Depression and Associated Factors among Community-Dwelling Thai Older Adults in Northern Thailand: The Relationship between History of Fall and Geriatric Depression

Association of HHV‑6 reactivation and SLC6A3 (C>T, rs40184), BDNF (C>T, rs6265), and JARID2 (G>A, rs9383046) single nucleotide polymorphisms in depression

Major depressive disorder (MDD) is a global health concern with a complex etiology involving genetic, environmental and infectious factors. The exact cause of MDD remains unknown. The present study explored the association between genetic factors, human herpesvirus 6 (HHV-6) and MDD. The present study analyzed single nucleotide polymorphisms (SNPs) and HHV-6 viral load in oral buccal samples from patients with MDD (with and without blood relatives with MDD) and healthy controls. The study used high-resolution melt analysis to examine rs40184 (C>T) in the solute carrier family 6 member 3 (SLC6A31) gene, rs6265 (C>T) in the brain-derived neurotrophic factor (BDNF) gene and rs9383046 (G>A) in the jumonji and AT-rich interaction domain-containing 2 (JARID2) gene. HHV-6 infection and viral load was assessed using the quantitative PCR. Whole-exome sequencing was used to examine SNPs. The variant alleles of SNPs rs40184 [18/40 (45.00) vs. 29/238 (12.55%)] and rs6265 [30/54 (55.46) vs. 117/292 (40.06%)] were significantly more common in patients with MDD than in healthy controls, indicating they may be probable hereditary risk factors for MDD. HHV-6 positivity was significantly more common in carriers of the G/A genotype (12/15, 80%) than carriers of the G/G genotype (75/363, 20.7%) for rs9383046, implying that genetic variations may affect HHV-6 risk and MDD onset. Similarly, HHV-6 viral loads were significantly higher in carriers of the G/A genotype (99,990.85±118,392.64 copies/ng DNA) than carriers of the G/G genotype (48,249.30±101,216.28 copies/ng DNA) for rs9383046. Whole-exome sequencing identified two SNPs in JARID2 (rs11757092 and rs9383050) associated with MDD, highlighting its genetic complexity. The present study helps explain the complex interactions between HHV-6 infection, genetics and MDD onset, improving understanding of how SNPs in JARID2 contribute to HHV-6 infection and MDD onset; these findings may impact future approaches to diagnosing and treating MDD.

Inverted U-shaped relationship between Barthel Index Score and falls in Chinese non-bedridden patients: a cross-sectional study

BACKGROUND

Performing activities of daily living comprise an important risk factor for falls among non-bedridden stroke inpatients in rehabilitation departments.

OBJECTIVES

To explore the correlation between Barthel Index score and the occurrence of falls in non-bedridden stroke rehabilitation inpatients.

METHODS

In this cross-sectional study, information of patients grouped as non-bedridden patients by the Longshi Scale was collected.

RESULTS

A total of 3097 patients were included in this study, with a fall incidence of 10.43%. After adjusting covariates, the total score of Barthel Index and falls in non-bedridden inpatients after stroke presented an inverted U-shaped curve relationship, in which inflection point was 60. The effect sizes on the left and right sides of infection point were 1.02 (95%CI 1.00-1.04) and 0.97 (95%CI 0.96-0.99), respectively.

CONCLUSIONS

Non-bedridden stroke patients with moderate activities of daily living (ADL) capacity may be at particularly increased risk of falls in rehabilitation departments.

Adherence to Mediterranean diet is inversely associated with depressive symptoms in older women: findings from the NutBrain Study

