Factors related to Chinese older adults' suicidal thoughts and attempts

Epidemiological features of suicidal ideation among the elderly in China based meta-analysis

BACKGROUND

Studies on the prevalence of suicidal ideation (SI) and its associated factors among the elderly in China show considerable variability. This meta-analysis aims to clarify the epidemiological features of SI in this population.

METHODS

We systematically searched English and Chinese databases for relevant literature up to September 15, 2022. The extracted data facilitated the calculation of prevalence and odds ratios (ORs) for factors associated with SI among China's elderly.

RESULTS

We analyzed 31 cross-sectional studies, comprising a total of 79,861 participants from over 20 provinces and municipalities. The pooled prevalence of SI was found to be 11.47% [95% confidence interval (CI): 7.82-15.71%]. Significant variations in prevalence were influenced by residence, physical health (including chronic diseases and daily living capabilities), mental health (depressive symptoms and life satisfaction), economic status, and time-specific assessment tools. Notably, the prevalence from 2011-2020 (15.59%, 95% CI: 9.08-23.44%) was almost double that of 2001-2010 (7.85%, 95% CI: 5.08-11.16%). The SI prevalence in the eastern region (8.06%, 95% CI 5.59-10.94%) was significantly lower than in the central and western regions (16.97%, 95% CI 12.04-22.53%). Fourteen factors exhibited a significant pooled OR greater than 1 (p < 0.05), and two factors had ORs less than 1 (p < 0.05), indicating notable association with SI among the elderly.

CONCLUSION

SI among China's elderly showed relatively high prevalence and considerable heterogeneity across different characteristics and associated factors. This underscores the need for targeted intervention strategies and standardized temporal assessments of SI to effectively address suicide risk in this population.

A systematic review of psychosocial protective factors against suicide and suicidality among older adults

BACKGROUND

Research on suicide rarely focuses on protective factors. The goal of this systematic review was to assess the evidence of the associations between protective factors and reduced suicidality among older adults.

METHOD

First, a scoping review was conducted to identify pertinent terms that refer to various protective factors against suicidality. A systematic review, following the PRISMA guidelines, was then conducted on a selection of 15 protective factors (e.g., perceived control, well-being and quality of life, life satisfaction, purpose-in-life, resilience, coping, religiosity, hope, self-regulation, sense of belonging, mattering, positive relationship, social support, social connectedness, and social participation), with separate searches performed on each factor in five databases. Empirical studies were eligible if participants were adults aged 60 years and over, and if the studies reported predictive statistical analysis.

RESULTS

A total of 70 studies were retained for the review. Suicidal ideation was the main outcome measure (91%). Significant associations were consistently observed between all protective factors and reduced suicidal ideations or behaviors, particularly for purpose-in-life, resilience, and positive relationships, indicating that these are solid components for suicide prevention. Using scales, instead of a single item, to measure protective factors (e.g. life satisfaction) was more efficient to capture the associations. On the other hand, results were similar whether studies used subjective (e.g., sense of belonging) or objective (e.g., social connectedness) measures.

CONCLUSION

Protective factors were inversely associated with suicidal ideation. Improving protective factors is essential for the development of late-life suicide prevention and interventions, instead of merely focusing on risk factors.

What do older people who have attempted suicide experience? Study protocol for a qualitative meta-synthesis among older adults, family caregivers and healthcare professionals

INTRODUCTION

Attempted suicide among older adults represents a significant mental health concern that has witnessed a rising incidence within this demographic in recent years. Research indicates that attempted suicide among the older population serves as a primary risk factor for completed suicide. Consequently, the objective of this study is to provide a comprehensive overview of the prevailing factors that influence suicide attempts among older adults, thereby offering evidence to guide healthcare professionals in designing targeted interventions.

