Women breathing high levels of pollution during the last month of pregnancy are more likely to give birth to babies with significantly lower weight as compared to an unexposed woman. A study of the effects of the air-quality controls, introduced during the 2008 Beijing Olympics, brings out the revelation.

Scientists involved in the study said that the temporary pollution regulations imposed on Beijing during 2008 Olympics had a measurable and positive effects on the weight of babies born to mothers who were 8-months pregnant at that time.

It is the first time when a study is able to indicate the harmful effects of air pollution on development of fetus in the womb while specifying the importance of clean air for fetal growth.

During 2008 Olympics, the Chinese government had imposed stringent curbs on vehicles and industry to minimize the impact of city’s high levels of air pollution on competing athletes. It was during this time when almost 84,000 births to mothers living in four urban districts of Beijing before, during and after the 2008 Olympics, were analyzed.

The study found that women who were in the eighth month of their pregnancy benefited most from the significantly “cleaner” air in the Chinese capital. The babies born to them were on average 23 grams heavier than the babies born to similar women in 2007 and 2009, when air pollution controls were not as severe.

David Rich, an epidemiologist at the University of Rochester Medical Centre in New York, and lead author of the study published in the journal Environmental Health Perspectives, said, “This is the first study to show that when air pollution levels go down during the 8th month of pregnancy, we see an increase in birth weight.”

Just before the Olympics, the Chinese government took many steps to bring down the high pollution level in the capital. They prohibited traffic, closed factories and even seeded clouds to make it rain. These measures together led to 60% reduction in sulfur dioxide, 48% reduction in carbon monoxide, 43% reduction in nitrogen dioxide and a reduction in the number of particles in the air smaller than 2.5 microns, which have the capability to enter the blood stream through the lungs.

“The results of this study demonstrate a clear association between changes in air pollutant concentrations and birth weight. These findings not only illustrate one of the many significant health consequences of pollution, but also demonstrate that this phenomenon can be reversed,” said Dr. Rich.

“While Beijing’s pollution is particularly noteworthy, many of the world’s other cities face similar air-quality problems. This study shows that pollution controls – even short-term ones – can have positive public health benefits,” said Junfeng Zhang, a researcher at Duke University in North Carolina, who led the study.

Tokyo Olympics 2020 Indian wrestler Ravi Kumar enter semi finals.

Indian wrestler Ravi Kumar (57kg) and Deepak Punia (86kg) enjoyed fruitful outings at the Tokyo Olympic Games as they secured semifinal berths in their respective weight categories at the Makuhari Messe on Wednesday.

On the opening day of the wrestling competition, Ravi Kumar defeated Bulgaria's Georgi Vangelov 14-4 on technical superiority to reach the last-four in the men's 57kg category, while compatriot Deepak Punia overcame China's Zushen Lin 6-3 on points to advance to the semifinals.

Ravi Kumar will take on Nurislam Sanayev of Kazakhstan in the last-four, while Punia will be up against David Morris Taylor of the USA.

Earlier, Ravi Kumar had won his opening-round bout by technical superiority against Colombia's Oscar Tigreros to secure a quarterfinal spot. Competing in the Round-of-16 bout against the Colombian wrestler, the 23-year-old Ravi Kumar, who is making his Olympic debut, showed no nerves as he dominated the bout to win by technical superiority (13-2).

Ravi Kumar landed attack after attack and went 13-2 up, winning the bout by technical superiority with minutes to spare. In wrestling, building up a 10-point lead over the opponent results in a victory by technical superiority.

India's 86kg freestyle wrestler Deepak Punia showed no signs of the niggle that had forced him to pull out of the Poland Open Ranking Series in Warsaw in June, as he defeated Nigeria's Ekerekeme Agiomor on technical superiority to secure a quarterfinal berth.

He got his Olympic campaign to a fine start as he was in control from the start of the bout and hardly ever allowed his Nigerian opponent any room to maneuver his moves, finally winning with a 12-1 on technical superiority.

Punia, who had also suffered an elbow injury just before the Games, was slow at the start but came into his own as the bout progressed, inflicting takedowns at regular intervals to earn points.

The Indian wrestler eased into a 4-1 lead at the break and extended his lead comfortably in the second period.

Punia, the silver medallist from the 2019 world wrestling championships, then set up a clash with China's Lin Zushen in the quarterfinals and defeated him 6-3.
