To investigate whether exercise is beneficial for prevention against aging or not, serum lipoperoxide, considered to promote aging, was measured in male students before and after taking part in a traning camp of Kendo (including 4 km running a day). The results obtained were as follows. 1) The distance which the students could run in 12 minutes after the training camp was significantly longer than that before the training camp. 2) Serum lipoperoxide levels in the students soon after the trainng camp were significantly lower than those before the training camp. However, there were no significant differences in serum lipoperoxide levels between before and 1 month after the training camp. 3) Serum total cholesterol, β-lipoprotein, HDL-cholesterol, trigliceride and uric acid levels in the students did not change significantly following the taming camp of Kendo. From these results, it can be considered that the training camp of Kendo in this study was beneficial not only for promotion of stamina but also for prevention against aging.
In order to know the interaction of physical symptom and psychological health of daughter-in-law and those of mother-in-law living together in the same household, an attempt was made to apply a self-administered health questionnaire, the Todai Health Index (THI), to 36 daughters-in-law, who have twenty to twenty five-year-old daughters, and the paired mothers-in-law. Two female control groups were sampled of the same generation of mother-in-law (control A) and daughter-in-law (control B), who live in the suburbs of three big cities. Twelve scales and two discriminant function values (DF values) of THI are as follows: SUSY, subjective symptoms; RESP, respiratory; EYSK, eye and skin; MOUT, mouth and anus; DICE, digestion; IMPU, impulsiveness; LISC, lie; MENT, mental instability; DEPR, depression; AGGR, aggressiveness; NERV, nervousness; LIFE, irregularity of life; PSD, psychosomatic; NEURO, neurosis. The mean scores of SUSY, RESP, EYSK, DEPR, PSD and NEURO of daughter-in-law are significantly lower than those of mother-in-law, which are mainly on the decrease of those in daughter-in-law, and AGGR of daughter-in-law is significantly higher than that of mother-in-law. There are significant correlations of IMPU, DEPR, NERV, PSD and NEURO, which are on the psychological scales, between daughter-in-law and mother-inlaw. While there are no significant correlations of twelve scales and two DF values between control A and B. For daughter-in-law and mother-in-law, living together in the same household for a few decades gives a better influence on the health of the both.
The rate of taking community health examinations has been steadily increasing. In 1985 it reached to 25.5 percent. This, however, is still considered to be a low figure. The present study addresses this issue of low reception rate of community health examinations. The purpose of the study is to indicate factors associated with the low reception rate of community health examinations. A questionnaire survey was conducted in a community of approximately 6, 000 population in Kumamoto Prefecture.Questionnaires were sent to the objects who were those not undergoing the community health examinations during past 4 years, asking them about their reasons for not taking the examinations. The findings include: 1) There were 559 males and 547 females who had not taken examinations; 2) Approximately 7 percent of non-recepients were away from home or missing; 3) There were 9 reasons cited for not taking exams. Reasons such as "Had checkups at workplace", "Receiving medical check-ups or care from hospitals or other institutions", "Receiving treatment for high blood pressure, heart desease, etc." represent 67 percent of these reasons; 4) There were sex differences in some of these reasons; 5) Some of relationships between reasons for not taking exams and intending to take exames in near future were understandable, while some were not quite; 6) A combination between the reason "Have confidence in health" and the intention of "Hope so that take community exams" was observed in relation to marital status. The study indicates there are two kinds of factors affecting the low reception rate of community health examinations. One is the examinational institution, and the other is associated with the inhabitants themselves. Through this study, the following were obtained: The objects of community health examinations were needed to be clearly difined, selected and reconsidered the way of calculating the reception rate by institution. As for community inhabitants themselves it appears that their medical conditions may have significant influence on their low rate of examinations.
Prevalence of subjective complaints by age was surveyed of 3389 adult women applied by a general health questionnaire-the Todai Health Index (THI). The women were sampled from the residents in the area around the Haneda, Osaka, and Fukuoka Airports excepted the noisy area of WECPNL being 90 or over. The recovery rate of the mail survey was 52%. Out of the recovered, 85.4% were married. All the subject were classified into 11 age groups at every five years of age. The positive response rate to each question, the mean values of 12 scale scores, and 3 discriminant values were compared among the age groups. And these data were also compared with male employee groups of a trading company and old gentlemen by the present coauthors. The results were as follows: 1) Women had higher scores in the scales and discriminant functions than men; Vague Complaints, Eye and Skin, Mouth and Anus, Psychosomatic disease, and Neurosis. 2) Women in their late twenties had lower scores in the scales; Vague Complaints, Respiratory Complaints, Eye and Skin, Mental Instabilty, Depressiveness, Psychosomatic disease, and Neurosis. These were different from those of men. 3) Women between their late forties and early fifties had highest scores in the same scales and seemed most unstable, which could be related with the climacteric and/or empty nest syndrome. 4) Women in their early seventies showed lower scale scores in most scales, which might be a result of the decreased sensitivity to the environmental stimuli. 5) The scale scores of Respiratory Complaints and the Lie increased according to the age, in contrast to the scale scores of Impulsiveness and Irregularity of Daily Life which decreased with aging. 6) For the middle aged women the scale scores of Aggressiveness were on the increase, but on the decrease for men. These results of a cross-sectional survery tells that the changes of THI scale scores by age could throw light on the characteristics of turning points of female life cycle.
日本の周産期死亡は諸外国に比べ,特に後期死産率が早期新生児死亡率よりもかなり高い.早期新生児死亡と数えるべき死亡を後期死産に数えると,乳児死亡率に影響を与える.そこで,1987年のWHO発行の統計年報(World Health Statistics Annual)に記載された47力国の後期死産数,早期新生児死亡数,出生数,乳児死亡数を用い,後期死産数と早期新生児死亡数の比率を諸外国のデータの平均値と仮定したときに,日本のほか諸外国の乳児死亡率がどのように変化するか計算した.その結果,早期新生児死亡を後期死産に数えるようなバイアスのかかる国と,逆に後期死産を早期新生児死亡に数えるバイアスのかかる国が存在することがうかがわれた.乳児死亡率を健康指標として,国際比較をする場合には,本研究で示した方法で乳児死亡率を訂正後,主成分分析によって総合的な評価を行なったほうがよいと思われる.
