Accessible Summary: What is already known?: SDM improves clinical outcomes by increasing attendance and treatment adherence in adolescents diagnosed with depression.SDM could reduce treatment disagreements and enhance consumers' and their families' satisfaction with mental healthcare services.Healthcare professionals are a critical part of SDM. However, MHPs' practices of SDM in the daily management of adolescents diagnosed with depression need to be clarified. What the paper adds to existing knowledge?: From the viewpoints of MHPs, SDM was not extensively applied in the daily management of adolescents diagnosed with depression.MHPs who trust their consumers and have received training related to SDM are more likely to practice SDM in the daily management of adolescents diagnosed with depression.The positive preferences for providing information and family involvement in treatment decision‐making are facilitators; working in closed inpatient mental health wards and open inpatient mental health wards are hindering factors for MHPs' practices of SDM. What are the implications for practice?: MHPs should encourage information sharing with consumers and their family members to help them participate in treatment decision‐making actively.A trusting and friendly therapeutic relationship with consumers should be maintained in the daily management of adolescents diagnosed with depression.SDM‐related training should be encouraged for MHPs to promote widespread SDM. Introduction: Shared decision‐making (SDM) is an ideal model for a therapeutic relationship that can improve health outcomes. Healthcare professionals are a critical part of SDM, and they play an important role in the practices of SDM in the clinical setting. Evidence suggests that adolescents diagnosed with depression can benefit substantially from SDM. However, mental health professionals' (MHPs) practices of SDM for adolescents diagnosed with depression in China are not well‐documented. Aim: This study aimed to investigate the practices of SDM for adolescents diagnosed with depression from the viewpoints of MHPs in China. Method: In this cross‐sectional study, we recruited a total of 581 MHPs by convenience sampling. The Shared Decision‐Making Questionnaire—Physician Version (SDM‐Q‐Doc) was used to evaluate the MHPs' practices of SDM for adolescents diagnosed with depression. Results: The mean SDM‐Q‐Doc was 80.47 (±16.31). Within the six specific decision‐making situations, most MHPs selected non‐SDM (52.7%–71.6%). Substantial numbers of respondents believed that MHPs made the final decision, especially with regard to the development (37%) and adjustment of medication regimens (42%). The practice of SDM was predicted by MHPs' preference for providing information, their trust in consumers, preference for family involvement in treatment decision‐making, working in an outpatient clinic and receiving SDM training (F = 23.582; p =.000; R2 =.198; adjusted R2 =.189). Discussion: Although the MHPs' self‐rated score of SDM‐Q‐Doc was high, SDM was not extensively applied in the daily management of adolescents diagnosed with depression. Thus, SDM needs to be further promoted by enhancing SDM‐related training for MHPs, thereby actively promoting the involvement of families, facilitating the information sharing for consumers and families, and building an active, trusting consumer‐practitioner relationship. Implications for Practice: MHPs should prioritise information sharing with consumers and families, as well as build trusting and friendly therapeutic relationships. Family involvement in treatment decisions should be encouraged when adolescents diagnosed with depression are in need. Actively participating in training related to SDM is also important. Future high‐quality evidence is still needed to explore the facilitators and barriers to SDM practices from a tripartite perspective of MHPs, adolescents diagnosed with depression and their families.

With the development of society, the number of autistic children in China is increasing, which not only makes the family's happiness very low, but also seriously affects the development of teenagers and society. Among the symptoms of autistic children, early childhood communication skills have received extensive attention. In traditional rehabilitation training, with a lack of parents' participation, most of the training cannot arouse the interest of autistic children, so the treatment effect is not obvious. Based on this, this paper proposes the application of family sports games to improve the early communication ability of autistic children. This article aims to investigate the role of family sports games in promoting the development of early communication skills in autistic children. This paper uses the fuzzy comprehensive evaluation method to score the comprehensive ability of family sports games. The experimental results of this paper show that before the experiment, the comprehensive scores of children's communication ability in the control group and the experimental group were 18.92 and 18, respectively, which were generally low, and there was no significant difference. This shows that the communication skills of the two groups of children before the experiment are relatively poor. After the test, the children's comprehensive score of communication ability in the experimental group increased by 35.8 points, and the difference was significant, indicating that family sports games have a great impact on the development of children's communication ability.

Previous studies have demonstrated that psychological needs frustration strongly influences adolescent depression. However, this influence's underlying mechanisms remain unknown, and related protective factors have not been identified. Based on an integration of basic psychological needs theory, the cognitive vulnerability model of depression, and findings regarding the link between psychological suzhi (a Chinese cultural construct that includes a hierarchical and integrated set of positive psychological qualities) and mental health, we assessed a structural equation model examining the mediating role of self-esteem and moderating role of psychological suzhi in the relationship between psychological needs frustration and depression. Participants were 1552 Chinese adolescents (Mage = 12.30, SD = 0.54, 49.10% male) who effectively completed paper-based questionnaires. The results indicated that psychological needs frustration significantly and positively predicted adolescent depression. Furthermore, the relationship between psychological needs frustration and depression was significantly mediated by self-esteem and significantly moderated by psychological suzhi; specifically, psychological suzhi buffered the association between psychological needs frustration and adolescents' depression. Additionally, we provide further evidence for the relationship between psychological needs frustration and depression, revealing the relevant underlying mechanisms and protective factors; these findings have practical relevance in the prevention and treatment of Chinese adolescents' depression. Highlights: Psychological needs frustration significantly and positively predicted adolescent depression. Self-esteem played a mediating role between psychological needs frustration and depression. Psychological suzhi played a moderating role in the association between psychological needs frustration and depression. [ABSTRACT FROM AUTHOR]

Purpose The purpose of this paper is to explore snacking behavior and perspectives on healthy and unhealthy food choices among adolescents in Mainland China.Design/methodology/approach Four focus-group interviews were conducted. Altogether 24 participants were recruited in Changsha, a second-tier city in China, through a convenience sampling process. They were asked to report their snacking behaviors, identify whether certain snacks are healthy or unhealthy and elaborate on factors affecting food choices.Findings Snacking was prevalent among the participants. The most frequently consumed snacks included fruit, milk and instant noodles. Participants’ evaluations for the healthiness of foods were based on the actual nutritional values of those foods, the effects on growth and body weight and word-of-mouth. Choice of snack was driven mainly by taste, image, convenience and health consciousness.Research limitations/implications The finding was based on a non-probability sample. The paper also did not explore the contexts where snacks were consumed.Practical implications Parents can make healthy snacks more accessible at home and at schools. Educators can teach adolescents how to read food labels. Schools can increase the availability of healthy snacks on campus. Social marketers can promote healthy snacks by associating them with fun and high taste.Originality/value This is the first paper on snacking behaviors among adolescents conducted in a second-tier city in China using focus-group methodology.

INTRODUCTION In recent years, e-cigarettes as an emerging tobacco product have been favored by college students. Our study aims to explore the factors affecting the use of e-cigarettes among college students and to put forward feasible suggestions for effectively controlling the use of e-cigarettes among college students. METHODS The participating students were from three undergraduate and three specialized colleges in Guangdong Province, surveyed from January to March 2022. The Fuzzy-set Qualitative Comparative Analysis (fsQCA) method was used to analyze the influence mechanism and path of five antecedents: self-efficacy, social environment, cognition, sales environment, and negative outcome expectation, on the use of e-cigarettes. The fsQCA used in this study is a novel research methodology that combines the strengths of qualitative and quantitative analyses, through which we can determine which conditions are essential to the outcomes that lead to e-cigarette use among college students, and which combinations of conditions are more important than others. RESULTS The interaction of self-efficacy, social environment, cognition, sales environment, and negative outcome expectation, affected college students' use of e-cigarettes. Through the fsQCA method, it was found that self-efficacy alone constitutes a necessary condition for college students not to use e-cigarettes. There are four possible pathways for college students not to use e-cigarettes, with higher self-efficacy, correct cognition, and a healthy social environment influencing the most important combination of conditions for college students to use e-cigarettes. CONCLUSIONS The use of e-cigarettes by students in Guangdong Province is the result of the synergistic effect of multiple factors. Tobacco control action suggestions focus on improving students' self-efficacy and paying attention to the combination of different factors to achieve more effective tobacco control.

