DOI: 10.1590/S1679-45082015AO3339

ObjectiveTo identify biological and psychosocial factors associated with dropout in a multidisciplinary behavioral intervention in obese adolescents.MethodsA total of 183 adolescents (15.4±1.6 years), pubertal (Tanner stage 3 or 4) and obese (34.7±4.0kg/m2), were enrolled in a 12-week behavioral intervention, which included clinical consultations (monthly), nutritional and psychological counseling (once a week), and supervised aerobic training (three times/week). The studied variables were weight, height, body mass index, body composition (skinfold), cardiorespiratory fitness (direct gas analysis), blood lipids and self-reported symptoms of […]

Sexual activity during adolescence can lead to unwanted pregnancy, which in turn can result in serious maternal and fetal complications. The present study aimed to evaluate the complications related to adolescent pregnancy, through a systematic review using the Medical Subject Headings: “pregnancy complication” AND “adolescent” OR “pregnancy in adolescence”. Only full original articles in English or Portuguese with a clearly described methodology, were included. No qualitative studies, reviews or meta-analyses, editorials, case series, or case reports were included. The sample […]

DOI: 10.1590/S1679-45082015AO3226

ObjectiveTo analyze the relation between smoking and passive smoking with heart rate variability parameters in male adolescents.MethodsThe sample consisted of 1,152 males, aged 14 and 19 years. Data related to smoking and passive smoking were collected using a questionnaire. RR intervals were obtained by a heart rate monitor, on supine position, for 10 minutes. After collecting the RR intervals, time (standard deviation of all RR intervals, root mean square of the squared differences between adjacent normal RR intervals and the […]

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 […]

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 […]

ABSTRACT Objective: To establish the clinical aspects of growing pains and to determine, through differential diagnosis, how many patients who referred themselves to a specialized clinic were found to have growing pains. Methods: This study prospectively examined the presence of growing pains in a self-reported population of children and adolescents with signs and symptoms (lower limb pains) of unexplained etiology. Results: A total of 345 children and adolescents were evaluated; 174 (50.4%) were males and 171 (49.6%) were females. Three […]

DOI: 10.1590/s1679-45082010ao1361

ABSTRACTObjectiveTo evaluate bone mineral mass in adolescents with failure to thrive in relation to body composition.MethodsA case control study involving 126 adolescents (15 to 19 years), in final puberty maturation being 76 eutrophic and 50 with failure to thrive (genetic or constitutional delay of growth), of matching ages, gender and pubertal maturation. The weight, height and calculated Z score for height/age and body mass index; bone mineral content, bone mineral density and adjusted bone mineral density were established for total […]
