On becoming depressed or anxious in late life: similar vulnerability factors but different effects of stressful life events

Temperament Based Personality Types in Community-Dwelling Older Adults: A Latent Profile Analysis

Three adaptive trait-based personality types have been replicated across ages, cultures, clinical problems and clustering methods: Resilient, Undercontrolled and Overcontrolled type (RUO). Recently there is growing interest in and importance of biopsychosocial transdiagnostic factors underlying personality types, such as temperamental reactivity and self-regulation. Latter can be understood in terms of Behavioural Inhibition (BIS), Behavioural Activation Systems (BAS) and Effortful Control (EC). The occurrence of temperament based RUO types has not yet been confirmed in older adults with or without a mental disorder. Therefore, based on a person-centered approach, the current study investigates whether RUO types can be corroborated in older adults based on the aforementioned temperamental factors. Latent profile analysis yielded two distinct personality profiles in community-dwelling over-60s, which we tentatively labeled a resilient (n = 167) and overcontrolled/inhibited type (n = 241). Compared to the resilient type, the overcontrolled/inhibited type scored lower on EC and higher on BIS. We could not corroborate an undercontrolled type (profiles scored equally on BAS). Group comparisons revealed that overcontrolled/inhibited older adults demonstrated significantly more clinical symptoms, higher emotional instability, lower scores on adaptive traits, less resilience and were significantly more likely to use passive and avoidant coping styles, compared to resilient older adults.

Cretan Aging Cohort-Phase III: Methodology and Descriptive Characteristics of a Long-Term Longitudinal Study on Predictors of Cognitive Decline in Non-Demented Elderly from Crete, Greece

Identifying modifiable factors that may predict long-term cognitive decline in the elderly with adequate daily functionality is critical. Such factors may include poor sleep quality and quantity, sleep-related breathing disorders, inflammatory cytokines and stress hormones, as well as mental health problems. This work reports the methodology and descriptive characteristics of a long-term, multidisciplinary study on modifiable risk factors for cognitive status progression, focusing on the 7-year follow-up. Participants were recruited from a large community-dwelling cohort residing in Crete, Greece (CAC; Cretan Aging Cohort). Baseline assessments were conducted in 2013-2014 (Phase I and II, circa 6-month time interval) and follow-up in 2020-2022 (Phase III). In total, 151 individuals completed the Phase III evaluation. Of those, 71 were cognitively non-impaired (CNI group) in Phase II and 80 had been diagnosed with mild cognitive impairment (MCI). In addition to sociodemographic, lifestyle, medical, neuropsychological, and neuropsychiatric data, objective sleep was assessed based on actigraphy (Phase II and III) and home polysomnography (Phase III), while inflammation markers and stress hormones were measured in both phases. Despite the homogeneity of the sample in most sociodemographic indices, MCI persons were significantly older (mean age = 75.03 years, SD = 6.34) and genetically predisposed for cognitive deterioration (APOE ε4 allele carriership). Also, at follow-up, we detected a significant increase in self-reported anxiety symptoms along with a substantial rise in psychotropic medication use and incidence of major medical morbidities. The longitudinal design of the CAC study may provide significant data on possible modifiable factors in the course of cognitive progression in the community-dwelling elderly.

Stress-related to COVID-19, anxiety, and protective factors among middle-aged and older adults in the largest outbreak areas in South Korea

OBJECTIVES

The present study examined the impact of psychological stress related to COVID-19 on anxiety as well as protective factors against these negative psychological consequences among middle-aged and older adults in the largest outbreak areas in South Korea.

METHOD

Participants included 667 middle-aged and older adults (ages 40 to 76) living in the largest outbreak areas at the time of the survey based on the number of confirmed COVID-19 cases in South Korea. Path analysis was conducted.

RESULTS

Stress related to COVID-19 and loneliness were positively associated with anxiety. However, family cohesion, resilience, health, and being married were negatively associated with anxiety. Also, family cohesion, resilience, income, and being married were negatively associated with loneliness among middle-aged and older adults in the largest outbreak areas in South Korea.

CONCLUSION

As postulated by the Stress Process Model, stress related to COVID-19 may have increased loneliness and anxiety among middle-aged and older adults in the largest outbreak areas in South Korea; however, resilience and family cohesion reduced these negative consequences both directly and indirectly. Findings are discussed and implications are addressed.

Childhood adversities, late-life stressors and the onset of depressive symptoms in community-dwelling older adults

Objective: Depression is common in older individuals though many factors associated with its occurrence remain under-researched. We examined whether childhood adversities (CAs) and late-life stressors are associated with the onset of depressive symptoms in adults aged ≥ 65 and if these early- and late-life stressors interact in the prediction of depressive symptoms. Methods: Data came from the 2010 and 2013 waves of the Japan Gerontological Evaluation Study (JAGES) (N = 8701). The Geriatric Depression Scale (GDS-15) was used to assess the presence of depressive symptoms (GDS ≥ 5). A Poisson regression analysis was used to examine associations. Results: Both CAs (1 event: incidence rate ratio [IRR] = 1.59, 95% confidence interval [CI]: 1.41-1.79; ≥ 2 events: IRR = 2.36, 95% CI = 1.80-3.10) and late-life stressful events (1 event: IRR = 1.13, 95% CI: 1.02-1.25; ≥ 2 events: IRR = 1.25, 95% CI = 1.05-1.50) were significantly associated with the onset of depressive symptoms. Borderline significant interactions between CAs and late-life stressors (e.g. ≥ 2 CAs and ≥ 2 late-life events: IRR = 0.61, p = 0.087) suggest that late-life stressors may be important in predicting the onset of depressive symptoms especially among individuals with no or fewer CAs compared to those with ≥ 2 CAs. Conclusions: Stressful events in childhood and late adulthood were independently associated with the onset of depressive symptoms in older adults. In addition, stressful experiences in childhood might affect how individuals respond to stressful events in later life.

Three-year prediction of depression and anxiety with a single self-rated health item

BACKGROUND

Self-rated health (SRH) is a single question with which general health status is assessed.

AIMS

To study whether SRH (i) is associated with depression and anxiety symptoms, concurrently and after three years, (ii) predicts the course over time for meeting a cutoff for depression and anxiety, and (iii) predicts development of depression and anxiety after three years.

METHOD

Population-based questionnaire data from northern Sweden were used. In total, 2336 individuals participated at baseline and three-year follow-up. The Hospital Anxiety and Depression Scale was used to quantify symptoms of depression and anxiety. Categorical and continuous data were used for analyses to complement each other.

RESULTS

Regarding prevalence, the analyses showed three- to four-fold increased odds for depression and anxiety at three-year follow-up, and two- to three-fold odds for their development at three-year follow-up. SRH at baseline was also found to be a significant, but weak, predictor of depression and anxiety severity and worsening at follow-up as well as being a predictor over time for meeting a cutoff for depression and anxiety.

CONCLUSIONS

Assessment of SRH may be used in general practice to identify individuals who qualify for further evaluation of depression and anxiety.