Accessible Summary: What is known on the subject?: Prior research has demonstrated that childhood trauma can increase adolescents' suicidal ideation, and perceived stress plays a mediating role in the relationship between childhood trauma and adolescents' suicidal ideation. Character strengths, which are trait‐like positive personality characteristics, have also been found to be closely related to decreased stress and suicidal ideation. However, it is unclear whether character strengths act as a transfer mechanism that links childhood traumatic experiences with perceived stress and eventually suicidal ideation. What the paper adds to existing knowledge?: This study found that character strengths and perceived stress serially mediated the association between childhood trauma and suicidal ideation. Specifically, childhood trauma was associated with inferior character strengths, and the impaired character strengths further triggered high perceived stress, which was finally linked to a heightened risk of suicidal ideation. This study provided important theoretical implications for preventing suicidal risk among adolescents who are exposed to traumatic events during childhood. What are the implications for practice?: This study highlighted the roles of character strengths and perceived stress in the relationship between childhood traumatic experiences and suicidal ideation, which provided suggestions for designing nursing interventions to reduce adolescents' suicidal ideation, especially for those with traumatic childhood experiences. In addition to family nursing, school‐based regular monitoring and interventions of character strengths and perceived stress are necessary. Aim: This study sought to examine the mediating effects of character strengths and perceived stress on the relationship between childhood trauma and suicidal ideation among adolescents. Methods: A cross‐sectional survey was conducted on a sample of 1069 Chinese adolescents. The Chinese versions of the Suicidal Ideation Scale, Childhood Trauma Questionnaire, Perceived Stress Scale and Character Scale for Adolescents were used to assess adolescents' suicidal ideation, childhood trauma, perceived stress and character strengths. Results: The findings showed that childhood trauma influenced suicidal ideation directly and indirectly via perceived stress. Moreover, character strengths and perceived stress serially mediated the association between childhood trauma and suicidal ideation, implying that childhood trauma was associated with inferior character strengths, and the impaired character strengths further triggered high perceived stress, which was finally linked to a heightened risk of suicidal ideation. Conclusions: This study highlighted the joint contribution of childhood trauma, character strengths and perceived stress to suicidal ideation, providing theoretical and practical implications to guide mental health nurses to reduce the suicide risk among adolescents. Implications for Practice: These findings highlighted the importance of developing character strengths and stress‐coping strategies. Family nursing and school‐based regular monitoring and interventions of character strengths and perceived stress are necessary among adolescents who exposed to a high level of childhood trauma experiences to reduce their suicidal ideation and foster mental health.

Childhood obesity is related to impaired health and to some diseases in adulthood. Overweight children and adolescents have also been shown to experience social and psychological problems such as stigmatization and poor self-esteem. Thus, it is imperative to investigate the determinants of children and adolescents' weight outcomes. Through analyzing the 2004, 2006, 2009 and 2011 waves of survey data released by China Health and Nutrition Survey (CHNS), this paper studied how parental feeding knowledge and practices have impacted the weight status of Chinese children and adolescents aged 6 to 17. The paper focused on exploring how such impacts varied by parental gender and rural-urban residence. Logistic regression was used to conduct the analyses. The results showed that parental feeding knowledge and practices varied by gender and by rural-urban residence. Specifically, food preferences, energy intake (such as carbohydrate, protein and fat intake) and numbers of meals sharing with children showed different patterns among mothers and fathers. Maternal intervention on children and adolescents' eating and physical activities, parental energy intakes and meal sharing also showed rural and urban differences. The results further highlighted that the ways in which parental feeding knowledge and practices influenced children and adolescents' weight status also differed by parental gender and residence. Mothers were "gatekeepers" of children and adolescents' food choices and selection; their feeding practices played a more decisive role when influencing Chinese youth's weight status.

Cyber dating abuse victimization (CDAV) among female adolescents is common and harmful; however, little is known regarding how CDAV relates to victims' experiential avoidance in the Chinese context. Drawing from general strain theory, this cross-sectional study investigated possible differences in the relationships among CDAV, experiential avoidance, and self-compassion according to female adolescents' levels of interpersonal flexibility (low vs. high). A sample of 420 female adolescents aged 13 to 17 years (mean age = 15.78 years) who had been in intimate relationships during the past year participated in a voluntary and anonymous paper-and-pencil survey. Participants completed four self-reported measures on CDAV experience, self-compassion, experiential avoidance, and interpersonal flexibility. The findings indicated that nearly 49% of participants had experienced CDAV in the last year; CDAV exposure was directly linked with experiential avoidance and indirectly related to experiential avoidance through self-compassion. Moderation analyses showed that the negative associations between CDAV and experiential avoidance and self-compassion were only significant among participants with low interpersonal flexibility. These findings deepen the understanding of CDAV as a risk factor for reduced self-compassion and increased experiential avoidance in female adolescents. However, high interpersonal flexibility is a potential protector. This study has implications for the prevention of experiential avoidance among female adolescents exposed to CDAV and supports incorporating self-compassion and interpersonal flexibility skills to combat the negative outcomes of CDAV.

Adolescent suicide has become an increasingly serious social problem in China. Bullying victimization was found to be an influential factor of suicidal tendency, but less attention has been paid to the internal mechanisms of the relationship. This paper examined the relationship between adolescents' bullying victimization and suicidal tendency, and the mediating effects of internalizing problems and non-suicidal self-injury (NSSI). Generalized Structural Equation Model was employed to a sample of 3,575 Chinese secondary school students. Bullying victimization has a direct positive impact on adolescents' suicidal tendency, but also has an indirect impact on suicidal tendency through three paths: the independent mediating role of internalizing problems and NSSI, and the chain mediating role of internalizing problems and NSSI. The results suggested that students who are bullied tend to have a higher risk of suicidal tendency, and internalizing problems and NSSI are usually the prelude to suicidal behaviors.

BACKGROUND: The rapid development of science and technology and the swift improvement of people's material living standards enabled smartphones to be indispensable of people's daily lives. OBJECTIVE: The purpose of this paper was to examine the influence of self-control in adolescents' participation in physical activity on cell phone dependence. METHODS: The Physical Activity Rating Scale (PARS-3), the Self-Control Scale, and the Cell Phone Dependence Scale were used to measure the influence of self-control in adolescents' participation in physical activity on cell phone dependence among 649 adolescents. RESULTS: The results show: (1) There were significant differences (p < 0.01) in the physical activity levels of adolescents under different gender, birthplace, and education background. (2) Each dimensional variable of physical activity was negatively correlated with the cell phone dependence variable, and positively correlated with each variable of self-control, and the self-control variables were negatively correlated with cell phone dependence. (3) Self-control was partially mediating the effects of physical activity on cell phone dependence, with the mediating effect accounting for 39.68%. CONCLUSIONS: Adolescents' participation in physical exercise activities will improve self-control and ultimately reduce cell phone dependence. Curbing the negative and malignant events of cell phone addiction among adolescents, timely investigation of mobile phone and Internet addiction, pathological formation mechanisms and intervention measures are important measures to reshape the healthy lifestyle of adolescents and have great practical significance for the prosperity and development of families, society, nation and country.

