Abstract
A corrected urinary concentration method was presented to simplify the nutritionaljudgment as to vitamins status in human bodies.
The standard concentration of vitamins in urine was obtained according to the correspondingcreatinine concentration as the equation (1) as well as Tables 2and 3, whichwere deduced from the urine of 445 seamen and 843 village women;the details of thesame were shown in Table 1.
The nutritional judgement is to be made on the basis of the values of standard deviationscalculated from each vitamin.
Reliability of this method was examined by comparing the results with concentrationsin blood and with that of saturation method, and it was found that the correlation coefficientbetween blood concentration and corrected urinary concentration was higher thanthat between blood concentration and excretion rate obtained by saturation method.
This paper is to report of a nutrition survey about vitamin status of seamen, villagewomen and prisoners by using the above corrected concentration method.
