Risk factors of geriatric depression in rural China based on a generalized estimating equation

Prevalence and Factors Associated With Depression and Depressive Symptoms Among Chinese Older Persons: An Integrative Review

China is the country with the largest population of older persons. Depression is the most common mental health issue among older adults, a trend expected to increase as societies continue to age. With the global increase in depression and depressive symptoms among this demographic, the resulting disease burden poses a significant challenge to health and social care systems in China. To map, summarise and examine the empirical literature on the prevalence and factors associated with depression and depressive symptoms in Chinese older adults, an integrative literature review was conducted informed by the guidelines of Whittemore and Knafl. The literature search encompassed EMBASE, SCOPUS, CINAHL, Web of Science, PubMed, PsycINFO, SocINDEX, China National Knowledge Infrastructure Database and Wanfang Database. The review included 65 studies, 29 in English and 36 in Chinese. The reported prevalence of depression or depressive symptoms in Chinese older adults was 3.78%-84.3%. Based on the biopsychosocial model, the associated factors were clustered as follows: biological factors (physical health, disability, drug effects, gender, age, diets, physical activities), psychological factors (self-esteem, coping skills, trauma, emotions, beliefs, hobbies, lifestyle) and social factors (family relationships, peers, family circumstances, school, residential areas, social support, social structure). This review synthesised research on depression among older adults in China, highlighting varying prevalence across diverse geographical locations. Given the high prevalence among certain older Chinese cohorts, the early identification and assessment of the factors associated with depression is essential to reducing disease burden. The use of the biopsychosocial model provided a theoretical lens to examine depression in this population in an integrative and holistic way. Thus, furthering understanding of the factors that require close consideration in future research and practice innovations on depression in older persons.

The Relationship Between BRI and Depressive Symptoms in Chinese Older Adults: A CLHLS-Based Study

BACKGROUND

There is a lack of research examining the association between obesity and depressive symptoms in relation to mental health. This study aimed to examine the correlation between Body Roundness Index (BRI) and depressive symptoms in elderly Chinese individuals.

METHODS

The study sample consisted of 11,842 individuals aged 65 years or older from the 2018 Chinese Longitudinal Health Longevity Survey (CLHLS) database. A multivariate logistic regression analysis was used to investigate how BRI affects the likelihood of experiencing depressive symptoms, with restricted cubic spline (RCS) curves illustrating this impact. BRI values were calculated using a predefined formula for each participant, and depressive status was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D-10).

RESULTS

The mean age of the participants was 83.1 ± 10.9 years. A non-linear relationship was identified between the BRI score and the risk of depressive symptoms. The analysis showed that for BRI scores below 5.17, there was a significant 9% increase in the risk of depressive symptoms for every 1-point decrease in BRI score. Conversely, when the BRI was 5.17 or higher, a decrease in the BRI score did not lead to a significant increase in the risk of depressive symptoms.

CONCLUSION

The study demonstrated a significant association between BRI and depressive symptoms in elderly Chinese individuals. Furthermore, it was noted that older adults classified as overweight and mildly obese had a lower likelihood of experiencing depressive symptoms and demonstrated improved mental health.

Functional dependency and cardiometabolic multimorbidity in older people: pooled analysis of individual-level data from 20 countries

BACKGROUND

The impact of cardiometabolic multimorbidity (CMM) on functional dependency (FD) is well established, but the temporal effect of FD on CMM and its mechanisms remain underexplored.

DESIGN

A multicohort study pooled data from three international cohorts.

SETTING

Data were sourced from the Health and Retirement Study (USA), the China Health and Retirement Longitudinal Study (China) and the Survey of Health, Ageing and Retirement in 18 European countries.

METHODS

FD was defined as the inability to perform basic activities of daily living (ADLs) and instrumental ADLs (IADLs) independently. CMM was defined as the co-occurrence of two or three cardiometabolic diseases, including diabetes, heart disease and stroke. Generalised estimating equation models assessed associations between FD and CMM, with mediation analysis using the Karlson, Holm and Breen method to explore the effects of hypertension and depressive symptoms. Sensitivity analyses ensured robustness.

RESULTS

The final cohort included 157 512 and 190 249 individuals for ADL and IADL analyses, respectively. CMM prevalence was 18.97% and 16.65% in these groups. FD was consistently associated with higher CMM risk, with odds ratios ranging from 1.47 (95% confidence interval: 1.33-1.63) to 1.56 (1.42-1.73). Hypertension and depressive symptoms increased CMM risk, particularly at higher FD levels. Mediation analysis showed hypertension and depressive symptoms accounted for 8.01%-16.43% and 12.04%-18.36% of the adverse effect of FD on CMM, respectively, with more pronounced effects among smokers and heavy drinkers.

CONCLUSIONS

Targeted interventions focusing on hypertension, mental wellness, lifestyle factors, and integrated treatments for FD are crucial to prevent CMM in older adults.

The mediating effect of life satisfaction between daily living abilities and depressive symptoms in the Chinese older people: evidence from CHARLS 2020

Background

Depressive symptoms represent a significant public health challenge, impacting the mental well-being of older adults. Despite this, the understanding of how activities of daily living (ADL) abilities correlate with life satisfaction and depressive symptoms among older Chinese adults remains limited.

Aims

This study aims to investigate the relationship between ADL and depressive symptoms in older people Chinese individuals, with a specific focus on examining the mediating role of life satisfaction within this context.

Methods

The study utilized data from the China Health and Retirement Longitudinal Study (CHARLS) collected in 2020. A cohort of 8,343 individuals aged 60 years and above was included. The analysis was conducted using STATA 17.0 and SPSS 26.0, employing descriptive statistics, chi-square tests, Pearson correlations, and mediation analysis using the percentile Bootstrap method with 5,000 resamples to explore the interrelations among ADL, life satisfaction, and depressive symptoms.

Results

ADL is positively correlated with life satisfaction (r = 0.129, p < 0.01) and negatively correlated with depressive symptoms (r = -0.313, p < 0.01). Additionally, life satisfaction and depressive symptoms are negatively correlated with each other (r = -0.360, p < 0.01). In the model of the mediating effect, ADL directly, significantly and negatively predicts depressive symptoms in the Chinese older people (β = -0.193, t = -17.827, p < 0.001). After incorporating life satisfaction into the regression equation, the direct predictive effect of ADL on depressive symptoms remains significant (β = -0.177, t = -17.099, p < 0.001); furthermore, ADL has a significant positive predictive effect on life satisfaction (β = 0.007, t = 4.959, p < 0.001) and life satisfaction significantly negatively predicts depressive symptoms (β = -2.235, t = -27.799, p < 0.001). Furthermore, the direct effect of ADL on depressive symptoms (-0.177) and its mediating effect (-0.016) account for 91.71% and 8.29% of the total effect (-0.193), respectively.

