Objective: To assess the distribution of widespread pain, tender points (TP), and Fibromyalgia (FM) in young African American (AA) and Caucasian (C) women.
Methods: A community population of 1334 young (21-26 yrs old) women (684 African American and 650 Caucasian) was surveyed and classified for body pain spread [chronic widespread pain (CWP), axial regional chronic pain (RCP), nonaxial RCP, or no pain]. Of these women, 553 were examined for tender points, based on American College of Rheumatology criteria.
n Overall, 5.6% reported chronic widespread pain, while 22% reported axial regional chronic pain, and 16% reported nonaxial regional chronic pain.
n From the chronic widespread pain group, 57% were confirmed as FM cases.
n Caucasian women had significantly more tender points and greater tender point pain score than African-American women (p <= 0.005).
n Overall FM prevalence was 2.4% (95% confidence interval: 1.7-3.5%)
n With 3.0% overall FM prevalence in African-American and 2.0% in Caucasian women.
n Increase in body pain and tenderness was significantly associated with decreased subjective socioeconomic status (SSS), worse self-reported health, greater impact of premenstrual symptoms on activities, and greater depressive symptoms.
n The effect of depressive symptoms on pain differed by race.
n Widespread pain and tenderness is highly prevalent in these young women.
n Racial differences seem to exist.
n Caucasian women had significantly increased tenderness while African-American women had more widespread pain.
n The association of depressive symptoms and pain was stronger in African-American women.
n Racial differences emerged relatively early in these young women.
