Clonorchis Sinensis Control Intervention at a Sumjin Riverside Area / 農村醫學 地域保健

ABSTRACT

OBJECTIVES: This study was performed to investigate the changes in the prevalence and its related factors of the Clonorchis sinensis(C.S.) in the inhabitants at Goksung-Gun along Sum-Jin river after C.S. control intervention. METHODS: The subjects were 416 among 699 in the 8 same villages selected by stratified cluster sampling in 1999. The formalin-esther sedimentaion technic was used for the C.S. egg detection and the questionnare for the related factors. The study was carried on from February, 2005 to March, 2005. RESULTS: The prevalence of C.S. decreased significantly from 19.0% in 1999 to 11.3% in 2005. The signicicant factors in 1999 such as sex, age, area, raw fish eating habit and drink habit were not significant statistically. On the other hand factors such as the awareness of C.S. and the health behavior were changed significantly(p=0.034, p=0.021). CONCLUSIONS: These results suggest that C.S. prevalence became lower than previous study five years ago. But its control intervention should be extened to the general population regardless of sex, age, area, raw fish eating habits, drink habit and we need to make an effort to improve the awareness and the health behavior of C.S..
