Suicidal behavior among school-going adolescents in Bangladesh: findings of the global school-based student health survey

Suicidal behaviors among high school graduates with preexisting mental health problems: a machine learning and GIS-based study

BACKGROUND

Suicidal behavior among adolescents with mental health disorders, such as depression and anxiety, is a critical issue. This study explores the prevalence and predictors of past-year suicidal behaviors among Bangladeshi high school graduates, employing both traditional statistical and machine learning methods.

AIMS

To investigate the prevalence and predictors of past-year suicidal behaviors among high school graduates with mental health disorders, evaluate the effectiveness of various machine learning models in predicting these behaviors, and identify geographical disparities.

METHODS

A cross-sectional survey was conducted with 1,242 high school graduates (54.1% female) in June 2023, collecting data on sociodemographic characteristics, mental health status, sleep patterns, and digital addiction. Statistical analyses were performed using SPSS, while machine learning and GIS analyses were conducted with Python and ArcMap 10.8, respectively.

RESULTS

Among the participants, 29.9% reported suicidal ideation, 15.3% had suicide plans, and 5.4% attempted suicide in the past year. Significant predictors included rural residence, sleep duration, comorbid depression and anxiety, and digital addiction. Machine learning analyses revealed that permanent residence was the most significant predictor of suicidal behavior, while digital addiction had the least impact. Among the models used, the CatBoost model achieved the highest accuracy (69.42% for ideation, 87.05% for planning, and 94.77% for attempts) and demonstrated superior predictive performance. Geographical analysis showed higher rates of suicidal behaviors in specific districts, though overall disparities were not statistically significant.

CONCLUSION

Enhancing mental health services in rural areas, addressing sleep issues, and implementing digital health and community awareness programs are crucial for reducing suicidal behavior. Future longitudinal research is needed to better understand these factors and develop more effective prevention strategies.

Patterns of maternal adverse childhood experiences and the intergenerational association of preschool children's emotional and behavioral problems

Introduction

Children of whose mothers exposed to adverse childhood experiences (ACEs) are at increased risk for developmental problems. This study aims to investigate the relationship between types and patterns of maternal ACEs and preschool children's emotional and behavioral problems (EBPs) in China, and to explore gender differences associated with these problems.

Methods

In this cross-sectional study, we selected 9,647 children from 36 preschools in three cities of Anhui province, China. Questionnaires were used to report the details of maternal ACEs and children's EBPs. We used the latent class analysis (LCA) to identify "patterns" in the types of maternal ACEs. Binomial logistic regressions was performed to examine the relationship between types and patterns of maternal ACEs and preschoolers' EBPs.

Results

Latent class analysis (LCA) revealed four different classes of maternal ACEs. Logistic regression analysis showed that compared with the low ACEs class, children of mothers in the high abuse and neglect class had the highest risk of developing EBPs (OR = 5.93, 95%CI: 4.70-7.49), followed by moderate ACEs class (OR = 2.44, 95%CI: 1.98-3.00), and high household dysfunction class (OR = 2.16, 95%CI: 1.19-3.90). We found gender differences in the effects of high abuse and neglect/moderate ACEs class and maternal childhood physical abuse/neglect on children's EBPs, which had a stronger impact on EBPs in boys than girls (P<0.05).

Discussion

This study supports and refines existing research that confirms an intergenerational association between types and patterns of maternal ACEs and children's EBPs in a large Chinese sample, so as to provide references for the early prevention and control of children's EBPs.

The Association Between Child Maltreatment and Loneliness Across the Lifespan: A Systematic Review and Multilevel Meta-Analysis

While there is evidence that child maltreatment is positively associated with loneliness, the strength of this association is not yet clear. It is also unclear whether the magnitude and statistical significance of this association varies across groups of individuals. Therefore, this meta-analysis examines whether there are differences in loneliness between individuals with and without maltreatment histories, and which factors may influence the association between child maltreatment and loneliness. A three-level meta-analysis was conducted on 52 studies reporting 116 effect sizes (N = 1,705,493; Mage = 30.93; 49.6% females). Results showed a medium overall effect (g = 0.45, p < .001, 95% CI [0.36, 0.53]), indicating that individuals with maltreatment histories, on average, feel lonelier than individuals without maltreatment histories. Moderator analyses showed that effect sizes were larger for emotional abuse and emotional neglect as compared to other types of child maltreatment and decreased when participants were older at the time of loneliness assessment. These findings suggest that individuals with maltreatment histories, especially those who have been emotionally abused and/or emotionally neglected, are vulnerable to experiencing loneliness across the lifespan. The results also suggest that feelings of loneliness warrant attention in prevention and intervention programs for individuals with maltreatment histories.

Suicide ideation and psychotropic recreational drug use by adolescents: a systematic review and meta-analysis

BACKGROUND

Adolescence is characterized by complex and dynamic changes, often involving experimentation, including the use of psychotropic substances. Although it is well-established that recreational psychotropic drugs are associated with suicide ideation in adults, evidence of this association in adolescents remains limited.

OBJECTIVE

To investigate the relationship between suicide ideation and psychotropic recreational drug use among adolescents.

DESIGN AND SETTING

Systematic review with meta-analysis developed at Universidade Federal de Uberlândia (UFU) and Universidade Estadual de Campinas (UNICAMP), Brazil.

METHODS

A search across eight electronic databases for observational studies, without language or publication year restrictions, was conducted. The Joanna Briggs Institute tool was used to assess the risk of bias. Random-effects meta-analyses and odds ratios were used to measure the effects.

