Abortion in women with Down syndrome.

Doctors looked at every known pregnancy in Swiss women who have Down syndrome. They wanted to know how many ended in abortion and why.

The team checked hospital records and prenatal files. They counted pregnancies and the reasons doctors gave for ending them.

About two out of every three pregnancies were aborted. The main reason listed was "maternal Down syndrome," not heart defects or other medical problems.

In other words, the baby was terminated because the mother herself had DS.

Dargue et al. (2021) show ABA helps people with Down syndrome talk and behave better. That work assumes children will be born and receive therapy. Lotfizadeh et al. (2020) shows most pregnancies never reach that point.

Hagopian et al. (1999) and Whitehouse et al. (2014) track the same Swiss adults later in life. They worry about early menopause and dementia. The abortion paper reveals an earlier filter: many never enter those long-term studies because they are not born.

Klein et al. (2024) warn that women with DS over 50 break bones more often. Fall-prevention plans only help the women who survive birth and childhood.

If you write behavior plans for teens or adults with DS, remember you serve a small survivor group. When you teach sex-ed or parenting skills, pair them with clear prenatal counseling and self-advocacy training. Help families see that ABA evidence (Nicole et al., 2021) supports a full, capable life. Your data can counter the bias that ends two-thirds of these pregnancies.
