Clinical Characteristics of 18-Year-Old Men with Elevated Blood Pressure
Acta Medica Scandinavica, 2009
the Central Organization of Salaried Employees. Stochholm , S w d e n ABSTRACT. Twenty "hypertensive" 18-year-old men (systolic BP 2146 and/or diastolic BP 290 mmHg) from the screening examinations of a military draught bureau were compared with 17 normotensive (systolic BP 124-131) and 12 hypotensive (systolic BP 100-106) subjects. The hypertensive subjects were on average taller, showed more often ECG evidence of sympathoadrenomedullary overactivity, tended to excrete more adrenaline in the urine during a standardized psychological stress test, had higher serum levels of sodium and potassium and reported more frequently family prevalence of hypertension than the normotensives and hypotensives. Non-participating subjects without verified hypertension had higher mean relative weight than any of the study groups. Only one hypertensive subject showed dilated pulmonary vessels on chest X-ray and borderline evidence of mild left ventricular hypertrophy. None of the hypertensive subjects showed evidence of decreased glomerular filtration rate or endocrine disorder. The subjects in both comparison groups showed frequently ECG evidence of parasympathetic activity. The hypotensive group had a lower average relative body weight than the other groups.

Blood pressure (BP) readings in a physician's office have been reported to be higher than patient-determined readings at home. This conclusion is based on measurements in various selected groups of patients. In this study, the results of office and home BP readings were compared in three groups of men with high BP sampled from the general population. More than 90% of the men were able to perform the measurements. Among men well accustomed to the office environment, the differences between office and home readings were small and without any clinical importance. Among men less well accustomed to the office atmosphere, the office readings exceeded almost invariably the home BP.
Pseudo hypertension of youth: too much of a good thing?
American Journal of Hypertension - AMER J HYPERTENS, 2003
S ince the advent of the modern mercury sphygmomanometer at the turn of the twentieth century, many epidemiological studies have demonstrated a clear relationship between blood pressure (BP) and cardiovascular risk. What is also clear is that, in almost all societies worldwide, BP increases with age. However, whereas systolic BP increases throughout life, diastolic BP rises until middle age, then plateaus, and actually falls after the age of 55 to 60 years. Thus, pulse pressure, the difference between systolic and diastolic BP, widens with age, and accounts for the high prevalence of isolated systolic hypertension in later life; rising from Ͻ5% in individuals Ͻ40 years old to Ͼ50% in the those Ͼ70 years. The underlying pathophysiology of such age-related changes in BP appears to be fatigue fracture of the elastic elements in the walls of the large arteries, which normally function to buffer the cyclical changes in pressure resulting from intermittent ventricular ejection. Stiffer arteries means a higher pulse pressure, as noted nearly 80 years ago by Bramwell and Hill, 1 who were also among the first to demonstrate an increase in aortic stiffness with age.
The relationship of childhood to adult blood pressure
Journal of Hypertension, 2000
Objective To assess changes in blood pressure from childhood to adulthood and the ability to predict adult blood pressure. Design Longitudinal study of a cohort of children with baseline data and a follow-up survey after 20 years. Setting Epidemiological survey of schoolchildren and subsequent inhabitants of Kaunas, a town in Lithuania. Participants The children came from 15 schools and accounted for 25% of all 12-and 13-year-old children born in 1964 in Kaunas. The ®rst survey (n = 1082) was carried out in 1977. The same population was reexamined in 1997 (n = 505). Data from 217 men and 288 women, who participated in both the ®rst and the most recent surveys, is presented. Main outcome measures Systolic and diastolic blood pressure at the age of 32±33 years. Results In the 20 years between the two surveys blood pressure increased more in men than in women. Statistically signi®cant correlation between childhood and adult blood pressure levels was estimated (for systolic blood pressure r = 0.40 in men and r = 0.24 in women; for diastolic blood pressure r = 0.14 in men and r = 0.34 in women). Stepwise regression analysis of the data showed that the best predictors of adult blood pressure were the initial childhood blood pressure levels and change in BMI during the 20-year period for both men and women. Other factors were less predictive. Conclusions Childhood blood pressure is related to adult levels and, together with changes in body mass index, is a signi®cant predictor of adult blood pressure.
Previous blood pressure measurement and associated factors in student adolescents
Einstein (São Paulo), 2015
Objective To identify prevalence of previous blood pressure measurement and analyze some associated factors in adolescents.Methods This cross-sectional study included 6,077 adolescents aged 14 to 19 years. Demographic characteristics included (sex, age, period of study, region of residence, work, skin color, and economic) status, history of blood pressure measurement within last 12 months, local of blood pressure measurement, and reading obtained. To assess associations between previous blood pressure measurement with demographic characteristics and high blood pressure we used descriptive statistics and logistic regression analysis.Results Out of the adolescents, 56.8% reported no blood pressure measurement within the last 12 months. The health centers and the physician’s office were most mentioned places for blood pressure measurement (28.3% and 36.9%, respectively). Boys (odds ratio of 1.64 95%CI: 1.46-1.84) aged 14 to 16 years (odds ratio of 1.12; 95%CI: 1.01-1.25), whose economi...
Blood pressure in a high school population: II. Clinical profile of the juvenile hypertensive
The Journal of Pediatrics, 1979
TheJournalofPEDIATRICS Blood pressure in a high school population II. Clinical profile of the juvenile hypertensive One-hundred-Jburteen hypertensive high school students were ei~aluated tO determine whether a distinctive clinical profile could be identified,~ 71 normotensive students served as controls. Selected blood ehemistry determinations, urinalysis, and chest roentgenograms were done to help rule out secondary causes of hypertension. Left ventricular fimction 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 trigylceride coneentration; basilar hypertrophy by electrocardiogram/vectorcardiogram," electromechanical systole and pre-ejection period shorter, and the ratio Of' the pre-ejection period over the left ventrictilar 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 measurement in epidemiological investigations in teenagers
European journal of epidemiology, 2001
The use of sphygmomanometers may lead to problems in investigations on health of young people. The purpose of this paper is to present the validation of the blood pressure (BP) collected during the survey 'Youth Heart Health' in Hainaut by using second sample of young people in Hainaut for which BP was measured by a manual taking of tension and by an electronic device. Validation was done with a control sample of 343 young with five successive BP measures: twice with the mercury sphygmomanometer and three with DXL. We compared the manual and the electronic measures in order to study the correlation between the two methods. The control sample was used in order to compare the BP measurements with the results of the survey on the health of young people in Hainaut. The differences between manual systolic BP and Dinamap measures are significant (differences in averages 3.6 mmHg; d.s. 7.8; 95% CI: 2.8-4.4 mmHg; p < 0.001) and the regression coefficient is -0.015.
