[Challenges and strategies of health education and health promotion in stage of schistosomiasis elimination].

Health education and health promotion are important measures for comprehensive control of schistosomiasis in China, which can improve the compliance rate of residents involved in schistosomiasis control activities, reduce the water contact behavior of the target population, thus avoiding or decreasing the infection of schistosome in endemic areas. In recent years, the comprehensive control of schistosomiasis in China has achieved remarkable results. China has reached the goal of transmission control and is moving toward the transmission interruption or even elimination of schistosomiasis.

[Current status of schistosomiasis control knowledge and effect of interventions among primary school pupils in Anyi County].

Objective: To understand the status of schistosomiasis control knowledge and the effect of interventions among primary school pupils in the areas of schistosomiasis transmission interrupted.

Methods: Six kinds of information materials about schistosomiasis control, including the schistosomiasis health education teaching material, schistosomiasis health education box, schistosomiasis health education stationary kits, schistosomiasis health education ball-point pen, collections of wall charts about schistosomiasis control and schistosomiasis health education curriculum schedule, were used to spread the schistosomiasis control information in the experimental group, and then, the effect was evaluated.

Results: The awareness rates, correct rates of attitude, and persuasion rates of schistosomiasis control had no significant difference between the experimental group and control group before the intervention (P > 0.

[Influencing factors of changes of Oncomelania snail densities in Poyang Lake region, Nanchang City, 2011].

Objective: To explore the influencing factors of the significant decrease of snail densities in Poyang Lake region, Nanchang City, 2011.

Methods: According to the elevation of the environment, 5 grasslands where there were high snail densities and their elevations were from 14 to 17 m were selected as study areas. The data of snails in the past three years and the hydrological information in the past five years were collected and analyzed.

[Study on an intervention model of "schools without infected students with schistosoma japonica" in heavy endemic areas].

Objective: To study an intervention model of "schools without infected students with schistosoma japonica", to control and prevent students from schistosoma infection.

Methods: Twelve primary schools of four heavy endemic counties (districts) with schistosomiasis in the Poyang Lake areas were selected as the study fields, of which, ten schools were the experimental groups, and the other two schools were the control groups by cluster random sampling. All enrolment students were the target population.

[Establishment and application of school-based health promotion and intervention model of schistosomiasis in lake-type endemic area].

Objective: To establish an intervention model of school health promotion, and apply it in developing "schistosomiasis-free schools".

Methods: At the pilot stage, all students of Henghu primary school and Banshan primary school in Xinjian County of Jiangxi Province were selected as experiment group and control group, respectively. A baseline survey covered knowledge and attitude on schistosomiasis control, water contact behaviors and Schistosoma japonicum infection rate.

The role of health education and health promotion in the control of schistosomiasis: experiences from a 12-year intervention study in the Poyang Lake area.

The objectives of this study were to examine the short-term effects of health education and health promotion in the control of schistosomiasis, and to monitor the long-term impact on re-infection patterns. The study was carried out in six Schistosoma japonicum-endemic villages located in the Poyang Lake area. Three different interventions were implemented, namely (i) health education by means of video tapes, training in prevention of infection, and a 'rewards/punishment' programme for schoolchildren, (ii) promotion of an understanding of schistosomiasis and its control plus training in prevention of infection for women, and (iii) encouragement of compliance with regard to chemotherapy plus training in prevention of infection for men.

Optimal combined approaches of field intervention for schistosomiasis control in China.

Before the mid 1980s, the emphasis in schistosomiasis control in China was on transmission control. Thus, the aim was to eliminate the intermediate host snail by environmental management, combined with chemotherapy, water supply and sanitation, and hygiene improvement. During the last 20 years, however, control approaches mainly consisting of large-scale praziquantel-based chemotherapy and health education started to be advocated and also increasingly applied.

The role of 'passive chemotherapy' plus health education for schistosomiasis control in China during maintenance and consolidation phase.

In order to explore the possibility of further optimising schistosomiasis control during the maintenance and consolidation phase in China, two highly endemic villages were selected to compare the strategy of 'passive chemotherapy' plus health education to that of mass chemotherapy singly. Emphasis was placed on treatment coverage with praziquantel among individuals infected with Schistosoma japonicum and costs incurred for treating an infected person. The results show that the former strategy was almost as good as the latter producing treatment coverage rates among egg-positives of 96.
