Suicide Attempts and Associated Factors in Male and Female Korean Adolescents A Population-Based Cross-Sectional Survey

Understanding and comparing risk factors and subtypes in South Korean adult and adolescent women's suicidal ideation or suicide attempt using survey and social media data

Objective

This study aimed to investigate the similarities and differences in risk factors for suicide among adult and adolescent women in South Korea and identify subtypes of suicidal ideation or suicide attempt in each group.

Methods

Multifaceted data were collected and analyzed by linking survey and social media data. Interpretable machine learning models were constructed to predict suicide risk and major risk factors were extracted by investigating their feature importance. Additionally, subtypes of suicidal adult and adolescent women were identified and explained using risk factors.

Results

The risk factors for adult women were primarily related to mental disorders, while those for adolescent women were primarily related to interpersonal experiences and needs. Two subtypes of suicidal adult women were one with high psychiatric symptoms and mental disorders of them and/or their families and the other with excessive social media use and high online victimization. Two subtypes of suicidal adolescent women were one with high psychiatric symptoms, high ACEs, and high social connectedness, and the other with frequent social media use, high online sexual victimization, and high social assurance.

Conclusions

These findings enable a stratified and targeted understanding of suicide in women and help develop customized suicide prevention plans in South Korea.

Temporomandibular Disorders as a Risk Factor for Suicidal Behavior: A Systematic Review

BACKGROUND

Temporomandibular disorders (TMD) are a group of common musculoskeletal dysfunctions that affect the temporomandibular joint or masticatory muscles and related structures or are expressed as a clinical combination of these two factors. The etiology of TMD is multifactorial and features related to anxiety, depression and mental disorders can contribute to the predisposition, onset and progression of TMD. The ability to adapt and develop coping attitudes was reduced in patients presenting with chronic pain, while suicidal behavior (suicidal ideation, suicide attempts, and suicide completion) was increased. The objective of this review was therefore to investigate suicidal behavior in relation to TMD.

METHODS

The review was performed according to the PRISMA 2020 guidelines. Six databases (PubMed, MEDLINE, EMBASE, Scopus, Ovid, and Google Scholar) were consulted through the use of keywords related to the review topic. The study is registered on PROSPERO (CRD42022320828).

RESULTS

The preliminary systematic search of the literature yielded 267 records. Excluding duplicates, 15 were considered potentially relevant and kept for title and abstract analysis. Only six articles were considered admissible reporting a single exposure factor, TMD and a single outcome, suicidal behavior, although these were evaluated through different assessment tools. We found a low association of TMD with suicidal behavior in observational studies, with estimates partly provided [prevalence ratio (PR) from 1.26 to 1.35, 95% confidence intervals (CI) from 1.15 to 1.19 (lower) and from 1.37 to 1.54 (higher); and odds ratios (OR) from 1.54 to 2.56, 95% CI from 1.014 to 1.157 (lower) and 2.051 to 6.484 (higher)], a relevant sample size (n = 44,645), but a few studies included (n = 6).

CONCLUSIONS

The results of the included studies showed that the prevalence data of suicidal behavior were more present in young adults with TMD, with a controversial association with gender. Suicidal behavior was also correlated and aggravated by the intensity of pain.

Characterization of suicide attempts and self-harm by adolescents and adults notified in Santa Catarina, Brazil, 2014-2018

OBJECTIVE

To characterize adolescent and adult suicide attempts and self-harm reported in Santa Catarina, Brazil, from 2014 to 2018.

METHODS

This was a cross-sectional descriptive study with data from the Notifiable Health Conditions Information System. The sociodemographic, clinical and type of self-inflicted violence characteristics among adolescents and adults were compared.

RESULTS

Among the 8,859 notifications analyzed, suicide attempts predominated in relation to self-mutilation; self-inflected violence was more frequent in females, those of white skin color and with mental disorders; it occurred more at home, in both age groups. Among adolescents, repeated self-mutilation (83.3%) stood out, while among adults, repeated suicide attempts (50.6%) and suspected alcohol use (18.3%) at the time of violence stood out.

