Prevalence and risk factors of depression in the elderly nursing home residents in Singapore

Prevalence and risk factors of depression among elderly people in nursing homes from 2012 to 2022: a systematic review and meta-analysis

OBJECTIVES

To determine a pooled prevalence of depression and its influencing factors among nursing home residents.

METHOD

PsycINFO, PubMed, Embase, and Web of Science were searched for studies investigating the prevalence and risk factors of late-life depression among nursing home residents between January 2012 and November 2022. Two reviewers independently completed the literature screening, data extraction and quality assessment. A random-effects model was utilized to pool the prevalence of depression and summarize the influencing factors.

RESULTS

This meta-analysis included 48 studies involving 28,501 participants. The pooled prevalence of depressive mood and major depressive disorder was 53% and 27%, respectively. The rate of depressive mood is higher in lower-middle-income countries (60.0%), compared with high- (53.0%) and upper-middle-income countries (44.0%). The rate of depressive mood (35.0%) is higher among females than male (19.0%). Depression was influenced by factors, including male (OR = 0.28), insufficient income (OR = 3.53), comorbidities (OR = 2.66), pain (OR = 2.67; r = 0.31), functional disability (r = 0.33), loneliness (r = 0.43), number of chronic health problems (r = 0.18), social support (r = -0.28), activities of daily living (r = -0.43), subjective health (r = -0.28), autonomy (r = -0.41), environment (r = -0.50) and physical (r = -0.57) and psychological health (r = -0.65).

CONCLUSION

The prevalence of depressive mood is high among nursing home residents, especially in lower-middle-income countries. It is influenced by factors including gender, income, social support, daily activities, environment, physical and psychological health and autonomy. Understanding those factors can provide evidence-based recommendations for improved awareness, prevention and better management of late-life depression.

Latent profile analysis of depression among empty nesters in China

OBJECTIVES

The study aimed to explore the depression profile of empty nesters and to identify heterogeneous subgroups in the elderly population. It explored the influencing factors of depression in elderly people with different depression profiles, with a view to provide a reference basis for improving the depression situation of empty-nesting elderly people.

METHODS

This study used the Chinese Longitudinal Healthy Lifespan Survey (CLHLS) survey data, with empty nesters over 60 as the research subjects. Latent profile analysis (LPA) was used to fit potential classes of depression in empty nesters; chi-square tests, Kruskal-Wallis, and multinomial logistic regression were used to explore the factors influencing different depression profiles in older adults.

RESULTS

A total of 4481 subjects were included in this study and were classified as low-level (11.6 %), moderate-level (51.6 %), and high-level (36.8 %). Compared to the low-level, the influencing factors for the high-level were IADL, anxiety, self-rated health, exercise, and education; and the influencing factors for the medium level group were anxiety, self-rated health, drink, and education. Factors influencing high-level relative to the mid-level group were IADL, anxiety, residence, self-rated health, exercise, and limited in activities.

LIMITATIONS

The CESD-10, as a screening tool, could not completely determine the presence of depression in high levels of empty nesters.

CONCLUSIONS

Psychological problems arising from depression among empty nesters seriously affected their overall health, and targeted intervention strategies should be developed for different categories of older adults to improve depression and enhance health-related quality of life.

Bidirectional association between major depressive disorder and dementia: Two population-based cohort studies in Taiwan

BACKGROUND

Major depressive disorder (MDD) and dementia are both major contributors to the global burden of disease. Despite existing literature on the association between MDD and dementia, there is a lack of a nationwide longitudinal cohort study that considers the competing risk of death. Therefore, this study assessed the bidirectional associations between MDD and dementia over an 11-year period in population-based settings, accounting for death as a competing risk.

METHODS

We conducted two population-based retrospective cohort studies in Taiwan. We identified 80,742 patients diagnosed with MDD in 2009-2010 and matched them with patients without MDD by sex, age, and year of diagnosis to assess the relative risk of dementia. We also identified 80,108 patients diagnosed with dementia in 2009-2010 and matched them with patients without dementia by sex, age, and year of diagnosis to assess the relative risk of MDD. All patients were followed until they received a diagnosis of new onset MDD or new onset dementia, their death, or the end of 2019. Cause-specific hazards models were used to estimate adjusted hazard ratios (aHRs).

RESULTS

The incidence density (ID) of dementia was higher in patients with MDD than in patients without MDD (7.63 vs. 2.99 per 1000 person-years), with an aHR of 2.71 (95% confidence interval [CI]: 2.55-2.88). The ID of MDD was higher in patients with dementia than in patients without dementia (12.77 vs. 4.69 per 1000 person-years), with an aHR of 2.47 (95% CI: 2.35-2.59).

CONCLUSIONS

This population-based study found a bidirectional association between MDD and dementia. Our findings suggest the need to identify dementia in patients with MDD and vice versa.

Informal antidepressant strategies for nursing home residents: two group concept mapping studies

OBJECTIVES

To identify and structure potential informal antidepressant strategies that can be used in daily practice for nursing home residents alongside formal treatments.

METHODS

In a first Group Concept Mapping study, residents, relatives, and professional caregivers (N = 124) brainstormed on strategies residents could use to prevent or alleviate depression. In a second study, the same participants (N = 110) reported strategies for use by others. Furthermore, participants rated the expected effectiveness and feasibility of the suggested strategies. Simultaneously, all strategies were sorted by experts and clustered using multidimensional scaling and hierarchical cluster analysis.

RESULTS

Six clusters emerged for strategies by residents themselves and five clusters for strategies by others. For residents' strategies, the clusters Being socially connected and Participating in activities were perceived as most effective, as was the cluster Offering personal attention for strategies by others. Participants perceived Creating a healthy living environment as the most feasible cluster executed by residents. Within strategies by others, the clusters Offering personal attention, Using positive treatment/approach, and Using or adapting the physical environment were perceived as the most feasible.

CONCLUSION

The results indicated the importance of social connectedness, a personalized and positive approach by significant others, and tailored activity programs. The results also suggest that adaptations to the physical environment within nursing homes may be an easy applicable strategy to prevent or alleviate depression in residents. Although more research is needed, these findings may guide daily practice and the development of interventions that include informal strategies.

Activities of Daily Living and Depression in Chinese Elderly of Nursing Homes: A Mediation Analysis

Purpose

This study aimed to explore the role of sleep quality as a mediator in the activities of daily living (ADLs) and depression.

Patients and Methods

Participants (N=645; age≥60) were included in six nursing homes in Weifang, Shandong Province, using convenience sampling. Participants completed questionnaires to assess sleep quality, ADLs, and depression. Depression condition was assessed by the Patient Health Questionnaire (PHQ-9), ADLs was assessed by the Barthel Index (BI), and sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI). Mediation analysis was carried out by SPSS PROCESS.