Conclusion

ADL is inversely associated with the risk of depressive symptoms among older people Chinese individuals, with life satisfaction serving as a significant mediator in this relationship. Interventions aimed at improving life satisfaction in older people individuals with ADL impairments may effectively reduce or prevent the onset of depressive symptoms.

Relationship between social participation and depressive symptoms in patients with multimorbidity: the chained mediating role of cognitive function and activities of daily living

OBJECTIVE

The potential mechanisms linking social participation and depressive symptoms in Chinese individuals with multimorbidity are not yet fully understood. This study aims to explore how cognitive function and activities of daily living (ADLs) mediate the relationship between social participation and depressive symptoms in individuals with multimorbidity.

METHODS

We selected 3782 participants with multimorbidity from the 2018 China Health and Retirement Longitudinal Study. Data related to social participation, cognitive function, ADLs, and depressive symptoms were extracted. Regression and Bootstrap analyses were used to explore the sequential mediating effects of social participation, cognitive function, ADLs, and depressive symptoms.

RESULTS

(1) There was a significant correlation between social participation, cognitive function, activities of daily living, and depressive symptoms (p < 0.01). (2) Social participation directly affected depressive symptoms (β = -0.205, p < 0.05). (3) Cognitive function (β = -0.070, p < 0.01) and activities of daily living (β = -0.058, p < 0.01) played separate mediating roles in the effect of social participation on depressive symptoms. (4) Cognitive function and activities of daily living had a chain-mediated role in the relationship between social participation and depressive symptoms in patients with multimorbidity (β = -0.020, p < 0.01).

CONCLUSION

A chained mediating effect was found between cognitive function, ADLs, social participation, and depressive symptoms in patients with multimorbidity. Social participation was found to improve the cognitive function of patients with multimorbidity, which in turn enhanced their daily life activities and ultimately alleviated their depressive symptoms.

Decomposition and comparative analysis of differences in depressive symptoms between urban and rural older adults: Evidence from a national survey

OBJECTIVES

The aim of this study was to investigate the factors influencing urban-rural differences in depressive symptoms among old people in China and to measure the contribution of relevant influencing factors.

DESIGN

A cross-sectional research. The 2018 data from The Chinese Longitudinal Health Longevity Survey (CLHLS).

SETTING

Twenty-three provinces in China.

PARTICIPANTS

From the 8th CLHLS, 11,245 elderly participants were selected who met the requirements of the study.

MEASUREMENTS

We established binary logistic regression models to explore the main influencing factors of their depressive symptoms and used Fairlie models to analyze the influencing factors of the differences in depressive symptoms between the urban and rural elderly and their contribution.

RESULTS

The percentage of depressive symptoms among Chinese older adults was 11.72%, and the results showed that rural older adults (12.41%) had higher rates of depressive symptoms than urban (10.13%). The Fairlie decomposition analysis revealed that 73.96% of the difference in depressive symptoms could be explained, which was primarily associated with differences in annual income (31.51%), education level (28.05%), sleep time ( - 25.67%), self-reported health (24.18%), instrumental activities of daily living dysfunction (20.73%), exercise (17.72%), living status ( - 8.31%), age ( - 3.84%), activities of daily living dysfunction ( - 3.29%), and social activity (2.44%).

CONCLUSIONS

The prevalence of depressive symptoms was higher in rural than in urban older adults, which was primarily associated with differences in socioeconomic status, personal lifestyle, and health status factors between the urban and rural residents. If these factors were addressed, we could make targeted and precise intervention strategies to improve the mental health of high-risk elderly.

Notable dysthymia: evolving trends of major depressive disorders and dysthymia in China from 1990 to 2019, and projections until 2030

BACKGROUND

Depressive disorders have been identified as a significant contributor to non-fatal health loss in China. Among the various subtypes of depressive disorders, dysthymia is gaining attention due to its similarity in clinical severity and disability to major depressive disorders (MDD). However, national epidemiological data on the burden of disease and risk factors of MDD and dysthymia in China are scarce.

METHODS

This study aimed to evaluate and compare the incidence, prevalence, and disability-adjusted life-years (DALYs) caused by MDD and dysthymia in China between 1990 and 2019. The temporal trends of the depressive disorder burden were evaluated using the average annual percentage change. The comparative risk assessment framework was used to estimate the proportion of DALYs attributed to risk factors, and a Bayesian age-period-cohort model was applied to project the burden of depressive disorders.

RESULTS

From 1990 to 2019, the overall age-standardized estimates of dysthymia in China remained stable, while MDD showed a decreasing trend. Since 2006, the raw prevalence of dysthymia exceeded that of MDD for the first time, and increased alternately with MDD in recent years. Moreover, while the prevalence and burden of MDD decreased in younger age groups, it increased in the aged population. In contrast, the prevalence and burden of dysthymia remained stable across different ages. In females, 11.34% of the DALYs attributable to depressive disorders in 2019 in China were caused by intimate partner violence, which has increasingly become prominent among older women. From 2020 to 2030, the age-standardized incidence, prevalence, and DALYs of dysthymia in China are projected to remain stable, while MDD is expected to continue declining.

CONCLUSIONS

To reduce the burden of depressive disorders in China, more attention and targeted strategies are needed for dysthymia. It's also urgent to control potential risk factors like intimate partner violence and develop intervention strategies for older women. These efforts are crucial for improving mental health outcomes in China.

The influence of different sources of anticipated instrumental support on depressive symptoms in older adults

Objective

This study investigated how anticipated instrumental support sources and intergenerational support influence depressive symptoms in older Chinese adults.

Methods

We employed binary logistic regression on data from 7,117 adults aged ≥60 in the 2018 China Health and Retirement Longitudinal Study, controlling for gender, marital status, and self-rated health.

Results

38.89% of respondents exhibited depressive symptoms. Anticipated support from spouse and children, spouse only, children only, or other sources showed 52, 25, 46, and 40% lower odds of depression, respectively, compared with no anticipated support. Those providing financial support had 36% higher odds of depression than those without exchanges. However, those receiving financial support, receiving instrumental support, and receiving and providing financial and emotional support had 19, 14, 23, and 24% lower odds of depression.

Conclusion

Different anticipated instrumental support sources and intergenerational support influenced depression odds in older adults, suggesting potential benefits in promoting such support systems.

Study on the trajectory of depression among middle-aged and elderly disabled people in China: Based on group-based trajectory model

Background

Previous studies have shown that middle-aged and elderly adults with disabilities are at higher risk for depressive symptoms. However, there are few studies on the long-term trajectories of depressive symptoms in the Chinese middle-aged and elderly disabled population.