Data on the association of the Mediterranean diet (MD) with depressive symptoms in older people at high risk of depression are scarce. This study aimed to investigate the cross-sectional association of the adherence to the MD and its components with depressive symptoms in an Italian cohort of older men and women. A total of 325 men and 473 women aged 65–97 years (2019–2023) answered a 102-item semi-quantitative FFQ, which was used to calculate the Mediterranean diet score (MDS). Depressive symptoms were assessed using the Centre for Epidemiological Studies Depression Scale; subjects with a score of 16 or more were considered to have depression. Multivariable logistic regression was used for statistical analysis. The occurrence of depressive symptoms was 19·8 % (8·0 % men, 27·9 % women). High adherence to MDS (highest tertile) significantly reduced the odds of having depressive symptoms by 54·6 % (OR 0·454, 95 % CI 0·266, 0·776). In sex-stratified analysis, the reduction was evident in women (OR 0·385, 95 % CI 0·206, 0·719) but not in men (OR 0·828, 95 % CI 0·254, 2·705). Looking at the association of MDS components with depressive symptoms, we found an inverse significant association with fish consumption and the MUFA:SFA ratio above the median only in women (OR 0·444, 95 % CI 0·283, 0·697 and OR 0·579, 95 % CI 0·345, 0·971, respectively). High adherence to the MDS, and a high fish intake and MUFA:SFA ratio were associated with lower depressive symptoms in women only. Future longitudinal studies are needed to confirm these findings and to explore the underlying biological mechanisms.

Prevalence and risk factors of depression and anxiety in primary care

Introduction

Anxiety and depressive disorders are highly prevalent mental health conditions worldwide. However, little is known about their specific prevalence in primary care settings. This study aimed to determine the prevalence of depression and anxiety in the primary care population and identify associated patient characteristics.

Method

We conducted a cross-sectional study using stratified sampling by age with a self-administered questionnaire survey in Singapore's National Health-care Group Polyclinics from December 2021 to April 2022. A total score of Patient Health Questionnaire-9 (PHQ-9) ≥10 represents clinical depression, and a total score of Generalised Anxiety Disorder-7 (GAD-7) ≥10 indicates clinical anxiety. Multivariable logistic regression was used to identify the factors associated with depression and anxiety.

Results

A total of 5694 patients were approached and 3505 consented to the study (response rate=61.6%). There was a higher prevalence of coexisting clinical depression and anxiety (DA) (prevalence=5.4%) compared to clinical depression only (3.3%) and clinical anxiety only (1.9%). The odds of having DA were higher among those aged 21-39 years (odds ratio [OR] 13.49; 95% confidence interval [CI] 5.41-33.64) and 40-64 years (OR 2.28; 95% CI 1.03-5.03) compared to those ≥65 years. Women had higher odds of having DA (OR 2.33; 95% CI 1.54-3.50) compared to men. Respondents with diabetes had higher odds of having DA (OR 1.78; 95% CI 1.07-2.94) compared to those without diabetes.

Conclusion

Coexisting clinical depression and anxiety are significantly present in the primary care setting, especially among younger individuals, patients with diabetes and women. Mental health screening programmes should include screening for both depression and anxiety, and target these at-risk groups.

Promoting the Wellness of Older Adults through Integrated Health-Promoting Programs and Supportive Peers: A Quasi-Experimental Study in Semi-Urban Communities of Northeastern Thailand

INTRODUCTION/OBJECTIVES

Thailand has approached an aged society in which the proportion of older adults rose from 5% in 1995 to 20.7% in 2022 and is projected to increase to 27.2% in 2030. Older adults face health risks and challenges, requiring supportive care. This research aimed to promote the wellness of older adults through Integrated Health-Promoting Programs and Supportive Peers (IHPP-SP) in semi-urban communities.

METHODS

A one-group pretest-posttest quasi-experimental study was conducted among 229 older adults from 22 communities. The interventions covered analyzing community situations and determinants, designing and developing IHPP-SP, enhancing the capabilities of supportive peers, and establishing a support system. Mean and proportion differences were analyzed using the paired t-test and McNemar test.

RESULTS

After implementing IHPP-SP, the mean score significantly increased for happiness (P = .004), Activities of Daily Living: ADLs (P = .034), and family support (P < .001), but did not differ regarding depression (P = .413). The proportion of healthy behaviors significantly increased for tobacco use (P = .035), dietary intake (P = .018), and physical activity (P < .001), but not for alcohol consumption (P = .377).

CONCLUSIONS

The IHPP-SP provided potential benefits to promote the wellness of older adults.

Prevalent falls, fall frequencies and health-related quality of life among community-dwelling older Chinese adults

PURPOSE

Fall is a serious health hazard to older adults. The aim of our study was to investigate the relationship between falls and health-related quality of life (HRQOL) in mainland China.

