Mortality after death of spouse in relation to duration of bereavement in Finland

Suicide After Partner's Death in the Elderly Population: Results From a Nationwide Cohort Study in Italy

OBJECTIVE

This study aims to investigate the effect of partner loss on suicide mortality for surviving partners in the elderly Italian population and to explore differences according to sex and time elapsed since the loss.

DESIGN

This was a historical cohort study.

SETTING

All Italian residents registered by the 15th Italian Population Census (9 October 2011) were linked to emigration records and death certificates for 2012-2017 to track migration, vital status, and cause of death.

PARTICIPANTS

5,068,414 individuals living as a couple, as registered in the census, and aged ≥69 years on January 1, 2012.

MEASUREMENTS

Mortality rate ratios (MRR) estimated through Poisson regression models were used to compare suicide mortality at age ≥75 years between subjects who experienced partner loss and those who did not.

RESULTS

Among people who experienced partner loss, there were 383 suicide deaths in men and 90 in women. Suicide mortality was higher in older men and women who experienced the loss compared to those who did not, and the impact of the spouse loss on mortality was stronger in men (age-adjusted MRR=2.83) than in women (1.41). Among men the excess risk was particularly high during the first year following the loss; in women, no substantial differences in the excess risk were observed over the follow-up period.

CONCLUSION

Study findings provide evidence of the sex differences in the impact of spouse loss based on data from a large national cohort and reinforce the need for monitoring suicide risk in recently widowed older people.

Bereavement and Grief Among Employees in an Arab University Setting: A Cross-Sectional Study

BACKGROUND

Several mental health outcomes develop following bereavement. Little research has examined bereavement in the workplace and the associated risk factors, particularly in Arab populations.

OBJECTIVES

The objectives of this cross-sectional study were to determine the sociodemographic characteristics of bereaved employees, measure the prevalence of their dysfunction, establish the type of closeness and conflict in their relationship with the deceased, determine the available resources to the bereaved, and determine the proportion of bereaved employees who needed help.

METHODS

A study was conducted on Arabian Gulf University employees (91) in Bahrain. The revised Two Track Bereavement Questionnaire (TTBQ3-CG11) was utilized to assess bereavement outcomes.

RESULTS

The response rate of the study was 28%. The composition of the study population was as follows: 51.6% males, 37.4% in the age range of 40-49 years, 86.8% married, 39.6% Bahraini, and 51.6% academicians. Over half of the participants had biopsychosocial dysfunction, 35.2% had active relational grief and trauma (ARGT), 36.3% had a conflict with the deceased, and half were close to the deceased. Total TTBQ3-CG11 scores showed that 28.6% of the bereaved had a low score (14-22), 61.5% medium (23-28), and 9.9% high (29 or more), with more females than males in the high category. The majority reported receiving adequate support from the administration and colleagues following their loss.

CONCLUSION

There is a need to establish bereavement policies and procedures at tertiary educational institutes. This study may inform future policies to advance bereavement services in the educational institutions of the region.

Widowhood and mortality risk in Taiwan: a population-based matched cohort study

BACKGROUND

Studying the causes of death among deceased spouses and surviving partners may provide insights into the underlying mechanisms of the association between widowhood and mortality. This study investigated the mortality risk of widowhood in Taiwan, examined the association of the cause of death between widowed individuals and their deceased spouses and explored potential modifying effects by age, gender and duration after widowhood.

METHODS

This matched cohort study utilized Taiwan's National Health Insurance claims database and National Death Registry. In total, 204 010 widowed men and 596 136 widowed women were identified with a mean follow-up period of 6.9 and 7.9 years, respectively, and 816 040 comparison men and 2 384 544 comparison women were selected.

RESULTS

Widowhood was associated with an increased mortality risk, with widowed men having a 1.32 increased risk and widowed women having a 1.27 increased risk. Age at spousal death and duration modified the associations after widowhood. The widowed individuals are more likely to die by the same cause as the deceased spouse if they died by suicide, accident, endocrine, gastrointestinal disorders or infection.

CONCLUSIONS

The study suggests that healthcare policies and interventions should be developed to improve widowed individuals' health and overall welfare.

Pathways into single motherhood, re-partnering, and trajectories of antidepressant medication purchases

Single motherhood is known to be distressing, and to be associated with poor mental health. However, less is known about the pathways into and out of single motherhood, or about the mental health trajectories of single mothers. We used total population registry data on Finnish women who experienced the life events of separation (616,762), widowhood (43,355), or child birth (515,756) during the 1995-2018 period while between the ages of 15-64. Single mothers were compared with women who experienced the same life event, but without becoming a single mother. The results for women who separated showed that among single mothers, there was a substantial increase in antidepressant use at the time of separation, and only a moderate decline after separation. Among women who experienced widowhood, those who had underage children initially had lower antidepressant use than women without children, but this gap narrowed in the post-widowhood period. In addition, single women experienced more unfavorable mental health trajectories than partnered women around the time they gave birth. Re-partnering was associated with more favorable mental health among all groups of single mothers. Given the growing prevalence of single-parent households, our results underscore the need for context-specific interventions to support single mothers' mental health.

Serious Mental Illness Exacerbation Post-Bereavement: A Population-Based Study of Partners and Adult Children

Purpose

The death of a close family member is commonly accompanied by intense grief, stress, and loss of social support. We hypothesized that recent bereavement would be associated with an increase in symptom exacerbations among adults with serious mental illness (SMI) whose partners or parents had died.

Patients and Methods

Adults whose partners and parents had died in Denmark between January 1, 2010, and June 30, 2016, were identified using linked population-based registries. History of SMI was defined as having a diagnosis of schizophrenia and schizoaffective disorders, major depression, and bipolar disorder in the five years preceding their family member's death in the Danish Psychiatric Central Research Register using International Classification of Diseases-10 codes. The odds of SMI exacerbation (ie, attempt or completion of suicide or psychiatric hospitalization) among partners and children in the first two years after death in 3-month intervals were estimated with generalized estimating equations.

Results

12.8% of partners and 15.0% of adult children with a history of SMI experienced any SMI exacerbation two years after bereavement. Among bereaved partners, older age (80+ years) was associated with a lower risk of experiencing an SMI exacerbation compared with partners aged 18-49 years (OR_adj=0.29, [0.18-0.45]). Partners with a history of SMI had significantly increased odds of SMI exacerbations three months after their partners' death compared to prior to their partners' death (ORadj = 1.43, [1.13-1.81]). There was no evidence that adult children with SMI experience increased SMI exacerbations after the death of their parents compared to prior to death.

Conclusion

Adults with a history of SMI whose partners had died are at increased risk for an SMI exacerbation post bereavement. Additional bereavement resources and support should be provided to those with a history of SMI, especially in the period immediately after death.

Adverse outcomes after partner bereavement in people with reduced kidney function: Parallel cohort studies in England and Denmark

OBJECTIVES

To investigate whether partner bereavement is associated with adverse cardiovascular and kidney-related events in people with reduced kidney function.

DESIGN

Two parallel matched cohort studies using linked routinely collected health data.

SETTING

England (general practices and hospitals using linked Clinical Practice Research Datalink, Hospital Episode Statistics, and Office of National Statistics) and Denmark (hospitals and community pharmacies using the Danish National Patient, Prescription and Education Registries and the Civil Registration System).

