An attempt was made to make use of the results of a kind of health questionnaire in health administration or evaluation of health status of both a group of people and specific individuals.The Todai Health Index, THI, was developed by S. Aoki et al. in 1974 with the purpose of supplementing the widely-used Cornell Medical Index, CMI. It consists of 130 questions. Twelve scales and three discriminant scores are available for use in evaluation.In this paper, quantitative and qualitative differences of subjective complaints in five sex-age groups, and the relevance and usefulness of the THI in this problem were investigated.The survey was carried out using 5, 937 employees of a trading company. The five sex-age groups were as follows; females in their twenties (2, 190), males in their twenties (1, 217), males in their thirties (948), males in their forties (592) and males in their fifties (479).To determine quantitative differences, the proportion of responses to each question, the mean value of scale scores and discriminant scores were used. To determine qualitative differences, the factor-pattern of subjective complaints and scale scores were each checked by factor analysis.The results were as follows:1) Females in their twenties had many physical and psychological complaints, especially concerning their eyes. Two subjective complaint factors, the control of temper and the depression, were extracted by factor analysis. Twelve scales were divided into a physical scale group and two psychological scale groups.2) Males in their twenties had three factors; an irregular lifestyle, the complaints of the digestive organs and the self-aggrandizement.3) Males in their thirties seemed most stable, both physically and psychologically of the five groups.4) Males in their forties showed depression. This was assumed to be a result of a loss of self-confidence in their physical condition or their work ability.5) Males in their fifties had regular lives and were psychologically stable. On the other hand, this group showed somehow neurotic conditions and high scores on the “living scale”. Two factors, related to cardiovascular complaints and the self-aggrandizement, were extracted by factor analysis of subjective complaints.The author believes that these results have determined relevance of the THI in collecting information about the physical and psychological status of both groups and individual people.
