This thesis is composed by four articles that focused on the impact of food consumed away from home on the diet and body weight of the Brazilian population. The first article is a systematic review of the scientific evidence of the association between food away from home and body weight with a quality assessment of published articles in scientific literature. We evaluated 28 articles and results suggested a positive association between the consumption of food away from home and weight gain. The review showed that one of the limitations in this area is the lack of standard definition and methods to assess away-from-home eating. For the other articles, data from the Brazilian National Dietary Survey (NDS) conducted along with the Household Budget Survey (HBS) 2008-2009 were used to characterize the consumption of food away from home (article 2); to investigate the association between away-from-home food consumption and total energy intake (article 3), and body weight (article 4). Analyses were conducted with 34,003 individuals over 10 years old with data on food intake collected through food records in two non-consecutive days. The records included detailed description of the food and the amount consumed, type of preparation, and time and place of consumption (at home or away from home). Away-from-home food was defined as all foods purchased and consumed outside the home. The first day of record was used in the analyses, taking into account the sample weight of NDS and the sample design. The consumption of food away from home in Brazil was reported by 40% of the respondents; decreased with age and increased with income in all Brazilian regions; it was higher among men and in urban areas. The groups with the highest percentage of food consumption outside the home were alcoholic beverages, baked and deep-fried snacks, pizza, soft drinks and sandwiches. Among those living in urban areas (n=25,753), the mean energy intake from away-from-home food was 337 kcal, accounting for 18% of total energy intake. Food away from home was positively associated with total energy intake. Evaluating only adults between 25 and 65 years old in urban areas (n=13,736), we found no association between the consumption of food away from home and Body Mass Index (BMI). Individuals who consumed food away from home had a lower intake of protein, higher intake of total fat, saturated fat, and free sugar, low consumption of rice, beans and milk and higher consumption of baked and deep-fried snacks, sweets and sugar, soft drinks, and alcoholic beverages than non-consumers. Despite the lack of association between eating out and being overweight, the consumption of food away from home influences diet quality and in long-term it can have an impact on weight gain of the population. Therefore, it should be considered in public health strategies aiming at improving the diet of Brazilian population.
