Mediating Effect of Cognitive Social Capital on the Relationship Between Physical Disability and Depression in Elderly People of Rural Pakistan

Inverse Association Between Mothers' Cognitive Social Capital During Pregnancy and Postpartum Depression: The Japan Environment and Children's Study

Purpose

Several studies have reported an apparent inverse association between cognitive social capital and depression in various groups, but insights into this association in perinatal mothers are fairly limited. Therefore, we explored the possible associations between expectant mothers' cognitive social capital (ie, neighborhood trust and reciprocity and generalized trust and reciprocity) and postpartum depression at 1 and 6 months after delivery.

Patients and Methods

As part of an ongoing cohort study, the Japan Environment and Children's Study, cognitive social capital was evaluated using a questionnaire survey during mid-late pregnancy and postpartum depression was assessed using the Japanese version of the Edinburgh Postnatal Depression Scale. This study analyzed data from 81,670 mothers. Logistic regression analysis was performed to calculate the odds ratios (ORs) for postpartum depression by the degree of neighborhood and generalized trust and reciprocity (high, relatively high, neutral, relatively low, and low) using the high category as a reference.

Results

Regardless of the measurement time point, prevalence gradually increased as the degree of neighborhood trust decreased (all p < 0.001), suggesting a higher likelihood of postpartum depression with less neighborhood trust. A comparable tendency was also observed for the other three variables of cognitive social capital (all p < 0.001). Moreover, the inverse association of postpartum depression with generalized trust and reciprocity was markedly stronger (ORs for low category ≥ 2.70) than that with neighborhood trust and reciprocity (ORs for low category ≤ 1.96).

Conclusion

Our findings highlight a statistically significant inverse association between cognitive social capital during pregnancy and postpartum depression at both time points.

Depression in persons with disabilities: a scoping review

Individuals with disabilities are more vulnerable to depression development than the general population. This study sought to map the evidence on current knowledge of depression, intervention strategies, and assessment tools among people with disabilities. This review was conducted following Arksey and O'Malley's scoping review methodology framework. An electronic search was performed on four English databases: PubMed, Cochrane Library, PsycINFO, and Web of Science. The original search returned 1802 results, with 1,116 from Web of Science, 626 from PubMed, 25 from Cochrane, and 35 from PsycINFO. After removing duplicates, 786 articles were chosen for the title and abstract screening processes. Finally, 112 full-text publications were deemed eligible, with 41 papers being included in this scoping review for analysis. A large proportion (32; 78.04%) of the studies chosen were cross-sectional, 14 (34.14%) of them reported general disability, 12 (29.26%) used a patient health questionnaire (PHQ-9) to measure depression, and 14 (34.14%) had interventions, including cognitive behavioral therapy, psychological counseling, social support, and physical activity. All interventions successfully reduced the severity of the depression. Cognitive behavioral therapies and psychological counseling were widely used interventions that had a significant impact on reducing depression. More randomized controlled trials are required, and they should focus on individuals with specific disabilities to provide disability-specific care that can improve the quality of life for disabled individuals.

Nationwide trends in the prevalence and incidence of depressive disorders and their correlates among adults with disabilities in Korea from 2006 to 2017

BACKGROUND

Evidence suggests that people with disabilities are more likely to suffer from depression. Previous studies have focused on depressive disorders in specific disability types or age groups using small-scale cross-sectional samples. We investigated longitudinal trends in the prevalence and incidence of depressive disorders according to disability types and severity levels in the entire Korean adult population.

METHODS

The age-standardised prevalence and incidence of depressive disorders were investigated using National Health Insurance claims data from 2006 to 2017. The odds of depressive disorders by type and severity were examined using logistic regression after adjusting for sociodemographic characteristics and comorbidities based on merged 2006 to 2017 data.

RESULTS

Both the incidence and prevalence of depressive disorders were higher among the disabled than the non-disabled, with the prevalence gap being larger than the incidence gap. In regression analyses, adjusting for sociodemographic characteristics and comorbidities considerably reduced the odds ratios, particularly for incidence. The severity of disabilities was inversely associated with the incidence of depressive disorders. Brain injury and disabilities in major internal organs were associated with lower odds of developing depressive disorders than in non-disabled individuals.