PARTICIPANTS

Bereaved people with reduced kidney function (estimated glomerular filtration rate (eGFR) <60mL/min/1.73m2 (England) or hospital-coded chronic kidney disease (Denmark)) and non-bereaved people with reduced kidney function similarly defined, matched on age, sex, general practice (England), and county of residence (Denmark) and followed-up from the bereavement date of the exposed person.

MAIN OUTCOME MEASURES

Cardiovascular disease (CVD) or acute kidney injury (AKI) hospitalization, or death.

RESULTS

In people with reduced kidney function, we identified 19,820 (England) and 5,408 (Denmark) bereaved individuals and matched them with 134,828 (England) and 35,741 (Denmark) non-bereaved individuals. Among the bereaved, the rates of hospitalizations (per 1000 person-years) with CVD were 31.7 (95%-CI: 30.5-32.9) in England and 78.8 (95%-CI: 74.9-82.9) in Denmark; the rates of hospitalizations with AKI were 13.2 (95%-CI: 12.5-14.0) in England and 11.2 (95%-CI: 9.9-12.7) in Denmark; and the rates of death were 70.2 (95%-CI: 68.5-72.0) in England and 126.4 (95%-CI: 121.8-131.1) in Denmark. After adjusting for confounders, we found increased rates of CVD (England, HR 1.06 [95%-CI: 1.01-1.12]; Denmark, HR 1.10 [95%-CI: 1.04-1.17]), of AKI (England, HR 1.20 [95%-CI: 1.10-1.31]; Denmark HR 1.36 [95%-CI: 1.17-1.58]), and of death (England, HR 1.10 [95%-CI: 1.05-1.14]; Denmark HR 1.20 [95%-CI: 1.15-1.25]) in bereaved compared with non-bereaved people.

CONCLUSIONS

Partner bereavement is associated with an increased rate of CVD and AKI hospitalization, and death in people with reduced kidney function. Additional supportive care for this at-risk population may help prevent serious adverse events.

The impact of income definitions on mortality inequalities

Income is a strong predictor of adult mortality. Measuring income is not as simple as it may sound. It can be conceptualized at the individual or the household level, with the former better reflecting an individual's earning ability, and the latter better capturing living standards. Furthermore, respondents are often grouped into income categories based on their positions in the income distribution, and this operationalization can be done on the basis of age-specific or total population income distributions. In this study, we look at how four combinations of different conceptualizations (individual vs. household) and operationalizations (age-specific vs. total population) of income can affect mortality inequality estimates. Using Finnish registry data, we constructed period life tables for ages 25+ from 1996 to 2017 by gender and for four income definitions. The results indicated that the slope index of inequality for life expectancy varied by 1.1-5.7 years between income definitions, with larger differences observed for women than for men. The overall age patterns of relative index of inequality for mortality rates yielded by the four definitions were similar, but the levels differed. The period trends across income definitions were consistent for men, but not for women. We conclude that researchers should pay particular attention to the choice of the income definitions when analyzing the association between income and mortality, and when comparing the magnitude of inequality across studies and over time.

Biological mechanisms underlying widowhood's health consequences: Does diet play a role?

The loss of a spouse is a highly stressful event that puts older adults at increased risk for morbidity and mortality. The risk is highest in the first year to 18 months post-loss; nevertheless, widow(er)s, in general, are at heightened risk of cardiovascular disease (CVD) related morbidity and mortality, and to a lesser extent, non-CVD related morbidity and mortality. The primary goal of this article is to argue for a perspective that considers diet and emotion-induced autonomic, neuroendocrine, and immune dysregulation, in unison, to understand the mechanisms underlying morbidity and mortality in early widowhood. Toward this end, we first summarize our previously published work, as well as work from other investigatory teams, showing that compared with those who were not bereaved, widow(er)s have higher levels of pro-inflammatory cytokine production and more dysregulated autonomic and neuroendocrine activity than non-widow(er)s, independent of health behaviors such as diet. We highlight that a major gap in our current understanding of the biobehavioral mechanisms that underlie the widowhood effect is the role of diet and hypothesize that the adverse health impact of grief and associated negative emotions and diet may be more than additive. Therefore, we propose that diet may be a pathway by which widow(er)s are at higher CVD risk requiring further investigation.

•

Losing a spouse is highly stressful event; it increases one’s risk for morbidity and mortality, especially within the first 18 months post-loss.

•

Widow(er)s are at risk of cardiovascular disease (CVD)- and non-CVD related morbidity and mortality.

•

The role of diet is a major gap in our understanding of the biobehavioral mechanisms that underlie the widowhood effect.

•

Diet clearly impacts CVD, and widow(er)s' eating habits are altered for at least the first two years post-loss.

•

The adverse health impact of stress and diet may be more than additive; it may be synergistic.

Immigration Background and the Widowhood Effect on Mortality

Objectives

Widowhood is a stressful life event with one of the most profound negative effects on health and longevity. Immigrant populations are growing and aging throughout Western nations, and marginalization and cultural differences may make some immigrants especially vulnerable to the stressors of widowhood. However, studies have yet to systematically explore whether the widowhood effect differs between immigrant and native-born individuals.

Methods

Using Danish population register data from 1980 to 2014, this study assesses whether the relationship between widowhood and mortality differs between immigrants from 10 countries and native-born Danes aged 50 and older at 0–2, 3–5, and 6 and more years post-widowhood.

Results

We find that immigrant men are at higher risk of dying in the first 2 years after experiencing widowhood than Danish-born men, but these mortality differences dissipate over longer periods. Immigrant women have a higher risk of having died 3 and more years after a spouse’s death than Danish women. Patterns vary further by country of origin.

Discussion

The results suggest that some immigrants may suffer more from widowhood than native-born individuals, giving insight into how immigration background may influence the health effects of negative life events. They also underscore the potential vulnerabilities of aging immigrant populations to stressors encountered in older age.

The Effects of Marital Status, Fertility, and Bereavement on Adult Mortality in Polygamous and Monogamous Households: Evidence From the Utah Population Database

Although the associations among marital status, fertility, bereavement, and adult mortality have been widely studied, much less is known about these associations in polygamous households, which remain prevalent across much of the world. We use data from the Utah Population Database on 110,890 women and 106,979 men born up to 1900, with mortality follow-up into the twentieth century. We examine how the number of wife deaths affects male mortality in polygamous marriages, how sister wife deaths affect female mortality in polygamous marriages relative to the death of a husband, and how marriage order affects the mortality of women in polygamous marriages. We also examine how the number of children ever born and child deaths affect the mortality of men and women as well as variation across monogamous and polygamous unions. Our analyses of women show that the death of a husband and the death of a sister wife have similar effects on mortality. Marriage order does not play a role in the mortality of women in polygamous marriages. For men, the death of one wife in a polygamous marriage increases mortality to a lesser extent than it does for men in monogamous marriages. For polygamous men, losing additional wives has a dose-response effect. Both child deaths and lower fertility are associated with higher mortality. We consistently find that the presence of other kin in the household—whether a second wife, a sister wife, or children—mitigates the negative effects of bereavement.

Is impending or actual death of a spouse with dementia bad for mental health? Antidepressant use surrounding widowhood

Background

Previous studies have shown that the risk of death is elevated after the death of a spouse. Limited evidence is available on changes in mental health before and after bereavement among individuals whose spouse dies of dementia.

Methods

We analyzed changes in the 3-month prevalence of antidepressant use for 5 years before and 3 years after widowhood for individuals whose spouses died of either dementia or other causes. The study used data of 41 855 widowed individuals and repeated-measures logistic regression analyses. Antidepressant use was based on the prescription register of Finland in 1995–2007.

