- Some governments have implemented educational and support programs, but accessibility remains a challenge.
3. Factors Influencing Down Syndrome Global Statistics
Maternal Age and Birth Rates
- The likelihood of giving birth to a child with Down syndrome increases with maternal age:
- At age 20 – Probability: 1 in 1,441.
- At age 30 – Probability: 1 in 959.
- At age 40 – Probability: 1 in 84 (Mayo Clinic).
Prenatal Screening & Elective Termination
- Countries with advanced genetic screening programs report lower Down syndrome birth rates.
- In some European and Asian countries, elective termination following a positive Down syndrome diagnosis has led to a decline in birth rates.
Cultural and Societal Attitudes
- Western nations promote inclusive education, medical research, and social support, improving the quality of life.
- In contrast, some cultural and religious perspectives discourage elective termination, leading to higher Down syndrome birth prevalence.
4. Health Challenges Faced by Individuals with Down Syndrome
Congenital Heart Defects
- 50% of babies born with Down syndrome have congenital heart defects.
- Common conditions include atrial septal defect (ASD) and ventricular septal defect (VSD).
Respiratory & Immune System Issues
- Increased risk of pneumonia, lung infections, and hearing loss.
- Higher likelihood of thyroid disorders and autoimmune diseases.
