Estimates of obesity trends in Brazil, 2006-2009

This study investigates the prevalence and trends of obesity among Brazilian adults, from 2006 to 2009, according to socio-demographic variables.

Data from the Surveillance System of Risk and Protective Factors for Chronic Non-Communicable Diseases through Telephone Interviews (VIGITEL) from a sample of adults living in all state capitals were used. Approximately, 41,500 individuals were interviewed each year. Obesity prevalence and recent trends were estimated in the total population and according to socio-demographic variables.

In 2006, the obesity level reached 10.8% of adults, increasing to 13.5% in 2009. The increase in obesity was higher among women than men. For women, low levels of education and unemployment are also important factors. For men, higher obesity rate is seen among those who are young, resident of southeast region, higher educated and employed individuals.

Despite obesity rates in Brazil not being among the highest in the world, the rapid increase in these rates, greater in women than men, demand immediate care. These findings will help to formulate strategies needed to reduce and prevent obesity.
