ABSTRACT
A cross-sectional case-control study on the association between the reduced work ability and S. japonicum infection was carried out in a moderate endemic area for schistosomiasis japonica in the southern part of Dongting lake in China. A total of 120 cases with reduced work ability and 240 controls paired to the case by age, sex, occupation and without reduced work ability, participated in the study. The mean age for individuals was 37.6 years old (21-60), the ratio of malefemale was 6040, the prevalence of S. japonicum in the individuals was 28.3. The results obtained in this study showed that the infection of S. japonicum in case and control groups was 49.2 (59/120) and 17.9 (43/240), respectively. Odds ratio for reduced work ability among those who had schistosomiasis was 4.34 (95), confidence interval was 2.58-7.34, and among those who had S. japonicum infection (egg per gram > 100) was up to 12.67 (95), confidence interval was 3.64-46.39. After odds ratio was adjusted by multiple logistic regression, it was confirmed that heavier intensity of S. japonicum infection and splenomegaly due to S. japonicum infection were the main risk factors for reduced work ability in the population studied.
