Stage to Change Eating behavior and physical activity among adolescents with an excess body mass: impact on metabolic profile / Prontidão para a mudança do comportamento alimentar e atividade física entre adolescentes com excesso de peso: impacto no perfil metabólico

INTRODUCTION: Obesity in children and adolescents is usuallyrelated to metabolic alterations, and intervention programs are one of the strategies for the treatment of obesity and associated comorbidities. At the beginning of the intervention, the stages of readiness to change behavior indicate specific habits that the teenager plans to modify or not, and how long he or she intends to make the alterationsOBJECTIVE: To assess the metabolic profile and their association with the stages of readiness to change eating habits and exercise behaviors in adolescents with overweightMETHODS: Eighty-three adolescents with excess body weight underwent an assessment of anthropometric variables and metabolic profile (glucose, total cholesterol, LDL-c, HDL-c, non-HDL-c, VLDL, triglycerides, insulin). Besides, the stages of readiness to change behaviors for "size and amount of portions," "amount of fat in the diet," fruits and vegetable consumption," and "physical activity practice," anthropometric variables and metabolic profile were compared according to the stages of changeRESULTS: About "fruits and vegetable consumption," adolescents in the Maintenance group presented lower body weight than those from Action and Preparation groups. The Action group presented higher body weight than group "Contemplation" and it showed higher non-HDL-cholesterol than the groups "Pre-contemplation" and "Preparation." In "physical activity practice," the Maintenance group presented lower body weight, Body Mass Index, and body fat (in kg) than Action, Preparation, and Contemplation groups. The alterations in HDL-cholesterol reduced as the stages of change progressed in the "physical activity practice" domainCONCLUSION: The stages of readiness to change behaviors impact anthropometric and metabolic variables in adolescents with excess body weight, and it is a recommended instrument to monitor intervention programs

INTRODUÇÃO: A obesidade em crianças e adolescentes geralmente está relacionada com alterações metabólicas, sendo os programas de intervenção uma das estratégias para o tratamento da obesidade e das comorbidades associadas. Ao iniciar a intervenção, os estágios de prontidão para mudança do comportamento indicam hábitos específicos que o adolescente planeja ou não mudar e em quanto tempo ele pretende realizar a mudançaOBJETIVO: Avaliar o perfil metabólico e sua associação com os estágios de prontidão para mudança do comportamento alimentar e atividade física em adolescentes com excesso de pesoMÉTODO: Foram avaliados 83 adolescentes com excesso de peso. Os adolescentes foram avaliados em relação à variáveis antropométricas e perfil metabólico (glicemia, colesterol total, colesterol LDL, HDL, não-HDL, VLDL, triglicerídeos, insulina). Além disso, foram avaliados os estágios de prontidão para mudança do comportamento para os domínios "tamanho e quantidade das porções", "quantidade de gordura na dieta", "consumo de frutas e vegetais" e "prática de atividade física". Foi feita comparação das variáveis antropométricas e perfil metabólico de acordo com os estágios de prontidãoRESULTADOS: Em relação ao domínio "Consumo de Frutas e Vegetais", os adolescentes do grupo Manutenção apresentaram peso menor que os do grupo Ação e Preparação. O grupo Ação apresentou peso maior que o Contemplação, e o grupo Contemplação apresentou colesterol não-HDL maior que os grupos Pré-contemplação e Preparação. No domínio "Prática de Atividade Física", o grupo Manutenção apresentou peso, IMC e gordura corporal (em kg) menores que os grupos Ação, Preparação e Contemplação. A prevalência de alteração do colesterol HDL foi progressivamente menor conforme progrediram os estágios de prontidão para mudança do comportamento para o domínio "prática de atividade física"CONCLUSÃO: Os estágios de prontidão para mudança do comportamento têm impacto sobre variáveis antropométricas e perfil metabólico de adolescentes com excesso de peso, sendo um instrumento recomendado para o monitoramento de programas de intervenção

Building a response criterion for pediatric multidisciplinary obesity intervention success based on combined benefits.