Results

ADLs (r=0.449, P<0.01) and sleep quality (r=0.450, P<0.01) were found to be positively associated with depression among the elderly. Sleep quality plays a significant mediating role in the influence of ADLs on depression in the elderly in nursing homes (Bootstrap 95% CI [0.076, 0.139]), The pathway from ADLs to sleep quality to depression yielded a medium effect size of 20.23%.

Conclusion

ADLs help to explain how sleep quality partly mediates depression among the elderly in nursing homes. It is therefore recommended that timely detection and efficient interventions should focus on promoting physical function and improving sleep quality among the elderly in nursing homes.

Effects of exercise on depressive symptoms among nursing home residents: a meta-analysis

OBJECTIVE

We examined the effects of exercise on depression in older adults living in nursing homes and explored the moderator effects of participants, methods, and intervention characteristics.

METHODS

We searched 8 databases from inception to January 2020 without date restrictions. We retrieved primary studies measuring exercise with 60-year-olds with depression that were written in English. Two researchers independently coded each primary study and compared codes for discrepancies. They consulted a third researcher to come to consensus. We used random-effects model to compute effect sizes using Hedges' g, a forest plot, and Q and I² statistics as measures of heterogeneity. We also examined moderator analyses.

RESULTS

Twenty-one studies included 2,594 participants (81.8 ± 4.8 years old). Overall, exercise showed a small improvement in depression compared to controls (ES=.25; 95%CI 0.11, 0.38; p=.000). Interestingly, interventionists by physiotherapists had a smaller effect on depressive symptoms (.04) than other health interventionists (.37). As people aged, exercise was less effective in reducing depression (slope=-.03, Q_model=5.03, p=.025). Researchers who included a higher percentage of women in exercise showed less improvement of depression (slope=-.01, Q_model=8.60, p=.003). Also, when researchers used depression scales with higher reliability values, they measured higher levels of depression (slope = 5.48, Q_model=5.60, p=.018). No other quality indicators moderated the effects of exercise on depression.

CONCLUSION

Exercise significantly improved depressive symptoms among older adults in nursing homes. Exercise might be used as adjunct/alternative complementary treatment for improving depressive symptoms in older adults in nursing homes.

Effects of Group Music Intervention on Depression for Elderly People in Nursing Homes

Depression is the most common mental problem among the elderly, especially in long-term care facilities. The purpose of the present study was to examine the effects of group music intervention on depression for elderly people in nursing homes. Methods: A randomized control trial consisting of sixty-three elderly participants randomly and blindly assigned to a music group or control group was utilized. The music group received 20 sessions of group music intervention (two 30-min sessions per week for 10 weeks), and the control group received usual care with no music intervention. The Geriatric Depression Scale—Short Form (GDS-SF) and salivary cortisol at baseline, 5 weeks, and 10 weeks were collected for analysis. Results of the GEEs (generalized estimating equations) analysis indicated that after 20 sessions for 10 weeks of group music intervention, the groups showed a statistically significant difference in depression at 5 weeks and 10 weeks. There was no significant difference in the salivary cortisol concentration between the two groups. The results show that the group music intervention may effectively reduce the depression scores for elderly people in nursing homes. Conclusion: The group music intervention has positive effects on depression.

Prevalence of depression and its related factors among older adults in Indonesian nursing homes

Background

Depression is one of the most severe mental disorders experienced by older adults worldwide. The prevalence of depression among older adults in nursing homes is three-time higher than in the community. Therefore, knowing the incident rates of depression and its related factors would help provide appropriate intervention and prevention programs in the future.

Objectives

The study aimed to determine the prevalence of depression and compare the difference in depression status according to the sociodemographic characteristic of the older adults in the Indonesian nursing homes.

Methods

A descriptive cross-sectional study design was used in this study, which involved 116 participants selected using convenience sampling from five different general nursing homes in Bandung City, Indonesia. The Short Form (SF) of the Geriatric Depression Scale (GDS) was used to evaluate depression among older adults in nursing homes. The t-test and one-way ANOVA were used for data analysis.

Results

Of the total participants, 56.9% had depression, which 7.8% with mild depression, 37.1% with moderate depression, and 12% with severe depression. In addition, there were significant differences in depression according to age, gender, marital status, educational background, ethnicity, disease history, duration of stay, and the visitor frequency among the older adults in nursing homes (p <.001).

Conclusion

A high rate of depression among older adults in Indonesian nursing homes was identified. Therefore, attention to caring for more specific needs, such as the psychosocial needs of older adults in nursing homes, is urgent.

Investigating the relationship between satisfaction of basic psychological needs, general health, and some background variables in the Iranian older adults: a cross-sectional study

BACKGROUND

Promoting the health and mental health (MH) of the older adults making up a large part of the world's population in the coming years can provide the necessary conditions for their health and well-being of them. This study aimed to investigate the relationship between the satisfaction of basic psychological needs (BPNs), general health (GH), and some variables in Iranian older adults.

METHODS

The present descriptive-correlational study was conducted on 780 older adults from Sarpol-e Zahab (Kermanshah) in 2019 including the study by multi-stage cluster random sampling. The data collection tool was BPNs satisfaction and GH questionnaire and a researcher-made questionnaire of individual and background information. Was used for data analysis using the SPSS version 16 program and descriptive statistics and tests Pearson correlation coefficient, chi-square test, independent-sample T-test, and multivariate linear regression.

RESULTS

In the present study, participating a total of 780 older adult men aged 73.0 ± 29.32 years. There was a significant relationship between the satisfaction of BPNs and GH (p <  0.001). Also, 41% of the older adults were in poor GH and 30% were high in BPNs. Multiple logistic regression showed that the BPNs, age, income satisfaction, weather, and war zone were strong predictors of GH. the adjusted R2 value of 0.55 shows that the model described 55% of changes in the GH score.

CONCLUSION

According to the findings of the study on the relationship between the satisfaction of BPNs and GH, providing insurance, social and economic support by developing health policies, creating supportive health environments, strengthening community action, and developing individual skills in the older adults can help improve their MH and that of the community.

Exploring changes to resident thriving and associated factors in Swedish nursing homes: A repeated cross-sectional study

OBJECTIVE

This study aimed to explore changes to resident thriving in Swedish nursing homes over a 5-year period and describe changes in associated factors.

METHODS

Cross-sectional data were collected from a randomised sample of Swedish nursing homes in 2013/2014 (baseline) and 2018/2019 (follow-up). Descriptive statistics, independent samples t-tests, and chi squared tests were used to statistically evaluate differences between the samples. Simple and multiple linear regression analyses were used to explore associations between thriving and the study variables.

