RESUMOObjetivo: O objetivo do estudo foi avaliar a checagem corporal, a atitude alimentar inadequada e a insatisfação corporal em universitários de ambos os sexos. Métodos: Participaram 587 indivíduos (311 homens). Foram avaliados os comportamentos de checagem (mulheres -Body Checking Questionnaire; homens -Male Body Checking Questionnaire), as atitudes alimentares inadequadas (Eating Attitudes Test-26) e a insatisfação corporal (Body Shape Questionnaire). Massa corporal e estatura foram autorreferidas para o cálculo do índice de massa corporal (IMC). Foi realizada estatística descritiva, inferencial e teste qui-quadrado (teste exato de Fisher) utilizando o software Statistic 8.0 e adotado nível de significância de 5%. Resultados: A checagem corporal está associada às atitudes alimentares inadequadas e à insatisfação corporal, independentemente do sexo do indivíduo. Foram encontradas diferenças entre o sexo feminino e masculino para as variáveis avaliadas, sendo maior a frequência entre as mulheres. Conclusão: Concluiu-se que a checagem corporal é um comportamento presente e de alta frequência em universitários com risco para o transtorno alimentar e também naqueles insatisfeitos com sua imagem corporal. ABSTRACTObjective: The aim of this study was to evaluate the body-checking, inappropriate eating attitudes and body dissatisfaction in undergraduate students from both sexes. Methods: Five hundred eighty-seven undergraduate students (311 men) were surveyed. The body-checking behaviours (women -Body Checking Questionnaire; men -Male Body Checking Questionnaire), inappropriate eating attitudes (Eating Attitudes Test-26) and body dissatisfaction (Body Shape Questionnaire) were evaluated. Body mass and height were self-referred to calculate the body mass index (BMI). Descriptive, inferential and qui-square test (Fisher exact test) statistics were performed using the Statistic 8.0 software and adopting significant level of 5%. Results: Body-checking behaviours are associated with inappropriate eating attitudes and body dissatisfaction in both sexes. Women and men showed differences between the varia-

The body image of pregnant women is an issue that should be further investigated by pro-

Objective: To analyze body image in different periods of adolescence. Methods: This cross-sectional study enrolled students aged ten to 19 years old of public schools in small districts of Minas Gerais, Southeast Brazil. The Body Shape Questionnaire (BSQ), the Body Dissatisfaction Assessment Scale for Teenagers and the Silhouette Scale for Teenagers (SST) were used. Adolescence phases were classified according to the subjects' ages. Weight and height were measured in order to calculate the body mass index and the nutritional status. Results were analyzed by logistic regression. Results: The study emolled 531 teenagers (318 females). The average age was 15.6±2.2 years and 84.6% were eutrophic. The prevalence of body dissatisfaction varied from 28.9% (BSQ) to 78.9% (SST). Overweight adolescents presented greater dissatisfaction (BSQ: OR 3.66, p<0.001; SST: OR 4.108, p<0.001). Dissatisfaction also occurred for females and those at the early adolescence (p<0.05). Conclusions:A low prevalence of dissatisfaction with the body image was observed among adolescents in small towns of Minas Gerais; however, most of them wished a different silhouette than the current one. The results showed that younger adolescents had higher dissatisfaction than their peers, as well as female and overweighed adolescents.

The safety and availability of sociotechnical critical systems still relies on human operators, both through human reliability and human ability to handle adequately unexpected events. In this article, the authors focus on ergonomic field studies of nuclear power plant control room operator activities, and more specifically on the analysis of communications within control room crews. They show how operators use vague and porous verbal exchanges to produce continuous, redundant, and diverse interactions to successfully construct and maintain individual and mutual awareness, which is paramount to achieve system stability and safety. Such continuous interactions enable the operators to prevent, detect, and reverse system errors or flaws by anticipation or regulation. This study helps in providing cues for the design of more workable systems for human cooperation in nuclear power plant operation.
