The stillbirth risk calculator allows you to estimate the odds of stillbirth based on maternal characteristics: her comorbidities, obstetric history, and possible addictions.

The article below will shortly discuss a few important topics connected to the subject:

  • Stillbirth vs. miscarriage;
  • How common is stillbirth; and
  • What are the causes of stillbirth.
💡 Our calculations are purely statistical and may or may not depict the exact situation of a particular case. Remember that our stillbirth calculator may not take into account all the existing factors.

What's the difference between stillbirth vs. miscarriage?

Both miscarriage and stillbirth can be described as a loss of a pregnancy - we distinguish them based on when the loss happens.

  • Miscarriage describes a loss of a pregnancy that happened before the 20th gestation week.
  • We talk about stillbirth when a woman loses her baby after the first 20 weeks of the pregnancy or during the delivery.

💡 Stillbirth itself can be characterized as early, late, or term, depending on the [age of the pregnancy](calc:2194).

According to general statistics, the chances of having a stillborn are usually said to be 1 in 455. This number differs for different countries and regions:

  • 1 in 160 in the USA;
  • 1 in 250 in the UK; and
  • 1 in 121 in Latin America.

In reality, the odds of stillbirth are different for every single patient and depend on a variety of reasons, such as genetics, previous pregnancies, ethnicity, or history of substance abuse.

Our stillbirth risk calculator takes into account the following risk factors:

❗ The stillbirth calculator cannot be used as a substitute for clinical knowledge and/or consultation with a medical specialist. Always consult your doctor.

What are the causes of stillbirth?

There are multiple possible reasons for stillbirth:

  • Genetics;
  • Infections;
  • Maternal chronic diseases, such as lupus, clotting problems, hypertension, diabetes;
  • Preeclampsia and placenta problems; and
  • Mother's addictions and lifestyle choices.

How to prevent stillbirth?

There is no definite answer on how to prevent stillbirth — however, we can significantly lower the chances of having a stillborn by eliminating some of the risk factors:

  • Quit smoking;
  • Quit drinking alcohol;
  • Take care of proper treatment of hypertension, diabetes, or other chronic diseases; and
  • If your pre-pregnancy BMI is greater than or equal to 30, consider losing weight.

FAQ

What are the chances of stillbirth for a general population?

Chances of stillbirth in the USA are equal to 1:160. It means that statistically, 1 out of 160 pregnancies will end with stillbirth.

Worldwide, this number is even higher and reaches 1:72.
