  • Recently, there are much concerns about ginseng as disease therapeutics. There are no epidemiologic study on relationship between ginseng intake and all cause mortality based from general population Cohort. This study sought to examine relationships between ginseng intake and all cause mortality from Kangwha Cohort data. From March 1985 through December 1999, 2696 males and 3595 females who were aged 55 or over as of 1985 were followed up. We calculate the mortality rate, standardized mortality ratio and risk ratios by ginseng intake. Cox proportional hazard model was used to adjust various confounding factors. Ginseng intake group had the lower all cause mortality(Risk ratio(RR)=0.88, 95%Confidence Interval(CI)=0.79-0.97) among males. Increasing ginseng intake, lower all cause mortality(Low ginseng intake: RR=0.88, 95%CI=0.79-0.98; high ginseng intake : RR=0.87, 95%CI=0.75-1.00) among males. There is no statistically significant difference between ginseng intake and mortality among females. The results of this study suggests that ginseng intake may prolong the human life among males.

  • To find health problems of Pohang city and to plan the activities to solve them in the situation of localization, the mortalities of the citizens in recent three years from 1994 to 1996 were analyzed from the notices and the certificates of death. The ratios of the notices with the certificates of death In the rural area of Pohang city were higher than those of whole country, the ratios of the urban area were lower than the respective ones, and the ratio differences between the rural and urban area were increasing. It may be that medical facilities are not within easy access of the rural inhabitants. especially in the rural south district with high population density. The proportional mortality indicators(PMI) were lower them those of whole country, much lower in male. So the health status of young aged males is relatively unsatisfactory. The urban inhabitants died in hospitals about two times more than the rural inhabitants and the differences were increasing. It may be that living and housing conditions and socio-cultural differences affected on the places of death. Because it is thought that death in hospitals will be growing at high speed, it is necessary to enlarge facilities fur funeral services. The age standardized mortalities were lower than those of whole country and age grouped mortalities were also the same. There were not any consistent and meaningful findings in the sex ratios of mortality according to the age groups or the calendar years. The mortalities by neoplasms and cardiovascular diseases according to the twenty one major causes of death were rapidly increased from the middle ages in both male and female. So it is important to plan the activities for early detection and health maintenance or promotion by behavior modifications. The leading causes of death were cardiovascular diseases, hypertensive diseases, and traffic accidents. And accidental drowning because of coastal area, liver diseases in male, and low respiratory tract diseases in female were the leading causes of death in part of age groups.
