Hormonal

Higher urinary concentrations of MEHP (a metabolite of DEHP) are inversely associated with BMI and waist circumference in adolescent and adult females, suggesting a complex, potentially anti-androgenic or metabolic effect distinct from males.

For women, the relationship between phthalate exposure (specifically DEHP metabolites) and weight is complex and potentially inverse, unlike in men. This highlights the importance of considering hormonal context when evaluating environmental health risks.

MEHP was inversely related to BMI and WC in adolescent and adult females... Mean BMI generally decreased across quartiles among adolescent girls... and among 20–59 year old females.

Cross-sectional observational study; association is clear but mechanism is speculative.