RESULTS

The search yielded 19,732 studies, of which 78 were included in the qualitative synthesis and 32 in the meta-analysis. The findings indicated that suicidal ideation was 1.96 times more likely (95% confidence interval, CI = 1.47; 2.61) for adolescents who used some drug recurrently and 3.32 times more likely (95%CI = 1.86; 5.93) among those who abused drugs. Additionally, adolescents who used cannabis were 1.57 times more likely (95%CI = 1.34; 1.84) to experience suicide ideation compared with non-users, while cocaine users had 2.57 times higher odds (95%CI = 1.47; 4.50).

CONCLUSIONS

Psychotropic recreational drug use is associated with suicidal ideation among adolescents regardless of current or previous use, abuse, or type of substance used.

Social support, distress, stress, anxiety, and depression as predictors of suicidal thoughts among selected university students in Bangladesh

This study examines the association of perceived social support with suicidal thoughts among a young adult sample of university students and estimates the degree to which perceived stress, distress, anxiety, and depression may explain the association. A cross-sectional survey was conducted from June to September 2022 among 642 students, selected using the probability proportional to size procedure, at a large university in Bangladesh. We used the Multidimensional Scale of Perceived Social Support (MSPSS) to measure support. The Impact of Events Scale-Revised (IES-R), the Perceived Stress Scale (PSS-10), the Generalized Anxiety Disorders (GAD-7) scale, and the Patient Health Questionnaire (PHQ-9) were used to assess distress, stress, anxiety, and depression. The association between social support and suicidal thoughts was examined using multivariable logistic regression models. Mediation analyses were carried out using the Karlson, Holm, and Breen (KHB) method. We found that perceived social support was associated with lower odds of suicidal thoughts after controlling for other variables (adjusted odds ratio = 0.94; 95% confidence interval = 0.92-0.96). Mediation analysis showed that, after adjusting for potential confounders, the mediating effects among the total effect of perceived social support on suicidal thoughts were 56.1%, 20.8%, 22.5%, 38.8%, and 50.9% for all mental disorders together and four specific adverse mental health outcomes, i.e., perceived distress, stress, anxiety, and depression, respectively. This study demonstrates that perceived social support reduces the likelihood of suicidal thoughts among university students, and mental disorders have a partial mediating effect on the association. Suicide prevention and mental health promotion efforts among university students should consider encouraging students to build and strengthen a strong social support network.

Suicide Ideation within and outside the Perinatal Period: An Exploration of Interpersonal Factors from a Maternal Cohort in Rural Pakistan to Improve Intervention Targeting

OBJECTIVE

Suicide accounts for substantial mortality in low-resourced settings and contributes to nearly 20% of maternal deaths. In Asia, interpersonal conflict is a salient factor that contributes to suicidal thoughts and actions, yet limited research has been done to explore the type and timing of such conflicts and a woman's accompanying social support. Identifying such risk factors can inform improved efforts to identify who to target for psychosocial interventions.

METHODS

Using the Bachpan Cohort study of mothers in Pakistan (n = 1154), we examined the prevalence and interpersonal influences on SI within the past two weeks of pregnancy and then at 3, 6, and 24 months after birth. Using hierarchical mixed effects models, we explored the separate and combined associations of interpersonal factors [e.g., social support, interpersonal conflict, isolation, and past year intimate partner violence (IPV)] on SI at each timepoint.

RESULTS

SI prevalence was highest in pregnancy (12.2%) and dropped to 5% throughout two years postpartum. The interpersonal conflict was independently associated with increased odds of SI in pregnancy and 24 months postpartum. IPV was associated with increased SI in pregnancy and 24 months postpartum. Isolation was not associated with SI at any timepoint. Perceived social support remained a robust independent factor associated with reduced SI at all timepoints.

CONCLUSION

In addition to screening and deploying interventions for perinatal women with depression, targeting interventions for those who also experience interpersonal conflict, including intimate partner violence, may significantly reduce suicidal thoughts and related sequelae. Social support is a viable and potentially powerful target to reduce the burden of suicide among women.HIGHLIGHTSSuicidal ideation prevalence was higher in pregnancy compared to postpartum.Perceived social support was independently associated with reduced suicidal ideation.Interventions addressing suicide must attend to women's family and social context.

Factors associated with mental health among Hong Kong children: A population-based study of 4884 individuals

BACKGROUND

This cross-sectional study aimed to investigate the association between negative mental health conditions and demographic characteristics, socioeconomic background and health-related parameters in both Hong Kong's primary and secondary school students.

METHODS

A self-administrated survey was conducted and investigated the prevalence of negative mental health conditions (psychological stress, depression and suicidality) in students from 30 primary schools and 25 secondary schools in Hong Kong in 2017. The Kessler Psychological Distress Scale (K6) was chosen as the instrument to evaluate non-specific psychological distress. Depression was evaluated using the prolonged feeling of despair as a proxy. Suicidality was measured by four questions on whether they had ever intentionally injured themselves, seriously considered attempting suicide, planned how they would attempt suicide and had attempted suicide. Multiple logistic regression models examined the explanatory factors' association with mental health conditions after adjusting for confounding, using the enter method.

RESULTS

A total of 4884 responses were collected. It is found that both very high and low parent expectations were risk factors for multiple conditions, namely suicidality and psychological distress among primary school students, and psychological distress among secondary school students. As for primary school students, the experience of being bullied was a significant risk factor for all conditions. A significant association was found between having one's own bedroom and suicidality amongst primary school students; whilst having three close friends or more and higher life satisfaction levels were significantly associated with a lower risk of negative mental health conditions among secondary school students.

