Breakfast eating among Brazilian adolescents: Analysis of the National Dietary Survey 2008-2009

Objetivo: Caracterizar o desjejum dos adolescentes brasileiros. Metodos: O consumo alimentar foi estimado com base em um dia de registro alimentar de adolescentes entre 10 e 19 anos de idade do primeiro Inquerito Nacional de Alimentacao (2008-2009). Considerou-se como desjejum a primeira ocasiao de consumo alimentar entre 4 e 11 horas da manha. Resultados: Noventa e tres porcento dos adolescentes realizaram desjejum. Essa refeicao contribuiu com 17,7% da ingestao diaria de energia. Os grupos de alimentos mais consumidos foram: cafe e cha, paes, manteiga/margarina, leite, bolos e biscoitos, salgadinhos e chips, preparacoes a base de milho, queijo, carnes processadas e suco da fruta. Na regiao Norte observou-se frequencia mais elevada de consumo de cafe e cha e de raizes e tuberculos e menor relato para leite do que nas demais regioes. Na regiao Nordeste, destaca-se o consumo de milho e de ovos e na regiao Sul, o de carnes processadas e frutas. Adolescentes de familias do primeiro quartil de renda relataram frequencia mais elevada de consumo de cafe e cha, salgadinhos e chips, milho e raizes e tuberculos e menor relato para o grupo do leite. Os adolescentes de familias do quartil mais elevado de renda referiram consumo mais expressivo de leite, suco de fruta, queijo e bebidas com adicao de acucar. Conclusao: No Brasil, o desjejum dos adolescentes tem baixa contribuicao para o consumo diario de energia. A qualidade nutricional do desjejum melhora com o incremento da renda. Os tres principais itens consumidos foram cafe/cha, paes e manteiga/margarina.

Changes in beverage consumption among adolescents from public schools in the first decade of the century XXI

OBJECTIVE To evaluate the changes in beverage consumption among adolescents between 2003 and 2008. METHODS Two school-based cross-sectional studies were carried out with public school students (12 to 19 years-old) from Niterói, Rio de Janeiro, Brazil. Data from three food records were used to estimate daily, weekdays and weekend average consumption (volume and percent contribution for total daily energy intake) of milk and milk-based beverages, sugar sweetened beverages, fresh squeezed fruit juices, caffeinated and alcoholic beverages. Beverage consumption age-adjusted means for weekdays and weekends were compared using linear regression (Generalized Linear Models - GLM). RESULTS A total of 433 adolescents were examined in 2003, and 510 in 2008. The prevalence of overweight was 17% in 2003 and 22% in 2008 (p > 0.05). Milk was the most consumed beverage, being reported by 89% of adolescents, followed by sodas (75%). In general, in the five-year period, there was an increase in the prevalence of consumption of alcoholic drinks, guarana syrup refreshment, and processed fruit drinks, especially on weekdays. The soft drink was the largest contributor to the total energy consumption, corresponding on average to 4% of daily energy intake. CONCLUSION The main changes in the beverage consumption among adolescents from Niterói, in the first decade of the XXI century, were the tendency to reduce the consumption of milk and the increase in the consumption of processed and alcoholic beverages.

Objective To describe meal consumption habits and assess their associations with anthropometric indicators.

Consumo alimentar segundo os dias da semana – Inquérito Nacional de Alimentação, 2008-2009

ABSTRACT 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. The mean (and standard deviations) and frequencies (%) of energy, nutrients, and food groups consumption were estimated for weekdays (Monday to Friday) and weekend (Saturday and Sunday), we then estimated the differences according to the days of the week for the population strata analyzed. RESULTS The average daily energy intake for the weekend was 8% higher than the one observed for weekdays. The average percentage contribution of carbohydrate to the daily energy intake was higher during the week compared to Saturday and Sunday (56.3% versus 54.1%, p < 0.01). The inverse was observed for averages of the contribution to the daily intake of energy from total fat (26.8% versus 28.4%), saturated fat (9.1% versus 9.9%) and trans fat (1.4% versus 1.6%). The most significant changes between weekdays and weekend days were observed for eggs, sugar-added beverages, puff snacks and chips, beans, and pasta. During weekends, the frequency of beverage with added sugar consumption increased by 34%, the amount consumed increased by 42%, and the contribution to energy intake increased by 62% when compared to weekdays. CONCLUSIONS The Brazilian population increases energy intake and unhealthy food markers on weekends compared to weekdays.OBJETIVO Avaliar as variacoes na ingestao de energia, nutrientes e grupos de alimentos entre dias da semana e dias de fim de semana na populacao brasileira.
