- ItemComparação entre os fatores associados à resistência à insulina no final da infância e início da adolescência(Universidade Federal do Espírito Santo, 2017-07-28) Pani, Virgilia Oliveira; Barbosa, Miriam Carmo Rodrigues; Faria, Eliane Rodrigues de; Mill, José Geraldo; Alvim, Rafael de OliveiraThe objective of this study was to compare the risk factors associated with the development of insulin resistance (IR) at the end of childhood (8-9 years) and beginning of adolescence (10-14 years) in children and adolescents in the city of Vitória-ES. It is a cross-sectional study with 296 children and adolescents aged 8 to 14 years of public schools in Vitória / ES. Fasting plasma glucose, plasma insulin, total cholesterol and fractions (HDL and LDL), plasma triglycerides (TG), uric acid (AU), C-reactive protein and total leukocytes were determined. IR was assessed by calculating the HOMA-IR index. Measurements of weight, height, waist circumference (WC), perimeter of the neck (PN), perimeter of the hip (PH) and percentage of body fat (%BF) were obtained. Socioeconomic conditions, physical activity practice, eating habits, smoking and alcohol consumption were evaluated. 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 n°. 1.565.490). Of the participants, 54.4% were female and 53.7% were adolescents. The female sex and the adolescence presented greater chances of inadequacy of insulin and IR. Adolescence presented a greater chance of inadequate number of meals, tablet or cellular use, screen time and alcohol consumption. All the anthropometric variables, time on the tablet or cell, time watching television (TV) and total screen time correlated positively with insulin and HOMA-IR. The IR group presented higher values of all the anthropometric variables and most of the biochemical and lifestyle variables, as well as the higher HOMA-IR quartile. Individuals who presented overweight, inadequate WC, PH, PN, Waist / Stature Relationship, excess body fat, inadequate glucose, HDL, TG, TG/HDL ratio, uric acid, insulin, metabolic syndrome, TV, longer screen time, greater family availability of sugar and individuals whose father does not work out were more likely to have IR. In the final model, the excess body fat, the TV watching time above 2h/day and the father did not work out were related to IR in the total sample. In childhood, the TG/HDL ratio ≥p90, AU ≥p90 and the TV watching time was higher than 2h/day and in adolescence the excess body fat, the TV watching time was higher than 2h/day and the family received a government appeal. It was concluded that the risk factors related to IR after 12 adjustments demonstrated different behaviors in the phases evaluated. In this way, it is extremely important to consider the phases separately when evaluating them.
- 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.
- ItemVitamina D e suas novas associações com dados bioquímicos em crianças e adolescentes(Universidade Federal do Espírito Santo, 2023-03-10) Almeida, Pedro Antonio Souza de; Barbosa, Miriam Carmo Rodrigues; https://orcid.org/000000027868572X; http://lattes.cnpq.br/7938843376850281; https://orcid.org/0000-0001-9754-7827; http://lattes.cnpq.br/1461377237255188; Mill, José Geraldo; https://orcid.org/000000020987368X; http://lattes.cnpq.br/2497419234600362; Alvim, Rafael de Oliveira; https://orcid.org/0000-0003-3150-4239; http://lattes.cnpq.br/3204117077254917Introduction: Vitamin D deficiency is a problem that affects various social classes, ages, and genders, and at present, the consequences that inadequate levels of vitamin D can bring to the human body are still unknown. New discoveries about this vitamin further instigate the scientific community to unravel unknown roles of it. Objective: To identify new associations of vitamin D with biochemical markers of health in children and adolescents. Methodology: It is a cross-sectional study developed by data collection and analysis of biochemical and sociodemographic data in children and adolescents enrolled in the institution called Estação do Conhecimento, located in the neighborhood of Cidade Continental, Serra, Espírito Santo. Data analysis was performed with the help of SPSS software version 21.0, and a Pearson correlation test was performed with the collected data to verify if there was an association between the variables, and subsequently, a linear regression test was performed to find out if the relationship was maintained after adjustment for variables that could confound the analysis. Results: A positive correlation was found between vitamin D levels and platelets, where this correlation was maintained after linear regression testing. An association was also found between vitamin D levels and serum transferrin, but there was no association between vitamin D and other markers of iron status. Conclusion: There is a relationship between vitamin D levels and the variables studied here, but further studies are needed to prove if they are indeed interlinked, and new perspectives on the functions of vitamin D in the body are presented here.
