Assessing the Mental Health of Brazilian Students Involved in Risky Behaviors

Associations between parental autonomy support and depressive symptoms among Chinese college students: the chain-mediating effects of mindfulness and self-esteem

Introduction

Despite extensive research on contextual factors will relieve college students' depressive symptoms, significant gaps remain in understanding the underlying mechanisms of this relationship, particularly through individual strength factors such as mindfulness and self-esteem. Based on self-determination theory, we explore the association between parental autonomy support and depressive symptoms among Chinese college students and whether mindfulness and self-esteem serve as mediators.

Methods

A total of 1,182 Chinese college students aged 16 to 27 years (Mage = 20.33, SD = 1.63; female = 55.7%) participated in this research. Questionnaires pertaining to parental autonomy support, mindfulness, self-esteem, and depressive symptoms were administered.

Results

The results revealed that depressive symptoms were negatively correlated with both paternal and maternal autonomy support, with mindfulness and self-esteem acting as chain-mediators. Specifically, mindfulness and self-esteem were positively impacted by parental autonomy support, whereas depressive symptoms were negatively impacted by mindfulness and self-esteem. Furthermore, paternal and maternal autonomy support significantly impacted depressive symptoms via both direct and indirect pathways. Indirect effects included three paths: mediation through mindfulness, mediation through self-esteem, and mediation through the mindfulness and self-esteem chain.

Discussion

The study highlights the fundamental mechanisms that account for the association between Chinese college students' parental autonomy support and depressive symptoms, these insights can be used to prevent and manage mental health problems among Chinese college students. For example, parents' autonomy support can directly reduce depressive symptoms, but we can also indirectly promote college students' mental health by emphasizing the mediation role of students' mindfulness and self-esteem.

Association Between Social Support, and Depressive Symptoms Among Firefighters: The Mediating Role of Negative Coping

Background

Depressive symptoms (DS) can erode physical and mental health; social support (SS) is considered a buffer for DS and a promoter for improving coping and recovery abilities. However, there is almost no research on the mediating role of negative coping (NC) in SS and DS, especially among firefighters.

Methods

A cross-sectional survey was conducted among firefighters in Chongqing, China, and the valid data of 407 firefighters were collected through questionnaires distributed on the WeChat platform in 2020. Statistical Product and Service Solutions (SPSS) 26.0 is used for descriptive statistics and correlation analysis. Structural equation modeling was adopted to analyze the association among SS, NC, and DS. The mediation effect is also evaluated.

Results

Firefighters' detection rate of DS is 23.3%, and when they receive more SS were less likely to develop DS. NC was positively correlated with DS (β = 0.54, p < 0.001) after controlling for SS. Besides, the results of structural equation modeling showed that NC partially mediates the relationship between SS and DS (standard error = 0.039, indirect effects = 0.109, 95% confidence interval: 0.047-0.200 p < 0.001).

Conclusion

NC has a partial indirect effect between SS and DS among firefighters. SS could not only affect DS directly but also indirect work on it by affecting NC. This discovery will be a novel and meaningful part of the research on the firefighter population.

Indicators of Eating Disorders in Sexually Abused Brazilian Adolescents: Family and School Contexts

Eating disorders, characterized by abnormal eating behaviors, are among a wide variety of psychiatric conditions that mainly affect children and adolescents. These disorders have a multifactorial origin and can be associated with restrictive diets, negative feelings, harmful family relationships, and post-traumatic stress. Thus, this study's objective was to evaluate the association between indicators of eating disorders and family and school contexts in Brazilian adolescents who previously experienced sexual abuse and examine the findings based on sex. National School Health Survey data were utilized. Among 102,301 students between 11 and 19 years of age, 4124 reported having experienced sexual abuse and were included in this study. Self-report questionnaires were used to assess participants' health status and the presence of risk behaviors, which were examined through multivariate analysis using a Poisson regression model. The results indicated positive relationships between self-induced vomiting, laxative misuse, and other purgative methods and infrequent meals with family, hunger, and the presence of violence in students' daily lives, regardless of sex (p < 0.05). In addition, body dissatisfaction and negative feelings about one's body were associated with having been bullied or teased by schoolmates for both sexes (p < 0.05). Distant relationships with parents were associated with purgative methods and body dissatisfaction among female students (p < 0.05). In conclusion, body dissatisfaction, negative feelings about one's body, laxative misuse, self-induced vomiting, and purgative methods were found to be associated with factors in family and school contexts such as hunger, infrequent meals with family, family violence, distant relationships with parents, and bullying at school in adolescents who have previously experienced sexual abuse.