METHODS

Data from 4579 Chinese community-dwelling older adults was analyzed. Data of falls was self-reported by participants, the HRQOL of older adults was measured by the 3-Level EQ-5D (EQ-5D-3L, 3L). Regression models were built to explore the associations of falls (experience and frequency) with the 3L data (index score, EQ-VAS score and health problems). The potential interaction effects between falls and gender on HRQOL were assessed using a likelihood ratio test, sex-stratified analysis was also performed to separately investigate the associations in men and women.

RESULTS

A total of 368 (8.0%) participants had the experience of fall during the last year. Falls (experience and frequency) were significantly related to EQ-5D-3L index and EQ-VAS scores, fall experience contributed to pain/discomfort and anxiety/depression problems, while fall frequency was associated with physical-related problems and pain/discomfort. Significant interactions between falls and sex in several EQ-5D measures were also observed, and men had lager magnitude of associations than women.

CONCLUSION

Falls were negative associated with overall HRQOL as well as separate HRQOL dimensions among older adults. It also appears that the HRQOL influence on older men is more evident than older women.

Predictors of and healthcare utilisation of depressive symptoms among middle-aged and older adults in Thailand: a national cross-sectional community-based study in 2015

OBJECTIVE

The prevalence of depressive symptoms and healthcare utilisation among the ageing population in Thailand is unclear. The study assessed the predictors of and healthcare utilisation of depressive symptoms among an ageing population in Thailand.

DESIGN

Cross-sectional, population-based study.

SETTING

National sample of people aged 45 years and older in Thailand from the 2015 Health, Ageing and Retirement in Thailand (HART) study.

PARTICIPANTS

The sample included 5135 individuals (≥45 years) with complete depressive symptoms data from the 2015 HART study.

OUTCOME MEASURES

Depressive symptoms were measured with the Centre for Epidemiological Studies Depression Scale. Logistic regression was used to estimate the associations between sociodemographic factors, health factors and depressive symptoms, and the associations between depressive symptoms and different types of healthcare utilisation.

RESULTS

The study population included 5135 participants with a median age of 66 years. The prevalence of depressive symptoms was 13.9%. The proportion of past 2 year hospital admission was 12.8%, hospital outpatient 49.7%, health centre outpatient 26.2%, private clinic 8.4%, traditional medical practitioner 2.8%, medical home visit 4.9% and past-year medical check-up 50.3%. In adjusted logistic regression analysis, low income, residing in the Southern region, history of a cardiovascular disease, brain diseases and/or psychiatric problems and functional disability were positively associated with depressive symptoms. Male sex, being a Buddhist, urban residence, high religious involvement, moderate and high physical activity were negatively associated with depressive symptoms. In fully adjusted logistic regression models, depressive symptoms were positively associated with hospital inpatient utilisation, hospital outpatient utilisation, health centre utilisation and utilisation of a traditional medicine practitioner.

CONCLUSIONS

More than one in 10 participants had depressive symptoms. Chronic conditions, sociodemographic factors, physical inactivity and low religious involvement increased the odds of depressive symptoms. Furthermore, depressive symptoms increased the odds of conventional and traditional healthcare utilisation.

The Association of HHV-6 and the TNF-α (-308G/A) Promotor with Major Depressive Disorder Patients and Healthy Controls in Thailand

