The associations between health risk behaviors and suicidal ideation and attempts in an urban Chinese sample of adolescents

Associations of suicidal behaviors with body weight and body weight perception in Chinese adolescents: 2007-2022

PURPOSE

To estimate the time trend in the prevalence of suicidal behaviors including ideation and attempts in Chinese adolescents; to examine the association between suicidal behaviors and overweight (OW)/obesity (OB) and self-perceived weight status.

METHODS

Data from Youth Risk Behavior Surveys conducted in Ningbo in 2007, 2012, 2017 and 2022 were used for the study. A multistage sampling procedure was used to select respondents aged 12 to 19 years who participated in each survey. Repeated cross-sectional data of anthropometry, weight perception and suicidal behaviors were collected through self-administered questionnaires. A generalized linear model was used to assess associations of ideation and attempts, and weight status and self-perceived weight status.

RESULTS

The sample sizes for each survey wave were 937, 889, 1528 and 2655. The prevalence of ideation increased from 11.95% in 2007 to 18.15% in 2022, while the prevalence of attempts remained stable (4.48%-4.26%). An increasing trend in ideation and attempts was found in adolescents who were OW/obese and self-perceived OW/OB from 2007 to 2022. Self-perceived OW/OB adolescents had a significant increase in ideation. Girls had higher likelihood of ideation and attempts for both weight status and self- perceived weight status. While, adolescents aged 12.0-15.9 years had higher odds of ideation than those aged 16.0-19.9 years.

CONCLUSION

Adolescents' self-weight perception, rather than actual weight status, is a critical risk factor of increased likelihood of ideation and attempts in Chinese adolescents. Our findings can support to promote self-esteem growth in school-based health education programmes for prevention of suicidality and psychological health problems.

[What is the contribution of smoking to the increased risk of suicide in young smokers? A systematic review]

OBJECTIVES

The correlation between smoking and suicide is well documented in the general population: there is an increased risk of suicide among tobacco smokers. However, the association between smoking and suicidal behaviors (ideations, plans, attempts) in youth is poorly elucidated. This is a systematic review of the literature examined data on the relationship between active and passive smoking and suicidal ideation (SI), suicide planning (SP), and suicide attempts (SA) among youth in the general population.

METHOD

Medline searches were performed for the period 1980-2020. Cross-sectional, case-control, prospective population-based studies of young people (age less than 18 years) were included in this review; studies of specific populations (patients with an identified pathology of any kind) were excluded.

RESULTS

This review included 43 studies: 23 studies on the association between active smoking and SI, SI and/or PS, TS; three studies on the association between passive smoking and suicidal behavior, three studies on the association between smoking and suicidal behavior in young people in psychiatric hospital settings, and five studies comparing the suicidal behavior of girls and boys. Analysis of the data collected lead to the conclusion that active or passive smoking is associated with suicidal behavior in young people. Smoking appears to contribute to psychopathological disorders, including depression, the use of other psychoactive substances, or psychosocial suffering which are often associated with an increased risk of suicide in young people. The correlations between smoking and the presence of mental disorders have been highlighted; tobacco use may contribute to the development of depression, anxiety and stress. Further studies are needed to verify the existence of a causal link between smoking and suicide.

CONCLUSION

Smoking is associated with the risk of suicidal behavior in young people; it should be included among the criteria for assessing suicidal risk in youth. Smoking cessation, which improves psychological well-being, should be further integrated into the prevention of suicidal behavior.

The concurrence of sexual violence and physical fighting among adolescent suicide ideators and the risk of attempted suicide

Sexual violence and physical fighting are independent risk factors for suicidal behaviors among adolescents. However, whether the concurrence of these two risk factors increases the risk of suicidal behaviors among ideators, and by how much that risk increases are unknown. This study analyzed data from the 2019 National Youth Risk Behavior Surveys. Students who reported having seriously considered attempting suicide in the past year were included (n = 1755). The associations between physical fighting/sexual violence status and the risk of suicide attempt/plan/attempt requiring medical intervention were estimated. The concurrence of physical fighting and sexual violence substantially increased the relative risk of attempted suicide (adjusted relative risk, adRR = 1.99, 95% CI 1.72, 2.29) and attempted suicide requiring medical intervention (adRR = 4.07, 95% CI 2.84, 5.85; subgroup analyses: among women, adRR = 3.33, 95% CI 2.14, 5.17; among men, adRR = 6.25, 95% CI 3.32, 12.28). Among students who had experienced concurrent physical fighting and sexual violence, more suicide-attempt-associated health-risk behaviors were reported by men (median = 14) than women (median = 12) (p = 0.0023). The concurrence of physical fighting and sexual violence among adolescent suicide ideators was shown to be significantly associated with an increased risk of attempted suicide. A wide variety of health-risk behaviors were shown to cluster with the concurrence of physical fighting and sexual violence. This was especially the case among men, consistent with their higher rate of attempted suicide requiring medical intervention.

The Relations Between Identity Disturbances, Borderline Features, Internalizing Disorders, and Suicidality in Inpatient Adolescents

Previous studies have demonstrated positive associations between identity disturbances and suicidality in adolescents; however, mechanisms underlying these relationships are not well understood. The authors propose that borderline features and various internalizing disorders may mediate these relations. The aim of this study was to test a multiple mediation model of the associations between these constructs using structural equation modeling. Ninety-six inpatient adolescents aged 12-17 years completed the Assessment of Identity Development in Adolescents, the Childhood Interview for DSM-IV Borderline Personality Disorder, the Youth Self-Report, and the Columbia-Suicide Severity Rating Scale. Findings partly confirmed the theoretical model. Borderline features mediated the positive effect of identity disturbances on suicidal ideation severity. Mediations of withdrawn/depression and anxiety/depression on the effect of identity disruption on suicidal ideation intensity were demonstrated. Identity disruptions and borderline and depressive symptoms could be possible targets for interventions for youth experiencing suicidal ideation.