The study aimed to describe and explore the behavioral dilemmas and support-requirement characteristics of self-management for epileptic adolescents during transition readiness.Methods: A convergent mixed-methods study was conducted. Patients (N=654) in eight hospitals in China completed a demographic and disease characteristics questionnaire and measures of epilepsy transition readiness, self-management of epilepsy, and perceived social support, and 17 patients and family care-givers were interviewed simultaneously.Results: Adolescents with epilepsy (AWEs) had low levels of self-management and transition readiness, and moderate levels of social support. Multivariate linear regression showed that age, antiepileptic drug type, comorbidities, family structure, transition readiness, and social support were statistically significant in the regression model (p< 0.05). Seven themes emerged in the qualitative analysis related to self-management behavioral dilemmas, and 11 themes emerged for support requirements. The findings from the qualitative and quantitative analyses were combined to create a conceptual model based on the SMART framework and the social cognitive theory.Conclusion: The findings indicate that the state of self-management behaviors of Chinese AWEs is not promising. The influential factors and characteristics are complex and systematic.Practice Implications: This study provides insights into the self-management practices of AWEs in China and expands previous self-management and transitional readiness strategies and models.

INTRODUCTION The World Health Organization recommends banning all forms of e-cigarette advertising, promotion, and sponsorship. The aims of the present study were to: 1) examine young people's exposure to e-cigarette advertising across a wide range of media in four diverse countries; and 2) identify any association between the number of different types of media exposures and e-cigarette use. METHODS A cross-sectional online survey was administered to approximately 1000 people aged 15-30 years in Australia, China, India, and the United Kingdom (n=4107). The survey assessed demographic characteristics, e-cigarette and tobacco use, numbers of friends and family members who vape, and exposure to multiple forms of e-cigarette advertising (e.g. television, radio, print, and various types of social media). Descriptive analyses were conducted on those who had heard of e-cigarettes (n=3095, significance threshold p<0.001) and a logistic regression analysis was used to identify factors associated with e-cigarette ever use (significance threshold p<0.05). RESULTS The majority (85%) of respondents who had heard of e-cigarettes reported being exposed to e-cigarette advertising on at least one type of media, and the average number of types of media to which respondents were exposed was 5 (range: 0-17). The number of media types was significantly associated with ever use of e-cigarettes (OR=1.05; 95% CI: 1.02-1.08, p=0.001). CONCLUSIONS Despite advertising restrictions in place in all four countries, large majorities of young people reported being exposed to e-cigarette advertising. Social media and advertising on/around vape shops and other retailers appear to be key exposure locations. Urgent attention is needed to address these forms of exposure given their apparent association with e-cigarette use. [ABSTRACT FROM AUTHOR]

INTRODUCTION This study was conducted to explore the characteristics and risk factors of e-cigarette use in adolescents, aiming for tobacco control and reducing e-cigarette use in this population. METHODS Using 1:1 matching, 88 students from three vocational high schools in Shanghai were recruited to conduct a case (using e-cigarettes) - control (not using e-cigarettes) study. Group interviews and questionnaire surveys were used for this qualitative and quantitative mixed-methods study. The keywords were extracted from the interview data and analyzed by the Colaizzi seven-step method. RESULTS The characteristics of adolescents' use of e-cigarettes include young age at first use, consumption of a large amount, as well as smoking in discrete locations in order to hide from adults. The reasons for using e-cigarettes include curiosity and wanting to replace traditional cigarettes. The risk factors of using e-cigarettes include insufficient understanding of the harm of e-cigarettes at the individual level (The positive outcome expectancy points: Z= -3.746, p<0.001; The negative outcome expectancy points: Z= -3.882, p<0.001), peer influence at the interpersonal level (χ²=6.510, p<0.01), and the influence of social and environmental factors such as e-cigarette sales in the stores and WeChat Moments (p<0.05 for all associations). CONCLUSIONS Having friends who use e-cigarettes, curiosity and sales exposure about e-cigarettes are important factors affecting the use of e-cigarettes by adolescents. It is necessary to strengthen the publicity of the potential hazards of e-cigarettes and to reduce overall usage by improving relevant laws and regulations. [ABSTRACT FROM AUTHOR]

Background High particulate matter with an aerodynamic diameter of 2.5 ≥m or less (PM2.5) exposure levels posed a great risk to human health, but the protection effects of environmental protection on cardiovascular disease have not been systematically evaluated. This study aims to illustrate the effect of the decreased concentration of PM2.5 on blood pressure level in adolescents after enacting the protection measures of environment from a cohort study. Methods A quasi-experimental study including 2415 children from the Chongqing Children's Health Cohort, aged 7.32±0.60 years with normal blood pressure at baseline, with 53.94% males, were analysed. Both the generalised linear regression model (GLM) and Poisson regression model were used to calculate the impact of the declining exposure level of PM2.5 on blood pressure and the incidence of prehypertension and hypertension. Results The annual mean PM2.5 concentration in 2014 and in 2019 were 65.01±6.46 µgmes per cubic metre (μg/m3), 42.08±2.04 μg/m3 respectively, and the decreased PM2.5 concentration between 2014 and 2019 was 22.92±4.51 μg/m3. The effect of decreased PM2.5 concentration by 1μg/m3 on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and the difference of blood pressure (BP) indexes between 2014 and 2019 were all significant (P<0.001). The absolute differences of SBP (-3.598 mmHg; 95% confidence interval (CI)=-4.47,-2.72 mmHg), DBP (-2.052 mmHg; 95% CI=-2.80,-1.31 mmHg) and MAP (-2.568 mmHg; 95% CI=-3.27,-1.87 mmHg) in the group with a decreased level of ≥25.56 μg/m3 were more significant than those in a decreased concentration of PM2.5 for <25.56 μg/m3 (P<0.001). And the incidence of prehypertension and hypertension for three occasions blood pressure diagnose was 2.21% (95% CI = 1.37%-3.05%, P=0.001) in children with PM2.5 decreased level -25.56 μg/m3 (50%), which was significant higher than its' counterparts 0.89% (95% CI=0.37%-1.42%, P=0.001). Conclusions Our study found the etiological relationship between the declining PM2.5 concentration and the BP values and the incidence of prehypertension and hypertension in children and adolescents, suggesting continuous environmental protection measures in China have achieved remarkable health benefits.

Background Comparing body fat and the effect of body fat on metabolic abnormalities in Chinese and USA teenagers may provide clues for the early prevention and control of cardiovascular disease (CVD). We aimed to compare the prevalence of glucose and lipid metabolism abnormalities, body fat amount and distribution, and the effect of body fat on glucose and lipid metabolism in Chinese and US teenagers. Methods We included 5424 Chinese teenagers (48.5% male) from the China Child and Adolescent Cardiovascular Health (CCACH) study and 8704 USA teenagers (55.6% male) from the USA National Health and Nutrition Examination Survey (NHANES). Blood lipid, blood glucose, and body fat indicators were obtained using the same standardised measurements. Results The prevalence of dyslipidaemia in Chinese teenagers was of those in the USA (hypercholesterolaemia = 3.5% vs 7.4%; high low-density lipoprotein cholesterol (LDL-C) = 3.6% vs 5.0%; low high-density lipoprotein cholesterol (HDL-C)=9.9% vs 14.3%; hypertriglyceridaemia=3.7% vs 10.1%) (P<0.05). However, with the increase in body mass index (BMI), the prevalence of high LDL-C increased more in Chinese than in US teenagers, even exceeding them in the obese group (2.7% in non-overweight to 9.7% in overweight group in China, P<0.05; 3.5% in non-overweight to 6.5% in the obese group in the USA, P<0.05). The prevalence of impaired fasting glucose was higher in China than in the USA (28.0% vs 17.5%, P<0.05). Besides, Chinese adolescents are more likely to accumulate fat in the abdomen, and the per-unit fat increase would bring a higher risk of dyslipidaemia in Chinese boys than in USA boys. Conclusions Dyslipidaemia was more prevalent in US teenagers than in Chinese teenagers, but with the increase in BMI, the prevalence of high LDL-C increased more in Chinese than in US teenagers. Impaired fasting glucose (IFG) was significantly more prevalent in China than in the USA. The unfavoured body fat and higher risk of body fat on metabolic disorders in Chinese teenagers suggest that Chinese teenagers should pay more attention to the adverse effect of body fat on metabolic abnormalities.

