The relationship of diet to blood pressure was studied in a total of 705 men and women aged 40-59 from three Chinese population samples having different mean blood pressure and dietary sodium and animal protein intake. Two groups were farmers from Shanxi in northern China, and Guangxi in southern China, and the third were fishermen from Zhejiang, eastern China. Three 24-hour dietary recalls were done for each participant. Serum and overnight urine amino acids were measured in random subsamples. Determination of electrolytes in three 24-hour urine specimens was done in an additional sample of 59 men in each population. Results of multiple or stepwise regression showed: 1) in the pooled group, individual intake of sodium was positively associated with systolic blood pressure; 2) when stratifying by median calcium intake, a positive association of dietary sodium or sodium/potassium was found only in the group with calcium intake lower than the median; 3) daily intake of animal protein, urinary sulphate and certain serum and urine amino acids formed from protein metabolism, were inversely associated with blood pressure.
在中国三个平均血压、膳食钠和动物蛋白摄入量不同的人群样本中，对705名年龄在40至59岁之间的男性和女性进行了饮食与血压关系的研究。其中两组是来自中国北方山西和南方广西的农民，第三组是来自中国东部浙江的渔民。对每位参与者进行了三次24小时饮食回顾。在随机抽取的子样本中测量血清和过夜尿液中的氨基酸。在每个群体中另外抽取59名男性样本，对其三份24小时尿液样本中的电解质进行测定。多元或逐步回归结果显示：1）在合并组中，个体钠摄入量与收缩压呈正相关；2）按钙摄入量中位数分层时，仅在钙摄入量低于中位数的组中发现膳食钠或钠/钾与血压呈正相关；3）动物蛋白的每日摄入量、尿硫酸盐以及蛋白质代谢产生的某些血清和尿液氨基酸与血压呈负相关。
