Early detection of congenital hypothyroidism (CH) through newborn screening is crucial for preventing intellectual disabilities. These public health programs efficiently diagnose CH, reducing associated morbidities and improving outcomes.
Area of Science:
- Endocrinology
- Public Health
- Pediatrics
Background:
- Congenital hypothyroidism (CH) is a leading preventable cause of intellectual disability.
- Early detection and treatment of CH in newborns are vital for reducing mortality and developmental issues.
- Neonatal screening programs are essential for identifying CH promptly.
Purpose of the Study:
- To emphasize the importance of CH detection programs.
- To review the current global and national status of CH screening.
- To identify challenges and future directions in CH detection.
Main Methods:
- Literature review of studies and reviews on CH.
- Analysis of published data from various CH screening programs.
- Consultation of scientific society guidelines and official organizational documents.
Main Results:
- Early CH detection has proven highly efficient in diagnosing the condition.
- Screening programs demonstrate effectiveness through case detection, positive predictive values, and prevalence data.
- Evidence confirms the success of early detection in managing CH.
Conclusions:
- Neonatal screening for primary CH represents a significant public health achievement.
- Further research is needed to determine the benefits of early detection for moderate CH forms.
- Optimizing screening protocols can enhance outcomes for affected infants.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
