GTB Hospital studying impact of air pollution on unborn child

Air pollution may not just lead to respiratory problems, but could also be a leading cause of premature delivery and low birth rate, according to experts.

Guru Teg Bahadur Hospital (GTB Hospital), Delhi, is conducting a research to study the impact of air pollution on foetus.

"It has been seen that exposure of pregnant women to high level of air pollution sometimes leads to premature delivery or affects the birth rate as well. It is not yet substantiated, however, that pollution will cause any type of congenital malformation. The result of the study will help us get a clearer picture," Kiran Guleria, a gynaecologist at the GTB Hospital, told IANS.

She is a part of the research and working at the Department of Biochemistry in the city-based University College of Medical Sciences.

The research is a part of the study titled "DAPHNE" (Delhi Air Pollution Health And Effects), where the All-India Institute of Medical Sciences (AIIMS) is also doing a project related to the effect of pollution on children with respiratory problems.

Guleria said that the research primarily focuses on monitoring the foetus and the unborn child, which will involve observing the baby in the womb and mapping its growth.

"The study will help us understand and see the effect of pollution on the unborn child in terms of growth, respiratory problems like asthma or other allergies. After birth, the child will also be observed for two years," the health expert noted.

For the study, a belt has been developed that will be worn by women for 48 hours during each trimester of pregnancy. There will be a continuous mapping of the women involved in the project for 9 months.

"It will give a clear picture on the impact of pollution during different seasons as well. Simultaneously, we will collect blood and urine samples to understand it better. After the child is born, we will even examine the cord blood to see how much transition of air pollution has happened from the mother to child," Guleria added.

GTB Hospital has already started recruiting patients for the project. women aged between 20 and 35 with no other pregnancy complications have been approached by the research team.

Funded by the Department of Biotechnology, Ministry of Science and Technology, India, and Medical Research Council, Britain, the project is a collaborative effort of the two nations.

In India, apart from the GTB Hospital and AIIMS, Sri Ramachandra University, Chennai, and IIT Delhi are also associated with the research.
