Epidemiology and temporal trend of suicide mortality in the elderly in Jiading, Shanghai, 2003-2013: a descriptive, observational study

Investigation of the trend and related factors of suicide attempts and suicide deaths in southeast Iran during 2018-2022

Suicide is a major public health challenge worldwide with an increasing trend. Identifying risk factors for suicide attempts and suicide deaths may help find useful ways to prevent suicide. We aimed to determine the trend and related factors of suicide attempts and suicide deaths in Rafsanjan. This retrospective study included all suicide cases from 2018 to 2022 in Rafsanjan, a city in the southeast of Iran. The information was extracted from the suicide registration system of Rafsanjan University of Medical Sciences. Univariable and multivariable logistics regression models were used to investigate factors affecting suicide death. A total of 2039 cases of suicide, including 1932 cases (94.75%) of suicide attempts and 107 cases (5.25%) of suicide deaths were recorded during the study period. The frequency of suicide deaths and suicide attempts per 100,000 people increased in 2022 compared to 2018 in both genders. In the adjusted model, the odds of suicide deaths in males was 6.48 (95% CI 3.39-12.42) times higher than in females. Also, the odds of suicide deaths in unemployed subjects and housewives were 2.64 (95% CI 1.50-4.67) and 7.45 (95% CI 3.08-18.07) times higher than employed subjects respectively. Finally, people with education less than a diploma had 10.85 (95% CI 1.48-79.54) times higher odds of suicide deaths compared to people with university education. The present research showed that the pattern of suicide has been increasing since 2018, and we may see an upward trend in the coming years, which requires further investigation and preventive measures. Male gender, low education level, unemployment, and being a housewife were associated with the highest frequency of suicide death.

A comparative analysis of antidepressant and anti-suicidal effects of repeated ketamine infusions in elderly and younger adults with depression

OBJECTIVES

This study aims to investigate the differences in safety and antidepressant effects of multi-infusion ketamine treatment between elderly and young adults with depression.

METHODS

The safety, antidepressant, and anti-suicidal effects of multi-infusion ketamine were compared between 19 elderly (≥50 years) and 116 younger (<50 years) adults with depression; all were treated with six ketamine infusions (0.5 mg/kg). Montgomery-Åsberg Depression Rating Scale (MADRS) was used to measure the depressive symptoms, and suicidal ideation was measured with Beck Scale for Suicide Ideation (SSI)-part 1, Hamilton Rating Scale for Depression (HAMD) item 3, and (MADRS) item 10. Dissociative and psychotomimetic symptoms were evaluated based on the Clinician-Administered Dissociative States Scale (CADSS) and the Brief Psychiatric Rating Scale (BPRS)-four items.

RESULTS

Multi-Ketamine infusions resulted in a lower (trend) antidepressant response (37.1 % versus 57.8 %) and antidepressant remission (15.8 % versus 47.4 %) in elderly patients with depression compared with younger patients with depression (all ps > 0.05). Interestingly, elderly patients with depression had a higher MADRS score after six ketamine infusions compared with younger patients (p = 0.04). No significant differences in SSI-part 1 scores, HAMD item 3 scores, MADRS item 10 scores, CADSS scores, and BPRS-four items scores were found between the two groups at any assessment point (all ps > 0.05).

CONCLUSION

Our study shows that repeated-dose infusions of ketamine may be a feasible treatment strategy in elderly Chinese patients with depression; however, elderly patients with depression may be less responsive to ketamine compared with younger adults with depression.

Trends of suicide rates by gender and residence in China from 2002 to 2019

Objective

China has undergone tremendous social changes in the last few decades. This study aimed to research the trends of the suicide rates from 2002 to 2019, and to differentiate effects attributable to age, period, and cohort by gender and residence in China.

Methods

Suicide mortality data were obtained from China's Ministry of Health Vital Registration System. Joinpoint regression model was used to estimate the average annual percentage change (AAPC) of the suicide rates and ratios by gender and residence. The age-period-cohort framework was performed to analyze the underlying mechanisms for suicide mortality trends.

