What is the prevalence of Down Syndrome?
How many people does Down Syndrome affect? Does it have the same prevalence in men and women? And in the different countries?
Down Syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. It is the most common chromosomal condition, affecting approximately 1 in every 700 births worldwide. The prevalence of Down Syndrome varies across different populations and is influenced by factors such as maternal age. Although it is associated with certain physical and intellectual disabilities, individuals with Down Syndrome can lead fulfilling lives with appropriate support and opportunities for inclusion.
Down Syndrome, also known as Trisomy 21, is a genetic disorder caused by the presence of an extra copy of chromosome 21. It is the most common chromosomal abnormality in humans.
The prevalence of Down Syndrome varies across populations and is influenced by factors such as maternal age. On average, it is estimated that approximately 1 in every 700 to 1,000 live births worldwide is affected by Down Syndrome.
Maternal age is a significant risk factor for Down Syndrome. The chance of having a baby with Down Syndrome increases as the mother's age advances, particularly after the age of 35. However, the majority of babies with Down Syndrome are born to women under the age of 35, simply because younger women have more births overall.
While the prevalence of Down Syndrome remains relatively consistent across different ethnicities, it is important to note that the actual numbers may vary due to differences in population size and demographics.
It is crucial to provide support, resources, and inclusive environments for individuals with Down Syndrome and their families to ensure they can lead fulfilling lives and reach their full potential.