Background: Since December 2021, Wuxi, China has offered a two-dose human papillomavirus (HPV) vaccination to 14-year-old females for free. This study evaluated the costs and benefits of this vaccination scheduled in the Expanded Program on Immunization in Wuxi from the perspective of the cities' demographic characteristics, economic development, and policy support. Methods: The model-based economic evaluation used TreeAge Pro software to construct a decision tree-Markov model for the vaccination strategy in which 100,000 14-year-old females received two doses of bivalent HPV vaccine or no vaccination. Costs and effects of the strategy were assessed from a societal perspective through literature research and data obtained from the Wuxi Centre for Disease Control and Prevention. Univariate, multivariate, and probabilistic sensitivity analyses assessed the stability of the findings. Results: The cost of the bivalent HPV vaccine in Wuxi is 711.3 CNY. The two-dose of bivalent HPV vaccine for 100,000 14-year-old females would cost an additional 658,016 CNY compared to no vaccination, but would result in 1,960 Quality Adjustment Years of Life (QALYs). Using the per capita gross domestic product of 187,415 CNY in 2021 in Wuxi as the willingness-to-pay threshold, the vaccination strategy costs 3,357.37 CNY per QALY gained, which is much lower than the threshold, suggesting that it is a very cost-effective strategy. In addition, the vaccine strategy reduced the incidence of cervical cancer by 300 cases and cervical cancer deaths by 181 cases, representing a benefit-cost ratio of 2.86 (> 1) when health output outcomes were measured in monetary terms. These results suggested that the vaccination strategy was advantageous. Sensitivity analyses showed that changes in the parameters did not affect the conclusions and that the findings were robust. Conclusions: Compared to no vaccination, the delivery of two doses of bivalent HPV vaccine for 14-year-old females was a more highly cost-effective and optimal strategy. [ABSTRACT FROM AUTHOR]

Introduction: At present, the incidence of adolescent depression is increasing each year, having a wide and profound impact on adolescents. This study investigated the mood state of mid-to-late adolescents and young adults and analyzed related factors; clarified the incidence of depression, suicide, and self-injurious thoughts/behaviors in this population; and conducted relevant analysis of related factors of depression and anxiety. Methods: Study subjects were students aged 14-25 years, from three high schools and one university in Liaoning Province. Study subjects were evaluated using several questionnaires that combined online and offline methods. Specifically, the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Simplified Coping Style Questionnaire (SCSQ), Child Depression Inventory (CDI), the Chinese version of the Spence Child Anxiety Scale (SCAS), and a general questionnaire were utilized. Single-factor ANOVA, t-test, Chi-square, and multiple regression analysis were used to analyze the data. Results: The results showed that, among the 14-17-year-old subjects, the incidence of depression was 336 (14.7%), the incidence of anxiety was 763 (33.5%). Among the 18-25-year-old subjects, the incidence of depression was 34 (8.6%), the incidence of anxiety was 7 (1.8%). In the general questionnaire, 2081 (77.8%) individuals were depressed, 689 (25.8%) had thoughts of self-injury, and 323 (12.1%) had self-injurious behaviors. Among the 14-17-year-old subjects, 1789 (78.46%) were depressed, 689 (30.22%) had self-injury thoughts, and 319 (1.71%) had self-injurious behaviors. Among the 18-25-year-old subjects, 292 (73.92%) were depressed, but 4 (1.01%) had self-injurious behaviors. The incidence of depression and anxiety in adolescents is high, presenting with a certain risk of self-injury. However, age is an important factor in the occurrence of depression and anxiety; among the 18-25-year-old subjects, the incidence of depression (8.6% vs. 4.7%) and anxiety (1.8% vs. 33.5%) was lower than that among the 14-17-year-old population. Through comparative analysis, adolescents aged 14-17 remained at high risk of depression and anxiety. Discussion: In the analysis of risk factors for depression and anxiety, relationships with classmates, teachers, and parents were reported as important influencing factors of emotional state. Further, a good coping style was found to be protective against depression and anxiety. [ABSTRACT FROM AUTHOR]

This paper reports the development and baseline data of a vignettes-based measure of gender equality. Methods: Vignettes were developed through 3-day long focus groups. After piloting in 13 sites and repiloting a revised version in 6 countries, responses were categorized by the construct tapped and a scoring system developed. Finalized vignettes were then tested in DR Congo, Ecuador and China. Results: Young adolescents can successfully respond to vignettes; and can differentiate self from hypothetical protagonists of same and opposite sex. Response differences by sex of respondent and protagonist were statistically significant across a range of scenarios and settings. Conclusion: This is the first vignettes-based measure for young adolescents assessing young adolescent perceptions of relationships differentiated by sex of the protagonist. [ABSTRACT FROM AUTHOR]

The Flourishing Scale (FS) is a brief eight-item inventory used to measure psychological well-being. This study evaluated the psychometric properties of the FS in a sample of 766 Chinese adolescents. The paper-and-pencil method was adopted. Confirmatory factor analysis was conducted to examine the factor structure of the FS items. Expanded Satisfaction With Life Scale and Hospital Anxiety and Depression Scale were used to examine the criterion-related and incremental validities. Results showed good internal consistency reliability, one-factor structure, strong convergent validity, and incremental validity of the FS in the current sample. We can conclude that the FS is suitable for use in the Chinese adolescent context. [ABSTRACT FROM AUTHOR]

INTRODUCTION Adolescent smoking is a serious public health concern, and the role of personnel in reducing students'tobacco use has been proven. Anti-tobacco policies are strong factors for tobacco control but most are newly implemented in China. This study aimed to examine the awareness of anti-tobacco policies among school personnel in a southern city of China, and assess its influence on personnel's anti-tobacco attitudes and behaviors towards students. METHODS An online cross-sectional study was conducted between September 2017 and January 2018 in schools of Shanghai, China. A total of 3194 subjects from 33 schools were selected by a two-stage stratified cluster randomized sampling design. Prevalence of anti-tobacco policy awareness is presented. Crude (ORs) and adjusted odds ratios (AORs) and their 95% confidence intervals (CIs) were estimated to assess the association between policy awareness and anti-tobacco attitudes or behaviors. RESULTS In all, 22.4% of surveyed participants knew four or five polices presented in the survey and 13.0% of personnel knew none of these policies. Most of the participants fully support prohibiting indoor (94.6%) and outdoor (86.3%) smoking in public places, bans on tobacco advertising (90.9%), and printing warning pictures on cigarette boxes (89.5%). Less than half of the personnel had taken action to stop students from smoking (45.7%), encourage students to quit smoking (42.4%) or participated in relevant educational activities held by schools (37.4%) in the previous year. The school personnel's anti-tobacco attitudes (AOR=1.28; 95% CI: 1.21-1.36) and behaviors (A0R=1.10; 95% CI: 1.03-1.17) were strengthened with increasing level of policy awareness. CONCLUSIONS The involvement of school personnel can be an important part of intervention to improve anti-tobacco campaigns on campus. The study calls for the implementation of projects or activities to improve anti-tobacco policy awareness in the school environment as part of school tobacco control strategy. [ABSTRACT FROM AUTHOR]

