To examine the relationship between weight loss and problems with oral intake in institutionalised older adults.
A 1-year longitudinal observational study.
Data were obtained from a prospective study conducted in three nursing homes and two long-term care facilities in Japan. Participants' problems with oral intake were assessed using items published in 2021 by the Japanese Ministry of Health, Labour and Welfare. Baseline and follow-up factors were compared between individuals who experienced a weight loss of 5% or more and those who did not. Separate multivariable logistic regression models were constructed for each oral intake assessment item to examine its independent association with weight loss of 5% or more, accounting for transitions in each item between baseline and the 1-year follow-up.
In total, 172 institutionalised older adults were included in the analysis. Among them, 57 (33.1%) participants experienced a weight decrease of 5% or more. The emergence of somnolence or clouding of consciousness during meals at the 1-year follow-up in participants without these signs at baseline was independently associated with a weight loss of 5% or more, after adjustment for baseline characteristics.
Recognising signs of somnolence or clouding of consciousness during meals may be useful for the early detection and prevention of weight loss in institutionalised older adults.
Early detection of individuals at risk is essential to prevent significant weight loss and its associated adverse outcomes. Recognising somnolence or clouding of consciousness during meals may enable earlier detection and intervention to prevent weight loss and improve the quality of care for older adults.

No patient or public contribution.
Ischaemic heart disease (IHD) is a leading cause of morbidity and mortality worldwide. Despite strong recommendations, the implementation rate of outpatient cardiac rehabilitation (CR) in Japan remains low. Mobile health technologies, such as Personal Health Record (PHR) applications combined with wearable devices, may enhance adherence to rehabilitation programmes. This study aims to evaluate the effectiveness of a continuous support programme that integrates a PHR app and counselling services in improving the continuation rate of outpatient CR and exercise tolerance in patients with IHD.
This is a single-blind randomised controlled trial with a parallel-group design. A total of 72 participants with IHD will be recruited from the outpatient departments of Maebashi Red Cross Hospital, Gunma Saiseikai Maebashi Hospital, Okayama University Hospital, Okayama Red Cross Hospital, Momoyama-kai Ono Internal Clinic, Hiroshima University Hospital, Tshuyama Jifu-kai Tsuyama Chuo Hospital and Shinpu-kai Tamashima Chuo Hospital. Participants will be randomly allocated to either the intervention group, which will receive a wearable device, a PHR app, counselling services and a rehabilitation notebook, or the control group, which will receive a wearable device and a rehabilitation notebook without the PHR app and counselling. The primary outcome is the change in peak oxygen uptake from baseline to 150 days. Secondary outcomes include changes in anaerobic threshold, number of outpatient rehabilitation visits, daily steps and vital signs. Data will be analysed using a generalised estimating equations for primary outcomes and appropriate statistical tests for secondary outcomes, following an intention-to-treat approach.
Ethical approval for this study was obtained from the ethics committee of the Kyoto University Graduate School and Faculty of Medicine (C1669-1). In addition, permission to conduct the study was granted by the director of each participating institution. Participants will provide informed consent prior to participation. Findings will be disseminated through peer-reviewed journals, conferences and summary reports to stakeholders.
This trial is registered with the University hospital Medical Information Network (UMIN) Clinical Trials Registry (trial identifier: UMIN000055823).
