Prevalence of dynapenia and overlap with disability, depression, and executive dysfunction

OBJECTIVE

This study aims to investigate handgrip strength and dynapenia prevalence among older adults stratified by Brazilian macroregions. Additionally, we aim to evaluate the overlap between dynapenia and Instrumental Activities of Daily Living (IADL) disability, depression, and executive dysfunction on a national basis and by each Brazilian macroregion.

METHODS

This cross-sectional analysis was based on data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). A multistage cluster sample design was used, with a representative population-based study of non-institutionalized community-dwelling Brazilians aged ≥ 50 years from 70 municipalities across all five macroregions of the country. The outcome variable was dynapenia. Covariables were IADL disability, depression, and executive dysfunction. The Brazilian macroregions were used for stratification. In addition, the following additional variables were included: age group, gender, education level, macroregions (North, Northeast, Southeast, South, and Midwest), self-reported health, multimorbidity, and falls.

RESULTS

A total of 8,849 (94%) of the sample provided complete information for the handgrip strength assessment and were included in this analysis. Dynapenia prevalence was higher in North and Northeast regions (28.5% and 35.1%, respectively). We identified statistically significant differences between different macroregions for dynapenia, IADL disability, and verbal fluency, with worse values in the North and Northeast regions. In the North and Northeast macroregions, nearly half of the subjects that presented executive dysfunction and IADL disability also had dynapenia. There was a more significant overlap in the prevalence of all four conditions in the North and Northeast regions (4.8% and 5.5%, respectively), whereas the overlap was smaller in the South (2.3%). There was also a smaller overlap in the prevalence of dynapenia and depression in the South (5.8%) compared with other macroregions.

CONCLUSIONS

Macroregions in Brazil exhibit marked differences in the prevalence of dynapenia and in its overlap with IADL disability, depression, and executive dysfunction.

The impact of women's off-farm employment on depressive symptoms: Evidence from rural China

While China's economy has grown rapidly in recent decades, urban-rural inequalities in mental health have persisted, and depression is more prevalent among rural women. Using a nationally-representative survey data in China, this paper investigates the impact of women's off-farm employment on their depressive symptoms. Results from instrumental variable and individual fixed effects estimation show that women's participation in off-farm employment leads to a significant reduction in depressive symptoms. We further take into account the confounding effects of working conditions, and the main results are robust. Moreover, off-farm employment enhances women's mental health mainly through pathways including increased absolute income, higher self-perceived relative income, more frequent healthy behaviors, increased likelihood of health investment, and obtaining more formal social support. Further evidence suggests that the depression-reducing effect of off-farm employment is more effective for those with more severe depressive symptoms, middle-aged and elderly persons, and women with lower body mass index. The findings have important implications for preventing depressive disorders and improving mental health in China and other developing countries.

Effects of an internet-delivered insomnia intervention for older adults: A secondary analysis on symptoms of depression and anxiety

Objective

To test whether an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) program for older adults attenuates symptoms of depression and anxiety.

Methods

Adults aged ≥ 55 with insomnia were randomized to SHUTi-OASIS (Sleep Healthy Using the Internet for Older Adult Sufferers of Insomnia and Sleeplessness; N = 207) or Patient Education (PE; N = 104). Depression and anxiety were assessed (HADS-D and HADS-A, respectively) at baseline, post-assessment, and 6- and 12-month follow-ups.

Results

Multilevel modeling of HADS-D showed a condition by time interaction (F[3,779] = 3.23, p = .02): SHUTi-OASIS participants reported lower symptoms than PE at post-assessment. There was no such interaction effect for HADS-A (F[3,779] = 2.12, p = .10). Generalized linear modeling showed no moderation of effects by baseline symptom severity.

Conclusions

Participants randomized to Internet-delivered CBT-I showed stable depression and anxiety across time, while control participants’ depressive symptoms briefly increased. CBT-I may help prevent development or worsening of psychological distress among older adults with insomnia.

Bidirectional associations of vision loss, hearing loss, and dual sensory loss with depressive symptoms among the middle-aged and older adults in China

BACKGROUND

Most studies on the relationship between sensory loss and depression focus on the unidirectional association between sensory loss and the risk of depression based on cross-sectional designs. The present study aimed to explore the bidirectional longitudinal associations of vison loss (VL), ¹ hearing loss (HL), ² and dual sensory loss (DSL)³ with depressive symptoms among Chinese population.

METHODS

A longitudinal study was conducted among 13,690 participants aged 45 years and older over four years. VL, HL, and DSL were identified through self-reporting, and depressive symptoms were assessed using a 10-item Center for Epidemiologic Studies Depression Scale. Multivariable Cox proportional hazards regression models were constructed to estimate the bidirectional associations of VL, HL, and DSL with depressive symptoms.

RESULTS

Participants with self-reported VL (HR: 1.14, 95%CI: 1.04-1.24), HL (HR: 1.22, 95%CI: 1.07-1.37), and DSL (HR: 1.27, 95%CI: 1.08-1.49) were associated with higher risk of developing depressive symptoms, compared with those without VL, HL, and DSL, respectively. In comparison with those without depressive symptoms, participants with depressive symptoms in the baseline had higher risk of developing VL (HR: 1.43, 95%CI: 1.33-1.54), HL (HR: 1.49, 95%CI: 1.36-1.63), and DSL (HR: 1.76, 95%CI: 1.59-1.95).

LIMITATIONS

Sensory loss was defined only based on participants' self-report.

CONCLUSIONS

Significant bidirectional associations exist between self-reported VL, HL, or DSL and depressive symptoms. The mental health of people with VL and HL should be focused on, and regular assessments of vision and hearing in people with depressive symptoms are recommended.

Chronic Conditions, Persistent Pain, and Psychological Distress Among the Rural Older Adults: A Path Analysis in Shandong, China

Psychological distress were found to be associated with chronic conditions and persistent pain. However, few studies explored the underlying pathways between them. This study aimed to analyze the path of chronic conditions and persistent pain on psychological distress through sleep quality and self-rated health. A total of 2,748 rural older people in Shandong, China were included in this study. Path analysis was performed by using Mplus 8.3 to examine the associations between chronic conditions, persistent pain, sleep quality, self-rated health, and psychological distress after adjusting for age, gender, education, and household income. The prevalence of psychological distress among the older adults in this study was 47.49%. Chronic conditions and persistent pain were indirectly associated with psychological distress through six mediating pathways: (1) the path from chronic conditions to psychological distress through sleep quality (β = 0.041, 95%CI: 0.015-0.067) and self-rated health (β = 0.064, 95%CI: 0.038-0.091), respectively, and a chain mediation existed (β = 0.007, 95% CI: 0.000-0.014); (2) the path of persistent pain and psychological distress through sleep quality (β = 0.058, 95% CI: 0.014-0.102) and self-rated health (β = 0.048, 95% CI: 0.000-0.096), respectively, also the chain mediation found (β = 0.009, 95% CI: 0.005-0.014). Psychological distress was associated with chronic conditions and persistent pain through decreased sleep quality and self-rated health among Chinese rural older people. Multi-pronged targeted intervention should be taken for older adults with chronic conditions and persistent pain.

Association of Hearing Loss With Psychological Distress and Utilization of Mental Health Services Among Adults in the United States

IMPORTANCE

Psychological distress affects health and health care utilization. Hearing loss (HL) is highly prevalent and undertreated, and it may be a potentially modifiable risk factor for psychological distress.

