The goal of this study is to estimate the incidence of Fibromyalgia by age and sex, which has not previously been reported in the literature. Prevalence data demonstrates that 2% of the US population suffers from this disorder. Newly-diagnosed cases of Fibromyalgia were identified in 1998 to 2002 among members of the Deseret Mutual Benefits Administrators (DMBA) database. The DMBA is the nationwide health-insurance database of the Church of Jesus Christ of Latter-Day Saints (LOS) and contains data on roughly 60,000 insured parties per year. This retrospective cohort study will include incidence rates per 1,000 person-years with the DMBA membership as the denominator. We will calculate sex-specific relative risk ratios and age-specific incidence rates from 0 - 60 years. Preliminary results are an overall incidence rate of 7.6 cases/1,000 person-years. The peak incidence by age is 15.4 cases/1,000 person-years from age 50-60 years and an overall relative risk for females of 1.84.
