Abstract
There is growing concern with the increasing prevalence of obesity in industrialised
countries, a trend that is more apparent in the poor than in the rich. In an ecological
study, the relationship between an area measure of socioeconomic status (SES) and
the density of fast-food outlets was examined as one possible explanation for the
phenomenon. It was found that there was a dose-response between SES and the density
of fast-food outlets, with people living in areas from the poorest SES category having
2.5 times the exposure to outlets than people in the wealthiest category. The findings
are discussed.
