Douching helps explain MEP disparities
In NHANES 2001–2004, frequent douching associated with 152% higher urinary MEP; Black women douched more and had higher MEP, linking a product-use pathway to exposure disparities.

Did Black women have higher metabolite concentrations?
Yes—significantly higher geometric mean MEP and MnBP than White or Mexican-American women.

What did authors conclude?
Douching may be a DEP source among frequent users and contribute to racial/ethnic DEP disparities.

Which survey years were used?
NHANES 2001–2004 reproductive-aged women.

Why are phthalates in douches a plausible exposure?
They are not chemically bound, so use can lead to dermal, inhalation, and ingestion exposure; metabolites have half-lives <24 h.

Was MnBP clearly associated with douching?
A positive association did not reach statistical significance.
