The increasing trend of visits to medical facilities by the elderly has become a recognizable social problem since 1983, as a result of the aging of population in Japan in recent years. In this paper, the regulatory factor of the visit rate, as an indicator of the health behavior, was analyzed by such methods as factor analysis and multiple regression. Major results were as follows: 1) The visit rate has the positive and significant correlation to those variables that are characteristic of urban life (convenience in traffic, etc.). On the contrary, a negative correlation is found to the variables typical of rural life, such as the ratio of owner house, etc. 2) The twelve clusters were formulated through 29 variables, and then the twelve variables were selected from each cluster, which was based on the highest correlation with the visit rate, and used for the factor analysis. 3) The result of factor analysis can be concluded as: the first factor is urban life, the second factor, a poor health status as defined by the vital statistics, and the third factor, extremely thin population density. 4) These three factors were used for the multiple regression analysis. The multiple correlation coefficient was then calculated to be 0.679, and the contribution ratio was 46.1%. Thus, the a of first factor was 0.561, the second factor, -0.327, the third factor, -0.200. In sum, it was noted that the urban lifestyle was a far more important factor associated with the increase in the visit rate, while the poor health status and the low density of population significantly contributed to the suppression of the visit rate.
To investigate the relationship between female obesity and thyroid function, serum T3 and T4 in the females who lived in Shiramine-village, Ishikawa prefecture were measured. The results obtained were as follows. 1) Significant positive correlation between obesity index and the levels of serum T3 was observed in the normotensive subjects only under 39 years old. On the other hand, there was no significant correlation between obesity index and the levels of serum T4 in the normotensive subjects under 39 or over 40 years old. These results suggest that obesity is prevented in part by the increase of serum T3 in the normotensive females under 39 years old. 2) In the subjects whose obesity index was over +10%, the levels of serum T4 in the borderline hypertensive subjects were significantly lower than those in the normotensive subjects. Therefore, it could not be demonstrated that there was positive relationship between the increase in blood pressure induced by obesity and the increase in the levels of thyroid hormon.
The consistency of answers to C.M.I.-Health Questionnaires which consist of 207 questions ranging from A to S sections was evaluated using the pairs of answers of girl students in a nursing school obtained through carrying out twice at an interval of a month, the second 207 questions being rearranged at random . The answers to the questions concerning sexual organs section were excluded for the analysis of the consistency. The results showed that the consistency of answers to the questions concerning respiratory system, cardiovascular system, digestive tract, muscles and bones, skin, nervous system, fatigue, feeling of malaj ustment, anger, tension and thinking and judgement was 22.1, 20.0, 31.8, 11.1, 12.5, 11.1, 12.5, 16.7, 25.0, 22.2, 16.7% respectively. The consistency of answers to all the 197 questions ranging from A to R sections was only 12.2%.
