Walking Interventions and Sleep Quality of Persons Living With Dementia and Their Family Caregivers: Effects of Different Walking Companions.

PURPOSE: To examine the effect of walking interventions on sleep quality of persons with dementia (PWD) and their caregivers (dyads), and how different companions affect results. METHOD: Forty-five dyads were divided into three groups: a control group and two experimental groups (one with a care attendant, one with a family caregiver). The two experimental groups engaged in 120 minutes of walking per week for 24 weeks. RESULTS: A significant improvement in sleep quality was observed among PWD in the family caregiver group (Wald χ2 = 4.55, p = 0.033), whereas there was no improvement in the care attendant group. A slight improvement in sleep quality of family caregivers was also found. CONCLUSION: Findings suggest the importance of creating individualized walking activity plans for dyads, incorporating trust and rapport-building strategies to improve sleep quality.

The Experiences of Migrant Care Workers in Long-term Care Facilities: A Scoping Review.

The employment of migrant care workers provides a remedy to face the challenges of increased demand for care of older adults. A scoping review aimed to identify, categorize, and summarize the existing knowledge about migrant care workers' working experiences in long-term care facilities. Identifying gaps in the literature can inform future research. Five electronic databases were searched in April 2024 in addition to a manual search for articles published in English. Forty-five articles were reviewed. A few studies described migrant care assistants' main tasks as assisting physical care and care assistants' characteristics grouped into personal and acquired qualities to provide good quality care. Migrant care workers experienced work satisfaction, achievement, adaptability and adjustment, organizational support, work burden, sense of loneliness, low wages, low social status, and loss of profession. They faced challenges involving inadequate knowledge of palliative care, communication and language barriers, cultural and religious differences, and health concerns. Friendly and discriminatory relationships were found between migrant care workers and stakeholders. Existing evidence regarding the experiences of migrant care workers in delivering palliative care to dying residents or facilitating death preparation is limited. Additionally, there is a notable absence of data from the perspectives of employers and residents on discrimination issues. Further research is necessary to investigate these areas.

Development and psychometric properties of a friendly dietary function assessment scale for home-dwelling people with dementia.

BACKGROUND: Mealtime difficulties related to cognitive functioning negatively impact a patient's life during the various stages of dementia, and they typically cause a burden and stress on family caregivers. Most people with dementia live at home alone or are cared for by informal caregivers, typically their spouses or other family members. However, no suitable screening tools for home-dwelling patients with dementia have been developed, nor have measurements focused on executive and self-eating functions. This study aimed to develop and evaluate the psychometric properties of the Dietary Function Assessment Scale (DFAS) for community-dwelling persons with dementia. METHODS: A mixed-method design was used to develop the instrument. Methods included a comprehensive literature review to identify the item pool and an expert panel to assess the initial item pool. We performed convenience sampling of 190 home-dwelling people with dementia for psychometrical evaluation. The psychometric properties tests included item and factor analyses, criterion-related validity testing, internal consistency reliability testing, and defining the optimal cut-off values. The study was conducted from 2018 to 2019. RESULTS: Items were generated based on an extensive literature review and pre-existing scales related to mealtime and executive functions in persons with dementia. The S-CVI/Ave of the DFAS was 0.89. A Principal Component factor analysis demonstrated seven items, with a two-factor structure accounting for 56.94% of the total variance. The two extracted factors were Self-eating ability and Dietary executive function. The confirmatory factor analysis indicated a good model fit. The criterion-related validity was adequate (r = -0.528, p < 0.01). The reliability of Cronbach's alpha internal consistency was 0.74, and McDonald's Omega coefficient was 0.80; the optimal cut-off value of 13 points with an AUC of 0.74 was established to determine poor dietary functioning in persons with dementia. CONCLUSION: The DFAS was simple, user-friendly, and a valid and reliable instrument to assess dietary functioning in community-dwelling persons with dementia. This short scale can be helpful for caretakers, who can use it to identify the dietary needs of home-dwelling persons with dementia and improve their care and eating experience.

Cognitive Decline Related to Diet Pattern and Nutritional Adequacy in Alzheimer's Disease Using Surface-Based Morphometry.

Dietary pattern (DP) results in nutrition adequacy and may influence cognitive decline and cortical atrophy in Alzheimer's disease (AD). The study explored DP in 248 patients with AD. Two neurobehavioral assessments (intervals 13.4 months) and two cortical thickness measurements derived from magnetic resonance images (intervals 26.5 months) were collected as outcome measures. Reduced rank regression was used to assess the groups of DPs and a linear mixed-effect model to explore the cortical neurodegenerative patterns. At screening, underweight body mass index (BMI) was related to significant higher lipid profile, impaired cognitive function, smaller cortical thickness, lower protein DP factor loading scores and the non-spouse caregiver status. Higher mini-mental state examination (MMSE) scores were related to the DP of coffee/tea, compared to the lipid/sugar or protein DP group. The underweighted-BMI group had faster cortical thickness atrophy in the pregenual and lateral temporal cortex, while the correlations between cortical thickness degeneration and high HbA1C or low B12 and folate levels were localized in the medial and lateral prefrontal cortex. The predictive model suggested that factors related to MMSE score were related to the caregiver status. In conclusion, normal or overweight BMI, coffee/tea DP group and living with a spouse were considered as protective factors for better cognitive outcomes in patients with AD. The influence of glucose, B12 and folate on the cortical degeneration was spatially distinct from the pattern of AD degeneration.

