A recent study suggests that chemicals commonly found in plastics and cosmetics may be linked to an increased risk of preterm birth, potentially affecting thousands of births each year in the United States.
The research, conducted by a team from Bond University and Griffith University in Australia, analyzed data from over 5,000 pregnant women in the U.S. The findings indicate that exposure to phthalates, which are widely used in personal care products and food packaging, may contribute to an elevated risk of premature birth and lower birth weight.
While the study observed a correlation between the concentration of phthalate breakdown products in maternal urine and adverse pregnancy outcomes, it did not establish a direct causal relationship. However, researchers emphasize the significance of these findings, particularly given the potential health implications of shortened pregnancies.
Dr. Leonardo Trasande, lead author of the study and a professor of pediatrics at NYU Langone Health, highlights the importance of understanding the consequences of even minor shifts in gestation duration. He notes that a shift from a full-term pregnancy to preterm birth, even by a few days or a week, can have substantial impacts on both cognitive development and healthcare costs.
According to estimates from the study, the additional medical expenses and lost economic productivity associated with preterm birth could amount to billions of dollars over the affected children’s lifetimes.
Phthalates have long been of interest to researchers due to their potential to disrupt hormonal activity and increase inflammation. While exposure to these chemicals can occur through various routes, including ingestion and inhalation, their presence in everyday products raises concerns about widespread exposure.
Despite the growing body of evidence linking phthalates to adverse health effects, federal regulations on labeling and product safety remain limited. Dr. Sophie Balk, a professor of pediatrics at the Albert Einstein College of Medicine, underscores the importance of consumer awareness in minimizing exposure to phthalates and similar chemicals.
While some phthalates have been restricted in certain products, they continue to be used extensively in personal care items and food packaging. Dr. Balk advises consumers to scrutinize product labels for ingredients like “fragrance” or “parfum” and opt for fresh foods over packaged ones. Additionally, avoiding the use of plastic containers for microwaving food can help reduce exposure.
In conclusion, while further research is needed to fully understand the impact of phthalates on pregnancy outcomes, the study highlights the potential health risks associated with these ubiquitous chemicals. Increased awareness and informed consumer choices may play a crucial role in mitigating these risks and promoting maternal and infant health.
