Iodine Deficiency Disorders (IDD) Spectrum
| Life Stage | Manifestation |
|---|---|
| Fetus | Abortion, stillbirth, congenital anomalies, and endemic cretinism. |
| Neonates | Neonatal hypothyroidism, increased neonatal mortality. |
| Children/Adolescents | Goiter, hypothyroidism, impaired mental function, retarded physical development. |
| Adults | Goiter, hypothyroidism, impaired mental function. |
High-Yield NEET PG Pearls:
- Universal Salt Iodization (USI): The most effective public health strategy for the elimination of IDD.
- Assessment: Urinary Iodine Excretion (UIE) is the best indicator of recent dietary intake.
- Goiter Index: Used for assessing the magnitude of IDD in a community (via palpation or ultrasound).
- Endemic Cretinism: Two main types—
- Neurological (deaf-mutism, squint, motor rigidity) and
- Myxedematous (hypothyroidism, stunted growth).
