New Study Finds that Air Pollution is Making Human Bones More Brittle

The recent results of a long-term experiment have revealed a correlation between exposure to air pollution and rapid deterioration of bone strength and density in menopausal women.

Osteoporosis affects an estimated 10 million Americans, with approximately 2.1 million osteoporosis-related bone fractures resulting in an impact of upwards of $20 billion on the American healthcare system each year. Osteoporosis is more likely to affect women, and postmenopausal women are at the greatest risk, with half of the women over fifty experiencing a bone fracture as a result of osteoporosis.

Though it is widely known that air pollution exposure can cause severe and sometimes life-threatening health complications in respiratory and cardiovascular symptoms, many of the other health effects of air pollution fly under the radar.

The study was published in the peer-reviewed, open-access journal eClinicalMedicine, which is part of The Lancet Discovery Science.

161,808 postmenopausal women from various ethnic backgrounds participated in the Women’s Health Initiative survey, which provided the researchers with data for their analysis. Based on the participants’ residential locations, they calculated their exposure to air pollution (PM10, NO, NO2, and SO2). Using dual-energy X-ray absorptiometry, they assessed bone mineral density (BMD; whole-body, total hip, femoral neck, and lumbar spine) at registration and follow-up at years one, three, and six.

The study revealed a...