CONCLUSIONS

A significant proportion of depressive disorders in disabled individuals are caused by financial hardships or comorbidities rather than disabilities themselves. We must pay special attention to those who cannot access healthcare services due to severe disabilities and those whose depressive disorders are misdiagnosed as intellectual disabilities. More research is required to elucidate the causal mechanisms underlying depressive disorders in people with various types and severities of disabilities.

Dyadic transmission of depression in the elderly people with disabilities to caregiver burden: Multiple mediating roles of caring ability and resilience

OBJECTIVES

The interaction between elderly people with disabilities and their caregivers and the improvement of caregiver burden is important for elderly people with disabilities and their caregivers. This study aims to explore the multiple mediating roles of caregiver's caring ability and resilience in depression in the elderly people with disabilities on caregiver burden.

METHODS

A total of 246 elderly people with disabilities at home and their family caregivers from 5 regions were investigated by questionnaires, including the General Information Questionnaire, the Patient Health Questionnaire, the Family Caregiver Task Inventory, the Resilience Scale, and the Caregiver Burden Interview. A multiple mediation model was constructed and tested.

RESULTS

Univariate analysis showed that the caregiver burden of disabled elderly men is higher than that of women; the lower the level of self-care of disabled elderly individuals, the greater the burden on their caregivers (both P<0.05). Correlation analysis showed that depression of the disabled elderly people was positively correlated with the caregiver burden (P<0.01). Caregiver's caring ability was positively correlated with caregiver's resilience (P<0.01), and both were negatively correlated with caregiver burden (both P<0.01). The multiple mediating effects of caregiver caring capacity and resilience between depression of the disabled elderly people and caregiver burden were significant, with the mediating effects of caregiver caring capacity and resilience accounting for 68.9% and 26.2% of the total effect, respectively.

CONCLUSIONS

Depression in the elderly people with disabilities can indirectly affect caregiver burden through the caregiver's caring ability and resilience. Families of older people with disabilities need to focus on both the elderly and their caregivers. It is possible to reduce the caregiver burden and improve the physical and mental health of the dyads by empowering the caregiver's caring ability and resilience.

Linking chronic diseases, cognitive impairment and depressive symptoms in Chinese older adults: A three-wave population-based longitudinal study

OBJECTIVE

Despite previous studies illustrate that chronic diseases are risk factors for older adults' psychological health, little is known about its mediating mechanism. This study aims to examine the mediating effect of cognitive impairment. Also, a particular emphasis is placed on whether the Hukou system in China contributes to the adverse effect of chronic diseases on depressive symptoms.

METHODS

Using the 2014, 2016 and 2018 rounds of the China Longitudinal Aging Social Survey (CLASS), this study estimates fixed-effect panel models for the effect of chronic diseases on depressive symptoms and the mediating effect of cognitive impairment. Meanwhile, the interaction effect of chronic diseases and hukou status on depressive symptoms is also examined.

RESULTS

The significant relationship between chronic diseases and depressive symptoms is supported in Chinese older adults and this association is found to be mediated by cognitive impairment. Moreover, no urban-rural disparities exist in the effect of chronic diseases on depressive symptoms.

LIMITATION

All of the measures in this study are relied on self-report, which may result in reporting biases.

CONCLUSION

This study contributes to our understanding of the relationship between chronic diseases and depressive symptoms and extends the previous literature by considering the Hukou status, a highly distinctive Chinese variable. Practical implications for policy development and intervention design are also provided.

Associations Between Consumption of Different Vegetable Types and Depressive Symptoms in Japanese Workers: A Cross-Sectional Study

Purpose

Vegetable intake is an important part of our everyday diet and is associated with many positive health outcomes. Although previous studies have investigated the association between vegetable consumption and depressive symptoms among various populations, no study has examined this association in the adult working population. The present study investigated whether the frequency of consumption of a specific type of vegetable is associated with the prevalence of depressive symptoms in Japanese adult workers.

Participants and Methods

The final participants consisted of 1724 Japanese adults, and a cross-sectional study was conducted to analyze the results. The frequency of vegetable consumption and depressive symptoms was evaluated using a brief-type self-administered diet history questionnaire and the Zung Self-Rating Depression Scale (SDS), respectively. The association between the variables was examined using Poisson regression analysis. Age-stratified analysis was performed, and SDS cut-off values of 45 and 50 were used to perform a sensitivity analysis.