Trends in benzodiazepine and alternative hypnotic use in relation with multimorbidity among older adults in Quebec, Canada

BACKGROUND

Benzodiazepines and other hypnotic alternatives are associated with increased risks of adverse events. Heightened awareness of risks may have changed prescribing habits over the years. However, these trends are not fully described, especially in vulnerable people such as multimorbid older adults.

OBJECTIVE

We aimed to describe the annual prevalence of benzodiazepine and other hypnotic use in relation to multimorbidity among older adults in the province of Quebec, Canada, from 2000 to 2016.

METHOD

We conducted a population-based study using the Quebec Integrated Chronic Disease Surveillance System. We included all individuals aged ≥66 years covered by the public drug plan. For each year, we evaluated the sex- and age-standardized proportion of benzodiazepine and other hypnotic users, defined as individuals with at least one drug claim in the year. We stratified our results according to multimorbidity and used log-binomial regression to study trends.

RESULTS

The proportion of individuals using benzodiazepines decreased from 34.8% in 2000 to 24.8% in 2016 (p for trend <0.001). Multimorbid people (≥2 chronic diseases) remained the highest users over the years, with 43.3% and 30.6% of them being users in 2000 and 2016, respectively. Conversely, the proportion of users increased for other hypnotics, particularly for trazodone and quetiapine, rising from 5.4% to 8.4% (p < 0.001), and especially among multimorbid individuals (from 7.4% to 11.6%).

CONCLUSION

Older adults used benzodiazepines less frequently but quetiapine and trazodone more frequently in recent years. The use of these medications, particularly in multimorbid people at risk of adverse events, must be addressed.

Latent class growth modeling of depression and anxiety in older adults: an 8-year follow-up of a population-based study

BACKGROUND

Depression and anxiety are common mental health conditions in the older adult population. Understanding the trajectories of these will help implement treatments and interventions.

AIMS

This study aims to identify depression and anxiety trajectories in older adults, evaluate the interrelationship of these conditions, and recognize trajectory-predicting characteristics.

METHODS

Group-based dual trajectory modeling (GBDTM) was applied to the data of 3983 individuals, aged 65 years or older who participated in the Korean Health Panel Study between 2008 and 2015. Logistic regression was used to identify the association between characteristics and trajectory groups.

RESULTS

Four trajectory groups from GBDTM were identified within both depression and anxiety outcomes. Depression outcome fell into "low-flat (87.0%)", "low-to-middle (8.8%)", "low-to-high (1.3%)" and "high-stable (2.8%)" trajectory groups. Anxiety outcome fell into "low-flat (92.5%)", "low-to-middle (4.7%)", "high-to-low (2.2%)" and "high-curve (0.6%)" trajectory groups. Interrelationships between depression and anxiety were identified. Members of the high-stable depression group were more likely to have "high-to-low" or "high-curved" anxiety trajectories. Female sex, the presence of more than three chronic diseases, and being engaged in income-generating activity were significant predictors for depression and anxiety.

CONCLUSIONS

Dual trajectory analysis of depression and anxiety in older adults shows that when one condition is present, the probability of the other is increased. Sex, having more than three chronic diseases, and not being involved in income-generating activity might increase risks for both depression and anxiety. Health policy decision-makers may use our findings to develop strategies for preventing both depression and anxiety in older adults.

Prevalence and risk factors of anxiety and depression among the community-dwelling elderly in Nay Pyi Taw Union Territory, Myanmar

Providing elderly mental healthcare in Myanmar is challenging due to the growing elderly population and limited health resources. To understand common mental health problems among Myanmar elderly, this study explored the prevalence and risk factors of anxiety and depression among the elderly in the Nay Pyi Taw Union Territory, Myanmar. A cross-sectional study was conducted among 655 elderly by face-to-face interviews with a pretested questionnaire. Descriptive analysis and multiple logistic regression analyses were performed. The prevalence of anxiety and depression were 39.4% (33.5% for males and 42.4% for females) and 35.6% (33.0% for males and 36.9% for females), respectively. The adjusted odds ratio of having anxiety was significant for having low education level, having comorbidity, having BMI < 21.3, poor dental health, no social participation, and having no one to consult regarding personal problems, while that of having depression was significant for having comorbidity, having BMI < 21.3, poor vision, and having no one to consult regarding personal problems. The reported prevalence of anxiety and depression indicate the demand for mental healthcare services among Myanmar elderly. Myanmar needs to improve its elderly care, mental healthcare, and social security system to reflect the actual needs of its increasing elderly population. Screening for anxiety and depression among elderly with comorbidities should be promoted. Raising community awareness of mental health, encouraging social participation, and supportive counselling are also essential in combating anxiety and depression among Myanmar elderly.

Gender convergence or divergence in the relationship between late-life depression and multiple stressors: evidence from a national survey in China

This study aimed to investigate gender convergence or divergence among older adults in China, a Confucian society with strong persistence of gender role differentiation. We examined how multiple stressors influence depression simultaneously, with gender comparison approach. The data were drawn from the China Longitudinal Aging Social Survey study (N = 8,097). Results indicated that older women reported significantly higher levels of depression than men, yet overall depressive symptoms showed many gender similarities. Surprisingly, our analyses supported the hypothesis of gender convergence in stressors predicting late-life depression. Recommendations for practice and further research priorities based on findings are discussed.

Stressful Events in Old Age: Who are Most Exposed and Who are Most Likely to Overcome Them

Objectives: This study investigated self-reported events that were rated as stressful and being affecting wellbeing among older people. It also examined the variables associated with the perception of overcoming these stressful events. Methods: Face-to-face survey on a representative sample of 1,431 older people in Santiago-Chile. Instruments included open-ended questions for distinguishing events as losses, problems, conflicts, and others’ difficulties. The associations between the occurrence and overcoming of events with individual and social characteristics were examined through multivariate logistic regression. Results: 39.5% mentioned at least one stressful event, being mostly perceived as solvable problems rather than losses. Higher-income, better health, self-efficacy, and social support were associated with a higher perception of event overcoming. Conclusion: The occurrence and the probability of events’ overcoming does not increase in old-old age in this sample group. Better health and individual and social resources such as self-efficacy and social support, are protective resources for overcoming the stressful events, but they are not generally considered in public policies.

Contribution of psychosocial factors to socioeconomic inequalities in mortality among older Australian men: a population-based cohort study

BACKGROUND

Among older people, the extent to which psychosocial factors explain socioeconomic inequalities in mortality is debated. We aimed to investigate the potential mediating effect of psychosocial factors on socioeconomic inequalities in mortality.

METHODS

We used data from a prospective population-based cohort (the Concord Health and Ageing in Men Project; baseline recruitment in 2005-2007), in Sydney, Australia. The main outcomes were all-cause and cause-specific mortality. Socioeconomic status (SES; educational attainment, occupational position, source of income, housing tenure, and a cumulative SES score) was assessed at baseline. Measures of structural and functional social support, as well as depressive and anxiety symptoms were assessed three times during follow-ups. Associations were quantified using Cox regression. Mediation was calculated using "change-in-estimate method".

