ABSTRACTObjectiveTo evaluate effects of overweight on spirometric parameters in adolescents who underwent bronchial provocation test for exercise.Methods We included 71 male adolescents. The diagnosis of asthma was done based on participants’ clinical history and on the International Study Questionnaire Asthma and Allergies in Childhood, and the diagnosis of obesity was based on body mass index above 95th percentile. The bronchospasm induced by exercise was assessed using the run-walk test on a treadmill for eight minutes. The decrease in forced expiratory […]

DOI: 10.1590/S1679-45082015AO3344

ObjectiveTo investigate the clinicopathological findings of women diagnosed with breast cancer and study the impact of chronic psychological stress on the pathological characteristics of these tumors.MethodsWe investigated a cohort composed of women diagnosed with breast cancer and divided into two groups. One group was categorized as presenting with chronic psychological stress (by using the Self-Reporting Questionnaire − SRQ-20). Another group of women with breast cancer, but with no previous history of chronic psychological stress, comprised the Control Group. Clinical and […]

DOI: 10.1590/S1679-45082014AO3214

ObjectiveTo compare the total and differential leukocyte count in obese and normal-weight adolescents, and to verify their possible relations with cardiorespiratory fitness and adiposity indicators.MethodsA cross-sectional study conducted with 139 adolescents (107 obese and 32 normal weight) aged between 13 and 18 years. Cardiorespiratory fitness was determined by direct gas analysis during an incremental treadmill test. Total leukocytes and subsets were estimated by flow cytometry. Body composition was assessed by dual-energy X-ray absorptiometry. Thet-test for independent samples was used for […]

Analysis of endometrial thickness measured by transvaginal ultrasonography in obese patients

Isabela Corrêa Barboza, Daniella de Batista Depes, Ilzo Vianna Júnior, Marisa Teresinha Patriarca, Raquel Martins Arruda, João Alfredo Martins, [...]

DOI: 10.1590/S1679-45082014AO2838

ObjectiveTo compare the endometrial echo values obtained by transvaginal ultrasonography with the body mass index of postmenopausal patients; to verify if there is higher prevalence of endometrial thickening in women with body mass index ≥30.MethodsThis is an analytical and cross-sectional study that evaluated 294 patients. Postmenopausal women were included, and those on hormone therapy were excluded. The variables evaluated were body mass index (considering obesity if >30), number of pregnancies, years since menopause, and age. These variables were correlated with […]

Effects of different intensities of physical exercise on insulin sensitivity and protein kinase B/Akt activity in skeletal muscle of obese mice

Rodolfo Marinho, Leandro Pereira de Moura, Bárbara de Almeida Rodrigues, Luciana Santos Souza Pauli, Adelino Sanchez Ramos da Silva, Eloize Cristina Chiarreotto Ropelle, [...]

DOI: 10.1590/S1679-45082014AO2881

Objective:To investigate the effects of different intensities of acute exercise on insulin sensitivity and protein kinase B/Akt activity in skeletal muscle of obese mice.Methods: Swiss mice were randomly divided into four groups, and fed either a standard diet (control group) or high fat diet (obese sedentary group and obese exercise group 1 and 2) for 12 weeks. Two different exercise protocols were used: swimming for 1 hour with or without an overload of 5% body weight. The insulin tolerance test […]

Obesity is a chronic disease characterized by the excessive accumulation of body fat that is harmful to the individuals. Respiratory disorders are among the comorbidities associated with obesity. This study had the objective of investigating the alterations in respiratory function that affect obese individuals. A systematic review was performed, by selecting publications in the science databases MEDLINE and LILACS, using PubMed and SciELO. The articles that assessed pulmonary function by plethysmography and/or spirometry in obese individuals aged under 18 years […]

Excess weight in employees of food and nutrition units at a university in São Paulo State

Juliano dos Santos, Aline Alves Ferreira, Karina Cardoso Meira, Angela Maria Geraldo Pierin

DOI: 10.1590/S1679-45082013000400014

Objective:To describe the prevalence and identify the factors associated with excess weight in restaurant employees at a public university in the city of São Paulo.METHODS:A socioeconomic and nutritional census was conducted with 174 individuals to obtain data on body mass, height, and socioeconomic status, using a structured questionnaire. The body mass index was determined, and the cut-off points recommended by the World Health Organization were used. Student’s t test, Fisher’s exact test, and the χ² test were used to verify […]

Short-term effects of moderate intensity physical activity in patients with metabolic syndrome

Caroline Macoris Colombo, Rafael Michel de Macedo, Miguel Morita Fernandes-Silva, Alexandra Moro Caporal, Andréa Emilia Stinghen, Costantino Roberto Costantini, [...]

DOI: 10.1590/S1679-45082013000300011

OBJECTIVES:To evaluate whether a short-term moderate intensity exercise program could change inflammatory parameters, and improve different components of metabolic syndrome in sedentary patients.METHODS:Sixteen patients completed the 12-week program of supervised exercise, which consisted of a 40 to 50 minutes of walking, 3 times a week, reaching 50 to 60% of the heart rate reserve. The parameters evaluated before and after intervention were waist circumference, systolic and diastolic blood pressure, triglycerides, LDL cholesterol, HDL cholesterol, total cholesterol, C-reactive protein and interleukin […]

Heart rate variability and its relationship with central and general obesity in obese normotensive adolescents

Breno Quintella Farah, Wagner Luiz do Prado, Thiago Ricardo dos Santos Tenório, Raphael Mendes Ritti-Dias

DOI: 10.1590/S1679-45082013000300005

Objective:To analyze the relationship between the heart rate variability parameters and the indicators of central and general obesity in obese normotensive adolescents.METHODS:Seventyfour 13 to 18 year-old obese normotensive adolescents participated in this study. The indicators analyzed for central and general obesity were waist circumference and body mass index, respectively. Heart rate variability was obtained by heart rate monitoring. For this, the adolescents remained in a supine position for 7 minutes with controlled breathing. Parameters were obtained in time domain (standard […]

Objective:To investigate the prevalence of appetite suppressant use among health sciences students in Southern Brazil.METHODS:Undergraduate students (n=300) from seven health science undergraduate courses of the Universidade de Caxias do Sul completed a questionnaire about the use of substances to suppress appetite.RESULTS:A significant percentage (15%; n=45) of research participants used appetite suppressants at least once in their lives. The most commonly used substances were sympathomimetic stimulant drugs (5%), including amfepramone (3.3%) and fenproporex (1.7%). The lifetime use of appetite suppressants was […]