OBJECTIVE

To investigate the association between HL, psychological distress, and mental health care utilization among adults in the United States.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included 25 665 individuals aged 18 years and older who participated in the 2017 National Health Interview Survey, a home-based nationally representative cross-sectional survey of noninstitutionalized US adults conducted by trained interviewers.

EXPOSURES

Self-reported hearing and hearing aid use.

MAIN OUTCOMES AND MEASURES

Kessler psychological distress scale (scores ≥5 indicating moderate distress), self-reported use of medication to treat depression or anxiety symptoms, and use of mental health services in the past year.

RESULTS

A total of 25 665 adults (mean [SD] age 47.0 [18.1] years, 51.7% [95% CI, 51.0%-52.5%] women, weighted to be representative of the US adult population) were included in the analysis. Compared with 11 558 participants (49.3%; 95% CI, 48.2%-50.5%) with no HL, the 9390 (35.3%; 95% CI, 34.4%-36.2%) with mild HL and 4717 (15.4%; 95% CI, 14.8%-16.0%) with moderate or worse HL had increased odds of moderate psychological distress (mild HL: odds ratio [OR], 1.49; 95% CI, 1.35-1.62; moderate HL: OR, 2.12; 95% CI, 1.87-2.41) and were more likely to report antidepressant medication use (mild HL: OR, 1.39; 95% CI, 1.17-1.67; moderate HL: OR, 2.07; 95% CI, 1.70-2.57), and antianxiety medication use (mild HL: OR, 1.39; 95% CI, 1.16-1.67; moderate HL: OR, 1.94; 95% CI, 1.57-2.39). Moderate HL was associated with increased odds of use of mental health services (moderate HL: OR, 1.53; 95% CI, 1.30-1.79). Among individuals with moderate HL, those with hearing aids (1066 [22.6%]) were less likely to experience psychological distress than those without hearing aids (3651 [77.4%]; OR, 0.66; 95% CI, 0.53-0.83).

CONCLUSIONS AND RELEVANCE

In a large nationally representative sample of US adults, self-reported HL was associated with both greater psychological distress and increased rates of antidepressant and antianxiety medication use and utilization of mental health services. Further research is needed to investigate whether HL may be a modifiable risk factor for these outcomes.

Age and sex differences in hearing loss association with depressive symptoms: analyses of NHANES 2011-2012

BACKGROUND

Depression is a common and significant health problem. Hearing loss is the third most common chronic physical condition in the USA and might be a factor in depression. To determine whether hearing loss is associated with depressive symptoms in US adults ages 20-69 years.

METHODS

National Health and Nutrition Examination Survey (NHANES) data (2011-2012) were used to assess the potential relationship between hearing loss and depression, in adults (20-69 years) who answered the Patient Health Questionnaire (PHQ-9) depression screening module, with pure tone audiometry measurements, and complete information on the co-variates data (n = 3316). The degree of speech-frequency hearing loss (SFHL) and high-frequency hearing loss (HFHL) were defined as slight/mild hearing loss ⩾26-40 dB; moderate/worse hearing loss ⩾41 dB by pure tone audiometry examination.

RESULTS

Moderate/worse HFHL was statistically significantly associated with depressive symptoms (OR 1.54, 95% CL 1.04-2.27) when the analyses were conducted among all participants. Further stratification by gender and age groups found that moderate/worse HFHL (OR 3.85, 95% CL 1.39-10.65) and moderate/worse SFHL (OR 5.75, 95% CL 1.46-22.71) were associated with depressive symptoms in women ages 52-69 years.

CONCLUSIONS

Moderate/worse speech frequency and HFHL are associated with depression in women ages 52-69 years, independent of other risk factors. Hearing screenings are likely to reduce delays in diagnosis and provide early opportunities for noise prevention counseling and access to hearing aids. Health professionals should be aware of depressive signs and symptoms in patients with hearing loss.

Hearing Loss and Depression in Older Adults: A Systematic Review and Meta-analysis

Background and Objectives

Studies reporting an association between hearing loss and depression in older adults are conflicting and warrant a systematic review and meta-analysis of the evidence.

Research Design and Methods

A search of academic databases (e.g., MEDLINE) and gray literature (e.g., OpenGrey) identified relevant articles published up to July 17, 2018. Cross-sectional or cohort designs were included. Outcome effects were computed as odds ratios (ORs) and pooled using random-effects meta-analysis (PROSPERO: CRD42018084494).

Results

A total of 147,148 participants from 35 studies met inclusion criteria. Twenty-four studies were cross-sectional and 11 were cohort designs. Overall, hearing loss was associated with statistically significantly greater odds of depression in older adults (OR = 1.47, 95% confidence interval [CI] = 1.31−1.65). When studies were stratified by design, hearing loss was associated with greater odds of depression in cross-sectional studies (OR = 1.54, 95% CI = 1.31−1.80) and cohort studies (OR = 1.39, 95% CI = 1.16 − 1.67), and there was no difference between cross-sectional or cohort effect estimates (Q = 0.64, p = .42). There was no effect of moderator variables (i.e., hearing aid use) on the association between hearing loss and depression, but these findings must be interpreted with caution. There was no presence of publication bias but certainty in the estimation of the overall effect was classified as “low.”

Discussion and Implications

Older adults may experience increased odds of depression associated with hearing loss, and this association may not be influenced by study or participant characteristics.

Race/skin color and mental health disorders in Brazil: a systematic review of the literature

Mental health disorders contribute a significant burden to society. This systematic literature review aims to summarize the current state of the literature on race/skin color and mental health disorders in Brazil.

METHODS

PubMed and Lilacs were searched using descriptors for mental health disorders (depression, anxiety, Common Mental Disorders, psychiatric morbidity, etc.) and race to find studies conducted in Brazil. Studies of non-population groups, that did not analyze race/skin color, or for which the mental disorder was not the object of study were excluded. After evaluation of quality, 14 articles were selected for inclusion. There was an overall higher prevalence of mental health disorders in non-Whites. Of the six multivariate analyses that found statistically significant results, five indicated a greater prevalence or odds of mental health disorder in non-Whites compared to Whites (measure of association between 1.18-1.85). This review identified the trend in the literature regarding the association between race and mental health disorders. However, important difficulties complicate the comparability of the studies, principally in function of the differences in the mental health disorders studied, the method of categorizing race/skin color, and the screening tools used in the studies analyzed.

Prevalence of geriatric depression in a community sample in Ghana: Analysis of associated risk and protective factors

BACKGROUND

Ageing comes with its own associated physical and psychosocial challenges. Depression is reported as one of the most prevalent psychopathology found among elderly people. However, there is dearth of literature in Ghana regarding mental health and its associated risk and protective factors among Ghanaians who are aged 65years and above. This study examined the prevalence and factors associated with depression among the aged in Ghana.

METHODS

A cross-sectional survey design was employed and a total of 262 elderly people (65+years) were sampled. The Geriatric Depression Scale, Brief COPE and demographic questionnaires were administered to the participants.

RESULTS

There was 37.8% prevalence of depression among the participants. Socio-demographic characteristics such as religion, living status and presence of chronic illness independently predicted depression among the participants. The use of religion, acceptance and active coping were the most commonly reported coping strategies among the participants while denial, behavioural disengagement and substance use were the least used coping strategies among the participants. The use of active coping predicted decreased depression levels whereas the use of behavioural disengagement and self-blame significantly predicted increased depression levels among the participants.

