GB16006-1995
This standard is based on Table 10 "Standards for Eliminating IDD as a Public Health Problem" in the "Indicators for the Assessment and Evaluation of Iodine Deficiency Disorders and Their Prevention and Control Programs" recommended by WHO, UNICEF and ICCIDD, approved from November 3 to 5, 1992, and revised in September 1993, and is formulated in combination with my country's national conditions. It is equivalent to the international standard in terms of technical content, so that my country's standards can be aligned with international standards as soon as possible to meet the needs of eliminating iodine deficiency disorders in 2000. In 1990, the 71-nation Summit adopted the "World Declaration on the Survival, Protection and Development of Children" and formulated a work plan for the 1990s, one of the important contents of which is "eliminating iodine deficiency disorders worldwide in 2000". In September 1993, the State Council, WHO, U-NICEF and other international organizations held the "China 2000 Elimination of Iodine Deficiency Disorders Mobilization Conference" in Beijing, and formulated the "Outline of China's 2000 Elimination of Iodine Deficiency Disorders Plan". The "Outline" requires that during the "Ninth Five-Year Plan" period, all salt in the country will be iodized, and qualified iodized salt will cover 95% of the population. In 1994, my country also formulated and issued the "Regulations on the Management of Iodine Addition to Salt to Eliminate the Hazards of Iodine Deficiency". The "Regulations" stipulate that my country implements a monopoly on salt and a licensing system for the production and wholesale of salt. This ensures that my country will eliminate iodine deficiency diseases in 2000, and is also the basis and foundation for the formulation of my country's "Iodine Deficiency Disorder Elimination Standard". Appendix A, Appendix B and Appendix C of this standard are all appendices to the standard. This standard was proposed by the Ministry of Health of the People's Republic of China. The drafting unit of this standard is the Endemic Disease Research Office of Hebei Medical College. The main drafters of this standard are: Zhu Huimin, Yu Zhiheng, and Zhao Wenyuan. This standard is entrusted by the Ministry of Health to the technical management unit of the China Center for Endemic Disease Control and Prevention to interpret it. 448

The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and the parties using this standard should explore the possibility of using the latest versions of the following standards. GB16004-1995 Diagnosis and Grading Standards for Endemic Goiter GB16398-1996 Normal Values ​​of Thyroid Volume in Children and Adolescents The Assessment and Evaluation Indicators for Iodine Deficiency Disorders and Their Prevention and Control Programs jointly recommended by the World Health Organization, the United Nations Children's Fund, and the International Council for the Control of Iodine Deficiency Disorders
3 Elimination Standards for Iodine Deficiency Disorders
3.1 Iodized Salt (Calculated as Iodide Ion)
The qualified rate of iodized salt is greater than 90%. Qualified iodized salt refers to the iodized salt levels at three levels: processing plants (warehouses, wholesale outlets), sales outlets, and users. More than 90% of the samples are not less than 40mg/kg, 30mg/kg, and 20mg/kg, respectively. 3.2 Thyroid Size
Students aged 8 to 10 years old (the age range can be expanded to 6 to 12 years old). Palpation diagnosis (mandatory indicator): The rate of thyroid enlargement is less than 5%. See GB16004, Assessment and Evaluation Indicators for Iodine Deficiency Disorders and Their Prevention and Control Programs.
Ultrasound diagnosis (optional indicator): The rate of thyroid enlargement is less than 5%, that is, the thyroid volume of children aged 8, 9, and 10 in the target population is greater than 4.5ml, 5.0mL, and 6.0mL respectively, which is considered to be goiter. See GB16398. 3.3 Biochemical indicators
Urinary iodine (mandatory indicator): For school students aged 8 to 10, the median urine iodine is greater than or equal to 100ug/L, and the number of samples less than 20μg/L shall not exceed 10%. See the assessment and evaluation indicators of iodine deficiency and its prevention and control plan. TSH level (optional indicator): The rate of TSH level greater than 5mU/L measured by the whole blood TSH paper method (enzyme-linked immunosorbent assay or immunoradiometric assay) of newborns is less than 3%. See the assessment and evaluation indicators of iodine deficiency and its prevention and control plan. Approved by the State Administration of Technical Supervision on December 15, 1995 and implemented on July 1, 1996
A1 Grading Standard
GB16006—1995
Appendix A
(Appendix to the standard)wwW.bzxz.Net
Diagnosis and Grading Standard of Endemic GoiterNo palpable or visible thyroid enlargement (invisible or intangible). A1.21 Degree
When the neck is in a normal position, the enlarged thyroid gland can be touched, but it cannot be seen with the eyes (invisible). When the patient swallows, the enlarged thyroid gland can move up and down the neck. Even when the thyroid gland is not enlarged, the presence of thyroid nodules is classified as this degree. A1.3I Degree
When the neck is in a normal position, obvious enlargement can be seen in the neck, and the enlarged thyroid gland can be found when the neck is palpated at the same time. When the thyroid gland volume is between two levels and it is difficult to determine which level it belongs to, it can be classified as a lower level. The calculation of the thyroid enlargement rate includes the sum of the cases in the two grades of I and straightness as a percentage of the number of people examined. Appendix B

Standards for normal thyroid volume for school-age children and adolescents B1 Standards for normal thyroid volume
See Table B1 for the standards for normal thyroid volume. Table B1
Standards for normal thyroid volume
Normal thyroid volume, mL
Boundaries for judging enlarged and normal thyroid
GB16006—1995
When using an ultrasound to examine the thyroid, the thyroid volume is divided into only two states: "enlarged" and "normal". Those of each age group exceeding the boundary value in the table are enlarged, and vice versa.
