Traffic noise increases the risk of obesity

Traffic noise increases the risk of obesity, not just sitting in the car for several hours before it gets to work.

A new study shows how traffic noise increases the risk of obesity.

It is real that we live in a cosmopolitan city full of polluting cars not only emphasizes us, but it can make us fat.

It appears that long-term exposure to noise from cars, trucks and motorcycles is linked to the possibility of obesity.

The study was conducted at the Institute of Global Health in Barcelona and the Banca la Caixa Foundation and published in the journal Environment International.

Some studies have been carried out on the relationship between the two factors, however, there have never been any specific conclusions to date, for which 3 796 adults were invited from 2001 to 2011, a sufficient time interval, with certainty your results.

What was the study?

The research analyzed factors such as body weight, weight, height, waist circumference, and abdominal fat percentage.

This data was associated with estimation of vehicle noise exposure time.

Why should traffic noise be fat?

People who are more exposed to traffic noise actually have a higher risk of obesity. "We found that the increase of 10 decibels in the average noise exposure to the participants led to 17% higher obesity," says Maria Foraster, ISGlobal researcher, first author of the study.

The study looked at data from two aspects: a cross-cutting approach that allowed analysis of the participating population at the exact time of the study to investigate objective measures. On the other hand, a longitudinal perspective was examined to evaluate the development of obesity risk throughout the period.

In both cases, transport associations showed consistency, although there was a difference. In the case of overweight (but not obesity), it refers only to exposure to traffic noise in the cross-sectional analysis (at the exact times of the study).

This study increases the evidence of the possible impacts of traffic noise on obesity and identifies the same results as previous studies, but in the new population. "However, more work is needed to confirm the association and review some inconsistencies for which we have not yet been able to find consensual explanations," says Maria Foraster.