CONCLUSIONS

Depression is a major challenge among the aged in this study and therefore, mental health screening should form part of the routine health screening practices for the elderly. The findings call for interventions aimed at promoting healthy ageing among the elderly in Ghana.

Multimorbidity and depression: A systematic review and meta-analysis

BACKGROUND

Multimorbidity, the presence of two or more chronic conditions, is increasingly common and complicates the assessment and management of depression. The aim was to investigate the relationship between multimorbidity and depression.

METHOD

A systematic literature search was conducted using the databases; PsychINFO, Medline, Embase, CINAHL and Cochrane Central. Results were meta-analysed to determine risk for a depressive disorder or depressive symptoms in people with multimorbidity.

RESULTS

Forty articles were identified as eligible (n = 381527). The risk for depressive disorder was twice as great for people with multimorbidity compared to those without multimorbidity [RR: 2.13 (95% CI 1.62-2.80) p<0.001] and three times greater for people with multimorbidity compared to those without any chronic physical condition [RR: 2.97 (95% CI 2.06-4.27) p<0.001]. There was a 45% greater odds of having a depressive disorder with each additional chronic condition compared to the odds of having a depressive disorder with no chronic physical condition [OR: 1.45 (95% CI 1.28-1.64) p<0.001]. A significant but weak association was found between the number of chronic conditions and depressive symptoms [r = 0.26 (95% CI 0.18-0.33) p <0.001].

LIMITATIONS

Although valid measures of depression were used in these studies, the majority assessed the presence or absence of multimorbidity by self-report measures.

CONCLUSIONS

Depression is two to three times more likely in people with multimorbidity compared to people without multimorbidity or those who have no chronic physical condition. Greater knowledge of this risk supports identification and management of depression.

The Role of Physical Activity on Mood State and Functional Skills of Elderly Women

Introduction:

Ageing is associated with several physical, psychological and behavioral changes. These changes are closely related with global health and functional capacity in the elderly. Mood disturbances are common among the elderly and may significantly increase apathy, resulting in decreased habitual physical activity levels.

Materials and Methods:

The purpose of this cross-sectional study was to evaluate the mood state and functional motor capacities of elderly women engaged in a public physical activity program in Brazil and compare them with physically inactive elderly. Thirty elderly women were included in the study and categorized into two groups: physically active group, composed of participants enrolled on a public physical activity program (n = 16, 69±5 years) and physically inactive group (n = 14, 68±4 years). Total mood disturbance was assessed using the Profile of Mood States, whereas functional motor capacity was evaluated with the Sitting and Rising test. Independent t test and Mann-Whitney U] were used to compare groups.

Results:

The physically active group had lower total mood disturbance (p=0.02), confusion (p<0.01), tension (p<0.01), hostility (p=0.05) and fatigue (p=0.01) compared to the physically inactive group. There were no group differences regarding vigor, depression and sitting and rising performance (p>0.05).

Conclusion:

Lack of difference in functional motor capacity between the physically active and inactive elderly may be explained by the absence of exercise systematization in these programs.

Gender differences in the trajectories and the risk factors of depressive symptoms in later life

BACKGROUND

The present study investigated changes in the trajectories of depressive symptoms in the elderly and attempted to identify risk factors that influence these changes according to gender.

METHODS

All data were obtained from a subsample of subjects who participated in the Korean Longitudinal Study of Ageing between 2006 and 2012; 3,667 individuals (1,566 men and 2,101 women) aged 60 years and older were included in the present study. A group-based trajectory model was employed to determine the appropriate number of groups and to observe changes in depressive symptoms according to research year. Following the trajectory analysis, a multinomial regression analysis was performed to examine depressive symptom-related risk factors that influenced membership in the different trajectory groups.

RESULTS

Significant gender differences were found in the trajectories of depressive symptoms among four groups (normal, mild depressed, worsening, and depressed) in men and five groups (normal, mild depressed, worsening, improving, and depressed) in women. Among the trajectory groups, physical health status such as chronic diseases, self-rated health (SRH), and somatic pain showed statistically significant differences in both genders. In addition, employment in men and social participation in women were associated with the trajectories.

CONCLUSIONS

The present study suggested that maintaining one's physical health status played an important role in preventing depressive symptoms and that employment in men and social participation in women were preventative against the development of depressive symptoms.

Examining Depressive Symptoms and Their Predictors in Malaysia: Stress, Locus of Control, and Occupation

The 2015 National Health and Morbidity Survey estimated that over 29% of the adult population of Malaysia suffers from mental distress, a nearly 3-fold increase from the 10.7% estimated by the NHMS in 1996 pointing to the potential beginnings of a public health crisis. This study aimed to better understand this trend by assessing depressive symptoms and their correlates in a cross-section of Malaysians. Specifically, it assesses stress, perceived locus of control, and various socio-demographic variables as possible predictors of depressive symptoms in the Malaysian context. A total of 728 adults from three Malaysian states (Selangor, Penang, Terengganu) completed Beck’s depression inventory as well as several other measures: 10% of respondents reported experiencing severe levels of depressive symptoms, 11% reported moderate and 15% reported mild depressive symptoms indicating that Malaysians are experiencing high levels of emotional distress. When controlling for the influence of other variables, depressive symptoms were predictably related to higher levels of stress and lower levels of internal locus of control. Ethnic Chinese Malaysians, housewives and those engaged in professional-type occupations reported less depressive symptoms. Business owners reported more depressive symptoms. Further research should look more into Malaysians’ subjective experience of stress and depression as well as explore environmental factors that may be contributing to mental health issues. It is argued that future policies can be designed to better balance individual mental health needs with economic growth.

Sintomas depressivos em idosos: estudo transversal de base populacional

Resumo Foi realizado um estudo transversal de base populacional na cidade de Pelotas, Rio Grande do Sul, em 2014, com o objetivo de medir a prevalência e identificar os fatores associados aos sintomas depressivos em idosos. A amostragem foi realizada por conglomerados em dois estágios. Todos os idosos (≥ 60 anos) residentes nos domicílios selecionados foram convidados a participar. A ocorrência dos sintomas depressivos foi medida utilizando-se a GDS-10 (Geriatric Depression Scale) com o ponto de corte ≥ 5. Foram obtidas informações de 1.451 idosos. A prevalência dos sintomas depressivos foi de 15,2% (IC95% 13,2-17,2). Após análise multivariável, a ocorrência de sintomas depressivos foi maior entre as mulheres, os idosos de pior situação econômica, aqueles que não trabalhavam, os fisicamente inativos, aqueles com pior autoavaliação de saúde e naqueles com incapacidade funcional. Maior atenção deve ser dada à identificação de sintomas depressivos em idosos e seus fatores associados para fundamentar políticas e planejamentos de intervenções para tratamento e manejo desta doença em nível coletivo.

