Relationships between Multimorbidity and Suicidal Thoughts and Plans among Korean Adults

Physical multimorbidity, suicidal ideation, and suicide attempts among adults aged ≥50 years from low- and middle-income countries

OBJECTIVES

The association between physical multimorbidity and suicidal ideation or suicide attempts among older adults from low- and middle-income countries (LMICs) is largely unknown. We aimed to assess this association as well as its mediators using nationally representative data from six LMICs.

METHODS

Cross-sectional, community-based data from the Study on Global Aging and Adult Health were analyzed. A total of 11 chronic physical conditions were assessed. Self-reported information on past 12-month suicidal ideation and suicide attempts was also collected. Multivariable logistic regression and mediation analyses were conducted.

RESULTS

The final sample consisted of 34,129 adults aged ≥50 years (mean [SD] age 62.4 (16.0) years; maximum age 114 years; 52.1% females). In the overall sample, physical multimorbidity was associated with increased odds for suicidal ideation (OR = 2.99; 95% CI = 2.06-4.34) and suicide attempts (OR = 2.79; 95% CI = 1.58-4.95), with the association being stronger in males than females. The association between multimorbidity and suicidal ideation or suicide attempts was largely mediated by pain/discomfort (mediated% 33.3%-44.2%), sleep/energy (28.2%-33.8%), and mobility limitations (26.6%-34.8%).

CONCLUSIONS

Physical multimorbidity among older adults in LMICs was associated with a substantially increased risk for suicidal ideation and suicide attempts. Addressing the identified mediators in people with physical multimorbidity may aid in the prevention of suicidal ideation and suicide attempts.

The association of physical multimorbidity with suicidal ideation and suicide attempts in England: A mediation analysis of influential factors

BACKGROUND

Suicide is one of the most important causes of deaths in the United Kingdom, and the numbers are currently increasing.

AIM

There are numerous identified determinants of suicidality, and physical multimorbidity is potentially important but is currently understudied. Thus, this study aims to investigate the association of physical multimorbidity with suicidality.

METHODS

Cross-sectional data from the Adult Psychiatric Morbidity Survey 2007, which was conducted in England between October 2006 and December 2007 by the National Center for Social Research and Leicester University were analyzed. Respondents were asked about 20 physical health conditions, and suicidal ideation and suicide attempts were assessed.

RESULTS

Out of 7,403 individuals aged 16 years or over, the prevalence of physical multimorbidity, suicidal ideation, and suicide attempts were 35.1%, 4.3%, and 0.7%, respectively. After adjustment for potential confounders, compared to no physical conditions, 1, 2, 3, and ⩾4 conditions were associated with significant 1.79 (95% CI [1.25, 2.57]), 2.39 (95% CI [1.63, 3.51]), 2.88 (95% CI [1.83, 4.55]), and 6.29 (95% CI [4.12, 9.61]) times higher odds for suicidal ideation. Mediation analysis showed that cognitive problems (mediated percentage 39.2%) and disability (37.5%) explained the largest proportion between multimorbidity and suicidal ideation. Pain (38.0%) and cognitive problems (30.7%) explained the largest proportion between multimorbidity and suicide attempts.

CONCLUSION

In this large sample of UK adults, physical multimorbidity was associated with significantly higher odds for suicidal ideation and suicide attempts. Moreover, several potential mediators were identified, and these may serve as future targets for interventions that aim to prevent suicidality among people with physical multimorbidity.

Physical multimorbidity and wish to die among adults aged ≥65 years: A cross-sectional analysis of the Irish Longitudinal Study on Ageing

BACKGROUND

Physical multimorbidity (i.e., ≥2 chronic conditions) may induce feelings of wish to die (WTD), but there is limited literature on this topic, while the mediators in this association are largely unknown. Thus, the aim of the present study was to investigate this association and its mediators among older Irish adults.

METHODS

Cross-sectional, nationally representative data from Wave 1 of the Irish Longitudinal Study on Ageing 2009-2011 were analyzed. Information on self-reported lifetime diagnosis of 14 chronic physical conditions were obtained. WTD was defined as answering affirmatively to the question "In the last month, have you felt that you would rather be dead?" Multivariable logistic regression and mediation analyses were conducted.

