Polydrug use and attempted suicide among Hispanic adolescents in Puerto Rico

Parental education and youth suicidal behaviours: a systematic review and meta-analysis

AIMS

Lower parental education has been linked to adverse youth mental health outcomes. However, the relationship between parental education and youth suicidal behaviours remains unclear. We explored the association between parental education and youth suicidal ideation and attempts, and examined whether sociocultural contexts moderate such associations.

METHODS

We conducted a systematic review and meta-analysis with a systematic literature search in PubMed, PsycINFO, Medline and Embase from 1900 to December 2020 for studies with participants aged 0-18, and provided quantitative data on the association between parental education and youth suicidal ideation and attempts (death included). Only articles published in English in peer-reviewed journals were considered. Two authors independently assessed eligibility of the articles. One author extracted data [e.g. number of cases and non-cases in each parental education level, effect sizes in forms of odds ratios (ORs) or beta coefficients]. We then calculated pooled ORs using a random-effects model and used moderator analysis to investigate heterogeneity.

RESULTS

We included a total of 59 articles (63 study samples, totalling 2 738 374 subjects) in the meta-analysis. Lower parental education was associated with youth suicidal attempts [OR = 1.12, 95% Confidence Interval (CI) = 1.04-1.21] but not with suicidal ideation (OR = 1.05, 95% CI = 0.98-1.12). Geographical region and country income level moderated the associations. Lower parental education was associated with an increased risk of youth suicidal attempts in Northern America (OR = 1.26, 95% CI = 1.10-1.45), but with a decreased risk in Eastern and South-Eastern Asia (OR = 0.72, 95% CI = 0.54-0.96). An association of lower parental education and increased risk of youth suicidal ideation was present in high- income countries (HICs) (OR = 1.14, 95% CI = 1.05-1.25), and absent in low- and middle-income countries (LMICs) (OR = 0.91, 95% CI = 0.77-1.08).

CONCLUSIONS

The association between youth suicidal behaviours and parental education seems to differ across geographical and economical contexts, suggesting that cultural, psychosocial or biological factors may play a role in explaining this association. Although there was high heterogeneity in the studies reviewed, this evidence suggests that the role of familial sociodemographic characteristics in youth suicidality may not be universal. This highlights the need to consider cultural, as well as familial factors in the clinical assessment and management of youth's suicidal behaviours in our increasingly multicultural societies, as well as in developing prevention and intervention strategies for youth suicide.

A Retrospective Cohort Study on the Increasing Trend of Suicide Ideations and Risks in an Opioid-Dependent Population of Puerto Rico 2015-2018

The rate of suicide attempts among people with substance abuse disorders in the U.S. is six times higher than in the general population. The prevalence of suicidal ideations and attempts continues to increase in Puerto Rico, with a significant incidence in substance-abusing populations. This retrospective cohort study evaluate the suicide profile of 4,347 opioid dependent participants in ASSMCA's methadone center in San Juan, PR, from 2015 to 2018 using questions related to suicidal ideation and attempts included in the admission questionnaire. Participants reporting suicide ideation increase from 8.5% in 2015 to 17.0% in 2018. In 2015 only 7.0% claimed to have had a history of a suicide attempt, increasing to 12.4% in 2018. Our data support the need for screening for suicide risk among substance abusing populations to identify targeted interventions. The identification of high-risk populations for suicide can help during rehabilitation and finding the adequate resources needed.

Alcohol use and risk of suicide: a systematic review and Meta-analysis

Objectives: Alcohol use has several consequences and is one of the variables that increase risk of suicide. This meta-analysis was performed using cohort studies to clarify the association of alcohol use and suicide.Method: Scientific sources were reviewed regarding the keywords. After screening, thirty cohort studies were identified for the meta-analysis. The analysis was performed based on the random effects and subsequent analysis of the subgroups, based on various variables.Result: Analysis of the results showed that there is a relationship between alcohol use and suicide. Risk Ratio (RR) between alcohol use and suicide was 1.65. In men, pooled RR was 1.56 with 95% CI = 1.20-2.03, and in women, the pooled RR was equal to 1.40 with 95% CI = 1.11-1.77.Conclusion: Overall, the findings indicate that alcohol use is a risk factor for suicide. Therefore, it seems that prevention and control of alcohol use can be effective in promoting mental health.

Exposure to parental psychopathology and offspring's risk of suicide-related thoughts and behaviours: a systematic review

AIMS

The primary objective of this systematic review was to identify and synthesise analytic studies examining the association between exposure to parental psychopathology in childhood and the nature of subsequent suicide-related thoughts (SRT) and suicide-related behaviour (SRB) (severity of ideation, planned/unplanned attempts/lethality) and to describe the direction, and magnitude of associations. The secondary objective was to determine if the associations from the primary objective differ by the type(s) and timing of parental psychopathology, sex/gender of the parent and child and is mediated by child psychiatric symptoms and family functioning.

METHODS

A systematic review was conducted using guidelines from the PRISMA statement. MEDLINE, CINAHL, EMBASE, psycINFO, Web of Science and grey literature sources were searched by two reviewers to March, 2017. Studies were included if they examined any parental psychopathology (Diagnostic and Statistical Manual of Mental Disorders criteria or equivalent) or SRT or SRB and offspring SRT or SRB occurring from birth <25 years of age.

