Association between religious practice and risk of depression in older people in the subacute setting

Religiosity/Spirituality and Mental Health in Older Adults: A Systematic Review and Meta-Analysis of Observational Studies

Objectives

The present study investigated the association between religious and spiritual (RS) practices with the prevalence, severity, and incidence of mental health problems in older adults.

Methods

We conducted a systematic review and meta-analysis of cross-sectional and longitudinal studies that investigated older adults aged 60+ years and assessed RS using valid scales and questions from valid scales, and mental health according to validated multidimensional or specific instruments. Studies were retrieved from MEDLINE, LILACS, SCOPUS, CINAHL, and AgeLine databases until July 31, 2021. The risk of bias was evaluated using the Newcastle-Ottawa Quality Assessment Scale (NOS). A pooled effect size was calculated based on the log odds ratio (OR) and Z-scores. This study is registered on PROSPERO.

Results

One hundred and two studies that investigated 79.918 community-dwellers, hospitalized, and institutionalized older adults were included. Results indicated that high RS was negatively associated with anxiety and depressive symptoms, while a positive association was observed with life satisfaction, meaning in life, social relations, and psychological well-being. Specifically, people with high spirituality, intrinsic religiosity, and religious affiliation had a lower prevalence of depressive symptoms. In relation to longitudinal analysis, most studies supported that high RS levels were associated with a lower incidence of depressive symptoms and fear of death, as well as better mental health status.

Conclusion

Findings of the present study suggest that RS are significantly associated with mental health in older adults. People with high RS levels had a lower prevalence of anxiety and depressive symptoms, as well as reported greater life satisfaction and psychological well-being, better social relations, and more definite meaning in life. Data provided by an increasing number of longitudinal studies have supported most of these findings.

Biological, Psychological, and Social Determinants of Depression: A Review of Recent Literature

Depression is one of the leading causes of disability, and, if left unmanaged, it can increase the risk for suicide. The evidence base on the determinants of depression is fragmented, which makes the interpretation of the results across studies difficult. The objective of this study is to conduct a thorough synthesis of the literature assessing the biological, psychological, and social determinants of depression in order to piece together the puzzle of the key factors that are related to this condition. Titles and abstracts published between 2017 and 2020 were identified in PubMed, as well as Medline, Scopus, and PsycInfo. Key words relating to biological, social, and psychological determinants as well as depression were applied to the databases, and the screening and data charting of the documents took place. We included 470 documents in this literature review. The findings showed that there are a plethora of risk and protective factors (relating to biological, psychological, and social determinants) that are related to depression; these determinants are interlinked and influence depression outcomes through a web of causation. In this paper, we describe and present the vast, fragmented, and complex literature related to this topic. This review may be used to guide practice, public health efforts, policy, and research related to mental health and, specifically, depression.

The Relationship Between Four Measures of Religiosity and Cross-National Variations in the Burden of Dementia

Background

Several researchers have identified a possible protective effect of religiosity on the risk of dementia. Specific aspects of religiosity may be associated with this attenuation of risk, and it may be partially mediated through an effect on depressive symptoms or social support. However, this effect has only been demonstrated in selected cohorts to date.

Methods

This study was based on a cross-national analysis of associations. Correlations between World Health Organization estimates of the burden of dementia and four survey-derived measures of religiosity were examined across 101 countries, while controlling for estimates of late-life depression and social capital.

Results

Specific aspects of religiosity, such as attendance at religious services (Pearson’s r= -0.57), daily prayer (r = -0.58), and perception of religion as very important (r = -0.65), were associated with lower national levels of Alzheimer’s and other dementias (p< 0.01 for all correlations). This effect was partially mediated through an inverse relationship between religiosity and depression, but remained significant even after controlling for it and on multivariate analyses (β = -0.38 to -0.57, p< 0.01 for all measures). There was no evidence for a mediating effect of social capital.

Conclusions

Specific religious beliefs and practices may have a protective effect on dementia risk at the population level. These may involve group effects that require further study, such as reductions in depression in the elderly, or may involve beneficial effects on the stress response and cellular ageing in vulnerable individuals; however, the latter cannot be inferred with certainty from a group-level analysis. These results are consistent with earlier research and suggest a potential role for religious-based preventive strategies at the population level.

Geriatric Oncology, Spirituality, and Palliative Care

Cancer is a major cause of morbidity and mortality for older individuals. Palliative care is essential to improve the outcome of cancer treatment in terms of quality of life and treatment satisfaction. This review examines the influence of spirituality on aging in general and on the management of older cancer patients. A spiritual perspective has been associated with successful aging, and with better tolerance of physical and emotional stress, including the ability to cope with serious diseases and with isolation. It has also been associated with decreased risk of suicide and depression. Gerotranscendence, the more urgent search for meaning by older than younger individuals, confirms the importance of spirituality in this phase of life. Spirituality has also improved the quality of life and reduced the risk of disease and death for the patient's caregiver. Addressing patient and caregiver spirituality may render the palliative care of cancer more effective and may also aid in detection and management of spiritual pain, which may prevent healing at the end of life.

Confirming the Tripartite Structure of the Duke University Religion Index: A Methodological Approach

The present study provided a methodological critique regarding psychometric investigations of the Duke University Religion Index (DUREL) and its variants. Nine hundred seventeen (630 females and 287 males) university students (M age = 19.24) completed the DUREL, the Personal Religious Inventory, and the Daily Spiritual Experiences Scale online. Confirmatory factor analyses were performed to assess a three-factor (organizational religious activity; non-organizational religious activity; and intrinsic religiosity) and a unidimensional model of the DUREL. Chi-square difference tests were performed, and Akaike information criterion values and Bayesian information criterion values were compared between the models, each of which supported the three-factor model for the DUREL over the unidimensional model. Convergent validity for the three factors of the DUREL emerged through Spearman's rho correlations with measures of personal prayer, ritual religious attendance, religious integration, Closeness to the Divine. This study concluded that the DUREL is a multidimensional measurement of religion for use in English-speaking university students, and it provided a broad methodological note regarding future investigations of measures of religion or spirituality that possess an existing theoretical model.