Limited research has been conducted on dispositional mindfulness, posttraumatic stress disorder (PTSD) symptoms and academic burnout in Chinese adolescents following a tornado. The present study investigated the ways in which dispositional mindfulness is related to PTSD symptoms and academic burnout in Chinese adolescents following a tornado by considering the role of regulatory emotional self-efficacy. A total of 431 Chinese adolescents (mean age: 14.75 years) who had experienced a severe tornado 9 months prior to this study were recruited for this study. The results indicated that our model fit the data well [χ2/df = 2.774, CFI = 0.952, TLI = 0.934, RMSEA (90% CI) = 0.064 (0.051-0.077)], and revealed that regulatory emotional self-efficacy partially mediates the relationships between dispositional mindfulness and PTSD symptoms and academic burnout, respectively. The clinical implications and limitations of our research, and recommendations for future research, are discussed in this paper. [ABSTRACT FROM AUTHOR]

Objective: To understand the prevalence of home-related anxiety among adolescent athletes during the novel coronavirus pandemic and to ascertain the factors influencing this anxiety. Methods: We employed cluster sampling to select 1150 adolescent athletes (aged 8–18 years) from six sports training schools in Yantai City, Shandong Province. Mental health status was assessed and recorded. Chi-square tests and multivariable logistic regression were used to analyze the factors contributing to athletes' anxiety. Results: The survey revealed a COVID-19 infection rate of 38.23% (437 individuals) with an anxiety score of 40.98 ± 8.20 and an anxiety detection rate of 11.29% (129 individuals) during the COVID-19 epidemic. Female athletes exhibited a higher anxiety rate of 14.40% compared to 8.40% in male athletes. Multivariate analysis identified female gender as a risk factor for anxiety (OR = 1.64), while participation in aquatics emerged as a protective factor (OR = 0.24, 95% CI: 1.08–2.48). Professional training duration exceeding three years increased anxiety risk (OR = 3.05, 95% CI: 1.67–5.58), as did not seeking help during difficulties (OR = 2.59, 95% CI: 1.33–5.01). Interestingly, parental care was linked to increased anxiety risk (OR = 2.44, 95% CI 1.34–4.44), while care from friends was protective (OR = 0.60, 95% CI: 0.36–1.01), which was possibly due to the pressure associated with parental expectations. Conclusions: Adolescent athletes, particularly females and those with extended training durations, exhibit a heightened susceptibility to anxiety. This study also highlights that athletes who proactively seek assistance during challenging situations tend to experience lower anxiety levels. Additionally, a lack of COVID-19 infection and the involvement of concerned parents contribute to reduced anxiety among these young athletes. [ABSTRACT FROM AUTHOR]

There is a growing but limited literature on psychological distress among Chinese students, especially the impact of the COVID-19 pandemic, using a longitudinal comparison between in school and at home. This study aimed to assess the psychological status of adolescents in school and related risk and protective factors. We surveyed 13,637 adolescents before the COVID-19 outbreak (T1) and 10,216 after two months of home confinement (T2). The 9-item Patient Health Questionnaire (PHQ-9) was used to assess depressive symptoms or the severity of depression among the adolescents. In addition, the Childhood Trauma Questionnaire and the Connor-Davidson Resilience Scales were also used to screen for experiences of abuse and neglect and to measure resilience in adolescents. At baseline, 22.34% reported depressive symptoms. At T2, this rate decreased to 14.86%. When adolescents were in school, age (P <.0001), gender (P <.0001), and experience of abuse (P <.0001) were risk factors, while parent–child relationship (P <.0001), and resilience (P <.0001) were protective factors for depressive symptoms. After leaving school, age and physical abuse were no longer risk factors for depression. The negative impact of school education on the mental health of adolescents in China exceeds even the impact of the pandemic and home isolation. The focus should be on those adolescents with abuse experience and poor parent–child relationships to prevent the onset of psychological and psychiatric disorders. [ABSTRACT FROM AUTHOR]

Background: Nowadays, moderate gaming behaviors can be a pleasant and relaxing experiences among adolescents. However, excessive gaming behavior may lead to gaming disorder (GD) that disruption of normal daily life. Understanding the possible risk factors of this emerging problem would help to suggest effective at preventing and intervening. This study aimed to investigate the prevalence of GD and analyze its possible risk factors that adolescents with GD. Methods: Data were collected between October 2020 and January 2021. In total, a sample of 7901 students (4080 (52%) boys, 3742 (48%) girls; aged 12–18 years) completed questionnaires regarding the Gaming-Related Behaviors Survey, Gaming Disorder Symptom Questionnaire-21 (GDSQ-21); Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS Scale); Emotion Regulation Questionnaire (ERQ); Short-form Egna Minnenav Barndoms Uppfostran for Chinese (s-EMBU-C); and Adolescent Self-Rating Life Events Checklist (ASLEC). Results: The prevalence of GD was 2.27% in this adolescent sample. The GD gamers were a little bit older (i.e., a higher proportion of senior grades), more boys, with more gaming hours per week in the last 12 months, with more reward responsiveness, maternal rejecting and occurrence of negative life events (e.g., interpersonal relationships, being punished and bereavement factors). Conclusion: These possible risk factors may influence the onset of GD. Future research in clinical, public health, education and other fields should focus on these aspects for provide target prevention and early intervention strategies. [ABSTRACT FROM AUTHOR]

Background: The effects of antipsychotic (AP) medications on cognitive functions in individuals at clinical high-risk (CHR) of psychosis are poorly understood. This study compared the effects of AP treatment on cognitive improvement in CHR adolescents and adults. Methods: A total of 327 CHR participants, with an age range of 13 to 45 years, who underwent baseline neuropsychological assessments and a 1-year clinical follow-up were included. Participants with CHR were categorized into four groups based on their age: adolescents (aged < 18) and adults (aged ≥ 18), as well as their antipsychotic medication status (AP+ or AP−). Therefore, the four groups were defined as Adolescent-AP−, Adolescent-AP+, Adult-AP−, and Adult-AP+. Results: During the follow-up, 231 CHR patients received AP treatment, 94 converted to psychosis, and 161 completed the 1-year follow-up. The Adolescent-AP+ group had more positive symptoms, lower general functions, and cognitive impairments than the Adolescent-AP− group at baseline, but no significant differences were observed among adults. The Adolescent-AP+ group showed a significant increase in the risk of conversion to psychosis (p < 0.001) compared to the Adolescent-AP− group. The Adult-AP+ group showed a decreasing trend in the risk of conversion (p = 0.088) compared to the Adult-AP− group. The Adolescent-AP− group had greater improvement in general functions (p < 0.001), neuropsychological assessment battery mazes (p = 0.025), and brief visuospatial memory test-revised (p = 0.020), as well as a greater decrease in positive symptoms (p < 0.001) at follow-up compared to the Adolescent-AP+ group. No significant differences were observed among adults. Conclusions: Early use of AP was not associated with a positive effect on cognitive function in CHR adolescents. Instead, the absence of AP treatment was associated with better cognitive recovery, suggesting that AP exposure might not be the preferred choice for cognitive recovery in CHR adolescents, but may be more reasonable for use in adults.

