Abstract

Introduction The proportion of food purchased for out-of-home eating in Brazil has been increasing.

Objective To evaluate dietary habits associated with out-of-home eating among Brazilian adults.

Methods We analysed data of 135 249 adults (20–65 y), living in 27 Brazilian cities, from the 2007, 2008 and 2009 Telephone Survey System for the Surveillance of Risk and Protective Factors for Chronic Non-Communicable Diseases (VIGITEL). Frequency of out-of-home eating was based on the reported frequency of consuming lunch and dinner away from home per week. Dietary habits were based on the reported consumption of visible fat in meat and chicken and the daily consumption of soft drink, fruit and milk. Frequencies were weighted and analysis incorporated the complex design of the survey.

Results Men reported eating out more frequently than women (52.2% vs 39.4% for at least once per week). Consumption of visible fat and soft drink increased with the frequency of out-of-home eating (p<0.008), whereas daily fruit and milk consumption decreased (p<0.01). After controlling for age and years of schooling, the OR of consuming fruit and milk decreased with the frequency of out-of-home eating (OR=0.76 (95% CI 0.68 to 0.86), OR=0.79 (95% CI 0.70 to 0.90) among men and OR=0.69 (95% CI 0.62 to 0.76), OR=0.76 (95% CI 0.69 to 0.84) among women, respectively, comparing 5 or more times/week with no out-of-home eating).

Conclusion Frequency of out-of-home eating was positively associated to negative markers of dietary habits and negatively associated to healthy markers of dietary habits among Brazilian adults. Due to the increasing out-of-home eating, public health strategies should be developed.
