Epidemiological characteristics of human hydatidosis and risk factors in Habahe County, Xinjiang

Objective To analyze epidemiological characteristics and risk factors of human hydatidosis in Habahe, Xinjiang uygur autonomous region, and provide evidence for the local prevention and control of human hydatidosis. Methods The data of local people receiving screening from 2008 to 2013 were analyzed with software SPSS 17.0, and risk factors were identified through univariate and multivariate logistic regression analysis. Results A total of 42 356 residents were screened, 161 of them were diagnosed with hydatidosis (2 were diagnosed with alveolar hydatidosis), the overall prevalence of hydatidosis was 380.11/100 000. The prevalence of cystic hydatidosis was 375.39/100 000 and the prevalence of alveolar hydatidosis was 4.72/100 000. The patients aged 10 years accounted for 2.48% (4/161), the patients aged 10-20 years accounted for 9.94% (16/161). The risk of hydatidosis increased with age, which peaked at age of 40-50-years (OR =2.5325); the risk of hydatidosis in herdsmen was 2.626 times higher than that in farmers, the risk of hydatidosis in the residents who slaughtered livestock was 3.245 times higher than that in those who did not slaughter livestock; the risk of hydatidosis in the residents living in pastoral townships was 2.352 times higher than in those living in agricultural townships. Conclusion The proportion of the patients aged 10 years decreased significantly due to the comprehensive prevention and control. However, the risk of hydatidosis still exists, it is necessary to further strengthen the prevention and control of hydatidosis.