Assessing cardiorespiratory capacity in older adults with major depression and Alzheimer disease

ABSTRACT Objective To assess cardiorespiratory capacity through subjective and objective tests in older adults diagnosed with major depression (MDD), Alzheimer disease (AD) and healthy older adults. Methods Fifty seven subjects (72 ± 7.9 years) were divided into three groups: MDD (n = 20), AD (n = 17) and Healthy (n = 20). The subjects answered Hamilton Scale (HAM-D), Mini-Mental State Examination (MMSE), Veterans Specific Activity Questionnaire (VSAQ) and 2-minute Step test. Results MDD and AD showed lower scores than healthy group for Nomogram VSAQ (p < 0.001) and 2-minute Step (p = 0.009; p = 0.008, respectively). Adjusted for age and educational level, no differences among groups were observed for Step (MDD, p = 0.097; AD, p = 0.102). AD group did not present differences to healthy group for Step, when adjusting for MMSE (p = 0.261). Conclusions Despite the lower cardiorespiratory fitness of elderly patients with DM and DA have been found in both evaluations, the results should be viewed with caution, since the tests showed low correlation and different risk classifications of functional loss. In addition, age, level educational and cognitive performance are variables that can influence the performance objective evaluation.

Factors associated with depression among elderly Koreans: the role of chronic illness, subjective health status, and cognitive impairment

OBJECTIVES

The objective of this cross-sectional study was to investigate the relationship between depression in elderly individuals and chronic illness, subjective health status, and cognitive impairment.

METHOD

This study used the dataset of the Survey of Living Conditions and Welfare Needs of Korean Older Persons, which was conducted by the Korea Institute for Health and Social Affairs in 2011. Participants (n = 10,674) were randomly selected from a pool of individuals aged 65 years and older. Elderly depression was evaluated by the short version of the Geriatric Depression Scale. Multivariate logistic regression was used to investigate factors associated with depression in terms of their sociodemographic and health-related characteristics.

RESULTS

Our results revealed that chronic illness, subjective health status, and cognitive impairment were significant factors associated with depression. In particular, subjective health status showed the highest odds ratio (OR) (OR for bad subjective health status = 4.290, P < 0.001), followed by chronic illness (OR for three or more chronic illnesses = 1.403, P < 0.01) and cognitive impairment (OR = 1.347, P < 0.001) in the final model. Interestingly, the significant association between chronic illness and depression was attenuated (OR for three or more chronic illnesses = 1.403, P = 0.01) or even disappeared (OR for two chronic illnesses = 1.138, P = 0.274; OR for one chronic illnesses = 0.999, P = 0.996) after adjustment for subjective health status in the final model; this may be attributable to the close relationship among the variables studied: chronic illness, subjective health status, and depression.

CONCLUSIONS

Development and implementation of prevention strategies, including management of chronic illness, individual's perception of health status, and cognitive impairment, could possibly reduce the impact of depression.

The prevalence and predictors of severe depression among the elderly in Malaysia

The population of Malaysia is relatively young, due to this there is a dearth in research conducted among the elderly especially relating to depression. The aim of this study is to determine the prevalence and the predictors of severe depression among the elderly in Malaysia. A sample of 2005 older adults randomly selected from the Penang State government's list of elderly receiving aid participated in the study. The Geriatric Depression Scale was used to screen for depression. Socio-demographic, social support, disease, functional and other factors were looked at as possible predictor variables. The prevalence of severe depression was 19.2 %. Indians (aOR = 2.0), being married (aOR = 10.5), widowed & divorced (aOR = 5.2), having poor (aOR = 2.7) or moderate social support (aOR = 2.7), having no one (aOR = 2.9), relatives (aOR = 2.3) or religious figures & others (aOR = 1.9) as compared to a spouse as a source of emotional support, feeling extremely lonely (aOR = 3.4), not socially active (aOR = 2.3), cognitively impaired (aOR 2.5), activities limited due to illness or disability (aOR = 1.6) and poor sleep quality (aOR = 3.6) were significant predictor variables. The prevalence of severe depression was high. It is pertinent that older adults, especially those with risk factors identified in this study be screened for depression at every opportunity.

The Relationship of Built Environment to Health-Related Behaviors and Health Outcomes in Elderly Community Residents in a Middle Income Country

Background

Few studies have examined the impact of the built environment (BE) on health behaviours and health outcomes in middle income countries. This study examines associations between self-assessed characteristics of the home and neighbourhood environment and health-related behaviours and health outcomes in an elderly population in Brazil

Design and methods

In a community sample of 6963 community dwellers 60 years old and older living in the state of Rio Grande do Sul, Brazil, associations between self-reported BE conditions and health behaviours and health outcomes were assessed using a structured questionnaire. Multivariate analysis was conducted to investigate these associations while accounting for other relevant characteristics.

Results

We found significant positive associations between adverse BE conditions and pulmonary, urinary conditions, gastrointestinal, problems, headache and depression. There were mixed associations between adverse BE conditions and musculoskeletal and sensory conditions, inverse associations with metabolic disorders. and no associations with dermatologic problems and cancer. After accounting for health related behaviours, results suggest a modest association between adverse BE conditions and hypertension, with no significant associations with other indicators of cardiovascular conditions (heart problems, stroke, varicose veins).

Conclusions

The findings in this study suggest links between adverse conditions in the BE and health related behaviours in the hypothesized direction. Associations with the health conditions examined here are mixed. We find the strongest evidence for effects of adverse BE conditions for pulmonary and infectious conditions. Significant associations between the adverse BE indicators and health outcomes persist after accounting for health related behaviours, suggesting that BE conditions are linked to health pathways above and beyond the health related behaviours assessed in this study.

Screening for depressive symptoms in older adults in the Family Health Strategy, Porto Alegre, Brazil

OBJECTIVE

To analyze the prevalence of depression in older adults and associated factors.

METHODS

Cross-sectional study using a stratified random sample of 621 individuals aged ≥ 60 from 27 family health teams in Porto Alegre, RS, Southern Brazil, between 2010 and 2012. Community health agents measured depression using the 15-item Geriatric Depression Scale. Scores of ≥ 6 were considered as depression and between 11 and 15 as severe depression. Poisson regression was used to search for independent associations of sociodemographic and self-perceived health with both depression and its severity.

RESULTS

The prevalence of depression was 30.6% and was significantly higher in women (35.9% women versus 20.9% men, p < 0.001). The variables independently associated with depression were: female gender (PR = 1.4, 95%CI 1.1;1.8); low education, especially illiteracy (PR = 1.8, 95%CI 1.2;2 6); regular self-rated health (OR = 2.2, 95%CI 1.6;3.0); and poor/very poor self-rated health (PR = 4.0, 95%CI 2.9;5.5). Except for education, the strength of association of these factors increases significantly in severe depression.

CONCLUSIONS

A high prevalence of depression was observed in the evaluations conducted by community health agents, professionals who are not highly specialized. The findings identified using the 15-item Geriatric Depression Scale in this way are similar to those in the literature, with depression more associated with low education, female gender and worse self-rated health. From a primary health care strategic point of view, the findings become still more relevant, indicating that community health agents could play an important role in identifying depression in older adults.

Effects of Health Status and Health Behaviors on Depression Among Married Female Immigrants in South Korea

PURPOSE

This study examined the effects of health status and health behaviors on depression in married female immigrants in South Korea.

METHODS

Sampling 316 immigrant women from the Philippines, Vietnam, China, and other Asian countries, a cross-sectional research design was used with self-report questionnaires that assessed sociodemographic characteristics, health status, health behaviors, and depression.

RESULTS

There were significant differences in stillbirth experience, induced abortion, morbidity, perceived health status, meal skipping, and physical activity between depressed and nondepressed immigrant women. After adjusting for sociodemographic variables, stillbirth experience, poorer perceived health status, more meal skipping, and less physical activity were associated with greater depressive symptoms.