From Social Rejection to Welfare Oblivion: Health and Mental Health in Juvenile Justice in Brazil, Colombia and Spain

(1) Background: This study aims to examine and describe the policies of three Latin American countries: Colombia, Brazil, and Spain, and identify how they implement their support systems for health, mental health, mental health for children and adolescents, and juvenile justice systems that support judicial measures with treatment and/or therapeutic approaches specialized in mental health. (2) Methods: Google Scholar, Medline, and Scopus databases were searched to identify and synthesize of the literature. (3) Results: Three shared categories were extracted to construct the defining features of public policies on mental health care in juvenile justice: (i.) models of health and mental health care, (ii.) community-based child and adolescent mental health care, and (iii.) mental health care and treatment in juvenile justice. (4) Conclusions: Juvenile justice in these three countries lacks a specialized system to deal with this problem, nor have procedures been designed to specifically address these situations within the framework of children's rights.

Relationship between depression and quality of life among students: a systematic review and meta-analysis

The objectives of this systematic review were to estimate the prevalence of depression and to identify the relationship between depression and quality of life (QOL) among high school and university students. Literature search was performed in the Scopus, Embase, PubMed, Scielo, CINAHL and Web of Science databases, following the PRISMA methodology. The results were presented through descriptive approaches and meta-analysis. Thirty-six studies met the eligibility criteria, and twenty-six were included in the meta-analysis. The prevalence of depressive symptoms was 27% (95% CI 0.21-0.33) among students, being high school and university students was 25% (95% CI 0.14-0.37) and 27% (95% CI 0.20-0.34), respectively, and most studies have shown that depression was associated with low QOL. Among the limitations of the study is the difficulty of generalizing the results found, considering the large sample of health students. New studies should be conducted considering the severity, duration, and patterns of depressive symptoms in high school and university students, to better understand the relationship between depression and QOL.

Related factors to the coping style of patients with sudden sensorineural hearing loss

BACKGROUND

Coping style can affect the patient's physical and mental health management. Therefore this study aimed to identify factors related to the coping style of young and middle-aged sudden sensorineural hearing loss (SSNHL) patients to provide reference for clinical nursing practice.

METHODS

A cross-sectional study was conducted on young and middle-aged SSNHL patients hospitalized in the otolaryngology departments of four hospitals in Suzhou City, China. A paper-based self-administered questionnaire investigated the patient's coping style and related factors. Multiple linear stepwise regression analysed the effective related factors in patients' coping styles.

RESULTS

Among 872 patients, 866 completed the survey, with an average age of 37.27 y. Factors related to the coping style of these patients included gender, chronic diseases, history of trauma, social support and type D personality (p<0.05). Female patients adopt more negative coping styles than male patients. Patients with chronic diseases or a history of trauma had more positive coping styles. Higher social support scores were related to improvements in coping style. Patients with type D personality were more likely to adopt negative coping styles.

CONCLUSIONS

This study suggests that psychological assessment of patients, chronic diseases, history of trauma, social support and type D personality may benefit the understanding of these patients' coping styles and, as a consequence, may improve their stress management.

Attention-deficit/hyperactivity disorder as a risk factor for cardiovascular diseases: a nationwide population-based cohort study

