The longitudinal association between depressive symptoms and functional abilities in older patients

Association between hygiene environment, care needs, and depression among Chinese older adults: A cohort analysis from the CHARLS

Limited research has explored the link between functional dependency, care needs, and depression among older adults. This study aims to explore the association between dependency levels and depression among Chinese older adults, as well as examine the relationship between hygiene environment and these two factors. Data were obtained from the CHARLS 2011-2018. A total of 4871 individuals aged 60 years and older were included. Generalized estimating equations were employed for the analysis. A conceptual framework was established to longitudinally illustrate the pathway from hygiene environment to dependency levels to depression. Findings indicated higher dependency levels and poorer hygiene environments were associated with an increased risk of depression, with dependency serving as a mediator between hygiene environment and depression. Policymakers should prioritize improvements in rural sanitation and long-term care policies, healthcare providers should enhance depression screening and caregiver training, and clinicians should provide personalized interventions to better address mental health challenges.

Latent Trajectories of Activities of Daily Living Disability and Associated Factors Among Adults with Post-Intensive Care Syndrome One Week After ICU Discharge

Objective

To identify the latent trajectories of activities of daily living (ADL) disability and the influential factors among adults with post-intensive care syndrome (PICS).

Methods

We evaluated five-time longitudinal data about PICS diagnosed in 434 of 593 assessed patients (73.19%). Disability was measured by the Barthel index scale, which grades individuals according to how difficult it is to carry out ADL. We utilized the growth mixture model (GMM) to identify latent trajectories and associated factors.

Results

Two groups with distinct trajectories of ADL disability were identified, including the Severe Disability Sustained Group and the Disability Recovery Group. People who were of advanced age transferred to another hospital for treatment, or had cognitive impairment or depression were more likely to be classified into the Severe Disability Sustained Group (P < 005).

Conclusion

There are two potential trajectories of ADL disability in patients with PICS, which are the severe disability persistence group and the disability recovery group. Improvement in cognitive impairment or depression may contribute to recovery from disability, transfer to hospital or advanced age may not be conducive to recovery of ADL ability, and disability may last longer.

Bidirectional, longitudinal associations between depressive symptoms and IADL/ADL disability in older adults in China: a national cohort study

INTRODUCTION

Based on the data from the China Health and Retirement longitudinal study (CHARLS), we aimed to investigate the bidirectional relationship between depressive symptoms and functional disability.

METHODS

Data were collected across 3 waves from 2013 to 2018. The activities of daily living (ADLs) and the instrumental activities of daily living (IADLs) scales were used to measure functional disability and the CESD-10 was used to measure depressive symptoms. Cross-lagged models were performed to examine cross effect between depressive symptoms and functional disability across three waves.

RESULTS

Data on 10,092(mean [SD] age, 61.98[8.44] years; 3764 females [37.30%]) and 10,180 participants (mean [SD] age, 62.01[8.46] years; 3788 females [37.21%]) in IADL sample and ADL sample were included in the analyses. For IADL disability, the cross-lagged model shows a bidirectional association across three waves; the multivariable GEE model revealed that changes in CESD-10 score across waves were associated with worse IADL disability (β ranges: 0.08-0.10) and vice versa, worsen of IADL disability ascending developing of CESD-10 score (β ranges: 0.09-0.10). For ADL disability, the cross-lagged model shows a bidirectional association across three waves; the multivariable GEE model revealed that changes of CESD-10 score across waves were associated with worse IADL disability (β ranges: 0.08-0.10) and vice versa, worsen of IADL disability ascending developing of CESD-10 score (β ranges: 0.09-0.10).

DISCUSSION

Study findings underscore a significant bidirectional between depressive symptoms and functional disability in older adults. Thus, simultaneous intervention should be taken to manage the mutual development of functional disability and depression.

Family Support During Hospitalization Buffers Depressive Symptoms Among Independent Older Adults

OBJECTIVES

Hospitalization is a stressful event that may lead to deterioration in older adults' mental health. Drawing on the stress-buffering hypothesis, we examined whether family support during hospitalization would moderate the relations between level of independence and in-hospital depressive symptoms.

METHOD

This research was a secondary analysis of a cohort study conducted with a sample of 370 hospitalized older adults. Acutely ill older adults reported their level of independence at time of hospitalization and their level of depressive symptoms three days into the hospital stay. Family support was estimated by a daily report of hours family members stayed with the hospitalized older adult.

RESULTS

Independent older adults whose family members stayed longer hours in the hospital had fewer depressive symptoms than independent older adults with shorter family visits. Relations between depressive symptoms and family support were not apparent for dependent older adults, even though their family members stayed more hours.

CONCLUSIONS

This study partially supports the stress-buffering hypothesis, in that social support ameliorated depressive symptoms among hospitalized independent older adults.

CLINICAL IMPLICATIONS

Assessing depressive symptoms and functional ability and creating an environment conducive to family support for older adults may be beneficial to hospitalized older adults' mental health.

Decision tree distinguish affective disorder diagnosis from psychotic disorder diagnosis with clinical and lab factors

Background

Affective symptoms usually occur at the same time of psychotic symptoms. An effective predictive method would help the differential diagnosis at an early stage of the mental disorder. The purpose of the study was to establish a predictive model by using laboratory indexes and clinical factors to improve the diagnostic accuracy.

Methods

Subjects were patients diagnosed with psychiatric disorders with affective and/or psychotic symptoms. Two patient samples were collected in the study (n = 309) With three classification methods (logistic regression, decision tree, and discriminant analysis), we established the models and verified the models.

Results

Seven predictors were found to be significant to distinguish the affective disorder diagnosis from the psychotic disorder diagnosis in all three methods, the 7 factors were Activities of daily living, direct bilirubin, apolipoproteinA1, lactic dehydrogenase, creatinine, monocyte count and interleukin-8. The decision tree outperformed the other 2 methods in area under the receiver operating characteristic curve, and also had the highest percentage of correctly classification.

Conclusion

We established a predictive model that included activities of daily living, biochemical, and immune indicators. In addition, the model established by the decision tree method had the highest predictive power, which provided a reliable basis for future clinical work. Our work would help make diagnosis more accurate at an early stage of the disorder.
