[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.

Water exposure modes and times of different populations in mountainous schistosomiasis endemic areas near Qionghai lake / 中华预防医学杂志

<p><b>OBJECTIVE</b>To investigate water exposure modes and times of different populations in mountainous schistosomiasis endemic areas and to inform about the control strategies.</p><p><b>METHODS</b>All 1054 residents from populations around Qionghai Lake were randomly sampled according to occupation for a retrospective questionnaire survey in November 2001. Each individual was interviewed for his/her mode, frequency, and duration of water exposure occurring between April and October 2001.</p><p><b>RESULTS</b>The average exposure times and intensity were higher in farmers (median: 16 - 18 min/day and 2.41 - 2.5, respectively) who grow rice, tobacco, and vegetables than others (median: 3.74 - 7.39 min/day and 0.81 - 1.52, respectively); exposure frequency was found highest in farmers (median: 2.04 times/day) in all occupations; schoolchildren had low exposure frequency and times, but very high exposure intensity (median 2.34). Between April and June it is an agriculturally busy season, that is also a peak season of water exposure of adults. Schoolchildren's water exposure peaks on July and August, mainly due to playing water and swimming. Exposure times and intensities were higher in females than in males.</p><p><b>CONCLUSION</b>Water exposure modes, times, and intensities of different populations were different in mountainous schistosomiasis endemic areas of Xichang. Between April and June should be the peak infection season of adults who are engaging in agricultural activities, while July to August should be the peak infection season for schoolchildren with non-agricultural activities.</p>
