Reliability and validity of the hidden hunger assessment scale in China-revised for high school students

Objective:Hidden hunger remains a severe public health problem that affects millions of people worldwide.In China,challenges related to dietary imbalance and hidden hunger persist.Micronutrient inadequacy deserves more attention among adolescents,given its vital role in their growth and development;however,this problem appears to have been largely ignored.High school students,in particular,are often at a high risk of hidden hunger but have limited assessment tools available.Therefore,this study aims to revise the hidden hunger assessment scale for high school students(HHAS-HSS)in China and assess its reliability and validity.Methods:Based on a literature review,expert consultation,pre-experiment,and formal survey,a hidden hunger assessment scale was revised for high school students.The formal survey involved 9336 high school students in 11 of the 16 cities in Anhui Province,China,and 9038 valid questionnaires were collected and included in the analysis.The item analysis,internal consistency reliability,test-retest reliability,content validity,exploratory factor analysis,and confirmatory factor analysis of the HHAS-HSS were examined.Results:The HHAS-HSS included a total of 4 dimensions and 12 items:"vegetables and food diversity"(three items),"fruits and dairy products"(three items),"micronutrient-dense foods"(four items),and"health condition and eating habits"(two items).The results showed a Cronbach's alpha of 0.758,a split-half reliability of 0.829,and a test-retest reliability of o.793,indicating good internal consistency.Using the Bartlett's test and Kaiser-Meyer-Olkin test(KMO)to test the exploratory factor analysis presented a four-factor model of the HHAS-HSS,the KMO0 value was 0.820(P<0.001),which indicated the possibility for factor confirmatory factor analysis.Using the maximum variance rotation method,four factors were obtained,and the cumulative variance explained rate was 57.974%.Confirmatory factor analysis also supported the division of the scale into four dimensions,and the fitting indices were x^(2)=1417.656,x^(2)/df=29.534,goodness-of-fit index=0.974,adjusted goodnessof-fit index=0.958,parsimonious goodness-of-fit index=0.600,normed fit index=0.938,incremental fit index=0.940,Tucker-Lewis index=0.917,comparative fit index=0.939,and root mean square error of approximation=0.056.Except for x^(2)/df,all the indices reached the fitting standard,and the above results showed that the construct validity of the scale reached an acceptable level.Conclusions:The HHAS-HSS has good validity and reliability for Chinese high school students.It is a convenient self-report measure of hidden hunger risk.

A Literature Review of Fertility Education for High School Students

Purpose: Fertility education for high school students leads them to be able to decide when to get pregnant and give birth, and to think about their desired life plan. However, knowledge of fertility in Japan is low compared to other countries. This study aims to understand the state of fertility knowledge among high school students in Japan and to clarify issues in fertility education. Method: Ten articles published from 2013 to July 2023 were selected for review from ICHUSHI Web Ver. 5 and CiNii with the keywords “high school students,” “fertility,” and “education.” The review was limited to Japanese-language literature due to differences in fertility education and knowledge between Japan and other countries. Results/Conclusion: 60% - 90% of the high school students indicated that their source of information on fertility was school lessons. Half of the students understood egg aging and the effects of smoking and drinking on fertility, but their knowledge of menstruation, male reproductive physiology/function, and infertility was insufficient. 50% - 80% of students wanted to marry by the age of 30, and 70% - 80% wanted to have children. 80% of students who attended a lecture on preconception care considered the lesson an opportunity to think about their future life plans. 90% of school nurse teachers reported that fertility should be taught in schools, and half said that egg aging, causes of infertility, and other topics should be covered in high school. Educational caution points included the consideration of developmental stages and the relatedness of the content to what had already been taught, among other things. High school is the best time for fertility education because it gives students the opportunity to accept their own sexuality and think about their future. In addition, since many students plan to marry and have children by the age of 30, the acquisition of fertility knowledge can be an effective means of future life design.

