ABSTRACT Objective: To evaluate the prevalence of temporomandibular dysfunction (TMD) and its association with perceived stress and common mental disorder (CMD) in academic students. Methods: This is s transversal observational study conducted at Universidade de Minas Gerais, Divinópolis Unit, in health science courses. To investigate the prevalence of TMD, the anamnestic index by Fonseca was used. Stress was assessed by the perceived stress scale, translated and adapted for the Brazilian population in 2006. To track CMD, we used the Self-Reporting Questionnaire (SRQ-20). Data were analyzed using SPSS version 13.0, adopting a 5% significance level. Results: The prevalence of TMD in the sample was 71.9%, distributed as follows: Light TMD (50.0%), moderate (16.4%) and severe (5.5%), being more frequent among women (76.4%). Common mental disorders were present in 29.9% of participants. The average perceived stress was 30.9. Conclusion: The results of this study allow us to conclude that there is a statistically significant correlation between TMD and variables such as parafunctional habits, perceived stress and CMD. Level of Evidence II, Development of diagnostic criteria on consecutive patients (with universally applied reference "gold" standard).

A prevalência da obesidade tem crescido de forma significativa nos últimos anos transformando-se em um grave problema de Saúde Pública. O presente trabalho teve por objetivo avaliar a prevalência do excesso de peso em um grupo de crianças de seis a dez anos da rede pública de ensino da cidade de Formiga - MG, e comparar o desempenho físico das crianças com sobrepeso e obesidade, com o das crianças eutróficas. A pesquisa envolveu 357 estudantes, em três escolas da rede pública de ensino da cidade. Foram avaliadas a flexibilidade, a força explosiva, a velocidade, o peso corporal e a altura. De acordo com os dados obtidos 76,19% dos alunos foram classificados como eutróficos, 11,48% como obesos, 6,44% como sobrepeso, 2,8% como desnutridos e 3,08% em risco de desnutrição. Os resultados dos testes de flexibilidade, força explosiva e velocidade mostraram que as crianças com sobrepeso e obesidade apresentaram desempenho inferior em relação às crianças eutróficas.

The prevalence of obesity has significantly grown in the recent years, becoming a serious Public Health issue. The aim of the present study was to analyze the prevalence of overweight and obesity in children aged six to ten years in public schools in the municipality of Formiga, Minas Gerais State, Brazil, checking whether excessive weight interferes with physical performance, comparing obese children to eutrophic ones. The research was developed in three public schools, with a sample of 357 students. Tests were performed to evaluate flexibility, explosive strength, speed, corporal weight and height. The study classified 76.19% children as eutrophic, 11.48% as obese, 6.44% as overweight, 2.8% as underweight and 3.08% at risk of being underweight. The results of flexibility, explosive strength and speed tests indicated that overweight and obese children have poorer performance when compared with eutrophic ones.