Results

Five years before widowhood, the 3-month prevalence for antidepressant use was 4% among widowing men and 6–7% among widowing women, regardless of whether the spouse died of dementia or other causes. Further changes in antidepressant use depended on a spouse’s cause of death. Women whose spouses died of dementia experienced large increase in antidepressant use starting from 3 to 4 years prior to widowhood, whereas other widows did not experience large increase until after widowhood. The trajectories for men were similar. Antidepressant use following the death of a spouse with dementia stayed at a new heightened level after widowhood.

Conclusions

The trajectories of antidepressant use indicate that the process of losing a spouse to dementia is bad for mental health, already a few years prior to widowhood. There are no clear improvements in mental health after the death of a spouse with dementia. Support services for individuals whose spouses’ dementia progresses are needed.

Increased risk for hip fracture after death of a spouse-further support for bereavement frailty?

Death of a spouse is associated with poorer physical and mental health. We followed all married individuals, born from 1902 to 1942, during the period from 1987 to 2002, and found that widows and widowers had higher risk for hip fracture, compared with still married women and men.

INTRODUCTION

Spousal bereavement can lead to poorer physical and mental health. We aimed to determine whether married women and men had an elevated risk of hip fracture after death of a spouse.

METHODS

In a retrospective cohort study, we followed all Swedish married individuals aged 60 to 100 years (n = 1,783,035), from 1987 to 2002. Data are presented as mean with 95% confidence interval (CI).

RESULTS

During the follow-up period, 21,305 hip fractures among widows and 6538 hip fractures among widowers were noted. The hazard ratio (HR) for hip fracture in widows compared with married women was 1.34 (95% CI 1.31 to 1.37) and for widowers compared with married men 1.32 (95% CI 1.29 to 1.35). The HR for hip fracture in the first 6 months after death of a spouse was in widows compared with married women 1.62 (95% CI 1.53 to 1.71) and in widowers compared with married men 1.84 (95% CI 1.68 to 2.03). The elevated risk was especially prominent in young widowers in the age range 60-69 years. During the first 6 months they showed a HR of 2.76 (95% CI 1.66 to 4.58) for a hip fractvure compared with age matched married men. Widows aged 60-69 years showed a HR of 1.59 (95% CI 1.26 to 1.99) compared with age matched married women.

CONCLUSION

Our observation of a higher hip fracture risk in both genders in connection with the death of a spouse indicates a possible effect of bereavement on frailty.

Perceptions of the Use of Alcohol and Drugs after Sudden Bereavement by Unnatural Causes: Analysis of Online Qualitative Data

Bereavement is associated with an increased risk of psychiatric morbidity and all-cause mortality, particularly in younger people and after unnatural deaths. Substance misuse is implicated but little research has investigated patterns of drug or alcohol use after bereavement. We used a national online survey to collect qualitative data describing whether and how substance use changes after sudden bereavement. We conducted thematic analysis of free-text responses to a question probing use of alcohol and drugs after the sudden unnatural (non-suicide) death of a family member or a close friend. We analysed data from 243 adults in British Higher Education Institutions aged 18–40, identifying two main themes describing post-bereavement alcohol or drug use: (1) sense of control over use of drugs or alcohol (loss of control versus self-discipline), (2) harnessing the specific effects of drugs or alcohol. Across themes we identified age patterning in relation to substance misuse as a form of rebellion among those bereaved in childhood, and gender patterning in relation to men using alcohol to help express their emotions. The limitations of our sampling mean that these findings may not be generalizable from highly-educated settings to young people in the general population. Our findings describe how some young bereaved adults use drugs and alcohol to help them cope with traumatic loss, and suggest how clinicians might respond to any difficulties controlling substance use.

Widowhood and mortality risk of older people in rural China: do gender and living arrangement make a difference?

Increased mortality after spousal bereavement has been observed in many populations. Few studies have investigated the widowhood effect in a traditional culture where the economy is underdeveloped. The reasons for the widowhood effect and its gender dynamic are not well understood. In this study, we assessed whether the widowhood-associated excess mortality exists and differs by gender and living arrangement in rural China. We used a six-wave panel of data derived from rural people over 60 years old in the Chaohu region of China. Cox regression analyses suggest that there was a positive effect of spousal loss on mortality for older rural Chinese and this effect was gender different. Our findings also suggest that living with adult children after spousal loss played a protective role in reducing the risk of older men's death, though it tended to increase older men's mortality risk in general.

The role of rumination in the guilt associated with bereavement according to cause of death

The purpose of this study was to analyse the role rumination plays in the relationship between cause of death and the guilt present during bereavement. The sample consisted of 90 people that had suffered a loss due to an expected or unexpected natural death, suicide or accident. The results suggest that rumination increases the levels of guilt felt by people that had suffered a loss due to suicide compared to those whose loss was due to an expected natural death. These findings contribute to a better understanding of the mechanisms with an influence on bereavement.

Frailty in Survival Analysis of Widowhood Mortality

Heterogeneity between individuals has attracted attention in the literature of survival analysis for several decades. Widowed individuals also differ; some are more frail than others and thereby have a higher risk of dying. The traditional hazard rate in a survival model is a measure of population risk and does not provide direct information on the unobservable individual risk. A frailty model is developed and applied on a large Norwegian data set of 452 788 widowed individuals. The model seemed to fit the data well, for both widowers and widows in all age groups. The random frailty term in the model is significant, meaning that widowed persons may have individual hazard rates.

Does the death of a child influence parental use of psychotropic medication? A follow-up register study from Finland

Background

Several studies have found that the loss of a child is associated with psychiatric health problems, yet few studies examined whether child loss influences psychotropic medication use. This study examined short- and long-term use of psychotropic medication, both before and after the death of a child, and its potential effect modifiers.

Methodology/Principal findings

A random sample of 205,456 parents, including 902 bereaved parents, were selected from a Finnish total population registry. The analyses were based on linear regressions using generalised estimation equations (GEE) and adjusted for sociodemographic factors. Annual psychotropic use was defined as having purchased prescribed psychotropic medication between 1996 and2012. Bereaved parents were followed for four years prior to and up to four years after the death of their child. An increase in the use of antidepressants and anxiolytics was found in parents following their loss. The highest percentage of use was found around one year after bereavement, followed by a steady decrease although this remained higher than the level of use among non-bereaved four years after the death. Between 20–25% of bereaved mothers and 10–15% of bereaved fathers used antidepressants or anxiolytics one year after bereavement while the corresponding number in non-bereaved was 5–10%. An increase in psychotropic medication was also found several years before the disease-related loss of a child.

Conclusions/Significance

The use of psychotropic medication is markedly higher among parents after losing a child. Patterns of use leading up to and following the death of a child should be further examined in relation to clinical risk factors so as to identify at risk populations.

Consanguineous Marriage and the Psychopathology of Progeny: A Population-wide Data Linkage Study

IMPORTANCE

Approximately 1 in 10 children worldwide are born to consanguineous parents. The literature on consanguinity and mental health of progeny is scarce despite the fact that many of the factors associated with consanguineous unions are also associated with mental health.

OBJECTIVE

To investigate if children of consanguineous parents are at increased risk of common mood disorders or psychoses.

