In the digital age, electronic health literacy (eHealth literacy) of community-dwelling older people plays a potentially important role in their health behaviors which are critical for health outcomes. Researchers have documented that self-efficacy and self-care ability are related to this relationship. This study aimed to assess the relationship between eHealth literacy and health promotion behaviors among older people living in communities and explore the chain mediating role of self-efficacy and self-care ability. For this cross-sectional study, we used data from 425 older adults at 3 communities in Qingdao, Shandong Province in Northeastern China, from June to September 2021. Path analysis using the structural equation model was performed. We found that eHealth literacy was significantly associated with health promotion behaviors in older people. Additionally, eHealth literacy indirectly affected health promotion behaviors through self-efficacy and self-care ability, respectively. In addition, the chain mediation effect was identified in the relationship of eHealth literacy and health promotion behaviors: eHealth literacy→ self-efficacy→ self-care ability→ health promotion behaviors. These findings offer promising directions for developing interventions to modify older adults’ health behaviors through enhancing their eHealth literacy. These interventions should integrate components that target improving the self-efficacy and self-care ability of older people.

In terms of social and psychological health of enterostomy patients during hospitalization and discharge transition period, the degree of social isolation in patients during discharge transition period is higher than that during hospitalization period, which is usually manifested by poor self-perception of body image changes. Self-esteem (shame) frustration, severe negative emotions, low psychosocial adjustment, and other factors are closely related to postoperative complications, coping self-efficacy, social support level, family living conditions, and other influencing factors. This is an important reason why patients are difficult to adapt to ostomy life and low quality of life. At present, it is believed that the social isolation related evaluation scale can be used to understand the status quo of patients with social isolation and provide nursing guidance, so as to better cope with the adverse medical outcomes caused by social isolation.