CONCLUSION

We identified high prevalence of attempted suicide among adolescents and adults; the characteristics of violence were similar between the age groups analyzed.

Suicidality among child and adolescent psychiatric inpatients: time trend study comparing 2000 and 2011

Child and adolescent inpatient treatment has faced major changes since the year 2000, including shorter inpatient stays and a greater use of psychotropic drugs. This study explored changes and correlates of suicidal threats and suicide acts among inpatients, by comparing Finnish cross-sectional surveys from 2000 to 2011. A questionnaire that explored the background, diagnosis and treatment characteristics of inpatients was sent to all child and psychiatric wards in Finland. The data collection was carried out on specified days in 2000 and 2011. We received comprehensive data on 504 patients from 64/69 (93%) wards in 2000 and on 412 patients from 75/79 (95%) wards in 2011. The Spectrum of Suicidal Behaviour Scale was used to explore suicidality. The prevalence of suicidality did not change in this nationwide study: suicidal threat rates were 38% in 2000 and 37% in 2011, and suicide attempts in both years were 11%. The prevalence of suicidal acts was higher among girls and teenagers, while low general functioning, defined as Children's Global Assessment Scale scores of under 30, was associated with both suicidal threats and acts. Violent acts were associated with both suicidal threats and acts in 2000, but not in 2011. Despite changes in treatment practices and shorter inpatient stays, the prevalence of suicidality in child and adolescent inpatient treatment remained unchanged in Finland in 2000 and 2011.

Suicide mortality among youth in southern Brazil: a spatiotemporal evaluation of socioeconomic vulnerability

Objective:

To conduct a geospatial analysis of suicide deaths among young people in the state of Paraná, southern Brazil, and evaluate their association with socioeconomic and spatial determinants.

Methods:

Data were obtained from the Mortality Information System and the Brazilian Institute of Geography and Statistics. Data on suicide mortality rates (SMR) were extracted for three age groups (15-19, 20-24, and 25-29 years) from two 5-year periods (1998-2002 and 2008-2012). Geospatial data were analyzed through exploratory spatial data analysis. We applied Bayesian networks algorithms to explore the network structure of the socioeconomic predictors of SMR.

Results:

We observed spatial dependency in SMR in both periods, revealing geospatial clusters of high SMR. Our results show that socioeconomic deprivation at the municipality level was an important determinant of suicide in the youth population in Paraná, and significantly influenced the formation of high-risk SMR clusters.

Conclusion:

While youth suicide is multifactorial, there are predictable geospatial and sociodemographic factors associated with high SMR among municipalities in Paraná. Suicide among youth aged 15-29 occurs in geographic clusters which are associated with socioeconomic deprivation. Rural settings with poor infrastructure and development also correlate with increased SMR clusters.

Prevalence and correlates of past 12-month suicide attempt among in-school adolescents in Guatemala

Background

The aim of this investigation was to estimate the prevalence of past 12-month suicide attempts and associated factors among in-school adolescents in Guatemala.

Methods

Cross-sectional data from the 2014 "Global School-based Health Survey (GSHS)" included 4,274 students (median age 14 years, interquartile range=2 years) that were representative of all middle school students in Guatemala.

Results

The prevalence of past 12-month suicide attempt was 16.6%, 12.2% among boys and 20.2% among girls. Among students with a suicide attempt in the past year, 52.8% had a suicide plan in the past year. In adjusted logistic regression analysis, male sex and loneliness were associated with past 12-month suicide attempt, and among boys, none of the variables, and among girls, loneliness and current alcohol use were associated with past 12-month suicide attempt.

Conclusion

A high prevalence and several specific factors associated with suicide attempt were identified which can help in guiding preventive strategies.