Influence of coping strategies on the efficacy of YAM (Youth Aware of Mental Health): a universal school-based suicide preventive program

The school-based mental health promotion and suicide prevention universal program Youth Aware of Mental Health (YAM) significantly reduces incident suicide attempts and severe suicidal ideation. This paper aims at elucidating psychological mechanisms underlying YAM's efficacy. Our hypothesis is that YAM operates through interactions with coping strategies (CS) on the reduction of suicidal ideation (SI). In the Saving and Empowering Young Lives in Europe (SEYLE) study, five coping strategies were assessed at baseline (T0) and 12-month follow-up (T12): "learning", "help-seeking", "arts", "sports" and "fight". We analyzed interactions between the YAM intervention, coping strategies and SI in the YAM group (N = 1693) and the minimal intervention group (N = 1909), after excluding prevalent cases with SI and previous suicide attempts from our total sample (N = 5654). General Linear Mixed Model regressions were performed. The present study confirms that coping strategies play an influential role on suicidal ideation. Our results showed that YAM acts whatever the prevailing coping strategies used. It is particularly efficient for pupils insufficiently using adaptive coping strategies such as LEARN and HELP-SEEKING or using maladaptive coping strategies, such as ARTS and FIGHT. The socialization induced by the YAM intervention seems to be a strong component of its efficiency.

Risk factors associated with suicidal ideation and suicide attempts in Bhutan: An analysis of the 2014 Bhutan STEPS Survey data

Suicide is a major public health problem globally. Data on the factors influencing suicidal behaviours that can inform prevention policies are limited in Bhutan. This study used the dataset of the nationally-representative Bhutan STEPS Survey conducted in 2014 that assessed the non-communicable disease risk factors. Using a backward elimination approach, multiple logistic regression analysis accounting for the complex survey design was performed to identify the factors associated with suicidal ideation and suicide attempts in adults separately. The prevalence of suicidal ideation and suicide attempt was 3.1% and 0.7%, respectively. We found female gender, being unemployed, low and middle household income than high household income, and having a family history of suicide were associated with higher odds of having suicidal ideation. Younger age and alcohol consumption were associated with both suicidal ideation and suicide attempts. While those from the middle-income group compared to those in the high-income group had reduced odds of attempting suicide. The findings can help inform policy investments for suicide prevention. Prevention programs that target young people, females, and low socioeconomic groups, and aimed to reduce harmful alcohol use can help prevent suicidal behaviours.

A latent class analysis of health lifestyles and suicidal behaviors among US adolescents

BACKGROUND

Previous studies have documented the link between individual health behaviors and suicide, but little is known about the influence of health lifestyles on suicide among adolescents. This study aims to identify the unobserved patterns of health behaviors and to examine their associations with adolescent suicidal behaviors to inform screening of suicidality.

METHODS

Data were derived from a nationally representative sample of adolescents (n = 14,506, ages 12-18, 50.9% female) in the national school-based 2017 Youth Risk Behavior Survey. Latent class analysis was performed based on 13 health behaviors related to diet (e.g., frequency of consuming breakfast, fruits/vegetables, soda), physical activity (frequencies of physical activity, sports team participation), sleep, and media use (TV/computers). Suicidal behaviors were measured by three dichotomized variables, including suicidal ideation, plan, and attempts. Multivariate logistic regressions were used to examine associations between identified classes and suicidal behaviors.

RESULTS

Four classes of health lifestyles were identified. Class 1 (23.6%) consistently engaged in health-promoting behaviors, including eating breakfast daily, high intake of fruits/vegetables, physically active, and infrequent use of TV/computers. Class 2 (37.7%) had an irregular diet, moderate exercise, and high computer use. Class 3 (31.8%) had moderate diet, frequent exercise, and moderate sleep. Class 4 (6.9%) had the lowest engagement in health-promoting behaviors. Class 4 had higher odds of suicide plan than Class 1 (OR = 1.50, 95% CI = 1.10-2.05). Notably, Class 2 and 3 were less likely to attempt suicide than Class 1 (OR = 0.74, 95% CI = 0.57-0.95 for Class 2; OR = 0.65, 95% CI = 0.48-0.89 for Class 3).

LIMITATIONS

Due to the cross-sectional design, no causal inference can be drawn.

CONCLUSIONS

Both Class 1 (consistent) and Class 4 (lowest) engagement in health-promoting behaviors were associated with increased suicidal behaviors. Suicide prevention efforts that examine both lifestyles are keys to early detection of suicidal ideation and plans, and prevention of suicide attempts.

Association between body weight status and suicidal ideation among Chinese adolescents: the moderating role of the child's sex

PURPOSE

Suicidality (ranging from suicidal ideation to suicidal attempts and completed suicide) is a major and preventable public health concern, and body weight is considered a modifiable factor which might be helpful to the early risk assessment of suicidal ideation. This study aimed to comprehensively evaluate the association of body weight status with suicidal ideation across sex among Chinese adolescents.

METHODS

Data were drawn from the 2015 National School-based Chinese Adolescents Health Survey, and 54,640 students' questionnaires were completed and qualified for the survey. Body mass index z scores were calculated and categorized into four levels: underweight (less than the 5th percentile for sex and age), normal weight (between the 5th and 85th percentile), overweight (between the 85th and 95th percentile), and obese (above the 95th percentile).

