As the issue of air pollution has gradually received more attention in recent years, more studies have begun to find that air pollution has significant harm to human health. Among them, the impact of respiratory-related diseases is well known (such as lung cancer, asthma, lung function low, etc.), but in fact the impact of air pollution is far more than these, such as cardiovascular disease, low birth weight, premature birth and death, etc. are gradually discovered health hazards, and what I want to share this time is air pollution Another significant health risk of:Osteoporosis.
The impact of air pollution on osteoporosis has been gradually discovered in recent years and has been repeatedly confirmed in multiple studies. In 2023, a new study was published in the heavyweight journal "eClinicalMedicine"paper, and especially targeted at high-risk groups for osteoporosis─postmenopausal womenLet’s discuss. Let me explain it to you below:
This is the first research paper to explore the detailed relationship between air pollution and bone mineral density (BMD) in postmenopausal women. The research team used the database of the Women's Health Initiative Study conducted by the National Institutes of Health to collect data on 161,808 postmenopausal women from 40 clinical medical centers between 1993 and 1998. According to the participants' residence, Air pollution exposure dose (coarse aerosol particles PM) was estimated using historical data from the U.S. Environmental Protection Agency10, nitric oxide NO, nitrogen dioxide NO2, sulfur dioxide SO2), and in the first, third and sixth years of follow-up, the bone density of the participants' whole body, lumbar spine, hip and femoral neck was measured with a dual-energy X-ray absorptiometer.
After statistical analysis, the research team found that the impact of aging is different on bone density in different parts, with the hip and femoral neck having the greatest impact (hip, femoral neck, whole body, and lumbar spine, respectively, decrease by 0.64%, 0.59%, 0.35%, 0.18%); however,The impact of nitrogen oxides in air pollutants on the bone density of the lumbar spine is about an additional 1.22% per year, which is almost twice the average impact of aging. If compared with the impact of aging on the lumbar spine, it is even closer. 7x the impact.
Overall, worse air pollution is associated with bone loss in postmenopausal women, with the most severe impact on lumbar spine bone density. Among the four air pollution indicators, the highestNitrogen oxides have the most significant impact on bone loss.
In Taiwan, air quality varies from place to place, but air pollution persists (please refer toAir Quality Monitoring Network), so the author suggests that in addition to paying attention to outdoor air quality at all times,PurchaseYou should also use a suitable air purifier and maintain good eating and exercise habits in your life (please refer toThis article), in order to prevent yourself from becoming the next osteoporosis patient!
