Abstract

This analysis of the third National Health and Nutrition Examination Survey (NHANES III) was designed to investigate the impact of dietary calcium intake on age-related changes in blood pressure and pulse pressure. Data on 17,030 participants 20 years or older (mean age, 48.8±0.2 years; 47% male, 42% Gaucasian, and 28% African American) were used. Data included demographics, body mass index, blood pressure, and daily dietary calcium. Overall, average calcium intake was 761 mg/day. After adjusting for demographic and anthropomorphic variables, as well as total energy consumption, higher calcium intake was associated with lower rates of age-related increases of systolic blood pressure and pulse pressure (p<0.001). If the calcium intake of the general population were to increase to above 1200 mg, the incidence of isolated systolic hypertension in the elderly might be decreased.
