Question
What is the normal risk rate for Down syndrome?
Answer
Down syndrome, also known as trisomy 21, is a congenital condition caused by chromosomal inflammation that leads to high rates of intellectual disability in newborns. The risk rate is between 1 in 700 and 1 in 1000, and it tends to increase with age. For pregnant women at a higher risk, to prevent the birth of a child with intellectual disability from causing significant emotional and financial burden on the family, it is essential to undergo non-invasive DNA testing or amniocentesis for a thorough examination. The Down syndrome screening is not a definitive result but a risk factor; it does not mean that a low risk guarantees there will be no issue, nor does a high risk mean it will definitely occur. Pay attention to nutrition, rest, maintain a cheerful mood, ensure adequate sleep, and live a regular lifestyle to aid the growth and development of the fetus.
