適用範囲

This standard is applicable to the discriminant and classification of endemic areas of iodine deficiency disorders (IDD) within the People's Republic of China. It is primarily intended for use by public health authorities, epidemiological survey teams, and local disease control centers to identify and categorize affected regions. The standard specifically targets rural villages or urban communities as the fundamental units for assessment.

技術要求

GB 16005-2025 establishes the criteria for identifying and classifying iodine-deficient areas. An area is designated as an IDD endemic area if the median water iodine level is below a specific threshold and meets certain clinical or subclinical indicators. These indicators include the presence of newly occurring endemic cretinism cases, a specific thyroid goiter rate among children aged 8 to 10, and median urinary iodine concentrations falling below defined limits. Furthermore, the standard classifies identified endemic areas into three severity tiers: mild, moderate, and severe. This classification is based on a matrix of the thyroid goiter rate (TGR) and median urinary iodine (MUI) levels in children. Accurate categorization is mandatory for implementing appropriate public health interventions. The standard also outlines specific sampling methodologies for water iodine, urinary iodine, and thyroid volume investigations to ensure statistical validity.

試験方法

The standard mandates specific sampling and testing methodologies to ensure accurate data collection. Water samples must be collected and preserved according to GB/T 5750.2 and tested using GB/T 5750.5. Urinary iodine is determined using WS/T 107.1 or WS/T 107.2. Clinical diagnoses for endemic goiter and cretinism must follow WS/T 10027 and WS/T 104 respectively. Strict adherence to these referenced testing protocols is required for valid area classification.

よくある質問

What is the scope of GB 16005-2025?

GB 16005-2025 applies to the discriminant and classification of endemic areas of iodine deficiency disorders. It is used by public health authorities and epidemiological survey teams to identify and categorize affected regions based on environmental and physiological indicators.

What are the main updates in GB 16005-2025 compared to the 2009 version?

The 2025 version changes the definition of iodine deficiency disorders, updates the划定 unit (delineation unit) for endemic areas, modifies the technical indicators for classification, and revises the sampling methods detailed in Annex A.

Does GB 16005-2025 reference any international standards?

The standard references several Chinese standards for testing, including GB/T 5750.2 and GB/T 5750.5 for water iodine, and WS/T 107.1 and WS/T 107.2 for urinary iodine. While the testing principles may align with international ISO or WHO guidelines, compliance in China strictly requires following these referenced domestic standards.
