A total of 1, 078 records of physical examinations conducted upon the subjects' enrollment in Japan Women's College of Physical Education were investigated. The 1, 078 female student athletes were born during the period between 1953 and 1957 and entered the college between 1972 and 1975. The following results were obtained:i) Comparing the birth seasonality among three groups with different athletic ability levels, the 1st grade athletes (who had been entrants in all-Japan or international competitions) and the 2nd grade athletes (who had been entrants in Japanese prefectural competitions) were relatively less frequently born between April and July than the 3rd grade athletes (who had never been entrants in any of the above-mentioned competitions).ii) Those who were superior in athletic ability tended to have greater height, body weight and back strength and later menarche, but no significant differences in the Rohrer Index.iii) The differences by season of birth in body structure, back strength and menarcheal age were not so evident as those by athletic ability levels. However, within the 1st grade ability level, the height of those born from August to October was significantly greater, and within the 2nd grade level, significantly later menarche was seen among those born between May and July.iv) Comparing the differences in height, body weight, back strengthth and menarcheal age among the three athletic ability levels within the same season of birth, the differences by athletic ability levels tended to be larger among those born between May and July, which is the season when the fewest 1st grade athletes were born.
With the government agency's state and movement of production statistics and other such data, this study made on the transition of morbidity and mortality rate of tuberculosis will concentrated on:(1) Contemplation on assessments made mainly from analysis of regression lines of 21 countries including Japan: The mortality rate par 100, 000 population as the subordinate variable and the difference of 1900 subtracted from the calender year as the independent variable.(2) Contemplation on assessments made in uniform manner from 46 prefectures of Japan excluding Okinawa. The results are as follows:(a) In the period other than the time during the two world wars up to 1955, transition of mortality rate of each country has been found to be nearly in a straight line.(b) The regression line after 1955 has been found to be declining in relatively moderate angle than before. Therefore the regression line of each country is refracted at the point of 1955.(c) We have found the relation between the coefficient value and the constant value of every regression line plotted on an ordinary graph to be nearly in a straight line.(d) The regression line of 46 prefectures are nearly alike above results (a), (b) and (c).But these refracted points seem to be 1960.
Household interview surveys for illness behavior were conducted at Hateruma Island, that is the southern end of Okinawa, Japan, in 1977 and 1978. From home visits of 105 households in 1977 and 107 in 1978, we had obtained information on family member's morbidity and action taken for each perceived illness episode. Analysis were made on factors relating illness behavior, especially the relationship between illness behavior and the recognition of severity of perceived illness, and also the family network. The findings were summarized as follows;1. People are not satisfied with the present medical care services provided and they have unfavorable image for the levels of medical care they can use at the Island.2. Of the actions taken for their perceived illness, 58.4 per cent were professional care by physicians or medical service men; 25.5 per cent were semi-professional care using patent medicine nonprescribed; 7.4 per cent were non-professional care using home remedies and herbs; and 8.6 per cent were continued usual work and/or lay consultation.3. Significant difference of actions were observed by family composition, length of illness episode (temporary or chronic), kinds of illness, family members living outside the Island and frequency of their contact; and were also partially observed by age groups and family income. It is suggested that the recognition of the severity of the perceived illness is the most important determinant of illness behavior among factors examined, and family network is related with the professional care out of the Island.4. Actions for illness were grouped into five patterns such as use of professional care in the Island, use of professional care out of the Island, use of the outreach services provided by the regional prefectural hospital in the main island, combination of use of professional care in the Island and use of patent medicine nonprescribed, and use of patent medicine.5. Based on the findings, the author had presented a hypothetical model of illness behavior.
