[Effect of health education of schistosomiasis control with Yi-Han bilingualism].

OBJECTIVE: To evaluate the intervention effect of Yi-Han bilingual health education of schistosomiasis control. METHODS: Baimiao Village in Daqing Town, Xichang City, where Yi Nationality inhabited, was chosen as a pilot to carry out Yi-Han bilingual health education of schistosomiasis control from 2012 to 2015. The villagers and students in the pilot area were investigated by questionnaires before and after the intervention to understand their awareness and correct behavior status on schistosomiasis control. RESULTS: After the intervention of Yi-Han bilingual health education of schistosomiasis control for 3 years, the awareness rate and the correct rate of behavior on schistosomiasis control of the villagers in the pilot area improved from 45.79% and 51.12% in 2012 to 97.80% and 98.78% in 2015. As for the students, the two rates mentioned above improved from 64.16% and 60.83% in 2012 to 100% and 98.89% in 2015 respectively, and all the differences between the rates before and after the intervention were statistically significant (all P < 0.01). CONCLUSIONS: The intervention of Yi-Han bilingual health education of schistosomiasis control can obviously improve the knowledge awareness rates and the correct rates of behavior of the residents and students in the gathering area of Yi Nationality.

Study on the relationship between hepatitis C virus infection and sharing injection equipment, sexual behavior among injecting drug users / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study hepatitis C virus (HCV) transmission through different modes of sharing injection equipment and sexual behavior among injecting drug users (IDUs) in Liangshan of Sichuan province.</p><p><b>METHODS</b>A community-based survey was conducted to investigate past and current demographic data, injection equipment sharing patterns and sexual behavior of IDUs. Blood samples were also taken to test for HCV. The survey was conducted between Nov 8 and Nov 29, 2002. 379 subjects were screened through outreach recruitment and peer informing. SPSS (11.5) was used for data analysis.</p><p><b>RESULTS</b>HCV prevalence was 71.0% (269/379). Needles or syringes sharing in the past three months and past syphilis infection were strongly associated with HCV transmission after univariate analysis using chi-square test. Trend analysis indicated that HCV infection rate increased along with the increase of needles or syringes sharing, sharing of rinse water and the number of peers sharing the equipments. Data from multivariate logistic regression showed that sharing of needles or syringes and history of syphilis infection were significantly associated with HCV transmission. No significant difference was found between HCV infection and sexual behavior after univariate analysis using chi-square test.</p><p><b>CONCLUSION</b>Further sero-epidemiological prospective cohort studies should be conducted to clarify the relationship between different modes of sharing injection equipment, sexual behavior and HCV infection.</p>
