Background/Purpose: Lifestyle modifications, including of diet and exercise, have been widely disseminated for the prevention and treatment of chronic pain. However, the relationships between dietary habits and fibromyalgia (FM) impact, and psychosocial or quality of life (QoL) outcomes have not been well studied.
Methods: Participants in a large comparative effectiveness randomized trial of Tai Chi versus aerobic exercise for FM were recruited. Participants were excluded from this study if they had participated in any dietary intervention since the end of the original trial. The National Cancer Institute Diet History Questionnaire (DHQ-II past year recall without portion sizes) was used to assess diet quality, using the Healthy Eating Index 2010 that assesses compliance with the 2010 U.S. Dietary Guidelines for Americans (DGA). Associations of diet quality with the pre-intervention FM impact scores, various psychosocial and QoL measures, self-efficacy, and sleep quality (Table 1) were examined using Pearson’s correlation coefficient (r)
Results: A total of 26 female participants (mean age = 56 y; mean pre-intervention BMI = 29.6) were included in the analyses. Of which, six (3 in each intervention arm) participants reported that their diet has changed since the end of the original trial. Diet quality of these participants was better than general U.S. adult population (Table 2). Higher pre-intervention self-efficacy and physical health QoL were associated with higher diet quality (r = 0.62 and 0.32, respectively). Higher pre-intervention levels of anxiety and depression were associated with lower diet quality (r = -0.43 and -0.47, respectively). There were no significant associations between diet quality and pre-intervention severity of depressive symptoms, mental health QoL, sleep quality, or FM impact scores (Table 1).
Conclusion: Better diet quality as recommended by the 2010 DGA may be associated with more favorable psychosocial and physical health QoL outcomes in women with FM. Our results are consistent with a large cross-sectional study in women with FM from Spain (J Acad Nutr Diet. 2017 Mar;117(3):422-432). Future studies evaluating the effects of healthy dietary patterns on psychosocial and physical outcomes in individuals with FM are warranted.