Adequacy of nutrition and body weight in patients with early stage dementia: The cognition and aging study.

BACKGROUND & AIMS: Recent evidence highlights the effects of obesity, diabetes and hypertension in the development of Alzheimer's disease. Involuntary body weight changes in patients with different stages of dementia can be related to clinical factors of the patient per se or support from their caregivers. Understanding the interactions among factors is important to establish a monitoring paradigm to guide treatment strategies. METHODS: A total of 345 patients with very mild (n = 224) and mild stage (n = 121) dementia were enrolled from a multi-disciplinary dementia clinic. Clinical data (comorbidities, Mini-Mental State Examination [MMSE] scores, neuropsychiatric inventory [NPI] scores, eating behavior questionnaire), nutritional state (Mini-Nutritional Assessment [MNA] or MNA short form [MNA-SF]) and body mass index (BMI) were recorded. Nutritional state and BMI served as the two major outcome measures, and factors for analysis included diagnosis, dementia severity and clinical data. RESULTS: There was a significant correlation between MNA-SF and MNA (r = .898, p < 0.01), but a 24% mismatch in case dislocation was found using the at-risk or malnutrition criteria. Factors related to obesity included male sex, higher MNA-SF and MNA scores, diabetes mellitus and hypertension, while acceptable discrimination for obesity (BMI≧23 kg/m2) was obtained with a MNA-SF score of 12/13 or MNA score of 21/22. NPI was the only independent factor related to both MNA-SF (ß = -.06, P < 0.001) and MNA (ß = -.1, P < 0.001). A BMI of 22-23 kg/m2 was adequate in this group of patients with early stage dementia from nutritional and comorbidity perspectives. After controlling for BMI, the patients with advanced dementia had higher swallowing problem and appetite change scores. CONCLUSIONS: In these patients with early stage dementia, a higher BMI indicated adequate nutritional status and higher MMSE, but also higher rates of comorbidities, diabetes mellitus and hypertension.

[The Relationship Between Diet Nutrition Knowledge and Demographic Characteristics in Family Caregivers of Patients With Dementia].

BACKGROUND: Although the general-care knowledge of family caregivers related to dementia had been studied, little attention has been given to understanding the knowledge of caregivers related to dementia diet nutrition. This knowledge is important to help caregivers handle the eating and nutrition problems of people with dementia (PwD). PURPOSE: The purpose of this study was to explore the dementia diet nutrition knowledge of family primary caregivers and to analyze whether demographic characteristics of caregivers and/or the dementia stages of PwD have a relationship with dementia diet nutrition knowledge. METHODS: A descriptive and cross-sectional study using a questionnaire survey was conducted. A total of 220 primary family caregivers of people with dementia were recruited. RESULTS: Results showed that the average total score for the 13 questions on diet nutrition knowledge was 71.85%. Moreover, only 28.2% of the participants answered the question "Malnutrition is a significant risk during the early stage of dementia" correctly. In addition, the findings showed significant differences in the diet nutrition knowledge of participants based on education level (F = 3.989, p < .05) and the use of foreign (non-Taiwanese) caregivers (t = -2.919, p < .01). CONCLUSIONS: The participants had sufficient overall diet nutrition knowledge of dementia. However, they lacked knowledge in specific areas. Family caregivers with higher levels of education and those who hired foreign caregivers had better knowledge scores. The results may be used as a reference for nurses providing dementia dietary education. It is recommended that special attention be given to dietary education when patients are at the early onset phase of the disease and when caregivers have a lower level of education in order to improve the overall quality of dementia dietary care in the community.

Cognitive Function and Quality of Life in Community-Dwelling Seniors with Mild Cognitive Impairment in Taiwan.

The aims of this study were to examine the relationships between overall cognitive function and the quality of life (QOL) domains, and to compare the differences in these by age, gender, and educational level in community-dwelling seniors in Taiwan. A cross-sectional study was conducted, with the participants screened and recruited from Southern Tainan. The Saint Louis University Mental Status Examination was used to screen the cognitive status of the participants. A total of 144 seniors participated in this study were assessed using the Taiwanese version of WHOQOL-BREF. The results showed that the participants performed better in the cognitive domains of "figure identification" and "orientation" while they performed poor in "delayed recall" and "immediate paragraph recall". No significant relationship between cognitive function and overall QOL, but a positive relationship between cognitive function and the physical health domain of QOL was found. The findings of this study provide valuable information for community healthcare providers.