To propose a response criterion for analyzing the intervention success by verifying patient outcomes after a multidisciplinary obesity treatment program in Brazilian children and adolescents. Obese children and adolescents (n = 103) completed a 16-week multidisciplinary intervention (IG) and were compared to the control group (CG) (n = 66). A cluster of parameters (e.g. total domain of HRQoL; BMI z-score; cardiorespiratory fitness; body mass; waist circumference; fat mass; lean mass) were measured pre and post-intervention, and the sum of the median percentage variation and the percentile 25 and 75 were used from IG and CG to determine the responsiveness to the program. We are proposing four ranges in which children and adolescents may be classified after the intervention: (1) CG percentile 50 values or lower are considered non-responsive to the intervention, (2) values greater than CG percentile 50 but lower than IG percentile 50 are considered slightly responsive, (3) values greater than IG percentile 50 but lower than IG percentile 75 were considered as moderately responsive, and (4) values greater than IG percentile 75 were considered very responsive. CONCLUSIONS: This criterion may serve as a complementary tool that can be employed to monitor the response to this model of multidisciplinary intervention. What is Known: • The effectiveness of multidisciplinary obesity interventions is usually determined by comparing changes in selected outcomes in the intervention versus versus control group. • There is no consensus about what should be assessed before and after the intervention program, which makes difficult to compare different programs and to determine their rate of responsiveness. What is New: • This study proposes a response criteria to pediatric obesity interventions following a similar model compared to ours based on key variables that presents low cost and high applicability in different settings.

Intervenção multiprofissional melhora a aptidão física relacionada à saúde de adolescentes com maior efeito sobre as meninas em comparação aos meninos / Multiprofessional intervention improves health-related physical fitness in adolescents with greater effect on girls compared to boys

Resumo Este estudo teve como objetivo verificar as diferenças entre as respostas de meninos e meninas a um programa multiprofissional de tratamento da obesidade sobre a aptidão física relacionada à saúde. Fizeram parte do estudo 163 adolescentes com excesso de massa corporal e idade entre 10 e 18 anos. Foram avaliados parâmetros antropométricos, composição corporal, flexibilidade, força e resistência abdominal e aptidão cardiorrespiratória antes e após 16 semanas de intervenção multiprofissional. A intervenção multiprofissional contou com a participação de profissionais de educação física, nutrição, psicologia e pediatria e teve como foco principal o incentivo a mudanças nos hábitos alimentares e de atividade física que pudessem promover alterações positivas nos parâmetros analisados. A intervenção teve frequência semanal de três sessões, sendo uma hora de intervenções teóricas com os profissionais de educação física, nutrição e psicologia e a outra hora destinada à prática regular de exercícios físicos, com predominância de exercícios físicos resistidos, aeróbios e prática de basquetebol. Após a intervenção tanto as meninas quanto os meninos apresentaram melhoras significativas nas variáveis IMC, circunferência de cintura e quadril, massa gorda relativa e absoluta, massa magra, flexibilidade, força/resistência abdominal e aptidão cardiorrespiratória, porém com resultados mais expressivos para as meninas sobre a circunferência de cintura, gordura corporal (kg), VO2max e força/resistência abdominal.(AU)

Abstract This study aimed to verify the differences between both boys and girls responses to a multidisciplinary program of obesity treatment on health-related physical fitness. One hundred and sixty three adolescents with excess body weight and aged 10 to 18 years took part in the present study. It was assessed anthropometric parameters, body composition, flexibility, abdominal strength/resistance and cardiorespiratory fitness before and after 16 weeks of a multiprofessional intervention. The multiprofessional intervention was developed by physical educators, nutritionist, psychologist, pediatrician and was focused on motivate eating and exercise changes which could promote positive changes on the parameters analyzed. The intervention was conducted three times per week in which theoretical intervention lasted one hour with physical educators, nutritionist and psychologist and another hour designated to practical interventions of the physical educators in which predominated resistance and aerobic exercise as well as basketball practice. After the intervention, both girls and boys presented significant improvements in BMI, waist and hip circumference, relative and absolute body fat, lean mass, flexibility, strength and resistance in abdominal and cardiorespiratory fitness; however the results were more expressive for girls on waist circumference, body fat (kg), VO2max and abdominal strength/resistance.(AU)

Effect of water- versus land-based exercise training as a component of a multidisciplinary intervention program for overweight and obese adolescents.