Objective

This study aimed to identify the different development trajectories of depressive symptoms and their influencing factors in middle-aged and elderly people with disabilities in China.

Methods

Using data from the China Health and Retirement Longitudinal Study (CHARLS) in 2011, 2013, 2015, and 2018, a longitudinal cohort was formed for the study. A total of 2053 participants underwent at least two measures of depressive symptoms, assessed using the Center for Epidemiological Studies Depression Scale (CES-D10), a depression symptom assessment scale. We constructed a Group-Based Trajectory Model (GBTM) to identify the development trajectory of depressive symptoms in 2053 middle-aged and elderly disabled individuals, screened the potential predictors using lasso regression, and analyzed the factors affecting the development trajectory of depression through multivariate logistic regression.

Results

We identified four depression symptom trajectories throughout the follow-up process: "low depressive symptom group", "worsening depressive symptom group", "relieved depressive symptom group", and "high depressive symptom group". We found that there were differences in basic characteristics among different subgroups of depression trajectory. However, middle-aged and elderly disabled women living in rural areas, with limited ADL or IADL, physical pain, poor self-reported health and self-reported memory, short sleep time, and no relatives and friends to take care of them were the key groups for the prevention and treatment of depressive symptoms.

Conclusion

There is heterogeneity in the trajectories of depressive symptoms in the Chinese middle-aged and elderly disabled population, it is necessary to focus on the characteristics of the trajectories of different subgroups.

Association between activities of daily living and depressive symptoms among older adults in China: evidence from the CHARLS

Objective

The limitation of activities of daily living (ADL) affects the mental health of older adults. We distinguished activities of daily living into basic activities of daily living (BADL) and instrumental activities of daily living (IADL) and aimed to explore the relationship between the two limitations and depressive symptoms among Chinese older adults by using nationally representative cross-sectional data.

Methods

Data from the China Health and Retirement Longitudinal Study (CHARLS, wave 4) were used, and 9,789 older adults aged 60 years and above were screened. The 10-item Center for Epidemiologic Studies Depression (CES-D-10) scale was used to measure the depressive symptoms of older adults, and a 12-item scale for ADL was used to estimate functional limitations. Generalized linear mixed-effect models were employed to examine the relationship between BADL/IADL and depressive symptoms among older adults.

Results

The prevalence of high-risk depression among older adults was 43.5%, and the rates of limitation in BADL and IADL were 19.02 and 25.29%, respectively. The prevalence of high-risk depression significantly differed among subgroups of smoking, drinking, chronic diseases, duration of sleep, having social activities or not, and the type of medical insurance. Older adults with limited BADL or IADL were at a higher risk of depression than those without limitations of BADL or IADL; BADL (OR-adjusted = 2.71; 95% CI: 2.40-3.06) and IADL (OR-adjusted = 2.68; 95% CI: 2.41-2.98) had various influences on the risk of depression in older adults.

Conclusion

ADL was a related factor in the risk of depression among older adults in China. BADL and IADL had different effects on the risk of depression, suggesting that older adults with physical function limitations might be more likely to suffer from depression.

Gender differences in depressive symptoms among Chinese older adults based on fairlie decomposition analysis

This study aimed to investigate the factors influencing depressive symptoms among Chinese older adults based on gender differences. Data from the eighth wave of Chinese Longitudinal Health Longevity Survey were used. We analyzed the influencing factors of depressive symptoms reported by older adults using the chi-squared test and logistic model. Fairlie decomposition analysis was performed to quantify the contribution level of each influencing factor. We found that 11.71 % of older adults met the CES-D-10 criteria for depressive symptoms. Females (13.89 %) reported a significantly higher level of depressive symptoms than males (9.24 %). Age, residence, sleeping time, exercise, activities of daily living functional disability, instrumental activity of daily living functional disability, and living status influenced depressive symptoms in older adults. Higher education and lower body mass index were only significant in male, whereas middle annual income and exercising were significant only in female. The Fairlie decomposition model explained the reasons for 75.64 % of the gender differences in depressive symptoms, with instrumental activity of daily living functional disability (33.60 %), age (-17.79 %), and education level (17.41 %) being major factors affecting gender differences in depressive symptoms. This is the first nationwide study to examine gender differences in depressive symptoms among older adults. These results provide a basis for relevant Chinese government departments to formulate policies to prevent and control depressive symptoms.

Decomposition and comparative analysis of depressive symptoms between older adults living alone and with others in China

Objective

This research dealt with investigating and measuring the contribution of the factors that impact depression in older adults living alone vs. those living with others (hereafter referred to as "not alone") in China.

Design

This investigation adopts a cross-sectional research design. The dataset employed for this study comprises data from 2018 the Chinese Longitudinal Health Longevity Survey (CLHLS).

Setting

The research involved data sourced from China, specifically from 23 of its provinces. From the 8th CLHLS, 12,197 older adults were selected who met the study requirements.

Measures

Binary logistic regression models were established to delve into the primary factors impacting the depressive symptoms of the individuals. Furthermore, Fairlie models were employed to assess these factors between older adults living alone and those not living alone. This approach facilitated an in-depth analysis of their respective contributions.

Results

It was observed that the demographic of Chinese older adults exhibited depressive symptoms at a rate of 11.92%. Older adults who resided alone (15.76%) exhibited a higher prevalence of depressive symptoms in comparison to their counterparts living in not-alone settings (11.15%). Employing Fairlie decomposition analysis, it was determined that this observed disparity in depressive symptoms, amounting to 55.33% of the overall difference, could be primarily attributed to distinct factors. This encompassed variance in marital status (20.55%), years of school (4.63%), self-reported local income status (7.25%), self-reported sleep status (17.56%), and self-reported health status (4.24%).

Conclusion

The resulting data indicated that depressive symptoms exhibited an elevated prevalence in older adults living alone than in those living not alone. This discrepancy was predominantly attributed to variance in socioeconomic marital status, years of school, self-reported local income status, self-reported sleep status, and self-reported health status by living alone vs. not alone. Mitigating these influential factors could help develop targeted and meticulous intervention strategies, precisely tailored to improve the mental well-being of older adults at high risk.

