Considering that Korea’s aging population is rapidly increasing, health serves as an indicator of older adults’ quality of life, and dietary life directly affects their health. For health maintenance and improvement, preventive healthcare measures including safe food selection and nutritional supply are needed. This study aimed to evaluate the effect of senior-friendly diet on nutrition and health status improvement in older adults receiving community care. A total of 180 older adults were analyzed, with 154 and 26 in the senior-friendly diet intervention group and the general diet group, respectively. Surveys, blood tests, and frailty evaluations were conducted before and after the study. After 5 months of intervention, the blood status, nutrient intake, and frailty level were evaluated. The participants’ mean age was 82.7 years, and 89.4% of them were living alone. In both groups, energy, protein, vitamin A, vitamin D, vitamin C, calcium, and magnesium intake were insufficient initially but generally improved after the intervention. Especially in the intervention group, energy, protein, vitamin D, vitamin C, and folic acid intake significantly increased. The frailty level also slightly improved, and the malnutrition rate was reduced. Even after the passage of time, the improvement effect size significantly differed between the groups. Therefore, resolving and supporting meals corresponding to the physiological needs of the older adults has a great impact on improving their quality of life, and such special consideration is a reasonable way to respond to a super-aged society.

Objectives: The global rise in dementia prevalence is escalating the socioeconomic burden, prompting efforts in prevention and treatment. This study aimed to evaluate the effects of an 8-week oral nutrition supplement (ONS) program with or without a multi-domain intervention program (MIP) in patients with mild cognitive impairment. Methods: Forty-nine patients with mild cognitive impairment were divided into three groups: (1) ONS (ONS), (2) ONS+MIP (ONS+MIP), and (3) control (CON). Korean-style dementia prevention MIP was used in the ONS+MIP group. Two packs of ONS per day were provided to the ONS group during the intervention period. Cognitive function, nutritional evaluation, body composition analysis, and physical performance were measured. The paired t-test and one-way analysis of variance were used for statistical analyses. Results: A final analysis was performed on the final 46 participants. After intervention, the cognitive function test (Repeatable Battery for the Assessment of Neuropsychological Status, RBANS) scores of the ONS+MIP group were significantly increased compared to the baseline scores. However, no significant changes were observed in the ONS and CON groups. Eating behavior and food quality also improved in the ONS+MIP group, with a significant difference among the three groups. There was no significant change in body composition in all groups; however, grip strength (left hand), muscular endurance, and the total SPPB score improved in the ONS+MIP group. The total SPPB score decreased in the CON group. Conclusions: Along with ONS intake, intensive education and continuous monitoring through multi-domain interventions are important to improve cognitive function.

Objective: As global populations age, nutrition management is important for healthy aging. Digital technologies, including mobile applications, web-based platforms, messaging tools, and artificial intelligence (AI)-enabled systems, are used in personalized nutrition interventions. However, evidence on their characteristics, effectiveness, and user experiences remains limited. This scoping review examined technology-based personalized nutrition interventions for older adults.Methods: This review followed the Joanna Briggs Institute methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. PubMed, Embase, and Web of Science were searched for studies published from January 1, 2010, to June 30, 2026. Among 2,727 records, 2,044 were screened after duplicate removal, 28 full-text articles were assessed, and 13 articles representing 12 studies were included.Results: Technologies included mobile, messaging, web-based, information and communications technology, tablet-based, and AI-supported systems. Interventions involved dietary recording, personalized feedback, remote counseling, coaching, and self-monitoring. Outcomes included dietary intake and quality, nutritional status, physical function, frailty, cognition, cardiometabolic indicators, engagement, usability, and acceptability. Findings were more consistent for dietary behaviors and individualized nutrition management. Evidence for physical function, frailty, cognition, cardiometabolic health, and quality of life was limited and often based on small or multidomain studies. Familiar interfaces and professional support were accepted, whereas low digital literacy, complex navigation, and limited food databases were barriers.Conclusion: Digital personalized nutrition interventions may support dietary behavior change and individualized nutrition management in older adults. Larger studies and user-centered systems addressing digital literacy, usability, cultural context, and AI-feedback validation are needed.

Objective: The rapid global aging trend has led to a substantial increase in the prevalence of frailty among older adults. We developed a mobile app-based multidomain intervention (MI) program as part of a South Korean study to prevent the progression of frailty and aging-related diseases using a digital MI (SUPERAGING). We aim to evaluate the feasibility of the SUPERAGING app-based intervention in prefrail or frail older adults. Methods: We will recruit 40 community-dwelling older adults aged 60 to 90 years classified as frail or prefrail according to the Modified Fried frailty criteria. Participants will be randomly assigned to intervention and control groups at a 1:1 ratio. The intervention group will receive a personalized program through the SUPERAGING digital platform, comprising four components: disease management, cognitive training, physical exercise and nutritional intervention for 16 weeks. The control group will receive standard lifestyle education only. The primary outcomes are adherence, retention, and recruitment rates. The main secondary outcomes are frailty, disability, cognitive function, physical performance, nutritional assessment, mood, quality of life, vascular risk factors, and occurrence of aging-related diseases. There will be an exploratory evaluation of biological aging markers. Results: The intervention program will be considered feasible if the following success criteria are met: (a) a retention rate of 70% or higher, (b) an adherence rate of 70% or higher, and (c) a recruitment rate of 50% or higher. Conclusions: The results will provide information on the applicability of a MI using a mobile app targeting older adults with prefrailty or frailty.
