Objective: To investigate the correlation between the consumption of refined carbohydrates and fats and the prevalence of obesity in the state capitals of Brazil. Design: An ecological evaluation of obesity and dietary risk factors was carried out in twenty-six state capitals of Brazil. Setting: Analysis was based on the age-standardized prevalence of obesity (BMI $ 30?0 kg/m 2 ) among adults aged 20-59 years. Both intake and obesity prevalence were obtained from the last National Family

In each household, during seven consecutive days, all monetary and non-monetary expenses for food and beverages for family consumption were transformed into energy. The relative contribution of foods and food groups was expressed as the proportion (%) of total energy. Fruits and vegetables were also measured by the quantity bought in grams. Results: Prevalence of obesity varied from 5?1 % to 13?6 % among women and from 5?2 % to 17?6 % among men. For women, there were statistically significant correlations between obesity and intake of sugar and soft drinks (r S 5 0?60; P 5 0?001), ready-to-eat meals (r S 5 0?39; P 5 0?05) and potatoes (r S 5 0?40; P 5 0?04). For men there were no such associations. Conclusions: Increasing intake of refined carbohydrates, mainly soft drinks, may play a role in the prevalence of obesity among women in Brazil. Effecting changes in family purchase patterns may be a strategy to reduce obesity.