METHODS AND ANALYSIS

This study will adhere to the Joanna Briggs Institute framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. We will synthesise qualitative studies using a comprehensive and inclusive bibliographic search strategy. The following databases will be searched: PubMed, Embase, Web of Science, CINAHL and the Cochrane Library. The quality of the articles will be assessed using the 10-item Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. At the same time, data extraction will be performed using the Qualitative Assessment and Review Instrument data extraction form proposed by the Joanna Briggs Institute for Evidence-Based Practice. The synthesis of findings will adhere to the principles and procedures of Thomas and Hardens' three-stage thematic synthesis approach.

ETHICS AND DISSEMINATION

Ethical approval will not be required for this study, as it solely encompasses data derived from previously published research. The findings will be disseminated through publication in a peer-reviewed journal. Moreover, the results will be presented at relevant academic conferences to guarantee that the study's outcomes reach pertinent stakeholders. This protocol is registered with the PROSPERO prospective database for systematic review.

The Association between Perceived Family Financial Stress and Adolescent Suicide Ideation: A Moderated Mediation Model

Nowadays, suicide (especially adolescents' suicide) has been an increasingly prominent social problem worldwide; suicide ideation, as an important predictor, has been the focus of relevant studies and practices. Against this background, the present study aimed to examine the association between perceived family financial stress and adolescents' suicidal ideation, as well as the potential roles of depression and parent-child attachment. A sample of 526 junior middle school students was recruited voluntarily to participate in this cross-sectional study, and the results indicated that the prevalence of suicidal ideation among junior high school students was 15.45%; perceived family financial stress was positively associated with suicidal ideation, and depression could significantly mediate this relation; parent-child attachment significantly moderated the mediating effect of depression (in particular, the relation between depression and suicidal ideation); specifically, this relation was stronger among adolescents with lower values of parent-child attachment. These findings could deepen our understanding of the influences of perceived family financial condition and the risky factors of adolescents' suicidal ideation, which could provide guidance for the prevention and intervention of adolescents' depression and suicidal ideation.

Hope and Suicidal Ideation Among Older Adults Living in the Rural Mid-Hills of Nepal

OBJECTIVES

The current study investigated whether hope and its two components (agency and pathways) weakened the relations between perceived burdensomeness, thwarted belongingness, and fearlessness about death and suicidal ideation among older adults living in rural Nepal.

METHODS

A community sample of 300 people aged from 60 to 90 years (Mage = 67.07, SDage = 6.23) who resided in the rural mid-hills of Nepal completed standardized measures.

RESULTS

Hope and agency moderated the relationship between perceived burdensomeness and suicidal ideation and pathways moderated the relationship between thwarted belongingness and suicidal ideation.

CONCLUSIONS

Hope, and particularly agency, may play a protective role in reducing suicidal ideation among older Nepali adults living in rural areas who experience perceived burdensomeness. In contrast, pathways may be an additional risk factor for older adults experiencing unmet belongingness needs. Research is required to understand fearlessness about death and suicidality among older Nepali adults.

CLINICAL IMPLICATIONS

Increasing hope and particularly agency may be associated with a reduction in suicidal ideation among older Nepali adults who experience feelings of being a burden. However, increasing pathways may be associated with an increase in suicidal ideation among those who experience unmet belongingness needs. Research is needed to understand how to accurately assess suicide risk among Nepali older adults.

Mental Health and Recreational Angling in UK Adult Males: A Cross-Sectional Study

Exposure to aquatic environments (i.e., blue spaces) can lead to improved mental health and well-being. One meaningful way to spend time in blue spaces is through recreational angling, although limited scientific literature exists on this topic. The present study aims to examine the relationship between recreational angling and mental health and well-being in a sample of UK adult male anglers. A cross-sectional online survey asked questions about demographic characteristics, participation in recreational angling, physical activity levels, diagnosis of psychiatric disorders, and mental health and well-being. Relationships between angling status (i.e., how often and how long participants angled for) and mental health variables were determined using regression models adjusted for age. In total, 1752 participants completed the survey. The regression models found that those who took part in angling more regularly had reduced odds of having depression (p < 0.001), schizophrenia (p = 0.001), suicidal thoughts (p < 0.001), and deliberately self-harming (p = 0.012), in addition to having a higher mental well-being and lower symptoms of depression and anxiety compared to those taking part in angling less frequently. In general, the findings suggest that encouraging frequent participation in recreational angling could be a dual method strategy for promoting relaxation and positive mental health, as well as encouraging increased levels of physical activity in those with mental health issues.