CONCLUSIONS

Both health status and health behaviors had significant impacts on depression, suggesting that development of nursing interventions and educational programs should be targeted towards improving maternal health, healthy lifestyle, and subjective health perception to promote married female immigrants' psychological well-being.

Prevalência de sintomas depressivos e fatores associados em idosos no norte de Minas Gerais: um estudo de base populacional

Objetivo Avaliar a prevalência e os fatores associados aos sintomas depressivos em idosos não institucionalizados. Métodos Estudo transversal, analítico, de base populacional, cujos dados foram coletados entre maio e julho de 2013, em visitas domiciliares. Foi aplicado um questionário com variáveis sociodemográficas, comorbidades, utilização de serviços de saúde, escala de fragilidade (Edmonton Frail Scale), teste Timed Get Up and Go e a Escala de Depressão Geriátrica (Geriatric Depression Scale – GDS-15). Para análise estatística, as variáveis foram dicotomizadas. Conduziram-se análises bivariadas (teste qui-quadrado de Pearson) adotando-se nível de significância menor que 0,20 para inclusão das variáveis independentes no modelo múltiplo. O modelo final foi gerado por meio de análise de regressão logística múltipla e as variáveis mantidas apresentaram associação com sintomas depressivos em um nível de significância de 0,05 (p < 0,05). Resultados A prevalência de sintomas depressivos foi de 27,5%. As variáveis independentes associadas a sintomas depressivos foram: não ter companheiro (a) (OR = 1,81; IC 95% 1,214-2,713), não saber ler (OR = 1,84; IC 95% 1,19-2,836), percepção negativa sobre a própria saúde (OR = 2,12; IC 95% 1,373-3,256), tabagismo (OR = 2,31; IC 95% 1,208-4,431), alto risco de quedas (OR = 1,78; IC 95% 1,000-3,184) e fragilidade (OR = 2,38; IC 95% 1,510-3,754). Conclusões A alta prevalência de sintomas depressivos identificada entre idosos comunitários alerta para a necessidade de maiores cuidados com a população idosa.

Prevalence and correlates of physical inactivity among older adults in Rio Grande do Sul, Brazil

Background

Current information on the epidemiology of physical inactivity among older adults is lacking, making it difficult to target the inactive and to plan for interventions to ameliorate adverse effects.

Objectives

To present statewide representative findings on the prevalence of physical inactivity among older community residents, its correlates and associated health service use.

Methods

A representative non-institutionalized random sample of 6963 individuals in Rio Grande do Sul, Brazil, aged ≥60 years, was interviewed face-to-face. Information was obtained on demographic characteristics, social resources, health conditions and behaviors, health service use, and physical inactivity. Controlled logistic regression was used to determine the association of physical inactivity with these characteristics.

Results

Overall, 62% reported no regular physical activity. Physical inactivity was significantly more prevalent among women, older persons, those with lower education and income, Afro-Brazilians (73%; White: 61%; “other”: 64%), those no longer married, and was associated with multiple individual health conditions and impaired activities of daily living (ADL). In adjusted analyses, associations remained for sociodemographic characteristics, social participation, impaired self-rated health, ADL, vision, and depression (odds ratios (OR) 1.2–1.7). Physically inactive respondents were less likely to report outpatient visits (OR 0.81), but more likely to be hospitalized (OR 1.41).

Conclusions

Physical inactivity is highly prevalent, particularly among Afro -Brazilians. It is associated with adverse sociodemographic characteristics; lack of social interaction; and poor self-rated health, ADL, vision, and depression; although not with other health conditions. Self-care may be neglected, resulting in hospitalization.

Screening for depression in low-income elderly patients at the primary care level: use of the patient health questionnaire-2

INTRODUCTION

Depression is one of the most common mental disorders and a leading cause of disability worldwide. It constitutes a serious public health problem, particularly among elderly individuals. Most depressed elderly patients are treated by primary care (PC) physicians. The "Patient Health Questionnaire" (PHQ-2) is an instrument used for the detection of depression in PC settings.

OBJECTIVE

Evaluate the performance of the PHQ-2 in a low-income and uneducated elderly PC population.

METHODS

A non-probabilistic population sample of 142 individuals was selected from the healthcare unit's users ≧ 60 years. Criterion validity was assessed by estimating the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the PHQ-2 in comparison with the structured interview using the DSM-IV. The estimates of sensitivity and specificity were obtained from varying cut-offs of the PHQ-2 score. A Receiver Operator Characteristic (ROC) curve was constructed and the area under the curve (AUC) was calculated.

RESULTS

The group was predominantly female (73.9%), with low education level (mean 3 years of schooling). The mean age was 72.5 years old. The prevalence of depression was 26.1%. The best values of sensitivity (0.74), specificity (0.77), PPV (0.50) e NPV (0.90) were obtained with score equal to 1. The AUC was 0.77, indicating a modest performance of the test accuracy.

CONCLUSION

The simplicity of the PHQ-2 is an advantage for its use in PC. The high NPV indicated that 90% of those who tested negative would not need additional tests. However, the low PPV indicated that the PHQ-2 is not sufficient to screen for depression. The application of the instrument could be the first step of the screening, that would include a second step to all those with positive tests formerly.

Proportion and factors associated with depressive symptoms among elderly in an urban slum in Bangalore

Depression among elderly is emerging as an important public health issue in developing countries like India. Published evidence regarding the magnitude and determinants of depression among elderly hailing from urban slum is currently limited. Hence, the current study was conducted to assess magnitude of the problem and identify factors associated with depression among the elderly in an urban slum. A cross-sectional study was done to cover total of 473 elderly persons from an urban slum in Bangalore, India. They were assessed for depression using Center for Epidemiologic Studies Depression scale. The overall prevalence of depression was found to be 37.8 (95% CI = 33.43-42.16). Multivariate analysis revealed that unemployment (self or children) (odds ratio (OR) 2.6; 95% confidence interval (CI) 1.41-4.72), illness of self (OR 2.2; 95% CI 1.45-3.21), female gender (OR 1.9; 95% CI 1.19-2.89), conflicts in family (OR 1.6; 95% CI 1.03-2.43), and marriage of children or grandchildren (OR 1.6; 95% CI 1.02-2.68) as independent risk factors. Depression among elderly is an important health issue of this area. Psychological intervention need to be provided for all elderly persons especially at the time of being diagnosed with any kind of illness. Strategies should be targeted to the females. The stressful life events need to be identified and remedial actions taken. This facility should be made available to them at the primary level of health care. There is a need to include screening of depression in our national health programs.

