Availability of fast food restaurants on the route between children's houses and their schools does not affect children's weight especially when gender, age, race, ethnicity and location were included.

‘Rising concern regarding childhood obesity is the top in the United States. Availability of fast food restaurants on the route between children's houses and their schools does not affect children's weight especially when gender, age, race, ethnicity and location were included.’

Rising concerns are emerging by many public health figures about the role of fast-food restaurants on food consumption and resulting obesity in children. Local governments in the United States may influence children's food options through the zoning process. With this regards, several fast-food restaurants near schools are considered to be banned in cities, including Austin, Texas, and New York. 




Childhood Obesity and Availability of Fast - Food Restaurants
The study team investigated the effect of fast-food restaurants availability on childhood weight outcomes by gender, age, race, ethnicity and location using Arkansas student Body Mass Index. Data collected from 2004 to 2010 were matched to home and school address through annual school registration records.
Using a radius of one-half mile to define exposure near home and school, the mean total exposure level is 3.34 restaurants. The majority of children in the sample had zero exposure within 0.5 miles of home (69.6%). In contrast, 45.2% of children have at least one fast-food restaurant located within 0.5 miles of their school.
Changes in fast-food exposure as students changed schools – from elementary school to junior high school over time were also taken into account. It was observed that changes in exposure have no effect on BMI z- score.