RESULTS

1522 men (mean age at baseline: 77·4 ± 5·5 years) were included in the analyses with a mean (SD) follow-up time of 9·0 (3·6) years for all-cause and 8·0 (2·8) years for cause-specific mortality. At baseline, psychosocial measures displayed marked social patterning. Being unmarried, living alone, low social interactions, and elevated depressive symptoms were associated with higher risk of all-cause and cardiovascular disease (CVD) mortality. Psychosocial factors explained 35% of SES inequalities in all-cause mortality, 29% in CVD mortality, 12% in cancer mortality, and 39% in non-CVD, non-cancer mortality.

CONCLUSION

Psychosocial factors may account for up to one-third of SES inequalities in deaths from all and specific causes (except cancer mortality). Our findings suggest that interventional studies targeting social relationships and/or psychological distress in older men aiming to reduce socioeconomic inequalities in mortality are warranted.

Personal, behavioral, and perceived environmental factors associated with late-life depression in older men and women

INTRODUCTION

Previous investigations on factors associated with depression were highly focused on personal characteristics and health behaviors; however, few studies used an ecological perspective on the issue, much less on sex differences. This study examined the factors associated with depression, including any sex differences.

METHODS

A total of 1025 Taiwanese adults older than 65 years were recruited. Their personal demographics, lifestyle behaviors, and perceived environmental factors were obtained through a telephone-based survey. The multiple factors associated with depression in older adults were examined using logistic regression analyses.

RESULTS

Fully logistic regression analyses revealed that poor self-rated health (odds ratio =2.54) was correlated with a greater likelihood of depression. Aside from poor self-rated health, being older, sufficient leisure time spent in walking, and perceptions of a safe environment were associated with lower risks of depression in older men, whereas having hypertension and excessive TV viewing were associated with higher risks of depression in older women.

CONCLUSION

Apart from self-rated health, sex differences in the associations of factors such as leisure-time walking, TV watching, and safe traffic environment with depression were observed among older adults. Strategies applied for geriatric depression prevention should take into consideration different sex group.

Determinants for concomitant anxiety and depression in people living with chronic obstructive pulmonary disease

OBJECTIVE

Anxiety and depression are common comorbidities in people diagnosed with chronic obstructive pulmonary disease (COPD). Despite concomitant psychological symptomatology being reported in 22-48% of people with COPD, most literature focuses on identifying the risk factors for anxiety or depression separately. Therefore, our objective was to determine whether there is an association between people living with concomitant anxiety and depression and sociodemographic risk factors in people and living with COPD.

METHODS

This was a cross-sectional study of 242 people living with COPD. Symptomatology of anxiety and depression were assessed using the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI-II). Univariate and multivariable logistic regression models were used to test the association between symptomatology and demographic predictor variables. Odds ratios and 95% confidence intervals were derived.

RESULTS

Of the 242 people included, 48.8% (n = 118) had no symptoms of anxiety or depression and 33.5%% (n = 81) had symptomatology for both. Multivariable modelling suggested younger age, having a carer, having a previous psychological medical history, having a higher number of comorbidities and poorer quality of life were associated with concomitant anxiety and depression compared to those without symptomatology.

CONCLUSION

Further work should be done to build upon our results which adds to the limited literature surrounding risk factors for concomitant psychological symptomatology to facilitate future discussion surrounding reducing these detrimental comorbidities in people with COPD.

Levels of neuroticism differentially predict individual scores in the depression and anxiety dimensions of the tripartite model: A multiwave longitudinal study

The associations between neuroticism and depression and anxiety symptoms remain unclear possibly due to the lack of specificity and covariation among common symptoms. The current study hypothesized that neuroticism acts as a vulnerability factor for general distress (GD) and specific depression and anxiety symptoms. We investigated this hypothesis using the "tripartite model" (a well-known dimensional model of anxiety and depression). A sample of 644 college students was recruited from Hunan, China. In the initial stage of this investigation, the students completed self-assessment forms to measure their levels of neuroticism and frequency of daily hassles. The students also reported on their levels of GD and specific depression and anxiety symptoms. The same self-assessment procedure was undertaken once a month for the next 6 months. The results of the hierarchical linear model suggest a significant interaction between neuroticism and the level of stress caused by exposure to increased levels of daily hassles, which can be used as a predictor of future levels of GD and specific anxiety symptoms. However, the same interaction was not a significant predictor of specific depression symptoms. The current findings suggest that neuroticism may be a risk factor for specific anxiety but not for specific depression symptoms in face of stress caused by daily hassles.

The Factors Associated With Anxiety Symptom Severity in Older Adults Living in Nursing Homes and Other Residential Aged Care Facilities

Objective: This study aimed to identify the biopsychosocial factors associated with anxiety among a residential aged care sample. Method: A total of 178 residents ( M age = 85.4 years, SD = 7.4 years) with mild cognitive impairment or normal cognition participated. Participants completed the Geriatric Anxiety Inventory (GAI) and a set of measures assessing cognition, depression, self-perceived health, mastery, attachment, perceived social support, social engagement, functional status, the experience of a fall, and other negative life events. Results: Unique correlates of GAI scores were depression, a preoccupied attachment style, lower mastery, cognitive impairment, and lower self-perceived health. Discussion: Most correlates that were uniquely associated with anxiety had little to do with the current environment. More variance was accounted for by stable and lifelong factors. This provides new insights into the characteristics of anxiety within aged care populations, and although preliminary, provides possible targets to prevent and treat anxiety within this setting.

Anxiety symptoms and risk of dementia and mild cognitive impairment in the oldest old women

OBJECTIVES

Research is limited and findings conflict regarding anxiety as a predictor of future cognitive decline in the oldest old persons. We examined the relationship between levels of and changes in anxiety symptoms, and subsequent dementia and mild cognitive impairment (MCI) in the oldest old women.

METHOD

We conducted secondary analyses of data collected from 1425 community-dwelling women (mean age = 82.8, SD ±3.1 years) followed on average for five years. The Goldberg Anxiety Scale was used to assess anxiety symptoms at baseline, and an expert clinical panel adjudicated dementia and MCI at follow-up. Participants with probable cognitive impairment at baseline were excluded.

RESULTS

At baseline, 190 (13%) women had moderate/severe anxiety symptoms and 403 (28%) had mild anxiety symptoms. Compared with those with no anxiety symptoms at baseline, women with mild anxiety symptoms were more likely to develop dementia at follow-up (multivariable-adjusted odds ratio = 1.66, 95% confidence interval 1.12-2.45). No significant association was observed between anxiety symptoms and MCI.

CONCLUSION

In the oldest old women, our findings suggest that mild anxiety symptoms may predict future risk of dementia, but not MCI. Future studies should explore potential biological mechanisms underlying associations of anxiety with cognitive impairment.

The Incidence of Depression and Anxiety Among the Elderly in the Area of Livno, Bosnia and Herzegovina

Introduction

The most common mental disorders in elderly, beside dementia, are depression and anxiety, which are important public health problem, although they are diagnosed and treated in under 20% of the population. Mental health care for elderly is one of the indicators of quality or omissions in the health system of a country.