The potential impact on mental health of home schooling and social isolation due to COVID-19 lockdowns has led to widespread concern, particularly for adolescents. However, studies including pre-pandemic data from longitudinal cohorts with an assessment of the longer-term impact of the Covid-19 pandemic beyond the first months of 2020 are scarce. This longitudinal study of 1534 adolescents attending a secondary school in Hunan province investigated self-reported symptoms of anxiety and depression using two validated scales (Screen for Child Anxiety Related Disorders, Child Mood and Feelings Questionnaire) at six time points before, during, and after the 2020 national lockdown restrictions in China. Perceived COVID-related stress was assessed by an author-developed scale at two timepoints during the lockdown. We investigated trends in symptoms over time with a fixed effects model and multiple imputations of missing data. Counter to our expectations, depressive and anxiety symptoms were reduced during the 2020 lockdown relative to pre-lockdown (depression: b = − 3.37, SE = 0.345, Cohen's d = − 0.25, p < 0.0001; anxiety: b = − 4.55, SE = 0.382, Cohen's d = − 0.30, p < 0.0001). Symptoms remained significantly reduced even after lockdown restrictions eased. Higher symptom levels during lockdown were associated with greater self-reported COVID-related stress (depression: b = 0.11, SE = 0.026, p < 0.0001; anxiety: b = 0.11, SE = 0.036, p < 0.0001). Although COVID-related stresses correlated with higher levels of anxiety and depression, the lockdown period was associated with improved symptom levels in the adolescents taking part in our study. School closures may have improved the mental health of adolescents in China. We speculate this beneficial effect of lockdown can be explained by the adverse effects of attending school itself such as exposure to bullying and achievement pressures. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate the relationship between family socioeconomic status (SES) and adolescents' learning conformity and self-esteem among a sample of 15–18 year-old high school students. Methods: A survey was conducted on 339 adolescents using measures of family SES, self-esteem, and learning conformity. An intermediary effect model was constructed to examine the mediating mechanism of self-esteem in the impact of family SES on adolescents' learning conformity. Results: In our study, we observed that male adolescents were more likely to come from families with higher socioeconomic status (SES) and exhibited relatively higher levels of self-esteem compared to female adolescents. However, this finding should be regarded as an observational outcome specific to our study sample and does not directly indicate a causal relationship between gender and family SES or self-esteem. Adolescents from rural areas were more likely to exhibit tendencies towards learning abidance and compliance. Family SES positively predicted self-esteem. The intermediary model indicated that family SES significantly positively influenced learning abidance and compliance, with self-esteem partially mediating the effects at 33.49% and 33.33%, respectively. Family SES negatively affected learning obedience, with self-esteem partially mediating the effect at 39.77%. Conclusion: Among the 15–18 year-old high school student population, family SES not only directly affects learning abidance, compliance, and obedience but also generates an indirect mediating effect through self-esteem.

Introduction: With the rapid rise of the Internet, it has become an indispensable part of adolescents’ learning and lives. To promote sustainable development of the Internet, fostering good Internet moral literacy among adolescents is particularly important. Given the current absence of a Chinese version of the Internet Moral Literacy Scale suitable for adolescents, this study translated and conducted two studies on the scale developed by Lau and Yuen. Methods: In Study 1, item analysis and factor validity analysis of the scale were conducted with 343 adolescents from China. In Study 2, a large‑scale cross‑sectional survey was conducted to analyze descriptive statistics, factor validity, measurement invariance across genders, difference analysis, and concurrent validity of the scale. The study 2 involved 7837 Chinese adolescents. Results: The results from study 1 showed that most items met the specified criteria. However, one item exhibited higher internal consistency than the overall Cronbach’s alpha value when removed. Exploratory factor analysis indicated a more suitable two‑dimensional model, with one item showing cross‑loading issues. Study 2 revealed that the Internet Moral Literacy Scale had good internal reliability, and the two‑factor structure exhibited excellent factor validity. In addition, significant gender differences in Internet moral literacy levels were identified, with males scoring lower than females. A significant negative correlation was found between Internet moral literacy and both cyberbullying (r = −0.87, P < 0.001) and moral disengagement (r = −0.75, P < 0.001). Conclusion: Chinese version of the Internet Moral Literacy Scale has good psychometric properties. [ABSTRACT FROM AUTHOR]

Although cyber victimization has been suggested as a significant risk factor for the development of adolescents' depression, the underlying psychopathological process that mediates this relationship needs further exploration. Based on the psychological inflexibility model, this study aimed to examine cognitive fusion and experiential avoidance as serial mediators in the relation between cyber victimization and depression. A total of 556 Chinese adolescents completed a set of online self-report questionnaires measuring cyber victimization, cognitive fusion, experiential avoidance, and depression. A bias-corrected bootstrap approach was used to test the serial mediation model. The results showed that cyber victimization predicted adolescents' depression not only directly but also indirectly through three paths: the mediating role of (1) cognitive fusion and (2) experiential avoidance, and (3) the serial mediating role of cognitive fusion and experiential avoidance. These findings provide insight into the interventions for depression in adolescent cyber victims. [ABSTRACT FROM AUTHOR]

China is a country experiencing urgent and rapid urbanisation as it integrates Western ways of knowing and being. These rapid changes pose particular challenges for adolescents negotiating constructs of identity between worldviews. This paper will present a report on observations made on a recent scoping visit by two nurse academics to three Chinese cities. An ecological framework will be used to discuss and critique emerging health issues for adolescents. These were identified as 'early love', 'internet use and abuse', 'physical violence' and 'stealing'. Community health nurses are challenged to make sense of these issues and how best to support adolescents, their families and communities. Contexts of care for community health nurses are also problematic as adolescent education takes priority as a driver for economic growth. Accordingly, this paper will also explore enablers and barriers for this group of community health nurses. [ABSTRACT FROM AUTHOR]

This paper presents findings from a Department of Health-funded study into the emotional well-being of young people seeking asylum on their own in the UK. It discusses how young people accounted for only partly disclosing information about the circumstances surrounding their quest for asylum and subsequent aspects of their lives since arriving in the UK. Foucault's panoptic mechanism and its focus on the effects of power as dispersed through scrutiny are applied as a theoretical framework to contextualise these experiences. The paper shows that young people's decisions about how much of their current or past lives they share with others are more complex than indicated by earlier research. The paper argues that, for many young people, the predominant impetus for selective disclosure was a desire to retain a degree of agency as they navigated their way through immigration, asylum, social care, health and education systems and simultaneously sought to establish themselves in the social world. These findings have implications for how social care (and other) professionals engage and work with young people seeking asylum alone. [ABSTRACT FROM PUBLISHER]

INTRODUCTION Secondhand smoke (SHS) exposure affects tobacco related health behaviors during adolescence and persists into adulthood. This study aimed to investigate the influence of SHS exposure on tobacco use among adolescents stratified by school and gender, and provide recommendations for controlling tobacco use in youth. METHODS Through stratified random cluster sampling, 12278 selected students (aged 13-18 years) from schools in China were administered questionnaires. Multiple logistic regression was used to analyze whether SHS exposure would increase the smoking risk and susceptibility of adolescents. RESULTS The prevalence of SHS exposure among the participating students was 74.8%. Adolescents exposed to SHS were at higher odds of being susceptible and currently smoking. Students with SHS exposure at both home and public places accounted for 36.6%, greatly increasing the current smoking risk and smoking susceptibility. Home SHS exposure had greater impact on the current tobacco use of boys (OR=2.13; 95% CI: 1.50-3.03) and junior school students (OR=4.67; 95% CI: 2.41-9.06). Exposure from public places increased the risk of current smoking in boys (OR=4.20; 95% CI: 2.31-7.65) and smoking susceptibility of vocational school students (OR=1.51; 95% CI: 1.07-2.15). Students with high-level exposure to SHS had 2.25 times higher odds of e-cigarette use. CONCLUSIONS The prevalence of SHS exposure is still high among adolescents in China and is associated with increased risk for tobacco use regardless of gender and school level. Effective smoke-free strategies should be developed and strictly implemented. Boys and junior school students constitute vulnerable populations exposed to SHS at home. [ABSTRACT FROM AUTHOR]

