Abstract: AIM: To elucidate the relationship between schistosomiasis transmission and socioeconomic factors in Yunnan mountainous region. METHOD: A house visiting investigation with a questionaire concerning socioeconomic factors was conducted in four natural villages in Weishan and Eryuan counties, Yunnan Province in 1993. RESULTS: (1) The rate of disease history was significantly higher in women, inhabitants with lower education level, with lower income, with lower sense of individual protection and with more frequent labor exchange than in men, inhabitants with higher education level, with higher income, with higher sense of individual protection and with less frequent labor exchange; (2) the frequency of water contact with cercariae and defecation in the wild was significantly higher in cases with disease history than in those without the disease history. The results from multi logistic regression analysis suggest that labor exchange, contacting infested water, defecating in ve getable field, using water in ditches and canals for daily life and working in paddyfields were the important factors influencing the prevalence. The infected domestic animals were another risk factor. CONCLUSION: The transmission of schistosomiasis in Yunnan mountainous region are notably related to socioeconomic factors and behaviour aspects of local inhabitants.
