Stillbirth Risk Calculator
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:
- Mother's age and ethnicity;
- BMI (Body Mass Index) and the pre-pregnancy weight;
- Previous obstetric history and the use of ISCI/IVF;
- Presence of diabetes or hypertension;
- Autoimmune diseases, such as lupus or anti-phospholipid syndrome (increased risk of blood clots); and
- Use of alcohol and tobacco during pregnancy.
How to calculate the risk of stillbirth?
Look here for a quick explanation of the work of our stillbirth risk calculator.
- For the baseline risk, we used the percentage of stillbirths for the general population of the USA.
- We choose to calculate the collective risk using the odds and risk ratios taken from the National Institute of Health's research, CDC records, and a few other peer-reviewed articles, available here.
|❗ 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:
- 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.
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.
