Government regulation of fast food chains could halt the global rise in obesity, a paper published in the Bulletin of the World Health Organization has concluded. The paper looked at the number of fast food transactions per capita in 25 high income countries from 1999 to 2008 and compared this with changes in the average body mass index (BMI) of the population. During that period the average number of fast food transactions per capita each year increased from 26.61 to 32.76, and BMI increased from 25.8 to 26.4. The largest increases in fast food transactions occurred in Canada, Australia, Ireland, and New Zealand, while the lowest occurred in Italy, Greece, the Netherlands, and Belgium. Researchers compared these results with market deregulation by using the Index of Economic Freedom, which was developed by the Wall Street Journal and the Heritage Foundation, a US think tank. The index marks countries each year on a scale of 1 to 100, where a low score (<50) means that a country is not economically free. Researchers found that each unit increase in the economic index was associated with an increase of 0.27 in the average number of per capita fast food transactions each year. And each singleunit increase in fast food consumption was associated with an increase of 0.02 in people’s BMI.