DESIGN, SETTING, AND PARTICIPANTS

This investigation was a retrospective population-wide cohort study of all individuals born in Northern Ireland between January 1, 1971, and December 31, 1986, derived from the Child Health System data set and linked to nationwide administrative data sources on prescription medication and death records. Data from the Child Health System data set identified all 447 452 births delivered to mothers residing in Northern Ireland between 1971 and 1986. The final data set comprised 363 960 individuals, alive and residing in Northern Ireland in 2014, with full data on all variables. The dates of analysis were June 1 to October 31, 2017.

MAIN OUTCOMES AND MEASURES

Degree of parental consanguinity was assessed from questions asked of the parents during routine health visitor house calls within 2 weeks of the child's birth. Potential mental ill health was estimated by receipt of psychotropic medication in 2010 to 2014. Ever or never use was used for the main analysis, with sensitivity analyses using a cutoff of at least 3 months' prescriptions. Receipt of antidepressant or anxiolytic medications was used as a proxy for common mood disorders, whereas receipt of antipsychotic medications was used as a proxy indicator of psychoses.

RESULTS

Of the 363 960 individuals (52.5% [191 102] male), 609 (0.2%) were born to consanguineous parents. After full adjustment for factors known to be associated with poor mental health, multilevel logistic regression models found that children of first-cousin consanguineous parents were more than 3 times as likely to be in receipt of antidepressant or anxiolytic medications (odds ratio, 3.01; 95% CI, 1.24-7.31) and more than twice as likely to be in receipt of antipsychotic medication (odds ratio, 2.13; 95% CI, 1.29-3.51) compared with children of nonrelated parents.

CONCLUSIONS AND RELEVANCE

A child of consanguineous parents is at increased risk of common mood disorders and psychoses.

Occupational class and the changing patterns of hospitalization for affective and neurotic disorders: a nationwide register-based study of the Finnish working-age population, 1976-2010

PURPOSE

This study aimed to examine the long-term changes and socioeconomic disparities in hospitalization for affective and neurotic disorders among the Finnish working-age population from 1976 to 2010.

METHODS

Register-based study, consisting of a 5-year follow-up of 3,223,624 Finnish working-age (18-64-year old) individuals in seven consecutive cohorts. We calculated the hazard ratios of psychiatric hospitalization for different occupational classes using Cox regression models.

RESULTS

The risk of hospitalization for affective and neurotic disorders increased in all occupational classes after the economic recession in the 1990s, and then decreased in the 2000s. Before the 2000s, the risk was the highest among manual workers. In the 2000s the disparities between upper-level non-manual employees and other occupational classes increased. Hospitalization rates remained high among female manual workers and non-manual lower-level employees.

CONCLUSIONS

This study revealed important similarities and differences between occupational classes in terms of long-term changes in hospitalization for affective and neurotic disorders. The results suggest that the labor market changes and healthcare reforms during the 1990s and 2000s in Finland have been more beneficial for higher than for lower occupational classes.

Patient and Spousal Health and Outcomes in Heart Failure

BACKGROUND

A diagnosis of heart failure (HF) often requires a comprehensive lifestyle change to maintain disease stability. When patients with HF are married, the spouse frequently assumes the caregiving role. Our objectives were to describe the health of spouses of married patients with HF, and examine whether the health of a spouse impacts patient outcomes.

METHODS AND RESULTS

We identified 905 patients that were married at the time of incident HF diagnosis in Olmsted County, MN, from 2000 to 2012. Using Rochester Epidemiology Project resources, the patient and their spouse's comprehensive longitudinal health histories were linked. Spousal health at patient HF diagnosis was assessed by comorbidity burden, self-reported difficulty with activities of daily living and prior hospitalizations. The associations of spousal health with patient outcomes and patient death with spousal outcomes were examined using Cox and Andersen-Gill models. Spouses of patients with HF were elderly (mean age, 71 years), often had comorbid conditions, and 16% had difficulty with ≥1 activities of daily living. After adjustment for patient age, sex, and comorbidity, there were no independent associations of spousal health and patient risk of death or hospitalization after HF diagnosis. However, the risk of hospitalization (adjusted hazard ratio, 1.34; 95% confidence interval, 1.11-1.60; P=0.002) and death (hazard ratio, 2.10; 95% confidence interval, 1.60-2.75; P<0.001) increased in the surviving spouse after patient death.

CONCLUSIONS

We found no evidence that the health of a spouse impacts patient outcomes after HF diagnosis. However, after a patient with HF dies, their surviving spouse's risk of hospitalization and death increases.

Crisis or Chronic Strain?: Gender and Age Differences in Sickness Absence following Early Spousal Loss

This population-based study ( N = 908,468) examines the effects of spousal loss on being absent from work due to illness or injury (sickness absence) among employed individuals in Norway. Fixed-effects models capturing antecedent and short- and long-term effects of spousal loss over a 15-year period were estimated to explore gender and age differences in the impact of widowhood. The crisis model, the social-role model, and the life course perspective are discussed. Furthermore, the study calls into question whether parenthood explains the gendered age gradient of the widowhood effect. The results show that the theoretical relevance of the crisis and social-role models is best understood in dialogue with a gendered life course approach. The results show that the crisis response is especially high among young widowers, whereas the recovery period is markedly prolonged among young widows. Parenthood at the time of widowhood explains much of the age difference among widowers and widows.

Increased risk of death immediately after losing a spouse: Cause-specific mortality following widowhood in Norway

OBJECTIVE

This paper examines the short-term risk of cause-specific death following widowhood.

METHOD

We followed all individuals registered as married in Norway in 1975 for marital status and mortality until 2006. Widowed individuals were followed for mortality for 7years following widowhood. Causes of death were categorized into five cause-groups. Life tables were used in survival analyses.

RESULTS

Deaths among the widowed were most frequent in the week following widowhood. In this week and compared to married individuals, there were more deaths including those from malignant cancer in men (hazard ratio (HR) of 1.51; 95% CI: 1.12, 1.89), from external causes in men (HR=3.64; 95% CI: 2.01, 5.28), and from respiratory diseases (HR=2.18; 95% CI: 1.52, 2.84 in men and HR=3.18; 95% CI: 2.26, 4.09 in women). A majority of respiratory deaths were from pneumonia. Thereafter excess mortality among the widowed dropped gradually. Although these numbers stabilized, they were still elevated in year 7. Excess mortality was particularly high in the youngest age group considered (55-64years) and decreased with age, though more so in men than in women. Only a few more widowed individuals than expected died of a condition in the same cause-group as their spouses.

CONCLUSION

A novel finding was that excess deaths in the week following widowhood also were from cancer and respiratory diseases. Men in the youngest age group seemed most vulnerable. Prevention should be considered directly after the death of a spouse, and measures should be aimed at virtually all causes of death.

Mortality after the death of a spouse in Norway

BACKGROUND

Previous studies on mortality of widowed individuals have produced varying estimates of mortality after the death of a spouse. This variation is because of the various data types used and methodologies applied, as well as to the failure to account for sources of bias.

METHODS

We followed all married individuals in Norway (1,801,456 individuals) for 32 years, and information on marital status and death was collected for use in a new application of survival analysis in this field of research.

RESULTS

We compared mortality of widowed individuals with that of married individuals. Widowed men and women had hazard ratios of 1.34 (95% confidence interval 1.31, 1.36) and 1.29 (1.26, 1.31), respectively, for the first year after spousal death. For the same period, values were highest in ages 60-64 years with 1.78 (1.57, 1.98) in men and 1.50 (1.35, 1.65) in women. Values dropped gradually with age and more rapidly in men than women to a low for ages 85-89 years of 1.24 (1.19, 1.29) in men and 1.25 (1.20, 1.31) in women. The risk was much higher 1 to 7 days after spousal death (1.69 [1.49, 1.88] in men and 1.76 [1.56, 1.96] in women), then it dropped during the first year and from then on remained stable to year 10, which was the last year considered.