Results

Over the observation period, the significant decrease in suicide mortality rates in China for the economic development and urbanization was observed but to different degrees across gender and regional subgroups. The male-to-female ratio of suicide rates increased year by year (AAPC: 1.9%, 95% CI: 0.2% to 3.7%) while the urban-rural ratio changed little (AAPC: 0.9%, 95% CI: -1.8% to 3.7%). The age-period-cohort analysis revealed a marked increased effect of age and overall decreased effect of both period and cohort on suicide mortality rates. However, the recent cohort has presented an inversely increasing effect.

Conclusion

The suicide rate has fallen sharply in China which has undergone tremendous socioeconomic changes. The varied changes in the suicide rate of different residence-, gender-, and age-groups as well as the age, period, and cohort effect on suicide risk further indicate the relationship of development and the suicide rates may be neither static nor identical on different subgroups in a rapidly changing society.

Suicidal behaviour in older age: A systematic review of risk factors associated to suicide attempts and completed suicides

In older age, several observational studies investigated risk factors for suicide attempts/completed suicides; however, contrasting evidence came from population-based setting. In the present systematic review, we described through a narrative synthesis the significant associations existing among risk factors and suicide attempts/completed suicides in subjects aged >65 years. From the 39 population-based studies selected in six different databases until February 15, 2021, we analyzed the most frequent 28 risk factors for suicidal behaviour. The risk factors more associated to suicide attempts than other variables frequently related to suicidal behavior in older age were: depressive disorders, methods employed to self-harm (particularly poisoning), and psychotropic drug utilization followed by psychological factors and disability. Moreover, male sex, violent methods to self-harm, any psychiatric disorder (depression, anxiety and bipolar disorders), a poor medical condition, stressors/bereavement, and living alone appeared to be more significant for predicting completed suicides in late life. In older age, efforts for suicide prevention should be based on strategies to assess and treat psychiatric disorders along with psychological interventions, particularly in males.

Prevalence of mental disorders among elderly men: a systematic review and meta-analysis

BACKGROUND

Elderly men have been characterized as a group vulnerable to suicide, motivated by loneliness, loss of loved ones and feelings of uselessness to family members.

OBJECTIVES

To ascertain the prevalence of different mental disorders among elderly men who attempted suicide.

DESIGN AND SETTING

Systematic review of observational studies developed as a result of a partnership between two postgraduate schools (Lagarto and Uberlândia).

METHODS

An electronic search was performed in eight electronic databases, including "grey literature", in January 2019. Observational studies that assessed mental disorders among men older than 60 years who attempted suicide were eligible for inclusion.

RESULTS

Among the disorders evaluated, mood disorders had the highest prevalence (42.0%; 95% confidence interval, CI: 31.0-74.0%; I2: 0.0%; P = 0.763), followed by substance use-related disorders (41.0%; 95% CI: 8.0-74.0%; I2: 96.4; P < 0.001) and, lastly, schizophrenic disorders (5.0%; 95% CI: 0.0%-14.0%; I2: 80.3%; P = 0.024).

CONCLUSIONS

It seems that mood disorders and substance use-related disorders are quite prevalent among elderly men with mental disorders who attempted suicide. It is important to consider the role of healthcare services in making early diagnoses of mental disorders among elderly men, in order to diminish the chances of suicide attempts among them.

The Suicide Rate in the Elderly Population of Iran between 2008 and 2014

Background: We aimed to investigate the suicide rate led to death in the elderly population of Iran between 2008 and 2014.

Study design: A cross-sectional study.

Methods: The present study was conducted on all suicide-related deaths in elderly people (≥65 yr) during the years 2008 to 2014 reported to the Iranian Legal Medicine Organization. For data collection, legal medicine standard form was used and the cases were classified by age, gender, suicide way and time (year). The incidence of death from suicide was calculated by age and sex. Statistical soft-ware stata12 was used to analyze data. The significance level has been considered to be 0.05.

Results: Overall, 1,601 suicide-related deaths were investigated throughout the country. The mean age was 70.36 ± 0.17 years. The incidence trend (per 100,000 people) of the elderly suicides in Iran indicates that successful suicides have been on the rise, rising from 3.7 in 2008 to 4.37 per 100,000 people in 2014.