Living with dementia: Why I am thinking of 'death'

BACKGROUND AND AIMS

Dementia is recognized globally as a massive burden on public health and wider society. It is a major cause of disability and mortality amongst older people. China has the largest population of people with dementia worldwide, accounting for approximately 25% of the entire global population of people with dementia. The study investigated the perceived experiences of care giving and care receiving in China, with one area identified in the data concerning the extent to which the participants discussed death. The research also explored the meaning of living with dementia in modern China, where the economy, demography and culture are rapidly changing.

METHOD

The qualitative approach of interpretative phenomenological analysis was used for this study. Semi-structured interviews were used for data collection.

FINDING

The paper reports on one specific finding concerning death as a way out of the situation that participants found themselves in.

CONCLUSION

The study described and interpreted one of the specific issues, 'death', in the participants' narratives. This finding reflects how psychological and social factors, such as stress, social support, healthcare cost, caring burden and medical practice have created the participants' thoughts of 'wishing to die' and the reasons why they believe 'death is a way to reduce burden'. It calls for an understanding, supportive social environment and a reconsideration of a culturally and economically appropriate family-based care system.

"I thought that I had to be alive to repay my parents": Filial piety as a risk and protective factor for suicidal behavior in a qualitative study of Chinese women

Filial piety involves the Confucian view that children always have a duty to be obedient and to provide care for their parents. Filial piety has been described as both a risk and a protective factor in depression and suicide. This qualitative study aimed to explore the role of filial piety in the suicidal behavior of Chinese women. Qualitative interviews were conducted with Chinese women with a history of suicidal behavior living in the Beijing area (n = 29). Filial piety data were extracted and analyzed in accordance with constructivist grounded theory. The women described five specific family and filial piety factors and how they influenced their ability to fulfill family role obligations, which was described as a nexus connecting these factors to depression, suicidal behavior, and recovery. The five factors were: 1) rigidity of parental filial expectations, 2) perception of family relationships as positive/supportive or negative/harsh, 3) whether filial piety is of high or low personal value in the woman's life, 4) any experiences of rebellion leading to punitive consequences, and 5) how much filial piety she receives from her children. These factors could inform suicide risk assessments in this population. They can be harnessed as part of recovery and protect against future suicidal behavior.

Suicide by Opioid: Exploring the Intentionality of the Act

Opioid toxicity can result in life-threatening respiratory depression. Opioid-overdose mortality in the United States is high and increasing, but it is difficult to determine what proportion of those deaths might actually be suicides. The exact number of Americans who died of an opioid overdose but whose deaths might be classified as suicide remains unknown. It is important to differentiate between those who take opioids with the deliberate and unequivocal objective of committing suicide, that is, those with active intent, from those with passive intent. The passive-intent group understands the risks of opioid consumption and takes dangerous amounts, but with a more ambiguous attitude toward suicide. Thus, among decedents of opioid overdose, a large population dies by accident, whereas a small population dies intending to commit suicide; but between them exists a sub-population with equivocal intentions, waxing and waning between their desire to live and the carelessness about death. There may be a passive as well as active intent to commit suicide, but less is known about the passive motivation. It is important for public health efforts aimed at reducing both suicides and opioid-use disorder to better understand the range of motivations behind opioid-related suicides and how to combat them.

