The feasibility of an anti-inflammatory diet in endometriosis: barriers and facilitators perceived by endometriosis patients.

What is the feasibility of an anti-inflammatory diet in women diagnosed with endometriosis? Qualitative study using semi-structured focus groups and individual interviews among patients with endometriosis. Transcripts of the focus groups and interviews were thematically analysed using ATLAS.ti 9. To identify and structure the ideas and views from the focus groups and interviews, two behavioural change models were used. The Capability Opportunity Motivation Behaviour (COM-B) model and domains of the Theoretical Domains Framework (TDF) helped to identify factors that make adherence to an anti-inflammatory diet more or less feasible for women with endometriosis. The study population consisted of 23 patients with endometriosis. Numerous perceived barriers and facilitators were identified from all COM-B components and 13 out of 15 TDF domains. Knowledge and social influences were the most prominent TDF domains. Key barriers were eating with others; disbelief in a patients' own capability regarding specific dietary guidelines; concerns about taste; lack of knowledge on how to follow the diet; lack of noticeable beneficial effect; and lack of intention to follow the diet to full extent. Key facilitators were receiving social support; general confidence in a participant's own capabilities; knowing how and why to follow the diet; noticing beneficial effect; and belief that the diet would alleviate symptoms. Provision of knowledge, stimulating social support and enhancing self-efficacy should be emphasized. Overall, an anti-inflammatory diet in endometriosis patients, especially when identified barriers and facilitators are addressed in an intervention, is feasible.