Effects of sports on school adaptability, resilience and cell phone addiction tendency of high school students

BACKGROUND Sport help promote healthy physical and mental development of high school students.To date,there have been few studies on the effect of sport on school adaptability,resilience and cell phone addiction tendency of high school students.AIM To explore the effects of sports on school adaptability,resilience and cell phone addiction of high school students.METHODS A stratified random sampling method was used to select 600 students from two high schools in Lhasa,and Physical Activity Rating Scale,School Adjustment Scale for High School Students,Chinese Adolescents Resilience Scale,and Mobile Phone Addiction Index were used for field questionnaire survey.RESULTS Sport was positively correlated with school adaptability and resilience(P<0.01),school adaptability was positively correlated with resilience(P<0.01)and cell phone addiction was negatively correlated with sports,school adaptability and resilience(P<0.01).The direct effect of sport on cell phone addiction was significant(P<0.001),accounting for 20.51%of the total effect.The mediating effect of school adaptability on sport and cell phone addiction was significant(P<0.001),accounting for 17.38%and 35.36%of the total effect value,respectively.School adjustment and resilience had a significant chain-mediated effect on sport and cell phone addiction(P<0.001),accounting for 26.75%of the total effect.CONCLUSION Sport affected the cell phone addiction tendency of senior high school students through the mediating effect of school adaptability and resilience,and through the chain mediation effect of both.

Primary Dysmenorrhea;Prevalence, Treatment Practices and Impact among High School Students in 2 Secondary Schools in Bafoussam

Background: Primary dysmenorrhea is defined as pelvic pain during menstrual flow in the absence of a pelvic pathology. It is one of the most common gynaecological complaints worldwide and the most common cause of school and work absenteeism among menstruating females. In adolescent students the impact includes reduced attention in class, inability to study at home, school absenteeism among others. Yet these students have to study at the same pace as their peers, raising the concern of whether the problems caused by primary dysmenorrhea have an effect on academic their academic performance. Aim: Determine the prevalence, treatment practices and impact of primary dysmenorrhea on the studies of post-pubertal high school students in Bafoussam. Method: We conducted a cross-sectional descriptive and analytic study design using a two-stage sampling method;the first stage was by convenience to choose the school, and the second stage was consecutive to recruit the students. Data was collected using a semi-structured pretested self-report and anonymous questionnaire. Analysis was done using software IBM®SPSS statistics version 23 for windows. Categorical variables were summarised in to frequencies and percentages while the comparison of categorical variables was done using a Chi-square test, and a p-value ≤ 0.05 was considered to be statistically significant. Results: our sample size was 898 and the mean age of our respondents (±SD) was 17.6 (±1.6) years. The prevalence of primary dysmenorrhea was 71.9%, with 11.6% mild pain, 52.5% moderate pain and 35.9% severe pain on a visual analogue scale. Over 38% did not attempt pain-relieving measures while others took analgesics, traditional preparations, heat packs among others. Among these students, 39% reported school absenteeism due to pain, other impacts were decreased attention in class, inability to study at home during pain and punishment from school authorities for failing to fulfil certain duties like assignments not done or absenteeism because of pain. Though a greater proportion of students without dysmenorrhea had pass scores than their counterparts, the difference was not statistically significant. Conclusion: Given these findings, school officials may benefit from considering dysmenorrhea in the context of improving their school attendance rates and academic performance of their students.

On Cultivating Students' Ability of Listening Comprehension in Senior High School in the Northwest of Guangxi

Nowadays, the role of listening course is changed and listening teaching begins to gain high priority in foreign language learning and teaching. However, the English level of students in China is still poor, especially in the northwest of Guangxi. One of the reasons is that teachers in senior high schools have a tendency to ignore listening, because they think that listening is time-consumed. They have to finish the teaching scheme punctually, though listening is the basic and important skill among the other three skills, listening teaching gains no large progress.

Relationship between Contraceptive Knowledge,Cognition and Behaviors among Vocational High School Students