A Meta-Analysis of the Effects of Childhood Maltreatment on Elderly Depression

Background: The present study aimed to synthesize the effects of five types of child maltreatment (physical abuse, emotional abuse, sexual abuse, physical neglect and emotional neglect) on late-life depression.Method: Four English-language databases (Web of Science, PsycINFO and PsycARTICLES, PubMed, and Cochrane Library) and three Chinese databases (China National Knowledge Infrastructure, Wanfang Database, and Weipu Database) were systematically reviewed, and data related to the association between child maltreatment and late-life depression were extracted. Ten studies involving 30,308 older adults were included, and the effect sizes were pooled using random-effect models.Findings: Except for sexual abuse, four types of child maltreatment were found to be positively associated with late-life depression. Physical abuse, emotional abuse and physical neglect were associated with elderly depression (PA: OR = 1.73, 95% CI = 1.55-1.95, p < .001; EA: OR = 1.92, 95% CI = 1.73-2.12, p < .001; PN: OR = 2.05, 95% CI = 1.15-3.67, p < .01) at a small level, and emotional neglect was associated with elderly depression (OR = 3.25, 95% CI = 1.43-7.39, p < .001) at an approximately moderate level. Gender moderated the relationship between physical neglect, emotional neglect, and late-life depression.Conclusion: Our findings highlight the significance of child maltreatment in the development of late-life depression, and underscore the need for future research and practice to explore potential ways to address late-life depression among older adults who suffered child maltreatment.

Prevalence and factors associated with anxiety and depression among community-dwelling older adults in Hunan, China: a cross-sectional study

BACKGROUND

Older adults' psychological health is a public health issue that cannot be ignored, especially when these psychological health problems and related factors change across different social backgrounds because of rapid changes in traditions and family structures and the epidemic responses after the outbreak of COVID-19 in China. The aim of our study is to determine the prevalence of anxiety and depression and their associated factors among community-dwelling older adults in China.

METHODS

A cross-sectional study was conducted from March to May 2021 with 1173 participants aged 65 years or above from three communities in Hunan Province, China who were selected using convenience sampling. A structured questionnaire including sociodemographic characteristics, clinical characteristics, the Social Support Rating Scale (SSRS), the 7-Item Generalized Anxiety Disorder scale (GAD-7), and the Patient Health Questionnaire-9 Item (PHQ-9) was used to collect relevant demographic and clinical data and to measure social support status, anxiety symptoms, and depressive symptoms, respectively. Bivariate analyses were conducted to explore the difference in anxiety and depression based on samples' different characteristics. The multivariable logistic regression analysis was performed to test for significant predictors of anxiety and depression.

RESULTS

The prevalence of anxiety and depression were 32.74% and 37.34%, respectively. Multivariable logistic regression analysis revealed that being female, being unemployed before retirement age, lacking physical activity, having physical pain, and having three or more comorbidities were significant predictors for anxiety. Subjective social support and support utilization were significant protective factors. Regarding depression, religion, lacking physical activity, having physical pain, having three or more comorbidities were found to be significant predictors. Support utilization was a significant protective factor.

CONCLUSIONS

The study group showed a high prevalence of anxiety and depression. Gender, employment status, physical activity, physical pain, comorbidities, and social support were associated with psychological health problems of older adults. These findings suggest that governments should focus on the psychological health problems of older adults by raising community awareness of issues related to older adults' psychological health. They should also screen for anxiety and depression among high-risk groups and encourage individuals to seek supportive counseling.

Physical function, ADL, and depressive symptoms in Chinese elderly: Evidence from the CHARLS

Background

Depressive symptoms are a serious public health problem that affects the mental health of older adults. However, current knowledge of the association between ADL disability and physical dysfunction and depressive symptoms in Chinese adults is insufficient. We intend to analyze the association between physical function, ADL, and depressive symptoms in older Chinese adults.

Methods

The data obtained from the China Health and Retirement Longitudinal Survey (2015 and 2018) (CHARLS). This includes 3,431 in 2015 and 3,258 in 2018 over the age of 60. Comparing 2015 and 2018 data, multivariate logistic regression models were used to explore the relationship between physical function, ADL, and depressive symptoms in urban and rural older adults, adjusting for sociodemographic factors associated with depression in older adults.

Results

The prevalence of depressive symptoms among older adults in China was 33.8 percent in 2015 and 50.6 percent in 2018. In baseline data from 2015 and 2018, residence, gender, marital status, drinking, physical function, ADL, and self-rated health were all found to be significantly associated with depressive symptoms in older adults. The differences in physical function, ADL and depressive symptoms among older adults in 2015 and 2018 were further analyzed based on urban and rural stratification. Both physical dysfunction and ADL disability were significantly associated with depressive symptoms in rural older adults in 2015 and 2018. And in urban areas, ADL was found to be significantly associated with depressive symptoms in urban older adults. Multivariate logistic regression analysis demonstrated that ADL disability was significantly associated with depressive symptoms among older adults in both urban and rural areas. Physical dysfunction was only significant in rural areas with depressive symptoms. The alpha level was instead set to 0.05 for all statistical tests.

Conclusion

Rural, female, 60-70 years of age, primary school or below, married, non-smoking, non-drinking, physical dysfunction, ADL disability and self-rated poor health make-up a higher proportion of depressed older adults. ADL disability and physical dysfunction were more likely to be associated with depressive symptoms in rural Chinese older adults. Therefore, the physical and mental health of rural elderly should be of concern. The rural older adults should receive additional support from the government and society.

Prevalence and Family Determinants of Geriatric Depression Among Elderly People in Elderly Support Groups in Rwanda

Background

The 1994 Tutsi genocide in Rwanda significantly impacted family structure, with many people growing old alone and lacking social bonds and connections with family members. However, little is known about the contribution of the family environment to geriatric depression which was highlighted by WHO as a psychological problem with a 10% to 20% prevalence rate among the elderly worldwide. This study aims to investigate geriatric depression and associated family determinants among the elderly in Rwanda.

Methods

With a community-based cross-sectional study design, we assessed geriatric depression (GD), quality-of-life enjoyment and satisfaction (QLES), family support (FS), loneliness, neglect, and attitude toward grief in a convenience sample of 107 participants (M=72.32, SD=8.79) aged between 60 and 95 years who were recruited from three groups of elderly people supported by the NSINDAGIZA organization in Rwanda. SPSS (version 24) was used for statistical data analysis; differences across various sociodemographic variables were tested for significance by an independent t-test; the relationship between study variables was tested by Pearson correlation analysis; and multiple regression analysis was performed to model the contribution of independent variables to dependent variables.

Results

A total of 64.5% of the elderly scored above the threshold of the normal range of geriatric depression (SDS>49), with higher symptoms in women than in men. Multiple regression analysis indicated that family support and quality-of-life enjoyment and satisfaction were contributors to geriatric depression in the participants.

Conclusion

Geriatric depression was relatively common in our participants. It is associated with the quality of life and family support received. Hence, adequate family-based interventions are needed to improve the well-being of geriatric people in their respective families.

