Study Links Prenatal Phthalate Exposure to Reduced Childhood Lung Function

Introduction

Phthalates are a group of chemicals used in the production of plastics, personal care products, and other consumer goods. Exposure to phthalates during pregnancy has been linked to a range of adverse health outcomes in children, including asthma and other respiratory problems. A new study has found that prenatal exposure to phthalates may also be associated with reduced lung function in children.

What are Phthalates?

Phthalates are a group of chemicals that are used in the production of plastics, personal care products, and other consumer goods. They are added to plastics to make them more flexible and durable, and they are used in a wide range of products, including food packaging, toys, and medical devices. Phthalates are also used in personal care products, such as shampoos, lotions, and fragrances.

How are Phthalates Harmful?

Phthalates are known to be endocrine disruptors, which means that they can interfere with the body's hormonal system. Exposure to phthalates has been linked to a range of adverse health outcomes, including reproductive problems, developmental delays, and asthma. Phthalates have also been linked to reduced lung function in adults.

The Study

The new study, which was published in the journal Environmental Health Perspectives, looked at the relationship between prenatal exposure to phthalates and lung function in children. The study included 1,000 mother-child pairs from the United States and Canada. The researchers measured the levels of phthalates in the mothers' urine during pregnancy and then measured the children's lung function at age 6.

The Findings

The study found that prenatal exposure to certain types of phthalates was associated with reduced lung function in children. Specifically, the researchers found that exposure to di(2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DINP) was associated with reduced lung function. The researchers also found that exposure to DEHP was associated with an increased risk of asthma.

Conclusion

The findings of this study suggest that prenatal exposure to phthalates may be associated with reduced lung function in children. This is concerning, as reduced lung function can lead to a range of respiratory problems, including asthma. Pregnant women should take steps to reduce their exposure to phthalates by avoiding products that contain these chemicals, such as certain plastics and personal care products.
