In 1989, parents and teachers of young people with mental handicaps in Stockholm (41 parents and 20 teachers) and Tokyo (106 parents and 111 teachers) were given a questionnaire about their praxes of and attitudes towards health and sex education. Results from the study indicated that, compared to parents and teachers in Tokyo, parents and teachers in Stockholm gave more information about health and sex to their 15-16-year-old young people with mental handicaps. This was especially so regarding information about HIV/AIDS. More parents and teachers in Stockholm also had positive attitudes towards sex and interpersonal relationships -not only for young people in general but also for young people with mental handicaps -compared to parents and teachers in Tokyo. Some questions of an ethical nature were found difficult to answer in both Stockholm and Tokyo.
