in Seoul during 4 weeks. Pre-test was done from October 21 to October 26, 2002 and post-test was done from November 25 to December 13, 2002. The statistical data analysis was completed using SPSS WIN (ver. 11.0) for descriptive analysis, t-test and ANOVA. According to the evaluation of effectiveness for web-based nutrition education program, nutrition knowledge, food attitude, food habit and nutrient intake were not significantly improved but positively. And on the evaluation of effectiveness for nutrition education program by materials, WBI was more effective educational materials than WBI leaflet and printed materials. Consequently nutrition knowledge, food attitude, food habit and nutrient intake were improved positively but not significantly using WBI, which was due to the instructional period of the only 4 weeks. Therefore long-term instruction should be required for effective nutrition program, as well as more WBI nutrition education program for high school students would need to be developed in the near future in that WBI was effective material on nutrition education.

Identifying the Subjects of Nutrition Education for Junior and Senior High School Students

The purposes of this study were to survey the present situation of nutrition education in junior/senior high school, to analyze the difference between the favorite subjects on students and the existing subject done by dietitians on nutrition education, and then to identify the subjects of nutritional education for junior/senior high school students. Self-administered questionnaires were given to dietitians and students and 142 of the 200 dietitians (71.0%) and 479 of the 564 students (84.9%) responded to the questionnaire on the nutritional education. According to the survey results, 76.1% of school dietitians currently were doing nutrition education for students while the other 23.9% didn't have such education programs even though they recognized the necessity strongly. The target of nutrition education was student rather than parents or teacher generally and the principal measuring method for nutrition education effect was 'change of plate waste and leftover'. It was found that significant difference in the collector and source of nutritional education information between junior and senior high school dietitians (p < .05). About ninety-eight percentage of dietitians felt that nutrition education should keep pace with meal service and this meant that almost respondent recognized the necessity of nutrition education for students. Because the most serious one among operational problems of nutrition education program was lack of enough time owing to too many affairs as dietitian, junior and senior high schools should support so that dietitians would share enough time for nutrition education. And also, a gap was existed between actual and favorite subjects on nutrition education. Significant differences existed in the following subjects; 'basic concept of food and nutrition', 'disease and nutrition', 'food culture in the world', 'cooking and culinary art', 'food of the 24 divisions of the year in the lunar calendar', 'food waste and environmental issue', 'food habit and food behavior', 'exercise and nutrition' (p < .001), 'table manner', 'food and individual sanitation', 'recommended dietary allowance' (p < .01) and 'menu planning' (p < .05). Finally, 24 subjects of nutritional education were selected based on the survey results. These subjects would be expected to be able to contribute the effective and interesting nutrition education program for junior and senior high school students.