Conclusions: It is necessary to identify and treat suicidal important predisposing factors of suicide such as psycho-social illnesses including depression and also implement prevention programs and policies for this fast-rising population age-group.

Suicide rates in Zhejiang Province, China, from 2006 to 2016: a population-based study

Background

We investigated the current temporal trends of suicide in Zhejiang, China, from 2006 to 2016 to determine possible health disparities in order to establish priorities for intervention.

Methods

We collected mortality surveillance data from 2006 to 2016 from the Zhejiang Chronic Disease Surveillance Information and Management System from the Zhejiang Provincial Centre for Disease Control and Prevention. We estimated region-specific and gender-specific suicide rates using joinpoint regression analyses to determine the average annual percentage change (AAPC) and its 95% CI.

Results

The crude suicide rate declined from 9.64 per 100 000 people in 2006 to 4.86 per 100 000 in 2016, and the age-adjusted suicide rate decreased from 9.74 per 100 000 in 2006 to 4.14 per 100 000 in 2016. During 2006–2013, rural males had the highest suicide rate, followed by rural females, urban males, and urban females, while after 2013, urban males suicide rates surpassed rural female suicide rates, and became the second highest suicide rate subgroup. The rate of suicide declined in all region-specific and/or gender-specific subgroups except among urban males between 20 and 34 years of age. Their age-adjusted suicide rate AAPC greatly increased to 28.39 starting in 2013 compared with an AAPC of −13.47 from 2006 to 2013.

Conclusions

The suicide rate among young urban males has been alarmingly increasing since 2013, and thus, researchers must develop targeted effective strategies to mitigate this escalating loss of life.

Chronic obstructive pulmonary disease as a risk factor for suicide: A systematic review and meta-analysis

BACKGROUND

Patients living with chronic obstructive pulmonary disease (COPD) commonly present several limitations in their daily activities, high depression rates, and low quality of life, which makes this population a risk group for suicide. This study aims to systematically assess the literature on the association between CPOD and the likelihood of suicide.

METHODS

The protocol was registered in PROSPERO (CRD42018096618). The Latin-American and Caribbean Health Sciences Literature (LILACS), PubMed, SciELO, Scopus, LIVIVO, Web of Science, and PsychNET databases were used as primary study sources. OpenThesis and OpenGrey were used to partially capture the "grey literature". A manual search was also performed through a systematized analysis of the references of eligible articles. The risk of bias among the studies included was assessed with the Joanna Briggs Institute Critical Appraisal Tools for Systematic Reviews. A random effects meta-analysis was performed to estimate the variation in odds ratio (OR) and 95% confidence intervals (95% CI).

RESULTS

The search provided 4762 results, from which only seven met the eligibility criteria and were ultimately included in the qualitative assessment of the review. The studies were published from 2002 to 2015. All studies presented low risk of bias. The total sample included 1390 suicide cases of COPD patients. The meta-analysis, which was based on five eligible case control studies, found that people with history of COPD are more likely to commit suicide (OR = 1.90; 95% CI = 1.27-2.48; p = 0.002).

CONCLUSION

COPD patients are 1.9 times more likely to commit suicide than people without COPD.

Elderly suicide in Eskisehir, Turkey

Old age should be examined separately from other stages of life in terms of ratio, method and motives for suicide. With some variation, epidemiological studies suggest suicides increase with age in virtually every society. This study examines demographic data (age, sex and marital status), and other factors related to 20-years (1997-2016) of completed elder suicides in Eskisehir, Turkey. The 74 cases of those 65 and over were evaluated with regard to method, tool and location of the suicide. Annual distributions illustrate gradual increases in this fatal self-harm over time. The vast majority of cases were male (74.3%), compared to female (25.6%). Elders in the 80-84 age range were most likely to kill themselves. Deaths were frequently caused by hanging, followed by other methods and took place in the home. Reasons associated with suicidal behavior included despair as a result of bereavement, mental illnesses, chronic physical conditions and living alone. The researchers cite potential prevention strategies through the use of early mental health treatment for elders, along with inclusion in social services and activities.