Changes and predictors of sleep quality with a 2-year follow-up in older adults according to living arrangements

OBJECTIVES

This study aimed to explore changes and predictors of sleep quality with a 2-year follow-up in Chinese elderly individuals and to further present them according to living arrangements.

METHODS

A total of 3005 individuals were effectively surveyed at baseline and at the 2-year follow-up. Generalized estimating equation (GEE) was performed to explore associations between sleep quality and predictor variables.

RESULTS

The rate of poor sleep quality was 32.6% at baseline and 27.4% at follow-up. According to living arrangements, sleep quality improved among empty nesters living as a couple (P < 0.001). After adjusting for sex, age, and other influencing factors, empty nesters living alone had poorer sleep quality (OR = 1.399, 95% CI = 1.022-1.917) than nonempty nesters. Sex, age, education, self-reported health, depression, and social support were predictors of poor sleep quality for all participants. In the subgroup analyses, self-reported physical health and body mass index (BMI) were predictors of sleep quality in the nonempty-nester group, but depression was not a predictor. Depression was a predictor of sleep quality in the empty-nester group.

CONCLUSIONS

Sleep quality was improved in this 2-year follow-up survey. However, sleep quality problems in the elderly cannot be ignored, especially empty nesters living alone. Therefore, according to living arrangements, different intervention methods should be selected to prevent and control poor sleep quality.

The Effectiveness of the Integrated Care Model among Community-Dwelling Older Adults with Depression: A Quasi-Randomized Controlled Trial

Depression is the second-leading cause of disability among older patients worldwide. This study examined the effectiveness of the Integrated Care Model (ICM) intervention in decreasing depression, suicide ideation, and psychological symptoms and improving life satisfaction among old patients with depression living in communities. The participants were allocated to either the intervention (n = 67) or control group (n = 76) from July 2018 to November 2018. All participants received the usual geriatric care for three months in eastern Taiwan. Additionally, participants in the intervention group were treated according to the ICM, including the assessment and management of health problems, improvements in spiritual and mental wellbeing, helping with activities of daily life and mobility, providing social welfare resources, and prevention of elder abuse. The patients in the experimental group showed significant improvement in the group-by-time effect on the Center for Epidemiologic Studies Depression Scale, the Brief Symptom Rating Scale, suicide ideation measures, and the Life Satisfaction Index over 18 weeks. The ICM should be included in routine geriatric care and adopted in hospitals, long-term care facilities, and communities

Prevalence and factors associated with comorbid depressive symptoms among people with low back pain in China: A cross-sectional study

BACKGROUND

Low back pain is a common medical condition among the general population that is associated with many adverse health effects when comorbid with depressive symptoms. However, little is known about depressive symptoms in the population with low back pain in China. Our study evaluated the prevalence of depressive symptoms and analyzed the factors associated with this condition in the Chinese population with low back pain.

METHODS

We conducted a cross-sectional analysis of data from the 2018 China Health and Retirement Longitudinal Study. We collected low back pain information for each participant and identified depressive symptoms using the brief version of the Center for Epidemiologic Studies Depression Scale. A wide range of sociodemographic and health-related characteristics of the subjects were extracted. We measured the prevalence of depressive symptoms comorbid with low back pain and analyzed the associated factors by multiple logistic regression.

RESULTS

A total of 5,779 respondents aged 45 and over with low back pain formed the sample, 41.8% of whom reported depressive symptoms. Multiple logistic regression analysis indicated greater vulnerability to depressive symptoms among females (OR = 1.41, 95% CI, 1.16-1.73), relatively younger persons (60-74 years: OR = 0.72, 95% CI, 0.63-0.83; ≥ 75 years: OR = 0.62, 95% CI, 0.49-0.79, reference: 45-59 years), those from the central and western regions (central: OR = 1.39, 95% CI, 1.18-1.64; western: OR = 1.56, 95% CI, 1.33-1.83), participants with extremely short sleep duration (OR = 2.74, 95% CI, 2.33-3.23), those with poor self-perceived health status (OR = 2.91, 95% CI, 2.34-3.63,), multisite pain (OR = 1.54, 95% CI, 1.20-1.98) and disability in activities of daily living (Basic: OR = 1.70, 95% CI, 1.47-1.98; Instrumental: OR = 1.95, 95% CI, 1.70-2.24).

CONCLUSION

Depressive symptoms were highly prevalent in the Chinese population ≥ 45 years with low back pain. More attention should be paid to the individuals at high-risk confirmed by this study to facilitate early identification and intervention against depressive symptoms.

Influence of Attachment Anxiety on the Relationship between Loneliness and Depression among Long-Term Care Residents

BACKGROUND

Attachment styles influence an individual's ability to maintain relationships throughout their lifespan. Insecure attachment has been associated with many aspects of mental health. The study aimed to explore the influence of attachment on loneliness and depression among old-age residents in long-term care facilities.

METHODS

A survey was conducted among residents from long term care facilities (LTC) in Thailand during the COVID-19 pandemic; 221 older people participated in the study. The mean aged was 73.60 ± 7.45 years old, and 57.5% female. All participants completed the Geriatric Depression Scale, the six-item revised version of the University of California Los Angeles Loneliness Scale, and the Revised Experience of Close Relationships questionnaire to measure depressive symptoms, loneliness, and attachment style. Hierarchical multiple regression analysis was performed to find the predictors for depressive symptoms.

RESULTS

In all, 40.7% of residents in LTC facilities experienced depression. Male sex, education, loneliness, and attachment anxiety predicted the increased level of depressive symptoms.

CONCLUSION

Loneliness was confirmed to be significantly associated with depressive symptoms, and attachment anxiety was found to be a strong predicting factor of depressive symptoms. Intervention and research regarding reducing loneliness and attachment anxiety should be promoted in LTC settings.

The relationship between depressive symptoms and activity of daily living disability among the elderly: results from the China Health and Retirement Longitudinal Study (CHARLS)

OBJECTIVE

The acceleration of population aging has brought an unprecedented impact on China's health system. This study is designed to examine the association between depressive symptoms and activity of daily living disability among the elderly in China.

STUDY DESIGN

This is a cross-sectional study.

METHODS

Data were drawn from the China Health and Retirement Longitudinal Study (CHARLS). The 10-item Center for Epidemiologic Studies-Depression (CES-D) scale was used to access depressive symptoms, and physical function was assessed by the Activity of Daily Living (ADL) scale. Multivariate logistic regression was used to assess the association between depressive symptoms and ADL among the elderly.

RESULTS

Based on a sample of 5863 elderly people over 60 years old, our results showed that 1999 elderly people are with depressive symptoms, accounting for 34.1%. The mean score of ADL among the elderly with depressive symptoms (20.65 ± 7.14) was much higher than that in those without depressive symptoms (17.40 ± 4.87). After controlling potential confounders, multivariate logistic regression showed that ADL and its specific domains including personal care, transfer, medical care, household, and managing money were associated with depressive symptoms.