Individual and social stress, social capital, and depressive symptoms as predictors of adolescent suicide in South Korea: A mediated moderation model

This study examined the interactive effects of strain induced by individual and social stress and social capital on suicide, highlighting depressive symptoms as mediator in these relationships. This study used data from 5000 adolescents aged 14-18 years. Strain due to individual stress was found to have a direct effect on suicide, but strain due to social stress did not have a direct effect on suicide. The interactive effect of strain and social capital significantly predicted depressive symptoms and suicide. In the relationship between strain and suicide, the interactive effect of strain and social capital was mediated by depressive symptoms.

Association between illegal use of substances and suicidal behavior in school students: An integrative review of empirical data

PURPOSE

Investigation of the association between type of suicidal behavior and type and frequency of illegal use of substances (IUS) among school students (aged between 12 and 18 years), with a focus on gender differences.

DESIGN AND METHODS

A systematic review in PubMed, CINAHL, PsychINFO, and Scopus was performed. Identified articles were published between 2007 and 2018.

RESULTS

Twenty empirical studies confirmed the association between IUS and suicidality, strongly differentiated between males and females, highlighting the importance of gender-specific mediating factors.

CONCLUSIONS

Mental health nurses need to document gender factors, frequency, and motivation of IUS when screening adolescents experiencing suicidal behavior and IUS.

Prevalence, distribution, and associated factors of suicide attempts in young adolescents: School-based data from 40 low-income and middle-income countries

Suicide attempts are the most important known predictor of death by suicide. The aim of this study is to examine the prevalence, distribution, and associated factors of suicide attempts among young adolescents in 40 low-income and middle-income countries. We used data from the Global School-Based Student Health Survey (2009–2013) and a nationally representative study in China (2010), which are school-based surveys of students primarily aged 12–18 years that assess health behaviors using an anonymous, standardized, self-reported questionnaire. We calculated the prevalence of suicide attempts in young adolescents from 40 low-income and middle-income countries using the surveys. Multilevel logistic models were used to estimate the associations between suicide attempts and potential risk factors, adjusting for gender, age, school and survey year. Results show that the mean 12-month prevalence of suicide attempts was 17.2%, ranging from 6.7% in Malaysia to 61.2% in Samoa. The overall prevalence of suicide attempts was higher for girls than for boys (18.2% vs 16.2%, P<0.05). Among the suicide attempts, the proportion of suicide attempts with a plan was higher for girls than for boys (62.7% vs 53.2%, P<0.05). Both the prevalence of suicide attempts and the proportion of suicide attempts with a plan increased with age. Factors associated with suicide attempts included poor socioeconomic status, history of bullying, loneliness and anxiety, tobacco and alcohol use, and weak family and social relationships. In conclusion, suicide attempts are frequent among young adolescents in low-income and middle-income countries. Girls and older adolescents tend to make suicide attempts with a plan. The data demonstrate the need to strengthen suicide intervention and prevention programs for young adolescents in low-income and middle-income countries.

Association of temporomandibular disorder and high frequency of suicide ideation in Korean adolescents: a cross-sectional survey

BACKGROUND

This study investigated the association between psychological factors and temporomandibular disorder (TMD) in a representative sample using data from the Korean nationwide survey.

METHODS

The study included 1337 adolescents. Participants provided demographic, socio-economic and behavioural information, and responses to questionnaires assessing their mental health status including perceived stress, depressed mood and suicidal ideation in the presence of TMD. In univariate analysis, t-test was used to test the association between TMD and risk factors by gender in a complex sampling design. Multivariate logistic regression analyses were used to examine the association between TMD and psychological factors.

RESULTS

Male adolescents with TMD were highly engaged with depressed mood and suicidal ideation (p = .0006, p = .0223), however, no psychological factors were significant in female adolescents (p < .05). Male adolescents with both depressed mood and suicidal ideation had significantly high rates of TMD (p = .0024). The risks for experiencing depressed mood (OR: 3.07) and suicidal ideation (OR: 2.564) were significantly associated with TMD in male adolescents after adjusting confounders.

CONCLUSIONS

The results provide evidence that the depressed mood and suicidal ideation were associated with TMD in male adolescents. This study has important implications for enhanced screening and evaluation of mental health among patients with TMD according to gender.