Objective To study the relationship between contraceptive knowledge, cognition and behaviors among vocational high school students. Methods A cross-sectional survey was anonymously self-administrated by way of computer to all the 1st graders＇ among three vocational high schools in a district of Shanghai. Four cognition indicators, including perceived benefits, perceived barriers, perceived risks and self eJficacy were applied according to Health Belief Model. Results The percentage of respondents who reported ever sexual practices and contraceptives use at first sex was 7.01% and 56.64% respectively. Condom （58. 70%） and oral contraceptive pills （27.78%） were used by the majority. Main reasons for non-use were ＂shy to buy it＂ （26.53%） and ＂partner don＇t want to use any＂ （18.37%）. Proportion of respondents who ever had sex regarded withdrawal and rhythm as effective were 68.35% and 68.42% respectively. Proportion of respondents having sex knew ＂If a person was infected with STDs, he/she might not have noticeable symptoms＂ were 22.86%. Proportion of respondents who reported non-use of contraceptives at first sex considered that ＂infrequent intercourse could not cause a girl pregnant even she had experienced her menstruation＂ were 40.63%. Proportion of respondents who had ever used condom got full score of knowledge on ＂how to correctly use condom＂ were 23,26%. Perceived risks were poorest among four cognition indicators. High level of contraceptive knowledge was connected with high rate of contraceptives use at first sex, whereas high level contraceptive cognition was connected with high rate of contraceptive use both at first and recent sex. Conclusions It is important to provide youth-friendly services as well as message on contraceptives among vocational school students.

Reproductive Health Knowledge Level of High School and University Students in Shanghai

Objective To understand the sexual and reproductive health knowledge level of high school and university students in Shanghai. Methods A total of 628 high school students and 709 college students were surveyed with anonymous self-administrated questionnaire in Shanghai. Results The median knowledge scores of students from colleges and high schools were 58 and 39, respectively. Those who had surfed the Internet, had browsed websites on reproductive health, or had communicated sex-related issues with fathers/classmates/friends had more reproductive health knowledge. In addition, the percentage of college students who had surfed the Internet, had browsed websites on reproductive health or had communicated sex-related issues with classmates/friends was higher than that of high school students. Conclusion The knowledge scores of respondents were rather low. Compared with the high school students, the college students had more reproductive health knowledge and sought the knowledge more actively.

Sources of Sexual Knowledge among Vietnamese High School Students

This study determined the sources from which Vietnamese high school students currently acquire sexual knowledge as well as the sources from which they believe they should acquire it. Participants were eleventh-grade students at three public high schools in Hanoi, Vietnam. We conducted a questionnaire-based survey from September to October 2012, with 1672 students participating. Responses were received from all 1672 students, a response rate of 100%. Complete data were received from 1653 respondents (98.9%), including 896 males (54.2%) and 757 females (45.8%). The survey was a self-administrated questionnaire. Although many participants believed that they were knowledgeable about sex, only a small number of them actually possessed accurate sexual knowledge. Few participants in this study, targeted to a specific age (eleventh grade), had used the Internet as a major source for obtaining sexual knowledge, in contrast to results from previous studies which covered a wider age demographic. Future research should include comparative studies between eleventh and twelfth graders as well as between those of the same age who are and who are not enrolled in high school. Additionally, it might be beneficial to consider the relationship between adolescent age and Internet use to study the influence of the Internet on sexual knowledge. Our results suggest that parents and schoolteachers should shoulder more responsibility in providing sexual education, particularly by improving their own knowledge and ability to provide such education, because many participants indicated that sexual knowledge should be acquired from parents and schools.

The Correlation between Explicit Grammatical Knowledge,Implicit Grammatical Knowledge and Reading Comprehension Ability of Senior High School Students

The role of grammar in language teaching has always been the question that researchers debate.In recent years,grammar knowledge has been distinguished in the foreign language acquisition research,namely the implicit knowledge and the explicit knowledge(Dai Manchun 2005;Gu Qiyi 2005).As to the reaserch of implicit and explicit grammar knowledge as well as their measurement,it is easy to find that many scholars have studied the role of two different kinds of grammar knowledge in second language development.But the research on the role of implicit and explicit grammar knowledge in second language reading comprehension is too few,not to mention the research on the role of implicit and explicit grammar knowledge in English reading comprehension in the senior high school.The purpose of this study is to find the relationship between implicit and explicit grammatical knowledge and English reading comprehension ability of senior high school students.In addition,since the vocabulary is important to reading comprehension,this factor will also be considered in the study.

