Prenatal exposure to air pollution and climatic agents associated with adverse births in India

Prenatal exposure to particles and climatic agents, such as temperature and rainfall, are associated with adverse births in India, according to a study published on July 2, 2025, in open access magazine Plos Global Public Health by Mary Abed Al Ahad from the University of St. Andrew in the United Kingdom

Air pollution of the environment is a global threat to human health, with a disproportionate burden of damaging effects that fall on those living in low and medium -income countries. It is referred to as a silent killer, air pollution is one of the first five risk factors for mortality in both men and females. With a diameter of less than 2.5 small, the environment of fine 2.5 (PM2.5), which derives mainly from the burning of fossil fuels and biomass, is considered the most harmful atmospheric pollution. At the 2023 World Air Quality Exhibition, India was ranked as the third most polluted country of 134 nations based on annual PM2.5 levels.

Atmospheric air pollution has been associated with a series of pediatric morbidity, including adverse birth effects, asthma, cancer and an increased risk of chronic diseases. Most studies investigating the association between air pollution and negative births have been mainly carried out in high -income countries. Despite the worrying increase in levels of air pollution in India, there has been a lack of research that investigates its impact on the negative effects of birth.

To cope with this gap, researchers investigated the impact of ambient ambient pollution on negative birth effects at national level, focusing on low birth weight and premature birth and using different geospatial models to highlight vulnerable areas. The analysis provided data on the correlation between the intero exposure to PM2.5 and the adverse effects of birth, utilizing satellite data and large -scale research data. Individual analysis revealed that the increase in the PM2.5 environment is linked to a greater chance of low birth weight and premature birth. Climate factors such as rainfall and temperature were also associated with the negative effects of birth. Children living in the northern regions of India appear to be more sensitive to the adverse effects of ambient pollution of the environment.

According to the authors, geostation analysis emphasizes the need for targeted interventions, especially in the northern regions. In addition, the national fresh air program should be intensified, with stricter emissions and enhanced air quality monitoring. Climate adjustment strategies, such as the development of thermal action plans and improving water management, should be incorporated into public health planning to alleviate the effects of extreme temperatures and irregular rainfall. Public Health Initiatives should be implemented to raise awareness of air pollution and climate change, especially among pregnant women.