CONCLUSION

A considerable excess mortality risk was observed in widowed men and women from immediately after the loss of a spouse and for the next 10 years.

Living arrangements and marital status: a register-based study of survival of older adults in Belgium at the beginning of the 21st century

Being married reduces the mortality risk of older persons. More generally, living arrangements that include co-residence with a source of support and a close care-giver are associated with a lower mortality risk. We build a detailed typology of private and collective living arrangements, including marital status, and check its association with mortality risks, controlling for health status. Using administrative data from the population register, we identify the living arrangement of all individuals aged 65 years and over living in Belgium as at 1 January 2002, and their survival during the year 2002. Data on health status are extracted from the 2001 census. We use binary logistic regression with the probability to die as outcome and living arrangement, health, age and gender as covariates. Our results show that mortality is more closely associated with actual living arrangements than with marital status. This association is age and gender-specific and remains even at very old ages. Living with a spouse is confirmed to be beneficial for survival but in older age living alone becomes more favourable. Of all living arrangements, older persons living in religious communities experience the lowest mortality risk whereas those living in nursing homes experience the highest risk.

How self-enhancers adapt well to loss: The mediational role of loneliness and social functioning

OBJECTIVE

The tendency toward unrealistically optimistic self-serving biases, known as trait self-enhancement, has been associated with both adaptive benefits and negative social consequences. This study explored these potential benefits and costs in the context of conjugal bereavement.

METHOD

The study included 94 individuals who had experienced the death of a spouse 1.5-3.0 years prior. The sample (62 female, 32 male) ranged in age from 37 to 60 (M = 51.45, SD = 6.08). To examine benefits, we used relatively objective measures of overall adjustment: structured clinical interviews and ratings from participants' close friends and relatives. To examine social adjustment, we examined friends'/relatives' ratings of the quality of social interactions and the possible mediating roles of perceived loneliness and friend/relative ratings.

RESULTS

Trait self-enhancement was uniformly associated with positive adjustment: relatively lower symptom totals, and friend/relative ratings of both overall better adjustment and better social adjustment. Self-enhancers' low loneliness was found to mediate reduced symptoms. Also, friends'/relatives' ratings of social functioning appeared to mediate self-enhancers' reduced loneliness.

CONCLUSIONS

These findings provide further empirical data to challenge the longstanding assumption that inaccurate self-perception is inherently maladaptive. Authentic benefits may result from mistaken perceptions of oneself by influencing the experience of loneliness and how one is seen by close friends/relatives. Self-enhancement may be an adaptation that provides clinically relevant advantages.

Life-Course Partnership Status and Biomarkers in Midlife: Evidence From the 1958 British Birth Cohort

OBJECTIVES

We examined the association between trajectories of partnership status over the life course and objectively measured health indicators in midlife.

METHODS

We used data from 4 waves (1981, 1991, 2000, and 2002-2004) of the British National Child Development Study (NCDS), a prospective cohort study that includes all people born in Britain during 1 week in March 1958 (n = 18 558).

RESULTS

After controlling for selection attributable to early-life and early-adulthood characteristics, we found that life-course trajectories of partnership status were associated with hemostatic and inflammatory markers, the prevalence of metabolic syndrome and respiratory function in midlife. Never marrying or cohabiting was negatively associated with health in midlife for both genders, but the effect was more pronounced in men. Women who had married in their late 20s or early 30s and remained married had the best health in midlife. Men and women in cohabiting unions had midlife health outcomes similar to those in formal marriages.

CONCLUSIONS

Partnership status over the life course has a cumulative effect on a wide range of objectively measured health indicators in midlife.

Urban/rural variation in the influence of widowhood on mortality risk: A cohort study of almost 300,000 couples

Death of a spouse is associated with increased mortality risk for the surviving partner (the widowhood effect). We investigated whether the effect magnitude varied between urban, rural and intermediate areas, assembling death records (2001-2009) for a prospective cohort of 296,125 married couples in Northern Ireland. The effect was greatest during the first six months of widowhood in all areas and for both sexes. Subsequently, the effect was attenuated among men in rural and intermediate areas but persisted in urban areas (HRs and 95% CIs: rural 1.09 [0.99, 1.21]; urban 1.35 [1.26, 1.44]). Among women the effect was attenuated in all areas (rural 1.06 [0.96, 1.17]; urban 1.09 [1.01, 1.17]). The impacts of spousal bereavement varied between urban and more rural areas, possibly due to variation in social support provided by the wider community. We identify men in urban areas as being in greatest need of such support and a possible target for health interventions.

Does the "widowhood effect" precede spousal bereavement? Results from a nationally representative sample of older adults

OBJECTIVE

Increased mortality risk following spousal bereavement (often called the "widowhood effect") is well documented, but little prior research has evaluated health deteriorations preceding spousal loss.

DESIGN

Data are from the Health and Retirement Study, a nationally representative sample of Americans over 50 years old.

METHOD

Individuals who were married in 2004 were considered for inclusion. Outcome data from 2006 on mobility (walking, climbing stairs), number of depressive symptoms, and instrumental activities of daily living (IADLs) were used. Exposure was characterized based on marital status at the time of outcome measurement: "recent widows" (N=396) were bereaved between 2004 and 2006, before outcomes were assessed; "near widows" (N=380) were bereaved between 2006 and 2008, after outcomes were assessed; "married" individuals (N=7,330) remained married from 2004 to 2010, the follow-up period for this analysis. Linear regression models predicting standardized mobility, depressive symptoms, and IADLs, were adjusted for age, race, gender, birthplace, socio-economic status, and health at baseline.

RESULTS

Compared to married individuals, recent widows had worse depressive symptoms (β=0.71, 95% confidence interval (CI): [0.57, 0.85]). Near widows had worse depressive symptoms (β=0.21, 95% CI: [0.08, 0.34]), mobility (β=0.14, 95%CI: [0.01, 0.26]), and word recall (β=-0.13, 95%CI: [-0.23, -0.02]) compared to married individuals.

CONCLUSIONS

Health declines before spousal death suggests some portion of the "widowhood effect" may be attributable to experiences that precede widowhood and interventions prior to bereavement might help preserve the health of the surviving spouse.

Association of stressful life events with accelerated bone loss in older men: the osteoporotic fractures in men (MrOS) study

Prior studies suggest an association between stressful life events and fractures that may be mediated by BMD. In the current study, risk of accelerated hip BMD loss was higher in older men with any type of stressful life event and increased with the number of types of stressful life events.

INTRODUCTION

Prior studies suggest that stressful life events may increase adverse health outcomes, including falls and possibly fractures. The current study builds on these findings and examines whether stressful life events are associated with increased bone loss.

METHODS

Four thousand three hundred eighty-eight men aged ≥65 years in the Osteoporotic Fractures in Men study completed total hip bone mineral density (BMD) measures at baseline and visit 2, approximately 4.6 years later, and self-reported stressful life events data mid-way between baseline and visit 2, and at visit 2. We used linear regression to model the association of stressful life events with concurrent annualized total hip BMD loss, and log binomial regression or Poisson regression to model risk of concurrent accelerated BMD loss (>1 SD more than mean annualized change).