RESULTS

Of the total sample, 47.3% (25,852) were boys. The weighted prevalence of suicidal ideation among Chinese adolescents is 15.7% (14.6% in boys and 17.3% in girls). After adjusting for demographics, smoking, drinking, and depressive symptoms, our final multivariate logistic regression models demonstrated that only boys identified as underweight (Adjusted odds ratio [AOR] = 1.23, 95% CI = 1.06-1.44) or obese (AOR = 1.19, 95% CI = 1.02-1.38) were at a higher risk of suicidal ideation. Additionally, the association between weight status and suicidal ideation among boys might be moderated by academic pressure, smoking, and depressive symptoms.

CONCLUSIONS

There was a significant J-shaped association between relative body weight and suicidal ideation in boys. The child's sex should be taken into consideration when developing interventions against unhealthy weight and suicidal ideation.

Factors associated with suicidal ideation and suicidal attempts among adolescent students in Nepal: Findings from Global School-based Students Health Survey

INTRODUCTION

Suicide has been recognized as a major public health problem with high burden in low and middle income countries. Suicide has long lasting psychological trauma on friends and relatives in addition to loss of economic productivity. Although the need of high quality evidence is essential for designing suicide prevention program, Nepal lacks reliable evidence from nationally representative data. This study aimed to estimate the prevalence of suicidal ideation and attempt among adolescent students and identify the factors associated with them.

MATERIALS AND METHODS

Total of 6,531 students of grade 7 to 11 from 74 schools representing all three ecological belts and five development regions participated in this cross sectional study. To select the representative sample from study population, two stage cluster sampling method was used. Standardized self-administered questionnaire were completed by participants. Multivariable logistic regression was done to identify the factors associated with suicidal ideation and attempt.

RESULTS

Nearly 13.59% of the participants had considered suicide while 10.33% had attempted it. Food insecurity (OR = 2.32, CI = 1.62-3.32), anxiety (OR = 2.54, CI = 1.49-4.30), loneliness (OR = 2.51, CI = 1.44-4.36) and gender (OR = 1.39, CI = 1.03-1.89) were identified as risk factors of suicidal ideation. Anxiety (OR = 3.02, CI = 1.18-7.74), loneliness (OR = 2.19, CI = 1.28-3.73) truancy (OR = 1.99, CI = 1.40-2.82), cigarette use (OR = 3.13, CI = 1.36-7.23) and gender (OR = 1.60, CI = 1.07-2.39) were identified as risk factors of suicidal attempt. Having 3 or more close friends was found to have protective effect (OR = 0.35, CI = 0.16-0.75) against suicidal attempt.

CONCLUSION

Study reveals relatively high prevalence of suicidal ideation and suicidal attempt among school-going adolescents in Nepal. Appropriate coping strategies for factors like anxiety, loneliness seem could be useful for preventing both suicidal ideation and attempt.

Association between sexual behavior and suicidal ideation among South Korean middle school students

AIM

To identify the association between sexual behavior and suicidal ideation among South Korean middle school students.

METHODS

This study used raw data from the 2013 Korean Youth Risk Behavior Web-Based Survey. Among the data from 72,435 students, the data from 36,530 individuals in middle school were analyzed. The prevalence of sexual behavior and suicidal ideation, according to the participants' general characteristics, and suicidal ideation, according to sexual behaviors, were assessed by using a complex sample Chi-squared test. A complex sample logistic regression was used to examine the association between sexual behavior and suicidal ideation.

RESULTS

Overall, 3.8% of the students reported having had sexual intercourse and 17.6% of the students reported suicidal ideation during the past 12 months. Having had sexual intercourse was statistically significantly associated with suicidal ideation. The students who had had sexual intercourse usually used contraception and those who had contracted sexually transmitted diseases were more likely to report suicidal ideation in both the unadjusted and adjusted models.

CONCLUSION

This study illustrates the need to develop a prevention program that addresses the common factors between sexual behavior and suicidal ideation in order to effectively reduce both sexual behavior and suicidal ideation in middle school students.

Prevalence and Correlates of Suicidal Behaviors among College Students in Northeastern China: a Cross-Sectional Study

The present study aimed to investigate the prevalence and correlates of suicidal behaviors among college students in Jilin Province, China. A cross-sectional survey was conducted in 2016, using a self-reported questionnaire. Convenience sampling method was used to select college students as participants. The analysis was based on a sample of 730 college students. We use multivariate logistic model to determine the risk factors of suicidal behaviors.The prevalence of suicidal ideation, suicidal plan, suicidal attempts were respectively 13.2%, 3.3% and 3.4%. After controlling for the potential confounding factors, history of family psychiatric illness, depression and quality of life were significantly associated with suicidal ideation. Besides, suicidal plan was predicted significantly by not living together with university roommates and depression. In terms of suicidal attempts, not living together with university roommates and history of family psychiatric illness were its risk factors. Comprehensive interventions regarding aims at risk factors may be critical as effective strategies to protect college students from suicide.

Suicidal ideation and associated factors among students aged 13-15 years in Association of Southeast Asian Nations (ASEAN) member states, 2007-2013

OBJECTIVE

The aim of this study was to assess suicidal ideation and associated factors in school-going adolescents in the Association of Southeast Asian Nations (ASEAN) member states.

METHODS

The analysis included 30,284 school children aged 13-15 years from seven ASEAN countries that participated in the cross-sectional global school-based student health survey (GSHS) between 2007 and 2013.

RESULTS

The overall prevalence of suicidal ideation in the past 12 months across seven ASEAN countries was 12.3%, significantly higher in girls (15.1%) than boys (9.3%). Among seven ASEAN countries with the highest prevalence of suicidal ideation was in the Philippines (17.0%) and Vietnam (16.9%) and the lowest in Myanmar (1.1%) and Indonesia (4.2%). In multivariable logistic regression analysis, female gender, older age (14 or 15 years), living in a lower middle income country, having no friends, loneliness, bullying victimisation, having been in a physical fight in the past 12 months, lack of parental or guardian support, tobacco use and having a history of ever got drunk were associated with suicidal ideation.

