A study of biochemical indicators for objective evaluation of life style

主题是由大学的职员和一年级学生组成的。盐和蛋白质的摄入量作为饮食寿命的生化指标，是根据尿中钠和氮的含量来估算的。血清硫氰酸盐（SCN）对习惯性吸烟行为的可用性进行了估计。得到的结果如下：1。男职员和男学生的平均盐摄入量估计为16克，女职员为12克，女学生为8克。盐与血压之间的相关性在学生中高于教师。据估计，男职员的平均蛋白质摄入量为78克，男学生为89克，女职员和女学生约为60克。在女生中，蛋白质摄入量与血红蛋白略有相关。对于SCN，区分吸烟者和非吸烟者的最佳临界值为55mumol/l，其敏感性为91%，特异性为88%。在男性员工中，每天吸烟10支以内的SCN超过临界值的比例为56%，吸烟11-20支的比例为96%，吸烟21支以上的比例为100%。在男学生中，这一比例为57%，甚至更高。21 cigarettes.5。吸烟者自我报告的SCN和估计的SCN比例相似。但是，在女性和18岁的男性学生中，SCN估计的吸烟者比例高于自我报告的吸烟者比例。

The subjects consisted on the stuffs and first-grade students of the uiniversity. As the biochemical indicators of dietary life, salt and protein intake were estimated upon sodium-and ure^a-nitrogen in spot urine. And, serum thiocyanate (SCN) was estimated the availability for habitual smoking behavior.The results obtained were as follows ;1. Average salt intake estimated was 16g in male staff and male student, 12g in female stuff, 8g in female student. The correlation between salt and blood pressure was higher in student than staff.2. Average protein intake-estimated was 78g in male staff, 89g in male student, about 60g in female staff and female student. On female students, protein intake slightly correlated to hemoglobin.3. For SCN the best cut-off value to distinguish smokers from nonsmokers was 55mumol/l, which yielded a sensitivity of 91% and a specificity of 88%.4. In male staffs, the rate of those SCN was over the cut-off value was 56% in smokers of within 10 cigarettes per day, 96% in 11-20 cigarettes and 100% in more than 21 cigarettes. In male students, the rate was 57% in even more than. 21 cigarettes.5. The rate of smokers on self-reported and estimated on SCN were similar. But, in females and 18 years male students, the rate of smokers estimated on SCN was higher than that on self-reported.
