適用範囲
This standard defines the criteria for the delimitation and classification of endemic areas of iodine deficiency disorders (IDD) in China. It is specifically applicable to public health surveys and regional assessments conducted at the township level. It serves as the official guideline for identifying IDD-endemic areas and categorizing their severity. The standard is intended for use by health authorities and disease control centers, referencing methodologies outlined in WS 104 and WS 276.
技術要求
The standard outlines the mandatory criteria for identifying an IDD-endemic area, which requires the simultaneous evaluation of three primary indicators: water iodine levels, urinary iodine in children, and thyroid goiter rate (TGR). Areas that have implemented preventive measures like iodized salt can be classified based on only water iodine and TGR. Furthermore, the standard classifies endemic areas into three severity tiers: light endemic areas, medium endemic areas, and severe endemic areas. This classification is determined by specific threshold ranges for children's urinary iodine medians, the percentage of samples below 50 μg/L, the total goiter rate, and the presence of endemic cretinism. When the three main indicators show inconsistent results, the 8-10 year old children's thyroid goiter rate serves as the decisive factor.
試験方法
The standard mandates specific sampling and detection methodologies to ensure accurate regional assessment. Water iodine sampling requires collecting from five geographical directions within a township, tested via methods specified in GB/T 5750. Urinary iodine is assessed by randomly selecting 40 children per village, utilizing the WS/T 107 detection method. Thyroid assessments must be conducted using either B-ultrasound or palpation methods. Additionally, the diagnosis of endemic cretinism is conducted according to WS 104 protocols.
よくある質問
What is the primary scope of GB 16005-2009?
It applies to the delimitation and classification of endemic areas of iodine deficiency disorders (IDD) in China, primarily using the township as the basic assessment unit.
What are the main updates in GB 16005-2009 compared to the 1995 version?
The updated version added normative references and sampling methods, shifted the focus exclusively to 8-10 year old children (removing 7-14 year olds), and introduced the frequency distribution of urinary iodine into the classification criteria.
Which testing standards are referenced in GB 16005-2009?
It relies on Chinese industry standards such as GB/T 5750 for water testing, WS/T 107 for urinary iodine, WS 276 for thyroid diagnosis, and WS 104 for endemic cretinism diagnosis.