CONCLUSIONS

It was found that having one's own bedroom was a risk factor for suicidality among primary school student. Parents should be alert to the risky behaviours of children, have more involvement in children's daily life and build a supportive and caring family environment for children. For secondary school students, as the importance of friends is greatly increased, teachers should encourage students to engage in extra-curricular activities in school.

Prevalence of Suicidal Behavior Among Students in South-East Asia: A Systematic Review and Meta-Analysis

OBJECTIVES

Estimation of rates of suicidal behaviors (ideation, plan, and attempt) would help to understand the burden and prioritize prevention strategies. However, no attempt to assess suicidal behavior among students was identified in South-East Asia (SEA). We aimed to assess the prevalence of suicidal behavior (ideation, plan, and attempt) among students in SEA.

METHODS

We followed PRISMA 2020 guidelines and registered the protocol in PROSPERO (CRD42022353438). We searched in Medline, Embase, and PsycINFO and performed meta-analyses to pool the lifetime, 1-year, and point prevalence rates for suicidal ideation, plans, and attempts. We considered the duration of a month for point prevalence.

RESULTS

The search identified 40 separate populations from which 46 were included in the analyses, as some studies included samples from multiple countries. The pooled prevalence of suicidal ideation was 17.4% (confidence interval [95% CI], 12.4%-23.9%) for lifetime, 9.33% (95% CI, 7.2%-12%) for the past year, and 4.8% (95% CI, 3.6%-6.4%) for the present time. The pooled prevalence of suicide plans was 9% (95% CI, 6.2%-12.9%) for lifetime, 7.3% (95% CI, 5.1%-10.3%) for the past year, and 2.3% (95% CI, 0.8%-6.7%) for the present time. The pooled prevalence of suicide attempts was 5.2% (95% CI, 3.5%-7.8%) for lifetime and 4.5% (95% CI, 3.4%-5.8%) for the past year. Higher rates of suicide attempts in the lifetime were noted in Nepal (10%) and Bangladesh (9%), while lower rates were reported in India (4%) and Indonesia (5%).

CONCLUSIONS

Suicidal behaviors are a common phenomenon among students in the SEA region. These findings call for integrated, multisectoral efforts to prevent suicidal behaviors in this group.

The prevalence of suicidal behaviour and its associated risk factors among school-going adolescents resident in the United Arab Emirates

Suicidal behaviour which includes suicidal ideation, having a plan to commit suicide and suicide attempts remains a global public health issue as it substantially impacts adolescent health and wellbeing. Suicidal behaviour, however, remains understudied in Middle Eastern contexts. This study analysed data from the 2016 Global School-based Student Health Survey collected in the United Arab Emirates (UAE). A sample of 5826 adolescents aged between 11 and 18 years were sampled. Potential risk factors associated with an elevated risk for engagement in suicidal behaviour were examined. These factors were stratified into categories for analysis (demographics, psychosocial, risky health, and socio-environmental). The age-adjusted prevalence of suicidal behaviour amongst the school-going adolescent population in the UAE was 54%. Analyses indicated that elevated risk was significantly associated with anxiety difficulties, the experience of loneliness, and amongst those who smoked tobacco. None of the socio-environmental factors emerged as significant. A dose-dependent relationship was evident in that the degree of risk that was evident appeared to compound as the number of adverse risk factors increased. The data suggest that suicidal behaviour may be highly prevalent in this location. Findings highlight the immense need to develop preventative interventions, some of which may be school-delivered and targeted at parents. Our findings provide initial indications as to which risk factors could be targeted for remediation in developing these interventions.

Spatial pattern and influential factors for early marriage: evidence from Bangladesh Demographic Health Survey 2017-18 data

BACKGROUND

Early marriage is highly prevalent in Bangladesh. It is linked with a range of adverse outcomes, including maternal and child mortality. However, research on regional variations and factors associated with early marriage is scarce in Bangladesh. This study aimed to explore the geographical variations and predictors of early marriage in Bangladesh.

METHODS

Data of women aged 20-24 in the Bangladesh Demographic and Health Survey 2017-18 were analysed. The occurrence of early marriage was the outcome variable. Explanatory variables were several individual-, household- and community-level factors. Geographical hot spots and cold spots of early marriage were first determined using Global Moran's I statistic. Multilevel mixed-effect Poisson regression was used to determine the association of early marriage with individual-, household-, and community-level factors.

RESULTS

Almost 59% of women aged 20-24 reported they were married before reached 18. The hotspots of early marriage were mainly concentrated in Rajshahi, Rangpur and Barishal, and the cold spots were in Sylhet and Chattogram divisions. The prevalence of early marriage was lower among higher educated (adjusted prevalence ratio (aPR): 0.45; 95% CI: 0.40, 0.52), and non-Muslim women (aPR: 0.89; 95% CI: 0.79, 0.99) than their counterparts. Higher community-level poverty was significantly associated with early marriage (aPR, 1.16; 95% CI: 1.04, 1.29).

CONCLUSION

The study concludes that promoting girls' education, awareness-building programs about the adverse effects of early marriage and proper application of the child marriage restraint act, particularly in disadvantaged communities are recommended.

