The cross sectional relationship between blood pressure and current calcium intake was examined in 199 white women aged 46-66 yr with no history of hypertension. Calcium intake was assessed from 3-day food logs and from elemental calcium composition of the reported calcium supplement. No significant correlation between calcium intake and blood pressure was detected even after controlling for other known risk factors for hypertension. In logistic regression analysis, the relative risk of having a systolic blood pressure greater than or equal to 130 mmHg, or a diastolic blood pressure greater than or equal to 90 mmHg according to calcium intake, was not significantly different from 1.0. These data suggest that dietary manipulation of calcium intake may not be beneficial in the prevention or treatment of hypertension in older women.
对199名年龄在46至66岁之间且无高血压病史的白人女性,研究了血压与当前钙摄入量之间的横断面关系。通过3天的食物记录以及所报告钙补充剂的元素钙成分来评估钙摄入量。即使在控制了其他已知的高血压危险因素之后,也未检测到钙摄入量与血压之间存在显著相关性。在逻辑回归分析中,根据钙摄入量,收缩压大于或等于130 mmHg或舒张压大于或等于90 mmHg的相对风险与1.0无显著差异。这些数据表明,通过饮食控制钙摄入量可能对老年女性预防或治疗高血压并无益处。
