Blood pressure changes with aging: evidence for a cohort effect

Aging : Clinical and Experimental Research

Abstract

Data from cross-sectional surveys show an increase in systolic blood pressure with increasing age. However, cross-sectional data can be misleading. Our purpose in this study is to prospectively describe changes in systolic and diastolic blood pressure levels over time in community-dwelling elderly persons. The participants were 1,917 men and women aged 65 to 98 yr who had participated at least seven years in the Florida Geriatric Research Program, a community-based, multi-phasic health screening program located in Dunedin, Florida (USA). Our results show that contrary to the cross-sectional data, systolic and diastolic blood pressure levels tend to decrease with increasing age. Mean systolic blood pressure in women at the baseline visit (Visit 2) was 143 mmHg and three years later (Visit 5) it had dropped to 140 mmHg. This downward trend was consistent at all ages and for both men and women. Stratification by use of antihypertensive medication, weight change, and survivorship did not alter this association. Further follow-up of this cohort to Visit 7 revealed a U-shaped trend of blood pressure with aging. There was also clear evidence of a cohort effect, as the age-specific mean systolic blood pressure was consistently lower in...Continue Reading

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