Accumulating evidence suggests a higher risk for cardiovascular diseases among individuals with mental disorders, but very little is known about the risk for overall and specific groups of cardiovascular diseases in people with attention-deficit/hyperactivity disorder (ADHD). To fill this knowledge gap, we investigated the prospective associations between ADHD and a wide range of cardiovascular diseases in adults. In a nationwide population-based cohort study, we identified 5,389,519 adults born between 1941 and 1983, without pre-existing cardiovascular diseases, from Swedish registers. The study period was from January 1, 2001 to December 31, 2013. Incident cardiovascular disease events were identified according to ICD codes. Hazard ratios (HR) with 95% confidence intervals (CI) were calculated using Cox proportional hazards regression model, with ADHD as a time-varying exposure. After an average 11.80 years of follow-up, 38.05% of individuals with ADHD versus 23.57% of those without ADHD had at least one diagnosis of cardiovascular disease (p<0.0001). ADHD was significantly associated with increased risk of any cardiovascular disease (HR=2.05, 95% CI: 1.98-2.13) after adjusting for sex and year of birth. Further adjustments for education level, birth country, type 2 diabetes mellitus, obesity, dyslipidemia, sleep problems and heavy smoking attenuated the association, which however remained significant (HR=1.84, 95% CI: 1.77-1.91). Further adjustment for psychiatric comorbidities attenuated but could not fully explain the association (HR=1.65, 95% CI: 1.59-1.71). The strongest associations were found for cardiac arrest (HR=2.28, 95% CI: 1.81-2.87), hemorrhagic stroke (HR=2.16, 95% CI: 1.68-2.77), and peripheral vascular disease/arteriosclerosis (HR=2.05, 95% CI: 1.76-2.38). Stronger associations were observed in males and younger adults, while comparable associations were found among individuals with or without psychotropic medications and family history of cardiovascular diseases. These data suggest that ADHD is an independent risk factor for a wide range of cardiovascular diseases. They highlight the importance of carefully monitoring cardiovascular health and developing age-appropriate and individualized strategies to reduce the cardiovascular risk in individuals with ADHD.

Interventions in Chinese Undergraduate Students' Mental Health: Systematic Review

BACKGROUND

Over 30% of university students from 8 countries were afflicted with mental distress according to a World Health Organization survey. Undergraduate students in increasing numbers in China have also been reported to suffer from different mental problems. Various psychological distresses significantly impact their academic and daily life, thereby causing role impairments and unsatisfactory academic achievements. While the prevalence of, diverse underlying factors for, and interventions of social support in college students' mental health have extensively been investigated in China, there is no study exclusively focusing on the impact of interventions on their psychological well-being.

OBJECTIVE

The aim of this review was to identify and synthesize the interventions in the mental health concerns of Chinese undergraduate students studying in China reported in the literature to inform educational authorities, college and university management, students' affairs counselors, and mental health providers.

METHODS

We performed a systematic review and reported the research findings of previous studies according to the protocol of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 statement. First, based on the predefined search strategy, keyword searches were performed in the PubMed and ProQuest databases to retrieve relevant studies. Subsequently, we screened the candidate articles based on predefined inclusion and exclusion criteria. Finally, we analyzed the included papers for qualitative synthesis.

RESULTS

We retrieved a total of 675 studies from the PubMed and ProQuest databases using the search strategy on March 15, 2022. Among these candidate studies, 15 that were not written in English, 76 duplicates, and 149 studies of other document types were removed before screening. An additional 313 studies were excluded in the screening process, with 73 articles ruled out for being not relevant to interventions, not related to mental health, or not focused on undergraduate students in the full-text review. As a result, 49 papers were eligible and included in this systematic review. In the qualitative synthesis, we divided the interventions reported in the selected studies into two categories: (1) social support from government authorities, university authorities, students' affairs counselors and teachers, family members, health care authorities and professionals, and the media (various online platforms), and (2) various coping strategies adopted by undergraduate students themselves. We identified further research on mental health interventions that may be delivered by digital medical platforms, conversational agents (eg, chatbots), and researchers.

CONCLUSIONS

This was the first systematic review of interventions to address the mental health concerns of Chinese undergraduate students studying in China. The categorization of reported interventions and the identification of new intervention channels can effectively inform stakeholders. Interventions for undergraduate students' mental health is a research topic worth further investigation.

