Abstract

Type 2 diabetes is a common chronic disease, which has a negative health impact and results in enormous economic burden. The prevalence of type 2 diabetes is increasing dramatically and it affects older people disproportionately. The healthcare system in China is faced with an overwhelming burden due to a large ageing population, high prevalence of diabetes and limited healthcare resources. Self-management has been widely accepted as the cornerstone of the clinical management of type 2 diabetes. Since self-management usually involves complex behaviour change and can be emotionally challenging, effective education is essential to facilitate this transition. However, there has been no existing program of type 2 diabetes self-management for older patients in China until now. Furthermore, the generalisation of any health education programs is often hampered due to limited healthcare resources in China.

The primary purpose of this study was to develop a socially and culturally suitable self-management program, which addressed self-efficacy and social support to facilitate behaviour change and subsequent health improvement, for older people with type 2 diabetes living in the community in China. The secondary purpose was to test a feasible delivery model of the program through involvement of peer leaders and existing community networks. This study was conducted in three phases. Phase one gathered information about barriers related to self-management behaviours and help needed to address them, from the perspective of older people with type 2 diabetes and community health professionals, through focus group discussion. Data from Phase One, together with guidelines of the selected theoretical frame work, results from an extensive literature review, and experiences of previous relevant studies provided the basis for development of a peer-led type 2 diabetes self-management program (Phase Two). Phase Three involved a pre-test, post-test non-equivalent control group design to test the effectiveness of the self-management program on older people with type 2 diabetes in the community. The impact of the program on peer leaders was examined using a one group pre-test, post-test design. In addition, evaluation of the program from peer leaders’ and older people’s perceptions was conducted through a post-test questionnaire.

Older people with type 2 diabetes and health professionals expressed broadly the same concerns, which were: social support; confidence to practice self-management behaviours; self-management behaviours; barriers to self-management behaviours; and advice for ongoing health education. However, their points of view were not always identical and different emphases were identified.

The peer-led program produced significant improvement in social support, self-efficacy, self-management behaviours and depressive status in the experimental group, as compared to the non-equivalent control group. However, there was no significant effect on quality of life nor health care utilisation. Therefore, the effectiveness of the program among older people with type 2 diabetes was partially confirmed. In addition, the participants were supportive, giving positive feedback about the program. Suggestions for future improvement were provided as well.

After receiving specific peer leader training and assisting in most of the delivery process of the program, the peer leaders improved, significantly, in overall self-management behaviours and in specific areas of social support and self-efficacy, though they did not improve in depressive status, quality of life and health care utlisation. In addition, these peer leaders enjoyed being peer leaders, and gave very positive feedback about the whole program.

In conclusion, this study has implications for understanding and facilitating self-management behaviours for older people with type 2 diabetes in China. The peer-led self-management program was effective in improving levels of self-efficacy, social support, self-management behaviours and depressive status among older people with type 2 diabetes living in the community in China. The delivery process involving peer leaders was deemed feasible to implement within the health care system in China. The program is suitable to be used by community health professionals in their practice in China. The study also has potential wider benefit to nursing practice and global health practice.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
