ABSTRACT
Objective To investigate and evaluate the iodine nutritional status of school-age children in Yi county of Heibei Province,and to provide scientific basis for the development of control measures to iodine deficiency disorders.Methods Retrospectinely analyzed school-age children urinary iodine monitoring results of Yi County of Hebei Province from 1998 to 2011.One township was selected randomly in each of the five directions (east,west,south,north and center) from 1998 to 2011.One elementary school was randomly chosen in each of the five townships.And at least 20 urine samples of 8-10 years old children were randomly collected in each school selected.Urinary iodine contents were determined through arsenic cerium catalytic spectrophotometric method.Urinary iodine determination standard according to The Standard of Iodine Deficiency Disorders Elinination (GB 16006-2008) and The Iodine Deficiency Disorders Elinination Guide.Results A total of 1725 children urinary samples were collected from 1998 to 2011,urinary median was 243.26 μg/L,each of the median urinary iodine was higher than 100 μg/L.The ratio of urinary iodine less than 100 μg/L was < 50% over the years,and less than 50 μg/L was < 20%.Overall,the highest value of urinary iodine stayed at approximately 200 μg/L,showing positively skewed distribution that was skewed to the right.Urinary iodine level was compared among different ages,gender and ethnicity,and the difference was not statistically significant(P > 0.05).Conclusions In recent years,the iodine intake of school-age children of Yi County can meet the body needs,and the iodine nutrition is at an appropriate level.
