Maternal Bipolar Disorder Significantly Increases Risk for Premature Births

Premature babies–infants born before the 37th week of pregnancy–endure a great number of challenges, such as high blood pressure, hypoglycemia, and breathing properly. No one wants their baby to be born early, unless there’s a risk to the mother.

But, unfortunately for mothers with severe bipolar disorder, they may not have a choice. A 2015 study published in the American Journal of Obstetrics and Gynecology showed that mothers with bipolar disorder are twice as likely to give birth prematurely than mothers with no mental illnesses. And a 2010 study published in the Journal of Affective Disorders demonstrated that in Taiwan, the incidence rate of premature births among pregnant women with bipolar disorder was 14.2%, compared to 6.9% of women without mental illnesses. The Taiwan study also included statistics about infants with low birth weights (9.8% vs. 5.7%), and smaller-than-gestational-age babies (22.3% vs. 15.7%).

Unfortunately, premature babies are also 2.7 times more likely than full-term babies to develop bipolar disorder later in life. For a full breakdown of these statistics, including the risk for psychosis and schizophrenia, click here.

But it’s not all bad news. The rates of premature births for bipolar mothers aren’t very high. A 14.2% chance to have a preterm baby means that you have an 85.8% chance to have a full-term baby. That’s pretty good!

So what can you do to prevent preterm births? The risk factors for a premature infant include:

  • Already having had a premature baby. This is a major risk factor.
  • A second pregnancy soon after having a baby.
  • Being pregnant with twins or more.
  • Having uterine or cervix problems.
  • Being overweight or underweight.
  • High blood pressure, stress, diabetes, and some infections.
  • Smoking and substance use.
  • Becoming ill with the flu.

Some of these things you can’t control, like having twins. But others, you can, such as avoiding pregnancy soon after having a baby, stopping substance use, or getting your flu shot. Maintaining a healthy weight during pregnancy also helps, so be sure to exercise and eat a healthy diet.

Final Thoughts

Premature birth can be scary and challenging. But, while the likelihood of giving birth prematurely is increased for bipolar mothers, the overall rate isn’t that high. Follow your obstetrician’s advice. There are some steps you can take in order to hopefully prevent a preterm infant.

Good luck!

    1. Dearest Dyane, my wonderful PR agent and dear friend,

      Thank you so much for your constant encouragement! I really appreciate your support, and trust me, it’s not nagging! I have written a different post for the IBPF, which for now is a secret, but it’s near and dear to my heart. They told me they would email me with the guidelines a couple of weeks ago, and just haven’t gotten around to it. I will email them soon, today or tomorrow. Thanks for the impetus! Take care of yourself and hopefully I’ll be seeing a blog post of yours soon!

      Love,
      Cass