Estudo longitudinal dos fatores associados à evolução de sintomas depressivos em idosos institucionalizados

Objetivos : Constatando que a depressão é comum em idosos institucionalizados, associando-se à solidão, à ansiedade e à afetividade, pretendemos descrever a evolução da depressão durante dois anos e verificar que fatores se associam a essa evolução. Métodos : Em um estudo de coorte prospectivo em dois momentos (2011 e 2013), avaliamos 83 idosos institucionalizados, com idade no primeiro momento entre os 60 e os 100 anos, sendo 79,5% mulheres, 86,7% sem companheiro(a), e 72,3% com algum grau de escolaridade. Usamos a Escala Geriátrica da Depressão (GDS), a Escala de Solidão (UCLA-L), o Inventário Geriátrico de Ansiedade (GAI) e a Lista de Afetos Positivos e Negativos (PANAS). Resultados: Verificamos que 59,0% mantiveram a depressão e 10,8% desenvolveram depressão. Os idosos com depressão tiveram significativamente piores resultados na UCLA, GAI e PANAS, e os não depressivos tiveram afetos positivos mais altos. Quanto à evolução da depressão, os idosos que mantiveram depressão tiveram inicialmente pontuações elevadas no GDS, GAI, UCLA e na subescala PANAS negativo e pontuações baixas na subescala PANAS positivo. Esses idosos apresentaram associadamente um agravamento dos sentimentos de solidão, dos sintomas ansiosos e do afeto negativo ao longo dos dois anos. Os que desenvolveram depressão tiveram, no primeiro momento, pontuações elevadas na UCLA. Conclusões: Os sintomas de depressão com ou sem solidão no momento inicial, o agravamento da solidão, a ansiedade, o afeto negativo e o baixo afeto positivo poderão ser fatores de risco para a manutenção da depressão. A solidão poderá ainda ser um fator de risco para o desenvolvimento de depressão.

Neuroscience of exercise: from neurobiology mechanisms to mental health

The neuroscience of exercise is a growing research area that is dedicated to furthering our understanding of the effects that exercise has on mental health and athletic performance. The present study examined three specific topics: (1) the relationship between exercise and mental disorders (e.g. major depressive disorder, dementia and Parkinson's disease), (2) the effects of exercise on the mood and mental health of athletes, and (3) the possible neurobiological mechanisms that mediate the effects of exercise. Positive responses to regular physical exercise, such as enhanced functional capacity, increased autonomy and improved self-esteem, are frequently described in the recent literature, and these responses are all good reasons for recommending regular exercise. In addition, physical exercise may improve both mood and adherence to an exercise program in healthy individuals and might modulate both the performance and mental health of athletes. Exercise is associated with the increased synthesis and release of both neurotransmitters and neurotrophic factors, and these increases may be associated with neurogenesis, angiogenesis and neuroplasticity. This review is a call-to-action that urges researchers to consider the importance of understanding the neuroscience of physical exercise and its contributions to sports science.

Bidirectional association between mental health and physical activity in older adults: Whitehall II prospective cohort study

OBJECTIVE

To investigate longitudinal and bidirectional associations between mental health and physical activity from midlife into old age.

METHODS

Analysis was based on data from 6909 participants (aged 45 to 69 in 1997/99) from the Whitehall II cohort in the UK. Latent growth curve analysis examined possible bidirectional associations between the SF-36 Mental Component Summary and weekly physical activity measured at three time-points over ten years.

RESULTS

Mental health and physical activity were associated at baseline (β=0.17, 95% CI 0.13, 0.21) and associations persisted into old age. In the latent growth curve model, both mental health and physical activity increased and their rates of change 'moved together' over time (β=0.24, 95% CI 0.11, 0.37). Relatively high baseline levels of either variable were associated with slightly slower increases in the other outcome (β=-0.02, 95% CI -0.03, -0.01; β=-0.07, 95% CI -0.11, -0.13), which are thought to reflect regression to the mean. However, those who started high on either variable remained the most advantaged at end of follow-up.

CONCLUSIONS

From midlife to old age, greater physical activity is associated with better mental health and vice versa. These findings suggest persistent longitudinal and bidirectional associations between physical activity and mental health.

Impact of physical exercise on quality of life of older adults with depression or Alzheimer's disease: a systematic review

INTRODUCTION: Physical exercise has been associated with improvement of quality of live (QoL), but its effect among the elderly with depression and Alzheimer's disease (AD) is still unclear. This systematic review evaluated randomized and controlled studies about the effect of physical exercise on QoL of older individuals with a clinical diagnosis of depression and AD.METHODS:We searched PubMed, ISI, SciELO and Scopus from December 2011 to June 2013 using the following keywords: physical exercise, quality of life, elderly, depression, Alzheimer's disease. Only six studies met inclusion criteria: two examined patients with AD and four, patients with depression.RESULTS: The studies used different methods to prescribe exercise and evaluate QoL, but all had high quality methods. Findings of most studies with individuals with depression suggested that exercise training improved QoL, but studies with patients with AD had divergent results.CONCLUSIONS: Although different methods were used, results suggested that physical exercise is an effective non-pharmacological intervention to improve the QoL of elderly individuals with depression and AD. Future studies should investigate the effect of other factors, such as the use of specific scales for the elderly, controlled exercise prescriptions and type of control groups.

Gender differences in the relationship between physical functioning and depressive symptoms in low-income older adults living alone

This study examined gender differences in the relationship between physical functioning and depressive symptoms in low-income older adults living alone in Korea, and the variables influencing these symptoms. Data from a total of 317 older adults in the 2011 Korean National Survey were used. Upper limb mobility, lower limb mobility, activities of daily living, instrumental activities of daily living, and depressive symptoms were measured. Data were analyzed using multiple regression analysis. Low-income older men and women living alone experienced depressive symptoms. Regression analysis showed that lower limb mobility and age together explained 35.4% of the variance in depressive symptoms in men. Subjective health status explained 16.7% of the same in women. These findings suggest that low-income older adults living alone should be carefully monitored by public healthcare managers to improve their physical and mental health, considering gender-specific elements.

The biological clock keeps ticking, but exercise may turn it back

Aging is an inevitable process that is associated to loss of functional capacities in several body systems, like the cardiovascular, the skeletal muscle mass, the osteoarticular and the neuro-immune-endocrine systems. Changes appear due to interactions between genetic factors and way of life, such as diet and sedentary life style. This review shows evidence from the past twenty years concerning the importance of physical exercise to reduce the deleterious effects of aging, regarding the improvement in functional performance, the prevention of diseases and increased longevity. Moreover, physical exercise improves the cognitive function and the mood. Aerobic and strength training collaborate with the prevention and treatment of mental diseases, which are mostly prevalent in older adults, like major depression, dementia and Parkinson's disease. Several mechanisms of neurobiological action are proposed to explain how exercise can actually reduce the effects of aging.

The association of health and income in the elderly: experience from a southern state of Brazil

OBJECTIVES

In high income, developed countries, health status tends to improve as income increases, but primarily through the 50(th)-66(th) percentile of income. It is unclear whether the same limitation holds in middle income countries, and for both general assessments of health and specific conditions.

METHODS

Data were obtained from Brazil, a middle income country. In-person interviews with a representative sample of community residents age ≥ 60 (N=6963), in the southern state of Rio Grande do Sul, obtained information on demographic characteristics including household income and number of persons supported, general health status (self-rated health, functional status), depression, and seven physician-diagnosed, self-reported health conditions. Analyses used household income (adjusted for number supported and economies of scale) together with higher order income terms, and controlled for demographics and comorbidities, to ascertain nonlinearity between income and general and specific health measures.

RESULTS

In fully controlled analyses income was associated with general measures of health (linearly with self-rated health, nonlinearly with functional status). For specific health measures there was a consistent linear association with depression, pulmonary disorders, renal disorders, and sensory impairment. For musculoskeletal, cardiovascular (negative association), and gastrointestinal disorders this association no longer held when comorbidities were controlled. There was no association with diabetes.

