The objective of this study was to estimate the reliability of the alcohol use disorders identification test (AUDIT) applied to adolescents. Evaluations were performed with 141 students of ages ranging from 14 to 17 years (14.93±0.62). The internal consistency of the instrument was estimated by Cronbach’s alpha coefficient and its reproducibility by weighted Kappa statistics by score and by a reliability interval of 95%. The AUDIT presented excellent internal consistency (α=0.80, rinter-item=0.29). Most questions present reproducibility ranked as “good”. It is concluded that the AUDIT is a reliable instrument to survey information about alcohol use in adolescents.

Over the last decades of the 20th century, our society started an endless search for an ideal of beauty, advertised intensely by mass communication media. The concept of beauty pursued is being young, beautiful and thin. Thus, teenagers eventually die in the search for an ideal of body dominated by fat-fearing ideas. This article is a report about the field experience, during the collection of data for elaborating our Master’s Degree Dissertation on anorexia and adolescence. We went through an internship in an Eating Disease Program of a Mental Health Ambulatory from a Public University in the State of Sao Paulo, where we were able to experience the service organization, attention to users and the experience of anorexia, by the users in treatment. As the main result from this experience, it is possible to indicate the clientele profile, comprised predominantly by teenage girls, obsessed with the incessant pursuit of being thinner.

The objective was to evaluate levels of multiple supplements supplied to beef heifers in low supply of pasture on intake and nutrients digestibility, pH and concentration of ruminal ammonia nitrogen, nitrogen balance, synthesis and microbial efficiency. Five Nellore heifers with initial body weight of 344.00 +/- 21.10 kg and average initial age of 22 months were used. The following supplements were evaluated as fed to the animals: control (mineral supplement) and supplementation levels of 2, 4, 6 and 8 kg/animal/day, composing the following percentages of body weight (BW): 0.55, 1.11, 1.66 and 2.22%, respectively. The experimental design was a Latin square with five replications and five supplements. Intakes of total dry matter, crude protein (CP) and total digestible nutrients, and total apparent digestibility of dry matter, crude protein, total carbohydrates and no fiber carbohydrates increased linearly (P <0.0001) and dry matter intake of forage decreased (P <0.0001) with supplementation levels. Supplementation strategies promoted reduction on ruminal pH (P = 0.0343) and increased concentration of ruminal ammonia nitrogen (NH3-N) (P = 0.0004) before the supply of supplements, and after, this NH3-N presented quadratic behavior (P = 0.0023). Nitrogen intake, excretion of urea in urine and nitrogen excretion in feces increased linearly (P <0.0001) according to supplementation levels. The supply of high levels of multiple supplements reduces forage intake and presents itself as an alternative to cattle maintained in a systems with low supply of pasture in the dry season.

Para avaliar e planejar dietas para indivíduos e grupos populacionais são necessárias estimativas muito acuradas das necessidades e do consumo de energia. O objetivo foi realizar uma revisão bibliográfica das metodologias de determinação das necessidades energéticas para adultos e dos métodos de avaliação do consumo. Em 1918, Harris e Benedict propuseram equações que estimam a necessidade energética basal a partir de calorimetria indireta para indivíduos, depois disso, foram propostas outras equações para o cálculo das necessidades de energia em repouso ou em atividade. Recentemente, a água duplamente marcada é empregada para propor equações mais apropriadas. Contudo, a acurácia destas equações pode ser questionada. Por outro lado, os métodos de avaliação do consumo energético apresentam limitações que demandam cuidado na escolha e aplicação, assim como na interpretação dos resultados. A escolha do método de avaliação depende e pode ser influenciada pela população avaliada, tipo e objetivo do estudo, tempo disponível e do treinamento dos avaliadores. Deste modo, a avaliação do balanço energético está condicionada, tanto às limitações da avaliação através de equações, quanto dos métodos existentes de avaliação do consumo alimentar.

The objective was to map the prevalence of nutritional disorders in children attending the 1st to 4th grade of 12 public elementary schools located in the 5 administrative regions of Piracicaba, SP, each with its own socioeconomic profi le, from 2003 to 2006. A total of 16,068 children, divided into 8,133 (50.6%) girls and 7,935 (49.4%) boys, aged 7 to 11 years, were weighed and measured. Their nutritional status indicators heightfor-age (H/A), weight-for-age (W/A), and body mass index-for-age (BMI/A) were compared with those of the NCHS/CDC 2000 reference population and classifi ed according to the z-score cut-off points recommended by the World Health Organization. During that period, the Western Region, which has the lowest socioeconomic indicators, had the lowest z-score medians of the three anthropometric indicators assessed (p<0.0001) and was the only region to have a higher-than-expected stunting prevalence (3.0% with Z < -2). Excess weight prevalence was higher than expected in all regions. The Central Region, which has the highest socioeconomic indicators, had the highest excess weight prevalence (6.0% with Z > 2). Time had a positive effect on the stunted children, reducing the stunting rates in the regions with the lowest socioeconomic indicators. In conclusion, the three nutritional status indicators showed results suitable to the social and economic characteristics of each region. Although nutritional disorders have particular characteristics, they are a problem to the entire population.

Quando falamos de exercício resistido e suplementação nutricional, temos como objetivo principal o encurtamento do tempo entre a situação atual e o resultado esperado, e também a melhora do rendimento durante o treinamento, entretanto, para que não ocorra excessos nem desvios do objetivo real, o consumo deve ser feito de forma correta, embasado em estudos científicos.
