Osteoporosis affects millions of people around the world, and some of the main risk factors that cause disease, such as aging, cannot be changed. However, environmental risk factors are increasing, as air pollution appears to be one of the causes of fragile disease, according to the results of a study published by the Medical Daily News.
Osteoporosis or osteoporosis is a condition in which the patient suffers from weak bone density, which makes it dry and brittle. This condition tends to affect older individuals, especially females. And scientific studies have revealed that some factors – such as vitamin D deficiency – can also contribute to the development of the disease. And with continued scientific research into the causes and strategies for optimal prevention against this disease, scientists have come up with other possible environmental causes, which we list below.
A new study by the Barcelona Institute of Global Health, whose findings are published in the journal JAMA Network Open, indicates that poor air quality is associated with low bone density among the elderly.
“The results of this study contribute as a first step towards resolving the relationship between air pollution and bone health,” says lead researcher Professor Otavio Razanjani.
The researchers analyzed data on bone health and living conditions for 3,717 participants, including 1711 women, from 28 villages near Hyderabad in India.
Carbon and fine particles
The researchers used estimates of external exposure to air pollution, to indicate the presence of carbon and fine particles in the air, which come, for example, from car exhaust. These molecules remain airborne for a long time and infiltrate the human body through the lungs.
The researchers also took into account data, collected through self-help efforts, through questionnaires of participants about the type of fuel they use when cooking.
The study found that individuals, who often suffered from ambient air pollution, especially by micro-particles, also appeared to be those with low bone mass.
Oxidative stress and infections

Ransani assumes that the relationship between poor air quality and poor bone health can be due to “oxidative stress and infections caused by air pollution”.
The researchers also noted that the exposure of the participants to airborne fine particles is 32.8 micrograms per cubic meter per year, which far exceeds the limits recommended by the World Health Organization, which amounts to 10 micrograms per cubic meter.
In rich and poor countries
“The results of the study add to a set of evidence that indicates particulate air pollution negatively affects bone health across a wide range of levels of air pollution, including levels in high-income and low- and middle-income countries,” says researcher participating in the study, Dr. Catherine Ton.
