Objective: To investigate diet quality and its relationship with 1) fibromyalgia impact, and 2) psychological health in patients with fibromyalgia who participated in a randomized controlled trial (RCT) of Tai Chi versus aerobic exercise for fibromyalgia. Methods: A cross-sectional study enrolled participants from a RCT. Diet quality and fibromyalgia symptoms were assessed using the Healthy Eating Index 2010 (HEI-2010) and Revised Fibromyalgia Impact Questionnaire (FIQR), respectively. Retrospective analyses were performed using Spearman’s coefficient (r) to examine the association of diet quality with pre-intervention FIQR, psychological variables, and quality of life. Results: Twenty-six female participants (mean age = 56 y; mean pre-intervention BMI = 29.6) of 223 trial participants (11.7%) were included in the analyses. Higher diet quality was associated with higher pre-intervention Chronic Pain Self-Efficacy scores (r=0.62, p=0.01), and lower Hospital Depression scores (r=-0.47, p=0.02). There were no significant associations between diet quality and pre-intervention severity of depressive symptoms, mental or physical health quality of life, sleep quality, or FIQR scores. Conclusion: Preliminary results suggest a positive association between diet quality and self-efficacy and psychological health in women with fibromyalgia. Future prospective studies are needed.","journal":"Journal of Maine Medical Center","year":2020,"id":115498,"datarank":0.16479184330021646,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"self_citation_contribution":0.16479184330021646,"citation_network_contribution":0.0,"self_endowment_contribution":0.16479184330021646,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9555,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":376734,"name":"Lori Lyn Price","orcid":"0000-0003-0664-8978","position":1,"is_corresponding":false},{"id":541088,"name":"Chenchen Wang","orcid":"0000-0003-1817-6656","position":2,"is_corresponding":false},{"id":541089,"name":"Mei Chung","orcid":"0000-0002-5583-2870","position":3,"is_corresponding":false},{"id":541087,"name":"Andrew R.