CONCLUSION

Contrary to findings in high income countries, the association of household-size-adjusted income with health was generally linear, sometimes negative, and sometimes absent when comorbidities were controlled.

Relationship between physical activity and depression and anxiety symptoms: a population study

BACKGROUND

There are few studies evaluating the association between practice of physical activity and mood in a population sample. This study evaluated the frequency of symptoms of depression and anxiety in the population of the city of Sao Paulo and their association with the report of practice of regular physical activity.

METHODS

This survey was conducted with the adult population of Sao Paulo between July and December of 2007. The sample was composed of 1042 volunteers (both genders) with a mean age of 41.9±14.4 years. The volunteers were evaluated using the Beck Depression Inventory, the Beck Anxiety Inventory, and two simple questions designed to evaluate and classify physical activity. Socioeconomic status was also determined according to Brazil's Economic Classification Criterion.

RESULTS

People who do not engage in physical activity are two times more likely to exhibit symptoms of depression (PR: 2.1) and anxiety (PR: 2.5) compared with those who regularly practice physical activity and a higher prevalence of symptoms for anxiety (9.8%) and depression (10.9%) was observed among those claiming to not practice regular physical activity and 63.2% related did not practice any physical activity regularly.

CONCLUSION

Altogether, these results suggest that people who do not practice physical activity have a higher chance of exhibiting symptoms of depression and anxiety when compared to those who perform physical activity regularly. In this sense, regular physical activity must be encouraged, and this incentive should be routine in both current and future public health policies. Although the methodology in the present study does not allow assigning a relation of cause and effect, we observed associations between symptoms of depression, anxiety and physical activity.

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).

Clinical and sociodemographic factors in a sample of older subjects experiencing depressive symptoms

OBJECTIVES

This study aims to determine the frequency of clinically significant depressive symptoms (CSDS) in a community sample of older Brazilians and to examine their relationship with sociodemographic factors, cognitive and functional impairment (CFI), and medical illness.

METHODS

A total of 1145 subjects aged 60 years or older living in the City of Ribeirao Preto, State of Sao Paulo, Brazil, were interviewed. The following instruments were used: a 10-item scale for screening of depressive symptoms in older people, the mini mental state examination, the Fuld object memory evaluation, the informant questionnaire on cognitive decline in the elderly, the Bayer activities of daily living scale, and a sociodemographic and clinical questionnaire.

RESULTS

The frequency of CSDS was 15.7%. Logistic regression analysis indicated that being previously depressed, having CFI, having lower level of education, using psychotropics, and not engaging in physical exercise were related to CSDS. On the other hand, being a woman, older, medically ill, employed, or married was not associated with CSDS.

CONCLUSIONS

Consistent with previous reports, lower education, lack of physical activity, and CFI were significantly associated with higher frequencies of CSDS. Further investigations are necessary to clarify the occurrence of depression and possible modifiable factors in developing countries such as Brazil.

Comparisons of the prevalence of and risk factors for elderly depression between urban and rural populations in Japan

BACKGROUND

The aim of the present study was to investigate the differences in the prevalence of and risk factors for elderly depression between urban and rural areas in Japan and to further understanding of the features of elderly depression.

METHODS

A multistage, random sampling procedure and mailing method were used in urban and rural areas in Kumamoto Prefecture. A total of 2,152 participants aged 65 years and older were evaluated for depression using the Geriatric Depression Scale (GDS). Factors associated with depression were also examined. In order to assess the relationship between risk factors and subjective happiness, the Philadelphia Geriatric Center Morale Scale (PGC-MS) was used.

RESULTS

Depressive symptoms were associated with living alone, being unemployed, chronic illness, sleep disturbance, suicidal ideation, financial strain, and poor social support; the risk factors for elderly depression were almost the same in the two areas. Although three factors (financial strain, work status, and PGC-MS) were significantly associated with depression in both areas on logistic regression analysis, sleep disturbance was significant only for the urban area, and poor social support was significant only for the rural area.

CONCLUSIONS

Although factors related to depression did not differ markedly between urban and rural elderly people, some risk factors differed between the two areas. Effective intervention programs for elderly depression should pay more attention to regional differences.

Living arrangements and risk for late life depression: a meta-analysis of published literature

OBJECTIVE

The goal of this study was to determine the relationship between living arrangements and risk for depression among older people.

METHOD

MEDLINE, EMBASE, The Cochrane Library database was used to identify potential studies. The studies were divided into cross-sectional and longitudinal subsets. Qualitative meta-analysis of the cross-sectional studies and longitudinal studies was performed, respectively. For prevalence and incidence rates of depression, odds ratio (OR) and relative risk (RR) were calculated, respectively.

RESULTS

The qualitative meta-analysis showed that older people living alone had a higher risk of depression than those not living alone (OR: 1.44; 95% confidence interval [95% CI]: 1.04-1.99); Relative risk (RR: 1.27, 95% CI: 0.89-1.80) and those living with families (OR: 2.59, 95% CI: 1.60-4.20). Older people living in a nursing home (OR: 2.90, 95% CI: 0.94-8.94; RR: 1.94, 95% CI: 1.18-3.20) or institutionalized setting (OR: 1.86, 95% CI: 1.37-2.52; RR: 2.03, 95% CI: 1.12-3.70) had a higher risk of depression than those living in home.

CONCLUSIONS

Despite the methodological limitations of this meta-analysis, living arrangements appear related to the risk for depression in the older population. Older persons living alone, in a nursing home, or in an institutionalized setting have higher risk for depression.

Association between life events and change in depressive symptoms in Hong Kong Chinese elderly

BACKGROUND

Life event was regarded as an important risk factor for depression. Only a few prospective studies had examined the impact of life events individually and in combination. This study examined the relationship between life events and change in depressive symptoms.

METHODS

Depressive symptoms were assessed longitudinally using Geriatric Depression Scale (GDS) in 2630 community-dwelling Chinese elderly aged 65 or above. A cutoff score of 8 or higher indicated clinically relevant depressive symptoms. Subjects identified as demented were excluded. Eight life events experienced in the past year were assessed at 2year follow up. Logistic regression analyses were performed with adjustments for baseline GDS score and potential confounders such as sociodemographic, developmental and social factors, alcohol consumption, medical history and physical health status.

RESULTS

In men, experience of two events (OR=2.493) and three or more events (OR=3.199) was independently associated with increased risk of having depression. In women, the risk increased only in experiencing three or more events (OR=5.558). Moreover, life event affected depressive symptoms differently for men and women. Loss of pet and serious financial trouble were associated with an increase in depressive symptoms among men, but serious illness or accident of partner, and loss of a hobby were significant among women. Experience in either good or bad important events increased risk of depression in both sexes.

LIMITATIONS

The main limitation was all subjects were ambulatory volunteers.

CONCLUSIONS

The occurrence of single life event had contributed to the onset of depression and multiple events had a cumulative effect.

Association among physical, psychiatric and socioeconomic conditions and WHOQOL-Bref scores

The aim of this study is to investigate the impact of psychiatric morbidity, depression, cognitive deficit, number of self-reported illnesses and socio-demographic variables on the WHOQOL-Bref domain scores. WHOQOL-Bref domain scores are substantially affected by psychiatric morbidity and income. Depression, the number of self-reported illnesses and the female gender also explain the variability of other domains to a lesser extent.