Background: Waist-to-height ratio (WHtR) is considered an important summary indicator for assessing the health of children and adolescents. However, there are fewer studies addressing the association between WHtR and cardiorespiratory fitness (CRF). Deriving an optimal WHtR would play an important role in promoting CRF in children and adolescents. Our aim was to analyze the association between WHtR and CRF and determine the optimal value of WHtR. Methods: In this study, 37,081 (19,125 boys, 51.6%) children and adolescents aged 7–18 years in five regions of China were tested for WHtR and 20-m shuttle run test (20 m SRT). One-way ANOVA was used to compare maximum oxygen uptake (VO2max) among children and adolescents with different WHtRs and effect sizes were used to analyze differences between groups. Curvilinear regression was used to analyse the curvilinear relationship that exists between WHtR and VO2max. Results: In Chinese children and adolescents, the WHtR of boys was higher than that of girls by 0.01, and the difference was statistically significant (P < 0.001). Overall, in the age groups of 7–9, 10–12, 13–15, and 16–18 years old, the differences in VO2max comparisons between different WHtR groups were statistically significant (P < 0.001). In Chinese children and adolescents in the age groups of 7–9, 10–12, 13–15, and 16–18 years old, VO2max levels were highest when the WHtR was 0.34, 0.32, 0.39, and 0.41, respectively. Conclusions: There is a curvilinear association between WHtR and CRF in Chinese children and adolescents. Both lower and higher WHtR led to a decrease in VO2max in children and adolescents.

The present study aimed to examine the bidirectional relationship between indigenous psychological capital (i.e., task-oriented psychological capital and guanxi-oriented psychological capital) and adolescent problematic Internet use (PIU) in the context of Chinese culture. The participants were 980 adolescents (Mage = 14.99, SD = 1.69) recruited from two middle schools in southern China. They provided self-report data on indigenous psychological capital and PIU as well as demographic variables at the beginning and the end of a school year. After controlling for gender and stressful life events, the results showed that (1) Task-oriented psychological capital and guanxi-oriented psychological capital at the beginning of the school year respectively predicted adolescent PIU at the end of the school year. (2) PIU at the beginning of the school year negatively predicted individuals' task-oriented and guanxi-oriented psychological capital at the end of the school year. (3) There were no gender differences in bidirectional relationship between indigenous psychological capital and Chinese adolescents' PIU. These findings help us understand the causes and results of PIU among Chinese adolescents and inspire related interventions for PIU and psychological capital. [ABSTRACT FROM AUTHOR]

The Annual Report on Cardiovascular Health and Diseases in China (2022) intricate landscape of cardiovascular health in China. This is the first section of the report, which dissects influential factors across diverse domains. The investigation identifies tobacco use as a paramount concern, portraying China as the global epicenter of tobacco consumption. Cigarette smoking, exacerbated by second-hand smoke exposure, emerges as a critical and preventable risk factor, contributing to a surge in attributable deaths over the past three decades. In the realm of dietary nutrition, the study discerns an overall improvement, yet discerns worrisome deviations, notably an escalating fat intake surpassing recommended guidelines. The shifting dietary structure reveals diminished consumption of cereals and vegetables juxtaposed with an uptick in animal foods, while excessive intake of cooking oil and salt persists, straying substantially from endorsed levels. The exploration of physical activity patterns unfolds a nuanced narrative. Varied trends are observed among students, with concerns arising from sedentary behaviors and inadequate adherence to recommended guidelines. The analysis spans a trajectory of declining physical activity in Chinese adults, coupled with an alarming surge in sedentary leisure time, ultimately linking these factors to heightened risks of cardiovascular diseases and increased adiposity. An examination of overweight and obesity trends uncovers a relentless upward trajectory, projecting substantial prevalence by 2030. Noteworthy prevalence rates underscore the imperative for targeted interventions to curtail this burgeoning health crisis, with the anticipated prevalence extending to nearly two-thirds of the adult population. Psychological factors, notably depression, constitute an integral facet of cardiovascular health. Prevalence rates among patients with coronary artery disease and acute myocardial infarction underscore the intricate interplay between mental health and cardiovascular outcomes. Additionally, persistent depressive symptoms are shown to significantly elevate the risk of cardiovascular diseases and mortality. This first section underscores the multifaceted challenges facing cardiovascular health in China, emphasizing the imperative for tailored interventions across tobacco control, dietary habits, physical activity, obesity management, and psychological well-being to mitigate the escalating burden of cardiovascular diseases in the population.

Background: Parenting is a common and potent environmental factor influencing adolescent anxiety. Yet, the underlying neurobiological susceptibility signatures remain elusive. Here, we used a longitudinal twin neuroimaging study to investigate the brain network integration and its heritable relation to underpin the neural differential susceptibility of adolescent anxiety to parenting environments. Methods: 216 twins from the Beijing Twin Study completed the parenting and anxiety assessments and fMRI scanning. We first identified the brain network integration involved in the influences of parenting at age 12 on anxiety symptoms at age 15. We then estimated to what extent heritable sensitive factors are responsible for the susceptibility of brain network integration. Results: Consistent with the differential susceptibility theory, the results showed that hypo-connectivity within the central executive network amplified the impact of maternal hostility on anxiety symptoms. A high anti-correlation between the anterior salience and default mode networks played a similar modulatory role in the susceptibility of adolescent anxiety to paternal hostility. Genetic influences (21.18%) were observed for the connectivity pattern in the central executive network. Conclusions: Brain network integration served as a promising neurobiological signature of the differential susceptibility to adolescent anxiety. Our findings deepen the understanding of the neural sensitivity in the developing brain and can inform early identification and personalized interventions for adolescents at risk of anxiety disorders.

Background: Self-harm, a severe mental health concern among children and adolescents, has varying global prevalence rates. Previous studies have suggested potential associations between specific behavioral aspects of biological rhythm and self-harm risk in these populations. Objective: Our study aimed to elucidate the relationship between biological rhythm patterns and the propensity of self-harm among Chinese children and adolescents using the Baoxing Youth Mental Health (BYMH) cohort. Methods: We included 1883 Chinese children and adolescents from the BYMH cohort. The self-report questions used to assess biological rhythm and self-harm. We applied Principal Component Analysis (PCA) to distinguish patterns of biological rhythms. Logistic regression models were conducted to estimate the associations between biological rhythm, as well as biological rhythm patterns and risk of self-harm. Results: Of the participants, 35.0% reported experiencing lifetime self-harm. PCA revealed six significantly predominant biological rhythm patterns. Elevated risks of self-harm were linked with unhealthy eating practices, daytime tiredness, and unhealthy bedtime snacking. Conversely, patterns emphasizing physical exercise, family meals for breakfast, and nutritious diet exhibited decreased self-harm propensities. These trends persisted across varied self-harm attributes, including type, recency, and frequency of self-harm. Conclusions: This study underscores the critical impact of biological rhythms on self-harm risks among Chinese youth. Targeted lifestyle interventions, focusing on improved sleep and dietary habits, could serve as potent preventive measures. Our findings lay the groundwork for future longitudinal studies to further probe these associations, fostering the creation of tailored interventions to curb self-harm and enhance mental well-being in younger populations.

