Higher systolic blood pressures were found among similar age groups measured in 1962 compared to those found in 1950 in the Los Angeles Heart Study. Analyses were performed to insure that these differences were real and not due to measurement differences or to self selection. Covariance analyses indicated that higher blood pressures occurred among subjects who reported that they had not eaten for 2 hr or more or for 5 hr or more prior to examination as well as among non-smokers, alcohol users, and non-salt adders. The magnitude of the differences associated with these factors is probably not of clinical significance. None of these factors explain the existing differences in blood pressures between these two examination periods. Thus, the differences observed are consistent with the hypothesis of a healthier population, age for age, entering the study in 1950 compared to the survivors examined in 1962.
