Factors associated with lymphedema self‐management behaviours among breast cancer survivors: A cross‐sectional study

Abstract

AbstractAims and ObjectivesThe purpose of this empirical study was to explore the current status and associated factors of lymphedema self‐management behaviours among Chinese breast cancer survivors.BackgroundBreast cancer‐related lymphedema is a lifetime concern for survivors and is currently incurable. Lifetime lymphedema self‐management takes a significant role in preventing development and progression of lymphedema. Understanding influencing factors of lymphedema self‐management behaviours can help to develop targeted intervention programs.DesignA multicentre cross‐sectional study.MethodsFrom December 2021 to April 2022, a convenience sample of 586 participants were recruited at four tertiary hospitals in four cities in China. Self‐reported questionnaires were used to measure socio‐demographic characteristics, disease‐and treatment‐related characteristics, lymphedema self‐management behaviours, lymphedema knowledge, illness perception, self‐efficacy, self‐regulation and social support. Descriptive analysis, bivariate analysis and hierarchical multiple regression were conducted. This study was registered at Chinese Clinical Trial Registry (ChiCTR2200057084), and was reported followed the STROBE checklist.ResultsBreast cancer survivors reported moderate level of lymphedema self‐management behaviours. Promotion of lymph reflux management was ranked the least performed self‐management behaviours, while the affected limb protection management ranked the most. 36.2% of self‐management behaviours was explained by exercise regularly, level of attention on lymphedema prevention, unclear about the tumour stage (vs. stage I), knowledge, self‐efficacy, emotional illness representation and social support.ConclusionsLymphedema self‐management behaviours of breast cancer survivors was insufficient. Performance of lymphedema self‐management varied with different socio‐demographic characteristics, along with different levels of knowledge, self‐efficacy, perception and social support. All these identified predictors should be reckoned in assessment and intervention of lymphedema self‐management behaviours.Relevance To Clinical PracticeThis study addressed that breast cancer survivors' lymphedema self‐management behaviours should be promoted. Focusing on identified predictors, further lymphedema surveillance, knowledge education or social facilitation programs are recommended to enhance their self‐management performance and adherence.
