Normotensive and hypertensive farmers ranging from 18 to 72 years of age in rice-producing districts of Iwate-ken were examined in winter, then both total and esterified cholesterol in serum were determined.There was an increase in the total serum cholesterol levels with age until 59 years old, and the average cholesterol levels in hypertensive patients were higher than those in the normotensive subjects indifferently from sex distinction.The levels found by us were considerably low in comparison with the data reported by Keys et al. and Adlersberg et al. in U.S.A. and were similar to those by Fidanza in Southern Italy.In the group of advanced age, the average serum cholesterol levels in female were generally higher than that in male. The esterified and total cholesterol ratio was nearly constant from 30 to 59 years of age, but slightly higher from 18 to 29 years old and lower in the older group above sixty.