Depressive Symptoms and Their Associated Factors in Vocational-Technical School Students during the COVID-19 Pandemic

The objectives of this study were to compare the prevalence of depressive symptoms, behavioral habits, and QoL in students from two vocational–technical schools, and to determine the association of depressive symptoms with behavioral habits and quality of life (QoL) in these students during the COVID-19 pandemic. A cross-sectional survey was conducted with students attending the institution of the Brazilian Federal Network of Professional, Scientific and Technological Education. The students answered a questionnaire on sociodemographic variables, situations related to the COVID-19 pandemic, behavioral habits, QoL, and depressive symptoms. The outcome variable was the presence of depressive symptoms, assessed using the Children’s Depression Inventory (CDI). Poisson regression analysis with robust variance was performed. A total of 343 students participated in this study (women, 55.7%; mean age of 16.1 ± 0.93 years). The prevalence of depressive symptoms among students was 43.4% (95% confidence interval [CI]: 38.0–49.0), and these symptoms were significantly associated with being female (prevalence ratio [PR] 1.72; 95% CI: 1.31–2.27); being in the 10th grade (PR: 1.80; 95% CI: 1.18–2.76) and 9th grade (PR 2.08; 95% CI: 1.37–3.18); social isolation (PR: 2.04; 95% CI: 1.00–4.14); hunger due to a lack of food at home (PR: 1.78; 95% CI: 1.33–2.39); low physical activity levels (PR: 1.68; 95% CI: 1.09–2.59); and moderate (PR: 2.87, 95% CI: 1.68–4.89) and low QoL (PR: 5.66; 95% CI: 3.48–9.19). The results emphasize the importance of interventions aimed mainly at female students and those in the initial years of high school, in addition to the importance of physical activity, food safety, and QoL to improve the mental health of students.

Impacts of Stress and Risk Perception on Mental Health of College Students During the COVID-19 Pandemic: The Mediating Role of Coping Efficacy

OBJECT

In this study, we aimed to explore the influences of pandemic stress, risk perception, and coping efficacy on the mental health of Chinese college students during the COVID-19 pandemic.

METHODS

A nationally representative sample of Chinese college students (N = 3,381, M age = 20.85, SD age = 1.31) took part in an online survey during the COVID-19 pandemic. Correlation coefficients, structural equation modeling, and other statistical analysis methods were used for data analysis.

RESULTS

(1) The Chinese college students' pandemic stress and perceived pandemic risk were found to be moderate (3.51 ± 0.83, 3.45 ± 0.94), whereas their perceived infection risk was lower (2.10 ± 0.67). Their mental health during the COVID-19 pandemic was found to be good (3.80 ± 0.73). (2) The quality of their mental health was significantly and negatively associated with pandemic stress, perceived pandemic risk, and perceived infection risk. The level of their mental health was significantly and positively associated with coping efficacy, and their coping efficacy was significantly and negatively associated with pandemic stress, perceived pandemic risk, and perceived infection risk.

CONCLUSION

Coping efficacy played a partial mediating role in the relationship between pandemic stress and mental health, coping efficacy played a partial mediating role in the relationship between perceived infection risk and mental health, and coping efficacy played a complete mediating role in the relationship between perceived pandemic risk and mental health. Our findings show the importance of fostering college students' coping efficacy to improve their mental health during the COVID-19 pandemic.

Prevalence of sexual abuse and its association with health-risk behaviors among Brazilian adolescents: A populational study

BACKGROUND

Analysis of sexual abuse has usually been neglected in research at developing countries despite its everlasting consequences. This study examined the prevalence of sexual abuse among Brazilian adolescents according to data from the National School Health Survey (PeNSE) and analyzed it based on Brazilian regions, sociodemographic aspects, health information, and health-risk behaviors among Brazilian adolescents who reported having experienced sexual abuse previously.

PARTICIPANTS AND SETTING

The PeNSE data were utilized, and the sample included 102,072 students from all over Brazil, aged between 11 and 19 years.

METHODS

Data were collected by questionnaires and were analyzed by multivariate analysis using the Poisson regression model.

RESULTS

The results denoted a relation between sexual abuse, social determinants of health variables (i.e., black, indigenous, and mixed skin color/ethnicity; Brazilian region public school, age between 15 and 18 years, and low education level of the mother), and health-risk behaviors (i.e., early sexual intercourse, having multiple sexual partners, unprotected sexual intercourse, use of tobacco, alcohol, and illicit drugs).

CONCLUSION

Therefore, reports of sexual abuse are associated with risky behaviors. Given these findings, targeted interventions on sexual abuse are essential for the health of adolescents and the prevention of risky behaviors, and can also facilitate programs to prevent sexual abuse.

