Pregnant mice exposed to high levels of air pollution gave birth to offspring with a significantly higher rate of obesity and insulin resistance in adulthood than those that were not exposed to air pollution. This effect seemed especially prevalent in male mice, which were heavier regardless of diet. These findings, published online in the FASEB Journal, suggests a link between diesel exhaust exposure in utero and bulging waistlines in adulthood.
They found that males from diesel-exposed moms were heavier than the males from clean air-exposed moms regardless of their diet as adults. In contrast, females from diesel-exposed moms were heavier than control females only if they were fed a high-fat diet as adults, and they never developed signs of insulin resistance.
