Serum cholesterol (TC) and triglycerides (TG) levels were measured in residents (aged 20-69 years), of Kumamoto Prefecture, Japan, at health screenings in 1983-1985. Results were compared with those obtained in the same area in 1973-1976.
TC showed a significant increase of 6-12mg/dl in 35-39 and 45-49-year-old males, and in 25-44-year-old females. TG showed a significant decrease of 9-25mg/dl in 35-44-year-old males, and in 45-69-year-old females.
A nutritional study was conducted, which showed that intake of protein, fat, and animal fat had increased. This result agrees with the annual changes reported in daily per capita nutritional intake of the Japanese.
Although the life-style and particularly the diet of the Japanese have been changing rapidly, there has been relatively little change in TC levels. This fact may help to explain why the mortality rate for cardiac disease in Japan is still one of the lowest among the developed nations.
