A choice architecture intervention targeting school meals and water frequency intake: A school-based randomized trial.

Our aim was to evaluate the impact of choice architecture on school meals and water intake frequency. We conducted a school-based randomized trial in seven elementary municipal public schools (control = 3; intervention = 4) in Rio de Janeiro, Brazil. The interventions group received the following modifications: (1) banner of the daily school meal menu and two superheroes, (2) waterproof tablecloths, (3) posters on healthy eating habits, (4) displays with playful names, (5) new containers for fruits, and (6) colored footprints for one month.

Do they really support "your freedom of choice"? FoPNL and the food industry in Brazil.

Introduction: In 2020, Brazil approved the introduction of a new front-of-package nutrition labeling (FoPNL) in the format of a magnifying glass (MG) after years of discussion. There is currently a lack of understanding of the role of the food industry in that process. This study aimed to describe the corporate political activity (CPA) of the food industry and conflicts of interest situations, as they happened during the development and approval of a new FoPNL system in Brazil.

Regulatory measures for the protection of adequate and healthy diet in Brazil: a 20-year analysis.

Regulatory measures are among the strategies for the promotion of adequate and healthy diet recommended by the Brazilian National Food and Nutrition Policy (PNAN). Although other actions in the promotion of adequate and healthy diet have made strides in Brazil, regulatory measures have made slow progress. The study aimed to identify and describe factors related to the development and implementation of the principal regulatory measures for the protection of adequate and healthy diet in Brazil in the last 20 years.

Breakfast patterns and weight status among adolescents: a study on the Brazilian National Dietary Survey 2008-2009.

Examining the composition of breakfast concerning weight status is essential for evaluating adolescent health and understanding this gap. This study aimed to identify breakfast patterns and investigate the relationship with weight status among Brazilian adolescents. We used a subsample of 7425 adolescents aged 10-19 years from the 2008-2009 Brazilian Household Budget Survey.

School-based obesity interventions in the metropolitan area of Rio De Janeiro, Brazil: pooled analysis from five randomised studies.

School-based studies, despite the large number of studies conducted, have reported inconclusive results on obesity prevention. The sample size is a major constraint in such studies by requiring large samples. This pooled analysis overcomes this problem by analysing 5926 students (mean age 11·5 years) from five randomised school-based interventions.

Breakfast Consumption, Family Breakfast, and Adiposity Trajectory in Adolescence-The Adolescent Nutritional Assessment Longitudinal Cohort Study.

Background: The relationship between breakfast and family breakfast and adiposity gain during adolescence remains inconclusive.

Objective: This study aimed to investigate the relationship between breakfast and family breakfast frequency and adiposity trajectory in adolescence.

Design: Prospective cohort study with middle school students aged 10 to 16 years enrolled in 2010 (baseline) and followed for 3 years.

Changes in breakfast frequency and composition during adolescence: The Adolescent Nutritional Assessment Longitudinal Study, a cohort from Brazil.

Objectives: To estimate changes over time of breakfast frequency and foods/food groups consumed at breakfast.

Methods: Cohort of 809 students aged 10-16 years old from Rio de Janeiro, Brazil, enrolled in 2010, and followed for three years. Breakfast skippers were those not eating breakfast.

Food Consumption According to the Days of the Week - National Food Survey, 2008-2009.

Objective: Evaluate the variations in energy, nutrients, and food groups intake between days of the week and weekend days in the Brazilian population.

Methods: We used data from the first National Food Survey (2008-2009) of a one-day food log of a representative sample of the Brazilian population aged 10 years or older (n = 34,003). For the analyses, we considered the sample weights and the effect of the study design.

Perception of food consumed at home and dietary intake: A nationwide study from Brazil.

Perception of food consumed is a key factor in acknowledging the need for behavioral change to improve diet quality. We analyzed family dietary intake according to the head of household's perception of satisfaction with food consumed by the family. Households (n = 13,351) that participated in the Brazilian Household Budget Survey and the National Dietary Survey were classified as satisfied or dissatisfied with the food consumed in the home.

Maternal mental health and nutritional status of six-month-old infants.

Methods: A cross-sectional study with 228 six-month-old infants who used primary health care units of the city of Rio de Janeiro, Southeastern Brazil. Mean weight-for-length and mean weight-for-age were expressed in z-scores considering the 2006 World Health Organization reference curves.
