　View Summary

Of the three countries, health education was included in the curriculum in the Philippines and was not included in Kenya and Niger. On the other hand, religious education was not included in the Philippines but was included in Kenya and Niger. Textbooks on language, science, social studies, religion, etc. included health topics and it was suggested that integration into general subjects was implemented smoothly. Topics included are hygiene education, diseases and injuries, nutrition, safety, environment, disasters, social problems, etc.. The priority distribution varies from country to country, and topics reflecting the state of the country are also taken up, for example, hygiene education, drought issues in Niger, HIV / AIDS and traffic accidents in Kenya, and typhoons in the Philippines. Those were capturing issues in each country.

　View Summary

We developed a village assessment questionnaire based on the primary health care concept in two health centers' catchment areas, Xepon district, Lao PDR, with the help of Laotian experts and health center staff. A pilot study was conducted in the 10 villages, using the developed questionnaire that consists of 8 domains with 42 items. The survey showed the following advantages of the questionnaire: First, the questionnaire helped to identify potential risk factors for common health problems. Second, it was sensitive enough to capture differences in risk factors among villages. Finally, a survey using the questionnaire could be implemented by health center staff without special financial input or training.

The Mastery Approach to Coaching (MAC) is coaching-education program that showed a significant effect on youngsters' self-esteem. We tested an intervention with sports activity using MAC to enhance young students' self-esteem in Leyte, the Philippines. The Rosenberg's self-esteem questionnaire was translated in local language. We included all 10th grade students (n=744) in four schools, Two schools wereMAC intervention and the others were the control group. All schools were encouraged to involve students into volleyball activity during January and February 2015. In January 2015, MAC workshop was held in the intervention schools. Of total, 524 students completed the questionnaires. However, students' involvement was poor in an intervention school. We excluded this school from the analysis, The remaining intervention school showed a significant change in self-esteem, which average score raised from 20.3 to 21.2 (P=0.01). The control group didn't showed significant improvement.

n Evaluation of Innovative School Health and Nutrition Education through Field Experiments - An Enquiry into the Sustainable Health Improvement of Poor Children in Developing Countries

　View Summary

The field experiment for this research project was implemented in collaboration with an international NGO. Twelve project staff and eighteen para-teachers were recruited and trained. In addition, over thirty survey staff were hired and trained for the baseline and the endline survey. The skills based health education was provided to 90 primary schools, once a week for twelve months. A cross-cutting soap provision intervention was also conducted. Due to the political instability and other factors, the project implementation and survey were delayed, and consequently, data organisation and exploratory analyses are still underway. The exploratory analyses show that each of the health education intervention and soap provision intervention has positive effects on some health indicators with statistical significance. Further examinations on the set hypotheses and analysis methodologies will be carried out and papers will be drafted for publication.

　View Summary

In the present study, many patients with strongyloidiasis and uninfected control subjects in Okinawa were examined for their HLA DRB1 type of leucocytes, which is the most polymorphic MHC among class II MHC,by using PCR-SSO method. The frequencies of DRB1 1501,1503,0409 and 0802 were relatively high in uninfected control subjects, while in strongyloidiasis patients, DRB1 1503 and 1501 alleles were frequently detected. When the frequencies were compared for each type of DRB1 between the patients and control subjects, the typ of 1501,0490,0802 and 1406 were highly detected in control subject and those of 1503,0302,0404,1302 and 1406 were frequent among the patients. The difference in frequency, however, was not statistically significant between the control and patient groups, showing that there was on relation between Strongyloides infection and HLA DRB1 type of patients' leucocytes. The intensity of infection estimated by number of larvae excreted in feces and anti-Strongyloides antibody levels estimated by ELISA were also on relation with the type of HLA DRB1. On the other hand, It has been well known in Okinawa that many strongyloidiasis patients have concurrent infection with human T-lymphotropic virus type-1(HTLV-1). The effect of HTLV-1 infection the efficacy of treatment of strongyloidiasis and anti-Strongyloides IgE antibody response were furher examined, in relation with their HLA type. As the reults, it was confirmed that the efficacy of treatment and serum level of IgE antibody to Strongyloides were significantly low in the patients with concurrent HTLV-1 infection. The HLA DRB1 types, however, also showed on relation to the therapeutic effect and IgE antibody response, indicating that the main cause of long-term persistence of Strongyloides infection among Okinawa inhabitants were considered to be high concurrency with HTLV-1 infection rather than genetic background of the inhabitants.
