Risk factors of Schistosoma japonicum infection in Xingzi County

Abstract

To explore the risk factors of Schistosoma japonicum infection in the residents in Xingzi County, Jiangxi Province. Six administrative villages from different areas were randomly selected by the cluster sampling method as the study sites in Xingzi Country in 2013, and all the residents aged 5 years or above were investigated epidemiologically, and the schistosome infection was surveyed by Kato-Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi-square test analysis and multivariate Logistic regression model. In 2013, there were 2 050 residents received the stool examination and 146 persons were positive, the schistosome infection rate was 7.1%. The Chi-square test showed that gender, age, occupation and education level were associated with the population infection rate (χ2 = 26.485、16.836、25.700、 90.805, all P < 0.05). The multivariate Logistic regression mode showed that the probability of schistosomiasis for the male was 3.041 times as much as that for the female; the probability of schistosomiasis for the illiteracy and primary education level crowd was 8.870 times as much as that for the college degree or above crowed; the probability of schistosomiasis for the junior middle school education level crowd was 5.598 times as much as that for the college degree or above crowed; the probability of schistosomiasis for the high school education level crowd was 2.995 times as much as that for the college degree or above crowed; the probability of infection of fishermen was the highest, which was 3.053 times as much as that for the other professional crowds. The risk factors of schistosome infection mainly include gender, occupation and the education level. We should strengthen the health education of schistosomiasis control, protection against the infested water contact, and so on.