CONCLUSIONS

Different rates of suicidal ideation were observed in ASEAN member states. Several risk factors for suicidal ideation were identified which can help guide preventive efforts.

The mediating effects of depressive symptoms and sleep quality on the relationship between the non-medical use of prescription drugs and suicidal behaviors among Chinese adolescents

BACKGROUND

The nature of the relationship between the non-medical use of prescription drugs (NMUPD) and suicide has not been clearly elucidated. Some studies have suggested that the relationship between substance use and suicidal ideation may be spurious and could be explained by other variables.

METHODS

A school-based cross-sectional study was performed in Guangzhou. A total of 5853 students completed questionnaires and were included in the study. NMUPD, alcohol use, illicit drug use, depressive symptoms, sleep quality, and suicidal behaviors were assessed. The mediating effects of depressive symptoms and sleep quality on the relationship between NMUPD and suicidal behaviors were examined using a structural equation model.

RESULTS

In the simple model without mediation, a positive relationship between NMUPD and suicidal behaviors in adolescents was found, which was independent of effects from the use of other substances. Both depressive symptoms and sleep quality were significant mediators of this relationship.

CONCLUSION

Public health and educational professionals should survey depressive symptoms and sleep quality and provide interventions when managing suicidal behaviors among adolescents engaging in NMUPD.

Prevalence and correlates of suicidal ideation and attempts among children and adolescents

Suicide is a potentially preventable public health issue. It is therefore important to examine its immediate precursors, including suicidal ideation and attempts, to help in the development of future public health interventions. The present study reports the prevalence of suicidal ideation and attempts in the past 12 months in children and adolescents and identifies correlates of such behaviors in a large and diverse sample of middle and high school students. Data were drawn from a representative sample of Ottawa students (n=1922) aged 11-20 years (14.4±1.9 years) from three cycles (2009, 2011 and 2013) of the Ontario Student Drug Use and Health Survey (OSDUHS), a cross-sectional school-based appraisal of students in grades 7-12 across Ontario, Canada. Overall, 10.8% of students exhibited suicidal ideation and 3.0% reported suicide attempts in the past 12 months. The conditional probability of making an attempt was 25.5% among suicide ideators. Multivariable analyses indicated that being a girl and using alcohol and cannabis were positively associated with suicidal ideation, while tobacco was positively associated with suicide attempts. Being a victim of school bullying was significantly associated with reports of suicidal ideation and attempts, whereas school connectedness had protective effects against both suicidal ideation and attempts. These results indicate that suicidal ideation and attempts are related to other risky behaviors. Suicide-prevention efforts should be integrated within broader health-promoting initiatives.

Association of Overweight with the Prevalence of Lifetime Psychiatric Disorders and Suicidality: General Population-based Study in Korea

Many epidemiological studies suggest that overweight is associated with an elevated risk of psychiatric disorders and suicidal tendency. However, findings vary across studies, and some have contradictory results. We investigated the relationship of overweight with a range of psychiatric disorders and suicidality in the Korean general population. A multistage cluster sampling design was adopted. A total of 6,022 participants aged 18-74 years completed face-to-face interviews (response rate: 78.7%) including assessment of psychiatric disorders, suicidality, and height and weight. Overweight (defined as body mass index of ≥ 25) was associated with an increase in the lifetime prevalence of depressive disorders (adjusted odds ratio [AOR] 1.38; 95% confidence interval [CI], 1.07-1.77), suicidal ideation (AOR, 1.42; 95% CI, 1.20-1.68), and suicidal plans (AOR, 1.44; 95% CI, 1.02-2.03), controlling for sociodemographic variables. Subgroup analysis found that the association between overweight and depressive disorders exists only in women aged 18-44 years (AOR, 1.75; 95% CI, 1.07-2.89) while the association of overweight with suicidal ideation (AOR, 2.08; 95% CI, 1.53-2.82) and suicide plans (AOR, 2.59; 95% CI, 1.25-5.37) existed only in men aged 18-44 years. Overweight was associated with increased odds of nicotine use disorders in women aged 18-44 years (AOR, 2.35; 95% CI, 1.02-5.43), but the association was in the opposite direction in men aged 45-74 years (AOR, 0.64; 95% CI, 0.43-0.94). In conclusion, overweight is related to various psychiatric disorders and suicidality in Korea. Policy makers and clinicians should pay more attention to the mental health of overweight individuals.

Effort-reward Imbalance at Work, Parental Support, and Suicidal Ideation in Adolescents: A Cross-sectional Study from Chinese Dual-earner Families

BACKGROUND

In contemporary China, most parents are dual-earner couples and there is only one child in the family. We aimed to examine the associations of parents' work stress with suicidal ideation among the corresponding adolescent. We further hypothesized that low parental support experienced by adolescents may mediate the associations.

METHODS

Cross-sectional data from school students and their working parents were used, with 907 families from Kunming City, China. Stress at work was measured by the effort-reward imbalance questionnaire. Perceived parental support was assessed by an item on parental empathy and their willingness to communicate with the adolescent. Suicidal ideation was considered positive if students reported thoughts about suicide every month or more frequently during the previous 6 months. Logistic regression was used to examine the associations.

RESULTS

We observed that parents' work stress was positively associated with low parental support, which was in turn associated with adolescent suicidal ideation. The odds ratio for parents' work stress and adolescent suicidal ideation was 2.91 (95% confidence interval: 1.53-5.53), and this association was markedly attenuated to 2.24 (95% confidence interval: 1.15-4.36) after additional adjustment for parental support. Notably, mothers' work stress levels exerted stronger effects on children's suicidal ideation than those of fathers.

