作者为了解血压和Na、K的摄入量关系,对罔山县西南部脑卒中死亡率较低的510名(40～69岁)女性居民调查其血压与尿中Na、K浓度间的关系。 在室温(>20℃)中采尿后随即测血压,同时测定尿比重,部分尿送实验室以柯勒曼51型、51Ca型荧光光度计测定Na、K浓度(以1.024尿比重校正之)。 调查对象的高血压程度: Sp/Dp在>160/95mmHg者占11.8％,年龄45岁的占4.8％,50岁的占10.7％,60岁的占20％;均值:Sp及K浓度的均值随年龄的增加而有升高的倾向,Na/K比呈下降倾向;与血压的关系:Na浓度与血压呈正相关但无显著意义,除40岁
To understand the relationship between blood pressure and Na and K intake, 510 (40-69) female residents with lower stroke mortality in southwestern Luupanshan County were investigated for their relationship with blood levels of Na and K in urine . Blood pressure was measured immediately after urine collection at room temperature (> 20 ° C), and the urine specific gravity was measured at the same time. The concentrations of Na and K in the urine were measured by a Kohlmann 51 and 51Ca fluorophotometer (corrected to 1.024 urine specific gravity) . The level of hypertension in subjects was: Sp / Dp accounted for 11.8% at> 160 / 95mmHg, 4.8% at age 45, 10.7% at age 50, and 20% at age 60; mean: Sp and K mean Na / K ratio tends to decrease with the increase of age. The relationship with the blood pressure: There is a positive correlation between Na concentration and blood pressure, but no significant difference except for the age of 40
