The association between comorbidities and stigma among breast cancer survivors.

This study aimed to explore the association between types and numbers of comorbidities and stigma among breast cancer survivors (BCSs). A cross-sectional study was conducted among 937 BCSs in Shanghai Cancer Rehabilitation Club. All participants were asked to fill in an online questionnaire including Stigma Scale for Chronic Illnesses 8-item version (SSCI-8) and questions on sociodemographic characteristics and health status. Multivariate linear regression was used to analyze the association between comorbidities and stigma, adjusting for confounding factors. Results showed that nearly 70% of the participants had one or more comorbidities. The participants with stroke, digestive diseases or musculoskeletal diseases had significantly higher stigma than those without the above comorbidities. In addition, stigma was higher among survivors in the group with a greater number of comorbidities. Thus, it is important to strengthen the management of stigma in BCSs, especially for those with comorbidities.
