5 Questions
What are the consequences of iodine deficiency disorders (IDDs)?
The consequences of IDD include goitre, cretinism, hypothyroidism, abortion, stillbirth, brain damage, learning disabilities, mental retardation, psychomotor defects, hearing and speech impairment.
What is the main cause of preventable brain damage globally?
Iodine deficiency is the single largest cause of preventable brain damage globally.
How does the rapid environmental change affect iodine levels?
Rapidly changing environmental conditions lead to depletion of iodine from the top layers of the soil, resulting in low iodine content in livestock, vegetation, and humans.
What were iodine deficiency disorders (IDDs) historically associated with?
Historically, IDD was causally associated with goitre and cretinism.
What are the effects of iodine deficiency on mental and physical development?
Iodine deficiency can lead to suboptimal mental and physical development due to its role in thyroid hormone production.
Study Notes
National Iodine Deficiency Disorders Control Programme
- Iodine is a trace mineral essential for optimal mental and physical development and is a key component of thyroid hormones.
- Iodine deficiency is the leading cause of preventable brain damage globally.
- Iodine deficiency disorders (IDDs) include: • Goitre • Cretinism • Hypothyroidism • Abortion • Stillbirth • Brain damage • Learning disabilities • Mental retardation • Psychomotor defects • Hearing and speech impairment
- Environmental changes, such as: • Melting of glaciers • Frequent floods • Change of river beds • Loss of forest cover
- Have led to the depletion of iodine from top soil layers.
- Low iodine content in soil results in: • Low iodine in livestock and vegetation dependent on the soil • Low iodine in humans consuming these livestock and vegetation
- Historically, iodine deficiency was only linked to: • Goitre • Cretinism
- Recent research over the past three decades has expanded the understanding of iodine deficiency disorders.
Test your knowledge on the National Iodine Deficiency Disorders Control Programme and learn about the importance of iodine for mental and physical development. Assess your understanding of iodine deficiency disorders and their effects on health.