The impacts of coping style and perceived social support on the mental health of undergraduate students during the early phases of the COVID-19 pandemic in China: a multicenter survey

BACKGROUND

An increasing number of undergraduate students in China have been reported to have psychological problems. In response to the COVID-19 pandemic, a series of preventive and control measures were implemented, which undoubtedly worsened their psychological health. Coping style and social support were probably important factors that affected the psychological well-being of undergraduate students during the pandemic. This study aimed to explore the effects of coping style and perceived social support on the psychological well-being of college students and relevant risk factors.

METHODS

This cross-sectional study was performed in February and March of 2020 by distributing an online questionnaire among undergraduate students from seven geographical regions across China. The questionnaire included sociodemographic information; the 21-item Depression, Anxiety and Stress Scale (DASS-21); the Perceived Social Support Scale (PSSS); and the Simplified Coping Style Questionnaire (SCSQ). For the analyses, t-tests, one-way analysis of variance (ANOVA), the Kruskal-Wallis test and multiple linear regression were utilized. The level of significance was set at P < 0.05.

RESULTS

Among 3113 college students, the rates of anxiety, depression and stress symptoms were 13.3, 15.4 and 6.8%, respectively. Increased rates of current smoking and drinking (5.5 and 25.2%, respectively) among undergraduates were identified. The results indicated that the PSSS subscales and SCSQ subscales were significantly associated with DASS-21 scores (P < 0.001). Multiple linear regression analysis showed that active coping style and family support were protective factors while passive coping style could aggravate psychological problems among participants (P < 0.001).

CONCLUSIONS

A remarkable number of college students adopted passive coping strategies to cope with negative feelings, such as smoking and drinking, which were detrimental to their mental health. In contrast, active coping strategies helped improve their psychological well-being. Moreover, family support was particularly important for maintaining their mental health and ameliorating mental health challenges in this major health crisis. Consequently, suitable psychointervention, routine screening for risk behaviors, and provision of further social support are needed for undergraduate students in the COVID-19 pandemic or other emergency public health events.

The Impact of the COVID-19 Pandemic on Students' Mental Health and Sleep in Saudi Arabia

Background: Mental health problems are prevalent among university students in Saudi Arabia. This study aimed to investigate the impact of the COVID-19 pandemic on university students’ mental health and sleep in Saudi Arabia. Method: A total of 582 undergraduate students from Saudi Arabia aged between 18 and 45 years old (M = 20.91, SD = 3.17) completed a cross-sectional online questionnaire measuring depression, anxiety, stress, resilience, and insomnia during the COVID-19 pandemic (2020). Analysis included an independent samples t-test, one-way ANOVA, and Hierarchical regression analysis. Results: Undergraduate students reported high levels of depression, anxiety, and perceived stress and low levels of resilience (p < 0.001) during the pandemic. In addition, students reported experiencing insomnia. A hierarchical regression analysis indicated that lower resilience, high levels of insomnia, having a pre-existing mental health condition, and learning difficulties (such as dyslexia, dyspraxia, or dyscalculia) were significantly associated with high levels of depression and stress. In addition, lower resilience, a high level of insomnia, and pre-existing mental health conditions were significantly associated with high levels of anxiety. Finally, a lower level of psychological resilience and a high level of insomnia were significantly associated with increased levels of depression, anxiety and stress within university students. Conclusion: This study has provided evidence that a lower level of psychological resilience and insomnia were associated with mental health problems among undergraduate students in Saudi Arabia, thus enhancing psychological resilience and interventions to support sleep and mental health are vital to support student well-being outcomes throughout the pandemic.

Child and Adolescent Mental Health and Resilience-Focussed Interventions: A Conceptual Analysis to Inform Future Research

