International Journal of Clinical Case Reports, 2025, Vol.15, No.5, 219-227 http://medscipublisher.com/index.php/ijccr 223 The quantitative data obtained from standardized scales and surveys were analyzed through statistical methods, including descriptive statistics, regression analysis, and structural equation models, to identify the relationships and influencing factors among variables such as anxiety, depression, and quality of life (Coin et al., 2021; Durante et al., 2023). By combining these two types of methods, cross-validation of results can be carried out, reliability can be enhanced, and more specific references can be provided for public health policies and elderly care interventions. 5 Case Summary and Discussion 5.1 The positive and negative impacts of home isolation on the health of elderly patients Home quarantine has both adverse and positive aspects for the health of the elderly. On the negative side, most studies have mentioned reduced exercise, increased sedentary time, deterioration of chronic diseases, and elevated risks of depression, anxiety, loneliness, and cognitive decline-especially among people with dementia or those lacking social support (Table 1) (Cagnin et al., 2020; Mendoza-Ruvalcaba et al., 2022). Furthermore, reduced social interaction and difficulties in seeking medical treatment have further exacerbated these problems, leading to functional decline and increasing the stress on caregivers (De Maio Nascimento et al., 2022). Some elderly people have demonstrated good psychological adjustment and adaptability. Studies show that compared with young people, they experienced relatively less stress and negative emotions during isolation, which might be attributed to their richer life experiences and more mature coping styles (Cheng and Zhang, 2021; Ouanes et al., 2021; Sterina et al., 2021). Positive changes also include re-recognizing the value of life, achieving spiritual growth, and developing new self-care habits or engaging in family activities (Gholamzad et al., 2021). 5.2 Correlation between healthy behaviors and quality of life During the quarantine period, there is a clear connection between the health behaviors and quality of life of the elderly. Reduced exercise, poor dietary habits and intensified social isolation are all closely related to the decline in physical and mental health, including an increased incidence of depression, anxiety and dysfunction (De Maio Nascimento et al., 2022). On the contrary, those elderly people who persisted in exercising or participated in intellectual activities usually maintained a better emotional state and daily functions (Di Santo et al., 2020). At the same time, positive coping styles-such as seeking positive meaning, maintaining social connections (even online), and participating in meaningful activities-can help mitigate the adverse effects of isolation. Elderly people with higher psychological resilience or stronger social support have less psychological distress and higher life satisfaction (Cheng and Zhang, 2021; Sterina et al., 2021). 5.3 Policy and practical significance The research results are of great significance both in terms of policy and practical application. Promoting telemedicine services is crucial for maintaining continuous treatment, especially for the elderly with chronic diseases or cognitive impairments. Telemedicine can help track health conditions, provide psychological support and relieve the pressure on caregivers. However, some problems still need to be addressed, such as the unfamiliarity of the elderly with electronic devices (Ouanes et al., 2021). Family exercise programs should be encouraged and the use of virtual or community exercise resources should be expanded to slow down physical and functional decline (Di Santo et al., 2020; Mendoza-Ruvalcaba et al., 2022). Finally, strengthening social support-such as regular contact, digital communication and community care-can help reduce loneliness and improve the mental health of isolated elderly people (Cheng and Zhang, 2021; Gholamzad et al., 2021). 6 Research Limitations and Improvement Directions 6.1 The case samples are limited and insufficiently representative Many studies on the impact of home quarantine on the elderly often have a small number of participants or do not cover a wide enough group. For instance, some studies only selected the elderly from a certain region, specific elderly care institutions, or those who could use electronic devices as subjects, resulting in the research
