We are not aware of previous epidemiological studies of the prevalence and risk factors of DRS in Tunisia or other Arab countries, and few studies have addressed these issues elsewhere. OBJECTIVES: To determine the prevalence and incidence of DRS in Monastir, Tunisia; to look for risk factors; and to evaluate socioeconomic costs. METHODS: Data on a cross-section of 5000 individuals aged 15 years or older living in Monastir were collected by interviewers using a previously developed 51-item questionnaire. RESULTS: The study participation rate was 87.6%. The annual prevalence of DRS was 2.21% and the incidence was 1.44%. Among the patients with DRS, 94.8% received healthcare interventions, 64% had plain radiographs taken, and 45.4% underwent computed tomography of the lumbar spine. Sick leaves were given to 77.7% of patients, and mean sick leave duration was 9 weeks. A change in job was required in 5.5% of cases. Factors associated with DRS included male gender (P<0.001), obesity (P<0.0001), smoking (P<0.0001), a history of low back problems (P<0.0001), anxiety and depression (P<0.0001), a job requiring prolonged standing and bending forward (P<0.03), heavy manual labor (P<0.005), heavy lifting (P<0.0001), and exposure to vibrations (P<0.0001). CONCLUSION: The prevalence of DRS in Monastir is 2.2%. We identified a number of patient- and occupation-related risk factors. The high socioeconomic cost should encourage preventive measures.