Suicidal ideation and attempts among high school students of war- affected area at Woldia town, Northeast, Ethiopia, 2022

BACKGROUND

Suicidal ideation and attempts usually occur during adolescence time, and living in war- affected area make the problem more predominate and severe. To the best of our knowledge, there were no studies done among high school students who live in war affected areas in Ethiopia.

OBJECTIVE

We assessed the prevalence and factors associated with suicide ideation and suicide attempts among high school students of war- affected area at Woldia town, Northeast, Ethiopia.

METHODS

School based cross-sectional study was conducted from May 23 to June 08, 2022.Data were collected from high school students in Woldia town, Ethiopia. Pretested, self-administered Amharic-language questionnaire was used to collect the data. Bivariable and multivariable logistic regression was used to identify the independent factors associated with suicide ideation and attempt.

RESULTS

A total of 668 of the 707 sampled students participated in the study (94.5% response rate). The prevalence of suicidal ideation and attempts among high school students in Woldia town was 16.29% and 12.87%, respectively. In the multivariable analysis, poor social support(AOR = 2.86, 95% CI:1.49, 5.46), posttraumatic stress disorder (AOR = 2.15, 95% CI:1.20, 3.85), family history of suicide(AOR = 3.94, 95% CI:2.21, 7.04), anxiety(AOR = 3.45, 95% CI:1.72, 6.89), and depression (AOR = 2.31, 95% CI:1.24, 4.33) were factors significantly associated with suicide ideation, and poor social support(AOR = 2.75, 95% CI:1.38, 5.47), depression (AOR = 4.27, 95% CI:2.10, 8.67) and being a female sex (AOR = 2.12, 95% CI:1.22, 3.69) were factors significantly associated with suicidal attempt.

CONCLUSIONS AND RECOMMENDATIONS

This study revealed that at least one in six and one in eight of the students had suicidal ideation and attempt, respectively. Therefore, we recommend that Ministry of Education shall work with Ministry of Health to extend and implement mental health services in high schools and provide social support to those students who need the services in order for the prevention of suicidal ideation and attempts.

Co-occurrence patterns of adverse childhood experiences and their associations with non-suicidal self-injury and suicidal behaviors and gender difference among middle school students: A three-city survey in China

BACKGROUND

Previous research has found increasing evidence of adverse childhood experiences (ACEs) leading to non-suicidal self-injury (NSSI) and suicidal behaviors. Most studies have focused on a certain type or timing of ACEs or the patterns of multiple types; however, few of them have examined the patterns of ACEs combined types and timing and the gender differences in the association between ACEs and self-harming behaviors.

METHODS

A cross-sectional survey was conducted in three Chinese cities from November 2020 to May 2021. We asked 16,853 middle school students to anonymously complete a questionnaire to provide the details of their own ACEs and NSSI or suicidal behaviors.

RESULTS

Latent class analysis identified four classes: high ACEs (10 %), high abuse/neglect (20.3 %), moderate ACEs (26.7 %) and low ACEs (43 %). Logistic regression models demonstrated that students in the high ACEs, high abuse/neglect and moderate ACEs subgroups were more likely to engage in NSSI and suicidal behaviors than students with low ACEs. Compared with boys, girls had a higher probability of engaging in NSSI and suicidal behaviors when exposed to the same level of ACEs.

CONCLUSION

Co-occurrence of ACEs is associated with high risk of NSSI and suicidal behaviors. Our findings recognized the most dangerous patterns and latent class membership, which supply the evidence for policy makers to adopt preventive measures to protect high-risk individuals. Strategies to relieve the impact of ACEs, especially on girls, need to be considered comprehensively.

LIMITATIONS

The study was limited by cross-sectional design, as causality could not be confirmed. In addition, because our survey was retrospective, potential recall bias can not be ignored.

In-school adolescents’ loneliness, social support, and suicidal ideation in sub-Saharan Africa: Leveraging Global School Health data to advance mental health focus in the region

Introduction

Adolescent and youth mental health problems are increasingly becoming an area of concern in global health. Young people in sub-Saharan Africa experience significant adversities and systemic challenges despite technological advancements and demographic transition that the region is experiencing. We examined the nexus between experiences of loneliness, low social support, and presence of suicidal ideation among in-school adolescents in sub-Saharan Africa.

Method

A total of 19,119 in-school adolescents from eight countries in sub-Saharan Africa were included in this study. Suicidal ideation was the main outcome variable and loneliness, and social support were the explanatory variables. Percentages were used to summarise the prevalence of suicidal ideation, loneliness, and social support among the in-school adolescents. A multivariable binary logistic regression analysis was later used to determine the association between suicidal ideation and the explanatory variables and covariates using Stata v16. Four models were tested using the regression analysis. We presented the regression results using adjusted odds ratios (aOR), with their respective 95% confidence intervals (CIs).

Results

Overall, the past year prevalence of loneliness, peer support, one or more close friends, and suicidal ideation were 10%, 33.4%, 90.1%, and 14.5%, respectively. In-school adolescents who felt lonely (aOR = 1.88, 95% CI = 1.69, 2.09) were more likely to experience suicidal ideation. However, those who received peer support (aOR = 0.89, 95% CI = 0.82, 0.97) and had one or more close friends (aOR = 0.77, 95% CI = 0.68, 0.86) were less likely to experience suicidal ideation.

Conclusion

These results point to the significant roles of loneliness, and lack of social support, in understanding suicidal ideations. Countries in sub-Saharan Africa need to improve child and adolescent mental health policies and programmes to respond to these risk factors and mental health challenges. Programmes with a differential focus on the needs of males and females, younger and older adolescents will be important in the future.

