, a new U.S. study shows that the number of fast food restaurants on commuter roads is significantly associated with a large body mass index (BMI), or body mass gain.
researchers analyzed data from 710 elementary school employees in New Orleans, Louisiana. Based on the existing database, the researchers determined the number of supermarkets, grocery stores, restaurants and fast food outlets within 1 km of the employee's residence, office and the shortest commute between the two places. The results showed that the more fast food restaurants near commuter routes, the greater the body mass index of the study subjects, and the greater the number of supermarkets, grocery stores and fast food restaurants near the residence, but the number of restaurants near the office was not associated with the body mass index.
body mass index (BMI) is a common measure of weight and thinness, calculated by divided by the square of height (meters). According to current standards, body mass index between 25 and 30 is overweight and more than 30 is obese.
the study, published in the latest issue of the journal Public Library of Science, said the study shows that we "need to pay attention to multiple environmental factors that affect body mass index." The number of fast food restaurants near commute routes gives people "endless access to fast, cheap and unhealthy food, which in turn leads to a higher body mass index". The researchers will analyze the specific commute routes and food buying habits of the subjects, combined with other measures of physical fitness, to find health-promoting interventions.
