OBJECTIVE: To study the clinical and radiological prevalence of skeletal fluorosis among the retired employees of Wonji-Shoa sugar estate.
DESIGN: Retrospective and cross-sectional study.
SETTING: Wonji-Shoa sugar estate, an agro-industrial estate located in the Ethiopian Rift Valley.
SUBJECTS: Two hundred and sixty three employees of the estate who retired between 1995 and 1996.
MAIN OUTCOME MEASURES: Clinical evidence of impaired squatting, neck and lumbar mobility, kyphosis, and X-ray evidence of fluorosis.
RESULTS: Skeletal fluorosis was more evident among the males (p<0.05), and the prevalence was higher among the factory and the agricultural workers than among the administrative workers (p<0.05). Clinical prevalence was 20% versus the radiological prevalence of 70.3%, indicating that many cases were asymptomatic. Impaired neck and lumbar mobility and impaired squatting significantly agreed with the radiological diagnosis (p<0.05) while kyphosis was not.
CONCLUSION: Further clinical and epidemiological studies are suggested and strengthening of the existing defluoridation programmes within the area is recommended.
