Suicidal behaviour in adolescents: Educational interventions in Mexico

Suicide Risk Factors in High School Students

In Mexico, suicide has become an important public health problem, representing the third leading cause of death in the adolescent population. Suicidal behavior in adolescents is associated with the interaction of complex relationships between personal, interpersonal, and sociocultural factors. Through a quantitative, descriptive, and correlational cross-sectional study, the present study aimed to analyze the prevalence and risk factors associated with suicidal ideation among adolescents from different high schools of the high school system (SEMS) of the University of Guadalajara, in response to the psychosocial impact of the COVID-19 pandemic. A descriptive statistical analysis was carried out on the data obtained from the 3583 students surveyed, followed by a principal component analysis (PCA) to identify closely related social, emotional, and behavioral variables. The PCA yielded eight principal components, which together represent 75.42% of the variance across psychometric tests. A multiple linear regression analysis was used, with a regression value (R2) of 0.4811, indicating that the explanatory model can predict 48.1% of the variability in suicidal ideation, with a statistical significance level of 0.05. According to the studies conducted, 19% (688 students) showed indicators of high suicide risk and 26.8% (960 students) showed moderate risk. Depression, mental health, health-related quality of life, physical and psychological well-being, and mood and emotions are the most influential factors in suicidal ideation.

A scoping review of the implementation and cultural adaptation of school-based mental health promotion and prevention interventions in low-and middle-income countries

Effective school-based mental health promotion and prevention interventions in low-and middle-income countries (LMICs) can positively impact the mental health and well-being of large numbers of young people. This scoping review aimed to investigate the implementation of effective mental health promotion and prevention interventions in LMIC schools. A scoping review of the international literature was conducted and followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews guidelines. Medline, PsycInfo, Scopus, Embase, CINAHL and Cochrane were searched for peer-reviewed literature published from 2014 to 2022. PsycExtra, Google Scholar and the websites of key organisations were searched for relevant grey literature. Study selection focussed on mental health promotion interventions, including the development of social and emotional skills and mental health literacy, and prevention interventions, including anti-bullying and skill-based interventions for "at-risk" students. Twenty-seven studies evaluating 25 school-based interventions in 17 LMICs were included in the review. Fifteen interventions were developed in the implementing country and 10 were adapted from high-income countries (HICs) or other settings. Findings from the studies reviewed were generally positive, especially when interventions were implemented to a high quality. Universal life-skills interventions were found to increase social and emotional skills, decrease problem behaviours and positively impact students' mental health and well-being. Mental health literacy interventions increased mental health knowledge and decreased stigma among students and school staff. Outcomes for externally facilitated anti-bullying interventions were less positive. All 19 effective studies reported on some aspects of programme implementation, and 15 monitored implementation fidelity. Eleven studies outlined the programme's underpinning theoretical model. Only four studies reported on the cultural adaptation of programmes in detail. Including young people in the adaptation process was reported to facilitate natural cultural adaptation of programmes, while input from programme developers was considered key to ensuring that the core components of interventions were retained. The review findings indicate increasing evidence of effective mental health interventions in LMIC schools. To facilitate the sustainability, replication and scaling-up of these interventions, greater attention is needed to reporting on intervention core components, and the processes of implementation and cultural adaptation in the local setting.

Prevalence of suicidal behavior in adolescents in India: A systematic review and meta-analysis

BACKGROUND

Suicidal behaviour (SB) in adolescents is an emerging public health issue globally. The present study was undertaken to estimate the overall prevalence of SB among the adolescents (10-19 years of age) in India.

DATA SOURCES

In this systematic review and meta-analysis (SRMA), an extensive literature search in PubMed, Scopus, EBSCO, Web of Science, ProQuest, Embase, Cochrane, and preprint servers (medRxiv, arXiv, bioRxiv, BioRN, ChiRxiv, ChiRN, and SSRN) and assessment of all published articles until 28th February 2023 as per the PROSPERO registration protocol (CRD42023385550), was undertaken.

STUDY SELECTION, DATA EXTRACTION, AND SYNTHESIS

Studies from India which reported the prevalence of suicidal ideation, suicide attempt, and suicidal plan were included. The quality of the included studies was assessed by risk of bias assessment tool. R version 4.2 was used to conduct all the relevant analyses. Heterogeneity was assessed, and a random effects model for estimating the pooled prevalence of the outcomes was applied. Subgroup analyses were planned based on region, locality (urban/rural) and the study settings (educational institutions/community-based). A meta-regression to analyze the effects of potential moderators on outcomes was done. Sensitivity analyses were planned based on the removal of outliers and poor-quality studies. Publication bias was tested by Doi plot and LFK index.

MAIN OUTCOMES

Pooled prevalence of suicide attempts, suicide ideations and suicide plans RESULTS: A total of 20 studies were identified as eligible for the systematic review, and 19 studies were identified as eligible for the meta-analysis. The pooled prevalence of suicidal ideation was estimated to be 11% (95 % CI 7-15); heterogeneity between the studies was high (I² 98 %, p < 0.01). The pooled prevalence of suicidal attempts and suicidal plan was estimated to be 3 % each (95 % CI 2-5); with heterogeneity being high (I² 96 %, p < 0.01). Subgroup analysis revealed a significant variation in suicidal ideation and attempts between different regions of India (South > East > North), and higher prevalence among the educational-institute-based settings and urban areas.

CONCLUSION

Overall, the prevalence of suicidal behavior among the adolescents in India is high, and they experience all types of suicidal behavior (ideations, plans and attempts).

Comparative Analysis of Lifetime Suicide Attempts among Mexican Adolescents, over the Past 12 Years

OBJECTIVE

To compare the occurrence of suicide attempts across nationally representative samples of the Mexican adolescent population over the past 12 years, and to analyze its association with sociodemographic, lifestyle and mental-health indicators.

METHODOLOGY

Data were drawn from the 2006, 2012 and 2018 National Health and Nutrition Surveys (n = 25,056; 21,509; and 17,925 adolescents, respectively). Estimates were based on standardized measurements.

RESULTS

The estimated lifetime prevalence rates of suicide attempts were 1.1% in 2006, 2.7% in 2012, and 3.9% in 2018, indicating a 3.4-fold increase. Across the three survey periods, women yielded rates nearly three times higher than men. Lifetime prevalence grew the most among adolescents aged 13-15 years. Compared to the other respondents, the odds of lifetime suicide attempts proved seven times as high for those who had been sexually abused during their childhood, five times as high for those who had been diagnosed with a depressive disorder, three times as high for those who had suffered physical aggression and twice as high for those who had smoked 100+ cigarettes in their lifetimes and those who consumed alcohol.

CONCLUSION

The sharp increase in suicide attempts in Mexico calls for an urgent public-health response via universal and targeted interventions supported by national policy and sustained federal funding.

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.
