Abstract The prevalence of overweight and obesity is increasing rapidly worldwide and it is assumed that the masticatory function might influence the nutritional status of these individuals; moreover, this condition can also negatively affect their quality of life due to the impact in physical, psychological and social aspects. Therefore, the aim of this study is to assess the relationship between masticatory function, nutritional evaluation, symptoms of anxiety and the quality of life of 300 pre pubertal children of both genders, aged 6-10 years. The masticatory function will be verified by evaluating the maximum bite force and characteristics of food consistency. Presence and history of sucking and parafunctional habits will also be surveyed. These variables of the masticatory function will be related to anthropometric measurements (body mass index, triceps and subscapular skinfolds, arm and waist circumferences) and food intake, measured by 24-hour recall and the calculation of estimated food intake by means of software. Furthermore, symptoms of anxiety and quality of life scores of the subjects will be evaluated using translated and validated questionnaires (Multidimensional Anxiety Scale for Children-MASC and Autoquestionnaire Qualité de Vie Enfant Imagé-AUQEI, respectively). The results will be analyzed by descriptive statistics, Komolgorov-Smirnov normality test, correlation tests (Pearson or Spearman) and analysis of variance (ANOVA) between groups. There will also be assessed the psychometric properties of scales: internal consistency (ceiling and floor effects, Cronbach Alpha coefficient, weather correlation matrix, and corrected item-total correlation) and discriminant validity (t-test). Multiple linear regression models will be used to verify the relationship between anthropometric measurements (as dependent variables) and the scores for quality of life and anxiety, masticatory function variables and dietary intake, adjusting for gender, age, orthodontic treatment need and DMFT and dmft indices (alpha = 0.05). | |