CONCLUSION

This cross-sectional study provides evidence of the association between depressive symptoms and ADL disability among the Chinese elderly. As a result, prevention or reduction of ADL disability may have a positive effect on the medical care of the elderly with depressive symptoms.

Depressive symptoms and 5-year incident metabolic syndrome among older adults

Little is known regarding the association between depressive symptoms and metabolic syndrome (MetS) among older Chinese adults. This study aimed to examine the association of depressive symptoms with MetS and its components among Chinese elderly. Based on whether they showed depressive symptoms at baseline, 262 age-gender-matched participants from a community-based cohort study were included. The presence of depressive symptoms was measured using the nine-item Patient Health Questionnaire (PHQ-9). MetS was defined according to the Adult Treatment Panel III of the National Cholesterol Education Program. Linear regression and logistic regression analyses were performed to assess associations of depressive symptoms with MetS and its components. The incidence of MetS among the participants with depressive symptoms at baseline was 15.27% (20/131). The association of the presence of depressive symptoms with MetS was significant (odds ratio [OR] = 2.53, 95% confidence intervals [CI] = 1.07, 5.95). There was a negative association between depressive symptoms and hypertension (OR = 0.04, 95% CI = 0.002, 0.98). The change in mean arterial pressure varies approximately 1.03 mmHg with a 1-point change in PHQ-9 score. In this study, baseline depressive symptoms were associated with subsequent MetS. The presence of depressive symptoms was negatively associated with elevated mean arterial pressure.

Incidence trends of major depressive disorder in China: an age-period-cohort modeling study

BACKGROUND

Major depressive disorder (MDD) is a common public health problem in China. However, few studies have focused on its incidence and separated age, period, and cohort effects. This study aimed to assess the age, period, and cohort effects on the incidence trends of MDD in China between 1993 and 2017.

METHODS

The incidence data of MDD were obtained from the Global Burden of Diseases Study 2017. Age-period-cohort modeling method was used to separate the age, period, and cohort effects on MDD incidence rate.

RESULTS

The incidence number of MDD increased by 22.8% while the age-standardized incidence rate decreased by 15.6% over 25 years. Age-period-cohort analysis indicated that the net drift was -0.433% per year, with -0.486% for females and -0.385% for males. For both sexes, the local drifts were all <0 in 10 to 54 years age groups but >0 in 55 to 94 years age groups. The longitudinal age curves of MDD incidence basically showed an increasing trend, except for a subpeak at 20-24 years age group. The period rate ratio largely declined over time, except for an uptick after 2003-2007. The cohort rate ratio followed an inverted U-shaped pattern and was highest in 1951-1955 birth cohort.

LIMITATIONS

The MDD data were estimated and wide social factors were not included in the analyses.

CONCLUSION

The changes of MDD incidence rate in China are likely to be related to rapid social and economic development, and major historical events. However, the associations need to be interpreted with caution.

Gender-specific prevalence and influencing factors of depression in elderly in rural China: A cross-sectional study

BACKGROUND

With an aging population, late-life depression has been a major health problem in rural China. This study aims to explore the gender-specific prevalence of geriatric depression in rural Tianjin, its influencing factors, and to provide a scientific basis for the prevention and intervention of depression in the elderly.

METHODS

A cross-sectional study of 4,933 elderly individuals in rural Tianjin was conducted using the cluster sampling method. The independent samples t-test and chi-squared test were used to assess differences in participants' characteristics by depressive symptoms, while multiple linear regressions and multiple logistic regressions were used to analyze the potential influencing factors of depression.

RESULTS

The prevalence of geriatric depression was found to be 12.2% in the study participants (9.5% in men and 14.5% in women). Gender, education, household income, employment, living alone, social activities, physical exercise and chronic diseases were associated with depression (P<0.05). In addition to the above factors, sleep duration was also related with scores on self-rating depression scale (P<0.05).

LIMITATIONS

The study used a cross-sectional approach, so causation cannot be concluded.

CONCLUSIONS

Late-life depression is a serious mental health issue in rural China, highlighting the importance of appropriate diagnosis and treatment as a priority to improve the quality of mental health.

Built form and depression among the Chinese rural elderly: a cross-sectional study

OBJECTIVES

Few data on the association between housing structure and depression among rural elders in China are available. We examined the impact of built forms on depression.

DESIGN

This is a cross-sectional study.

SETTING

A representative sample of rural residents aged 60 years or older in China.

PARTICIPANTS

A total of 5090 older adults in 2019 in rural Suzhou, China.

OUTCOME MEASURES

Associations of built form with odds of probable and possible depression.

RESULTS

There was significant difference among elders living in varied sizes of house. Older age (vs 60-64 years: 75-79 years AdjOR, 1.737; 95% CI, 1.309 to 2.305; ≥80 years AdjOR, 2.072; 95% CI, 1.439 to 2.981), male sex (AdjOR, 0.719; 95% CI, 0.593 to 0.871), single (AdjOR, 1.303; 95% CI, 1.032 to 1.646), self-care disability (AdjOR, 4.761; 95% CI, 3.960 to 5.724), three or more chronic diseases (AdjOR, 2.200; 95% CI, 1.657 to 2.920), living alone (AdjOR, 1.443; 95% CI, 1.059 to 1.966), living in cottage (AdjOR, 1.426; 95% CI, 1.033 to 1.967), living space (vs <50 m2: 201-250 m2 AdjOR, 0.566; 95% CI, 0.359 to 0.893; >250 m2 AdjOR, 0.337; 95% CI, 0.223 to 0.511) and space per person (vs <30 m2: 30- m2 AdjOR, 0.502; 95% CI, 0.362 to 0.697; 40- m2 AdjOR, 0.473; 95% CI, 0.347 to 0.646; 50- m2 AdjOR, 0.418; 95% CI, 0.339 to 0.515) were associated with risk of depression among Chinese rural elders.

CONCLUSION

The built form was significantly and meaningfully associated with depression among Chinese rural elders. More attention should be paid to preventing mental illness among the rural elderly living in the small housing area and cottages in China.

Risk factors for depressive symptoms among older Chinese adults: A meta-analysis

BACKGROUND

The study aims to explore the risk factors for depressive symptoms among older Chinese adults.

METHODS

PubMed, PsycINFO, Cochrane Library, EMbase, Google Scholar, Chinese National Knowledge Infrastructure (CNKI), Chinese BioMedical Literature Database, and Wanfang data were searched for potentially relevant articles published before September 1^st, 2019. Stata/IC 15 was used to perform a meta-analysis and subgroup analysis to compute the pooled odds ratio.

