- Eating out of home in Portugal: characterization and effects on dietary intakePublication . Silva, Mariana; Rodrigues, Sara S.P.; Correia, Daniela; Rei, Mariana; Severo, Milton; Costa, Ana Isabel A.; Torres, Duarte; Lopes, CarlaThis cross-sectional study aims to describe and compare energy, nutrient intake, and food consumption according to eating location and by age groups using data from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015/2016). Dietary intake was estimated by two non-consecutive days of food diaries (children)/24-hour recalls (other age groups) and four eating location categories were defined according to the proportion of meals consumed at out of home locations: Home (at least 80% of meals at home), Other Homes, School or Work and Restaurants and Other Places. The majority of meals (69.1%) were consumed at home. Meals were also often taken at school by children and adolescents, and in restaurants and similar outlets by adults and elderly. Children and adolescents in the School or Work category ate more fruit, vegetables and pulses and cereals and starchy tubers, whereas adults in this category ate more red and processed meats, sugar sweetened beverages and sweets. Compared to Home category, Restaurants and Other Places was associated with worse diet adequacies among children (β=-1.0; 95%CI=-2.0,-0.04), adolescents: (β=-2.4; 95%CI=-3.2,-1.5) and adults (β=-1.3; 95%CI=-1.6,-1.0) reflecting higher intakes of energy, fat, trans and saturated fatty acids, and sodium. The elderly consumed more free sugars and fat when eating out of home in general. Overall, findings reflect important variation in nutrient profiles by eating location, with meals taken at school or work contributing to higher consumption of nutrient-dense foods and those taken in restaurants and other similar settings implying higher consumption of energy-dense foods.
- Factors influencing food waste during lunch of fourth-grade school childrenPublication . Martins, Margarida Liz; Rodrigues, Sara S.P.; Cunha, Luís M.; Rocha, AdaThis study aims to explore the factors that influence plate waste at lunches served in primary schools. Data was collected for all fourth-grade children attending 21 primary schools from the city of Porto (Portugal) (n = 463). Plate waste was evaluated by the weighing method and factors influencing plate waste were collected by observation of menu and canteen characteristics and through the application of a questionnaire to children aiming to evaluate factors related to preferences and dietary patterns. Logistic regression was performed to identify predictors of plate waste. It was observed that fish menus and composed dishes showed a higher tendency for increased plate waste. However, this effect was not observed when adjusted for other variables. Soups without pulses and blended soups were less likely to be discarded by children. The presence of the teacher during meals and the possibility for children to leave the canteen whenever they wish, protected both the main dish and the soup from being wasted. A higher number of children in the canteen was associated with increased soup waste. As expected, children more pleased with the sensory characteristics of the main dish and soup were less likely to waste food. Children who consumed high-saturated fat content mid-morning snacks were more likely to waste soup. The main factors associated with plate waste were related to the presence of teachers during the mealtime, school meal policies and the meals’ sensory characteristics. Additionally, soup waste was determined by its composition, mid-morning snacks and the number of children in the canteen.
