The purpose of the present study is to examine whether or not one's life environment factors effect on his state of health. Data were gathered from those who took health examinations at a health care center during the period of June 3 to Sepetember 22, 1987. A total of 1200 males and females were surveyed. Of those only males (N=955) are singled out for detailed study. The analysis focuses upon examination of the relationship between the subjects' life habits (e.g. exercise habit, ocupation, etc.) and various health index scores obtained from clinical chek-ups of the subjects. The results include the followings: 1. Relationships were found between life habits (i.e. occupation, smoking, driving, and motorcycle riding) and various health indexes considered. 2. Greater deviation in blood sugar (at the time of starvation) was ovserved for those reqularly exercise for their health sake, whereas more of those without exercise habit tended to deviate with regard to heart-lung ratio, red blood cell count, and MCV. 3. Those who were considered working too hard showed significantly higher level of obesity and TG (triglyceride), but the number of deviants on these indexes were relatively small for them. 4. Greater deviation in cardiac funcution (i.e. RaV5) was observed for those having a concurrent job position. 5. A large proportion of heavy smokers (i.e. those who smoke more than 21 cigarettes per day) were found to be deviants regarding body type, hemogram, and blood circulation. 6. Greater deviation in cardiac function (i.e. RaV5, SV1 + RV5, and heart-lung ratio) was observed for those who drive a car and/or riding a motercycle. The above results suggest that one's life habit such as exercise, occupation, smoking, and driving have an effect on his state of health including obesity, blood pressure, heartlung ratio from X-ray photograph, RaV5 and SV1 + RV5 from electrocardiograph, blood count, and biochemical test results of blood.
