News from ISGlobal
Some of the effects of air pollution on health are well documented – lung cancer, stroke, respiratory diseases, and a long etcetera – but for others there is less scientific evidence. Such is the case of bone health: there are only a few studies and results are inconclusive. Now, a study in India led by the Barcelona Institute for Global Health (ISGlobal) has found an association between exposure to air pollution and poor bone health.
Osteoporosis is a disease in which the density and quality of the bone is reduced. Globally, it is responsible for a substantial burden of disease and its prevalence is expected to increase due to aging of the population.
The new study performed by the CHAI Project, led by ISGlobal, analysed the association between air pollution and bone health in over 3,700 people from 28 villages outside the city of Hyderabad, in southern India.
The results showed that exposure to ambient air pollution, particularly to fine particles, was associated with lower levels of bone mass. No correlation was found with use of biomass fuel for cooking.