Aim

The aim of the study was to examine the incidence of depression and anxiety among the elderly in the Livno area.

Material and methods

Across-sectional study was carried out in the Livno area through June 2017 on a sample of 100 respondents (N=100). Inclusion criteria: age over 65 years. Exclusion criteria: persons with malignancy, persons with psychiatric diagnosis or dementia. Research tools used: Questionnaire on sociodemographic status and Hospital Anxiety and Depression Self Evaluation Scale (HAD).

Results

More than 90% of the respondents of both genders were estimated to be borderline depressed or depressed. There was a higher incidence of depression among male respondents, and anxiety among female respondents. Probably and borderline anxiety is recorded in 84% of respondents, which exceed the results of all available literature data. Religious habits have no influence on the occurrence of depression but there is a connection between prayer and anxiety occurrence.

Conclusion

This research has established an extremely high incidence of depression and anxiety among the elderly in the Livno area. The results of the available studies indicate significantly lower rates of occurrence than in the tested sample. Socioeconomic status did not prove to be a significant predictor of the occurrence of these disorders.

Neuroticism Predicts Acculturative Stress in Mexican American College Students

Neuroticism is a risk factor for mood and anxiety disorders and a strong predictor of subjective stress in non-Hispanics. This study examined neuroticism as a predictor of subjective acculturative stress in 122 Mexican American college students. Neuroticism was measured using the Revised Neuroticism Extroversion Openness Personality Inventory (NEO-PI-R), and acculturative stress was measured using the Hispanic Stress Inventory (HSI). Results of hierarchical regression analyses showed that overall neuroticism and the facets of depression, vulnerability, and anger and/or hostility significantly predicted acculturative stress. The association between neuroticism and greater subjective psychosocial stress can now be extended to acculturative stress for a subgroup of Mexican Americans. Findings support and extend previous work from the authors' laboratory suggesting that neuroticism modulates the relationship between exposure to culturally specific stress and risk for certain mood and anxiety disorders.

Resilience, stressful life events, and depressive symptomatology among older Chinese adults

OBJECTIVE

The association between exposure to stressful life events (SLEs) and late-life depression is well-documented. However, the role of resilience as a buffer against the adverse mental health effects of SLEs in late life has not been convincingly demonstrated. In this paper, the moderating effect of resilience in the relationship between SLEs and depressive symptomatology in older Chinese adults is investigated.

METHOD

A population sample of 385 community-dwelling older Chinese adults aged ≥60 years responded to questionnaires on resilience (Connor-Davidson resilience scale), depressive symptomatology (Geriatric Depression Scale, GDS-15) and SLEs.

RESULTS

Increased numbers of SLEs (β = 0.343, p < .001) and lower levels of resilience (β = -0.137, p < 0.001) were significantly associated with higher levels of depressive symptomatology. There was a significant interaction of resilience and number of SLEs on depressive symptomatology (p = 0.003). The sense of personal competence and optimism was the principal underlying resilience dimension moderating the relationship for both the young-old (aged 60-69) and the old-old (aged 70 and above).

CONCLUSION

The finding of significant interaction supported the role of resilience in moderating the adverse effect of SLEs in terms of depressive symptoms among older Chinese adults.

Cognitive performance and the course of depressive symptoms over 7 years of follow-up: the SMART-MR study

BACKGROUND

Depressive symptoms and cognitive impairment often co-occur, but their interactive relationship is complex and the direction of causation is still a topic of research. We examined the influence of cognitive performance on the course of depressive symptoms during 7 years of follow-up in patients with vascular disease.

METHOD

Within the SMART-MR study, 736 patients (mean age 62 ± 10 years) had neuropsychological assessment on four cognitive domains at baseline [memory (MEM), working memory (WMEM), executive functioning (EXEC), and information processing speed (SPEED)]. Depressive symptoms were assessed with the Patient Health Questionnaire-9 (PHQ-9) at baseline and every 6 months during 7 years of follow-up. Generalized Estimating Equation (GEE) models were used to assess the association between cognitive performance with depressive symptoms at multiple time points during follow-up. Interaction terms between the respective cognitive domains and time was included to examine if the course of depressive symptoms differed according to baseline cognitive performance.

RESULTS

The GEE analyses showed no significant interactions between the respective cognitive domains and time indicating no different course of depressive symptoms according to baseline cognitive performance. Lower MEM, EXEC or SPEED, but not WMEM performance, was significantly associated with more depressive symptoms during follow-up per z score decrease: MEM [B = 0.70, 95% confidence interval (CI) 0.35-1.05]; EXEC (B = 0.88, 95% CI 0.41-1.36), and SPEED (B = 0.57, 95% CI 0.21-0.92).

CONCLUSIONS

Poorer cognitive performance on the domains MEM, EXEC and SPEED, but not WMEM, was associated with higher levels of depressive symptoms over 7 years of follow-up, but not with a different course of depressive symptoms over time.

Neuroticism in Remitted Major Depression: Elevated with Early Onset but Not Late Onset of Depression

BACKGROUND

The personality trait of neuroticism is strongly related to depression, but depression is etiologically heterogeneous. Late-onset depression (LOD) may be more closely related to vascular factors, and previous studies of neuroticism in LOD versus early-onset depression (EOD) have not been consistent.

METHOD

We examined neuroticism, extraversion and perceived stress in 88 fully remitted depressed patients with a mean age of 60 years and with a history of hospitalization for major depressive disorder. Patients were divided into those with onset after and those with onset before 50 years of age (LOD and EOD, respectively), and the two groups were compared both with each other and with matched control groups of healthy subjects.

RESULTS

EOD patients showed increased levels of neuroticism in comparison with both LOD and matched controls, who did not differ. The association between age of onset and neuroticism was confirmed in analyses based on age of depression onset as a continuous variable.

CONCLUSION

Neuroticism may be an etiological factor in EOD but not or less so in LOD. This finding contributes to the growing evidence for etiological differences between early- and late-onset late-life depression.

Comorbidity of late-life depression in the United States: a population-based study

OBJECTIVES

This study sought to determine the clinical and sociodemographic correlates and the treatment-seeking rate of major depressive disorder (MDD), diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, among older adults and its association with comorbid psychiatric disorders and perceived health status.

METHODS

Data were drawn from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions, a large cross-sectional survey (N = 43,093) representative of the US population.

RESULTS

Compared with participants aged 65 years and older without a 12-month diagnosis of MDD, those with MDD were more likely to have lifetime and 12-month comorbid psychiatric disorders. Except for lifetime dysthymia, we found no significant interaction between rates of current somatic comorbidity, lifetime and 12-month psychiatric comorbidity, and age groups. Compared with younger participants with a 12-month MDD, they had an older age at onset, reported a similar number of lifetime major depressive episodes and perceived health status, and had lower mental health service utilization rates.

CONCLUSIONS

Current major depression in the elderly seems to be as disabling as in younger adults in terms of comorbid psychiatric disorders and impaired quality of life. Poorer prognosis of MDD in older adults might be explained by a lower perceived need of treatment, resulting in a lower rate of treatment-seeking behavior.

