Investigation on the Combined Effects of Genetic Factors and Air Pollution Exposure on Atrial Fibrillation Risk
Investigators in China have conducted a study to examine the impact of genetic factors and long-term air pollution exposure on the risk of atrial fibrillation (AF). The study, published in the Proceedings of the National Academy of Sciences, included 401,251 participants without AF at baseline from the UK Biobank. The researchers estimated the participants’ exposure to air pollutants, such as PM2.5, PM10, NO2, and NOx, based on their residential addresses.
Genetic Data and Risk Score Calculation
The genetic data of the participants was obtained from the UK Biobank. Using this data, the researchers constructed a polygenic risk score for AF. This score helped assess the genetic risk of each participant for developing AF.
Association between Air Pollution and AF Risk
The study revealed that long-term exposure to air pollutants was associated with an increased risk of AF. The specific air pollutants considered in the study were PM2.5, PM10, NO2, and NOx.
Additive Effects of Genetic Risk and Air Pollutants
Furthermore, the researchers found that the combined effects of genetic risk and air pollutants had an additive effect on AF risk. Approximately 16 percent to 35 percent of AF risk could be explained by the additive effects of co-exposure to high air pollutants and high genetic risk.
Implications for Sustainable Development Goals (SDGs)
The findings of this study emphasize the importance of improving air quality for the entire population, particularly for individuals with high levels of genetic risk. By reducing air pollution, we can potentially prevent a significant proportion of AF cases. This has significant implications for the primary prevention of AF and aligns with the Sustainable Development Goals (SDGs), specifically Goal 3: Good Health and Well-being.
SDGs, Targets, and Indicators
1. Which SDGs are addressed or connected to the issues highlighted in the article?
- SDG 3: Good Health and Well-being
- SDG 11: Sustainable Cities and Communities
The article discusses the impact of air pollution on atrial fibrillation (AF) risk, which is related to the goal of promoting good health and well-being (SDG 3). Additionally, it highlights the need to improve air quality, which is connected to creating sustainable cities and communities (SDG 11).
2. What specific targets under those SDGs can be identified based on the article’s content?
- Target 3.9: By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water, and soil pollution and contamination.
- Target 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management.
The article emphasizes the need to reduce the risk of AF by improving air quality, aligning with Target 3.9 of SDG 3. It also highlights the importance of addressing air pollution as part of creating sustainable cities, which corresponds to Target 11.6 of SDG 11.
3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?
Yes, there are indicators mentioned in the article that can be used to measure progress towards the identified targets. These indicators include:
- Air pollutant exposure levels (PM2.5, PM10, NO2, and NOx) at residential addresses
- Genetic risk score for atrial fibrillation
- Percentage of AF risk explained by the additive effects of co-exposure to high air pollutants and high genetic risk
These indicators can be used to assess the reduction in air pollutant exposure levels, the impact of genetic factors on AF risk, and the effectiveness of interventions in reducing AF risk associated with air pollution.