The Cross Sectional Study on the Association between Sexual Awareness and Cognitive Social Capital among High School Students in Ho Chi Minh City, Vietnam

Purpose: We aimed to reveal the association between cognitive social capital and sexual awareness among high school students in Ho Chi Minh City, Vietnam, where adolescent premarital sex is considered to be wide-spreading as consequence of socioeconomic changes, in comparison to our previous study in Hanoi, 2012. Methods: We conducted a questionnaire-based survey and a cross sectional study in late 2014, with 2051 eleventh graders at three high schools in Ho Chi Minh City. Complete data was received from 1935 respondents (94.3%). We assessed basic attributes, sexual knowledge, sexual awareness, sexual experience of peers, cognitive social capital such as a sense of community belonging, and Rosenberg Self-Esteem score. After the independent t-test and multiple logistic regression analyses on sexual awareness were performed assigning trivalent Rosenberg Self-Esteem score, sexual knowledge, and sexual experience of peers as independent variables (model 1), followed by analysis adjusted for cognitive social capital (model 2). This study was approved by Japanese Red Cross Akita College of Nursing (No. 24-003). Results: Of 1935 respondents, 99.9% were 16 or 17 years old and mostly from nuclear families (71.1%). Of all participants, 45.8% in males and 49.4% in females correctly answered on sexual knowledge, 47.6% of males and 28.3% of females accepted premarital sex, 60.0% of male and 65.0% of females knew peers with sexual intercourse experience, and 78.1% of males and 79.1% of females agreed with a sense of community belonging. When multiple logistic regression analyses performed, in model 1, sexual awareness was significantly associated with Rosenberg Self-Esteem score in female. In model 2, above association disappeared but significant association was found between sexual awareness and cognitive social capital in both sexes OR (95% CI), male 1.39 (1.05 - 1.84), female 1.99 (1.49 - 2.65). Discussion: The conservative traditional culture in both Hanoi and Ho Chi Minh City seems to be similar to the concept of cognitive social capital and it is considered to have influenced sexual awareness of high school students in Hanoi and Ho Chi Minh City, Vietnam. Conclusion: Cognitive social capital is significantly associated with sexual awareness among high school students in urban areas of Vietnam.

The mediating role of strengths use between character strengths and mental health in Chinese high school students

Motivations Underlying the Snack Choices of Japanese Junior High School Students: A Study Based on Cluster Analysis

The aims of the present study were to group junior high school students according to factors influencing their snack choice and identify differences between the characteristics and snack choice behaviors of the groups. An anonymous self-report questionnaire was administered to 1936 students (13 - 15 years old) in eight junior high schools in Tokyo, Japan. The students responded to the Snack Choice Questionnaire (SCQ) as well as questions concerning snacking behaviors, lifestyles, and demographics. Cluster analysis was applied to sort the sample according to SCQ scores. Each cluster’s characteristics were examined by gender using the χ2 test or the Kruskal-Wallis test with a Bonferroni adjustment. Participants were divided into four groups: high in all factors, low in all factors, low value in health, and value in health. The “value in health” group was composed of more girls than boys and the “low in all factors” group had fewer girls than boys. Those in the “high in all factors” and “low value in health” groups indicated that they consumed more snacks. Moreover, gender differences were revealed. By assessing the SCQ prior to providing nutrition education, we can obtain valuable information to make nutrition education planning.

Determinants of Sexual Awareness among High School Students in Tokyo, Japan―Post-Interventional Comparison Analysis in Relation to Social Capital

Purpose: This study was to clarify the association of sexual awareness of high school students with cognitive social capital (SC) in Tokyo, Japan. Method: In September 2017, we conducted a survey of 1073 third-grade high school students who were the same students who had participated in the same questionnaire survey at the prior academic year when they were second-grade students. A total of 1073 students were surveyed and 956 students responded. From six to eight weeks prior to this September 2017 survey, we implemented an educational intervention in the students. Then we compared the results of this survey with the previous survey of February 2017. We used logistic regression to assess sexual awareness and sex knowledge, sexually experienced surrounding peers and Self-Esteem score. The study was approved by the Ethical Review Board. Result/Discussion: Sexual awareness of high school students was significantly associated with SC both before and after the intervention. The higher SC one had, the higher sexual awareness was shown and the greater the sexual caution among both boys and girls was indicated. The study clarified the Determinants of Sexual Awareness of High School Students in Tokyo before and after the educational intervention. Conclusion: SC was found to be significantly associated with sexual awareness. SC should be emphasized in promoting adolescent reproductive health for the future.