Factors associated with anxiety among elderly hypertensive in primary care setting

BACKGROUND

There is increasing evidence showing that anxiety is associated with morbidity in the older age group. Factors contributing to anxiety may vary among different diseases and settings.

AIMS

The aim of this study was to determine the factors associated with anxiety symptoms among elderly hypertensive at the primary care level.

METHODS

A cross-sectional study and face-to-face interviews using Hospital Anxiety and Depression Scale (HADS) were conducted among elderly hypertensive.

RESULTS

The mean (SD) age of subjects was 68.8 (6.76) years and comprised of 49.5% and 50.5% of males and females, respectively. The majority of respondents were Malays (76.1%), followed by Chinese (14.3%), and Indians (9.5%). The mean (SD) duration of hypertension was 8.44 (7.29) years and the prevalence of anxiety symptoms was 13.3% (95% CI: 9.9, 16.7). Multiple logistic regression analysis showed that elderly hypertensive with a past history of stroke (adjusted OR: 4.472; 95% CI: 1.754, 11.405; p = 0.002) and depression (adjusted OR: 3.715; 95% CI: 2.009, 6.872; p < 0.001) was significantly associated with the factors for anxiety.

CONCLUSION

Elderly hypertensive with a history of stroke and having depressive symptoms are susceptible to get the anxiety. Therefore, screenings of risk factors and early intervention may improve the quality of life among elderly.

Adverse Childhood and Recent Negative Life Events: Contrasting Associations With Cognitive Decline in Older Persons

OBJECTIVE

To examine whether persons who experienced adverse childhood events or recent negative life events have a worse cognitive performance and faster cognitive decline and the role of depression and apolipoprotein E-∊4 in this relationship.

METHODS

The community-based sample consisted of 10-year follow-up data of 1312 persons participating in the Longitudinal Aging Study Amsterdam (age range 65-85 years).

RESULTS

Persons who experienced adverse childhood events showed a faster 10-year decline in processing speed but only when depressive symptoms were experienced. Persons with more recent negative life events showed slower processing speed at baseline but no faster decline.

CONCLUSIONS

Childhood adversity may cause biological or psychological vulnerability, which is associated with both depressive symptoms and cognitive decline in later life. The accumulation of recent negative life events did not affect cognitive functioning over a longer time period.

Effectiveness and predictors of outcome in routine out-patient mental health care for older adults

ABSTRACT Background: Meta-analyses show efficacy of several psychological and pharmacological interventions for late-life psychiatric disorders, but generalization of effects to routine mental health care for older people remains unknown. Aim of this study is to investigate the improvement of functioning within one year of referral to an outpatient mental health clinic for older adults. Methods: Pre-post measurement of the Health of Nations Outcome Scale 65+ (HoNOS 65+) in 704 older people referred for psychiatric problems (no dementia) to any of the seven participating mental health care organizations. Results: The pre-post-test Cohen's d effect size was 1.08 in the total group and 1.23 in depressed patients, the largest subgroup. Linear regression identified better functioning at baseline, comorbid personality disorder, somatic comorbidity and life events during treatment as determinants of a worse outcome. Conclusions: Functioning of older persons with psychiatric problems largely improves after treatment in routine mental health care.

Anxiety symptoms in 74+ community-dwelling elderly: associations with physical morbidity, depression and alcohol consumption

Objective

Anxiety among community-dwelling older adults has not been studied sufficiently. The aims of this cross-sectional population-based study were to estimate the point prevalence of clinically relevant anxiety symptoms and to describe their socio-demographic and clinical features, with particular focus on the association with somatic illnesses.

Methods

Three-hundred-sixty-six non-demented older adults (mean age 83.7±6.2, range 74–99 years) from the Faenza Project (Northern Italy) were assessed using the Cambridge Mental Disorders of the Elderly Examination-Revised (CAMDEX-R) and the Geriatric Anxiety Inventory short form (GAI-sf). Multi-adjusted regression analyses were used to estimate Odds Ratio (OR) and 95% Confidence Intervals (95% CI).

Results

Clinically relevant anxiety symptoms occurred in one out of five participants (point prevalence 21.0%) and were significantly associated with depression (OR 5.6 per rank; 95% CI: 3.1–10.1), physical morbidity (OR 3.5 per illness; 95% CI: 1.0–11.9) and female gender (OR 2.8; 95% CI: 1.4–5.5). Further, there were significant associations with a consumption of alcohol exceeding 1 alcoholic unit/day.

Conclusions

Anxiety symptoms are very common in older subjects, especially when medically ill. Depression and alcohol consumption often co-occur with late-life anxiety symptoms, thus requiring special attention in daily clinical practice.

Clinical outcomes of older depressed patients with and without comorbid neuroticism

BACKGROUND

Neuroticism is a psychological construct that includes tendency to exhibit negative affect (NA), having poor stress tolerance and being at risk for depression and anxiety disorders. The consequences of neuroticism in the elderly adults are understudied. We hypothesized that older depressed patients with comorbid neuroticism at baseline would have worse mood and cognitive outcomes compared with older depressed patients without neuroticism.

METHODS

One hundred and ten older depressed adults completed baseline self-reports of depression and the NEO-Personality Inventory as a measure of neuroticism, were administered a battery of cognitive tests annually and were seen by a study psychiatrist who assessed patients using the Montgomery Åsberg Depression Rating Scale (MADRS) and treated patients with antidepressants using an established treatment guideline. Patients were followed as clinically indicated for up to three years. We measured remission (defined as MADRS score ≤ 6) rates at one year as a categorical outcome. In addition, we used Cox proportional hazard models to examine the relationship between neuroticism and change in MADRS and cognitive score over time.

RESULTS

Non-remitters (30%) at one year had higher scores in total neuroticism (TN), vulnerability to stress (VS), and NA. Over three years, time to achieve remission was associated with higher TN, higher VS, and greater NA. In analyses controlling for baseline cognitive score, age, sex, and education, VS was associated with baseline to two-year change in cognition.

CONCLUSIONS

Presence of neuroticism in older depressed patients treated with medication is associated with poor mood outcomes and may indicate increased risk of cognitive decline.

Stressful life events and neuroticism as predictors of late-life versus early-life depression

BACKGROUND

The occurrence of depression in younger adults is related to the combination of long-standing factors such as personality traits (neuroticism) and more acute factors such as the subjective impact of stressful life events. Whether an increase in physical illnesses changes these associations in old age depression remains a matter of debate.

METHODS

We compared 79 outpatients with major depression and 102 never-depressed controls; subjects included both young (mean age: 35 years) and older (mean age: 70 years) adults. Assessments included the Social Readjustment Rating Scale, NEO Personality Inventory and Cumulative Illness Rating Scale. Logistic regression models analyzed the association between depression and subjective impact of stressful life events while controlling for neuroticism and physical illness.

