1531 Fibromyalgia: The Early Years. Symptoms in Childhood Before the Diagnosis

METHODS: An Internet survey, conducted by a FMS community organization, AFFTER (Advocates for Fibromyalgia Funding, Treatment, Education and Research), asked respondents about 7 different childhood symptoms. 463 women with FMS and 75 women without FMS completed the questionnaire. The FMS and non-FMS groups were compared with respect to the percentage reporting having had each symptom using the chi-square test of association, and with respect to the number of reported symptoms using the nonparametric Mann-Whitney test. A 0.05 significance level was used. All tests were two-sided.

RESULTS: Women with FMS were significantly more likely than women without FMS to report 6 of the 7 childhood symptoms. For women who reported at least 1 symptom, the FMS group reported significantly more symptoms than the non-FMS group (3 ± 2 versus 2 ± 1).

CONCLUSION: Women with FMS recall experiencing a wider variety of symptoms in childhood than women without FMS. This may mean that an excess of childhood illness or certain symptoms are risk factors for the development of FMS later in life. Prospective studies in children may help determine which individuals are more susceptible to developing fibromyalgia.
