Blood pressure was measured in the north and in the south of the People's Republic of China in 1002 men and 1006 women. The 24-hour urinary excretion of sodium, potassium, calcium, magnesium, and creatinine was measured, and the relationship between urinary cations and blood pressure was studied. Blood pressure and 24-hour sodium excretion were higher in northern China than in southern China. With some exceptions, a positive correlation was found between urinary sodium and blood pressure and a negative one between 24-hour urinary potassium excretion and blood pressure. Urinary calcium correlated negatively and urinary magnesium did not correlate significantly with blood pressure. The sodium/potassium ratio correlated positively with blood pressure, and the calcium/magnesium ratio, negatively. This study confirms the positive within-population relationship between sodium intake and blood pressure in Oriental populations.
对中华人民共和国北方和南方的1002名男性及1006名女性进行了血压测量。测量了24小时尿钠、钾、钙、镁及肌酐排泄量，并研究了尿阳离子与血压之间的关系。中国北方的血压和24小时钠排泄量高于南方。除了一些例外情况，发现尿钠与血压呈正相关，24小时尿钾排泄量与血压呈负相关。尿钙与血压呈负相关，尿镁与血压无显著相关性。钠/钾比值与血压呈正相关，钙/镁比值与血压呈负相关。本研究证实了东方人群中钠摄入量与血压之间在人群内部的正相关关系。