RESULTS

Resident characteristics were relatively consistent between the full baseline (N = 4831) and follow-up (N = 3894) samples. Within a sub-sample of nursing homes that participated in both data collections mean thriving scores were found to have increased from 152.9 to 155.2 (p ≤ 0.003; d =0.09) and overall neuropsychiatric index scores had decreased from 16.0 to 14.3 (p ≤ 0.004; d =0.09), as had the prevalence of several neuropsychiatric symptoms. Thriving was found to have a positive association with the neuropsychiatric symptom of elation/euphoria, and negative associations with the symptoms of aggression/agitation, depression/dysphoria, apathy, and irritability.

CONCLUSIONS

The results show an increase in overall thriving scores and a decrease in overall neuropsychiatric scores between baseline and follow-up. This study confirmed associations between thriving and certain neuropsychiatric symptoms and established comparative knowledge regarding changes in resident thriving, characteristics, and symptom prevalence. These findings could inform future care and organisational policies to support thriving in nursing homes, particularly among residents at risk of lower thriving due to cognitive impairment or neuropsychiatric symptoms.

Joint Waterpipe and Cigarette Smoking as Key Correlate of History of Depression in Iranian Population: A Cross-Sectional Study

Research on the association between waterpipe smoking and depression is limited. This study aimed to explore the prevalence and adjusted associated correlates of depression among Iranian adult. We analyzed data from 974 participants of a population-based cross-sectional study enrolling 18-50-year-old residents of Tehran, Iran in 2015. Data on lifetime self-reported history of depression, smoking behaviors, socioeconomic status, self-rated health, physical activity, stressful life events as well as a number of relevant confounders was obtained. Logistic regression models were employed for estimating adjusted odds ratios (ORs) and their 95% confidence intervals (CI). The mean (SD) age of the study sample was 32.55 (8.58) years. Of 974 recruited adults, 52.36% were female. The lifetime prevalence of depression in the general population was 17.0%. In general, 21.77% and 24.79% of participant reported lifetime history of cigarette and waterpipe smoking, respectively. While only cigarette smoking (OR = 1.94, 95% CI: (1.04-3.61) and only waterpipe smoking (OR = 1.65, 95% CI: (.95-2.86) were significantly associated with depression, joint cigarette and waterpipe smoking (OR= 3.76, 95% CI: (1.99-6.08) was the strongest correlate of depression followed by female gender (OR = 3.28, 95% CI: (2.08-5.15) and poor self-rated health (OR = 2.47, 95% CI: (1.73-3.53). The prevalence of self-reported depression in general population of Tehran is considerably higher than its global mean. We reported joint cigarette and waterpipe smoking as a significant correlate with depression in the general population. Future health promotion interventions should highlight the disadvantages of joint cigarette and waterpipe smoking targeting adults and especially females.

Effectiveness of the Biography and Life Storybook for Nursing Home Residents: A Quasi-Experimental Study

There are currently limited studies that have examined the use of the biography and life storybook (BLSB) among the Asian older adult populations in the long-term care setting. This quasi-experimental study aimed to examine its impact on life satisfaction scores, depression, and quality of life among nursing home residents in Singapore. Two wards were assigned to either the intervention or control group. The intervention group was assigned to the BLSB intervention, which comprised eight nurse-facilitated structured sessions over three months and their usual daily activities, whereas the control group was assigned to the routine activities. A total of 74 nursing home residents completed the study, with 37 in each group. The BLSB intervention improved depression, quality of life, and life satisfaction for nursing home residents in Singapore, with significant results observed across all three outcomes over the 3-month period. The study findings support the use of BLSB as an effective reminiscence-based intervention for older adults in an Asian nursing home setting.

Needs and Needs Communication of Nursing Home Residents with Depressive Symptoms: A Qualitative Study

Nursing home residents are affected by depressive symptoms more often than elders living at home. There is a correlation between unmet needs and depression in nursing home residents, while met needs positively correlate with greater satisfaction and well-being. The study aims to examine the needs of nursing home residents with depressive symptoms and the communication of those needs, as no previous study has explicitly addressed the needs of this group of people and the way they are communicated. We conducted semi-structured interviews with 11 residents of three nursing homes and analyzed them using content-structuring content analysis. The residents reported diverse needs, assigned to 12 categories. In addition, barriers such as health impairments prevented the fulfillment of needs. As to the communication of needs, various interlocutors, facilitators, and barriers were identified. The findings reveal that residents can express their needs and are more likely to do so if the interlocutors are patient and take them seriously. However, lack of confidants, missing or non-functioning communication tools, impatience and perceived lack of understanding on the part of caregivers, and residents’ insecurities limit communication of needs.

Person-Centred Care Transformation in a Nursing Home for Residents with Dementia

Background

Conventional nursing homes in Singapore adopt an institutional and medical model of care with a focus on safety and risk management. As such, less regard is placed on upholding the dignity and autonomy of the resident, which compromises quality of care and the well-being of the resident. Today, person-centred care (PCC) has become synonymous with high-quality care that sustains the well-being and personhood of the care recipient.

Objectives

To describe the model of PCC adopted by a nursing home, Apex Harmony Lodge (AHL), with a logic model and evaluate outcomes on residents' well-being, care quality, and staff attrition by comparing pre-PCC initiation (2015) to post-implementation (2016).

Methods

Male residents in a 30-bed assisted living facility for persons with dementia in AHL were assessed using Dementia Care Mapping. Residents' well-being and staff attrition were measured before and after PCC implementation.

Results

There were statistically significant improvements in resident well-being (Δ = 0.44, p = 0.029), Positive Engagement Potential (Δ = 0.17, p = 0.002), and Occupational Diversity (Δ = 0.12, p = 0.014) in 2016. Withdrawal and Passive Engagement in the residents were reduced significantly as were Care Detractors. There was also a 55% reduction in staff attrition rates post-PCC.

Conclusions

Post-PCC implementation, the outcomes indicate a superior quality of care, enhanced resident well-being, and better staff retention. The AHL PCC model could serve as a roadmap for other nursing homes aspiring to raise the quality of care and influence long-term care standards and regulations for policy makers and legislators.

Social Connection in Long-Term Care Homes: A Scoping Review of Published Research on the Mental Health Impacts and Potential Strategies During COVID-19

Objectives

Good social connection is associated with better health and wellbeing. However, social connection has distinct considerations for people living in long-term care (LTC) homes. The objective of this scoping review was to summarize research literature linking social connection to mental health outcomes, specifically among LTC residents, as well as research to identify strategies to help build and maintain social connection in this population during COVID-19.

Design

Scoping review.

Settings and Participants

Residents of LTC homes, care homes, and nursing homes.

