Air pollution and industrial contaminants are emerging as significant contributors to osteoporosis, alongside traditional risk factors like poor diet and smoking.
Marta Zaraska reports for The Washington Post.
In short:
- Airborne particles such as PM2.5 and nitrogen oxides are linked to reduced bone density, particularly in postmenopausal women.
- Heavy metals like cadmium and lead, as well as "forever chemicals" like PFAS, accumulate in bones, impairing their strength and metabolism.
- Pollution can exacerbate bone loss through chronic inflammation, hormonal disruption and interference with vitamin D synthesis.
Key quote:
“Air pollution is a neglected risk factor for osteoporosis because for years we’ve focused on things like lifestyle factors, hormones and genetics.”
— Tuan Van Nguyen, professor of epidemiology at the University of New South Wales, Australia
Why this matters:
With aging populations and increasing pollution due to climate change, the prevalence of osteoporosis may grow, affecting millions. Understanding and mitigating these hidden risk factors could help preserve bone health, especially for vulnerable groups like postmenopausal women.