CONCLUSION

Parents' work stress (particularly mother's work stress) was strongly associated with adolescent's suicidal ideation, and the association was partially mediated by low parental support. These results need to be replicated and extended in prospective investigations within and beyond China, in order to explore potential causal pathways as a basis of preventive action.

Prevalence and risk factors associated with suicidal ideation among adolescents in Malaysia

BACKGROUND

Suicidal ideation, defined as thoughts, ideas and the desire to commit suicide, is becoming a major public health problem among adolescents. Indeed, suicidal ideation is known as a key predictor of future suicide risk.

OBJECTIVE

This study aims to determine the prevalence and risk factors associated with suicidal ideation among adolescents in Malaysia.

METHODS

This study used data from the 2013 Malaysian adolescent health risk behavior (MyAHRB) study, a cross-sectional school survey conducted in Peninsular Malaysia among school-going adolescents aged 16-17 years (n=2789). Logistic regression analysis was used to determine the risk factors associated with suicidal ideation among Malaysian adolescents.

RESULTS

The overall prevalence of suicidal ideation among the adolescents was 6.2%. The prevalence was significantly higher among females than males (7.6% vs. 4.7%; p=0.002). Multivariate regression analysis revealed that adolescents who were females [odds ratio (OR)=2.02; 95% confidence interval (CI): 1.40-2.92] or of Indian ethnicity (OR=2.32; 95% CI: 1.35-3.98) were more likely to report suicidal ideation. Loneliness (OR=2.54; 95% CI: 1.57-4.11), anxiety or worry (OR=2.70; 95% CI: 1.70-4.31), no close friends (OR=2.71; 95% CI: 1.43-5.14), and lack of supportive peers (OR=1.69; 95% CI: 1.15-2.47) were identified as risk factors for adolescents' suicidal ideation. Adolescents who ever had sexual intercourse (OR=2.70; 95% CI: 1.48-4.92) and had been in a physical fight (OR=2.45; 95% CI: 1.62-3.70) were also reported to have higher risks of suicidal ideation.

CONCLUSION

This study provides evidence on risk factors associated with suicidal ideation among Malaysian adolescents. Targeted mental health and health risk behavioral interventions for high-risk adolescents are recommended.

Smoking and Suicide: A Meta-Analysis

BACKGROUND

Many studies have reported a positive association between smoking and suicide, but the results are inconsistent. This meta-analysis was carried out to estimate the association between smoking and suicidal ideation, suicide plan, suicide attempt, and suicide death.

METHODS

Major electronic databases including PubMed, Web of Science, Scopus, and ScienceDirect were searched until May 2015. The reference lists of included studies were screened too. Epidemiological studies addressing the association between smoking and suicidal behaviors were enrolled. The heterogeneity across studies was explored by Q-test and I2 statistic. The possibility of publication bias was assessed using Begg's and Egger's tests and Trim & Fill analysis. The results were reported based on risk ratio (RR) and odds ratio (OR) with 95% confidence intervals (CI) using a random-effects model.

RESULTS

We identified a total of 8062 references and included 63 studies with 8,063,634 participants. Compared to nonsmokers, the current smokers were at higher risk of suicidal ideation (OR = 2.05; 95% CI: 1.53, 2.58; 8 studies; I2 = 80.8%; P<0.001), suicide plan (OR = 2.36; 95% CI: 1.69, 3.02; 6 studies; I2 = 85.2%; P<0.001), suicide attempt (OR = 2.84; 95% CI: 1.49, 4.19; 5 studies; I2 = 89.6%; (P<0.001), and suicide death (RR = 1.83; 95% CI: 1.64, 2.02; 14 studies; I2 = 49.7%; P = 0.018).

CONCLUSIONS

There is sufficient evidence that smoking is associated with an increased risk of suicidal behaviors. Therefore, smoking is a contributing factor for suicide. Although this association does not imply causation, however, smoking prevention and cessation should be the target of suicide prevention programs.

Four Distinct Subgroups of Self-Injurious Behavior among Chinese Adolescents: Findings from a Latent Class Analysis

Self-injurious behavior (SIB) among adolescents is an important public health issue worldwide. It is still uncertain whether homogeneous subgroups of SIB can be identified and whether constellations of SIBs can co-occur due to the high heterogeneity of these behaviors. In this study, a cross-sectional study was conducted on a large school-based sample and latent class analysis was performed (n = 10,069, mean age = 15 years) to identify SIB classes based on 11 indicators falling under direct SIB (DSIB), indirect SIB (ISIB), and suicide attempts (SAs). Social and psychological characteristics of each subgroup were examined after controlling for age and gender. Results showed that a four-class model best fit the data and each class had a distinct pattern of co-occurrence of SIBs and external measures. Class 4 (the baseline/normative group, 65.3%) had a low probability of SIB. Class 3 (severe SIB group, 3.9%) had a high probability of SIB and the poorest social and psychological status. Class 1 (DSIB+SA group, 14.2%) had similar scores for external variables compared to class 3, and included a majority of girls [odds ratio (OR) = 1.94]. Class 2 (ISIB group, 16.6%) displayed moderate endorsement of ISIB items, and had a majority of boys and older adolescents (OR = 1.51). These findings suggest that SIB is a heterogeneous entity, but it may be best explained by four homogenous subgroups that display quantitative and qualitative differences. Findings in this study will improve our understanding on SIB and may facilitate the prevention and treatment of SIB.

