- ItemÁcido úrico e fatores de risco cardiovasculares no final da infância e início da adolescência(Universidade Federal do Espírito Santo, 2018-10-01) Peçanha, Marcos Alves de Souza; Barbosa, Miriam Carmo Rodrigues; Faria, Eliane Rodrigues de; Pereira, Taísa Sabrina Silva; Leopoldo, Ana Paula Lima; Oliveira, Elizabete Regina Araújo de; Leopoldo, André SoaresThe aim of this study was to investigate the relationship between uric acid and cardiovascular risk factors at the end of childhood (8-9 years) and early adolescence (10-14 years), of schoolchildren in the region of Maruípe in the municipality of Vitória-ES. This is a cross-sectional, observational, convenience study with 296 children and adolescents, of both sexes, from 9 public schools in the city of Vitória-ES. Anthropometric, hemodynamic and biochemical assessments were performed (Fasting of 12 h), blood collection was used to determine fasting glycemia, plasma insulin, total cholesterol and fractions (HDL and LDL), triglyceride plasmatic (TGC), uric acid (UA), plasma insulin, C-reactive protein and total leukocytes. Insulin resistance was evaluated by calculating the HOMA-IR index. Measurements of weight, height, waist circumference (WC), hip perimeter (HP) and body fat percentage (%BF) were obtained. In the evaluation for uric acid, the values above the 90 percentile were considered high according to each phase and sex. Statistical analyses were performed using the Kolmogorov-Smirnov test, chi-square test or Fischer exact test, Mann Whitney test, Pearson or Spearman correlation, and simple and multiple logistic regression models. The significance level adopted was p < 0.05. The project was approved by the Ethics Committee on Research with human beings of the Federal University of Espírito Santo (Opinion n° 1.565.490) and the term of free and informed consent was signed by the participants and their guardians. It was observed that the sample consisted of 54,4% (n = 161) Females, with mean age 10,7 ± 2,0 years and 54,0% (n = 159) were adolescents. When assessing the prevalences of anthropometric inadequacies and body composition according to the uric acid classification according to the phases, both in childhood and adolescence, overweight, WC, HP, waist-to-height ratio (WHR) and excess body fat showed higher prevalence in relation to elevated uric acid, and in biochemical and clinical alterations. In childhood, significance was manifested in HDL, insulin and insulin resistance, and in adolescence with blood pressure, LDL, insulin and insulin resistance. The correlation between uric acid levels and body composition, biochemical and clinical, were moderate in childhood with weight, WHR, HP, %BF, and negatively with HDL. Simple regression in childhood indicated that BMI, WC, HP, WHR, %BF, elevated Homa-IR index and low HDL, and in adolescence BMI, HP, WHR, %BF, blood pressure (BP), LDL and Homa-IR index showed a higher chance of presenting elevated uric acid. In the multiple logistic regression model for removal of the effect, it was observed that no variable remained associated. It was concluded that children and adolescents with elevated uric acid did not present association for cardiovascular risk factors. However, higher uric acid values were noted in the individuals evaluated with inadequate anthropometric and body composition parameters.
- ItemFatores associados à insatisfação corporal no final da infância e início da adolescência(Universidade Federal do Espírito Santo, 2018-02-27) Martins, Caroline Resende; Barbosa, Miriam Carmo Rodrigues; Faria, Eliane Rodrigues de; Alvim, Rafael de Oliveira; Mill, Jose Geraldo; Soares, Fabíola Lacerda Pires; Leopoldo, Ana Paula LimaThe objective of this study was to identify factors associated with body dissatisfaction at the end of childhood (8-9 years) and beginning of adolescence (10-14 years) in children and adolescents in the Maruípe region of the city of Vitória-ES. It is an observational, cross-sectional study with 296 children and adolescents aged 8 to 14 years of public schools in Vitória / ES. To evaluate the biochemical profile, after a 12- hour fast, 10 mL of blood was collected for the determination of fasting glycemia, plasma insulin, total cholesterol and fractions (HDL and LDL), plasma triglycerides (TGC), acid uric acid (AU), plasma insulin, C-reactive protein and total leukocytes. Insulin resistance was assessed by calculating the HOMA-IR index. Measurements of weight, height, waist circumference (WC), neck circumference (NC), hip circumference (HC) and body fat percentage (% BF) were obtained. Body dissatisfaction was assessed through the Kakeshita silhouettes scale, as well as questions from the Body Shape Questionnaire (BSQ) were used to evaluate eating behaviors. Socioeconomic conditions, physical activity, eating habits, race / color, smoking and alcohol consumption were also evaluated. Sexual maturation was assessed through the selfassessment proposed by Tanner. A subsample for the screening of eating disorders was carried out using the Edinburgh Bulimia Research Test (BITE) and Food Attitude Test (EAT) tests. We used the Shapiro Willk Normality Test, non-parametric tests and simple and multiple logistic regression models. The project was approved by the Human Research Ethics Committee of the Federal University of Espírito Santo (opinion No. 1,565,490) and the Informed Consent Form and Assent was signed by the participants and their officials. It was observed that 88.8% (n = 263) of the sample was dissatisfied with body image, with the desire to lose weight in girls (68.5%) (p <0.0001) and to gain weight in the boys (35.1%) (p <0.0001). In girls, the prevalence of high triglycerides, high fasting insulin and insulin resistance were significantly higher than in boys. No group of dissatisfied ones such as prevalence of overweight, excess body fat, high WC, elevated CRF, high fasting insulin and high waist height ratio (WHR) were greater than satisfied. In the sub-sample, it was possible to observe that the prevalence of individuals who presented positive screening for anorexia nervosa was higher than that of the unsatisfied group (p <0.05). In the simple regression it was observed that overweight, WHR, inadequate% BF, high plasma insulin and cigarette use were associated with body dissatisfaction, presenting different behaviors according to stage and sexual maturation. However, only overweight remained in the final model, in early adolescence and in the final stages of sexual maturation. It is concluded that overweight was the main factor associated with body dissatisfaction in the children and adolescents of this study, being essential the evaluation of the life stage and the degree of maturation that these are.