Internationally, the mental health of children and adolescents is undoubtedly an important construct of theoretical, clinical, and policy level concern. Worldwide, five mental disorders (depression, alcohol misuse, bipolar affective disorder, schizophrenia, and obsessive-compulsive disorder) represent half of the 10 leading causes of disability and premature death; with mental disorders accounting for 15–30% of disability adjusted life years in the first three decades of life. This provides a solid rational founded in implications for population health as to why reducing and preventing mental health problems in children and adolescents deserves attention. Past research has indicated interventions focussed on building resilience through strengthening protective factors may offer the potential to address mental health problems in children and adolescents, and in particular aid in reducing such problems during times of increased risk or adversity. With childhood and adolescence being critical periods of development, there is a need to reflect on the strengths and limitations of resilience-focussed interventions and anticipated future needs of the world’s youth. This conceptual analysis identifies a number of future research directions that may meaningfully add to the evidence base and improve implementation, evaluation, and impact of resilience-focussed interventions. These largely relate to refining the understanding of how resilience protective factors relate to mental health problems in children and adolescents. Important issues and potential opportunities to improve the related research field include improved reporting of intervention content; improved measurement of resilience protective factors in intervention trials; continued reporting and review of evidence of association between protective factors and mental health outcomes; and incorporation of mediation analysis within intervention trials. There is a need for further intervention studies in this space to be conducted as rigorous trials of resilience-focussed approaches based on such evidence of association, with clearly posited mechanisms of change, and inclusive of analysis of differential intervention effects. The suggested implications for research made in this conceptual analysis will aid in improving the quality of the evidence base relevant to the fostering of resilience and prevention of mental health problems in children and adolescents.

Life Course Nature Exposure and Mental Health Outcomes: A Systematic Review and Future Directions

Recently, an emerging body of literature has examined the relationships between early life nature exposure and mental health in later life; however, no critical synthesis yet exists regarding the extent and strength of these relationships. This study presents the first systematic review of studies in this growing area. Following the PRISMA framework, we searched six databases (i.e., Scopus, Web of Science, MEDLINE, Embase, PsycINFO, and CINAHL); conducted identification, screening, eligibility, and inclusion analyses; and identified a final set of 29 articles. The review set comprises primarily longitudinal studies, with several cross-sectional studies using retrospective measures of childhood nature exposure. The majority of included studies were published between 2016 and 2020 and conducted in Europe and North America. Five domains of mental health outcomes are associated with early-life nature exposure: incidence of mental disorders, psychiatric symptoms and emotions, conduct problems in children, cognitive function, and subjective well-being. The evidence lends support to an overall beneficial role of early nature exposure on mental health, although inconsistencies are reported. Taken together, the evidence does not suggest that exposure at any given life stage is more saliently associated with mental health outcomes than at others. We discuss the validity concerns and methodological remedies and offer directions for future research.

Parental Behavioral Control and Bullying and Victimization of Rural Adolescents in China: The Roles of Deviant Peer Affiliation and Gender

Bullying and victimization (BAV) have been widely studied, but the potential mechanism of parental behavioral control (PBC) on bullying and victimization in Chinese adolescents has not been explored. This study aimed to examine a moderated mediation model for the association between PBC and BAV mediated by deviant peer affiliation (DPA) and moderated by gender. A total of 3779 adolescents (N_boy = 1679, M_age = 14.98 years, SD = 0.95) from southwest China has completed the Peer Bullying, Peer Victimization, PBC, and DPA questionnaires. The results indicated that: (1) PBC significantly predicted adolescents’ BAV (−12%); (2) DPA mediated the effect of PBC on BAV only for those adolescents who were both bullies and victims; (3) the mediating role of DPA was moderated by gender only in the relationship between PBC and victimization, with a relatively stronger effect in girls than in boys.

Editors' Comments on the Special Issue "Social Determinants of Mental Health"

Mental disorders are one of the greatest public health concerns of our time, and they are affected by social factors. To reduce the considerable burden of mental disorders, more global and systematic knowledge of the social determinants of mental health is necessary. This paper presents the results of the 27 studies included in the International Journal of Environmental Research and Public Health Special Issue, “Social Determinants of Mental Health”. The studies are grouped into four broad categories: social inclusion and mental health, young people’s mental health, mental health at work, and mental health service users. The results cover different countries, age populations, settings, and methodologies. Finally, the main findings on the relationship between social determinants and mental health are presented and summarized.