RESULTS

Patients and controls experienced the same number of stressful life events in the past 12 months. However, in contrast to the controls, patients associated the events with a subjective negative emotional impact. Negative stress impact and levels of neuroticism, but not physical illness, significantly predicted depression in young age. In old age, negative stress impact was weakly associated with depression. In this age group, depressive illness was also determined by physical illness burden and neuroticism.

CONCLUSIONS

Our data suggest that the subjective impact of life stressors, although rated as of the same magnitude, plays a less important role in accounting for depression in older age compared to young age. They also indicate an increasing weight of physical illness burden in the prediction of depression occurrence in old age.

What are the causes of late-life depression?

Although depression in old age is less common than depression in younger populations, it still affects more than 1 million community-living older adults. Depression in late life has been associated with reduced quality of life and increased mortality from both suicide and illness. Its causes are multifactorial but are prominently related to both biologic and social factors. Psychological factors, although less studied in elders, are also important in understanding its cause. In this article, multiple facets of late-life depression are reviewed, including its clinical presentation, epidemiology, and biopsychosocial causes.

A prospective study of the bi-directional association between vision loss and depression in the elderly

BACKGROUND

Increasing visual impairment (VI) with age has been associated with mental health problems but the question of temporal direction and reverse causality has not been addressed previously. Our objective was to prospectively examine the bi-directional association of VI and visual function (VF) loss with depressive symptoms in the elderly.

METHODS

The cohort comprised 4216 participants (40.2% men) aged 65 and over with 10 years of follow-up. Near VI was defined using measured usual-corrected binocular acuity while distance VF was self-declared. Participants having a major depressive episode or a Center for Epidemiologic Studies Depression Scale score ≥ 16 were classified as having depressive symptomatology. Longitudinal analyses used mixed logistic models for repeated evaluations.

RESULTS

After adjustment for demographic factors, participants with moderate to severe near VI at baseline had increased odds of developing depressive symptomatology (Odds Ratio [OR]=1.60; 95% Confidence Interval [CI]=1.08-2.38), but after multiple adjustments the association fell below the significance level. A 2-year decrease in distance VF was associated with increased odds of depressive symptomatology during follow-up after multiple adjustments (OR=3.03; 95% CI=1.75-5.23). Baseline depressive symptomatology was not associated with incident near VI but was associated with VF loss after multivariate adjustment (OR=1.62; 95% CI=1.15-2.28).

LIMITATIONS

The causes of VI have not been recorded.

CONCLUSIONS

The relation of vision loss to onset of depressive symptomatology differs according to near VI or distance VF and declines across time. A reverse strong association was found between baseline depression and incident loss of distance VF suggesting a downward spiral of events.

Do negative affect characteristics and subjective memory concerns increase risk for late life anxiety?

To better understand the development and exacerbation of late-life anxiety, we tested a risk model positing that trait negative affect (NA) characteristics would interact with cognitive functioning, thereby increasing some older adults' risk for increased anxiety symptoms. The moderator-mediator model consisted of measures of NA, cognitive functioning, and their interaction, as predictors of later Hamilton Anxiety Rating Scale scores (HARS) via a mediational process, subjective memory concerns (SMCs). Older adults (aged 65-years and over; M(age)=76.7 years, SD=6.90 years) completed evaluations four times over approximately 18 months. A latent growth curve model including Anxiety Sensitivity Index total score (ASI), Mattis Dementia Rating Scale-2 (DRS) total raw score, the ASI×DRS interaction, a SMC measure as mediator, HARS intercept (scores at times 3 and 4), and HARS slope provided good fit. The ASI×DRS-2 interaction at Time 1 predicted HARS slope score (β=-.34, p<.05). When ASI score was high, stronger cognitive functioning was associated with fewer anxiety symptoms. The indirect effect of ASI score predicting HARS score 18-months later through the SMC mediator was statistically significant (β=.08, p<.05). Results suggest that the cognitive functioning changes associated with aging might contribute to the development of anxiety symptoms in older adults with specific NA traits. Implications for predicting and preventing late life anxiety disorders are discussed.

Mental health care Monitor Older adults (MEMO): monitoring patient characteristics and outcome in Dutch mental health services for older adults

Information on which older adults attend mental health care and whether they profit from the care they receive is important for policy-makers. To assess this information in daily practice, the "Mental health care Monitor Older adults" (MEMO) was developed in the Netherlands. The aim of this paper is to describe MEMO and the older adults who attend outpatient mental health care regarding their predisposing and enabling characteristics and need for care. In MEMO all patients referred to the division of old age psychiatry of the participating mental health care organisations are assessed at baseline and monitored at 4, 8 and 12-month follow-up. Primary outcomes are mental and social functioning, consumer satisfaction, and type of treatment provided (MEMO Basic). Over the years, MEMO Basic is repeated. In each cycle, additional information on specific patient groups is added (e.g. mood disorders). Data collection is supported by a web-based system for clinicians, including direct feedback to monitor patients throughout treatment. First results at baseline showed that the majority of patients that entered the division of old age psychiatry was female (69%), had low education (83%), lived alone (53%), was depressed (42%) and had a comorbid condition (82%). It seemed that older immigrants were not sufficiently reached. The current study is the first in the Netherlands to evaluate patient characteristics and outcome in mental health care provided for older adults in day-to-day practice. If MEMO works out successfully, the method should be extended to other target groups.

Is there a bidirectional relationship between depressive symptoms and cognitive ability in older people? A prospective study using the English Longitudinal Study of Ageing

BACKGROUND

Cross-sectional surveys of older people commonly find associations between higher levels of depressive symptoms and poorer cognitive performance, but the direction of effect is unclear. We examined whether there was a bidirectional relationship between depressive symptoms and general cognitive ability in non-demented older people, and explored the role of physical health, smoking, exercise, social class and education as potential confounders of this association and as possible determinants of the rate of change of cognitive decline and depressive symptoms.

METHOD

The English Longitudinal Study of Ageing consists of people aged 50 years and over. Cognitive function and self-reported depressive symptoms were measured in 2002-2003, 2004-2005, 2006-2007 and 2008-2009. We fitted linear piecewise models with fixed knot positions to allow different slopes for different age groups. Analyses are based on 8611 people.

RESULTS

Mean cognitive function declined with age; there was no trend in the trajectory of depressive symptoms. Better cognitive function was associated with less depression up to the age of 80 years. Greater depression was associated with a slightly faster rate of cognitive decline but only in people aged 60-80 years. There were no consistent associations across age groups between sex, smoking, education, social class, exercise or number of chronic physical illnesses and the rate of change of cognitive decline or depressive symptoms.

CONCLUSIONS

In this longitudinal study of older people, there was no consistent evidence that being more depressed led to an acceleration in cognitive decline and no support for the hypothesis that there might be reciprocal dynamic influences between cognitive ability and depressive symptoms.

Age and risk for depression among the elderly: a meta-analysis of the published literature

OBJECTIVE

The goal of this study was to determine the relationship between age and risk for depression among the old and the oldest old. Method MEDLINE, EMBASE, and the Cochrane Library database were used to identify potential studies. The studies were divided into cross-sectional and longitudinal subsets. For each study, the numbers of the total participants, cases (for cross-sectional study), or incident cases (for longitudinal study) of depression in each age group were extracted and entered into Review Manager 4.2 software. Qualitative meta-analyses of cross-sectional studies and of longitudinal studies were performed. For prevalence and incidence rates of depression, odds risk (OR) and relative risk (RR) were calculated, respectively.

