title: [Influence factors of Schistosoma japonicum infection among fishermen in eastern Dongting Lake Region].
abstract: OBJECTIVE
  To investigate schistosome infection among the professional fishermen in Yueyang County, East Dongting Lake Region and its influence factors.
  
  
  METHODS
  A total of 275 fishermen from two fisherman villages in Yueyang County were selected in 2009. They were investigated by fecal examination and questionnairing. The stool-egg positive individuals were detected by B ultrasound. The multivariate unconditional Logistic regression analysis was used to explore the related factors of schistosome infection and liver in fishermen.
  
  
  RESULTS
  The total infection rate in fishermen was 40.4% (111/275), and the geometric mean of EPG was 17.4 +/- 4.4. B ultrasound data showed among 111 egg positive individuals, 39 (35.1%) cases manifested as hepatomegaly, 22 (19.8%) had splenomegaly, 11 (9.9%) had portal vein expansion and 65 (58.6%) had hepatic fibrosis. Multivariate unconditional Logistic regression analysis showed that age groups (OR = 0.630), fishing working years (OR = 2.470), chemotherapy frequency (OR = 0.425) and chemotherapy in 2008 (OR = 0.290) were the influence factors on schistosome infection (P < 0.01).
  
  
  CONCLUSIONS
  Schistosome infection rate is high, Schistosoma japonicum-induced liver and spleen injuries are still severe in fisherman of Eastern Dongting Lake Region.