Social and individual risk factors for suicide ideation among Chinese children and adolescents: A multilevel analysis

The objective of this study was to investigate the prevalence and predictors of suicide ideation among primary, middle and high school students. We used multilevel modelling to investigate suicide ideation among 12,733 Chinese children and adolescents aged 9-18 years from wide range of areas across China. Approximately, 32.09% of children and adolescents reported suicide ideation, with females were more likely to report suicide ideation than males (38.09% vs. 29.95%). Our results showed that the risk factors in primary school students were different from middle and high school student groups, whereas significant risk factors for middle and high school students were similar. The city's standard of living as indicated by the Engel coefficient and the city's divorce rate were positively associated with the prevalence of suicide ideation; in contrast, the school's pupil-to-teacher ratio was negatively correlated with elevated suicide ideation. Significant risk factors for suicide ideation included study anxiety, self-accusation tendency, impulsive tendency, terror tendency and physical symptoms. These results have important implications for the prevention of suicide, suggesting that both contextual (city-level) and compositional (individual-level) factors could be important targets for prevention and intervention for children and adolescents at risk of suicide ideation.

Suicidal behaviors among Moroccan school students: prevalence and association with socio-demographic characteristics and psychoactive substances use: a cross-sectional study

BACKGROUND

Suicidal behavior is a major cause of injury and death worldwide, especially among adolescents and young adults. Few studies have tackled this issue in the Arab world. The present study investigated the prevalence and the risk factors of suicidal behaviors among Moroccan school students.

METHODS

From April 2012 to November 2013, a cross-sectional study was conducted in the North-Centre region of Morocco among students in public secondary schools selected using stratified cluster random sampling. The data were collected via anonymous self-administered questionnaires. The Mini International Neuropsychiatric Interview was used in its Moroccan Colloquial Arabic version to assess suicidality according to the DSM-IV criteria.

RESULTS

A total of 3020 students (53 % boys) aged 11-23 years (average age = 16 ± 2.1 years) were included in the study. The prevalence of suicide ideation, suicide planning and suicide attempts during the last month were 15.7, 6.3, and 6.5 % respectively. Univariate analyses demonstrated that suicidal behaviors followed different epidemiological patterns. According to the multivariate analyses, the risk factors for all suicidal behaviors among Moroccan school students were the female gender, middle school level, urban locations, low family income, parents' divorce, tobacco consumption and psychoactive substances (alcohol and cannabis) use.

CONCLUSIONS

The intervention of preventive programs has become an emergency to overcome the issue of suicidality in Morocco. Further researches on adolescents' suicidal behaviors are suggested to update temporal data and assess the effectiveness of potential interventions.

Prevalence and influence factors of suicidal ideation among females and males in Northwestern urban China: a population-based epidemiological study

Background

Suicide is an urgent public health challenge for China. This study aims to examine the prevalence, influence factors, and gender differences of suicidal ideation among general population in Northwestern Urban China.

Methods

Data used in this study were derived from the third wave of a cohort study of a randomized community sample with 4291 participants (≥20 years) in 2008 in Lanzhou City and Baiyin City, Gansu Province. Data were collected via face-to-face interview by the trained interviewers. Descriptive analyses, chi-square tests and multivariate logistic regressions were performed by using Stata 12.0, as needed.

Results

The prevalence of 12-month suicidal ideation was 4.29 %, there was no significant difference between males and females [5.04 % vs 3.62 %, Adjusted Odds Ratio (AOR) = 0.83, p = 0.351]. Several risk factors for suicidal ideation were confirmed, including being unmarried (AOR = 1.55, p = 0.030), having depression symptoms (AOR = 2.33, p < 0.001), having other insurance (AOR = 1.83, p = 0.01) or no insurance (AOR = 1.73, p = 0.024). In addition, several influence factors were significantly different in males and females, such as being currently married (unmarried vs married, AOR = 1.84, p = 0.027, for females; no difference for males), feeling hopeless (hopless vs hopeful, AOR = 1.92, p = 0.06, for females; no difference for males), having other insurances (having other insurances vs having basic employee medical insurance, AOR = 1.92, p = 0.044, for males; no difference for females), having debts (having debts vs no debts, AOR = 2.69, p = 0.001, for males; no difference for females), currently smoking (smoking vs nonsmoking, AOR = 3.01, p = 0.019 for females, no difference for males), and currently drinking (drinking vs nondrinking, AOR = 2.01, p = 0.022, for males; no difference for females).

Discussion and conclusion

These findings suggested that comprehensive suicide prevention strategies should be developed or strengthened in order to prevent suicide ideation in China, and the gender-specific differences need to be explored through further researches.

Prevalence of suicide attempts among Chinese adolescents: A meta-analysis of cross-sectional studies

OBJECTIVE

According to World Health Organization, for every committed suicide there were 20 suicide attempts at least. In the last decade, despite the increasing awareness on suicide attempts among adolescents in China, there has been no comprehensive system reporting vital statistics. Consequently, the prevalence of suicide attempts reported in some studies ranged variedly. Therefore, the purpose of this study was to provide the first meta-analysis of cross-sectional studies of suicide attempts to fill this gap.

METHODS

Two reviewers independently screened potentially relevant cross-sectional studies of suicide attempts through PubMed-Medline, Embase, Wanfang Data, Chongqing VIP and Chinese National Knowledge Infrastructure databases using the core terms 'suicid*'/'suicide attempt*'/'attempted suicide' and 'adolescen*'/'youth'/'child*'/'student*' and 'China'/'Chinese' in the article titles, abstracts and keywords. Chi-square based Q test and I(2) statistic assessed the heterogeneity. Forest plot was used to display results graphically. Potential publication bias was assessed by the funnel plot, Begg's and Egger's test.

