- Objectives
This study aimed to investigate and compare factors associated with malnutrition according to the presence or absence of dementia in community-dwelling elderly people.
Methods
Needs assessment data from 311 long-term care insurance (LTCI) recipients (dementia group 203; non-dementia group 108) that participated in the second pilot program of the integrated care model in community care settings under the Korean LTCI system were used. Descriptive statistical analysis, independent t-test, and analysis of variance were conducted on the sociodemographic characteristics, health and functional status, and nutritional status of the dementia and non-dementia groups. Logistic regression analysis was conducted to identify factors associated with malnutrition in the dementia and non-dementia groups.
Results
Malnutrition occurred in 33.5% and 26.9% of participants in the dementia and non-dementia groups, respectively. In the dementia group, living with family rather than living alone (odds ratio [OR]: 3.81; 95% confidence interval [CI]: 1.50–9.66; P = 0.031), increase in Korean Activities of Daily Living (K-ADL) score (OR: 1.35; 95% CI: 1.17–1.55; P < 0.001), and increase in the Neuropsychiatric Inventory-Questionnaire score (OR: 1.02; 95% CI: 1.01–1.03; P = 0.005) were associated with a higher risk of malnutrition. In the non-dementia group, the risk of malnutrition increased as the K-ADL score increased (OR: 1.20; 95% CI: 1.04–1.39; P = 0.011) and in the depressed group (OR: 2.84; 95% CI: 1.04–7.74; P = 0.042).
Conclusions
The study results confirmed the necessity of nutritional management for community-dwelling LTCI recipients. When developing a nutritional management program, considering the differences in factors related to malnutrition between the dementia and non-dementia groups is important. This study proposes policies for improving the LTCI system in terms of nutritional management and the utilization of community resources.

- Objectives
This study was performed to investigate the relationship between foodservice staffing and foodservice quality in elderly care facilities.
Methods
Data was obtained from the Korean Long-term Care Institute Database and used to analyze 2,084 aged care facilities operating on-site foodservice. The presence of dietitians and staffing levels for cooking personnel were analyzed by categorizing size according to staffing criteria. Food service quality was assessed using food sanitation management and meal service provision as indicators. Descriptive statistical analysis, chi-square test, Fisher’s exact test, and Cochran-Mantel-Haenszel test were conducted to analyze relationships between staffing level and foodservice quality.
Results
Presence of a dietitian correlated with food sanitation management and meal service provision in groups with 30 or more recipients (P = 0.027, P = 0.049). Elderly care facilities with dietitians had better foodservice quality. After adjusting for size, the presence of dietitians was also found to correlate with food sanitation management (P = 0.024). Staffing levels for cooking personnel were found to correlate with meal service provision only in groups with 38 to 62 recipients. Institutions with larger staffs provided better meal service quality compared to those with basic staffing.
Conclusion
Inclusion of a dietitian and cooking staff size each contribute to enhanced foodservice quality in elderly care facilities, with dietitian inclusion showing a particularly significant association with food sanitation management. These findings suggest the need to revise current staffing and related regulatory standards to optimize deployment of foodservice personnel in elderly care settings. Future studies should focus on developing effective policies for securing qualified foodservice staff and establishing robust quality management systems to enhance overall foodservice quality in long-term care facilities.
