Tuesday, 2021 June 15 (HealthDay News) – Researchers say babies may increase their risk of obesity if their mothers are exposed to high levels of air pollution during pregnancy.
In a new study, 123 Hispanic couples were involved in a lawsuit in the Los Angeles area. Before pregnancy, about one-third of mothers were normal weight, one-third were overweight, and one-third were obese.
Researchers at Boulder University in Colorado analyzed data from the US Environmental Protection Agency on air pollution during pregnancy and assessed their newborns.
Newborns whose mothers were exposed to higher levels of air pollution during pregnancy grew unusually fast in their first six months, gaining excess fat, which puts them at risk for obesity and related diseases, according to the study.
Specific contaminants seemed to affect male and female infants in different ways.
For example, the effect of a combination of ozone and nitrogen dioxide in the uterus was associated with faster waist growth in women. But this was due to the slow increase in length ավելի in middle-aged men with a greater accumulation of fat.
According to the authors of the study, in adults, excess fat around the waist is associated with heart disease – diabetes. The results were published online in the June 5 issue of the journal Environmental health,
This is the latest study to suggest that poor air quality may play a role in the US obesity epidemic, particularly among minority groups who tend to live in areas most exposed to toxic pollutants.
One in four Hispanic youth in the United States is obese, compared with about 14% of white youth and 11% of Asian youth.
“Higher levels of obesity in certain groups of our society are not just a by-product of personal choice, such as exercise – calories, calories. “It’s more complicated,” said Tanya Aldereete, the study’s lead author.
“This study, other studies suggest that it may be related to how much the environment bears,” said Alderete, an assistant physiologist in integrative physiology.
Pregnant women should try to minimize the effects of air pollution by closing their windows on high ozone days, not exercising outdoors when air pollution levels are high, and avoiding parallel exercise on busy roads, the study authors recommend.
