Foreword
Chapter 4 of this standard are recommended, the rest are mandatory.
This standard replaces GB 16005-1995 "iodine deficiency disorders (IDD) Ward criteria for the classification."
The main changes compared to the Standard and GB 16005-1995 are as follows.
--- Increasing the normative references;
--- Increased sampling and survey methodology;
--- Goiter rate and urinary iodine retain only two to check the crowd of children aged 8 to 10, in addition to children aged 7 to 14, goiter
Rate index;
--- Iodine Deficiency Disease criteria for the classification table of contents sick individual adjustment to increase the frequency distribution of urinary iodine content.
This standard by the Ministry of Health and focal points.
This standard by the People's Republic of China Ministry of Health is responsible for interpretation.
This standard was drafted. Chinese Center for Disease Control of Endemic Diseases Control Center, Jilin Institute of Endemic Diseases Prevention second, Hainan

Deficient areas divided
1 Scope
This standard specifies the determination of deficient areas and deficient areas by type of standard.
This standard applies to the determination of iodine deficiency disorders ward and division.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, all subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. Any undated reference documents, the latest versions apply to this standard.
GB/T 5750 (all parts) drinking water standard test method
WS104 endemic cretinism and endemic subclinical cretinism diagnosis
107 photometric method of urinary iodine arsenic cerium catalytic spectrophotometry WS/T
WS276 endemic goiter diagnostic criteria
3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Due to the natural environment of iodine deficiency, leading to insufficient iodine intake and cause general body iodine malnutrition performance of a group of diseases.
4 deficient areas determined
The township as a unit, along with the following three indicators can be judged to be deficient areas.
a) water iodine. iodide content in drinking water is less than the median 10μg/L;
b) urinary iodine. Children 8 to 10 years median urinary iodine less than 100μg/L, and less than the number of samples 50μg/L accounts for more than 20%;
c) goiter rate. 8 to 10 years old children goiter rate greater than 5%.
Taking iodized salt or other control measures in the region, in line with a) and c) two indicators can be judged to be deficient areas.
5 Types of deficient areas
Deficient areas Classification criteria in Table 1.

NOTE. When the three indicators are inconsistent, 8 to 10 years old children goiter rate based.
6 sampling and testing methods
6.1 iodine water
6.1.1 Sampling Method
The township as a unit, in the east, west, south, north, five orientations randomly selected one administrative villages, each administrative village follow the east, west, south, north,
Each randomly selected a drinking water source, water samples were collected, the case of centralized water supply, the water sample collected 2 peripheral parts.
6.1.2 Detection
The method according to GB/T 5750 regulations, iodide content in drinking water.
In iodide content in drinking water indicates the median survey township drinking water iodine levels.
6.2 urinary iodine
6.2.1 Sampling Method
The township as a unit, in the east, west, south, north, five orientations randomly selected one administrative villages, drawn in a village primary school in the village or township,
Randomly selected 40 children aged 8 to 10 (the number is insufficient, from the neighboring village of complement), free to collect a urine sample.
6.2.2 Detection
The method according to WS/T 107 provisions of detecting urinary iodine content.
With median urinary iodine assessment survey and frequency distribution Township 8 to 10 years old children urinary iodine levels.
6.3 goiter rate
Children above, according to the method prescribed WS276 using thyroid B ultrasound or palpation method to detect thyroid volume or size, calculated
Goiter rate.
6.4 endemic cretinism patient diagnosis
The township as a unit, according to the method prescribed WS104, endemic cretinism diagnosed patients.