RESULTS

In total, 43 studies with 200,124 participants met the eligibility criteria. The pooled prevalence of suicide attempts among Chinese adolescents was 2.94% (95% CI: 2.53%-3.41%). Substantial heterogeneity in prevalence estimates was revealed. Subgroup analyses showed that the prevalence for males was 2.50% (95% CI: 2.08%-3.01%), and for females was 3.17% (95% CI: 2.56%-3.91%).

CONCLUSIONS

In sum, abstracting across the literatures, the prevalence of suicide attempts among Chinese adolescents was moderate compared with other countries around the world. Necessary measures should be set out prevent them in the future.

Psychosocial correlates of suicidal ideation in rural South African adolescents

Suicide is a prevalent problem among young people in Southern Africa, but prevention programs are largely absent. This survey aimed to identify the behavioral and psychosocial correlates of suicidal ideation among adolescents in Limpopo. A two-stage cluster sample design was used to establish a representative sample of 591 adolescents. Bivariate correlations and multiple linear regression analyses were conducted. Findings show that suicidal ideation is prevalent among adolescents. The psychosocial factors perceived social support and negative feelings about the family and the behavioral factors forced sexual intercourse and physical violence by the partner were found to increase the risk of suicidal ideation. Depression mediated the relationship between these psychosocial and behavioral risk factors and suicidal ideation. This study increased our understanding of the psychosocial and behavioral predictors of adolescent suicidal ideation. The findings provide target points for future intervention programs and call for supportive structures to assist adolescents with suicidal ideation.

Health-Related Factors and Suicidal Ideation in High School Students in Rural China

The study aimed to understand the reporting rate of suicidal ideation and its health-related factors in 1,378 high school students in rural China. These students were recruited from two high schools in Lijin County, Shandong Province, China by using a stratified random cluster sampling method. Overall, 13.5% of the sample reported having suicidal ideation in the past year, and there was no significant difference between boys and girls in reporting rate of suicidal ideation. Nightmares, physical activity, and sleep duration as well as family environment, paternal education, and mental heath status were significantly associated with suicidal ideation. More efforts for these factors should be considered in suicide prevention for high school students in rural China.

Drunkenness and its association with health risk behaviors among adolescents and young adults in three Asian cities: Hanoi, Shanghai, Taipei

PURPOSE

To assess the prevalence of drunkenness among adolescents in Hanoi, Shanghai, and Taipei and explore the association between heavy drinking and other health risk behaviors.

METHODS

The data are drawn from the Three-city Collaborative Study of Adolescent Health, conducted in Hanoi, Shanghai, and Taipei in 2006. A sample of 17,016 adolescents and young adults, aged 15-24 years, was selected by multistage sampling. Descriptive analysis was used to estimate the proportion of drunkenness and other health risk behaviors. Multivariate logistic regression was used to investigate relationships between drunkenness and risky health behaviors.

RESULTS

The proportions of the sample getting drunk during the past month were 6.36%, 4.53%, and 8.47% in Hanoi, Shanghai, and Taipei, respectively. More males than females reported drunkenness in all three cities, with the difference highest in Hanoi (11.08% vs. 1.14%) and lowest in Taipei (9.69% vs. 7.18%). Different levels of relationship between drunkenness and health risk behaviors, such as anxiety, suicidal ideation, smoking, gambling, fighting, drinking and driving, and having sexual intercourse, were found across the three cities; an exception was nonuse of contraception.

CONCLUSION

Drunkenness was positively associated with many health risk behaviors. It may serve as an indicator of other risky behaviors. Interventions to reduce drinking and drunkenness may contribute considerably to the prevention of other risk behaviors and to adolescent safety and well-being.

Correlation between family environment and suicidal ideation in university students in China

Background: This study investigated the association between suicidal ideation and family environment. The sample included 5183 Chinese university students. A number of studies on suicidal ideation have focused on individuals rather than families. This paper reviews the general principles of suicidal ideation and the consequences resulting from the family environment. Methods: This study used six different colleges as the dataset, which included 2645 males and 2538 females. Students were questioned with respect to social demographics and suicidal ideation factors. The data were analyzed with factor and logistic analyses to determine the association between suicidal ideation and poor family environment. Results: The prevalence of suicidal ideation was 9.2% (476/5183). Most participants with suicidal ideation had significant similarities: they had poor family structures and relationships, their parents had unstable work, and their parents used improper parenting styles. Female students were more likely to have suicidal thoughts than male students. Conclusions: This study shows that suicidal ideation is a public health issue among Chinese university students and demonstrates the importance of considering the family environment when examining university students’ suicidal ideation. Understanding family-related suicidal ideation risk factors can help to predict and prevent suicides among university students.

Stressful psychosocial school environment and suicidal ideation in Chinese adolescents

PURPOSE

Suicide is one of the leading causes of death during adolescence worldwide. This study, using a sample of Chinese adolescents, examines associations of a stressful psychosocial school environment with suicidal ideation, which were rarely investigated so far.

METHODS

A total of 1,004 Chinese students (468 boys and 536 girls) from Grade 7-12 were recruited into our questionnaire survey. Psychosocial school environment was measured by the effort-reward imbalance questionnaire adapted to the school setting, and suicidal ideation was assessed by a standardized question. Multivariate logistic regression was applied, adjusting odds ratios for age, gender, grade, smoking, alcohol drinking, physical activity, family wealth, and self-rated health.

RESULTS

In school settings, 10.86% students reported suicidal ideation during the last 6 months, which was found to be significantly related to both effort and reward. Remarkably, effort-reward imbalance was associated with elevated risk of suicidal ideation (odds ratio = 1.77, 95% confidence interval = 1.34-2.35).

CONCLUSIONS

This study finds significant associations between a stressful psychosocial school environment in terms of effort-reward imbalance and suicidal ideation in Chinese adolescents. Preventive actions aiming at reducing this imbalance may define a promising approach towards a healthy psychosocial school environment.