Own health, spousal health and transitions in loneliness among middle-aged and older adults in China

This study examines the effects of own and spousal health on transitions in loneliness over time among married middle-aged and older adults in China, and explores the possible gender differences in these effects using data from the three waves of the China Health and Retirement Longitudinal Study (2011–2015). The sample includes 6,422 men and 6,391 women who were married and aged 45 and older at the baseline survey. Middle-aged and older adults with poorer physical and emotional health statuses are more likely to transition into and less likely to transition out of loneliness in a two-year period. Spouse's emotional health also affects both types of transition in loneliness and spouse's functional limitation affects transition into loneliness through spouse's emotional health. In addition, for married men, their own functional limitation is significantly associated with their transitions into and out of loneliness. For married women, their spouse's functional limitation is significantly associated with their transition into loneliness and this is mainly through its association with spouse's emotional health. Also, for married women, their spouse's emotional health is significantly associated with their transition out of loneliness. Social interventions to reduce feelings of loneliness need to take a couple approach and consider both spouses’ health problems and how they may affect their daily activities and their interactions with each other and with others.

Understanding the Reasons for Suicide Among Older Adults in Rural China Using In-Depth Interviews

Background: Suicide is a complex public health problem. Suicide rates are higher in rural areas than in urban areas and among older adults than any other age group in China. Aims: This study aimed to acquire a comprehensive understanding of rural older adults' reasons for suicide through qualitative exploration and to provide additional insights for suicide prevention work. Method: In-depth interviews were conducted with people familiar with older adults who had died by suicide ("informants"). The data were analyzed using a thematic approach. Results: Data were available for 242 people who died by suicide. Informants identified two or more reasons for suicide among most people who had died. Physical illness, psychological distress, and interpersonal conflicts were the most common reasons. The rate of mental disorders as diagnosed by psychiatrists was higher than that reported by the informants. Limitations: Information bias is inevitable because of the use of proxy informants. Conclusion: The reasons for suicide are complex and diverse, and research on suicide should focus more on the mechanisms of interaction between reasons. Greater attention should be paid to physical and mental health as well as to improving interpersonal and problem-solving skills for older adults in China.

Factors Influencing Suicidal Ideation and Attempts among Older Korean Adults: Focusing on Age Discrimination and Neglect

This study was conducted to identify factors influencing the development of suicidal ideation and the transition from suicidal ideation to attempts by focusing on experiences of age discrimination and neglect among older Korean adults. This study analyzed data from 10,042 older adults from the 2017 National Survey of Older Koreans using national representative samples. Multiple logistic analyses were used to identify factors influencing the development of suicidal ideation and transition from suicidal ideation to attempts. While younger age, higher educational attainment, living alone, number of chronic diseases, depressive symptoms, social isolation, social support, experience of neglect, and age discrimination influenced the development of suicidal ideation, all of these did not influence the transition from ideation to attempts. Factors influencing this transition included male gender, less educational attainment, and experience of age discrimination. Thus, social efforts to reduce age discrimination are necessary to prevent suicide attempts among Korean older adults.

Performance of an Abbreviated Lubben Social Network Scale (LSNS-6) among Three Ethnic Groups of Older Asian Americans

BACKGROUND AND OBJECTIVES

The present study examined the measurement quality and performance of an abbreviated Lubben Social Network Scale (LSNS-6) in three ethnic groups (Chinese, Koreans, Vietnamese) of older Asian Americans, addressing both within- and cross-group validations.

RESEARCH DESIGN AND METHODS

We selected 605 participants aged 50 or above (242 Chinese, 150 Koreans, 213 Vietnamese) from the 2015 Asian American Quality of Life (AAQoL) survey, conducted with self-identified Asian Americans aged 18 or above living in central Texas. We analyzed LSNS-6 data on measurement qualities (internal consistency and corrected item-total correlation), dimensionality (exploratory and confirmatory factor analyses), and correlations with other indicators.

RESULTS

LSNS-6 showed very good internal consistency in each ethnic group, and the two-factor structure of family and friends were invariant across the groups. The items on friends demonstrated greater homogeneity than those on family and emerged as a first factor. Both subscale and total scores of LSNS-6 were associated in expected directions with the social and health indicators considered.

