ABSTRACT
Objective:
The iodine excretion of adult individuals was calculated by two creatinine correction methods of urinary iodine, and the significance and value of the methods to measure individual iodine nutrition levels were assessed to provide a reference basis for further epidemiological investigation and study of iodine deficiency disorders.Methods:
Healthy adults aged 18 - 59 years from Fujian Province were recruited and their 24 h urine, fasting urine, and morning spot urine (800 - 1230) were collected and the corresponding urinary iodine and creatinine concentrations were measured. The estimated 24 h urinary iodine excretion was calculated using two different creatinine correction and creatinine estimation formulas were compared with the measured 24 h urinary iodine excretion.Results:
There were no significant differences in measured 24 h urinary iodine excretion value, estimated 24 h urinary iodine excretion value 1 of fasting urine and morning spot urine, and estimated 24 h urinary iodine excretion 2 of fasting urine and morning spot urine between genders (μg/d 195.5 vs 190.9, 190.0 vs 181.7, 160.2 vs 144.2, 174.8 vs 179.2, 148.3 vs 131.5); there were no significant differences in measured 24 h urinary iodine excretion and fasting urinary estimated 24 h urinary iodine excretion 1, estimated 24 h urinary iodine excretion 2 ( P > 0.05), and there were significant differences in measured 24 h urinary iodine excretion and morning spot urinary estimated 24 h urinary iodine excretion 1, estimated 24 h urinary iodine excretion 2 ( P < 0.01). And there were significant linear correlations between measured 24 h urinary iodine excretion and estimated 24 h urinary iodine excretion 1 of fasting urine and morning spot urine, estimated 24 h urinary iodine excretion 2 of fasting urine and morning spot urine ( r = 0.772, 0.266, 0.828, 0.391, P < 0.01).Conclusions:
It is feasible to estimate 24 h urinary iodine excretion in adults with creatinine-corrected fasting urinary iodine concentration. Creatinine-corrected fasting urinary iodine concentration can be used as an individual iodine nutrition level evaluation index, but whether it is applicable to children and pregnant women remains to be further studied.
