Abstract

Data from 10,559 men and women, aged 30-64, participating in the morning and afternoon in a Chicago Health Department multiphasic screening project, were used to evaluate the relationship of time of day and time since last meal to group mean serum cholesterol, hematocrit, systolic and diastolic blood pressure, and heart rate. Serum cholesterol showed no definable differences with time of day and time since last meal. Hematocrit values tended to be slightly higher in the morning than in the afternoon and showed no consistent differences with time since last meal. Systolic blood pressure values, but not diastolic, were slightly higher in the afternoon than in the morning. Mean heart rates tended to be slightly higher in the afternoon and lower with time elapsed since last meal. All these differences were small and not of an order to present significant problems with regard to carrying out mass screening for these variables over the course of the day.