RESULTS

Out of 10 231 studies identified, 54 were included for review. Studies were clinically and methodologically heterogeneous with none at low risk of bias (ROB). Nine studies with moderate ROB indicated a significantly increased risk of offspring SRT, suicide attempts (SA) and suicide among those exposed to maternal SA and suicide in childhood or adolescence. In the remaining 45 studies with higher ROB this association persisted. Several studies (67%) did not confirm that the exposure occurred in the offspring's childhood or adolescence. Findings were suggestive of a mediating effect of offspring psychiatric symptoms, however, few studies examined mediation and effect modification of contextual variables.

CONCLUSIONS

Offspring exposed to maternal SA are at an increased risk of these same behaviours early in life. Prospective attention to the types and timing of maternal and paternal psychopathology and the intermediate pathways to offspring SRT and SRB onset is needed and could have implications for informing modifiable targets for early intervention and prevention.

Polydrug use by European adolescents in the context of other problem behaviours

Aim

Previous studies of the association between polydrug use and other risk behaviours have generally been limited to specific substances and a small number of behaviours. The aim of this study is to obtain better insight into polydrug use (comprising legal and illegal substances: tobacco, alcohol, tranquillisers/sedatives, cannabis, and other illegal drugs) and its association with co-occurring problem behaviours drawn from various broad domains (sexual, aggressive, delinquent, school achievement, relationships) among European adolescents.

Methods

Data were obtained from 101,401 16-year-old students from 35 European countries participating in the 2011 ESPAD survey. Associations between polydrug use and other problem behaviours were examined by multinomial and binary logistic regression analyses.

Results

Tranquillisers/sedatives appeared among the commonest combinations in the polydrug use pattern, especially for females. A strong trend was found between levels of involvement with polydrug use and other problem behaviours for both genders. The highest associations with polydrug use were for problems with the police, risky sexual behaviour and skipping school. Gender differences showed higher prevalences among boys than girls of problem behaviours of aggressive, antisocial type, while girls prevailed over boys in relationship problems.

Conclusion

An incremental relationship exists between the level of involvement with polydrug use and the co-occurrence of problem behaviours. Preventative interventions should consider the misuse of tranquillisers/sedatives within the context of polydrug use by adolescents and expand their target groups towards multiple problem behaviours.

Substance use disorder and risk of suicidal ideation, suicide attempt and suicide death: a meta-analysis

BACKGROUND

This meta-analysis addressed the association between substance use disorder (SUD) and suicide outcomes based on current evidence.

METHODS

We searched PubMed, Web of Science and Scopus until May 2015. We also searched the reference lists of included studies and Psycinfo website. We included observational (cohort, case-control, cross-sectional) studies addressing the association between SUD and suicide. Our outcomes of interest were suicide ideation, suicide attempt and suicide death. For each outcome, we calculated the odds ratio (OR) or risk ratio (RR) with 95% confidence intervals (CI) based on the random-effects model.

RESULTS

We identified a total of 12 413 references and included 43 studies with 870 967 participants. There was a significant association between SUD and suicidal ideation: OR 2.04 (95% CI: 1.59, 2.50; I² = 88.8%, 16 studies); suicide attempt OR 2.49 (95% CI: 2.00, 2.98; I² = 94.3%, 24 studies) and suicide death OR 1.49 (95% CI: 0.97, 2.00; I² = 82.7%, 7 studies).

CONCLUSIONS

Based on current evidence, there is a strong association between SUD and suicide outcomes. However, evidence based on long-term prospective cohort studies is limited and needs further investigation. Moreover, further evidence is required to assess and compare the association between suicide outcomes and different types of illicit drugs, dose-response relationship and the way they are used.

A comparison of risk factors associated with suicide ideation/attempts in American Indian and White youth in Montana

We examined racial/ethnic and gender-specific associations between suicide ideation/attempts and risky behaviors, sadness/hopelessness, and victimization in Montana American Indian and White youth using 1999-2011 Youth Risk Behavior Survey data. Logistic regression was used to calculate odds ratios and 95% confidence intervals in stratified racial/ethnic-gender groups. The primary results of this study show that although the American Indian youth had more statistically significant suicidal thoughts and attempts than the White youth, they had fewer statistically significant predictors compared to the White youth. Sadness/hopelessness was the strongest, and the only statistically significant, predictor of suicide ideation/attempts common across all four groups. The unhealthy weight control cluster was a significant predictor for the White youth and the American Indian/Alaska Native girls; the alcohol/tobacco/marijuana cluster was a significant predictor for the American Indian boys only. Results show important differences across the groups and indicate directions for future research targeting prevention and intervention.

Suicidal Ideation and Alcohol Use Among Ethiopian Adolescents in Israel

Recent figures point to alarming rates of suicidal tendencies and risk behaviors among Ethiopian adolescents (first and second generation) in Israel. This study tries to understand this phenomenon through an examination of the relationship between ethnic identity (Israeli and Ethiopian) and parental support with suicidal ideation and alcohol use. Two hundred adolescents aged 15–18 years from the Ethiopian community in Israel completed questionnaires examining the degree to which they felt a sense of (positive) Israeli and Ethiopian identity and parental support as well as suicidal ideation, drinking behavior, and depression. Results showed significant correlations between both Israeli and Ethiopian identities and suicidal ideation and alcohol use and a significant relationship between suicidal ideation and parental support. Regression analysis highlighted the pivotal role of a strong and positive heritage (Ethiopian) identity in lower levels of suicidal ideation and alcohol use. Results suggest the important role of ethnic identity for well-being among immigrant and minority youth, in particular in the ability of minority youth to consolidate a coherent ethnic identity incorporating a positive connection to their heritage culture as providing a protective role against suicidal tendencies and risk behaviors.
