  • an 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% Caucasian, and 28% African American) were used
    • other data included demographics, body mass index, blood pressure, and daily dietary calcium
    • analysis
      • after adjustment 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)
    • the study authors concluded
      • 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