Methods

We searched MEDLINE(R) ALL (Ovid), CINAHL (EBSCO), PsycINFO (Ovid), Scopus, Sociological Abstracts (ProQuest), Embase and Embase Classic (Ovid), Emcare Nursing (Ovid), and AgeLine (EBSCO) for research that quantified an aspect of social connection among LTC residents; we limited searches to English-language articles published from database inception to search date (July 2019). For the current analysis, we included studies that reported (1) the association between social connection and a mental health outcome, (2) the association between a modifiable risk factor and social connection, or (3) intervention studies with social connection as an outcome. From studies in (2) and (3), we identified strategies that could be implemented and adapted by LTC residents, families and staff during COVID-19 and included the articles that informed these strategies.

Results

We included 133 studies in our review. We found 61 studies that tested the association between social connection and a mental health outcome. We highlighted 12 strategies, informed by 72 observational and intervention studies, that might help LTC residents, families, and staff build and maintain social connection for LTC residents.

Conclusions and Implications

Published research conducted among LTC residents has linked good social connection to better mental health outcomes. Observational and intervention studies provide some evidence on approaches to address social connection in this population. Although further research is needed, it does not obviate the need to act given the sudden and severe impact of COVID-19 on social connection in LTC residents.

Effect of pain on depression among nursing home residents: Serial mediation of perceived social support and self-rated health. A cross-sectional study

Aim

The aim of this study was to investigate how perceived social support and self‐rated health together could mediate the relationship between pain and depression among Chinese nursing home residents with pain.

Methods

The study was conducted in 38 nursing homes in 13 cities in China. A convenience sample of 2154 older adults responded to the questionnaire survey. A mediation analysis was performed on the data of 990 participants with pain. The data were collected by a questionnaire consisting of socio‐economic and demographic characteristics, the Geriatric Depression Scale‐15, the Multidimensional Scale of Perceived Social Support, Self‐rated Health Scale and the Numerical Rating Scale of pain. The sample was subdivided by sex. Descriptive analysis, t‐tests, chi‐squared tests, Mann–Whitney U‐tests, Spearman correlation analyses and the bootstrap method were used to analyze data.

Results

The prevalence rate of pain and depression among nursing home residents were 46.0% and 20.7% respectively. Pain, perceived social support and self‐rated health were all significantly correlated with depression (r = 0.217, P < 0.01; r = −0.216, P < 0.01; r = 0.385, P < 0.01, respectively). Perceived social support and self‐rated health independently and in series partly explained the relationship between pain and depression.

Conclusions

The results of the study showed that pain was associated with low perceived social support first, and then poor self‐rated health, which was in turn related to the development of depression among nursing home residents with pain. For nursing home residents, perceived social support and self‐rated health as an internal resource can affect the ability to overcome the suffering of pain and reduce the level of depression.

Prevalence and related influencing factors of depression symptoms among empty-nest older adults in China

BACKGROUND

The phenomenon of empty-nest older adults has raised growing concerns in contemporary Chinese society. In this study, we examined the prevalence and related influencing factors of depression symptoms among empty-nest older adults in China at a national level.

METHODS

The database of the 2015 China Health and Retirement Longitudinal Study (N = 8549, aged ≥ 60) was used. The 10-item version of the Centre for Epidemiologic Studies Depression Scale was employed to measure depression symptoms.

RESULTS

The prevalence of depression symptoms was 34.7 % for empty-nest respondents, 32.2 % for respondents living with a spouse only and 43.4 % for those living alone. Multivariable logistic regression indicated that, compared with the non-empty-nest respondents, older adults living alone were more susceptible to depression symptoms (OR 1.194, 95 %CI 1.016-1.405) whereas older adults living with a spouse only were not exposed to an elevated probability of being depressed (OR 0.945, 95 %CI 0.847-1.055). Multivariable logistic regression also suggested that empty nesters who were female, lived in rural areas, had a lower frequency of children's visits, had lower socioeconomic status and had worse physical health conditions were more vulnerable to depression symptoms.

CONCLUSIONS

The association between empty-nest status and later-life depression is mixed. More concerns should be raised about the mental health of empty nesters living alone. Increased attention should also be paid to empty nesters who are female, rural residents and have low contact frequency with their children, disadvantaged socioeconomic status and poor physical health conditions.

Relationship of zinc status with depression and anxiety among elderly population

BACKGROUND & AIMS

Population aging is a global challenge. Old populations are prone to zinc deficiency. This study aimed to determine the association of zinc status with depression and anxiety among men and women aged 60+ years old.

METHODS

In this cross-sectional study, 297 elderly participants (144 males and 153 females) were studied. The dietary and serum zinc were assessed using a three-day dietary record and an auto-analyzer, respectively. Depression and anxiety were measured using Geriatric Depression Scale and Hamilton Anxiety Rating Scale, respectively. Chi-squared test was used to compare qualitative variables. Multiple logistic regression analysis was conducted to assess relationship between zinc status and depression/anxiety.

RESULTS

The total zinc deficiency based on serum values was 23.2%. Dietary intake of zinc in 72.4%of participants was less than of the Estimated Average Requirement (EAR). The total depression prevalence was 42.2%. Moreover, 52.5% of the participants suffered from anxiety. The odds of depression among participants in the third tertile of serum zinc concentration was 51% lower than those in the first tertile (OR = 0.49, CI = 0.25-0.96, p = 0.03). No significant relationship was found between zinc intake and depression. Furthermore, serum or dietary zinc levels were not related to anxiety.

CONCLUSIONS

This study showed a considerable zinc deficiency and depression/anxiety in the old population. A significant relation was found between serum zinc concentration and depression. Further surveys, especially cohort studies and clinical trials are needed to confirm these results.

Prevalence and correlates of major depressive disorder, bipolar disorder and schizophrenia among nursing home residents without dementia: systematic review and meta-analysis

BACKGROUND

The elderly population and numbers of nursing homes residents are growing at a rapid pace globally. Uncertainty exists regarding the actual rates of major depressive disorder (MDD), bipolar disorder and schizophrenia as previous evidence documenting high rates relies on suboptimal methodology.

AIMS

To carry out a systematic review and meta-analysis on the prevalence and correlates of MDD, bipolar disorder and schizophrenia spectrum disorder among nursing homes residents without dementia.

METHOD

Major electronic databases were systematically searched from 1980 to July 2017 for original studies reporting on the prevalence and correlates of MDD among nursing homes residents without dementia. The prevalence of MDD in this population was meta-analysed through random-effects modelling and potential sources of heterogeneity were examined through subgroup/meta-regression analyses.

RESULTS

Across 32 observational studies encompassing 13 394 nursing homes residents, 2110 people were diagnosed with MDD, resulting in a pooled prevalence rate of 18.9% (95% CI 14.8-23.8). Heterogeneity was high (I2 = 97%, P≤0.001); no evidence of publication bias was observed. Sensitivity analysis indicated the highest rates of MDD among North American residents (25.4%, 95% CI 18-34.5, P≤0.001). Prevalence of either bipolar disorder or schizophrenia spectrum disorder could not be reliably pooled because of the paucity of data.

