Air pollution has worse effects on the bone density of postmenopausal women

A study conducted at Columbia University's Mailman School of Public Health found that air pollution has a negative effect on the bone density of postmenopausal women. 

Even though studies on effects of air pollution on human bones have been done earlier, it was done for the first time on effects of air pollution on the bone density of postmenopausal women. 

This study was published in the e-Clinical Medicine Journal. The team used data from the Women's health initiative study, which was conducted on 1,61,808 postmenopausal women. 

Scientists measured bone mineral density at the beginning of the experiment and then followed-up after one year, three years and six years using dual energy X-rays. 
It was concluded that the spinal cord of postmenopausal women was the most damaged and the major reason behind it was nitrous oxide.
