Relative weight and blood pressure in four Chicago epidemiologic studies
1982
Abstract Because systolic blood pressure rises more sharply with age than diastolic blood pressure, leading to an increasing prevalence with advancing age of elevated systolic blood pressure without elevated diastolic pressure, i.e. so-called pure systolic hypertension, the question arises as to whether or not pure systolic hypertension has its own etiology and pathogenesis. Since pure systolic hypertension is characterized by a widened pulse pressure, the present report examined the association between relative weight and pulse pressure, both cross-sectionally and prospectively, in addition, to the association between relative weight and the level of blood pressure, in four Chicago epidemiologic studies. The positive association between relative weight and the level of blood pressure in these studies, in both cross-sectional and prospective analyses, reaffirms the finding in previous studies of a positive association between weight and blood pressure and the prevalence and incidence of hypertension. However, the results of these studies did not generally support the hypothesis that relative weight is related to pulse pressure, and thus possibly to pure systolic hypertension.
