Chronic diseases bring significant changes to both the child and their parents. Compared to the child, the child's parents are more likely to perceive the child's vulnerability. Even though there is medical evidence to suggest that children with chronic diseases are in a stable state, parents still believe that their children are very vulnerable to disease, injury, or death, that is, parental perceptions of child vulnerability (PPCV). PPCV is commonly present in children with chronic diseases and can have a significant negative impact on both the child and their parents. This paper reviews the concept and evaluation tools of PPCV in children with chronic diseases, and focuses on the negative impact and intervention strategies of PPCV on children and their parents, so as to provide reference for the evaluation, prevention, and intervention of PPCV in children with chronic diseases.

Objective:To analyze the research hotspots on domestic and international chronic illness trajectory models (CITM) .Methods:Literature on CITM was retrieved from the Web of Science Core Collection and China National Knowledge Infrastructure. CiteSpace 6.2.R4 was used to analyze research institutions, authors, and keywords visually.Results:A total of 1 316 articles were obtained. The majority of the literature originated from foreign countries. Research hotspots on CITM included chronic diseases, anxiety, and quality of life. International studies focused on risk research, while domestic studies emphasized self-care, self-efficacy, and complications.Conclusions:Research on CITM in China is still in its infancy. Both domestic and international efforts need to enhance collaboration among institutions, authors, and disciplines to conduct in-depth research on CITM. Chronic illness, anxiety or depression, and quality of life are likely to become research hotspots in the field of CITM both domestically and internationally.