Major depressive disorder (MDD) is a silent global health problem that can lead to suicide. MDD development is suggested to result from numerous risk factors, including genetic factors. A precise tool for MDD diagnosis is currently not available. Recently, inflammatory processes have been identified as being strongly involved in MDD development and the reactivation of human herpesvirus type 6 (HHV-6), upregulating cytokines such as TNF-α, which are associated with MDD. Therefore, this study aimed to determine the association of HHV-6 with genetic factors, especially TNF-α mutation, in MDD patients and their relatives compared to healthy controls. The Patient Health Questionnaire (PHQ-9) was used to evaluate MDD status, and 471 oral buccal samples were investigated for HHV-6 infection and viral copy number by qPCR. TNF-α (-308G/A) gene mutation and the cytokines TNF-α, IL-6, and IL-10 were analyzed by high-resolution melting (HRM) analysis and enzyme-linked immunosorbent assay (ELISA). Whole-exome sequencing of buccal samples was performed to analyze for genetic factors. The results showed significantly higher HHV-6 positivities and viral loads in MDD patients (15/59 (25.67%) and 14,473 ± 16,948 copies/µL DNA) and their relatives (blood relatives 17/36 (47.22%) and 8146 ± 5656 copies/µL DNA); non-blood relatives 7/16 (43.75%) and 20,721 ± 12,458 copies/µL DNA) compared to the healthy population (51/360 (14.17%) and 6303 ± 5791 copies/µL DNA). The TNF-α (-308G/A) mutation showed no significant difference. Surprisingly, 12/26 (46.15%) participants with the TNF-α (-308G/A) mutation showed HHV-6 positivities at higher rates than those with wild-type TNF-α (-308G) (70/267 (26.22%)). HHV-6-positive participants with TNF-α (-308G/A) showed higher levels of TNF-α, IL-6, and IL-10 than those of negative control. Exome analysis revealed that common mutations in immune genes were associated with depression. Therefore, this study unveiled the novel association of inflammatory gene TNF-α (-308G/A) mutations with HHV-6 reactivation, which could represent a combined risk factor for MDD. This result could induce further research on MDD development and clinical applications.

Evaluation of a depression care model for the hill tribes: a family and community-based participatory research

BACKGROUND

Even though, there is a particularly high prevalence of depression among individuals from the hill tribes in northern Thailand, they are unable to receive appropriate intervention due to cultural, transportation, communication, and legal barriers. Using community-based participatory research (CBPR), a depression care model was developed for the hill tribe population. The effectiveness of this model was examined using questionnaires, observations, focus groups, and in-depth interviews.

METHODS

Participants include people with depression (n = 17) who were chosen based on their mild to moderately severe depression scores on the Patient Health Questionnaire 9-item (PHQ-9 scores of 5-19) and their caregivers (n = 5). The in-depth interview was conducted to distinguish the selected participants into two groups. The first group, the self-help group program, consisted of 12 participants endorsing negative thoughts about themselves and inappropriate problems solving. The second group, the family camp program, had ten participants, including five patients with family-related issues and their family members. Subjects separately participated in either the self-help or the family groups over three weeks. They completed the PHQ-9 at the beginning and end of the intervention. Questionnaires, observations, focus groups, and in-depth interviews were used to evaluate the effectiveness of the model. Content analysis was used to examine the qualitative data. Wilcoxon signed-rank test was used to analyze the changes in the severity of depression before and after participation in the intervention.

RESULTS

The depression scores on the PHQ-9 of 12 participants improved significantly (11.92 ± 1.08 vs. 3.08 ± 0.51; p = 0.002) following participation in the self-help group. Increased self-esteem and improved interpersonal relationships were reported by participants in the self-help group program during interviews. There was no significant difference in the depression scores of 10 participating in the family camp program (6.00 ± 3.83 to 5.30 ± 3.56; p = 0.161).

CONCLUSION

A model for depression care was tested in a hill tribe community, and its effectiveness was clearly observed. The developed model can be applied to other hill tribe communities in northern Thailand to improve depression care.

Predictors of depression among the elderly persons with disabilities in Indonesia

BACKGROUND

Depression is a major mental problem in the elderly, particularly those with disability. This study's aim was to identify variables that predict depression in the elderly with disabilities.

MATERIALS AND METHODS

This cross-sectional study was conducted in Gunungkidul Regency and Yogyakarta City from April to June 2021. The study participants were community-dwelling elderly aged 60 years and above with disabilities, who could communicate verbally without any apparent cognitive impairment. Data was collected by interviewing participants using structured questionnaire on following sections: Demographic characteristics, Mini-Mental State Examination (MMSE), Washington Group Short Set (WG-SS), Barthel Index of activities of daily living (ADL), Lawton Instrumental ADL (IADL) Scale, and Geriatric Depression Scale-30 (GDS-30). Multivariate linear regression analysis applied to identify variables significantly correlated with depression. Multinomial logistic regression analysis performed to obtain the odds ratio (OR).