CONCLUSIONS

MDD is highly prevalent among nursing homes residents without dementia. Efforts towards prevention, early recognition and management of MDD in this population are warranted.

Correlation Between Depressive Symptoms And Quality Of Life, And Associated Factors For Depressive Symptoms Among Rural Elderly In Anhui, China

Purpose

We aimed to assess the current status of depressive symptoms and quality of life (QoL) among rural elderly in central China (Anhui Province) and explore their correlation and associated factors for depressive symptoms.

Methods

A multi-stage random sampling method was used to obtain 3349 participants (aged ≥60): 1206 poor and 2143 non-poor. The 30-item Geriatric Depression Scale (GDS-30) and five-dimensional European quality of health scale (EQ-5D) were employed to evaluate depressive symptoms and QoL, respectively.

Results

The prevalence of depressive symptoms was 52.9%, and that in the poor group (62.3%) was significantly higher than the non-poor group (47.6%). The GDS-30 score was 12.40 ± 7.089, and the poor group scored significantly higher (14.045 ± 6.929) than the non-poor group (11.472 ± 7.011). The EQ-5D score was 0.713 ± 0.186, and the poor group (0.668 ± 0.192) scored significantly lower than the non-poor group (0.738 ± 0.178). There was a significant negative correlation between depressive symptoms and QoL (r = −0.400, P-value <0.05). The following factors were associated with depressive symptoms: poverty, low EQ-5D score, female gender, older age, illiteracy, unemployed, chronic diseases, and hospitalization in previous year.

Conclusion

Rural elderly in central China have a high prevalence of depressive symptoms and low QoL. Poverty was associated with a higher prevalence of depressive symptoms and lower QoL.

The thriving of older people assessment scale: Psychometric evaluation and short-form development

AIM

To evaluate the psychometric properties and performance of the 32-item Thriving of Older People Assessment Scale (TOPAS) and to explore reduction into a short-form.

BACKGROUND

The 32-item TOPAS has been used in studies of place-related well-being as a positive measure in long-term care to assess nursing home resident thriving; however, item redundancy has not previously been explored.

DESIGN

Cross-sectional study.

METHOD

Staff members completed the 32-item TOPAS as proxy raters for a random sample of Swedish nursing home residents (N = 4,831) between November 2013 - September 2014. Reliability analysis, exploratory factor analysis and item response theory-based analysis were undertaken. Items were systematically identified for reduction using statistical and theoretical analysis. Correlation testing, means comparison and model fit evaluation confirmed scale equivalence.

RESULTS

Psychometric properties of the 32-item TOPAS were satisfactory and several items were identified for scale reduction. The proposed short-form TOPAS exhibited a high level of internal consistency (α = 0.90) and strong correlation (r = 0.98) to the original scale, while also retaining diversity among items in terms of factor structure and item difficulties.

CONCLUSION

The 32-item and short-form TOPAS' indicated sound validity and reliability to measure resident thriving in the nursing home context.

IMPACT

There is a lack of positive life-world measures for use in nursing homes. The short-form TOPAS indicated sound validity and reliability to measure resident thriving, providing a feasible measure with enhanced functionality for use in aged care research, assessments and care planning for health-promoting purposes in nursing homes.

Psychosocial and physical factors associated with depression in older adults living in studio apartments: A cross-sectional study of a multi-ethnic Asian population

Background:

There is a rapidly ageing population globally, leading to a rise in subsidised public housing in many countries for older adults. According to the World Health Organisation, depression is the most prevalent mental disorder in older adults. There is a gap in literature on the factors associated with depression in those residing in studio apartments for older adults, characterised by small living spaces and isolated community settings.

Objective:

The aim of this study was to examine the associations between socio-demographic variables, social support, self-perceived health and mental status, life satisfaction, exercise, physical functioning, chronic conditions, and the use of eldercare services, with depressive symptoms.

Methods:

We utilised a cross-sectional study of older adults aged ⩾55 years residing in Singapore’s studio apartments. Multivariable logistic regression was applied.

Results:

Widowhood was associated with depressive symptoms, compared to being married or having a domestic partner (adjusted odds ratio (AOR) = 1.70, 95% confidence interval (CI) = 1.01 to 2.86). Odds of depressive symptoms were associated with difficulty bathing and showering (AOR = 3.74, 95% CI = 1.06 to 13.21). Depressive symptoms were associated with cataract (AOR = 1.67, 95% CI = 1.01 to 2.77) and urinary tract disorder (AOR = 4.70, 95% CI = 1.21 to 18.26). There were dose-response relationships between higher odds of depressive symptoms and poorer social support, self-perceived mental health, life satisfaction, and exercise behaviour ( p for trend < 0.001).

Conclusion:

Factors including widowhood, physical functioning difficulty, chronic conditions, low social support, low self-perceived mental health, poor life satisfaction, and lack of exercise behaviour, were associated with depressive symptoms in older adults residing in studio apartments. More attention is needed to care for the psychosocial and physical needs of older adults in studio apartments.

Intersectional cohort change: Disparities in mobility limitations among older Singaporeans

Mobility is fundamental to independent living, but past research on physical function and mobility in older adults has not considered both intersectional social identities and cohort change in tandem. This paper utilizes data on mobility limitations from older adults in multi-ethnic Singapore to test whether cohort change varies simultaneously by gender and ethnicity. Panel data (n = 9334 person-years) collected over six years (2009-2015) were used to estimate aging vector models. Findings show that after adjusting for all covariates, Malay and Indian males in later-born cohorts have an increased number of mobility limitations compared to earlier-born cohorts. While a similar trend was also found for Chinese males and females in unconditional models, these were fully mediated by sociodemographic and health variables. These results highlight the importance of considering cohort change at the intersection of gender and ethnicity, bringing attention to possible inequities between ethnic groups.

Association of Comorbid Burden and Patient Outcomes of Residents With Dementia in Jordanian Nursing Homes

Medical and psychiatric comorbidity in individuals with dementia is often associated with serious adverse health outcomes. Using a convenience sample of 76 residents with dementia in Jordanian nursing homes, the current study aimed to examine the relationship among comorbid burden, ability to verbally self-report symptoms, severity of dementia, and patient outcomes of pain and agitation. Comorbid burden and ability to verbally self-report symptoms were found to be significant predictors of patient outcomes of pain and agitation. However, the ability to verbally self-report symptoms did not explain the relationship between comorbid burden and patient outcomes. Nurses must understand the impact of comorbid burden and the ability to verbally self-report symptoms regarding pain and agitation in individuals with dementia.

Physical diagnoses in nursing home residents - is dementia or severity of dementia of importance?

