Abstract
Health Examination for children of three years old has been performed as one of the governmental health services in Japan and has a role of finding health problems arising at that phase of their development. However, the rate of attendance at this examination is not high particularly in urban area of big cities like Tokyo. For the purpose of detection of factors involved in this low rate of attendance, a survey was carried out on 590 children who were the objects of the examination at Nakano-Kita Health Center in Tokyo in 1966. The comparative analysis of the different conditions between the attendants and the non-attendants, revealed that there was a difficulty in getting contact with the objects because of highly frequent change of their adresses. Another reason of non-attendance was related to the thought of parents that the similar examination could be made by their home-doctors. For the solution of these difficulties it can be sussested the examination should be arranged effectively so that it would meet the real needs of the community. The participation of home-doctors to this examination program was also considered to be of foundamental importance.
