Hypothesis
Exposure to phthalates during pregnancy negatively affects newborn growth and development.
Conclusion
The study found that exposure to certain phthalates during pregnancy can adversely affect newborn birth weight, length, and gestational age.
Supporting Evidence
- 497 pregnant women were found to be widely exposed to phthalates.
- Monobutyl phthalate (MBP) had the highest median level of 104.46 ng/mL.
- Linear regression showed that each natural log increase in monoethyl phthalate (MEP) levels decreased gestational age by 0.11 weeks.
- Each natural log increase in mono(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono(2-ethylhexyl) phthalate (MECPP) levels decreased birth weight by 39.28 g and 39.62 g, respectively.
Takeaway
Pregnant women can have chemicals in their bodies that might hurt their babies, and this study looked at how those chemicals affect baby growth.
Methodology
The study developed a method using solid-phase extraction and high-performance liquid chromatography-tandem mass spectrometry to detect eight phthalate metabolites in urine samples from pregnant women.
Limitations
Further large-scale cohort studies are needed to validate these findings.
