Objective:To understand the current situation of female cancer survivors′ self-advocacy and analyze its influencing factors.Methods:Convenience sampling was used. From August to November 2021, 243 female cancer survivors from 10 tertiary A hospitals in Jiangsu Province were selected as the research objects. The general information questionnaire and the Female Self-Advocacy in Cancer Survivorship (FSACS)were used for the survey. Multiple stepwise linear regression was used to analyze the influencing factors of female cancer survivors′ self-advocacy rights.Results:The self-advocacy score of this group of female cancer survivors was (82.42±10.42); the results of multiple stepwise linear regression analysis showed that education level was an influencing factor for female cancer survivors′self-advocacy ( P<0.05), but age, marital status, number of children, work status, family monthly income, reimbursement method, illness time, disease diagnosis, and disease stage had nothing to do with female cancer survivors′ self-advocacy( P>0.05). Conclusions:Female cancer survivors′ self-advocacy is affected by their educational level.It is recommended that medical staff pay attention to patients with low education level, provide personalized guidance according to their conditions, and encourage them to actively obtain external information, seek effective communication and external support, so as to improve Self-advocacy ability.

Abstract Public physical education teaching has adopted modern concepts and approachs of physical training to highlight the importance and effectiveness of physical education in colleges and universities in China. These courses have placed an emphasis on the need to attend to the structural integrity of the human body, optimizing the basic action mode and the efficient transmission of the power chain in motion. From the perspective of curriculum education, it is helpful to update ideas surrounding the public physical education curriculum in colleges and universities to enrich the content of public physical education courses provided by these institutions and to improve the scientific nature of training, while also enhancing the physical fitness of college students and promoting lifelong sports consciousness. However, there is insufficient explanation and implementation of modern physical training concepts and approachs into the teaching and process of public sports in colleges and universities. It will be beneficial to improve its top level design, increase policy support, provide better facilities, strengthen the construction of teachers, actively organize enjoyable physical fitness competitions, enrich the teaching content system and clear on the positioning of college physical education, in order to promote the fundamental tasks of school based physical education and the value of school sports. This is also important to ensure a renewal of the concept of the public physical education curriculum in our country, and encourage reform of the curriculum content, teaching mode and teaching methods, while also highlighting the essential function of physical training.