Rate and Associated Factors of Suicidal Behavior among Adolescents in Bangladesh and Indonesia: Global School-Based Student Health Survey Data Analysis

OBJECTIVE

Suicidal behavior among adolescents is a major public health problem that is understudied in South East Asian Muslim-majority countries. We aimed to investigate the rate and associated factors of suicidal behavior among adolescents in Bangladesh and Indonesia.

METHODS

The Global School-based Student Health Survey data of Bangladesh and Indonesia were used in this study. The data consist of a total of 9052 school-aged students from Bangladesh (2570, 28.4%) and Indonesia (6482, 71.6%). Suicidal behavior was assessed using three questions that measure suicidal ideation, suicidal plan, and suicidal attempts.

RESULTS

The overall rate of suicidal behavior (suicidal ideation, suicidal plan, and suicidal attempts) was 8.8%, and no significant difference between the two countries (8.9% in Bangladesh and 8.7 in Indonesia) was observed (p=0.81). Factors that independently increased the likelihood of suicidal behavior include female gender, missed class, physical fight four times or more, experienced bullying, anxiety, loneliness, rarely eating fruit, current alcohol use, and sedentary behavior (p < 0.05). Meanwhile, factors that independently decreased the likelihood of suicidal behavior include parental supervision and having close friends, either one, two, three persons, or more (p < 0.05).

CONCLUSION

The study revealed rates and risk factors of suicidal behaviors among the school-going adolescents of two Muslim-majority countries in South East Asia. Prevention strategies should be considered guided by the risk factors for school-going adolescents.

Factors associated with single and multiple suicide attempts in adolescents attending school in Argentina: national cross-sectional survey in 2018

BACKGROUND

Factors associated with single suicide attempts (SSA) and multiple suicide attempts (MSA) may differ.

AIMS

The study aimed to assess the factors associated with MSA in adolescents with a history of suicide attempts during the past 12 months in Argentina.

METHOD

National cross-sectional data from the Global School-based Student Health Survey in Argentina in 2018 were analysed. Students who reported having a history of suicide attempts in the past 12 months were included in the final sample (n = 8507). Students with MSA were compared with students with an SSA through multiple logistic regression.

RESULTS

In a subsample of adolescents attending school (mean age 14.8 years, s.d. = 1.3), 59.4% had an SSA and 40.6% had MSA in the past 12 months. In the final adjusted logistic regression model, compared with participants with SSA, both male and female students with MSA more frequently had no close friends, reported feeling more lonely and had more anxiety-induced sleep disturbances. Furthermore, among female participants, having been physically attacked, having participated in physical fights, low parental support, current tobacco use and lifetime amphetamine use were associated with MSA. Among male students, multiple sexual partners were associated with MSA. Furthermore, among both boys and girls, compared with participants without psychosocial distress, participants with one, two, three or more psychosocial distress factors had higher odds of MSA. Compared with students with one or two social or environmental risk factors, students with seven or eight social or environmental risk factors had higher odds of MSA; compared with students who had zero or one health risk behaviours, students with six or more health risk behaviours had higher odds of MSA.

CONCLUSIONS

Psychosocial distress (anxiety-induced sleep disturbance, having no close friends and loneliness) increased the odds of MSA among both sexes. The odds of MSA were increased by interpersonal violence, low parental support and substance use among girls, and by having multiple sexual partners among boys. This suggests the potential relevance of these variables in identifying multiple suicide attempters among adolescents attending school in Argentina.

Suicidal behavior in Mexican adolescents: A test of a latent class model using two independent probability samples

Suicidal behavior is a serious health issue that affects the adolescent population and that may be prevented through evidence-based approaches. There are many risk factors involved in suicidal behavior, but there are few studies encompassing the complex relationships between them. This study tested the similarity between two latent class models from two different epidemiological samples of middle-school students and evaluated if the multinomial regression model replicated the associations between the classes and the psychosocial variables. Data of 4013 adolescents from the Mexican states of Campeche and Querétaro were included in LCA to characterize suicide behavior and associated factors. The most likely latent class membership was used as the outcome in multinomial regression models. The model with data from Querétaro was consistent with the previous LC model from Campeche. The four latent classes were nearly identical for both populations and can be defined as follows: 1) "No Problems," included 73% of the adolescents; 2) "Drug Use Only," comprised 7% of the adolescents; 3) "Suicidal Behavior, No Depression," captured 8% of the adolescents (25% reported binge drinking in the past month, 50% self-inflicted injuries, and 43% low-lethality suicide attempt); 4) "Depression and Suicidal Behavior," comprised 12% of the sample (66% met criteria for Major Depressive Episode, 28% reported binge drinking in the past month, and 11% had a high-lethality suicide attempt). The congruence between the models and the consistency with identified factors highlight the need for appropriate and effective prevention strategies to minimize risk factors and reinforce protective factors in the adolescent population.

The prevalence of loneliness across 113 countries: systematic review and meta-analysis

OBJECTIVES

To identify data availability, gaps, and patterns for population level prevalence of loneliness globally, to summarise prevalence estimates within World Health Organization regions when feasible through meta-analysis, and to examine temporal trends of loneliness in countries where data exist.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Embase, Medline, PsycINFO, and Scopus for peer reviewed literature, and Google Scholar and Open Grey for grey literature, supplemented by backward reference searching (to 1 September 2021) ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Observational studies based on nationally representative samples (n≥292), validated instruments, and prevalence data for 2000-19. Two researchers independently extracted data and assessed the risk of bias using the Joanna Briggs Institute checklist. Random effects meta-analysis was conducted in the subset of studies with relatively homogeneous research methods by measurement instrument, age group, and WHO region.

