[Fibromyalgia prevalence in Tunisia].
La Tunisie Médicale 2008 September
OBJECTIVE: to estimate fibromyalgia (FM) prevalence in Tunisia.
METHODS: Data on a cross-section of 1000 individuals aged 15 years or older living in Sfax were collected by interviewers using the London Fibromyalgia Epidemiology Study Screening Questionnaire (LFES- SQ). The sampling was realized by empirical poll and respecting quota according to delegation, rural or urban environment, sex and age according to the demographic national data. The positive screened subjects were invited to be examined to confirm or exclude the FM by applying the 1999 ACR criteria. The questionnaire was administered to a second group of 252 volunteers, all were afterward examined. This allowed to study specificity and sensibility of the questionnaire and allowed to calculate the FM prevalence.
RESULTS: 159 subjects were screened positive, only 141 were examined. The specialized exam allowed confirming the diagnosis of FM in 67 subjects. FM prevalence is different according to sex, age, study level and socio-economic level. Two hundred and fifty two volunteers answered the questionnaire then all examined. The questionnaire specificity was 90.8% and the sensibility 79.4%. FM prevalence in Tunisia, calculated by Bayes theorem, is estimated between 8.27% and 12.3%.
CONCLUSION: FM prevalence in Tunisia is estimated at least at 8.27%.