Influence of stressors and possible pathways of onset of seventh graders' suicidal ideation in urban and rural areas in Taiwan

BACKGROUND

Suicide is the second leading cause of death among young people in Taiwan. However, few studies have investigated children's suicidal ideation, and longitudinal studies are particularly rare. The purposes of this study were: (1) to describe the proportion of students with suicidal ideation in one month and incidence of suicidal ideation in the 7th graders (the first year of junior high school) living in urban and rural areas; (2) to realize the influence of perceived stressors on the onset of 7th graders' suicidal ideation; and (3) to explore possible pathways through which trigger factors and perceived stressors lead to suicidal ideation.

METHODS

A total of 1,589 students were followed from grade 4 to grade 7. Logistic regression was then used to investigate the influence of perceived stressors on the onset of suicidal ideation in grade 7. Structural equation modeling was used to analyze possible pathways through which trigger factors led to increased pressure from certain stressors which in turn resulted in suicidal ideation.

RESULTS

The proportion of students with suicidal ideation in one month was 2 to 3 times higher in both areas compared to that in elementary school. However, the incidence in the rural area showed a large increase from 10.2% and 9.5% in grades 5 and 6 to 15.5% in grade 7. Urban-rural difference was observed. Important stressors and pathways of suicidal ideation differ between urban and rural areas.

CONCLUSIONS

This study showed that the influential stressors in urban and rural areas might be different. Thus, interventions focused on coping skills for regional specific stressors and trigger factors could be beneficial in the transition time.

Gender-specific factors of suicide ideation among adolescents in the Republic of Korea: a nationally representative population-based study

The purposes of this study are to explore the differences in the rates of suicide ideation (SI) between male and female youths, and to investigate gender-specific factors strongly associated with SI. This study analyzed nationally representative secondary data, the Fourth Korea National Health and Nutrition Examination Survey collected over a 3 year period (2007-2009) (N=2358; youths aged 12-18 years). Significant differences in characteristics between adolescents with and without SI were analyzed using either t-test or chi-square test. After adjusting for demographics (i.e., age, monthly household income, and family intactness), gender-specific factors associated with SI were examined using multivariate logistic regression. Current research reveals that (a) the prevalence of SI is higher among female adolescents than among their male counterparts, (b) depression and stress are strong factors in both males and females, and (c) psychological counseling and experimentation with smoking and drinking are strong factors among females only. Different factors influencing SI between males and females should be considered when identifying youths at risk for SI and providing targeted interventions.

Predictors of suicidal ideation in late childhood and adolescence: a 5-year follow-up of two nationally representative cohorts in the Republic of Korea

This study explores the trajectory of suicidal ideation in childhood and adolescence and identifies its strong predictors. Secondary data obtained from two nationally representative cohorts of South Korean youth were longitudinally analyzed using frequencies, percentages, and discrete time survival analysis. This study revealed an increase in the occurrence of suicidal ideation in adolescence, a higher prevalence of suicidal ideation among females than among males, and differences in predictors of suicide ideation by developmental stages and gender. The results suggest that multifaceted factors specific to developmental stages and gender should be simultaneously considered to diminish the occurrences of suicidal ideation.

Factors associated with suicidal behaviors in mainland China: a meta-analysis

Background

Suicide is a major public health issue in China. Studies of suicide risk factors have reported both inconsistent and inconclusive results. This review aimed to determine suicide risk factors in China.

Methods

Medline/PubMed, EMBASE, CNKI (China National Knowledge Infrastructure) and VIP (Chinese Journal of Science and Technology of VIP) were searched for relevant reports. Two investigators independently assessed the eligibility of identified studies and extracted data. Pooled odds ratios (and 95% confidence intervals) were calculated for each factor with Revman 5.0.

Results

Forty-four studies with 192,362 subjects were included. The pooled results indicated that mood disorders and stressful life events (physical illness, suicide of relatives) increased the risk of suicide ideation among the entire population. Socio-family environment (single or remarried parent, study pressure and academic achievement) and unhealthy behaviors (smoking, alcohol drinking, and drug use) were risk factors for suicide ideation among youth. Unhealthy behaviors (smoking and alcohol drinking), mood disorders, and stressful life events (suicide of relatives) were the main risk factors for attempted suicide. Persons living in rural areas, and those with lower education, mood disorders, and/or a history of negative life events had a higher risk of completed suicide. In China, before 2000, females had a significantly higher rate of completed suicide than males, while after 2000, no significant gender difference was found.

Conclusions

Socio-family environment, lifestyle, life events and psychiatric/psychological factors are associated with suicidal behaviors in China. Further case–control or cohort studies are needed to better understand suicide behaviors in China. Meanwhile, there is an urgent need for comprehensive studies of suicide interventions among high-risk populations.

Suicidal ideation and associated factors among school-going adolescents in Thailand

The aim of this study was to estimate the prevalence and identify associations between suicidal ideation and indicators of psychosocial distress and social-environmental factors in Thai adolescents. Using data from the Thailand Global School-Based Student Health Survey (GSHS) 2008, we assessed the prevalence of suicidal ideation and its associated factors among adolescents (N = 2,758). Overall the prevalence of suicidal ideation in the past 12 months was 8.8% (9.9% males and 7.7% females). Variables influenced the suicidal ideation in multivariable analysis were sadness (Odds Ratio = OR: 6.03; 95% Confidence Interval = CI (3.00-12.14), lack of parental attachment (OR = 2.26, CI = 1.09-4.67), current alcohol use (OR = 2.32, 1.21-4.44), and ever having had sexual intercourse (OR = 4.16, CI = 3.40-7.68). Psychosocial, health-risk behaviours and lack of protective factors appear to effect suicidal ideation in this youth population.
