65 Years Older

The goal of this clinical trial is to assess the effectiveness of an intervention (combination of behavioural recommendations and technical measures) in reducing personal exposure to heat and air pollution and related health effects in older adults with hypertension. The main questions it aims to answer are: * Does the intervention (combination of behavioral recommendations for heat mitigation) reduce personal ambient temperature exposure, measured using a wearable device (iButton)? * Does the intervention (combination of behavioral recommendations for air pollution mitigation and use of indoor air cleaners) reduce indoor exposure to air pollution, measured using indoor air quality sensors (Purple Air)? * Does the intervention (combination of behavioral recommendations for heat mitigation) improve the abnormalities in circadian blood pressure variation experienced by older adults with hypertension, assessed using advanced actigraphy? Researchers will compare measurements between older adults with hypertension carrying out their daily activities in the absence of intervention (control group), those carrying out their daily activities with behavioural recommendations (recommendation intervention group) and those carrying out their daily activities with both behavioural recommendations for heat mitigation and continuous use of indoor air cleaners in their house (heat and air pollution mitigation intervention group) to see if changes in temperature exposure and sleep are different between intervention groups. Participants will: * Wear the wearable devise for continuous personal ambient temperature monitoring (ibutton) daily for a period of three months * Have their core temperature measured using an eCelsius medical capsule in three repeated assessments * Have their blood pressure, oxygen saturation, ECG and heart rate variability measured using 24-hour advanced actigraphy in three repeated assessments * Provide samples of urine and blood biomarkers in three repeated assessments.

The study is planned to be completed over three years and will focus on 500 hospitalized older adults with a diagnosis of CHF. The Biopsychosocial model will be used to conduct this study. Phase 1: This phase aims to determine the incidence rates of sarcopenia, frailty/social frailty among hospitalized older adults, and to compare these outcomes in gender differences. Sarcopenia will be identified according to the AWGS guidelines, while clinical characteristics, including ejection fraction, stage of CHF, and comorbidities, will be collected via chart review using the 2024 Guidelines of the Taiwan Society of Cardiology(Y. H. Li et al., 2024). Frailty and social frailty will be measured using the CFS, Tilburg Frailty Indicator (TFI), and Makizako's Social Frailty Questionnaire, respectively, and physical activity levels will be assessed with the International Physical Activity Questionnaire - Short Form (IPAQ-S). To develop a predictive model examining risk factors for social frailty and health outcomes, with a focus on gender differences, we will employ Structural Equation Modeling (SEM). SEM allows for the analysis of complex relationships among variables, facilitating a comprehensive understanding of how these factors interact differently across genders. Phase 2: A quasi-experimental design will be implemented, involving 174 hospitalized older adults with low social frailty scores. Participants will be randomly assigned to one of three groups. Group 1 will use the ChatGPT app for 15-30 minutes daily, with the app actively monitoring their emotional status and automatically notifying the research team and family members if signs of negative mood are detected. Group 2 will be encouraged to increase their social participation through community-based activities. The Control Group will continue their routine lifestyle without additional interventions. Before the intervention, one-on-one training will be provided to Group 1 participants on how to use ChatGPT. Key outcome measures, including mood status (loneliness, anxiety, and depression), physical activity (assessed via IPAQ-S), overall frailty (CFS \& TFI), social frailty scores, and other health indicators, will be assessed at baseline and immediately post-intervention. Phase 3: The aim of this phase is to monitor and compare the longitudinal health outcomes of interventions among the three groups. Key health outcomes will be assessed and compared every three months over a one-year period.

Frailty-encompassing sarcopenia, physical, psychological, and social frailty-is common among older adults with congestive heart failure (CHF) and contributes to adverse outcomes such as rehospitalization, mortality, and poor quality of life. However, few studies have compared these conditions in congestive heart failure (CHF) patients, particularly in elderly women in Taiwan, and effective, tailored Information and Communication Technology (ICT) interventions are scarce. This three-year study aims to (1) compare baseline characteristics and incidence rates of sarcopenia, physical, psychological, and social frailty among hospitalized older women with congestive heart failure (CHF) in metropolitan versus rural hospitals; (2) evaluate risk factors associated with physical, psychological, and social frailty; (3) monitor health outcomes (rehospitalization, mortality, quality of life) during a one-year follow-up; and (4) assess the effectiveness of an Information and Communication Technology (ICT) intervention designed to enhance social connectivity and emotional well-being. In Phase 1, clinical data-including ejection fraction, congestive heart failure (CHF) stage, and comorbidity -will be collected using the 2024 Guidelines of the Taiwan Society of Cardiology, while sarcopenia will be identified via Asian Working Group for Sarcopenia (AWGS) guidelines. Physical, psychological, and social frail will be measured with the Tilburg Frailty Indicator (TFI) and Makizako's Social Frailty Questionnaire, respectively, and physical activity will be assessed using the IPAQ-S. Phase 2 will involve quarterly follow-ups over one year to compare health outcomes between metropolitan and rural settings, and to develop a predictive model of these outcomes. Phase 3 employs a quasi-experimental design with 90 participants randomized into three groups: an Information and Communication Technology (ICT) intervention group (using a dedicated app for at least 15 minutes daily, which monitors emotional status), a community-based social participation group, and a control group maintaining routine care. Key outcomes (mood, physical activity, frailty measures, and clinical status) will be assessed at baseline, immediately post-intervention, and three months thereafter. This study is expected to identify significant differences between settings and demonstrate that a tailored Information and Communication Technology (ICT) intervention can improve social connectivity and clinical outcomes in older women with congestive heart failure (CHF).