Background

Dementia and physical morbidity are primary reasons for nursing home admission globally. However, data on physical morbidity in nursing home residents with and without dementia are scarce. The first aim of the present study was to explore whether presence and severity of dementia were related to the number of physical diagnoses in nursing home residents. The second aim was to explore if the severity of dementia was associated with having registered the most frequent complexes of physical diagnoses when controlling for physical health and demographic factors.

Methods

A total of 2983 Norwegian nursing home residents from two cross-sectional samples from 2004/2005 and 2010/2011 were included in the analysis. By the use of assessment scales, the severity of dementia (Clinical Dementia Rating), physical health (General Medical Health Rating), activities of daily living (Physical Self-Maintenance Scale) and neuropsychiatric symptoms (Neuropsychiatric Inventory Nursing Home) were determined. Physical diagnoses and medications were assembled from the medical records. The physical diagnoses were categorized into complexes, using the ICD-10 chapters. Linear mixed models and generalized linear mixed models were estimated.

Results

Residents with dementia were registered with fewer physical diagnoses than residents without dementia. The frequency of physical diagnoses decreased with increasing severity of dementia. Cardiovascular, musculoskeletal and endocrine, nutritional and metabolic diagnoses were the most common complexes of physical diagnoses in individuals with and without dementia. The odds of having cardiovascular and musculoskeletal diagnoses increased for males and decreased for females with increasing severity of dementia, in contrast to endocrine diagnoses where the odds increased for both genders.

Conclusion

Increasing severity of dementia in nursing home residents may complicate the diagnostics of physical disease. This might reflect a need for more attention to the registration of physical diagnoses in nursing home residents with dementia.

Loneliness and depression symptoms among the elderly in nursing homes: A moderated mediation model of resilience and social support

Loneliness has been identified as a risk factor for depressive symptoms. Resilience and social support have been regarded as underlying protective factors. Little is known about the complex relations among these factors in the nursing home elderly. This study aimed to assess the prevalence of depressive symptoms, explore whether resilience mediated the association between loneliness and depressive symptoms, and investigate whether social support moderated the indirect or direct effect of mediation model. A total of 323 nursing home elderly were recruited in Jinan City, China. Loneliness, resilience, social support and depressive symptoms were measured. Results shown the association between loneliness and depressive symptoms was partially mediated by resilience. Besides, the indirect effect of the mediation model was moderated by social support. When the level of social support was higher, the indirect effect of loneliness on depressive symptoms through resilience was weaker. The incidence of depressive symptoms among the nursing home elderly could not be neglected. The findings suggest that interventions, such as improving resilience and social support, may help break the link between loneliness and depressive symptoms among the elderly in nursing homes.

Prevalence of depressive symptoms in older nursing home residents with intact cognitive function in Taiwan

The investigators aimed to explore the prevalence of depressive symptoms and associated factors among older residents with intact cognitive function in nursing homes in Taiwan. A cross-sectional descriptive and correlational research design was used. A convenience sample of 178 older residents without cognitive impairment was recruited from 36 nursing homes in Southern Taiwan. The questionnaires included demographic data; the Barthel Index, which assesses the ability to perform activities of daily living; and the Geriatric Depression Scale Short Form. Among older residents in nursing homes with intact cognitive function, 39.3% had depressive symptoms. Age, religion, previous living status, previous working status, being totally dependent in physical function, and being severely dependent in physical function were significant predictors of depressive symptoms among cognitively intact older residents. The findings highlight the critical mental healthcare issues among older residents with intact cognitive function in nursing homes. Practical strategies for preventing the occurrence of depressive symptoms and caring for those who have depressive symptoms should be developed, especially for younger or dependent older residents or residents who have never been employed, have no religious beliefs, or have lived alone before they moved into an institution.

Psychiatric consultation in the nursing home: reasons for referral and recognition of delirium

Objective

To describe the behavioural and psychiatric problems found in nursing home psychiatric referrals in the Dublin South city area.

Methods

We undertook two consecutive surveys of nursing home referrals to the St James’s Hospital psychiatry of old age service over a 2-year period. During the second survey a new clinical nurse specialist was specifically appointed to manage the seven nursing homes included in the study.

Results

The most common reason for referral during survey one was uncooperative/aggressive behaviour (22%). For survey two, patients were most commonly referred for low mood (31%) or agitation (29%). During survey one, the majority of patients assessed were diagnosed with behavioural and psychological symptoms of dementia (41%). This was also a prevalent diagnosis during survey two, affecting 27% of those referred. Only 7% of patients were considered to be delirious during survey one. This rose to 31% the following year making it the most common diagnosis during survey two. Over the 2-year study period, 7% of referred patients were diagnosed with depression. In terms of prescribing practices, the discontinuation rate of antipsychotic mediation following psychiatric input was 13% in survey one. By survey two, this had risen to 47%.

Conclusions

Delirium is often undetected and untreated in nursing homes. Residents presenting with psychiatric symptoms should undergo routine bloods and urinalysis prior to psychiatric referral. Dedicated input from trained psychiatric nursing staff can lead to both an improvement in the recognition of delirium and reduced prescribing rates of antipsychotic medication.

Depressive Symptoms and Associated Factors in Institutionalized Elderly

Background/Study Context: Depression is a common psychiatric disorder in the elderly that leads to a decrease in quality of life and functional impairment, among other health problems. The study of depressive symptoms in institutionalized elderly is scarce in Latin America and can contribute to plan prevention and treatment actions in order to improve health conditions for the residents as well as quality of life. Therefore, the aim of this study is to determine the prevalence of depressive symptoms and identify its associated factors in institutionalized elderly.

METHODS

A cross-sectional study is presented herein, carried out in 10 nursing homes of the municipality of Natal (Northeast Brazil). All individuals over the age of 60 were included. The Geriatric Depression Scale (GDS-15) was applied to verify the depressive symptoms, as well as sociodemographic variables related to the institution and health conditions (comorbidities, medication, body mass index, level of physical activity, mobility, and functional and cognitive capacities). Bivariate analysis was carried out using the chi-square Pearson's test (or Fisher's test) and the linear trend chi-square. Finally, logistic regression was utilized for multivariate analysis.

RESULTS

The final sample was constituted of 142 elderly, mostly of the female sex (78.9%), with an average age of 79.3 (SD: 8.2). Of these, 65 individuals presented depressive symptoms, with a 45.77% prevalence (95% confidence interval [CI]: 37.80-53.97%). The final model verified an association between the presence of depressive symptoms and functional impairment, prevalence ratio (PR) = 1.58 (95% CI: 1.04-2.42), and arterial hypertension, PR = 1.57 (95% CI: 1.07-2.31), adjusted by fecal incontinence, sex, and age.

CONCLUSION

Depressive symptoms were present in almost half of the sample of institutionalized elderly, and this condition was associated with functional impairment and arterial hypertension. The results of this work indicate the importance of monitoring depression as well as intervening on these modifiable aspects, to avoid the cascade of negative outcomes associated with this disease and also improve the quality of life of this population group.

