Plastic pollution could be the silent cause of premature births? Startling new research shares insights ByHT Lifestyle Desk | Edited by Zarafshan Shiraz, New Delhi Feb 02, 2025 06:14 PM IST Read this news in brief form Share Via Copy Link The plastic problem no one saw coming—Could it be causing premature births?

A groundbreaking study has uncovered a startling link between microplastic pollution and premature births, sparking fresh concerns over how these tiny particles may be affecting human health. Researchers found significantly higher levels of microplastics and nanoplastics in the placentas of preterm births compared to those of full-term pregnancies.

The research, presented at the Society for Maternal-Fetal Medicine’s annual meeting in Denver, raised urgent questions about the role of plastic pollution in pregnancy complications.

Microplastics—minute plastic fragments resulting from the breakdown of plastic waste—have infiltrated every corner of our planet where from the peaks of Mount Everest to the deepest oceans, these particles are now a part of our environment. They are consumed through food, water, and even inhaled from the air we breathe but their presence in the human body, particularly in critical organs like the placenta, is an alarming revelation.

The study, conducted in Houston, analyzed 175 placentas—100 from full-term births (averaging 37.2 weeks) and 75 from preterm births (averaging 34 weeks). Researchers discovered an average of 203 micrograms of plastic per gram of tissue (µg/g) in preterm placentas, over 50% more than the 130µg/g found in full-term placentas.

The presence of common plastics like PET (used in plastic bottles), PVC, polyurethane, and polycarbonate suggested that environmental exposure plays a significant role.

While it might be expected that longer pregnancies would lead to more plastic accumulation, the opposite proved true. The shorter gestational periods had higher microplastic levels, a finding that left researchers stunned. “This was a big surprise,” said Dr Enrico Barrozo of Baylor College of Medicine, one of the study’s lead researchers.

The reason for two-thirds of preterm births remains unknown, making this study a crucial step in identifying potential environmental risk factors. Previous research has already linked air pollution to millions of premature births, prompting scientists to investigate whether microplastics could be contributing to this global issue.

Although the study only establishes a correlation—not a direct cause—between microplastics and premature births, the implications are troubling. Microplastics are known to cause inflammation in human cells and inflammation is a key trigger for labour so, could this be why pregnancies exposed to higher plastic levels end earlier?

The study added to a growing body of research on microplastics in the human body. Since their first detection in placentas in 2020, microplastics have also been found in semen, breast milk, brains, livers and bone marrow.

Some studies have linked them to strokes and heart attacks, suggesting they may be more than just environmental pollutants—they could be silent contributors to serious health conditions.

Professor Kjersti Aagaard of Boston Children’s Hospital emphasised the importance of raising awareness and said, “Our study hints at the possibility that the accumulation of plastics could be contributing to preterm birth. Combined with other recent research, this study adds to the growing evidence that plastic exposure poses real risks to human health.”

While the findings are alarming, they also highlight the urgent need for further research and scientists are now calling for studies to determine whether reducing plastic exposure can lower the risk of preterm births. From policy changes to personal lifestyle adjustments, actions to limit plastic exposure may soon become a major public health priority.

As we continue to uncover the hidden dangers of microplastics, one thing is clear: these tiny particles are making a massive impact. For expectant mothers and those planning to conceive, awareness is the first step toward protection.

Could avoiding plastics be the next big step in prenatal care? Only time—and more research—will tell.
