Obesity is a condition that involves a series of disadvantages. From an aesthetic point of view to health related problems, excess of weight is something should always be avoided. According to a study made from the Université de Montréal’s School of Public Health, overweight persons are more exposed to pollution effects up to 50% more than normal-weight persons.
The same situation is true for children, whose rates of exposure to pollutants range from 10 to 24 %. The study examines the obese class 2, those with a BMI range from 35 to 39.9.
According to dr. Pierre Brochu, one of the doctors who take part to the study, those people inhale every day 24.5 cubic feet of air, about 8.2 cubic meters more than an adult who is not obese. About 50% of the air inhaled is made by pollutants, such as ammonia, sulfur dioxide, ozone and nitrogen dioxide. In addition to the known consequences of pollution, most notably cancer, these agents are irritants for respiratory and can cause a range of other diseases.
The study analyzed 1900 volunteers between the ages of 5 and 96 for more than a decade, and noted how, through the analysis of blood and urine, he has confirmed the theory that the greater the weight, the greater the amount of contaminants circulating in the body.
The situation is even more risky if a child is involved, as they have an accelerated metabolism and inhaled pollution can spread quicker in the body.
The question that now Dr. Brochu wants to find out an answer is whether this factor can lead to respiratory diseases such as asthma or lung diseases.