RESULTS

Data on 2941 adults aged ≥65 years [mean (SD) age 73.2 (5.2) years; 45.0 % males] were analyzed. Physical multimorbidity was associated with 3.39 (95%CI 1.58, 7.28) times higher odds for WTD. This association was largely explained by pain (% mediated 28.1 %), followed by depression (19.4 %), sleep problems (18.4 %), perceived stress (13.0 %), loneliness (10.4 %), anxiety (8.1 %), and disability (7.2 %).

CONCLUSIONS

Multimorbidity was associated with increased odds for WTD among Irish older adults. Addressing the identified mediators may contribute to reducing feelings of WTD among older adults with multimorbidity.

Physical multimorbidity and lifetime suicidal ideation and plans among rural older adults: the mediating role of psychological distress

BACKGROUND

Previous studies have revealed that single physical chronic condition was associated with suicidal ideation/plans, but few studies have examined the relationship between multimorbidity and suicidal ideation/plans, and no studies have explored the underlying potential mechanism on this relationship in China. This study aimed to explore association between physical multimorbidity and suicidal ideation as well as plans, and further examine the mediating role of psychological distress (PD) on this relationship.

METHODS

This study was based on the data from a survey about the health service of rural elderly household in Shandong, China. A total of 3242 adults aged 60 years and older were included in this study. PD was measured by Kessler Psychological Distress Scale (K10). Ordinal and binary logistic regression analyses were employed to explore the association between physical multimorbidity, PD and suicide ideation/plans. Bootstrapping analysis was further used to examine the mediation effect of PD on the association of multimorbidity and suicidal ideations/plans.

RESULTS

The prevalence of multimorbidity, lifetime suicidal ideation, and suicidal plan in rural older adults was 35.2, 10.6 and 2.2%, respectively. Older adults living in rural areas with two or more chronic physical conditions experienced significantly higher risk of suicidal ideation and suicidal plans. The association between multimorbidity and suicidal ideations/plans was partially mediated by PD, of which, the mediating effect of PD accounted for 31.7 and 25.5% of the total effect, respectively.

CONCLUSION

This study demonstrated the associations between physical multimorbidity and suicidal ideation/plans, and the mediating role of PD on this relationship among Chinese rural elderly. Healthcare providers in rural community should provide regular surveillance for the mental health status among the rural elderly with multimorbidity, and carry out various effective intervention measures to improve the mental health status, so as to reduce the risk of suicide.

The relationship between multimorbidity and suicidal ideation: A meta-analysis

OBJECTIVE

Multimorbidity refers to the individual has two or more medical conditions, which include physical multimorbidity (two or more physical conditions), mental multimorbidity (two or more mental conditions) and physical and mental multimorbidity (one or more mental and one or more physical conditions). This study is to assess the relationship between multimorbidity and suicidal ideation (SI) by conducting a meta-analysis.

METHODS

Through using subject word and random word, Web of Science, Cochrane Library and PubMed were searched for related records up to March 2020. The Newcastle-Ottawa scale and the Agency for Healthcare Research and Quality were used to evaluate the quality of included studies. Subgroup and sensitivity analysis were performed. The publication bias was evaluated by the funnel plots, Begg's test and Egger's test.

RESULTS

A total of 19 studies were included for analysis. The pooled odd ratio (OR) for the association between multimorbidity and SI was 2.90 (95%CI 2.29-3.67, P < .001). Subgroup analysis based on nature of study, category of multimorbidity, country, whether adjusted the covariates, and quality ratings was performed. The result of sensitivity analysis indicated that no individual studies had a substantial impact on the pooled OR. There was no publication bias in the studies.

CONCLUSIONS

Multimorbidity is one important factor in increased risk of SI. It is critical to assessing SI among patients with multimorbidity in primary care and specialty medical practices, particularly among physical and mental multimorbidity patients who may have higher risk of SI.
