The aim of this analytical cross‐sectional study was to evaluate the presence of work‐related musculoskeletal disorders (WMSD) among dental students in two Brazilian dental schools. The sample included 227 randomized subjects from fifth to ninth semesters who were developing clinical activities. Each student signed an informed consent form. A self‐reporting questionnaire was used to obtain data on the practice of physical exercise, the presence of pain during or soon after treating patients, and the adoption of preventive measures related to clinical activities. Results were analyzed using the Statistical Package for Social Sciences 13.0. The χ2 test was used to identify associations between variables. The presence of pain during or after clinical work was reported by 173 participants (76.2 percent). Statistically significant differences were found between gender and the occurrence of pain. Pain was present during clinical activities (p=0.006) and imposed limitations on the work routine (p=0.011). Among those who practiced physical exercise, eighty‐eight (74.6 percent) reported pain. The high percentage of pain reported by dental students suggests the value of reviewing work conditions in dental practices in order to minimize the exposure of all workers to WMSD.

In the last few years, the development of national and international games for the physically challenged has encouraged greater participation of athletes with physical disabilities. This resulted in an increase in intensity and frequency of the training routines and competitions and higher levels of trauma-orthopedic lesions. The aim of this descriptive-comparative study is to analyze statistically the incidence of trauma-orthopedic lesions of 82 physically challenged athletes selected in a non intentional and no probalistic way. These athletes belong to various sports categories, as follows: swimming = 37, table tennis = 19, athletics = 19, power lifting = 7. Sixty are males, 24, females, they range in age from 15 to 51 and they all took part in the 2002 World Championship. Applying the medical records of the Brazilian Paraolimpic Committee medical department filled in at those events (the technique of observing the athlete clinical-sports files and medical examinations), the result showed a recurrence of lesions in athletes in the following sports: athletics (MMII = 64.9%, backbone 19.3% and MMSS = 15.8%; power lifting (backbone = 54.5%, MMSS = 36.4% and MMII = 9.1%); swimming (MMSS = 44.4%, backbone = 38.9% and MMII = 16.7%) and table tennis (MMSS = 56%, Backbone = 36% and MMII = 8%). Such results lead to the conclusion that the performing of sports of the physically challenged athletes, and also the intensity of the training routing to try to beat their previous marks and results, cause these kinds of lesion. In addition, it is important to reinforce the preventive measures to the athletes.

The measures were compared between the two groups using the Student t-test for independent samples. Discriminant function analysis was applied to predict group allocation using the measures obtained as independent variables. The two groups differed significantly in terms of body weight, fat mass, height, maximum attack height, range of attack, and somatotype. Discriminant function analysis identified the somatotype measures (endomorphy, ectomorphy, and mesomorphy) with correlation coefficients below 0.30. The canonical correlation coefficient obtained with this function was 0.856. In conclusion, somatotype or vertical jump ability does not seem to distinguish elite athletes from non-elite athletes in under-17 female volleyball players, and height is the main morphological determinant to achieve elite level performance.

RESUMOIntrodução: O estudo do consumo alimentar fornece informações específicas sobre a ingestão de energia e nutrientes, podendo estar associado com o conhecimento sobre nutrição e alimentação. Nesse contexto, a entrada dos estudantes na universidade envolve uma tendência de transição nutricional e mudanças negativas no nível de atividade física, resultando em alterações importantes na sua composição corporal. Objetivo: Analisar a relação entre perfil antropométrico e o conhecimento nutricional de atletas universitários de futebol. Métodos: Participaram da pesquisa 37 universitários, jogadores de futebol, do sexo masculino, entre 18 e 28 anos, estudantes das áreas de Saúde e Biológica (SB), Tecnológica e Exatas (TE) e Humanas e Sociais (HS). Foram aferidas a massa corporal, estatura e dobras cutâneas (tricipital, subescapular, supra-ilíaca, abdominal e coxa medial). A fim de mensurar o conhecimento nutricional dos atletas, foi aplicado um questionário de conhecimento nutricional (QCN), traduzido, adaptado e validado para o Brasil. Para análise estatística foi utilizada correlação de Pearson e ANOVA one-way com post-hoc de Games-Howell. Resultados: Foi observada diferença na massa corporal, estatura e massa livre de gordura (MLG) entre os atletas. Na comparação entre as áreas, verificou-se que não houve diferença significativa entre os estudantes da área SB em relação aos demais. Também foi observado que não houve diferenças significativas para a parte I, parte II ou total de acertos. Ainda houve correlação positiva, forte e significativa da área HS com a MLG. Observando-se as demais variáveis na área TE, foi encontrada correlação negativa e moderada. No restante das variáveis, as correlações entre a pontuação obtida no QCN e as variáveis de composição corporal foram fracas. Conclusão: A amostra avaliada apresentou conhecimento nutricional moderado, verificando-se baixa associação deste com o perfil antropométrico. Os resultados também sugerem que o conhecimento nutricional, isoladamente, não é capaz de influenciar o comportamento alimentar.Palavras-chave: antropometria, avaliação nutricional, esportes, futebol.

It was found that school work performance indicators could be taken together with other indicators, such as development of various abilities, participation in other activities, activity motivation, behaviour and attitudes at home and at school, for evaluating social projects.
