Dietary intakes of various nutrients, urinary electrolyte levels from a casual urine sample, and BP were determined in 425 active men and women aged 60 and above (mean age 70.6 years) living in the community. After exclusion of subjects taking Western or Chinese medicines, correlations were seen between body mass index and diastolic blood pressure (DBP, r = 0.15, P less than 0.01), between calcium intake and systolic blood pressure (SBP, r = 0.14, P less than 0.02) and retinol intake and SBP (r = -0.14, P less than 0.03). There was no significant correlation between BP and casual urinary Na/Cr, K/Cr, Na/K or Ca/Cr ratios. Fewer correlates were seen compared to younger age groups. These results suggest that dietary modification of BP based on studies in Caucasian communities of all ages may not apply to elderly Chinese populations.
对居住在社区的425名60岁及以上（平均年龄70.6岁）的活跃男性和女性，测定了各种营养素的膳食摄入量、随机尿样中的尿电解质水平以及血压。在排除服用西药或中药的受试者后，观察到体重指数与舒张压（DBP，r = 0.15，P<0.01）、钙摄入量与收缩压（SBP，r = 0.14，P<0.02）以及视黄醇摄入量与SBP（r = -0.14，P<0.03）之间存在相关性。血压与随机尿钠/肌酐、钾/肌酐、钠/钾或钙/肌酐比值之间无显著相关性。与较年轻年龄组相比，相关性较少。这些结果表明，基于对各年龄段白种人群体研究的血压饮食调整可能不适用于老年中国人群。
