ABSTRACT Objective: To study associations between polymorphisms in the angiotensin converting enzyme (ACE I/D), actinin 3 (ACTN3 R577X) and paraoxonase 1 (PON1 T(-107)C) genes and chronic diseases (diabetes and hypertension) in women. Materials and methods: Genomic DNA was extracted from saliva samples of 78 women between 18 and 59 years old used for genetic polymorphism screening. Biochemical data were collected from the medical records in Basic Health Units from Southern Brazil. Questionnaires about food consumption, physical activity level and socioeconomic […]

ABSTRACT Objective: This study investigated the nutritional status, 25-hydroxyvitamin D (25OHD), albumin and risk factors associated with complications in patients with foot and ankle fragility fractures. Subjects and methods: Prospective study, developed with patients who suffered fractures due to fragility of the foot and ankle (n = 108); the type of fractured bone, fracture mechanisms and classification were studied and also pseudoarthrosis, treatment, surgical dehiscence, anthropometry, 25OHD and albumin. The Chi-square or Fisher’s exact test, Mann-Whitney and Kruskal-Wallis tests were […]

Abstract Objective: Arterial hypertension (AH) is a risk factor for cardiovascular diseases (CVD). We sought to evaluate the association between two adiposity indices (visceral adiposity index [VAI] and lipid accumulation product [LAP]) with traditional markers of cardiometabolic risk in hypertensive patients. Materials and methods: This is a cross-sectional study with 1,273 subjects with hypertension treated as outpatients at a university hospital. The VAI and LAP were calculated using formulas stratified by sex. Cardiometabolic risk variables were considered: overweight, risk for […]

ABSTRACT Objective This study aimed to determine the prevalence and the temporal trend in overweight, as well as their relationship with sociodemographic factors in adolescents from northeastern Brazil. Subjects and methods We analyzed data from two similar school-based, cross-sectional epidemiological studies conducted in 2005 (n = 2,768) and 2009 (n = 2,776), with public and private high school students of both sexes, aged 14 to 18 years, in João Pessoa, state of Paraiba, Brazil. Sociodemographic information (sex, age and economic […]

OBJECTIVE: To identify the association of socioeconomic, demographic, nutritional and of physical activity factors in the glycemic control of adolescents with T1DM. SUBJECTS AND METHODS: Sectional study of 71 adolescents with type 1 diabetes. Socioeconomic, demographic and anthropometric data were obtained. The glycemic control was classified by the index of glycated hemoglobin (A1C). Four 24-hours recalls of food consumption and physical activity were applied. RESULTS: The A1C was inadequate for the majority of the adolescents. The low educational level of […]

Nutritional disorders (undernutrition and obesity) are associated to increases in morbidity and mortality. This paper consists on a review of literature with the purpose of describing the main methods of nutritional assessment, in order to facilitate the diagnosis of nutritional disorders and the follow-up of dietetics interventions. It describes the clinical method, details procedures of anthropometry and laboratory evaluation and enrolls some of the multiple indices used for diagnosis and prognosis. Information about bioelectric impedance is given. Some aspects of […]

This review reports the etiological aspects of insulin resistance as well as the participation of zinc in this process. Zinc participates in the metabolic pathways involving protein synthesis, and the metabolism of carbohydrate, lipid and nucleic acid. This element has been associated with the interaction between hormones and their receptors and to the improvement in the post-receptor stimulus. In vitro studies show that insulin may form a complex with zinc improving the solubility of this hormone in the pancreatic b […]

This study was aimed to determine the prevalence of obesity among adolescents who attend State Schools in the city of Bragança Paulista (SP), and its relationship with parental nutritional status. This was a cross-sectional study involving 1,334 adolescents (796 [59.7%] female), ranging in age from 11 to 18 years, regularly registered in the 5th through the 12th grade. The following variables were studied: sex, age, current weight and height (in the adolescents and parents) and educational level (in the adolescents). […]
