Detection of Urine Iodine Content in School-age Children in Luxi County and Analysis of Its Related Influencing Factors
Objectives To explore the detection of urinary iodine content in school-age children in Luxi County and its related influencing factors.Methods A total of 200 school-age children who underwent urine iodine level moni-toringwere selected as the research subjects.We collect5mL of daytime urine to detect the iodine content,and the results of urine iodine content testing and iodine nutritional status were analyzed and recorded,so as to analyze the relevant factors affecting the iodine nutritional status of school-age children in Luxi County.Results The urinary iodine content of school-age children in Luxi County was 31.4~1168.90 μg/L,and the median urinary iodine was 292.35 μg/L.The median urinary iodine of 8-year-old children was 249.93 μg/L,the median urinary iodine of 9-year-old children was 312.43 μg/L,and the median urinary iodine of 10-year-old children was 255.10 μg/L.Among the 200 school-age children,there were 15 cases of iodine deficiency(7.50%),45 cases of iodine suitability(22.50%),80 cases of iodine superappropriateness(40.00%),and 60 cases of iodine excessiveness(30.00%).There were statistically significant differences in iodine nutritional status among school-age children of different ages,gen-ders,body mass index(BMI),salt intake,frequency of seafood consumption in the past week,and frequency of egg consumption in the past week(P<0.05).There was no statistically significant difference in iodine nutritional status a-mong school-age children with different types of salt,frequency of meat consumption in the past week,anddairy in-take in the past week(P>0.05).Logistic regression analysis showed that female(β=1.394,OR=4.030,95%CI=1.881~8.635),BMI≥24 kg/m2(β=2.418,OR=11.227,95%CI=2.316~54.431),salt intake≥6g/d(β=1.386,OR=4.000,95%CI=1.205~13.283),frequency of seafood consumption≤2 timesin the past week(β=0.933,OR=2.541,95%CI=1.148~5.625),frequency of egg consumption>2 times in the past week(β=1.078,OR=2.940,95%CI=1.279~6.758)were high-risk factors for iodine nutritional status of school-age children in Luxi County(P<0.05).Conclusions Some school-age children in Luxi County have iodine nutritional abnormalities,which are influenced by gender,BMI,salt intake,frequency of seafood and egg consumption.