RESULTS

The qualitative meta-analyses showed that, compared with younger participants (above vs. below 65 years, above vs. below 70 years, above vs. below 75 years, and above vs. below 80 years), older age groups had a significantly higher risk for depression. (All of the ORs and RRs were significant.) Compared with participants aged 55-89, those aged above 90 years had no higher risk for depression. (Neither the OR nor the RR was significant.)

CONCLUSIONS

Despite the methodological limitations of this meta-analysis, older age appears to be an important risk factor for depression in the general elderly population (aged below 80 years), but not in the oldest population (aged above 85 years).

Characterizing the psychological distress response before and after a cancer diagnosis

Psychological distress among cancer survivors is common. It is unknown if symptoms predate diagnosis or differ from patients without cancer because studies are limited to patient follow-up. Linked cohort (Wisconsin Longitudinal Study) and tumor registry records were used to assess the psychological distress response pre- to post-cancer diagnosis. Adjusted predicted probabilities of being in one of five categories of change for three psychological distress measures (depression, anxiety, well-being) were compared for participants diagnosed with cancer between 1993-1994 and 2004-2005 and participants without cancer (N = 5,162). Cancer survivors were more likely to experience clinically significant increases (≥0.8 standard deviation) in depression (15, 95 % CI = 12-18 %) and anxiety (19 %, CI = 16-22 %) compared to their no-cancer counterparts (10 %, CI = 10-11 %; 11 %, CI = 11-12 %). Cancer survivors <5 years from diagnosis were more likely to experience worsening depression. Survivors ≥5 years were more likely to experience worsening anxiety. No significant results were found for well-being. Characterizing the psychological distress response is a prerequisite for identifying at-risk patients and communicating expected symptoms, allowing for proactive resource provision.

Anxiety disorders in older people

This article reviews the research into anxiety disorders in adults aged 65 years and older that has been published over the past ten years. The topics covered include: the construct of anxiety and its disorders in this age group; epidemiology, including prevalence, incidence, course, outlook, and risk factors; assessment scales; co-morbidity and differential diagnosis (depression, dementia, physical illness); and management, both pharmacological and non-pharmacological. There has been a significant improvement in our understanding of these disorders in older adults over this period, but evidence to support their treatment and prevention is still quite sparse.

What contributes to perceived stress in later life? A recursive partitioning approach

One possible explanation for the individual differences in outcomes of stress is the diversity of inputs that produce perceptions of being stressed. The current study examines how combinations of contextual features (e.g., social isolation, neighborhood quality, health problems, age discrimination, financial concerns, and recent life events) of later life contribute to overall feelings of stress. Recursive partitioning techniques (regression trees and random forests) were used to examine unique interrelations between predictors of perceived stress in a sample of 282 community-dwelling adults. Trees provided possible examples of equifinality (i.e., subsets of people with similar levels of perceived stress but different predictors) as well as identification both of contextual combinations that separated participants with very high and very low perceived stress. Random forest analyses aggregated across many trees based on permuted versions of the data and predictors; loneliness, financial strain, neighborhood strain, ageism, and to some extent life events emerged as important predictors. Interviews with a subsample of participants provided both thick description of the complex relationships identified in the trees, as well as additional risks not appearing in the survey results. Together, the analyses highlight what may be missed when stress is used as a simple unidimensional construct and can guide differential intervention efforts.

Factors associated with symptoms of anxiety and depression in five cohorts of community-based older people: the HALCyon (Healthy Ageing across the Life Course) Programme

BACKGROUND

Symptoms of anxiety and depression are common in older people, but the relative importance of factors operating in early and later life in influencing risk is unclear, particularly in the case of anxiety.

METHOD

We used data from five cohorts in the Healthy Ageing across the Life Course (HALCyon) collaborative research programme: the Aberdeen Birth Cohort 1936, the Caerphilly Prospective Study, the Hertfordshire Ageing Study, the Hertfordshire Cohort Study and the Lothian Birth Cohort 1921. We used logistic regression to examine the relationship between factors from early and later life and risk of anxiety or depression, defined as scores of 8 or more on the subscales of the Hospital Anxiety and Depression Scale, and meta-analysis to obtain an overall estimate of the effect of each.

RESULTS

Greater neuroticism, poorer cognitive or physical function, greater disability and taking more medications were associated in cross-sectional analyses with an increased overall likelihood of anxiety or depression. Associations between lower social class, either in childhood or currently, history of heart disease, stroke or diabetes and increased risk of anxiety or depression were attenuated and no longer statistically significant after adjustment for potential confounding or mediating variables. There was no association between birth weight and anxiety or depression in later life.

CONCLUSIONS

Anxiety and depression in later life are both strongly linked to personality, cognitive and physical function, disability and state of health, measured concurrently. Possible mechanisms that might underlie these associations are discussed.

Impact of Morbidity and Life Events on Successful Aging

The purpose of this study was to examine the risks of the incidence of chronic conditions and life events on successful aging. Longitudinal data from a 10-year follow-up health survey were used. Successful aging indicators included basic and advanced physical function, depressive symptoms, cognitive function, emotional support, participation in productive activities, and life satisfaction. The stressors included life events and morbidity years of 10 chronic conditions. Loss of offspring increased the risk to physical health, psychological health, and life satisfaction. Being newly widowed was related to depressive symptoms, whereas being newly divorced increased the risk of poor social support. Morbidity years increased the risk of failure in successful aging, especially for stroke, respiratory system disease, diabetes, and cancer. Emotional health of the elderly should be carefully monitored after onset of life events and incidences of chronic conditions.

Wishes to Die in Older People

Background: Death thoughts and wishes occur frequently among older people. In different European countries estimates of 10%–20% have been found. Aims: To determine the prevalence and associated factors of death thoughts and wishes among older people in The Netherlands. Methods: In The Netherlands 1794 people (58–98 years) were interviewed in 2005/2006 (Longitudinal Aging Study Amsterdam). Results: 81.3% reported never having death thoughts/wishes; 15.3% reported having had such thoughts/wishes; 3.4% reported currently having a wish to die and/or a weakened wish to continue living. Of those with a current wish to die, 67% had depressive symptoms (vs. 32% of people with death thoughts/wishes ever and 9% of people who never had had death thoughts/wishes), and 20% suffered from a depressive disorder (vs. 5% if death thoughts/wishes ever; 0.3% if never death thoughts/wishes). In a multivariate analysis, a current wish to die was associated with having depressive symptoms, a depressive disorder, lower perceived mastery, financial problems, loneliness, small network, involuntary urine loss, being divorced, and having a speech impediment. Conclusions: Practical implications for health-care professionals are that they should be aware that in certain situations older people are more likely to develop a wish to die, and that a wish to die does not necessarily mean that someone has a depressive disorder. Nevertheless, it should serve as a trigger to investigate and to treat depression if present.

