Ethnic differences in blood pressure and heart rate of Chicago school children.

In 1975-1978, the Chicago Department of Health conducted a screening program that included measurements of blood pressure, heart rate, height, weight, triceps skinfold thickness, and arm circumference, and calculation of body mass index and muscle circumference for non-public school children. Based on data on 4,086 boys and girls aged 5-10 years from the program, this study examined the ethnic differences in blood pressure and heart rate among children of white, black, Latino, and Oriental ethnicity. Mean levels for both systolic and diastolic blood pressure were higher for Oriental and black children than for white and Latino children. These differences were independent of age, height, weight, and skinfold thickness. The black children had a much lower mean heart rate than the other children. A seasonal variation was observed for systolic blood pressure, i.e., with each sex group, the mean systolic blood pressure adjusted for age, skinfold thickness, and height tended to be higher in spring than in fall and winter. (Note-- no child was screened during the summer because of summer break.) With control for season, ethnic differences in systolic blood pressure disappeared, but not the ethnic differences in diastolic blood pressure and heart rate.

Fat-modified menu's ongoing success noted.

In 1972, a hospital food service introduced a fat-modified selective cycle menu program for its patients, staff members, and visitors. Goals and implementation are discussed.

The association between urinary sodium excretion and blood pressure in children.

This study explored the association between sodium excretion and blood pressure (BP). A new method was used to minimize the measurement error introduced by the large intrinsic variability of 24-hour sodium excretion. The ratio of intra- to interindividual variation was used to estimate the number of measurements needed to characterize the individual. When seven consecutive 24-hour samples were collected from 73 children, ages 11-14 years, a significant correlation between mean individual sodium excretion and BP was demonstrated. The independent relationship persisted when controlling for height, weight, pulse, age, sex and race (p = 0.045), but was eliminated by simultaneously considering mean creatinine excretion. Although the cross-sectional association described is quantitatively weak, a linear relationship between BP and sodium over the range consumed in this society could be important for prevention.
