Blood pressure in a high school population. II. Clinical profile of the juvenile hypertensive.

One-hundred-fourteen hypertensive high school students were evaluated to determine whether a distinctive clinical profile could be identified; 71 normotensive students served as controls. Selected blood chemistry determinations, urinalysis, and chest roentgenograms were done to help rule out secondary causes of hypertension. Left ventricular function was assessed by echocardiography and systolic time intervals. The hemodynamic response to exercise was also evaluated. A significant number of the subjects 14 to 18 years of age with persistent systolic and/or diastolic pressure 1.65 SD above the mean for age and sex showed the following: obesity; elevated serum triglyceride concentration; basilar hypertrophy by electrocardiogram/vectorcardiogram; electromechanical systole and pre-ejection period shorter, and the ratio of the pre-ejection period over the left ventricular ejection time lower, than mean for age and sex as determined by systolic time intervals; volume indices depressed and cardiac contractile functions elevated as determined by echocardiography; higher blood pressure at start of exercise stress test and higher peak systolic and diastolic pressures during test, and a slower return of heart rate to base line level after the test. The above findings should be useful in following the course of a young individual with essential hypertension and may provide a means of evaluating therapeutic intervention.

Blood pressure in a high school population. I. Standards for blood pressure and the relation of age, sex, weight, height, and race to blood pressure in children 14 to 18 years of age.

This is a report on the initial from an ongoing study of blood pressure in ninth to twelfth grade students in the St. Louis metropolitan area. The purpose was to establish standards, to determine the incidence of hypertension, and to examine the relationship of blood pressure to age, weight, height, sex, and race. Subjects with persistent hypertension were to be investigated and checked annually as long as they were in high school. Students in the ninth grade at the beginning of the project were to be screened each year for four years.

High blood pressure in children: problems and guidelines for evaluation and treatment.

Evidence is presented from studies of the authors and of other investigators that primary hypertension is more common in children than was previously thought. Ninety-five percent of 131 asymptomatic children with incidental hypertension were considered to have primary hypertension after investigation for possible causes. The definition of hypertension was based on normal ranges of blood pressure for each age and sex. However, the definition of juvenile hypertension is still unsettled as is the question of treatment. Investigation of the effect of prolonged antihypertensive therapy on growth and development is needed. Primary hypertension in the young makes possible the study of the disease at its inception.

Blood pressure and puberty.

The purpose of this investigation was to study the relation of blood pressure to sexual maturation in 229 boys and 189 girls, 10 to 14 years of age. The results showed that there was no significant correlation between the systolic and diastolic pressure with the level of serum follicle-stimulating hormone and luteinizing hormone in either sex. Nor was there a significant correlation with the stage of pubic hair development in the boys nor with the stage of breast development, menarche, and duration since menarche in the girls. Therefore the presence of hypertension during 10 to 14 years of age should not be regarded as a physiologic response to pubertal development, but rather as a suspicious finding which deserves careful follow-up examinations.
