Air Pollution Increases Insulin Resistance in Children


air-pollutionA study published in Diabetologica shows that long-term exposure to traffic-related air pollution is related to insulin resistance in children.

For the first time, this study indicates the possible association between air pollution and insulin resistance in children. One of the researchers commented, “although toxicity differs between air pollutants, they are all considered potent oxidisers that act either directly on lipids and proteins or indirectly through the activation of intracellular oxidant pathways”.

Oxidative stress is implicated in insulin resistance because it enables air pollutants to activate the devastating effects on cells in the body.

The fasting blood glucose of 397 10-year children were analyzed. Each child was assessed for the levels of exposure to traffic-related air pollution at their place of birth and environmental exposure.

In all models, estimated and calculated, the level of air pollution was directly related to the degree of insulin resistance in each child. The closer a child lived to the nearest major road increased insulin resistance. All the findings were statistically significant.

Clean air is healthy for you and nobody disputes the fact. All the cool kids are doing it: Jessica Alba, Drew Barrymore, Anne Hathaway, Leonardo Di Caprio, Brad Pitt, Matt Damon, and the list goes on. Distance your kids from traffic air pollution and you’ll distance your kids from insulin resistance.
