ABSTRACT
Objective To understand the current situation of soil-transmitted nematode infections and influencing factors of pupils in rural areas of Yi Ethnicity in Butuo County, Sichuan Province, so as to provide the evidence for the prevention and control of soil-transmitted nematode infections. Methods In 2016, the pupils of 2 villages in Butuo County were selected by the multi-stage random sampling method, and the relevant information was obtained by questionnaires, including social demographic information, diet and hygiene habits and acknowledge of parasitic disease prevention. The soil-transmitted nematode infections were examined by Kato-Katz technique. The results were statistically analyzed by the single factor analysis and multivariate logistic regression methods. Results A total of 160 pupils were investigated in this survey. The soil-transmitted nematodes included Ascaris lumbricoides, Trichuris trichiura and hookworm. The overall infection rate was 89.38%, and the multi-infection rate was 54.55%. The infection rates of A. lumbricoides and T. trichiura were higher. The infection densities were mild (75.68%) or moderate (22.97%). The logistic regression analysis showed that the protective factor of soil-transmitted nematode infections was the knowledge about correct diet and health habits notified by teachers (OR = 0.67), but the risk factor was drinking unboiled water (OR = 19.26). Conclusions The infection rate of nematodes is still high in the pupils in rural areas of Yi Ethnicity in Butuo County, Sichuan Province. Therefore, we should strengthen the prevention and control of soil-transmitted nematode infections, especially A. lumbricoides and T. trichiura infections, and mostly develop the teachers’function in health education.

ABSTRACT
Objective To explore the acceptability of male circumcision (MC) as an HIV prevention method and its related factors among young men of Yi ethnicity in Liangshan prefecture. Methods 446 young men were selected in Butuo county,under stratified sampling method. Using a self-designed questionnaire,face to face interviews were taken to collect HIV-related risk behaviors,knowledge and acceptability of MC. Results After an introduction on MC by interviewers,40.6% of the interviewees expressed their willingness in taking this surgery. The main reason for acceptance was that they felt this surgery might reduce the risk of HIV infection (90.1%). For those who refused to take this surgery,most of them thought it was too sensitive and embarrassing (52.5%) and were afraid that it might affect their procreation ability. Data from logistic regression analysis indicated that the acceptability of MC was associated with the following factors as: age,income,experience of commercial sexual behavior. They also felt that messages related to male MC surgery could reduce the risk of being infected with HIV/STDs or induce pain when having sexual intercourse,or it might cause partial infection after surgery,or they might be mocked at if taking the surgery. Conclusion It is the prerequisite in helping young people of Yi ethnicity to have a good understanding on MC as for Yi people,embarrassment attitudes towards sex appears to be one of the big obstacles against the popularization of this surgery. The operation should be provided by trained and professional doctors,with standardized procedure,in good sanitary conditions and free for service.