RESULTS

Prevalence data were available for 113 countries or territories, according to official WHO nomenclature for regions, from 57 studies. Data were available for adolescents (12-17 years) in 77 countries or territories, young adults (18-29 years) in 30 countries, middle aged adults (30-59 years) in 32 countries, and older adults (≥60 years) in 40 countries. Data for all age groups except adolescents were lacking outside of Europe. Overall, 212 estimates for 106 countries from 24 studies were included in meta-analyses. The pooled prevalence of loneliness for adolescents ranged from 9.2% (95% confidence interval 6.8% to 12.4%) in South-East Asia to 14.4% (12.2% to 17.1%) in the Eastern Mediterranean region. For adults, meta-analysis was conducted for the European region only, and a consistent geographical pattern was shown for all adult age groups. The lowest prevalence of loneliness was consistently observed in northern European countries (2.9%, 1.8% to 4.5% for young adults; 2.7%, 2.4% to 3.0% for middle aged adults; and 5.2%, 4.2% to 6.5% for older adults) and the highest in eastern European countries (7.5%, 5.9% to 9.4% for young adults; 9.6%, 7.7% to 12.0% for middle aged adults; and 21.3%, 18.7% to 24.2% for older adults).

CONCLUSION

Problematic levels of loneliness are experienced by a substantial proportion of the population in many countries. The substantial difference in data coverage between high income countries (particularly Europe) and low and middle income countries raised an important equity issue. Evidence on the temporal trends of loneliness is insufficient. The findings of this meta-analysis are limited by data scarcity and methodological heterogeneity. Loneliness should be incorporated into general health surveillance with broader geographical and age coverage, using standardised and validated measurement tools.

The risk and protective factors for suicidal burden among 251 763 school-based adolescents in 77 low- and middle-income to high-income countries: assessing global, regional and national variations

BACKGROUND

Adolescent suicide is a global public health concern and the second leading cause of adolescent death worldwide. This study aimed to estimate the burden of adolescent suicidal behaviours and its association with violence and unintentional injury, psychosocial, protective, lifestyle and food security-related factors amongst school-based adolescents across 77 countries in the six World Health Organization (WHO) regions.

METHODS

This study comprised a sample of 251 763 adolescents drawn from the latest Global School-based Student Health Survey of school-based adolescents, aged 11-17 years, across 77 countries. Logistic regression analyses were employed to estimate the adjusted effect of independent factors on adolescent suicidal behaviours.

RESULTS

The population-weighted 12-month prevalence of suicidal ideation (SI), suicidal planning (SP) and suicidal attempts (SA) amongst school-based adolescents was 18, 18 and 16%, respectively. Adolescent suicidal behaviours (i.e. SI, SP and SA) were respectively associated with being physically attacked, physical fighting, high levels of anxiety, feeling lonely, being bullied, lack of parental support, poor peer support, not having close friends and high levels of sedentary behaviours. Overall, these associations also extended to the context of food insecurity across regions and country income groups, where the magnitude of association slightly varied from odds ratios of 1.25 times to 3.13.

CONCLUSIONS

The burden of school-going adolescent suicidal thoughts, suicide planning and suicide attempts is of particular concern in low-resource countries. Comprehensive suicide prevention programmes for school-going adolescents in LMICs are needed that address socio-cultural inequities related to violence and unintentional injury, social support and psychological factors, protective, and lifestyle-related factors.

Psychosocial Correlates of Suicidal Behavior among Adolescents under Confinement Due to the COVID-19 Pandemic in Aguascalientes, Mexico: A Cross-Sectional Population Survey

Background: Suicide and suicidal behaviors were already a global public health problem, producing preventable injuries and deaths. This issue may worsen due to the COVID-19 pandemic and may differentially affect vulnerable groups in the population, including children, adolescents, and young adults. The current study evaluated the association of affective variables (depression, hopelessness, and anxiety), drug use (alcohol, tobacco, and others), emotional intelligence, and attachment with suicidal behaviors. Methods: A state-wide survey included 8033 students (51% female, 49% male; mean age of 16 years) from science and technology high-schools using a standardized questionnaire that was distributed online. Multinomial logistic regression models tested associations between suicidal behaviors and several covariates. The analyses accommodated the complex structure of the sample. Results: Approximately 21% of all students reported a suicidal behavior (11% with a low-lethality suicide attempt, 6% with self-injuries, and 4% with a high-lethality suicide attempt). Variables associated with higher odds of suicidal behavior included: female sex, depression, hopelessness, anxiety, alcohol and tobacco use, childhood trauma, and having to self-rely as issues affecting attachment, and low self-esteem. Security of attachment was associated with lower odds of suicidal behavior. Conclusions: The complexity of suicidal behavior makes it clear that comprehensive programs need to be implemented.

Patterns of adverse childhood experiences and suicidal behaviors in adolescents: A four-province study in China

BACKGROUND

Adverse childhood experiences (ACEs) are associated with increased suicidal behaviors in adolescents and most research has been restricted to certain types of or cumulative exposure to ACEs. Few studies have examined the association between patterns of ACEs and suicidal behaviors.

OBJECTIVE

To identify the contributions of type and pattern of exposure to ACEs to suicidal behaviors and their gender differences among middle school students in China.