RESULTS

Study included 115 elderly persons with disabilities. Most of them had mobility impairment. Higher independence in ADL and being married were related with lower risk of depression, whereas increased age at disability increased the risk of depression (P = 0.001). The elderly who had greater independence with daily activities were less likely to have depression (OR = 0.639 for mild depression and OR = 0.589 for severe depression). Those who were not married were more likely to have mild depression (OR = 3.203) and severe depression (OR = 29.119). compared to the married elderly. Age at acquiring disability was associated with higher risk for mild depression (OR = 1.025) and severe depression (OR = 1.053). Higher independence in ADL and being married were related with lower risk of depression, whereas increased age at disability increased the risk of depression (P = 0.001).

CONCLUSION

Independence in the ADL, being married, and being disabled as a young adult are negative predictors of depression in the elderly with disability.

Home-Based Exergame Program to Improve Physical Function, Fall Efficacy, Depression and Quality of Life in Community-Dwelling Older Adults: A Randomized Controlled Trial

This study aimed to investigate the effects of home-based exergame programs on physical function, fall efficacy, depression, and health-related quality of life in community-dwelling older adults. Fifty-seven participants aged 75 years or older were divided into control and experimental groups. The experimental group received a home-based exergame program that included balance and lower-extremity muscle strength for 8 weeks. The participants exercised at home for 50 min three times a week and were monitored through a video-conference application. Both groups received online education on musculoskeletal health once a week, whereas the control group did not exercise. Physical function was assessed using the one-leg standing test (OLST), Berg balance scale (BBS), functional reaching test (FRT), timed up-and-go test (TUGT), and five-times sit-to-stand (FTSTS). Fall efficacy was assessed using the modified falls efficacy scale (MFES). Depression was assessed using the geriatric depression scale (GDS). Health-related quality of life was assessed using a 36-item short-form health survey (SF-36). The experimental group showed an overall improvement in OLST, BBS, FRT, TUGT, and FTSTS (p < 0.05). MFES was significantly increased in the experimental group after the intervention (p < 0.05). The GDS significantly decreased in the experimental group after the intervention (p < 0.05). In SF-36, role limitations due to physical health, general health, and fatigue (energy and fatigue) items improved in the experimental group after intervention (p < 0.05). An 8-week home-based exergame program improved physical function, fall efficacy, depression, and health-related quality of life in older adults. The study was registered on ClinicalTrials.gov (NCT05802537).

Determinants of Health-Related Quality of Life Among Community-Dwelling Thai Older Adults in Chiang Mai, Northern Thailand

Background

Population aging has been growing worldwide and Thailand has become an aged society with 20% of its population aged 60 and over. Age-related decline in physical and mental health impacts the health-related quality of life (HRQOL) of older adults.

Purpose

We aimed to describe the HRQOL of Thai older adults, residing in the community.

Methods

This cross-sectional survey was part of a Community-Integrated Intermediary Care project (CIIC), TCTR20190412004. A total of 1509 participants from an intervention arm of a cluster randomized controlled trial were included. A Thai version of the Euro-Qol questionnaire (EQ-5D-5L) was used to determine the HRQOL and associated sociodemographic background, health behaviors and underlying diseases of a representative sample from Maehia, Chiang Mai, Thailand. SPSS version 24 was used to analyze data via descriptive analysis and binary logistic regression.

Results

The mean age of the participants was 69.31±7.10 years, and nearly a quarter (23.8%) was older than 75 years. The mean EQ index score was 0.81±0.23 and older age, lower educational attainment, unemployment, lack of exercise habits, current smokers, having history of a fall in the last 6 months, diabetes, hyperlipidemia, dependency assessed using Barthel's Activity of Daily Living (ADL) Index, and depression using the Geriatric Depression Scale (GDS) were more likely to represent HRQOL-related problems.

Conclusion

Our findings have highlighted the factors affecting the HRQOL of community-dwelling older adults which could be of importance in preparing for active and healthy aging communities. The routine dependency assessment using the ADL index will be useful in estimating the HRQOL of the aging population. Fall prevention programs are also recommended to reduce dependency. Moreover, the association of having diabetes and hyperlipidemia with problems in HRQOL dimensions highlight the need for public health intervention not only to prevent the increasing burden of non-communicable diseases but also to improve the HRQOL of older adults.