DISCUSSION AND IMPLICATIONS

The findings confirm the measurement qualities of LSNS-6 within each group and provide support for measurement invariance across the groups. While the observed difference in family and friend networks warrants further investigation, LSNS-6 serves as a viable option for the assessment of social networks. When using LSNS-6 with older Asian Americans, it is highly recommended to use the family/friend subscales in consideration of cultural and immigration contexts.

Filial expectation among Chinese immigrants in the United States of America: a cohort comparison

Relying on two unique data-sets on Chinese older immigrants (N = 3,157) and younger immigrants with ageing parents (N = 469) in Chicago, this study compared the level of filial expectation among the two groups and examined the predictors and mental health implications of having high filial expectation among each group. Results of t-tests, logistic regression and negative binominal analyses showed that, regardless of socio-demographic variables, acculturation, physical health and family relations, Chinese adult children had higher filial expectations on themselves than older immigrants' filial expectation on the younger generation. Chinese older immigrants who had less education, lower levels of acculturation, poorer health and closer relationships with children reported higher filial expectation. In the cohort of younger immigrants, high filial expectation was associated with lower income, better health and closer relations with their parents. In addition, having high filial expectation was associated with lower levels of depression and anxiety among the older immigrants, but not among the younger cohort. The results indicated that, whereas Chinese older immigrants seemed to adapt their filial expectation in the new society, the younger cohort still strongly adhere to this traditional family norm. Maintaining strong filial expectation might be a protective factor for older immigrants' mental health. Practice and policy implications of these findings are discussed in the paper.

Measuring character strengths as possible protective factors against suicidal ideation in older Chinese adults: a cross-sectional study

BACKGROUND

Suicide is a global issue among the elderly. The number of older people committing suicide is proliferating, and the elderly suicide rate is the highest among all age groups in China. A better understanding of the possible protective factors against suicidal ideation is necessary to facilitate prevention and intervention efforts. The objectives of the present study are threefold. First, this study aims to examine the psychometric properties of the three-dimensional inventory of character strengths (TICS) with a sample of older adults. Second, this study intends to investigate correlations among suicide ideation, wellbeing, and character strengths. Third, the study seeks to explore the possible protective roles of the three character strengths and wellbeing in explaining suicidal ideation among older adults.

METHODS

A cross-sectional study comprising 308 older adults aged at least 50 years old from nursing homes was conducted. Four questionnaires, namely, the TICS, the Geriatric Suicide Ideation Scale-10 items, the Brief Inventory of Thriving, and the Satisfaction with Life Scale, were used. Exploratory structural equation modeling, intraclass correlation coefficients, partial correlations, and sets of hierarchical regressions were adopted to estimate and report the results.

RESULTS

TICS could be used to assess the character strengths (i.e., caring, inquisitiveness, and self-control) among older adults with an acceptable goodness-of-fit (chi square = 157.30, df = 63, p < 0.001, CFI = 0.94, TLI = 0.90, RMSEA = 0.07, 90% CI = [0.06, 0.08]). Wellbeing and character strengths exhibited a negative association with suicidal ideation among older adults. Moreover, character strengths showed an independently cross-sectional relationship with suicidal ideation, explaining 65.1% of the variance of suicidal ideation after controlling for the wellbeing and demographics.

CONCLUSION

This study indicated that character strengths were associated with low levels of suicidal ideation. Therefore, the protective factors against suicidal ideation among older adults should be given additional attention.

Suicidal thought in southern Brazil: Who are the most susceptible?

BACKGROUND

Suicide is one of the leading causes of death among adolescents and young adults worldwide. However, risk factors for suicidal thoughts might change across cultures and contexts. We aimed to assess the prevalence and associated factors of suicidal thought among adults in a southern Brazilian city.

METHODS

This population-based cross-sectional study used a multistage sampling procedure to evaluated individuals with 18 years or more, living in a southern city in Brazil. We collected suicidal thought using a question from the Patient Health Questionnaire-9. In addition, we collected information on sociodemographic, behavioral, and health variables, through a questionnaire using standardized and validated instruments. We calculated prevalence ratios (PR) using Poisson Regression models with robust adjustment of the variance.