Menarche, menstrual problems and suicidal behavior in Chinese adolescents

BACKGROUND

Menarche is the first menstrual cycle. Menstrual problems, such as dysmenorrheal menorrhagia, oligomenorrhea, and irregular cycle are common in female adolescents. This research aims to examine the associations between age at menarche and menstrual problems and suicidal behavior among Chinese female adolescents.

METHODS

An epidemiological survey of 5831 female adolescents from eight high schools of three counties of Shandong province, China, was conducted. A self-administered paper-and-pencil questionnaire was used to collect information. Logistic regression analyses were used to examine the association between menstruation and suicidality.

RESULTS

The mean age of the sample was 15.02 (SD=1.44) years. Of the sample, 5,231 (90.0%) had experienced their first menstrual cycle, and 23.2%, 10.4%, and 4.5% of the sample reported having had suicidal ideation, plan and attempt, respectively. In multivariate models, menarche at ≤11 years was associated with increased risk of suicidal ideation (OR=1.41, 95%CI: 1.10-1.81) and menarche at 12 years was associated with suicide plan (OR=1.23, 95%CI: 1.00-1.51). Irregular menstrual cycle was significantly associated with increased risk of suicidal ideation (OR=1.40, 95%CI: 1.05-1.86) and menstrual period less than or equal to 4 days was significantly associated with increased risk of suicide plan (OR=1.32, 95%CI: 1.06-1.66).

LIMITATIONS

This cross-sectional study cannot establish the causal directions between menstrual problems and suicidality in adolescents.

CONCLUSIONS

Our study suggests that earlier menarche, irregular menstrual cycle and short menstrual period are associated with suicidal behavior in female adolescents. Further research is warranted to examine the causal relationship between menstrual problems and suicidal behavior in adolescents.

Development and preliminary evaluation of culturally specific web-based intervention for parents of adolescents

WHAT IS KNOWN ON THE SUBJECT?: Problematic parent-child relationships have been identified as one of the main predictors of adolescents' mental health problems, but there are few existing interventions that address this issue. The format and delivery method of existing interventions for parents are relatively inaccessible for parents with full-time jobs and families living in rural areas. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: The newly developed 'Stepping Stone' culturally specific web-based intervention, which is intended to help Korean parents of adolescents to acquire both knowledge and communication and conflict management skills, was found to be feasible and well-accepted by parents. This study enabled us to identify areas for improvement in the content and format of the intervention and strategies. This will potentially increase effect sizes for the outcome variables of parents' perception and behaviours. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: This web-based intervention could be delivered across diverse settings, such as schools and community mental health centers, to increase parents' knowledge of adolescent's mental health and allow for early detection of mental health problems. Mental health nurses working in schools may spend a significant amount of time addressing students' mental health issues; thus, this web-based intervention could be a useful resource to share with parents and children. In this way, the mental health nurses could facilitate parental engagement in the intervention and then help them to continue to apply and practice the knowledge and skills obtained through the program.

ABSTRACT

Introduction There is a need for accessible, culturally specific web-based interventions to address parent-child relationships and adolescents' mental health. Aims This study developed and conducted a preliminary evaluation of a 4-week web-based intervention for parents of adolescents aged 11 to 16 years in Korea. Methods We used a two-group, repeated measures, quasi-experimental study design to assess the feasibility of developing and implementing a web-based intervention for parents. Descriptive statistics, chi-square and t tests, and mixed effect modeling were used for data analysis. Results The intervention and 1-month follow-up survey were completed by 47 parents in the intervention group and 46 parents in the attention control (AC) group. The intervention was found to be feasible and well-accepted by parents. Discussion This culturally specific web-based intervention is a useful tool for knowledge dissemination among large numbers of parents. Areas for improvement in the content and format of the intervention and strategies to elicit significant parent-child interactions are provided. Implications for practice and conclusion The intervention could be disseminated in collaboration with mental health nurses working in schools to facilitate parents' participation.
