In a double-blind, placebo-controlled trial with 58 normotensive female students, the effect of oral-calcium supplementation (1500 mg Ca++/day for 6 wk) on diastolic and systolic blood pressure was studied while students were consuming a low-calcium diet (500 mg Ca++/day) by restricting the intake of dairy products. Results show that, in both the calcium- and placebo-supplemented groups, blood pressure values decreased slightly and no effect of oral-calcium supplementation on blood pressure could be demonstrated. In addition, at baseline neither systolic nor diastolic blood pressure correlated with habitual calcium intake. Diastolic but not systolic blood pressure correlated significantly with body mass index (r = 0.31, p = 0.01). It is concluded that oral-calcium supplementation for 6 wk does not influence blood pressure in young, healthy normotensive females consuming low-calcium diet.
在一项针对58名血压正常的女学生的双盲、安慰剂对照试验中，研究了口服补钙（每天1500毫克钙离子，持续6周）对舒张压和收缩压的影响，试验期间学生们通过限制乳制品摄入量来食用低钙饮食（每天500毫克钙离子）。结果显示，在补钙组和安慰剂组中，血压值均略有下降，未发现口服补钙对血压有影响。此外，在基线时，收缩压和舒张压均与习惯性钙摄入量无关。舒张压与体重指数显著相关（r = 0.31，p = 0.01），而收缩压则不然。得出的结论是，对于食用低钙饮食的年轻、健康的血压正常女性，口服补钙6周不会影响血压。