Bullying Victimization and Friendship as Influences on Sleep Difficulty among Brazilian Adolescents

Bullying victimization is associated with poor health-related outcomes, including sleeping problems. The present study aimed to investigate the impact of bullying victimization on sleep difficulty, and the moderating effect of the number of close friends on this association, also exploring differences across genders. The study was based on a nationally-representative survey on adolescent health conducted in Brazilian schools, involving a total of 109,104 participants, enrolled at the 9th year in 2012. The measures used in the analysis included socio-demographic characteristics, bullying victimization, sleep difficulty, and number of close friends. In the multilevel models, reporting more peer victimization was associated with more sleep difficulties (b = .18, t = 50.17, p < .05), with girls reporting more sleep difficulties in association with peer victimization than boys. Reporting having more friends was inversely linked to sleep difficulties (b = -.08, t = -15.26, p < .05), and the association between peer victimization and sleep difficulties was significantly buffered by the number of friends. Moreover, in a three way interaction, there was a marginally significant difference in the effect of friends on the link between victimization and sleep difficulties between boys and girls (b = .02, t = 1.86, p = .06), with the buffering effect of friendships being negligible among girls as opposed to boys. The results indicate a significant association between bullying victimization and sleep difficulties, which seems to be more pronounced among girls, also suggesting that the number of close friends may buffer this association, mainly for boys.

Adolescents' Bipolar Experiences and Suicide Risk: Well-being and Mental Health Difficulties as Mediators

Bipolar disorder is usually accompanied by a high suicide risk. The main aim was to identify the risk and protective factors involved in suicide risk in adolescents with bipolar experiences. Of a total of 1506 adolescents, 467 (31%) were included in the group reporting bipolar experiences or symptoms, 214 males (45.8%) and 253 (54.2%) females. The mean age was 16.22 (SD = 1.36), with the age range between 14 and 19. Suicide risk, behavioral and emotional difficulties, prosocial capacities, well-being, and bipolar experiences were assessed through self-report. Mediation analyses, taking gender as a moderator and controlling age as a covariate, were applied to estimate suicide risk. The results indicated that the effect of bipolar experiences on suicide risk is mediated by behavioral and emotional difficulties rather than by prosocial behavior and subjective well-being. Specifically, emotional problems, problems with peers, behavior problems, and difficulties associated with hyperactivity were the most important variables. This relationship was not modulated by gender. However, the indirect effects of some mediators varied according to gender. These results support the development of suicide risk prevention strategies focused on reducing emotional difficulties, behavioral problems, and difficulties in relationships with others.

The Impact of Childhood Left-Behind Experience on the Mental Health of Late Adolescents: Evidence from Chinese College Freshmen

A paucity of public service afforded to migrant workers often begets a wide range of social problems. In China, hundreds of millions of migrant worker parents have to leave children behind in their hometowns. This paper investigated the long-term effects of the childhood experience of being left behind on the mental well-being of late adolescents. Mandatory university personality inventory (UPI) surveys (involving psychosomatic problems such as anxiety, depression, and stress) were conducted at a university in Jiangsu, China, during 2014–2017. The study sample consisted of 15,804 first-year college students aged between 15 and 28 years. The PSM method and the OLS regression model were employed. Controlling for the confounding factors (gender, age, single-child status, hometown location, ethnicity, and economic status), our empirical investigation demonstrated that childhood left-behind experience significantly worsened the mental health of the study sample, increasing the measure of mental ill-being by 0.661 standard deviations (p < 0.01). Moreover, the effects were consistently significant in subsamples divided by gender, single-child status, and hometown location; and the effects were greater for females, single-child students, and urban residents.

Levels of Physical Activity and Mental Health in Adolescents in Ireland

The benefits of physical activity for the physical health of individuals are well documented. Less is known about the benefits of physical activity for mental health. This paper explores the associations between physical activity and positive mental health and mental health problems. The paper utilises data collected from a representative sample of 10-17-year-old adolescents in Ireland. Physical activity in the study is measured using moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA). Mental health was measured using the Cantril Leader of Life Satisfaction, the WHO-5 index, Mental Health Inventory (MHI-5) and the Health Behaviour in School-Aged Children (HBSC) Symptom Checklist (HBSC-SCL). Data were analysed using bivariate (Pearson Correlation, t-test, one-way ANOVA) and multivariate (two-way ANOVA, ordinary least squares (OLS) regressions) analyses. In total, 8636 adolescents were included in this analysis. Higher participation in physical activity was associated with higher scores on the positive mental health indicators and lower scores on the mental health problems indicators. When modelled together, VPA was a stronger predictor of mental health than MVPA, especially in girls. For example, standardised beta coefficients for predicting MHI-5 were -0.09 for MVPA (p < 0.001) and -0.13 for VPA (p < 0.001) To our knowledge, this is the first study that looks at levels of physical activity as well as both positive mental health and mental health problems. The study highlights the need to encourage and enable adolescents, and especially girls, to participate in vigorous exercising as way of promoting positive mental health.