The mediating role of sleep quality on the relationship between perceived stress and depression among the elderly in urban communities: a cross-sectional study

OBJECTIVE

This study aims to investigate the relationship between perceived stress, sleep quality, and depression among the elderly in urban communities, and further to determine whether sleep quality can serve as a mediator among the elderly in urban communities.

STUDY DESIGN

A cross-sectional survey.

METHODS

Between May and July in 2015, we conducted a cross-sectional survey among 1050 community residents aged ≥60 years from Liaoning province, China. The Perceived Stress Scale, Pittsburgh Sleep Quality Index, and Epidemiological Studies Depression Scale were used to estimate perceived stress, sleep quality, and depression, respectively. The data were analyzed with correlation, multiple linear regression, and structural equation modeling.

RESULTS

Of the 1050 participants surveyed, 1032 completed responses were ultimately acquired (98.3% effective response rate) and were included in the data analysis. Results revealed that the scores of perceived stress and sleep quality were positively correlated with Epidemiological Studies Depression Scale score. Sense of uncontrol, sense of nervous, sleep duration, and daytime dysfunction were identified as significant predictors of depression among the elderly. The effect of perceived stress on depression was partly mediated by sleep quality.

CONCLUSIONS

Our study reveals that not all dimensions of sleep quality are relevant factors affecting depression in the elderly, and there may be partial mediation effects of sleep quality, mainly through sleep duration and daytime dysfunction, within the impact of perceived stress on depression. This signifies that coping with perceived stress can be expected to ameliorate the severity of depression in the elderly by the intermediary role of sleep quality as well as the direct effect. However, longitudinal research is needed to confirm these findings and to investigate other mediators between perceived stress and depression among the elderly.

Memory and Learning Complaints in Relation to Depression among Elderly People with Multimorbidity

Although current models of care are generally well-suited to providing treatment for individual medical conditions, the emergence of multimorbidity is becoming a serious concern for practitioners and policy researchers, particularly in developing countries. The challenges of tackling multimorbidity are further compounded when the multimorbidity co-occurs with psychiatric conditions such as cognitive and depressive disorders. Understanding the relationships between multimorbidity and psychiatric illnesses is therefore of considerable clinical importance. In the present study, we cross-sectionally examined whether multimorbidity has an association with perceived cognition-including memory, learning complaints, and depression-among elderly population in South Africa. Study subjects were 422 men and women aged 50 years and older. The prevalence of arthritis, asthma, cancer, diabetes, heart disease, chronic lung disease, hypertension, and stroke was respectively 31.5, 7.3, 1.7, 10.2, 1.2, 1.7, 52.1, and 31.5%, and that of multimorbidity was 30.8%. In the multivariate analysis, women with multimorbidity were 4.33 times (OR = 4.33, 95%CI = 2.96⁻14.633) more likely to report memory complaints. The odds of diagnosed depression were 1.4 times (OR = 1.4, 95%CI = 1.045⁻5.676), and the odds of self-reported depression were 1.7 times (OR = 1.7, 95%CI = 1.41⁻2.192) higher among women who had multimorbidity compared with those who had no morbid conditions. However, the association was not significant among men. Overall, the findings suggest that the occurrence of multimorbidity warrants special attention, especially regarding its compounding effects on psychological health. The findings need to be replicated through longitudinal studies that consider a broader range of chronic conditions.

Sociodemographic profile, family aspects, perception of health, functional capacity and depression in institutionalized elderly persons from the north coastal region of Rio Grande do Sul, Brazil

Abstract Objective: to describe sociodemographic and family relationships, health status, depression and degree of functional capacity in institutionalized elderly persons in eleven long-term care facilities for the elderly in the north coastal region of Rio Grande do Sul, Brazil. Methods: a cross-sectional study was carried out of 60 institutionalized elderly persons without cognitive impairment, confirmed by a score greater than 13 in the Mini Mental State Exam. Questionnaires were used to obtain data on sociodemographic conditions, family relationships, and self-perception of health. Functional capacity was evaluated with the Barthel Index and the Geriatric Depression Scale was applied. Results: A predominance of women, widowed and single, with a of low level of education and precarious financial status, most of whom who did not have children, was observed. The elderly persons complained about difficulty walking (38.3%), generalized pain (16.7%) and vision problems (13.3%). The majority (95%) reported suffering from two to three chronic diseases and making daily use of three or more drugs. Although 55% of the participants presented depressive symptoms and morbidity, they reported functional independence and 50% rated their health as good. Conclusions: These data contributed to the knowledge of the health status and functional capacity of these institutionalized elderly persons, aiming to improve the care provided to this public.

Exploring Individual, Family, and Extrafamilial Factors Associated With Depression Among Elderly Residents of Care Settings

This study investigated simultaneously the associations among individual, family, and extrafamilial factors and depression among elderly residents of care settings in Taiwan. The data for this study were obtained from the Vulnerability and Social Exclusion among Different Groups of Disadvantaged Elderly in an Aging Society: Phenomena and Strategies (1/2) project, which was conducted in Taipei City and Taipei County in 2007. We applied multiple regression procedures to a sample of 327 residents of care settings (48.3% women) who were mild physical impairment or physically independent and cognitively clear for determining factors associated with depression and their cumulative effects. We discovered that 24.5% of the residents were depressed. Physical mobility, number of chronic diseases, and self-assessed health status were significantly associated factors in all models. In the final model, we determined that one third of extrafamilial factors were significantly associated with depression, after controlling for all other variables. In addition, we observed an overall trend of increased mean scores of depression with an increase in the number of risk factors. The results imply that interventions aimed at preventing depression in elderly persons living in care settings, particularly persons with multiple risk conditions such as impaired physical mobility and medical comorbidities, should be designed to include extrafamilial elements. Establishing strong connections between elderly care setting residents and the institutional and neighborhood environments can help prevent depression.

Residents' engagement in everyday activities and its association with thriving in nursing homes

AIM

To describe the prevalence of everyday activity engagement for older people in nursing homes and the extent to which engagement in everyday activities is associated with thriving.

BACKGROUND

Research into residents' engagement in everyday activities in nursing homes has focused primarily on associations with quality of life and prevention and management of neuropsychiatric symptoms. However, the mere absence of symptoms does not necessarily guarantee experiences of well-being. The concept of thriving encapsulates and explores experiences of well-being in relation to the place where a person lives.

DESIGN

A cross-sectional survey.

METHOD

A national survey of 172 Swedish nursing homes (2013-2014). Resident (n = 4831) symptoms, activities and thriving were assessed by staff using a study survey based on established questionnaires. Descriptive statistics, simple and multiple linear regression, and linear stepwise multiple regression were performed.