RESULTS

The retrieve strategy yielded 11 studies that met the inclusion criteria. The total sample size was 31528 across seven districts, including Mainland China, Hong Kong, and Taiwan. Patients with depression were included in the sample size. Fourteen risk factors were extracted for at least having two or more relative studies. The combined odds ratio ranged from 0.70 to 4.75. Female, poor self-perceived financial condition, single, average and poor self-perceived health status, diabetes, adverse life events, poor social support, two or more numbers of cardiovascular diseases, and functional disability are risk factors of depressive symptoms among older Chinese adults. Fair or good social support is a protective factor.

LIMITATIONS

These findings may be somewhat limited by (i) quality of studies included, (ii) a finite number of studies met inclusion criteria.

CONCLUSIONS

Despite the methodological limitations of the studies and this meta-analysis, average or poor self-perceived health status, functional disability, poor social support, poor self-perceived financial condition, negative life events, and diabetes appear to be significant risk factors for depressive symptoms among the aged population in China. Social support can mitigate depressive symptoms.

Depression and Psychological-Behavioral Responses Among the General Public in China During the Early Stages of the COVID-19 Pandemic: Survey Study

Background

The COVID-19 pandemic has recently spread dramatically worldwide, raising considerable concerns and resulting in detrimental effects on the psychological health of people who are vulnerable to the disease. Therefore, assessment of depression in members of the general public and their psychological and behavioral responses is essential for the maintenance of health.

Objective

This study aimed to assess the prevalence of depression and the associated factors among the general public during the early stages of the COVID-19 pandemic in China.

Methods

A cross-sectional survey with convenience sampling was conducted from February 11 to 16, 2020, in the early stages of the COVID-19 outbreak in China. A self-administrated smartphone questionnaire based on the Patient Health Questionnaire-9 (PHQ-9) and psychological and behavioral responses was distributed to the general public. Hierarchical multiple regression analysis and multivariate logistic regression analysis were conducted to explore the associated factors of depression.aA cross-sectional survey with convenience sampling was conducted from February 11 to 16, 2020, in the early stages of the COVID-19 outbreak in China. A self-administrated smartphone questionnaire based on the Patient Health Questionnaire-9 (PHQ-9) and psychological and behavioral responses was distributed to the general public. Hierarchical multiple regression analysis and multivariate logistic regression analysis were conducted to explore the associated factors of depression.

Results

The prevalence of depression (PHQ-9 score ≥10) among the general public during the COVID-19 pandemic was 182/1342 (13.6%). Regression analysis indicated that feeling stressed, feeling helpless, persistently being worried even with support, never feeling clean after disinfecting, scrubbing hands and items repeatedly, hoarding food, medicine, or daily supplies, and being distracted from work or study were positively associated with depression, while social support and being calm were negatively associated with depression.

Conclusions

The general public suffered from high levels of depression during the early stages of the COVID-19 pandemic. Thus, COVID-19–related mood management and social support should be provided to attenuate depression in the general public.

Prevalence of Depressive Symptoms in the Elderly Population Diagnosed with Type 2 Diabetes Mellitus

Introduction: A sharp rise in the population of elderly people, who are more prone to somatic and mental diseases, combined with the high prevalence of type 2 diabetes mellitus and diabetes-associated complications in this age group, have an impact on the prevalence of depressive symptoms. Aim of the work: The work of the study was the evaluation of the prevalence of depressive symptoms in the elderly population diagnosed with type 2 diabetes mellitus. Materials and methods: The pilot study was conducted in 2019 among 200 people diagnosed with type 2 diabetes mellitus, aged 65 years and above, receiving treatment in a specialist diabetes outpatient clinic. The study was based on a questionnaire aimed at collecting basic sociodemographic and clinical data and the complete geriatric depression scale (GDS, by Yesavage) consisting of 30 questions. Results: The study involved 200 patients receiving treatment in a diabetes outpatient clinic. The mean age of the study subjects was 71.4 ± 5.0 years. The vast majority of the subjects (122; 61%) were women, with men accounting for 39% of the study population (78 subjects). A statistically significant difference in the GDS (p < 0.01) was shown for marital status, body mass index (BMI), duration of diabetes, and the number of comorbidities. Patients with results indicative of symptoms of mild and severe depression were found to have higher BMI, longer disease duration, and a greater number of comorbidities. There were no statistically significant differences in the level of HbA1c. Conclusions: In order to verify the presence of depressive symptoms in the group of geriatric patients with diabetes mellitus, an appropriate screening programme must be introduced to identify those at risk and refer them to specialists, so that treatment can be promptly initiated. Screening tests conducted by nurses might help with patient identification.

Interaction between worsening cognitive function and deteriorating functional status on depressive symptoms among Chinese community-dwelling elders

AIM

Cognitive impairment and functional deterioration are common in later life and often co-occur with depressive symptoms (DS). This study aims to examine the individual effects and possible interaction between worsening cognitive function (CF) and deteriorating functional status (FS) on DS using large sample, longitudinal data.

METHODS

Elderly people who completed the baseline survey of China Health and Retirement Longitudinal Study (CHARLS 2011) and the third wave survey (2015) were included. A multivariable logistic regression model was used to assess the individual effects. The relative excess risk due to interaction (RERI), the attributable proportion due to interaction (AP) and synergy index (SI) were calculated to evaluate the additive interaction.

RESULTS

Worsening CF and deteriorating FS were associated with the increase in DS, while unchanged or improved CF and FS were associated with the decrease in DS. In addition, decreased (increased) FS led to more severe (improved) DS than decreased (increased) CF. The additive interaction between worsening CF and deteriorating FS on the increase in DS was significant. The estimates and 95% CI of the RERI, AP and SI were 0.626 (0.061, 1.190), 0.222 (0.042, 0.402) and 1.526 (1.016, 2.291) respectively.

CONCLUSIONS

Both worsening CF and deteriorating FS have positive interactions with the increase in DS. It is vital to focus on DS of elderly people with worsening CF and/or FS and to adopt interventions. Geriatr Gerontol Int 2020; 20: 343-347.

Associations Between Somatic Multimorbidity Patterns and Depression in a Longitudinal Cohort of Middle-Aged and Older Chinese

OBJECTIVES

Depressive symptoms are commonly seen among patients with multiple chronic somatic conditions, or somatic multimorbidity (SMM); however, little is known about the relationships between depressive symptoms and different SMM combinations. Our study aimed to delineate the patterns of SMM and their longitudinal associations with depressive symptoms among a nationally representative sample of middle-aged and older Chinese adults.

DESIGN

We employed a longitudinal design.

