Modifying effect of suicidal ideation on the relationship between asthma and cigarette use behaviors among Korean adolescents

Association between Asthma and Suicidality in 9-12-Year-Old Youths

PURPOSE

Suicidal ideation and attempts in youth are a growing health concern, and more data are needed regarding their biological underpinnings. Asthma is a common chronic inflammatory disorder in youth and has been associated with suicidal ideation and attempts in adolescent and adult populations, but data in younger children and early adolescents are lacking. We wished to study associations of asthma with childhood suicidality considering asthma's potential as a clinically relevant model for childhood chronic immune dysregulation.

METHODS

Using data from the Adolescent Brain Cognitive Development (ABCD) Study (n = 11,876, 47.8% female, mean age 9.9 years at baseline assessment and 12.0 years at two-year follow-up), we assessed associations between asthma and suicidal ideation and attempts through baseline to two-year follow-up.

RESULTS

Asthma history as defined by parent report (n = 2282, 19.2% of study population) was associated with suicide attempts (SA) (odds ratio (OR) = 1.44, p = 0.01), and this association remained significant even when controlling for demographics, socioeconomic factors, and environmental factors (OR = 1.46, p = 0.028). History of asthma attacks was associated with both suicidal ideation (SI) and SA when controlling for demographics, socioeconomic factors, and environmental factors (OR = 1.27, p = 0.042; OR = 1.83, p = 0.004, respectively). The association of asthma attack with SA remained significant when controlling for self-reported psychopathology (OR = 1.92, p = 0.004). The total number of asthma attacks was associated with both SI and SA (OR = 1.03, p = 0.043; OR = 1.06, p = 0.05, respectively).

CONCLUSIONS

Findings suggest an association between asthma and suicidality in early adolescence. Further research is needed to investigate mechanisms underlying this relationship.

[Asthma and suicidal behavior in adolescents: a literature review]

INTRODUCTION

Adolescence is a difficult time in life and asthma has major psychological consequences for adolescents.

OBJECTIVES

This systematic literature review focused on the association between asthma and suicidal behaviors (suicidal ideations [SI], suicide plans [SP] and suicide attempts [SA]) among adolescents in the general population.

METHOD

Research on Medline for the 1980-2021 period. Objectives This systematic literature review focused on the association between asthma and suicidal behaviors (suicidal ideations [SI], suicide plans [SP] and suicide attempts [SA]) among adolescents in the general population.

RESULTS

An overwhelming majority of the studies taken into consideration demonstrated a significant positive association between asthma and suicidal behaviors. Among the 10 studies assessing SI (with or without SP), 9 of them found a significant positive association between asthma and SI. Eight studies assessed SA; five cross-sectional studies and one prospective study demonstrated a significant positive association between asthma and SA. Only one case-control study did not find a significant positive association between asthma and SA after hospitalization for asthma. The two cross-sectional studies assessing suicidal risk taken as a whole (SI, SP and SA) demonstrated a significant positive association between asthma and at least one suicidal behavior. (OR=1.71; P<0.001). However, several studies did not include depression as an adjustment factor.

CONCLUSION

It is important that healthcare professionals assess suicide risk in adolescent suffering from asthma, the objective being to avoid SA or death from SA.

Suicidality among patients with asthma: A systematic review and meta-analysis

BACKGROUND

Asthma is associated with multiple psychiatric comorbidities. However, the relationship between asthma and suicidality has not be well established.

METHODS

According to the PRISMA guidelines, protocol of the study was registered in the PROSPERO database (CRD42019123150). A systematic search of the PubMed, Embase and PsycINFO databases was performed for relevant studies published from its inception to January 25, 2019. Studies that reported the risk of suicidal ideation, attempts and mortality in asthmatics compared with non-asthmatics were included. A random-effects model was used to synthesize the estimates and the quality of the included studies was assessed under the Newcastle-Ottawa Scale.

RESULTS

Twenty-eight studies including 2,759,841 asthmatic patients and 16,290,362 non-asthmatic controls were pooled and analyzed in the current study. The pooled data showed that asthmatic patients had increased risk of exhibiting suicidal ideation (OR, 1.52; 95%CI, 1.37-1.70), suicide attempts (OR, 1.60; 95%CI, 1.33-1.92) and suicide mortality (OR, 1.31; 95%CI, 1.11-1.55) compared to non-asthmatic controls. Noticeably, adolescent asthmatic patients had a more than 2-fold risk of suicide mortality compared to non-asthmatic controls (OR, 2.14; 95%CI, 1.61-2.83).

LIMITATIONS

The limitations of the present study were variability in study designs and various measures of asthma and suicidality, which possibly contribute to notable heterogeneity.

CONCLUSIONS

Patients with asthma have a significantly increased risk of suicidal ideation, suicide attempts and suicide mortality. Clinical physicians should pay more attention to the increased risk of suicidality in asthmatics, screen for these suicidal thoughts and behaviors, and make appropriate mental health referrals when necessary.

Asthma and other allergic diseases in relation to suicidal behavior among South Korean adolescents

OBJECTIVES

Adolescent asthma can be the cause of social and psychological problems. We investigated the association between asthma with other allergic diseases and suicidal risk behavior among South Korean adolescents using nationally representative data.

METHODS

Web-based self-report data from the Korean Youth Risk Behavior Web-Based Survey were used in this study (N = 237,022). Complex sample logistic regression was used to define the relationship between suicidal behavior and asthma (n = 7177), with other allergic diseases [asthma with allergic rhinitis (AR) or asthma with atopic dermatitis (AD) (n = 9720), asthma with AD and AR (n = 4971)].

RESULTS

Participants with asthma and other allergies showed a higher prevalence of substance use, greater sexual experience, greater perceived stress, poorer perceived health, more severe depression, more suicidal ideation, and more suicide attempts than those without allergy. Depression, suicidal ideation, and suicide attempts increased trend in the following order: no asthma, asthma only, asthma with one other allergy (asthma with AD or asthma with AR), and asthma with AD and AR. After adjusting for multiple confounders, the odds ratio for suicidal ideation with asthma and AD and AR was 1.13 [95% confidence interval (CI), 1.06-1.19] and that for suicide attempts was 1.31 (95% CI, 1.20-1.43).

CONCLUSIONS

Adolescent asthma and other allergies were associated with suicidal behavior.

The relationship between asthma and suicidal behaviours: a systematic literature review

Asthma is a highly prevalent chronic condition worldwide, and is particularly common in younger people compared to other chronic conditions. Asthma can result in a number of symptoms that are detrimental to the quality of life of sufferers. The aim of the present systematic literature review was to analyse the existing literature on the relationship between asthma and fatal and nonfatal suicidal behaviours. Articles were retrieved from Scopus, PubMed, ProQuest and Web of Knowledge. We searched for the terms (suicid* OR self-harm) AND (asthma* OR "bronchial hyperreactivity") published in English-language peer-reviewed journals between 1990 and December 2014. Original research papers providing empirical evidence about the potential link between asthma and suicidal behaviours were included. The initial search identified 746 articles. Specific limiting criteria reduced the number of articles to the 19 articles that were finally included in the systematic review. The review found a potential link between asthma and suicide mortality, ideation and attempts across the age groups. Limitations of the review include the restriction to English-language papers published within the chosen time period, the limited number of papers involving suicide mortality, and the fact that the majority of papers originated from the USA.
