A survey of physical mesurements, blood pressure, blood mesurements and frequency of food consumption was conducted on 152 males and 229 females, aged 40 to 65 years, from three rural districts in Saga prefecture. The districts were Ariake (flatland area), Kohhoku (intermediate area) and Yamanouchi (mountainous area). While, on the aged -above 70 years, a questionnaire on daily living and health condioion was investigated.
The results were summarized as follows:
1) The values of skinfold thickness differed little among the districts. The rate of obesity by skinfold thickness both in male and female was lower than the result of National Dietary Survey in 1981. However, the average skinfold thickness in females were higher a little compared with the values of our suruey in same region in 1971.
2) The prevalence rate of anemia in females was remarkably high (below 12g/dl of hemoglobin, 34%). It presumed that agricultural work load might heavy, and nutrients intake correspond to the work load was insufficient.
3) From the results of frequency of food consumption, inhabitants in Ariake compared with Kohhoku more frequently intaked modern food e. g. meat, milk. On the other hand, Kohhoku was higher in blood pressure, HDL-cholesterol/total cholesterol ratio, and lower in triglyceride, total choresterol than Ariake. We guessed that the food consumption pattern mainly affect on the results of blood pressure and serum lipids.
4) In relation to the correlation matrix which calculated on all districts, the higher the obesity, the higher the blood pressure, triglyceride, total cholesterol and cholinesterase activity, whereas the obesity decreased HDL-cholesterol and HDL-cholesterol/total cholesterol ratio.
5) Among 90 persons aged above 70 years, the rate of ones who can not work from physically disability, and who have any desease was 18%, 51% respectively.