RESULTS

Men (75.3 %) reported ≥1 type of stressful life event, including 43.3 % with ≥2 types of stressful life events. Mean annualized BMD loss was -0.36 % (SD 0.88), and 13.9 % of men were categorized with accelerated BMD loss (about 5.7 % or more total loss). Rate of annualized BMD loss increased with the number of types of stressful life events after adjustment for age (p < 0.001), but not after multivariable adjustment (p = 0.07). Multivariable-adjusted risk of accelerated BMD loss increased with the number of types of stressful life events (RR, 1.10 [95 % confidence interval (CI), 1.04-1.16]) per increase of one type of stressful life event). Fracture risk was not significantly different between stressful life event-accelerated bone loss subgroups (p = 0.08).

CONCLUSIONS

In these older men, stressful life events were associated with a small, dose-related increase in risk of concurrent accelerated hip bone loss. Low frequency of fractures limited assessment of whether rapid bone loss mediates any association of stressful life events with incident fractures. Future studies are needed to confirm these findings and to investigate the mechanism that may underlie this association.

Divergent gene expression responses to complicated grief and non-complicated grief

The "widowhood effect" (i.e., morbidity/mortality in recently bereaved spouses) may be related to changes in immune function, but little is known about the impact of bereavement on gene transcription in immune cells. This study examined how Complicated Grief and Non-complicated Grief responses to bereavement differentially affect leukocyte gene expression. Genome-wide transcriptional profiling and bioinformatic analyses were completed on 63 older adults. Thirty-six of them had lost their spouse/partner on average 2years ago, and 27 were nonbereaved, married controls. Twelve of the bereaved participants met criteria for Complicated Grief. Compared to nonbereaved controls, bereavement (both Complicated Grief and Non-complicated Grief) was associated with upregulated expression of genes involved in general immunologic activation and a selective downregulation of genes involved in B lymphocyte responses. However, Complicated Grief and Non-complicated Grief differed markedly in their expression of Type I interferon-related transcripts, with Non-complicated Grief subjects showing substantial upregulation relative to nonbereaved controls and Complicated Grief subjects showing substantial downregulation. Bereavement significantly modulates immune function gene expression. The magnitude of bereavement-related distress (i.e., Complicated Grief vs. Non-complicated Grief) is linked to differential patterns of transcription factor activation and gene expression involved in innate antiviral responses. These findings provide a molecular framework for understanding the health effects of bereavement, as well as new insights into the particular gene modules that are most sensitive to the individual's psychological response to loss.

Early life conditions, partnership histories, and mortality risk for Swedish men and women born 1915-1929

This paper investigates the relationship between early life biological and social factors, partnership history, and mortality risk. Mortality risks for Swedish men and women over age 50 in the Uppsala Birth Cohort born 1915-1929 were estimated using survival analysis. Relative mortality risk was evaluated through nested multiplicative Gompertz models for 4348 men and 3331 women, followed from age 50 to the end of 2010. Being born to an unmarried mother was associated with higher mortality risk in later life for men and women, and relative to married individuals, being unmarried after age 50 was associated with elevated mortality risk. Single women and divorced men were the highest risk groups, and women were negatively impacted by a previous divorce or widowhood, while men were not. Both genders showed direct effects of early life variables on later life mortality and were vulnerable if unmarried in later life. However, in this study, previous marital disruptions appeared to have more (negative) meaning in the long-term for women.

Patterns of widowhood mortality

OBJECTIVES

Becoming widowed is a known risk factor for mortality. This article examines the magnitude of, explanations for, and variation in the association between widowhood and mortality. Previous research on widowhood mortality has revealed variation by socioeconomic status (SES), in that SES is not protective in widowhood, and by gender, such that men's mortality increases more than women's mortality after the death of spouse.

METHOD

Using data from the Health and Retirement Study, we estimated Cox proportional hazard models to estimate the association between widowhood and mortality.

RESULTS

Becoming widowed is associated with a 48% increase in risk of mortality. Approximately one third of the increase can be attributed to selection, in that those who become widows are socioeconomically disadvantaged. In contrast to previous studies, SES is protective for widows. Widowhood mortality risk increases for men if their wives' deaths were unexpected rather than expected; for women, the extent to which their husbands' death was expected matters less.

DISCUSSION

Widowhood's harmful association with mortality show how strongly social support and individual's health and mortality are related. These findings support the larger literature on the importance of social support for health and longevity.

The unique impact of late-life bereavement and prolonged grief on diurnal cortisol

OBJECTIVES

This study expands on previous research by examining the effects of prolonged grief disorder (PGD) symptoms and bereavement on diurnal cortisol patterns above and beyond depressive symptomatology.

METHODS

Drawing on information from 56 depressed older adults, 3 groups were compared: (1) a depressed nonbereaved group, (2) a depressed bereaved without elevated PGD symptoms group, and (3) a depressed bereaved with elevated PGD symptoms group. Multilevel modeling was used to examine differences in diurnal cortisol profiles between these 3 groups, controlling for demographic factors and depressive symptoms.

RESULTS

Results revealed that those who were bereaved had more dysregulated cortisol patterns, but PGD symptomatology seemed to have little effect. Subsidiary analysis with just the bereaved participants suggests that those who were recently widowed may have had greater cortisol dysregulation compared with other bereaved individuals in the sample.

DISCUSSION

These findings suggest that the circumstance of being bereaved may be associated with more dysregulated cortisol, regardless of PGD symptomatology. This pattern of results might reflect greater disturbance in daily routines among bereaved individuals and acute stress in the case of those experiencing the recent loss of a spouse, which leads to disruption in circadian rhythms and the diurnal cycle of cortisol.

Association of stressful life events with incident falls and fractures in older men: the Osteoporotic Fractures in Men (MrOS) Study

BACKGROUND

small, retrospective studies suggest that major life events and/or sudden emotional stress may increase fall and fracture risk. The current study examines these associations prospectively.

METHODS

a total of 5,152 men aged ≥65 years in the Osteoporotic Fractures in Men study self-reported data on stressful life events for 1 year prior to study Visit 2. Incident falls and fractures were ascertained for 1 year after Visit 2. Fractures were centrally confirmed.

RESULTS

a total of 2,932 (56.9%) men reported ≥1 type of stressful life event. In men with complete stressful life event, fall and covariate data (n = 3,949), any stressful life event was associated with a 33% increased risk of incident fall [relative risk (RR) 1.33, 95% confidence interval (CI) 1.19-1.49] and 68% increased risk of multiple falls (RR = 1.68, 95% CI = 1.40-2.01) in the year following Visit 2 after adjustment for age, education, Parkinson's disease, diabetes, stroke, instrumental activities of daily living (IADL) impairment, chair stand time, walk speed, multiple past falls, depressive symptoms and antidepressant use. Risk increased with the number of types of stressful life events. Though any stressful life event was associated with a 58% increased age-adjusted risk for incident fracture, this association was attenuated and no longer statistically significant after additional adjustment for total hip bone mineral density, fracture after age 50, Parkinson's disease, stroke and IADL impairment.

CONCLUSIONS

in this cohort of older men, stressful life events significantly increased risk of incident falls independent of other explanatory variables, but did not independently increase incident fracture risk.

Short- and long-term associations between widowhood and mortality in the United States: longitudinal analyses

BACKGROUND

Past research shows that spousal death results in elevated mortality risk for the surviving spouse. However, most prior studies have inadequately controlled for socioeconomic status (SES), and it is unclear whether this 'widowhood effect' persists over time.