To compare water- versus land-based exercise programs, as part of a multidisciplinary intervention, on physical fitness and health-related quality of life in overweight and obese adolescents. A total of 151 overweight and obese adolescents (age: 13.2±1.8years) were divided into: 1) a water-based intervention (WB; n=28); 2) a land-based intervention (LB; n=57); and 3) a control group (CG; n=66). Anthropometric measures, body composition, flexibility, abdominal strength/endurance, cardiorespiratory fitness and health-related quality of life were assessed prior and by the end of a 16-week intervention. Both the water- and land-based interventions were part of a multidisciplinary program focusing on behavioral changes. Fat Mass (%) was significantly reduced in both intervention groups and a higher progression was observed in the WB group (-9.8±7.2% versus -6.1±6.2%; p<0.05 for pre-to-post changes within-groups). However, LB increased more abdominal strength than WB (69.6±165.8% versus 53.4±83.4%; p<0.05) and significantly increased social (19.7±88.8%), psychosocial (5.1±15.1%) and total score (6.3±14.8%), which was observed in neither WB nor CG. The intervention groups did not change body weight (WB: -1.7±5.3%; LB: 0.1±3.4%; p>0.05 for both groups) and increased (p<0.05) fat-free mass (WB: 4.6±4.0%; LB: 4.4±4.1%), VO2max (WB: 9.3±7.8%; LB: 11.0±13.4%), and physical dimension of quality of life (WB: 9.2±17.2%; LB: 8.9±18.0%) differently of what was observed in CG. The physical dimension improvement observed in the land-based and water-based samples was associated with decreased percentage fat mass (r=0.282 and 0.229; p<0.05). We suggest water- and land-based physical exercises within a multidisciplinary program promote similar improvements in body composition, physical fitness and health-related quality of life in overweight and obese adolescents.

Efeitos de um programa multiprofissional de tratamento da obesidade sobre o hábito e a frequência alimentar em adolescentes: diferenças entre sexos / Effects of a multiprofessional program for treatment of obesity on feeding behavior and frequency in adolescents: differences between sexes

Objetivo: Avaliar os efeitos de um Programa Multiprofissional de Tratamento da Obesidade (PMTO) sobre os hábitos alimentares de adolescentes de ambos os sexos. Métodos: Fizeram parte do estudo 53 adolescentes com excesso de peso, com idades entre 11 e 18 anos, sendo 30 meninas. A análise dos hábitos alimentares foi feita a partir do questionário de frequência alimentar e recordatório alimentar de 24 horas. Foram reportados dados referentes a oito semanas de intervenção. Resultados: Foi observada redução do consumo de doces (p=0,011) por parte das meninas, e de macarrão (p=0,039) e ovos (p=0,040) pelos meninos. Houve redução no valor calórico total nas meninas (p=0,006). O grupo feminino também demonstrou redução do consumo absoluto de carboidratos (p=0,016), proteínas (p=0,035), lipídios (p=0,018) e lipídios poli-insaturados (p=0,011). Quanto aos micronutrientes, houve redução no consumo de sódio (p=0,003) no mesmo grupo. Conclusão: Mudanças nos hábitos alimentares foram observadas em maior proporção no sexo feminino.

Objective: The aim of the present study was to assess the effects of a Multiprofessional Program of Obesity Treatment (PMTO) on feeding habits in male and female adolescents. Methods: In this study 53 adolescents with excess of weight aged from 11 to 18 years old, 30 girls, were included. The analysis of feeding habits was made with a food frequency questionnaire and a 24 hours recall. It was reported data related to eight weeks of intervention. Results: We observed reduction in candies consumption (p=0.011) in girls, and pasta (p=0.039) and eggs (p=0.040) in boys. Total energy intake decreased in girls (p=0.006). The female group also demonstrated reduction of carbohydrates (p=0.016), proteins (p=0.035), fat (p=0.018) and polyunsaturated fat (p=0.011). In relation to micronutrients, sodium consumption was decreased (p=0.003) in the same group. Conclusions: Changes in feeding habits were greater in girls.

Impact of readiness to change behavior on the effects of a multidisciplinary intervention in obese Brazilian children and adolescents.

The obesity epidemic is a global challenge that requires evidence-based intervention to slow the emergence of weight-related illness in children and adolescents. Thus, effective treatments are urgently needed. This study aimed to analyze whether there is relationship between the initial stage of readiness for behavior change (SRBC) and the results obtained through participation in a multidisciplinary program of obesity treatment (MPOT). The study included 113 overweight or obese children and adolescents who participated in an intervention for 16 weeks, in which the categorical variable was the SRBC. The dependent variables included: anthropometric measures of body composition, hemodynamic parameters (e.g., blood pressure values), and health-related physical fitness. Although stages 1 and 2 had greater improvements in flexibility than those in stage 5, and stage 1 had greater percentage changes in abdominal strength than those in stage 5, children and adolescents in the highest stage had greater percentage changes for anthropometric, hemodynamic and cardiorespiratory fitness, suggesting an impact of the stage of change on the effects of a MPOT. This study suggests that SRBC plays a role in obesity treatment in Brazilian children and adolescents and warrants consideration when enrolling patients to intervention.

