Objective: To estimate the consumption of dairy products in the Brazilian population. Methods: Data from two non-consecutive food records from 34,003 individuals (aged ³10 years) in the first Brazilian nationally representative dietary survey (2008-2009) were used to estimate the dairy products intake. Dairy products were divided into four major subgroups: cow's milk, cheese, yogurt and other dairy products. Absolute and relative frequencies of individuals in the population who reported consumption of dairy products in at least one of the two-day food record according to sex, age, geographic region and levels of per capita monthly family income were calculated. Moreover, the mean consumption of dairy products, as well as their nutritional contribution in total energy, protein, calcium, phosphorus and magnesium intake was estimated. Results: It was observed that only 43.0% of the population reported consuming dairy products, being the milk subgroup the most frequently consumed (21.1%). The prevalence of consumption was higher among females, elderly, residents of the South region, and among individuals from higher per capita monthly family income. The nutritional contribution of dairy products was less than 10.0% of total energy intake and for most nutrients and the mean daily consumption are justified was 101.8g. Conclusion: Therefore, in view of the low intake of dairy products by Brazilian population and the nutritional benefits associated with this food group, public health strategies to increase dairy consumption are justified.

The aim of this population-based cross-sectional health survey (N = 532) was to investigate the factors associated with the probability and amounts of yogurt intake in Brazilian adults and the elderly. A structured questionnaire was used to obtain data on demographics, socioeconomic information, presence of morbidities and lifestyle and anthropometric characteristics. Food intake was evaluated using two nonconsecutive 24-hour dietary recalls and a Food Frequency Questionnaire. Approximately 60% of the subjects were classified as yogurt consumers. In the logistic regression model, yogurt intake was associated with smoking (odds ratio [OR], 1.98), female sex (OR, 2.12), and age 20 to 39 years (OR, 3.11). Per capita family income and being a nonsmoker were factors positively associated with the amount of yogurt consumption (coefficients, 0.61 and 3.73, respectively), whereas the level of education of the head of household was inversely associated (coefficient, 0.61). In this study, probability and amounts of yogurt intake are differently affected by demographic, socioeconomic, and lifestyle factors in adults and the elderly.

In this paper, we present and discuss stability diagrams for Paul traps driven by two ac voltages. In contrast to a typical Paul trap, here we suggest a secondary ac voltage whose frequency is twice the frequency of the primary one. The ratio between their amplitudes can be used to expand the region of stability and to access different states of motion of trapped ions. This provides a further mechanism to trap, cool, and manipulate single ions and also to improve the experimental framework where ion clouds and crystals can be prepared and controlled. Such approach opens the possibility of designing more sophisticated trapping architectures, leading to a wide variety of applications on ion trap research and mass analysis techniques.

Background: The importance of dairy products is recognized for their health benefits. However, additional investigation is required to understand the characteristics of the lifestyle of people who incorporate yogurt into their eating routine. Then, the aim of this study was to compare the lifestyle of yogurt consumers and non-consumers. Methods: A total of 2610 individuals between the ages of 18 and 59 years were recruited and selected for the study, having as the primary criterion the report of frequency of yogurt consumption. Two study groups were formed: consumers (frequency of yogurt consumption ≥ four times a week during the last year) and non-consumers (consumption frequency of less than once a week), paired for age, sex, and socioeconomic class. A structured questionnaire was applied to obtain the data regarding anthropometric characteristics (weight, height, and waist circumference), lifestyle (food consumption, physical activity, smoking, and alcohol consumption), socioeconomic information (relationship status, level of education, and work) and presence of morbidities. Based on the quantity of consumption in grams/day of yogurt and milk, cheeses, and fruit smoothies, four other analysis groups were formed: LOW-Y/LOW-D (low consumption of yogurt and other dairy products); LOW-Y/HIGH-D (low consumption of yogurt and high consumption of other dairy products); HIGH Y/LOW-D (high consumption of yogurt and low consumption of other dairy products); and HIGH-Y/HIGH-D (high consumption of yogurt and other dairy products). Chi-squared and Student's t tests were used to assess the relationships of these factors. Results: The yogurt consumers had a higher educational level (≥8 years: 83.8% vs. 79.9%), a higher frequency of individuals working and/or currently studying (67.7% vs. 65.5%), were more physically active at leisure time (17.2% vs. 14.3%), had reduced alcohol intake (3.6 g/day vs. 6.4 g/day) and a lower frequency of smoking (21.7% vs.

Avaliar o consumo de alimentos não recomendados em crianças assistidas no âmbito da Atenção Primária à Saúde no município de Porto Alegre, RS. Materiais e Métodos: A amostra compreendeu crianças residentes no território de cobertura de vinte Unidades de Saúde. As mães das crianças de 6 a 9 meses de idade responderam a um questionário fechado, em que ela confirmava ou não se a criança já tinha consumido determinados alimentos. Posteriormente, na idade de 12 a 15 meses, foi realizada nova investigação quanto ao consumo dos mesmos alimentos no último mês. Resultados: Refrigerante, bala ou pirulito e biscoito recheado foram consumidos por, aproximadamente, 40% das crianças na idade de 6 a 9 meses e 80% na idade de 12 a 15 meses. A prevalência de consumo de açúcar de adição, queijo petit suisse e gelatina foi superior a 70% nos dois momentos. Alimentos fritos e chocolate foram consumidos por mais de 80% na idade de 12 a 15 meses. Conclusão: Os resultados mostram elevada prevalência de consumo de alimentos não recomendados para crianças menores de dois anos, enfatizando a necessidade de sensibilização, formação e preparo dos profissionais da Atenção Primária à Saúde para a realização de aconselhamento dietético. Palavras-chave: lactente; consumo de alimentos; atenção primária à saúde.
