Previously connected to reproductive problems, a common chemical called phthalates is now being linked to abdominal obesity and insulin resistance in adult males, according to a new research finding from the University of Rochester Medical Center.

According to lead author Richard Stahlhut, M.D., M.P.H., a Preventive Medicine resident at the University of Rochester:

The research adds to the growing suspicion that low-dose exposures to phthalates and other common chemicals may be reducing testosterone levels or function in men, and thereby contributing to rising obesity rates and an epidemic of related disorders, such as Type 2 diabetes.

Found in a variety of products (from cosmetics, shampoos, soaps, lotions, lubricants, paint, pesticides, and plastics), phthalates can soften plastic tubing, PVC, and are also used in the coating of some timed-release medicines.

Study results have recently been published in the online edition of the journal Environmental Health Perspectives.
