Physical disabilities in senior citizens could have direct link to pollution: Study
physical disabilities, especially among elders, leading to difficulties in performing activities of daily living (ADL), reported TOI.
The study was conducted in the US with 15,411 participants over an average follow-up period of about eight years. It found that at least 48 per cent of the participants aged 65 years and above reported new difficulties in performing daily activities due to exposure to pollution.
The researchers discovered that higher concentrations of particulate matter (PM2.5 and PM10-2.5) and nitrogen dioxide (NO2) were associated with increased risks of ADL disability. However, not all associations reached statistical significance. Moreover, ozone (O3) was found to be associated with a lower risk of ADL disability.
«The results of our study indicate that exposure to air pollution may be a significant, yet often overlooked, contributor to the development of physical limitations in older individuals. However, further investigations are necessary to confirm and expand upon these initial findings,» stated the researchers.
