Dietary Inflammatory Index scores are associated with pressure pain hypersensitivity in women with fibromyalgia
This 2020 cross-sectional study examined 95 women diagnosed with fibromyalgia syndrome (FMS) and 98 menopause-status matched controls, to learn about the relationship between an anti-inflammatory diet profile and the pressure pain thresholds (PPTs) of tender point sites and other fibromyalgia-related symptoms in patients with FMS. The study evaluated disease severity, sleep, fatigue, anxiety, central sensitisation, Dietary Inflammatory Index (DII) and the PPTs of tender point sites and self-reported global pain levels (through algometry and visual analog scale). The DII score was associated with the PPTs of tender point sites including the occiput, trapezius, zygapophyseal joint, second rib, gluteus, greater trochanter, and knee using linear regression analysis (after variable adjustments) and using analyses of covariance (significant association between the PPTs of the above tender point sites with the DII score quartiles in patients with FMS). However, no significant differences were found for the cases or controls between the DII score and the remaining clinical symptoms or between the DII score quartiles with other symptoms in patients with FMS. The writers conclude that a pro-inflammatory diet was associated with pain hypersensitivity in patients with FMS.
