A community survey uses the Total Goiter Rate (TGR) to assess the prevalence of iodine deficiency disorders in school-aged children. According to WHO, what TGR threshold classifies iodine deficiency as a public health problem in that community?

• A 20 percent
• B 15 percent
• C 10 percent
• D 5 percent ✓

Explanation

WHO classifies a Total Goiter Rate greater than 5 percent in school-aged children as indicative of a public health problem due to iodine deficiency. D TGR of 5.0 to 19.9 percent indicates mild deficiency, while 20 percent or higher indicates moderate to severe deficiency. The threshold for action remains 5 percent.
