Exposure to fine particulate matter (PM2.5) air pollution can lead to higher inflammation levels among pregnant women, potentially resulting in adverse birth outcomes such as low birth weight and preterm birth. This is according to a recent study published in the journal Science Advances, which examined how pollution alters human DNA.
The study, led by Harvard University's School of Public Health, found that PM2.5 exposure can influence the histones of pregnant women, disrupting the normal balance of cytokine genes and leading to increased inflammation in both women and fetuses.
Sources of PM2.5 pollution
PM2.5 pollution is caused by particles sized 2.5 micrometres or less, commonly emitted by vehicles and industrial activities. Natural sources include carbon from wildfires and dust.
Key findings of the study
1. Exposure to PM2.5 can lead to increased inflammation in pregnant women, potentially resulting in adverse birth outcomes.
2. PM2.5 exposure can disrupt the normal balance of cytokine genes, leading to increased inflammation in both women and fetuses.
3. The study highlights the importance of minimizing air pollution exposure in pregnant women to protect maternal and fetal health.
Reducing exposure to PM2.5 pollution
To minimize exposure to PM2.5 pollution, pregnant women can take several steps:
1. Avoid heavily polluted areas, especially during peak traffic hours.
2. Use air purifiers to reduce indoor pollution levels.
3. Wear masks when outdoors in polluted areas.
4. Support policy interventions to improve air quality and reduce pollution levels.
By taking these steps, pregnant women can reduce their exposure to PM2.5 pollution and minimize the risk of adverse birth outcomes.