RESULTS

We collected information from 1295 individuals, 6.6% were positive for suicidal thought. In multivariate analysis, factors independently associated with suicidal thoughts included: being a woman, poor, reporting current tobacco use, having household food insecurity, having three or more morbidities, being in the upper tertile of the stress scores, having had a depression diagnostic in the last year and sadness.

LIMITATIONS

We cannot say that the associations found are causal. Suicidal thoughts were assessed from a single question.

CONCLUSION

Suicidal thought is a prevalent condition, most likely associated with being a woman, having worst socioeconomic conditions, a poorer health, a higher stress, using tobacco and having depression and/or sadness.

Engagement in physical activity, suicidal thoughts and suicide attempts among older people in five developing countries

BACKGROUND

Suicide causes rising economic costs and public health risks for communities in the worldwide. Physical activity (PA) is considered a potentially feasible approach to reduce risk of suicide with low cost and high accessibility, and therefore attracting increasing attention. However, current literature on the association between PA and suicidal behavior amongst elderly people in low- and middle-income countries (LMICs) are scarce. Therefore, in this study we aimed to examine the relationship between suicidal thoughts (ST) and suicidal attempts (SA) with PA among elderly people in five LMICs.

METHODS

Cross-sectional data were collected from WHO's Study of Global Ageing and Adult Health (SAGE) with 2,861 participants aged 50 years or above. Variables included: self-reported occurrence of ST and SA during past 12 months and four types of PA (vigorous physical activity (VPA), moderate physical activity (MPA), walking/bike riding, moderate leisure time physical activity (MLPA)).

RESULTS

The overall prevalence of taking >75 min of VPA/week, >150 min/week, MLPA and walking/bike riding were, respectively, 85.4% (95% CI [81.3-88.7]), 61.6% (95% CI [52.9-69.6]), 9.6% (95% CI [7.2-12.6]) and 75.1% (95% CI [68.7-80.6]). Respectively, 31.0% (95% CI [24.3-38.7]) and 5.5% (95% CI [3.9-7.5]) of the respondents reported having morbid thoughts and SA during last 12 months. In adjusted multivariable regression analysis, not engaging in PA revealed positive association with higher odds of having morbid thoughts and SA, however, with varying degrees for different types of PA among men and women and across countries. The adjusted odds ratio among elderly who encountered ST increased significantly with PA levels (1.265 in male and 1.509 in female with VPA, 1.292 in male and 1.449 in female with MPA, 1.669 in female with LMPA and 3.039 in women with walk/bike); similarly, with SA (1.526, 1.532, 1.474 and 1.392 in women with VPA, MPA, LMPA and Walk/bike, respectively). The degree of adjusted odds ratio varied between genders and among countries.

CONCLUSION

Although the data were cross-sectional, and no linear dose-response relationship was observed between PA and morbid thought and suicide ideation, the findings provide important indications of potential harmful effects of no/inadequate PA on psychological morbidities among older individuals. Promoting adequate PA among older individuals through community-based suicide prevention programs can potentially contribute to reduction in the burden of PA in LMICs.

Addressing Loneliness in Complex PTSD

Loneliness impacts both physical and psychological health and is associated with increases of all-cause mortality and suicidal behavior. Because loneliness may result from a variety of developmental, interpersonal, and intrapersonal factors, distinguishing its components, origins, and sustaining factors as it manifests in various psychopathological states are important steps in formulating interventions to alleviate these conditions. To date, loneliness has not been widely studied in relation to complex posttraumatic stress disorder (PTSD), which is newly delineated in the International Classification of Diseases, characterized by PTSD symptoms in the context of significant early trauma, as well as "disturbances in self-organization" marked by affective dysregulation, negative self-concept, and disturbances in relationships. In this article, illustrating with case material, we suggest that loneliness plays a major role in the development of complex PTSD and in the preservation of its symptoms. Consequently, therapies for complex PTSD should include interventions that address loneliness.

