A recent study has revealed that a chemical used in many everyday products has contributed to approximately 2 million premature births globally. This substance, known as di-2-ethylhexyl phthalate (DEHP), is found in cosmetics, detergents, and pesticides, making it a part of our daily lives.
This chemical raises numerous health concerns, having previously been linked to diseases such as cancer, heart disease, and infertility. The study conducted by researchers from NYU Langone Health highlights the impact of this substance on premature births, as births occurring before the 37th week of pregnancy are a leading cause of infant mortality.
Details of the Findings
The study estimates that DEHP contributed to around 1.97 million premature births in 2018, resulting in the deaths of about 74,000 infants worldwide. Scientists believe that phthalates like DEHP may increase the risk of premature birth by affecting hormones that regulate pregnancy, leading to inflammation and stress in the placenta.
While the exact mechanisms are still under investigation, these chemicals are known to disrupt endocrine functions, which can affect fetal development. The World Health Organization indicates that children born before the 37th week of pregnancy face higher risks in learning and long-term development.
Background & Context
Historically, previous studies have linked phthalate exposure to premature births, but most evidence came from small or regional studies. This new research is the first to estimate the global burden, combining exposure data and health outcomes across more than 200 countries.
The results show that the impact of this chemical is not evenly distributed. The Middle East and South Asia bear more than half of the global burden associated with DEHP exposure, as rapid industrialization and increased plastic use lead to higher levels of exposure. In Africa, the picture is even clearer: despite lower recorded cases, newborns there are more likely to die, reflecting gaps in access to healthcare.
Impact & Consequences
The study suggests a dual burden, where high environmental risks collide with weaker health systems, exacerbating the impact in already vulnerable areas. In addition to health risks, the study raises questions about how chemicals are regulated. Phthalates are often treated individually, but the analysis suggests that alternative substances may carry similar risks.
For instance, DBP, a common substitute for DEHP, has been found to pose similar risks, raising concerns about replacing one harmful substance with another. Dr. Leonardo Trasande, the lead author of the study, noted that these findings highlight the urgent need for stronger regulations on plastic additives to avoid repeating past mistakes.
Regional Significance
In the Arab region, where many countries are witnessing an increase in plastic use, these findings raise serious public health concerns. The current situation necessitates intensified efforts to monitor the chemicals used in everyday products and to strengthen healthcare systems to address potential risks.
This study serves as a call to reconsider how chemicals are regulated in consumer products, requiring international and regional cooperation to ensure the safety of citizens.