METHODS

A school-based health survey was conducted in four provinces in China between 2017 and 2018. 14 500 students aged 10-20 years completed standard questionnaires, to record details of ACEs, suicide ideation, suicide plan, and suicide attempt.

RESULTS

Latent class analysis indicated four distinct patterns of ACEs exposure: high ACEs (6.3%), high abuse and neglect (21.4%), high neglect (45.5%), and low ACEs (26.8%). Logistic analyses showed that, compared with low ACEs, the high ACEs were more likely to report suicidal behaviors. No gender differences were found in the independent effects of ACEs type or pattern on suicidal behaviors, except for the emotional neglect associated with suicidal behaviors in girls than boys.

LIMITATIONS

The study was cross-sectional and used self-reported questionnaires. Thus, it is difficult to establish a causal relationship between patterns of ACEs and suicidal behaviors.

CONCLUSION

Our findings addressed the need for a comprehensive consideration of ACEs in preventive healthcare work to identify children exposed to the most problematic ACE patterns. The study provided the evidence of targeted intervention to preempt the emergence of suicide behavior in at-risk students in adolescents.

Single and Multiple Suicide Attempts: Prevalence and Correlates in School-Going Adolescents in Liberia in 2017

Background

This investigation aimed to estimate the prevalence and correlates of single and multiple suicide attempts among adolescents in Liberia.

Methods

Cross-sectional nationally representative data were analysed from 2744 adolescents (18 years of median age) who participated in the "2017 Liberia Global School-Based Student Health Survey (GSHS)".

Results

Results indicate that 33.7% of students had made a suicide attempt in the past 12 months (16.5% single and 17.2% multiple suicide attempts). In adjusted multinomial logistic regression analysis, having no close friends, loneliness, having been frequently physically attacked, ever used amphetamine and fast food intake were associated with multiple suicide attempts in the past 12 months. In addition, having been frequently in a physical fight and current tobacco use were associated with single suicide attempt. In sex stratified analyses, in addition, among boys frequent bullying victimization and among girls, parental tobacco use and parents never or rarely check on home work were associated with multiple suicide attempts. Multiple psychosocial distressors, multiple social-environmental factors, and multiple health risk behaviours were associated with single and multiple suicide attempts.

Conclusion

One in three students had made suicide attempt in the past 12 months (one in six students multiple suicide attempts) and several associated variables were detected which can aid in designing intervention strategies.

Effects of psychosocial and socio-environmental factors on anxiety disorder among adolescents in Bangladesh

BACKGROUND

Anxiety is a common psychiatric disorder among adolescents in developing countries. This study aimed to examine the risk factors of anxiety disorder and the adverse consequences of anxiety disorder among adolescents in Bangladesh.

METHODS

A total of 2,989 adolescent data of the 2014 Global School-based Student Health Survey (GSHS), Bangladesh, was analyzed WHO. The prevalence of anxiety disorder across psychosocial and socio-environmental factors was calculated as descriptive statistics, whereas their effects on occurring anxiety disorder were determined using the unadjusted and adjusted multivariable binary logistic regression model. The consequences of anxiety disorder were also determined using the multivariable binary logistic regression model.

RESULTS

The prevalence of anxiety disorder was 4.7%, which was found higher among female than their male counterparts. The psychosocial factors were found associated with the anxiety disorder are loneliness (AOR: 2.26, 95% CI: 1.08-4.72), being bullied (AOR: 6.00, 95% CI: 3.14-11.47), and physical abuse (AOR: 2.12, 95% CI: 1.07-4.21). Moreover, poor understandings with parents (AOR: 1.75, 95% CI: 1.02-3.01) and lack of peer support (AOR: 2.23, 95% CI: 1.18-4.23) were the socio-environmental factors that found associated with the anxiety disorder. Subgroup analysis across gender found these associations were consistent for adolescent male and female. Moreover, the likelihood increased with the increasing number of the adverse psychosocial, or socio-environmental factors.

CONCLUSIONS

Around 5% of school-going adolescents in Bangladesh reported anxiety associated with the exposure of single or multiple adverse psychosocial and socio-environmental factors including bullying and physical abuse. Early screening and interventions are essential, targeted to adolescent at risk, which could reduce the rate of anxiety disorder among adolescent in Bangladesh.

Suicidal ideation among Bangladeshi university students early during the COVID-19 pandemic: Prevalence estimates and correlates

Lockdown, social isolation, and interruption of daily life during the COVID-19 period have impacted many lives. University students are particularly vulnerable to such disruptions and may be particularly disposed to suicidal ideation, potentially creating a new public health crisis. This study aimed to assess suicidal ideation and associated factors among university students in Bangladesh during the early stages of the COVID-19 pandemic. A cross-sectional online survey was conducted using the Google form (Google survey tool) from April to May 2020. Initially, 3366 respondents voluntarily completed the survey form. Finally, 3331 surveys were included in the final analyses after removing incomplete surveys. The data ware reviewed, rechecked, and analyzed with SPSS (25.0 version) software. A total of 1979 (59.4%) males and 1352 (40.6%) females participated. Respondents were between the ages of 18 to 28 years (mean age 21.4 years [SD = 1.9]). The prevalence estimate of suicidal ideation was 12.8%. Potential risk factors included less sleep, excess sleep, cigarette smoking, past suicidal thoughts, suicide attempt history, family history of suicidality, depression, anxiety, and stress. Potential protective factors included being male, having lower SES, living in rural areas, regular physical exercise, and satisfactory study. Suicidal ideation was prevalent among Bangladeshi university students during the onset of the COVID-19 pandemic. Understanding the correlates of suicidal ideation may aid to develop targeted strategies to support students during and after the COVID-19 pandemic.