Religious affiliation and major depressive episode in older adults: a cross-sectional study in six low- and middle- income countries

Background

The relationship of religious affiliation and mental health is complex, and being part of a minority religious group could have negative effects on mental health. In this study, we assessed the association between religious affiliation and major depressive episode (MDE) in older adults (> = 60 years) from China, Ghana, India, Mexico, Russia and South Africa.

Methods

We conducted a secondary analysis of data from the Study on global Ageing and adult health (SAGE), with six nationally-representative community-based samples (n = 21,410). Religious affiliation was self-reported by participants, and we defined MDE based on ICD-10 classification. We estimated the association of MDE with religious affiliation versus no religious affiliation, and minority versus majority affiliation.

Results

We observed no association between having a religious affiliation (vs. no affiliation) and the odds of MDE in older adults. In most cases minorities had higher odds of MDE as compared with the majority religion, but the associations were only significant for Muslims in Ghana and for Muslims, Hindus and Other in South Africa.

Conclusions

While the results were significant only for two countries, we observed higher odds of MDE among minorities in most of them. Older adults who are members of religious minorities might be at risk for mental health problems, and there is a need for public health interventions aimed at them.

Epidemiology of suicidal feelings in an ageing Swedish population: from old to very old age in the Gothenburg H70 Birth Cohort Studies

AIMS

The first aim of this study was to provide prevalence suicidal feelings over time (past week, past month, past year and lifetime) in a population-based sample of old to very old adults without dementia. Does prevalence change with rising age? The second aim was to examine the fluctuation of suicidal feelings over time. How does this coincide with depression status?

METHODS

Data were derived from the Gothenburg H70 Birth Cohort Studies (the H70 studies) which are multidisciplinary longitudinal studies on ageing. A representative sample of adults in Gothenburg, Sweden with birth years 1901-1944 were invited to take part in a longitudinal health study on ageing and participated at one or more occasions during 1986-2014. The sample consisted of 6668 observations originating from 3972 participants without dementia between the ages of 70 and 108, including 1604 participants with multiple examination times. Suicidal feelings were examined during a psychiatric interview using the Paykel questions (life not worth living, death wishes, thoughts of taking own life, seriously considered taking life, attempted suicide).

RESULTS

Prevalence figures for suicidal feelings of any severity were as follows: past week 4.8%, past month 6.7%, past year 11.2% and lifetime 25.2%. Prevalence rates increased with age in the total group and in women but not in men. Suicidal feelings were common in participants with concurrent major or minor depression, but over a third of the participants who reported suicidal feelings did not fulfil criteria for these diagnoses nor did they present elevated mean depressive symptom scores. The majority of participants consistently reported no experience of suicidal feelings over multiple examination times, but fluctuation was more common in women compared with men.

CONCLUSION

Suicidal feelings in late-life are uncommon in individuals without depression indicating that such behaviour is not a widespread, normative phenomenon. However, such feelings may occur outside the context of depression.

Life weariness and suicidal thoughts in late life: a national study in Sweden

OBJECTIVES

This study aimed at investigating the point prevalence of life weariness and suicidal thoughts and their relationship with socio-demographic characteristics in a population of older adults in Sweden.

METHOD

Data from 7913 individuals aged 60 years and older were drawn from the Swedish National Study on Aging and Care, a collaborative study in Sweden. Life weariness and suicidal thoughts were measured by one item derived from the Montgomery-Åsberg Depression Rating Scale. A multinomial regression model was used to investigate the relationships of socio-demographic characteristics with life weariness and suicidal thoughts.

RESULTS

Living in urban and semi-urban areas, being of advanced age, being divorced and having lower educational levels were related to life weariness. Living in a residential care facility, being widowed or unmarried, being born in a non-Nordic European country and experiencing financial difficulties were related to both life weariness and suicidal thoughts. Sex was found to be unrelated to either life weariness or suicidal thoughts.

CONCLUSION

This study found that several socio-demographic variables were associated with life weariness and suicidal thoughts among older adults. Specific attention to older individuals with these characteristics may be warranted as they might be more vulnerable to life weariness and suicidal thoughts.