Results

After adjustment for covariates, including age, body mass index, sociodemographic and lifestyle-related variables, health condition, C-reactive protein, and other dietary variables, an inverse association was found between tomato product consumption and the prevalence of depressive symptoms among men (P for trend <0.01); however, no significant association was found for other vegetable types. For women, there was no association between the frequency of consumption of any of the vegetable types and the prevalence of depressive symptoms. The results were confirmed by the age-stratified analysis for both genders.

Conclusion

Consumption of tomato products may help alleviate depressive symptoms, regardless of differences in dietary culture among men.

Investigating the effect of social support, social capital, and coping on the positive state of mind of Iranian older people with human immunodeficiency virus/acquired immunodeficiency syndrome

BACKGROUND

Social resources help to adapt to stress and might positively affect the well-being of individuals with severe conditions like human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). The present study investigates the effect of social support, social capital, and coping in a positive state of mind of Iranian older people with HIV/AIDS.

MATERIALS AND METHODS

This cross-sectional study was conducted on 160 older people with HIV referred to AIDS clinics in Tehran in 2019. Samples were randomly selected from patients aged 50 years and older. Data were collected using a questionnaire, a positive state of mind, social capital, coping, social support, and a checklist of demographical variables. Data analysis was performed using SPSS software version 21.

RESULTS

A significant positive correlation was found between social support, social capital, coping, education, and a positive state of mind. A significant negative correlation was also found between age, several chronic diseases of the patient, and a positive state of mind. The linear regression results showed that social support, social capital, coping, and education improved the positive state of mind.

CONCLUSIONS

Based on our findings, we believe that social and psychological interventions effectively enhance patients' positive state of mind with HIV and ultimately, improve their quality of life.

Chronic Diseases and Associated Factors among Older Adults in Loja, Ecuador

(1) Background: This study aimed to explore the symptoms, functional status, and depression in patients with chronic diseases in Loja, Ecuador. (2) Methods: A cross-sectional study was carried out with patients over 60 years old having at least one chronic disease and cared for in healthcare centers of the Health Ministry of Ecuador or living in associated geriatric centers. (3) Results: The sample comprised 283 patients with a mean age of 76.56 (SD 7.76) years. The most prevalent chronic diseases were chronic obstructive pulmonary disease, followed by arterial hypertension and diabetes. Patients with a joint disease had the worst scores for the majority of the symptoms assessed with the Edmonton Scale. Cancer, dementia, and arterial hypertension contributed the most to the dependence levels assessed with the Barthel Index. Dementia contributed the most to the poor performance status evaluated with the Karnofsky Performance Status. Cancer and diabetes contributed the most to depression. Patients with a higher number of chronic diseases reported worse functional status. (4) Conclusions: Targeted interventions to address symptoms, functional status, and depression in patients with chronic diseases are needed.

Role of Perceived Social Support on the Association between Physical Disability and Symptoms of Depression in Senior Citizens of Pakistan

An emerging body of literature has implied that perceived social support is known as an upstream element of cognitive health. Various dimensions of perceived social support may have divergent influence on physical and cognitive health in later life. The present study aimed to investigate the mediating role of perceived social support on the relationship between physical disability and symptoms of depression in senior citizens of Pakistan. The data were collected from three metropolitan cities (Lahore, Faisalabad, Multan) in the Punjab province of Pakistan and 100 participants were approached from each city with a total sample size of 300. The results demonstrated that family support, friends' support, and significant others' support mediated the association between physical disability and symptoms of depression, with an indirect effect of 0.024, 0.058, and 0.034, respectively. The total direct and indirect effect was 0.493. Physical disability was directly associated with symptoms of depression and greater physical disability predicted a higher level of symptoms of depression. Perceived social support, including family support, friends' support, and significant others' support, showed an indirect association with symptoms of depression. Furthermore, family support and friends' support were more significantly associated with symptoms of depression as compared to significant others' support. The research discoveries have better implications for health care professionals, hospice care workers, and policy makers. A holistic approach is required to prevent senior citizens from late-life mental disorders.