Early and late life events and salivary cortisol in older persons

BACKGROUND

It has been hypothesized that stressful life events are associated with changes in hypothalamic-pituitary-adrenal (HPA) axis regulation, which increases susceptibility to psychiatric disorders. We investigated the association of early and late life events with HPA axis regulation in older persons.

METHOD

Within the Longitudinal Aging Study Amsterdam (LASA) 1055 participants (47% male), aged 63-93 years, collected saliva within 30 min after waking and late in the evening. Early and late life events were assessed during a home interview. The associations between life events and cortisol levels were examined using linear regression and analysis of covariance with adjustments for demographics, cardiovascular risk factors and depressive symptoms.

RESULTS

Within our sample, the median morning and evening cortisol levels were 15.0 nmol/l [interdecile range (10-90%): 7.4-27.0 nmol/l] and 2.8 nmol/l (10-90%: 1.5-6.3 nmol/l), respectively. Persons who reported early life events showed lower levels of natural log-transformed morning cortisol [B=-0.10, 95% confidence interval (CI) -0.17 to -0.04] and flattened diurnal variability of cortisol (B=-1.06, 95% CI -2.05 to -0.08). Those reporting two or more late life events showed higher levels of natural log-transformed morning cortisol (B=0.10, 95% CI 0.02-0.18) and higher diurnal variability (B=1.19, 95% CI 0.05-2.33). No associations were found with evening cortisol.

CONCLUSIONS

The results of this large population-based study of older persons suggest a differential association of early and late life events with HPA axis regulation; early life events were associated with a relative hypo-secretion of morning cortisol and flattened diurnal variability, while late life events were associated with elevated secretion of morning cortisol and high diurnal variability of cortisol.

Identifying patterns in cortisol secretion in an older population. Findings from the Whitehall II study

Alterations in the patterning of diurnal cortisol secretion are associated with poor health in clinical populations with 'flat' patterns a particular risk. Flatter patterns in cortisol secretion may reflect impaired negative feedback in the hypothalamic-pituitary-adrenal axis. The correlates of discrete clusters of patterns in the diurnal secretion of cortisol have not been well described in large community dwelling populations. We describe discrete clusters of patterns of cortisol secretion and examine the correlates of these patterns using a latent variable mixture modelling approach. Analyses use data from 2802 participants with complete information on cortisol secretion, age, walking/gait speed, stress, waking up time and sleep duration. Cortisol was assessed from six saliva samples collected at waking, waking plus 30 min, 2.5h, 8h, 12h and bedtime. We find two patterns ("curves") of diurnal cortisol secretion. These curves are described as 'normative' [prevalence 73%] and a 'raised' [27%] curve differentiated by a lower cortisol awakening response in the normative group, a higher diurnal cortisol and 'flatter' pattern of release in the raised group. Older age, being male, a smoker, stress on the day of sampling, slower walking speed and shorter sleep duration increased the odds of being in the raised curve, relative to the normative curve. In conclusion, two patterns of cortisol secretion occur in middle aged men and women. Raised pattern of secretion, which occurs in 27% of our participants is associated with demographic variables, adverse health behaviours, psychosocial environment and impaired physical functioning.

Chronic diseases and risk for depression in old age: a meta-analysis of published literature

OBJECTIVE

We assessed the relationship between chronic diseases and risk for depression in old age.

METHOD

MEDLINE, EMBASE, The Cochrane Library database were used to identify potential studies. All of the clinical studies that obtained data on the association between chronic diseases and risk of depression among individuals aged 55 years or older were identified and included in this review. The studies were classified into cross-sectional and longitudinal subsets. The quantitative meta-analysis of cross-sectional studies and that of longitudinal studies were preformed, respectively. For prevalence and incidence rates of depression, odds risk (OR) and relative risk (RR) were calculated, respectively.

RESULTS

Since all but one study found in the search was for individuals 60 years of age or over, we assessed and report on results for this larger group only. 24 cross-sectional and 7 prospective longitudinal studies were included in this review. The quantitative meta-analysis showed that, among chronic diseases, stroke, loss of hearing, loss of vision, cardiac disease or chronic lung disease had both a significant OR and RR for increased depression in old age; arthritis, hypertension or diabetes had a significant OR but an un-significant RR for increased depression in old age; and gastrointestinal disease had neither a significant OR nor a significant RR for increased depression in old age.

CONCLUSIONS

We concluded here that in old age, the associations of depression with some chronic diseases were definite; among these chronic diseases, stroke, loss of hearing, loss of vision, cardiac disease and chronic lung disease were risk factors for increased depression, but it should be further investigated whether arthritis, hypertension and diabetes were risk factors for increased depression or not.

Prescribing antidepressants and benzodiazepines in the Netherlands: is chronic physical illness involved?

In this study we assessed differences in new and repeat prescriptions of psycho-tropics between patients receiving prescriptions for drugs to treat a common chronic disease and people without such prescriptions. The study used the databases of two Dutch health insurance companies (3 million people). We selected all Dutch men and women aged 45 and older who were registered for six consecutive years (1999-2004). Our analyses both found a consistent relation between psycho-tropics on the one hand and physical illness on the other. People with multi-morbidity were prescribed these drugs most often, especially men and those younger than 65. Epidemiological studies showed a prevalence of depression among people with multi-morbidity to be twice as high as among people without such conditions. According to recent guidelines non-drug treatment may be the first therapy option for patients with non severe depression. If prescribed for a long time, benzodiazepine prescriptions are especially known to be addictive. Our data raise the question to what extent patients with a chronic physical disease suffering from co-occurring mental problems are prescribed psycho-tropics in accord with the guidelines that also advise mental support in case of non severe mental problems. Further research can answer this important question.

Health status and risk for depression among the elderly: a meta-analysis of published literature

OBJECTIVE

the goal of this study was to determine the relationship between health status, including self-rated health status and chronic disease, and risk for depression among the elderly.

METHOD

MEDLINE, EMBASE and The Cochrane Library Database were used to identify potential studies. The studies were classified into cross-sectional and longitudinal subsets. For each study, the numbers of the total participants, cases (for cross-sectional study) or incident cases (for longitudinal study) of depression in each health status group were extracted and entered into Review Manager 4.2. The quantitative meta-analysis of cross-sectional studies and that of longitudinal studies were performed, respectively. For prevalence and incidence rates of depression, odds risk and relative risk (RR) were calculated, respectively.

RESULTS

the quantitative meta-analysis showed that, compared with the elderly without chronic disease, those with chronic disease had higher risk for depression (RR: 1.53, 95% confidence intervals (CI): 1.20-1.97). Compared with the elderly with good self-rated health, those with poor self-rated health had higher risk for depression (RR: 2.40, 95% CI: 1.94-2.97).

CONCLUSIONS

despite the methodological limitations of this meta-analysis, both poor self-rated health status and the presence of chronic disease are risk factors for depression among the elderly. In the elderly, poor self-reported health status appears to be more strongly associated with depression than the presence of chronic disease.