Validation of an abbreviated version of the Lubben Social Network Scale ("LSNS-6") and its associations with suicidality among older adults in China

OBJECTIVE

This present study aims to estimate the structural validity, internal consistency reliability of the LSNS-6 and examine the associations between the LSNS-6 and suicidal outcomes among mainland Chinese older adults.

METHODS

This validation study used a big representative sample (N = 2819) of older adults in Beijing from the Sample Survey on Aged Population in Urban/Rural China. Confirmatory factor analyses (CFA) were applied to examine the factor structures of the Chinese version of LSNS-6. Internal consistency reliability of the LSNS-6 was examined by Cronbach's alpha coefficient and the corrected item-total correlation. Logistic regression analyses were used to explore the associations between the LSNS-6 and late-life death wishes, suicidal ideation in mainland Chinese.

FINDINGS

This present study showed good internal consistency and consistent factor structure of the LSNS-6 as well as its subscales. The present data demonstrated the LSNS-6 could be a useful tool for assessing social networks among older mainland Chinese. Interestingly, among the mainland Chinese, late-life suicidality was highly associated with the LSNS-6 family subscale, rather than the friends subscale.

CONCLUSION

The LSNS-6 could be a useful tool for assessing social networks among older mainland Chinese. In addition, suggestion is made to improve social networks, especially in family bonds and support, as a promising strategy in reducing late-life suicide risks in mainland China.

Intergenerational relationships and the trajectory of depressive symptoms among older Chinese adults in rural migrant families

OBJECTIVES

This study examined the trajectory patterns of depressive symptoms of older rural Chinese adults in migrant families and the role of intergenerational relationships in predicting trajectory class memberships.

METHOD

Data were derived from the 2001, 2003, 2006, and 2009 waves of a longitudinal survey titled The Well-being of Older People in Anhui Province. The sample featured 486 respondents who had at least one migrant adult children at all four waves. Growth mixture modeling was used to investigate the trajectory classifications of depressive symptoms from 2001 to 2009 and antecedents in differentiating among class memberships.

RESULTS

The findings suggested a two-class model to interpret depressive symptom trajectory patterns: persistently high symptoms and low but increasing symptoms. Older adults who had better intergenerational relationships at baseline were more likely to have low but increasing depressive symptoms after controlling for other covariates.

DISCUSSION

The findings suggest that intergenerational relationships have long-term impacts on depressive symptom trajectory classes. Policy and intervention implications are discussed.

Loneliness, common mental disorders and suicidal behavior: Findings from a general population survey

BACKGROUND

Loneliness has been linked to an increased risk of engaging in suicidal behavior. To date, however, there has been comparatively little research on this in the general adult population, or on the role of common mental disorders (CMDs) in this association. The current study examined these associations using nationally representative data from England.

METHODS

Data came from the Adult Psychiatric Morbidity Survey 2007. Information was obtained from 7403 household residents aged ≥16 years on perceived loneliness and lifetime and past 12-month suicide ideation and attempts. The Clinical Interview Schedule Revised (CIS-R) was used to assess six forms of CMD. Logistic regression analysis was used to examine these associations.

RESULTS

Loneliness was associated with suicidal behavior. Although adjusting for CMDs attenuated associations, higher levels of loneliness were still significantly associated with suicidal ideation and suicide attempts with odds ratios (OR) for those in the most severe loneliness category ranging from 3.45 (lifetime suicide attempt) to 17.37 (past 12-month suicide attempt). Further analyses showed that ORs for suicidal behavior were similar for individuals who were lonely without CMDs, and for those respondents with CMDs who were not lonely. Lonely individuals with CMDs had especially elevated odds for suicidal ideation.

LIMITATIONS

This study used cross-sectional data and a single-item measure to obtain information on loneliness.

CONCLUSION

Loneliness is associated with suicidal behavior in the general adult population. This highlights the importance of efforts to reduce loneliness in order to mitigate its harmful effects on health and well-being.