METHODS

Health and Retirement Study participants aged 50+ years and married in 1998 (n = 12 316) were followed through 2008 for widowhood status and mortality (2912 deaths). Discrete-time survival analysis was used to compare mortality for the widowed versus the married.

RESULTS

Odds of mortality during the first 3 months post-widowhood were significantly higher than in the continuously married (odds ratio (OR) for men = 1.87, 95% CI: 1.27, 2.75; OR for women = 1.47, 95% CI: 0.96, 2.24) in models adjusted for age, gender, race and baseline SES (education, household wealth and household income), behavioral risk factors and co-morbidities. Twelve months following bereavement, men experienced borderline elevated mortality (OR = 1.16, 95% CI: 1.00, 1.35), whereas women did not (OR = 1.07, 95% CI: 0.90, 1.28), though the gender difference was non-significant.

CONCLUSION

The 'widowhood effect' was not fully explained by adjusting for pre-widowhood SES and particularly elevated within the first few months after widowhood. These associations did not differ by sex.

Low preparedness before the loss of a wife to cancer and the widower's chronic pain 4-5 years later-a population-based study

OBJECTIVE

The focus of this study was on the impact of spousal loss on the development of chronic pain thereafter. More specifically, the aim was to investigate the effect of experiencing low preparedness before a wife's death and the widower's chronic pain 4-5 years after loss.

METHODS

In a population-based study in the years 2004-2005, anonymous questionnaires were sent out to 907 men in Sweden who had lost a wife to cancer in 2000 and 2001. The questionnaires contained questions on the man's preparedness for his wife's death and his physical and psychological health at follow-up.

RESULTS

Altogether, 691 out of 907 questionnaires were retrieved (76%). Younger widowers (38-61 years old) with a low degree of preparedness for their wife's death had an increased risk of experiencing symptoms of chronic pain (odds ratio 6.67; 2.49-17.82) 4-5 years after loss. The same results did not apply for older widowers (62-80 years old) (odds ratio 0.81; 0.32-2.05). Widowers who experienced chronic pain were at an increased risk for psychological morbidity, depression (relative risk [RR] 2.21; 1.31-3.74), anxiety (RR 2.11; 1.33-3.37), and sleep disorders (RR 2.19; 1.30-3.69).

CONCLUSION

Our data suggest that low preparedness for a wife's death may increase risk of chronic pain among younger widowers 4-5 years after loss. In addition, we found comorbidity between psychological symptoms and chronic pain among widowers. These findings call for studies on possible mechanisms in the association between low preparedness and morbidity and on how to increase preparedness for a wife's death to cancer.

The effect of unexpected bereavement on mortality in older couples

OBJECTIVES

We sought to determine whether unexpected bereavement has a greater impact on mortality in the surviving partner than death of a partner with preexisting chronic disease or disability.

METHODS

In a UK primary care database (The Health Improvement Network), we identified 171,720 couples aged 60 years and older. We compared the rise in mortality in the first year after bereavement in those whose partner died without recorded chronic disease (unexpected bereavement) to those whose deceased partner had a diagnosis of chronic disease (known morbidity).

RESULTS

For unexpected bereavement (13.4% of all bereavements), the adjusted hazard ratio for death in the first year after bereavement was 1.61 (95% confidence interval [CI] = 1.39, 1.86) compared with 1.21 (95% CI = 1.14, 1.30) where the partner had known morbidity. Differences between bereaved groups were significant (P = .001) and present for both men and women.

CONCLUSIONS

Unexpected bereavement has a greater relative mortality impact than bereavement preceded by chronic disease. Our findings highlight the potential value of preparing individuals for the death of a spouse with known morbidity and providing extra support after bereavement for those experiencing sudden unexpected bereavement.

The short-term and long-term effects of divorce on mortality risk in a large Finnish cohort, 1990-2003

This study investigated time patterns of post-divorce excess mortality. Using register-based data, we followed 252,641 married Finns from 1990 until subsequent date of divorce and death until 2003. Among men, excess mortality is highest immediately after divorce, followed by a decline over 8 years. Among women, excess mortality shows little variation over time, and is lower than among men at all durations of divorce. Social and economic factors--largely adjustment for post-divorce factors--explain about half of the excess mortality. This suggests that excess mortality is partly mediated through poor social and economic resources. Mortality attributable to accidental, violent, and alcohol-related causes is pronounced shortly after divorce. It shows a strong pattern of reduction over the next 4 years among divorced men, and is high for only 6 months after divorce among divorced women. These findings emphasize the importance of short-term psychological distress, particularly among men.

Do good health and material circumstances protect older people from the increased risk of death after bereavement?

An increased risk of death in persons who have suffered spousal bereavement has been described in many populations. The impact of modifying factors, such as chronic disease and material circumstances, is less well understood. The authors followed 171,120 couples 60 years of age or older in a United Kingdom primary care database between 2005 and 2010 for an average of 4 years. A total of 26,646 (15.5%) couples experienced bereavement, with mean follow up after bereavement of 2 years. In a model adjusted for age, sex, comorbid conditions at baseline, material deprivation based on area of residence, season, and smoking status, the hazard ratio for mortality in the first year after bereavement was 1.25 (95% confidence interval: 1.18, 1.33). Further adjustment for changes in comorbid conditions throughout follow up did not alter the hazard ratio for bereavement (hazard ratio = 1.27, 95% confidence interval: 1.19, 1.35). The association was strongest in individuals with no significant chronic comorbid conditions throughout follow up (hazard ratio = 1.50, 95% confidence interval: 1.28, 1.77) and in more affluent couples (P = 0.035). In the first year after bereavement, the association between bereavement and death is not primarily mediated through worsening or new onset of chronic disease. Good health and material circumstances do not protect individuals from increased mortality rates after bereavement.

Psychosocial stressors in inter-human relationships and health at each life stage: A review

Currently, psychosocial stressors' impacts on health are increasing. Among these stressors, this review focused on inter-human relationships. Since social supports could be protective against ill health, consequences contributing to psychosocial stressors are discussed here in relation to social supports for each stage of childhood, adulthood and elderly status.For childhood, parental divorce/isolation, and child abuse/neglect appeared to be determinants of healthy development at either the initial or later stages. According to prospective studies, such stressors, especially those occurring until around 3 years of age, were associated with later adverse life quality in adulthood. Therefore, nationwide preventive strategies were developed in each country to monitor protective social programs.For adulthood, job strain was focused on Karasek's job strain model, effort-reward imbalance, employment grade and working hours. These psychosocial stressors were shown to affect not only the physical health but also the mental health of working people. These days, since Karoshi and even suicide related to excessive workloads are taking a toll on workplace organization, stress-coping abilities such as a sense of coherence were introduced from the individual-social interaction aspect.For elderly status, retirement, caring for the elderly, and spouse bereavement were discussed as psychosocial stressors. Some evidence indicates that these stressors could be determiants of health. Finally, social supports have been demonstrated to promote health and protect the elderly against diseases and death.

