Due to remarkable advances in genetic technology, it has now become possible for individuals to know their genetic susceptibility to hereditary diseases such as colon cancer. However, little is known about the awareness of public toward genetic testing. This research aimed to study the awareness of genetic testing for hereditary cancer susceptibility and the factors that might affect such awareness among adults aged 20 and over in Japan. A cross-sectional survey using self-administered questionnaire (28 items) was conducted from November 2001 through July 2002. A random sample of 400 adults aged 20 and over, living in Setagaya-ku, Tokyo, Japan, participated in this survey. Statistical analysis X2 test, t-test, Wilcoxon's rank sum test were used. The response proportion was 52.9% (n=203). The average age (years) of respondents were 47.9±17.2 (average±SD) for male, and 45.3±15.9 for female. There were significant differences between worrying about confidentiality and impression of hereditary cancer (p<0.01), and between worrying about confidentiality and existence of an examination for cancer (p<0.001). Awareness of the subjects for genetic testing included less consideration rather than know ing the word. The respondents also showed worrying about confidentiality. As genetic testing is predicted to be more frequent in the future, the merit of genetic testing is necessary to be dis cussed further.
The purpose of the study was to clarify the proportion of elderly people who aged success fully according to sex, age, and living arrangement and the factors associated with successful aging. In Nakijin Village, Okinawa, 955 elderly people aged 65 years and over were interviewed in 2001. Seven hundred and thirty (76.4%) responded to the survey. Two hundred and thirteen did not respond to the survey because of admission to hospital or institution (99), dementia (15), long absence (10), or refused to be interviewed (58), etc. Those who were completely independent on locomotion and good in self -rated health were defined as successful aging. By our definition, 68.9% of men and 64.2% of women were judged to have successfully aged. The percentage of elderly people judged as aged successfully was the highest in the people liv ing with child and grandchild for men and in the people living alone for women. The examination of factors concerning the successful aging was carried out using the logis tic regression analysis. Low level of depression, high level of social activities, grater satisfaction with life, and no history of hospitalization in the preceding year had a significant relationship to successful aging.
We examined the change in awareness, both systematically and continuously, after deliver ing education regarding acquired immunodeficiency syndrome (AIDS) by lecture mode. The sur vey subjects were 51 (school A), 49 (school B) and 45 (school C) students who entered one of the three dental hygienist schools in April 1999 and who participated in an investigation on their at titude, behavior and knowledge regarding AIDS in April and February of their first year. We conducted four lectures about AIDS after the first survey at schools A and B (Lecture group). The following results were demonstrated: 1. In the lecture group and non-lecture group, the students differed in their attitude and behavior, and the number of students who recognized AIDS as a common disease increased. 2. By receiving the lecture, students became afraid of the prevalence of AIDS; they considered that they might conduct dental procedures when they had been infected with HIV; and they believed that it was necessary for them to know whether patients were infected with HIV. 3. The students' knowledge about AIDS increased after education. It is necessary to conduct follow-up studies to examine whether the students are able to retain a good command of this education.