Unhealthy life habits associated with self-induced vomiting and laxative misuse in Brazilian adolescents

Adolescence is a stage in life characterized by important social, cognitive, and physical changes. Adolescents are vulnerable to various psychosocial disorders, including eating disorders. We aimed to investigate the association between unhealthy habits, sociodemographic characteristics, and the practice of self-induced vomiting or laxative misuse in a representative sample of Brazilian adolescent girls and boys. Data from 102,072 students who participated in the National Adolescent School-based Health Survey were analyzed using the dependent variable: presence or absence of self-induced vomiting and/or laxative misuse; independent variables: consumption of unhealthy and high-calorie food items, age during first sexual intercourse, and the use of tobacco, alcohol, and/or illicit drugs. Associations between exposure and outcome were estimated using Poisson's regression models stratified by sex, and including region, school, age group, and mother's educational history as adjustment variables. Eating ultra-processed foods and age during first sexual intercourse were associated with self-induced vomiting and laxative misuse only for girls; all other variables (consuming unhealthy foods and using legal or illicit substances) were associated with these behaviors for both sexes after applying adjustment variables. Early interventions focusing on changing unhealthy behaviors may prevent development of eating disorders in adolescents. Our findings demonstrate a strong association of many unhealthy habits with laxative misuse and self-induced vomiting practices in Brazilian adolescents.

Associated factors and sex differences in condom non-use among adolescents: Brazilian National School Health Survey (PeNSE)

Background

Condom non-use among sexually active adolescents is a major cause of unintended pregnancy and sexually transmitted infections. In order to promote condom use, it is essential to understand factors associated with condom non-use.

Aim

Our aim was to evaluate sex differences and associated factors of condom non-use based on the nationally representative Brazilian National School Health Survey.

Methods

The study participants were 100,962 adolescents 13–18 years old, 9th graders from both public and private schools throughout Brazil. The following factors were considered as explanatory group variables for the outcome of condom non-use among adolescents: school and health service, sexual behavior, substance use, and self-reported body and health perception. Poisson regression model was performed.

Results

Of the total students, 28% (n = 28,157) had had sexual intercourse at least once. (boys, 37.1%; girls, 19.5%). Of these, 69.2% had used condoms the last time they had intercourse (girls: 68%; boys: 69.9%). The variables associated with condom non-use for both sexes were not having accessed a health service or approached a health professional for health-related care; not having received pregnancy prevention counseling or guidance on AIDS or STI prevention at school; early sexual initiation; no additional contraception method; substance use; feeling alone; not being satisfied with their own body; feeling fat or thin; and poor self-reported health. The number of sexual partners was also associated with condom non-use; however, contrasting behavior was indicated between sexes. A higher number of sexual partners indicated less use of condoms among girls, while for boys, a higher number of sexual partners indicated higher condom use.

Conclusion

High condom non-use appears to be associated with lack of health care access and sexual health education, poor sexual practices, substance use, and poor self-perception, indicating areas for health promotion programs.

Family and School Context: Effects on the Mental Health of Brazilian Students

Mental health during adolescence can affect an individual’s long-term quality of life. However, the effects of family and school contexts on students’ mental health have been little explored. This study aims to analyze the relationships between family and school life and feelings of loneliness and trouble sleeping owing to worries in adolescents. The data from this cross-sectional study were obtained from Brazil’s National School Health Survey (PeNSE), which obtained its data through questionnaires. This study’s sample consisted of 102,072 ninth-grade students aged between 11 and 19 years, 52,782 (51.7%) of whom were female, enrolled in public and private schools throughout Brazil. The methodology consisted of an analysis using the Poisson regression model. Regarding the family context, mental health issues were associated with hunger, distant relationships with parents, and family violence. Regarding the school context, feelings of loneliness and trouble sleeping were associated with poor peer relationships, insecurity at school, and schools in more violent areas. This study contributes to the elaboration of public policies aimed at bringing awareness to family members and school bodies that indicators of mental health in adolescents are influenced by the quality of bonds established within these environments.