RESULTS

The most commonly occurring everyday activities were receiving hugs and physical touch, talking to relatives/friends and receiving visitors, having conversation with staff not related to care and grooming. The least commonly occurring everyday activities were going to the cinema, participating in an educational program, visiting a restaurant and doing everyday chores. Positive associations were found between activity engagement and thriving, where engagement in an activity program, dressing nicely and spending time with someone the resident likes had the strongest positive association with resident thriving.

CONCLUSIONS

Engagement in everyday activities can support personhood and thriving and can be conceptualized and implemented as nursing interventions to enable residents to thrive in nursing homes.

Exploring the prevalence and variance of cognitive impairment, pain, neuropsychiatric symptoms and ADL dependency among persons living in nursing homes; a cross-sectional study

BACKGROUND

Earlier studies in nursing homes show a high prevalence of cognitive impairment, dependency in activities of daily living (ADL), pain, and neuropsychiatric symptoms among residents. The aim of this study was to explore the prevalence of the above among residents in a nationally representative sample of Swedish nursing homes, and to investigate whether pain and neuropsychiatric symptoms differ in relation to gender, cognitive function, ADL-capacity, type of nursing-home unit and length of stay.

METHODS

Cross-sectional data from 188 randomly selected nursing homes were collected. A total of 4831 residents were assessed for cognitive and ADL function, pain and neuropsychiatric symptoms. Data were analysed using descriptive statistics and the chi-square test.

RESULTS

The results show the following: the prevalence of cognitive impairment was 67 %, 56 % of residents were ADL-dependent, 48 % exhibited pain and 92 % exhibited neuropsychiatric symptoms. The prevalence of pain did not differ significantly between male and female residents, but pain was more prevalent among cognitively impaired and ADL-dependent residents. Pain prevalence was not significantly different between residents in special care units for people with dementia (SCU) and general units, or between shorter-and longer-stay residents. Furthermore, the prevalence of neuropsychiatric symptoms did not differ significantly between male and female residents, between ADL capacities or in relation to length of stay. However, residents with cognitive impairment and residents in SCUs had a significantly higher prevalence of neuropsychiatric symptoms than residents without cognitive impairment and residents in general units.

CONCLUSIONS

The prevalence rates ascertained in this study could contribute to a greater understanding of the needs of nursing-home residents, and may provide nursing home staff and managers with trustworthy assessment scales and benchmark values for further quality assessment purposes, clinical development work and initiating future nursing assessments.

Technology-assisted communication in older persons in a residential care facility in South Africa

Relocation to residential care facilities by older persons (60+) can decrease their social connectedness with their primary networks. The purpose of the study was to identify the use and acceptance of technology-assisted communication to increase social connectedness in older persons (N = 103) in an urban residential care facility in South Africa. The research design was a non-experimental quantitative descriptive survey using self-administered questionnaires based on the Technology Acceptance Model. All residents were included in the study. Perceived Ease of Use, Perceived Usefulness and Attitude scales were calculated and the Behavioural Intention for technology use was measured. Participants with the highest Behavioural Intention were residents in their first year of relocation, younger participants (60–74 years), divorced participants and participants with higher educational qualifications. Perceived Ease of Use and Perceived Usefulness were low and were directly correlated. Perceived Ease of Use contributed significantly towards Attitudes concerning technology use. The overall Behavioural Intention for technology use was good (60/75) and the Technology Acceptance Model pathway was confirmed using Structural Equation Modelling. Video chat offered greatest appeal for future use.

Soybeans or Soybean Products Consumption and Depressive Symptoms in Older Residents in Rural Northeast China: A Cross-Sectional Study

OBJECTIVE

Depression is one of the most common mental disorders among elderly subjects. The purpose of this study is to estimate the prevalence of depressive symptoms and the association between soybeans consumption and depressive symptoms among older residents in rural Northeast China.

DESIGN

Cross-sectional study.

SETTING

A representative sample of the rural Northeast residents.

PARTICIPANTS

This survey was conducted from July 2012 to August 2013 which randomly selected and examined a total of 1717 residents aged ≥ 65 years from the rural Northeast China.

MEASUREMENTS

All participants completed the Patient Health Questionnaire-9 (PHQ-9). Information on demographic and lifestyle characteristics and blood biochemical indexes were collected by well-trained personnel.

RESULTS

The prevalence of depressive symptoms in the elderly was 8.9%. Women had significantly higher prevalence of depressive symptoms than men (13.3% vs.4.6%, P<0.001). Individuals consuming soybeans ≥4times/week had statically lower possibility to have depressive symptoms than those rarely consuming (3.6%vs. 12.5%, P<0.05). In addition to some conventional risk factors like sex, annual income, educational status, current smoking and chronic diseases status were associated with depressive symptoms, proper sleep duration (7-8h/d) [OR(95%CI):0.28(0.15,0.53)] and frequently consumption of soybeans or soybean products [OR (95%CI): 0.36 (0.15,0.87) for 2-3times/week and OR (95%CI):0.50 (0.34,0.74) for ≥4times/week] significantly decreased the risk of depressive symptoms among elderly in rural Northeast China.

CONCLUSION

Women had significantly higher prevalence of depressive symptoms than men in rural China. Individuals who rarely consume soybeans or soybean products are more likely to suffer depressive symptoms. Rural elderly residents should be cautiously screened to prevent or treat depression.

Increased depression risk among patients with chronic osteomyelitis

OBJECTIVE

Inflammatory processes, which provoke alternations of neurotransmitter metabolism, neuroendocrine function, and neuroplasticity in the brain, might promote depression. In depression patients who do not exhibit risk factors, including hypertension, diabetes, coronary heart disease, stroke, Parkinson's disease and dementia, particularly in young people, inflammation is a likely risk factor for depression. We explored whether chronic osteomyelitis (COM), a chronic inflammatory disease, increases depression risk.

METHODS

A Taiwanese national insurance claims data set of more than 22 million enrollees was used to select 15,529 COM patients without depression history and 62,116 randomly selected age- and gender-matched controls without depression and COM history to trace depression development for an 12-year follow-up period from January 1, 1999 to December 31, 2010. The depression risk was analyzed using the Cox proportional hazards regression model.

RESULTS

The above-mentioned risk factors for depression were more frequent in the COM cohort, who exhibited significantly higher depression risk than the control group did. Comparing only those without comorbidities, the COM group exhibited higher depression risk than the control group did (hazard ratio [HR]=3.04, 95% confidence interval [CI]: 2.55-3.62). The younger population carried even greater risk (age<45: HR=6.08, 95% CI: 1.71-7.85; age>65: HR=1.75, 95% CI: 1.39-2.19).

CONCLUSIONS

This is the first study connecting COM to increased risk of developing depression. The outcomes suggest that COM is a substantial depression predictor and call for a closer focus on these patients for more rigorous depression prevention, particularly in young people.