Marital status, health and mortality

Marital status and living arrangements, along with changes in these in mid-life and older ages, have implications for an individual's health and mortality. Literature on health and mortality by marital status has consistently identified that unmarried individuals generally report poorer health and have a higher mortality risk than their married counterparts, with men being particularly affected in this respect. With evidence of increasing changes in partnership and living arrangements in older ages, with rising divorce amongst younger cohorts offsetting the lower risk of widowhood, it is important to consider the implications of such changes for health in later life. Within research which has examined changes in marital status and living arrangements in later life a key distinction has been between work using cross-sectional data and that which has used longitudinal data. In this context, two key debates have been the focus of research; firstly, research pointing to a possible selection of less healthy individuals into singlehood, separation or divorce, while the second debate relates to the extent to which an individual's transitions earlier in the life course in terms of marital status and living arrangements have a differential impact on their health and mortality compared with transitions over shorter time periods. After reviewing the relevant literature, this paper argues that in order to fully account for changes in living arrangements as a determinant of health and mortality transitions, future research will increasingly need to consider a longer perspective and take into account transitions in living arrangements throughout an individual's life course rather than simply focussing at one stage of the life course.

Widowhood and mortality: a meta-analysis and meta-regression

The study of spousal bereavement and mortality has long been a major topic of interest for social scientists, but much remains unknown with respect to important moderating factors, such as age, follow-up duration, and geographic region. The present study examines these factors using meta-analysis. Keyword searches were conducted in multiple electronic databases, supplemented by extensive iterative hand searches. We extracted 1,377 mortality risk estimates from 123 publications, providing data on more than 500 million persons. Compared with married people, widowers had a mean hazard ratio (HR) of 1.23 (95% confidence interval (CI), 1.19-1.28) among HRs adjusted for age and additional covariates and a high subjective quality score. The mean HR was higher for men (HR, 1.27; 95% CI, 1.19-1.35) than for women (HR, 1.15; 95% CI, 1.08-1.22). A significant interaction effect was found between gender and mean age, with HRs decreasing more rapidly for men than for women as age increased. Other significant predictors of HR magnitude included sample size, geographic region, level of statistical adjustment, and study quality.

Gender differences in widowhood effects among community-dwelling elders by causes of death in Taiwan

PURPOSE

We sought to determine whether widowhood-associated excess mortality differs by gender in terms of causes of death.

METHODS

Data were collected from a five-wave interview of approximately 2500 community-dwelling elders in the Survey of Health and Living Status of the Nearly Elderly and Elderly. Baseline characteristics were used to derive the risk score (RS) to reflect individual's baseline pre-widowhood vulnerability. Time-dependent Cox regression analyses were used to estimate spousal loss-related mortality by causes.

RESULTS

For males, the adjusted hazard ratios (aHRs) of widowhood for all-cause and some major causes of death (e.g., neoplasm) increased inversely with RS: the aHRs for all-cause death were 4.81 and 1.76 in the lowest and highest RS groups, respectively. In contrast, the corresponding aHRs were relatively homogeneous for women (1.52 and 1.70).

CONCLUSIONS

Identifying gender heterogeneity in widowhood effects can guide further efforts to devise gender-tailored programs to enhance healthy aging.

Assessing survival in widowers, and controls - a nationwide, six- to nine-year follow-up

BACKGROUND

The aim of this study was to assess if widowers had an increased mortality rate during the first 6 to 9 years after the death of their wife, compared initially to an age-matched control group and also compared to the general population of Iceland.

METHODS

The study base was comprised of all 371 men born in 1924-1969 who were widowed in Iceland in 1999-2001 and 357 controls, married men, who were matched by age and residence.The widowers and controls were followed through the years 2002-2007 using information from Statistics Iceland. Mortality rates were compared between the groups and also with the general population. The mortality rate comparisons were: study group vs. control group, on the one hand, and study group vs. general population on the other. Causes of death were also compared between widowers and their wives.

RESULTS

A statistically significant increase in mortality in the widowers' group, compared to controls, was observed.Lifestyle-related factors could not be excluded as contributing to cause of death in these cases.

CONCLUSIONS

Being a widower was related to an increased risk of death for at least 9 years after the death of their wife.

Long-term mental health of men who lose a wife to cancer--a population-based follow-up

OBJECTIVE

This study investigated the long-term risk of psychological morbidity for men after losing a wife to cancer. A further aim of the study was to investigate if being in a new relationship at the time of follow-up affects the risk of psychological morbidity.

METHOD

In a population-based cohort study, we collected data from 907 men in Sweden who lost a wife to cancer in the breast, ovary or colon 4-5 years earlier. A control group of 330 married men was also included.

RESULTS

Six hundred ninety-one of the widowers (76%) and 262 of the controls (79%) answered a questionnaire. Widowers in a new relationship had a similar risk of psychological morbidity compared with a control group of married men. However, compared with widowers in a new relationship, single widowers reported increased risks of (among other symptoms) the following: depression (RR 2.2, confidence interval [CI] 1.5-3.2), anxiety (RR 1.6, CI 1.1-2.5) emotional numbness (RR 2.2, CI 1.7-2.8), and waking up at night with anxiety (RR 2.2, CI 1.4-3.7).

CONCLUSIONS

Men who lost a wife to cancer in Sweden in 2000 or 2001 and are single 4-5 years later have increased risks of psychological morbidity, both compared with widowers who are in a new relationship at the time of follow-up and with married men. Further scientific effort is needed for improved understanding of the most likely underlying mechanisms; that is, that enhanced emotional support of a new relationship after the loss of a wife protects against psychological morbidity, or alternatively, that the healthiest widowers enter a new relationship.

Widowhood and mortality: a meta-analysis

Background

While the "widowhood effect" is well known, there is substantial heterogeneity in the magnitude of effects reported in different studies. We conducted a meta-analysis of widowhood and mortality, focusing on longitudinal studies with follow-up from the time of bereavement.

Methods and Findings

A random-effects meta-analysis was conducted to calculate the overall relative risk (RR) for subsequent mortality among 2,263,888 subjects from 15 prospective cohort studies. We found a statistically significant positive association between widowhood and mortality, but the widowhood effect was stronger in the period earlier than six months since bereavement (overall RR = 1.41, 95% CI: 1.26, 1.57) compared to the effect after six months (overall RR = 1.14, 95% CI: 1.10, 1.18). Meta-regression showed that the widowhood effect was not different for those aged younger than 65 years compared to those older than 65 (P = 0.25). There was, however, a difference in the magnitude of the widowhood effect by gender; for women the RR was not statistically significantly different from the null (overall RR = 1.04, 95% CI: 1.00, 1.08), while it was for men (overall RR = 1.23, 95% CI: 1.18, 1.28).

Conclusions

The results suggest that further studies should focus more on the mechanisms that generate this association especially among men.

Conjugal bereavement effects on health and mortality at advanced ages

Spousal bereavement at old ages may lead to dramatic changes in health. This paper investigates whether spousal bereavement has a causal effect on health and on mortality of the surviving spouse. We advance on the literature in two main ways. First, we model survivals of both spouses and the dynamic evolution of health jointly, allowing for potential endogeneity of timing of bereavement and health in explaining mortality of the surviving spouse. Second, we use a flexible non-parametric data dimensionality reduction method to thoroughly characterize health (using 22 health indicators) by a limited number of latent health indicators. This allows us to investigate the causal effect of spousal bereavement on mortality and on all aspects of health simultaneously. Our analyses are based on an ongoing longitudinal survey that follows a random sample of older individuals from 1992. We find strong instantaneous effects of bereavement on mortality and on certain aspects of health. Individuals lose on average 12% of residual life expectancy after conjugal bereavement. Conjugal bereavement affects the share of healthy years in residual lifetime, primarily because healthy years are replaced by years with chronic diseases. The strong direct effects of bereavement suggest that monitoring and/or interventions just after spousal bereavement are important for the length and quality of life of older bereaved individuals.