Psychosocial and socio-environmental factors associated with adolescents' tobacco and other substance use in Bangladesh

BACKGROUND

Tobacco, alcohol, and marijuana are the top three substances used by adolescents. The adverse health effects of these three substances are well documented in epidemiological literature, yet little is known about the substance use and associated factors among adolescents in Bangladesh. This study examines the risk factors for tobacco and other substances use among school-going adolescents in Bangladesh.

METHODS

We analyzed data from the 2014 Bangladesh Global School-based Student Health Survey (GSHS) of adolescents aged 13-17 years. We used two outcome measures: tobacco use (TU) and other substance use (SU; alcohol and/or marijuana). We examined a set of reported psychosocial and socio-environmental adverse events as risk factors. Logistic regression analyses were used to identify associations.

RESULTS

The prevalence of TU and other SU among school-going adolescents was 9.6% and 2.3%, respectively. The likelihood of TU and other SU was higher among adolescents who reported being bullied (TU: adjusted odd ratio [AOR]: 1.93; 95% confidence interval [CI]: 1.24-3.00; and other SU: AOR: 3.43; 95% CI: 1.46-7.99) and having sexual history (TU: AOR: 19.38; 95% CI: 12.43-30.21; and other SU: AOR: 5.34; 95% CI: 2.17-13.29). Moreover, anxiety-related sleep loss was associated with adolescents' TU (AOR: 2.41; 95% CI: 1.02-5.82) whereas the likelihood of other SU (AOR: 3.27; 95% CI: 1.14-9.44) was higher among lonely adolescents. Experience of adverse socio-environmental factors, such as parental substance use (TU: AOR: 7.81; 95% CI: 5.08-12.01), poor monitoring (TU: AOR: 1.96; 95% CI: 1.16-3.31) and poor understanding (TU: AOR: 2.22; 95% CI: 1.36-3.65), and lack of peer support (TU: AOR: 3.13; 95% CI: 1.84-5.31; and other SU: AOR: 2.45; 95% CI: 1.02-5.91), and truancy (other SU: AOR: 4.29; 95% CI: 1.81-10.12) were also positively associated with TU and/or other SU. Additionally, higher odds of tobacco use were observed among adolescents who reported 1 (AOR: 4.36 times; 95% CI: 1.34-14.24), 2 (AOR: 8.69 95% CI: 1.67-28.23), and ≥3 (AOR: 17.46; 95% CI: 6.20-49.23) adverse psychosocial experiences than who did not report any psychosocial events.

CONCLUSIONS

Tobacco and other substance use among school-going adolescents are prevalent in Bangladesh. Several psychosocial and socio-environmental events are associated with TU and other SU, which should be incorporated into adolescent substance use and health promotion programs.

Prevalence and associated factors of psychological distress among a national sample of in-school adolescents in Morocco

BACKGROUND

The goal of the study was to estimate the prevalence and correlates of psychological distress among adolescent school children in Morocco.

METHODS

Nationally representative cross-sectional data were analysed from 6745 adolescents (15 years median age) that responded to questions on a two-item measure of psychological distress from "2016 Morocco Global School-Based Student Health Survey (GSHS)."

RESULTS

The prevalence of psychological distress was 23.3, 18.0% among males and 29.2% among females. In adjusted logistic regression analysis, female sex, older age, bullying victimization, infrequently physically attacked, frequent participation in physical fights, having no close friends, frequent experience of hunger, parental emotional neglect, parental disrespect of privacy, school truancy, sedentary behaviour and having sustained a single or multiple serious injuries (past year) were associated with psychological distress. In addition, in unadjusted analysis, low peer support, parents never check homework, exposure to passive smoking, substance use (current tobacco use, current cannabis use and ever used amphetamine), frequent soft drink and frequent fast food consumption were positively and fruit and vegetable intake was negatively associated with psychological distress.

CONCLUSION

Almost one in four students reported psychological distress and several associated factors were identified which can aid prevention and control strategies.

Prevalence of Worry-Induced Sleep Disturbance and Associated Factors among a National Sample of In-School Adolescents in Lebanon

Persistent worry can cause significant distress among adolescents. The goal of this study was to estimate the prevalence and correlates of worry-induced sleep disturbance (WISD) among adolescent school children in Lebanon. Cross-sectional, nationally representative data were analysed from 5849 adolescents (15 years median age) that took part in the "2017 Lebanon Global School-Based Student Health Survey (GSHS)". The results indicate that the prevalence of WISD was 14.7%, 9.6% among males and 17.2% among females. In adjusted logistic regression analysis, loneliness, older age, female sex, having no close friends, infrequent bullying victimization, parents disrespected privacy, current tobacco use, ever cannabis use, high leisure-time sedentary behaviour and having sustained multiple serious injuries (past year) were associated with WISD. In addition, in unadjusted analysis, mostly or always feeling hungry (or low economic status), school truancy, having been physically attacked, frequently being in physical fights (past year), low peer support, parental emotional neglect, parents never checking homework, ever drunk and frequent soft drink intake were positively, and infrequent fast food intake was negatively, associated with WISD. One in seven students reported WISD and several associated factors were identified, which can aid intervention strategies. Multi-level interventions are needed targeting psychosocial distress, social-environmental factors and health risk behaviours to prevent WISD in this adolescent school population.