Factors associated with depressive symptoms among older adults living alone: an analysis of sex difference

OBJECTIVES

The aim of this study was to explore the prevalence of depressive symptoms and the risk factors that correlated with depressive symptoms among elders living alone.

METHODS

A cross-sectional design was implemented. The sample consisted of 117 women and 75 men aged 65 and older who living alone in Tainan, Taiwan. The Chinese version of Center for Epidemiological Studies Depressive Symptoms Scale was adopted to assess depressive symptoms. Logistic regression analyses were employed to determine the risk factors of depressive symptoms in the elderly women and men living alone.

RESULTS

Results of this study showed that the elderly women had a 1.6-fold greater prevalence of depressive symptoms than did men. Women who were aged 85 and above, and less social support, had a significantly higher occurrence rate of depressive symptoms. The risk factors for depressive symptoms in elderly men living alone included educational level, religious beliefs, self-rated health status, number of chronic illnesses, and social support.

CONCLUSIONS

Healthcare providers should reflect the sex difference on risk factors of depressive symptoms when planning mental health services for the elderly population.

Increased health burden associated with comorbid depression in older Brazilians with diabetes

BACKGROUND

The health burden associated with comorbid depression and diabetes in older community residents in middle income countries is unclear.

METHODS

Data came from a statewide representative sample (N = 6963, age ≥ 60) in Brazil. Controlled polytomous logistic regression was used to determine whether four mutually exclusive groups (all possible combinations of the presence or absence of depression and diabetes) differed in sociodemographic characteristics, social resources, health behaviors, and selected health conditions.

RESULTS

While 2.37% were expected to have comorbid depression/diabetes given sample base rates (depression: 20.92% [1457/6963]; diabetes: 11.35% [790/6959]), comorbidity was present in 3.62% (52.5% beyond expectation; P<0.0001; OR = 1.58, 95% Confidence Interval 1.29-1.95). Depression without diabetes was reported by 17.3%, and diabetes without depression by 7.7%. In controlled analyses, the depression group had poorer socioeconomic status and health behaviors, and a greater likelihood of vascular, respiratory, and musculoskeletal problems than the diabetes group. Vascular, respiratory, and urinary problems were exacerbated in comorbid depression/diabetes; the comorbid group was also more likely to be female and younger.

LIMITATIONS

Cross-sectional design.

CONCLUSIONS

To our knowledge, this is the first study that explicitly reports on all four possible depression/diabetes combinations in an older representative community-resident sample, using controlled analyses to identify unique associations with sociodemographic characteristics and other health conditions. The burden of comorbid depression/diabetes in Brazil, a middle income country, appears to be comparable to that found in higher income countries. So, similarly, depression without diabetes had a greater odds of adverse sociodemographic and health conditions than diabetes without depression; comorbid depression/diabetes was more likely in women and young elderly, and the odds of vascular, respiratory, and urinary conditions was increased significantly. Attention to comorbid depression/diabetes as a unique entity is needed.

Marital Status and Risk for Late Life Depression: A Meta-Analysis of the Published Literature

This study assessed the relationship between marital status and the risk for depression in people ≥ 55 years old. Using the Medline™, EMBASE™ and Cochrane Library databases, clinical studies that published data on the association between marital status and risk of depression among individuals aged ≥ 55 years were identified. A quantitative meta-analysis of 24 cross-sectional and eight longitudinal studies was performed. Compared with married elderly people, unmarried elderly people had a higher risk for depression (odds ratio [OR], 1.55; relative risk [RR], 1.36). Compared with married elderly people, the widowed elderly people (OR 1.49; RR 1.71), divorced people (RR 2.14) and never-married people (OR 1.32) had a higher risk for depression. Among elderly unmarried people, widowed people had a higher risk for depression than those who never married (OR 1.51). In conclusion, being unmarried was an important risk factor for depression in elderly people.

The Pietà study: epidemiological investigation on successful brain aging in Caeté (MG), Brazil. Methods and baseline cohort characteristics

OBJECTIVES: To present the methods and baseline characteristics of the Pietà study, a population-based survey investigating successful brain aging in the oldest-old. METHOD: The study was conducted in Caeté (MG), Brazil. In 2007, 1,251 individuals aged 75+ years were living in the city and were invited to participate. Participants responded to a general health questionnaire and were submitted to clinical, neurological, cognitive, psychiatric and functional evaluations. A subgroup was submitted to neuropsychological testing, blood tests and magnetic resonance of the skull. Individuals were classified as having cognitive impairment-no dementia, dementia, parkinsonism, psychiatric disorders or successful brain aging. RESULTS: We evaluated 639 individuals (51.1% of the target population; 64% women), aged 81.4±5.2 years and with 2.7±2.6 years of schooling. Almost 30% of the elderly were illiterates and 82.1% belonged to middle/middle-low socioeconomic levels. Almost 50% were widows, but only 14.3% were living alone. CONCLUSION: The Pietà cohort is representative of the oldest-old Brazilian population. We believe the results of the study may contribute to increase our knowledge about healthy and pathological brain aging in the oldest-old.

Psychiatry: life events and social support in late life depression

OBJECTIVES

To examine the association of life events and social support in the broadly defined category of depression in late life.

INTRODUCTION

Negative life events and lack of social support are associated with depression in the elderly. Currently, there are limited studies examining the association between life events, social support and late-life depression in Brazil.

METHODS

We estimated the frequency of late-life depression within a household community sample of 367 subjects aged 60 years or greater with associated factors. ''Old age symptomatic depression'' was defined using the Composite International Diagnostic Interview 1.1 tool. This diagnostic category included only late-life symptoms and consisted of the diagnoses of depression and dysthymia as well as a subsyndromal definition of depression, termed ''late subthreshold depression''. Social support and life events were assessed using the Comprehensive Assessment and Referral Evaluation (SHORT-CARE) inventory.

RESULTS

''Old age symptomatic depression'' occurred in 18.8% of the patients in the tested sample. In univariate analyses, this condition was associated with female gender, lifetime anxiety disorder and living alone. In multivariate models, ''old age symptomatic depression'' was associated with a perceived lack of social support in men and life events in women.

DISCUSSION

Social support and life events were determined to be associated with late-life depression, but it is important to keep in mind the differences between genders. Also, further exploration of the role of lifetime anxiety disorder in late-life depression may be of future importance.

CONCLUSIONS

We believe that this study helps to provide insight into the role of psychosocial factors in late-life depression.

Point prevalence of major depression in Estonia. Results from the 2006 Estonian Health Survey

AIM

The study focuses on the point prevalence of major depressive episode in the Estonian population in 2006 and assesses the relationship of sociodemographic factors, health status indicators, alcohol use, and previous depressive episodes to major depression.

METHODS

The present major depressive episode was assessed within the nationally representative, cross-sectional 2006 Estonian Health Survey (EHIS 2006), in which non-institutionalized individuals aged 18-84 years (n=6105) were interviewed using the Mini-International Neuropsychiatric Interview (MINI).

RESULTS

The point prevalence of major depressive episode in the Estonian population was 5.6%. Depression was higher among females, in the non-Estonian ethnic group, among people older than 40 years, and in the lower-income group.

CONCLUSIONS

The point prevalence of major depressive episodes was comparable with the results of other population surveys, being a little higher than the average. Age, income, ethnicity, health status, self-rated health, and previous depressive episode were independent associates of depression.