Background: Childhood maltreatment are well-established risk factors for adolescent psychopathology. Positive childhood experiences (PCEs) known protective factors. However, few studies have simultaneously investigated childhood maltreatment and PCEs in the context of longitudinal study. The aim of this paper was to assess the buffering effect of PCEs in adolescence in the association between chronic childhood maltreatment and psychological symptoms in adolescence.Methods: Data were from an ongoing longitudinal study with 2288 children aged 8.15 y at baseline who were recruited from 3 large elementary schools in China. Participants were followed up for four waves across 6 years. The associations between re-victimization and poly-victimization with adolescent psychopathological symptoms across different PCEs contexts were explored.Results: Poly-victimization was highly predictive of depressive symptoms, oppositional defiant disorder and conduct disorder. PCEs may mitigate the negative effect of chronic childhood maltreatment on adolescent psychopathology in a dose-response manner. For adolescents with 4-5 PCEs, psychopathological symptoms score decreased significantly and showed similar level with those low/no-victimization comparison peers. While experiencing multiple PCEs does decrease the risk of psychopathological symptoms, certain PCEs, such as parental warmth and peer support, appear to entailed protective effect on all the three psychopathological symptoms.Limitations: It is not clear whether the patterns of effects would vary across developmental periods.Conclusions: A focus of interventions should be not only on ameliorating childhood maltreatment, but also on expanding the availability of social support related PCEs, which may help inform suitable strategies for providing intervention and support to best help reduce the psychopathology burden for children.

This paper investigated the impact of eye-closed and weighted training (EWMT) on the stroke effect of adolescent table tennis players. Forty-eight adolescent table tennis players were randomly selected from the China Table Tennis College and were divided into two groups as 1) the experimental group (EG, n = 24) in which they engaged in multi-ball exercise with eye-closed and weighted swing for 10 weeks, and 2) the control group (CG, n = 24) in which they received a normal training without eye-closed and weighted swing intervention. The stroke effect was assessed by three outcome measures: accuracy, stability, and ball speed. Results showed that 1) both the traditional training method and EWMT can improve the stroke effect of adolescent table tennis players. 2) In terms of accuracy, the number of stroke in the corner area was significantly different between EG and CG after the experiment (p = 0.022, p < 0.001, respectively). 3) In terms of stroke stability, there was a significant difference in the number of net ball strokes between EG and CG after the experiment (p = 0.014). 4) In terms of ball speed, there was no significant difference between EG and CG after the experiment (p = 0.871). 5) After EWMT, the stroke stability of backspin had more significant improvement than that of topspin. Thus, compared with the traditional training method, the EWMT method can improve the stroke effect of adolescent table tennis players in terms of accuracy and stability more significantly; the EWMT method can improve the stroke effect of backspin more significantly than that of topspin in terms of stability.

Taking advantage of China's send‐down movement as a natural experiment, we investigate how experiencing a political movement during adolescence affects political participation decades later. Using data from the China Family Panel Survey and the regression discontinuity design, we find that the send‐down experience significantly reduces individuals' political participation, measured by their participation in community committee elections, time spent on community service activities and how much they care about public news. Further analysis suggests that the send‐down experience negatively affects political participation through poorer mental health and less trust in local government. [ABSTRACT FROM AUTHOR]

INTRODUCTION Exposure to tobacco-related information is an important factor in youth smoking initiation. This study aims to explore the relationship between exposure to pro-smoking and anti-smoking media and adolescents' current smoking status and susceptibility to smoking, as well as the interaction between exposure to pro-smoking and anti-smoking media information. METHODS This cross-sectional study was conducted in 2017. We recruited 12278 students from junior, senior and vocational high schools located in Shanghai, China. The exposure of participants to tobacco promotional and control messages over the past 30 days was examined, as well as current smoking and susceptibility to never smokers' initiation. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using complex samples procedure logistic regression, adjusting for related covariables. RESULTS There were 89.3% and 91.5% of adolescents exposed to tobacco pro- smoking and anti-smoking messages. Exposure was more prevalent among males, suburb school and vocational school students. Exposure to pro-tobacco and anti- tobacco messages, separately, increased and decreased the risk of current smoking and susceptibility to never-smokers' smoking, respectively, especially among males and junior high school students. Risk was associated with the exposure level (p-trend<0.001). Tobacco control messaging was found to mitigate the influences of tobacco promotion on the risk of both current smoking (AOR=0.64; 95% CI: 0.41--0.99) and susceptibility to smoking (AOR=0.65; 95% CI: 0.46--0.93). CONCLUSIONS Exposure to tobacco-related messages was highly prevalent and associated with youth smoking and susceptibility to smoking. It is therefore important to enhance the comprehensiveness and enforcement of promotion bans. Given that tobacco control information can counter the impact of tobacco promotion information on smoking risk, the publicity and dissemination of tobacco control information should be consistently strengthened.

As a severe public health concern directly endangering life safety, adolescent suicide has been extensively investigated in variable-centered studies. However, gaps remain in the knowledge of heterogeneous suicide risk patterns and their developmental nature. Additionally, little is known about protective factors associated with suicide risk patterns and changes. This study applied person-centered approaches to explore suicide risk profiles and transitions over time in early Chinese adolescents, along with their protective factors. A total of 1518 junior high school students (49.6% girls, Mage = 13.57, SD = 0.75) participated in two surveys within a 12-month interval. Latent Profile Analysis and Latent Transition Analysis were used to model the profiles and transitions of suicide risk. Three risk profiles were identified at both time points: low risk profile (73.9, 78.3%), medium risk-high threat profile (16.2, 10.2%), and high risk profile (9.9, 10.2%). Low risk profile was stable, while medium risk-high threat and high risk profiles showed great transitions over 12 months. Sense of control, meaning in life, and regulatory emotional self-efficacy served as protective factors against suicide risk profiles and transitions. Findings underscore the importance of comprehensively illustrating suicide risk states from multiple aspects, as well as understanding the fluid nature of transitions between different risk states. Prevention and intervention strategies aimed at enhancing resilience, such as increasing sense of control, perceived meaningfulness, and belief in emotional regulation, may contribute to reducing the risk of suicide among adolescents.

Adolescent future orientation is highly relevant to the sociocultural context in which they are situated. However, adolescents in non-Western cultures are underrepresented in literature. This study investigated the profiles and developmental transitions of adolescent educational future orientation, as well as the roles of adolescent academic achievement and perceived parental educational expectations within the context of Chinese culture. The sample was 605 (54.5% boys) urban and rural senior high school students followed for one and a half years. Three distinctive profiles were identified: the concentrated-committed profile characterized by the concentrated goals (i.e., hopes and fears for future education) and the highest level of planning and evaluation components, the low profile scoring the lowest on each component, and the tentative profile characterized by the highest level of hopes and fears density and mean levels of planning and evaluation components. Latent transition analysis revealed high stabilities for the concentrated-committed and the low profiles but very low stabilities for the tentative profile, and transitions were more common in ways from low or tentative profiles to the concentrated-committed profile rather than vice versa. Greater academic achievement predicted the concentrated-committed profile. Perceived parental educational expectations increased adolescent educational future orientation, particularly for urban adolescents or those in the tentative profile. Urban adolescents were more likely to be in or transition into the concentrated-committed profile, particularly for those with higher academic achievement or parental expectations. These findings demonstrate the heterogeneities of adolescent thinking about future education, reveal how the Chinese sociocultural factors contribute to shaping the development of adolescent future orientation, and provide implications for the promotion of adolescent future orientation in education.

This paper examines the dimensionality and factorial invariance of the Chinese Positive Youth Development Scale (CPYDS) using multigroup confirmatory factor analyses (MCFA). Secondary 1 students ( N = 5,649) responded to the CPYDS in the context of a positive youth development program. Results showed that there are 15 basic dimensions of the CPYDS which are subsumed under four higher-order factors (i.e., cognitive-behavioral competencies, prosocial attributes, positive identity and general positive youth development qualities). Evidence of factorial invariance in terms of configuration, first-order factor loadings, second-order factor loadings, intercepts of measured variable, and intercepts of first-order latent factor, was found. The findings suggest that the CPYDS has stable dimensions that can be used to assess positive youth development in Chinese adolescents. [ABSTRACT FROM AUTHOR]
