Self-management factors associated with quality of life among women with endometriosis: a cross-sectional Australian survey

STUDY QUESTION: What self-management factors are associated with quality of life among women with endometnosis? SUMMARY ANSWER: Greater self-efficacy was associated with improved physical and mental quality of life. WHAT IS KNOWN ALREADY: Women with endometriosis have an impaired quality of life compared to the general female population. However, most studies have investigated quality of life in a hospital or clinic setting rather than a community setting and the association between self-management factors and quality of life have not, to date, been investigated. STUDY DESIGN, SIZE, DURATION: A cross-sectional, population-based online survey was performed, which was advertised through women's, community and endometriosis-specific group. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 620 women completed the survey for this study. Mental and physical quality of life was assessed using the standardized SF36v2 questionnaire. Self-management factors included self-efficacy, partners in health (active involvement in managing the condition) and performance of self-care activities. Treatment approaches included the use of hormonal treatment, pain medications and complementary therapies and whether the participant had a chronic disease management plan. Hierarchical regression analyses were used to examine whether self-management and treatment factors were associated with quality of life. MAIN RESULTS AND THE ROLE OF CHANCE: Both physical and mental quality of life were significantly lower among women with endometnosis compared to the mean scores of the general Australian female population (P < 0.001). Physical quality of life was positively associated with income sufficiency (P < 0.001) and greater self-efficacy (P < 0.001), but negatively associated with age (P < 0.001), pain severity (P < 0.001), use of prescription medications (P < 0.001), having a chronic disease management plan (P < 0.05) and number of self-care activities (P < 0.05). Mental quality of life was positively associated with being older (P < 0.001), partnered (P < 0.001), having a university education (P < 0.05), increasing self-efficacy (P < 0.001) and higher partners in health scores (P < 0.001). LIMITATIONS, REASONS FOR CAUTION: Results are derived from a cross-sectional study and can only be interpreted as associations not as causal relationships. The sample was more educated, more likely to speak English and be born in Australia than the general Australian female population of the same age, which may influence the generalizability of these results. WIDER IMPLICATIONS OF THE FINDINGS: This study investigated a knowledge gap by investigating quality of life of women with endometnosis in a large community sample. Self-efficacy was significantly associated with both physical and mental quality of life. Supporting women with endometriosis to improve self-efficacy through a structured chronic disease management programme may lead to improvements in this aspect of wellbeing.
