[Risk factors of schistosomiasis transmission in marshland and lake regions in midstream of Yangtze River].

OBJECTIVE

To study the risk factors of schistosomiasis related to household economic condition and individual behavior in marshland and lake regions, so as to provide evidences for schistosomiasis control.

METHODS

Six villages were sampled with the stratified cluster sampling method, 2 339 villagers from 1 247 households were surveyed by a questionnaire and meanwhile their sera were assayed for schistosomiasis by IHA. The Logistic regression was used to analyze the relationship between the results of serological examinations and risk factors.

RESULTS

The Logistic regression model fitted well (R2 = 0.598 4) and it indicated that there existed a regressive relationship between the antibody positive rate and the endemic situation of village, family economic status, age, education level and infection history of schistosomiasis.

CONCLUSION

Suitable measures should be made in according to the local economic situation, endemic type and population to control the transmission of schistosomiasis effectively.
