[Latent classes of health risk behaviors and their relationship with self-control among rural secondary school students in Guizhou Province].

OBJECTIVE: To understand the potential categories of health risk Guizhou Province. METHODS: From November to December 2021, 4452 rural students in middle school students with average age of(13.5±1.6) years were selected from Guizhou Province by multi-stage stratified random cluster sampling method.1505(33.8%) students in the first grade, 1958(44.0%) students in the second grade and 989(22.2%) students in the third grade. There were 2295 boys(51.5%) and 2157 girls(48.5%). Basic information questionnaire, health risk behavior questionnaire and self-control scale were used for questionnaire survey. Latent category analysis was used to explore the potential categories of health risk behaviors, and disordered multiple classification logistic regression analysis was used to explore the relationship between potential categories and self-control. RESULTS: The health risk behaviors of rural middle school students in Guizhou Province could be divided into four potential categories: low risk group(71.4%), medium risk group(11.6%), sub-high risk group(5.2%) and high risk group(10.7%). There were statistically significant differences in the distribution characteristics of potential categories of junior middle school students with different gender, grade, nationality, only child, accommodation, stay-behind, academic performance, academic pressure, peer relationship, parent-child relationship, teacher-student relationship and domestic violence(P<0.05 or P<0.01). Taking the low-risk group as the reference group, the highest self-control scores were in the medium risk group(OR=1.049, 95%CI 1.040-1.058), the sub-high risk group(OR=1.098, 95%CI 1.083-1.113), and the high risk group(OR=1.077, 95%CI 1.066-1.087). CONCLUSION: The latent characteristics of health risk behavior of rural junior middle school students in Guizhou Province are obvious. Improving self-control ability can reduce the occurrence of medium risk group, sub-high risk group and high risk group.

Effects of health education during public health emergencies on the health literacy, emotion and coping style of Chinese junior middle school students: a randomized controlled trial.

BACKGROUND: Schools are high incidence places for public health emergencies. Good health literacy helps students cope with public health emergencies. Overall, the health literacy of young students is relatively low. Health education can promote health literacy, but the health education related to public health emergencies for Chinese junior middle school students needs to be improved. To design and implement health education courses related to public health emergencies for junior middle school students and examine the impact on their health literacy, emotions, and coping styles. METHODS: From March to December 2022, 724 students in Grade 7 and Grade 8 of two junior middle schools in Changzhou were randomly divided into a course group (n = 359) and a control group (n = 365). The course group received an age-appropriate health education course that addressed public health emergencies; there were 12 classes, one per week. The control group received general health education. One week before and after the courses, the two groups of students were assessed with the Adolescent Health Literacy Evaluation Scale under Public Health Emergencies (AHLES-PHE), the Depression Self-Rating Scale for Children (DSRSC), the Generalized Anxiety Disorder 7-item scale (GAD-7), and the Simplified Coping Style Questionnaire (SCSQ). RESULTS: After the courses were completed, the scores of AHLES-PHE [156.0 (45.0,180.0) vs. 165.0 (54.0,180.0), P < 0. 05] in the course group increased significantly. The positive rate of DSRSC [81 (22.6%) vs. 57 (15.9%), P < 0.05] and GAD-7 [45 (12.5%) vs. 29 (8.1), P < 0.05]in the course group were significantly lower than those before courses. There was no significant difference in the above indices before and after courses in the control group (P > 0.05). CONCLUSION: This suggests that the health education courses related to public health emergencies designed in this study has an effect on improving health literacy, depression and anxiety in junior middle school students.

Reliability and validity of the Columbia suicide screen in junior middle school students / 中华行为医学与脑科学杂志

Objective To examine the reliability and validity of the Columbia suicide screen (CSS) in detecting suicide risk for junior middle school students.Methods Using convenient sampling,902 students of a junior middle school were tested with CSS and Beck depression inventory (BDI).Cronbach's alpha coefficient,parity split-half coefficient and test-retest reliability were examined after two weeks.Content validity was evaluated using specialist analysis and sensibility analysis.The BDI was used to explore the correlative validity.The convergent validity of CSS and another suicide risk screening method was examined.Results The proportion of students with suicide problem (suicide ideation or suicide attempts),suicide ideation within the previous year and suicide attempts in the past were 14.97％ (135/902),14.19％ (128/902)and 3.66％ (33/902) respectively.The Cronbach's alpha coefficient and Parity split-half coefficient of CSS were 0.844 and 0.908,respectively.The test-retest reliability of CSS were screening of suicide ideation (ICC =0.897),screening of suicide attempts (ICC =0.798),screening of substance use (ICC =0.882),screening of suicide problem (ICC =0.881),and screening of suicide problem combine depression (ICC =0.829)(P＜0.01).Sensibility analysis of CSS showed the cronbach α ranged from 0.834 to 0.845.Correlative validity between CSS and BDI were screening of suicide ideation (ρ =0.238,0.337,0.334,0.599),screening of suicide attempts (ρ =0.122,0.231,0.310,0.221),screening of depression (ρ =0.335,0.309,0.196,0.215),screening of suicide problem(ρ =0.240,0.328,0.321,0.590)and screening of suicide problem combine depression(ρ=0.212,0.324,0.320,0.474) (P＜0.01).Convergent validity between CSS and another suicide risk screening method were screening of suicide ideation (ρ =0.468),screening of suicide attempts (ρ =0.349),screening of suicide problem (ρ =0.453),and screening of suicide problem combine depression(ρ=0.469)(P＜0.01).Conclusion CSS has good internal consistency reliability,split-half reliability and content validity.Screening of suicide ideation,suicide attempts,suicide problem and suicide problem combine depression have good test-retest reliability,but the correlative validity and convergent validity are not satisfying.These four screening methods can only be used for preliminary screening suicide risk in junior middle school students.

On-campus bullying of 9th grade students and its impacts on health:An empirical analysis based on China education panel survey / 中国卫生政策研究

Objectives: To analyze the prevalence of bullying behavior among students of 9th grade across China in 2016 and to determine the impact of different types of bullying on students’physical and mental health. Methods:This paper adopted the China Education Panel Survey ( CEPS) conducted in 2016 using the sample design of PPS and cluster sampling. The survey population involved students of 9th grade and 8600 of them were respondents of the prepared questionnaire. Opting for the survey questionnaires to collect the basic information from the survey subjects, the study measured and compared the prevalence of physical, verbal, social and cyber bullying observed in 2016. Therefore, impacts of bullying on physical and mental/psychological health of students were respectively examined u-sing multiple OLS regression model and multi-factor sequential logit model. Results: The results of the survey found that during the past academic year, 49. 29% of students suffered verbal bullying, 37. 69% experienced social bull-ying followed by 18. 41% for those who caught physical bullying and finally 14. 08% were cyber bullied. The results of the multiple OLS regression analysis indicated that being bullied was a risk factor for students’ mental health, and social bullying was the most deleterious, followed by verbal bullying. The multi-factor sequential logit model results showed that the risk of illness was higher for students who were bullied than for those who were not bullied and verbal bullying was a notable health risk factor for physical health of students. Conclusions: Currently, verbal bullying is the most prevalent of the existing types of bullying in schools while new problems emerged with cyber bullying. Being bul-lied has a negative effect on both physical and mental health of students. The main risk factor for mental health is so-cial bullying and verbal bullying presents higher risks for physical health of students.
