Assessement of nutritional knowledge of individuals normal weight, overweight and obese and its association with nutritional status Introduction: Obesity is defined as a chronic disease, characterized by excessive accumulation of fat and that represents a compromised health. To promote healthier eating habits and, consequently, decrease the rates of obesity, it is believed that it is important that people have knowledge about food and nutrition. Objective: To assess the nutritional knowledge of normal weight individuals, overweight and obese and identify if there is a relationship between nutritional status and nutritional knowledge. Methodology: The sample consisted of 22 individuals classified as eutrophic, 14 classified as overweight and 18 classified as obese according to Body Mass Index, which answered a questionnaire on nutrition knowledge. Results: We observed that, in general, both groups had low and moderate nutrition knowledge. No significant correlations between scores on the questionnaire with the body mass index (r = 0.08) between the questionnaire and educational level (r = 0.29) nor between body mass index and education level (r = - 0.01). Discussion: Improving knowledge does not necessarily imply changes in eating habits. Conclusion: The results suggest that nutrition knowledge does not seem to be a determining factor in food selection. Key words: Nutrition. Obesity. Nutritional Knowledge. Educational Status.

Introduction: Adolescence is a very important period within human development and growth. Objective: To compare the anthropometric measurements according to the stages of maturation of adolescents. Materials and Methods: We evaluated the weight, height, triceps skinfold and subscapular, and sexual maturation. From these data we calculated the IMC and fat percentage, and used the curves of IMC for age and height for age of the WHO (2007). Still, we applied a frequency questionnaire. Results: It was found that 11.8% of boys were overweight and 11.8% obese, and 38% of girls were overweight and 9.5% obese. In relation to sexual maturation stage, most teenagers were in two stages. Regarding the percentage of body fat was found on average higher in girls (19.20 ± 5.58 and 16.66 ± 6.47, respectively). Regarding the food groups, it was found that there is a higher consumption of only 9 groups (beverages), 5 (cereal, breads and tubers) and 8 (meat and eggs) and 3 (milk and dairy products) by adolescents. Conclusion: By what was observed in this study, we conclude that there is a significant presence of overweight and obesity in both adolescents and is more worrying for females. Key Words: adolescents, overweight, obesity, anthropometric.

Introduction: The increase of caloric intake and the reduce of energy expenditure leads to accumulation of energy in the form of fat, increasing the prevalence of chronic non-communicable diseases (NCDs), such as obesity, hypertension, dyslipidemia and diabetes mellitus. Objective: The objective of this study is to show the influence of physical exercise and eating healthy in the control of risk factors associated with metabolic syndrome. Methods and Materials: 33 volunteers were evaluated, equally divided into three groups: diet group (dietary treatment), exercise group (walking three times a week for 45 minutes) and diet + exercise group (dietary treatment with concomitant exercise). Results: The three intervention types of group, led to a decrease in BMI, weight, waist circumference (WC), blood pressure, fasting glucose, total cholesterol, uric acid and C-reactive protein of the volunteers. Discussion: The diet + exercise group showed greater mean reduction of the parameters studied, probably because the increase in calorie deficit, caused by decreased caloric intake associated with increased energy expenditure associated with walking, waist circumference reduced significantly by decreasing visceral fat by improving insulin sensitivity, decreased plasma levels of glucose, reducing blood pressure and triglyceride levels. Conclusion: This study demonstrates that changes in lifestyle, combining exercise and balanced diet contributes to the prevention and / or treatment of Metabolic Syndrome. Key Words: metabolic syndrome, physical activity, dyslipidemia, diet

The prevalence of obesity among young people in Brazil grew by 8.99% and with it the incidence of obesity-related disorders and body image that, depending on the degree of dissatisfaction, can affect aspects of eating behavior, self-esteem and psychosocial performance, physical and cognitive development. Therefore, this work aims to identify the nutritional status and relate it to the perception of body image of adolescents from public schools in São Paulo. The study included 36 adolescents (18 boys and 18 girls) who were evaluated anthropometric and classified BMI according to WHO (1995). We used the scale and EEICA Kakeshita silhouettes. All results were analyzed according to BMI and gender. The questionnaire did not indicate a high degree of dissatisfaction (5.56%). The analysis of the range of silhouettes, we observed overestimation of weight, 50% and 46.47% in the eutrophic and those with BMI lower than expected, respectively, mainly in males (61.12%), and underestimation of overweight adolescents and obese, which demonstrated a desire to lower figure (100%). Among genders, the girls have a closer view of the real (44.44%), however want a figure lower (72.22%) and consider the ideal (61.12%), while the boys consider a higher figure as the ideal (44.44%). Studies show real distortions of perception for both sexes, regardless of the nutritional classification, demonstrating the importance of working the subject since childhood, avoiding discrimination, misconceptions and risks of eating disorders.