SETTING AND PARTICIPANTS

Older adults (N = 10,084) aged ≥45 years from the China Health and Retirement Longitudinal Study 2011-2015 participated (mean age = 57.7 years at baseline; 53.3% men).

METHODS

Sixteen chronic somatic conditions were ascertained at baseline via questionnaires. Depression was assessed with the Center for Epidemiological Studies Depression Scale at baseline and during follow-up. Patterns of SMM were identified via exploratory factor analyses. Generalized estimating equations were used to evaluate the longitudinal associations between patterns of SMM and the presence of depressive symptoms at follow-up.

RESULTS

Compared with participants with no somatic condition, those with 1, 2, and 3 or more somatic conditions had a 21%, 66%, and 111% greater risk, respectively, for the presence of depressive symptoms. Increased factor scores for 4 patterns identified, cardio-metabolic pattern [adjusted odds ratio (AOR) 1.12, 95% confidence interval (CI) 1.06, 1.20], respiratory pattern (AOR 1.25, 95% CI 1.17, 1.33), arthritic-digestive-visual pattern (AOR 1.29, 95% CI 1.22, 1.37), and hepatic-renal-skeletal pattern (AOR 1.09, 95% CI 1.02, 1.16), were all associated with a higher risk of having depressive symptoms.

CONCLUSIONS AND IMPLICATIONS

All SMM patterns were independently associated with depression among middle-aged and older Chinese adults, with greater odds for people with comorbid arthritic-digestive-visual conditions and respiratory conditions. Clinical practitioners should treat the middle-aged and older population under a multiple-condition framework combining SMM and mental disorders.

Analysis of the Point Prevalence and Influencing Factors of Acute Stress Disorder in Elderly Patients with Osteoporotic Fractures

BACKGROUND

Increasing attention has been paid to posttraumatic affective disorders. However, orthopedic surgeons dealing with trauma often ignore the harm of such diseases.

OBJECTIVE

To investigate the point prevalence and influencing factors of acute stress disorder (ASD) in elderly patients with osteoporotic fractures (EPOFs) from the perspective of orthopedic surgeons.

PATIENTS AND METHODS

A total of 595 cases of EPOFs were treated at our hospital from January 1, 2018, to June 30, 2019. The patients meeting our inclusion criteria were assessed using a structured interview based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) criteria to verify the presence of ASD. After diagnosis, the participants were divided into two groups (those with and without ASD). The sociodemographic characteristics, disease characteristics, and Social Support Rating Scale (SSRS) scores were assessed. The chi-square test was used for univariate analysis, and multivariate analysis was performed using binary logistic regression.

RESULTS

Of the 524 participants, 32 (6.1%) met the criteria for the diagnosis of ASD. The results of the univariate analysis showed that gender, personality, living alone, monthly family income, initial fear, poor prognosis expectation, anxiety/depression, pain, and social support were associated with ASD in EPOFs (P<0.05). The multivariate regression analysis showed that isolation, low monthly family income, introversion, poor prognosis expectation, previous traumatic history, and intense pain were the main influencing factors and risk factors (OR>1) for ASD in EPOFs.

CONCLUSION

Being female, living alone, introversion, poor family income, intense initial fear, poor prognosis expectation, anxiety/depression, intense pain perception and low social support were significantly related to the occurrence of ASD in EPOFs. To achieve optimal recovery in EPOFs, orthopedic surgeons should meet both the physiological and psychological needs of the patients.

Gender-specific associations between activities of daily living disability and depressive symptoms among older adults in China: Evidence from the China Health and Retirement Longitudinal Study

PURPOSE

To evaluate the associations between BADL/IADL disability and depressive symptoms from the perspective of gender among older adults in China.

METHODS

This cross-sectional study used the data from the second wave of the China Health and Retirement Longitudinal Study (CHARLS). The sample included 3463 older adults aged 60 years and older across China. Multivariable logistic regression models were conducted.

RESULTS

Among 3463 older adults, 1240 (35.8%) were classified as depressed, the prevalence of BADL and IADL disabilities were 756 (21.8%) and 1194 (34.5%), respectively. After controlling for covariates, BADL/IADL disability was significantly associated with an increased risk of depression prevalence both in men and women among older adults. Compared with IADL independent, IADL disability was about two times more likely to develop depressive symptoms in men (OR = 2.165, 95% CI = 1.661-2.822), which was much higher than that in women (OR = 1.748, 95% CI = 1.415-2.160). In contrast, the odds of being depressed for women with BADL disability (OR = 1.824, 95% CI = 1.447-2.299) were much higher than the odds for men with BADL disability (OR = 1.791, 95% CI = 1.348-2.379).

CONCLUSIONS

Older adults with BADL/IADL disability were more likely to have depressive symptoms both for men and women. However, the associations between depressive symptoms and BADL/IADL disability were different in gender. Our results suggest that differential institutional care service and appropriate strategies for improvement in mental health are required.

Association between activities of daily living disability and depression symptoms of middle-aged and older Chinese adults and their spouses: A community based study

BACKGROUND

Little is known about the impact of activities of daily living (ADL) disability on personal and spouse depression symptoms among Chinese.

METHODS

We used data from the baseline and 2013 follow-up surveys of the China Health and Retirement Longitudinal Study, a nationally representative survey in 17,708 adults aged 45 years and older, to evaluate cross-sectional and prospective association between ADL disability and depression symptoms of subjects and their spouses. The derived basic ADL scale (BADL) and the Center for Epidemiologic Studies Depression Scale short form were utilized to assess ADL disability and depressive symptoms, respectively. Logistic regression was used to calculate odds ratio (OR) and 95% confidence interval (CI), adjusting for depression risk factors and taking into account the complex survey design and response rate.

RESULTS

There were 15,890 subjects included in the study. Prevalence of baseline depression symptoms was 29.5% (95%CI 27.9-31.1%), 58.0% (95%CI 54.5-61.4%) and 73.6% (95%CI 70.4-76.8%) in subjects with BADL scores of 0, 1 and ≥2, respectively, and 27.0% (95%CI 25.3-28.7%), 34.2% (95%CI 30.0-38.4%) and 43.8% (95%CI 39.1-48.5%) in subjects without ADL disability while having spouses with BADL scores of 0, 1 and ≥2, respectively. Prospectively, BADL score ≥2 was associated with higher risk of depression symptoms of subjects (OR 1.63, 95% CI 1.03-2.57) and their spouses (OR 1.50, 95% CI 1.01-2.22).

LIMITATIONS

Bias might be introduced because of observational study design, and findings may not be generalizable to younger population.

CONCLUSIONS

ADL disability might have potential to increase risk of depression symptoms of middle-aged and older Chinese adults and their spouses.
