Quality of life evaluation and the nutritional, salivary and masticatory characteristics of pre pubertal overweight and obese children


The prevalence of overweight and obesity is increasing rapidly worldwide and it is assumed that chewing may have a bearing on the nutritional status of these individuals; moreover, this condition can also adversely affect their quality of life due to the physical, psychological and social impacts. Therefore, the aim of this study is to assess the relationship between masticatory function and nutritional, anxiety symptoms and quality of life of 300 prepubertal children of both genders aged 6 to 10 years. The masticatory function will be checked by evaluating the maximum bite force, food consistency, analysis of saliva and masticatory performance (MP). MP will be determined by the individual ability of fragmentation of a chewable test material called Optocal plus and sieving technique. Salivary flow rate will be determined by collecting saliva with mechanical stimulation (chewing Parafilm ®) and without stimulation, and then analyzed for pH and concentrations of total protein, amylase, calcium, urea, phosphate and triglycerides by means of spectrophotometry. Furthermore, the thresholds of the four primary tastes be evaluated (sweet, salty, sour and bitter) in three different concentrations. 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 circumference and waist circumference) and dietary intake, measured by 24-hour recall and calculation of estimated dietary intake by means of software. Furthermore, anxiety symptoms and quality of life of these individuals will be assessed using translated and validated into Portuguese instruments (Multidimensional Anxiety Scale for Children-MASC and Autoquestionnaire Qualité de Vie Enfant Image-AUQEI, respectively). The description and the correlation between the studied variables will be analyzed using descriptive statistics, normality and correlation (Pearson/Spearman) tests and analysis of variance between groups. The psychometric properties of the scales and internal consistency (ceiling and floor effects, Cronbach's alpha coefficient, correlation matrix between items and item-total correlation) and discriminant validity (t-test) will also be assessed. Multiple linear regression models will verify the relationship between anthropometric measurements and nutritional status (as the dependent variables) and scores of quality of life and anxiety, masticatory and salivary function variables and food intake, adjusting for gender, age, orthodontic treatment need and DMFT and dmft index (a = 0.05).
