A village has a high prevalence of goitre and cretinism. The water sample analysis reveals a specific deficiency. Which additional parameter in the water would most likely be associated with this condition?

  • A Low calcium
  • B Low fluoride
  • C Low iodine
  • D Low iron
Correct answer: C. Low iodine

Explanation

Goitre and cretinism in a village setting indicate iodine deficiency disorders (IDD). While the question mentions water analysis, the key association is low iodine in the environment (water, soil, food). Low calcium causes rickets or osteomalacia. Low fluoride causes dental caries. Low iron causes anemia. Iodine deficiency is the cause of endemic goitre and cretinism.
