Air pollution could cause brittle bone disease, according to new research. The study linked pollution exposure to low levels of parathyroid hormone, which regulates calcium production, leading to weaker bones and more hospitalizations for fractures. Smog-filled towns and cities have been linked to an increased risk of stroke, heart disease, lung cancer, acute respiratory diseases such as asthma and dementia.
The pollutant particle was linked to higher levels of parathyroid hormone, a small rise in PM2.5 concentrations would lead to an increase in bone fractures in older adults. Those living in areas high in PM2.5 and black carbon from heavy traffic had lower levels of parathyroid hormone, which is key to building calcium, and less bone mineral density than others exposed to less of the pollutants.
Osteoporosis, the most common reason for a broken bone among the elderly, is a disease in which bones become brittle and weak as the body loses more bone mass than it can rebuild. Particulate matter, including PM2.5, is known to cause systemic oxidative damage and inflammation, which they suggest, could accelerate bone loss and increase risk of bone fractures in older individuals. Smoking which contains several particulate matter components has been consistently associated with bone damage.
Within a year of a bone fracture, death risks for older individuals increase by up to 20 percent, with only 40 percent regaining full independence. Vitamin B can reduce pollution fueled cardiovascular disease, and damage to DNA. The best way to prevent air-pollution-related diseases is through policies to improve air quality. Air pollution is considered the most important risk factor for mortality at the population level, it is also a risk factor for osteoporosis.