[Physical, clinical, and psychosocial parameters of adolescents with different degrees of excess weight]. / Parâmetros físicos, clínicos e psicossociais de adolescentes com diferentes graus de excesso de peso.

OBJECTIVE: To compare body composition, hemodynamic parameters, health-related physical fitness, and health-related quality of life of adolescents with anthropometric diagnosis of overweight, obesity, and severe obesity. METHODS: 220 adolescents with excess body weight were enrolled. They were beginners in a intervention program that included patients based on age, availability, presence of excess body weight, place of residence, and agreement to participate in the study. This study collected anthropometric and hemodynamic variables, health-related physical fitness, and health-related quality of life of the adolescents. To compare the three groups according to nutritional status, parametric and non-parametric tests were applied. Significance level was set at p<0.05. RESULTS: There was no significant difference in resting heart rate, health-related physical fitness, relative body fat, absolute and relative lean mass, and health-related quality of life between overweight, obese, and severely obese adolescents (p>0.05). Body weight, body mass index, waist and hip circumference, and systolic blood pressure increased as degree of excess weight increased (p<0.05). Dyastolic blood pressure of the severe obesity group was higher than the other groups (p<0.05). There was an association between the degree of excess weight and the prevalence of altered blood pressure (overweight: 12.1%; obesity: 28.1%; severe obesity: 45.5%; p<0.001). The results were similar when genders were analyzed separately. CONCLUSION: Results suggest that overweight adolescents presented similar results compared to obese and severely obese adolescents in most of the parameters analyzed.

Factors associated with bone mineral density in women who underwent bariatric surgery / Fatores associados à densidade mineral óssea em mulheres submetidas à cirurgia bariátrica

To analyze factors associated with bone mineral density (BMD) of candidates and patients admitted to Bariatric Surgery (BS). This study included 61 women who had done or were waiting for BS. Anthropometric variables, body composition and BMD from the femur, femoral neck, lumbar spine and the whole body were measured. The factors associated with changes in BMD, such as smoking, alcohol ingestion, sedentary lifestyle, BS, nutritional supplementation and age were evaluated. The statistical significance was set at 5%. Age and BS were associated with changes in BMD. Among the individuals who had BS done, the rates of osteopenia/osteoporosis were greater in the femur (OR 3.34; CI [1.52 - 1.83]) and femoral neck (OR 3.69; CI [1.34 ­ 2.08]). Subjects older than 50 years also had greater rates of BMD in the lumbar spine (OR 4.12; CI [2.09 ­ 22.33]), the whole body (OR 4.77; CI [1.34 ­ 28.14]), femur (OR 16.94; CI [2.16 - 124.32]) and femoral neck (OR 14.95; CI [1.86 - 110.66]). Patients who have had BS and are over 50 years of age showed higher rates of osteopenia/osteoporosis, which demonstrate the necessity of further studies exploring the effects of BS and its impact on bone metabolism.

Analisar fatores associados à densidade mineral óssea (DMO) de candidatas e de pacientes submetidas à cirurgia bariátrica (CB). Neste estudo transversal foram avaliadas variáveis antropométricas, composição corporal e DMO do fêmur, colo do fêmur, coluna lombar e corpo inteiro, além dos fatores associados às alterações na DMO: tabagismo, consumo de álcool, sedentarismo, CB, suplementação e idade em 61 mulheres com média de idade de 43,97 (± 10,73) anos. Significância pré estabelecida em 5%. A idade e CB apresentaram associação com alterações na DMO. Os sujeitos operados apresentaram maiores chances de apresentar osteopenia/osteoporose no fêmur (RC 3,34; IC [1,52 ­ 1,83]) e no colo do fêmur (RC 3,69; IC [1,34 - 2,08]) e os sujeitos com idade superior a 50 anos apresentaram maiores chances de apresentar alterações na DMO na coluna lombar (RC 4,12; IC [2,09 - 22,33]), no corpo inteiro (RC 4,77; IC [1,34 - 28,14]), fêmur (RC 16,94; IC [2,16 ­ 124,32]) e no colo do fêmur (RC 14,95; IC [1,86 ­ 110,66]). Pacientes submetidos à CB e com idade superior a 50 anos apresentam maiores alterações na DMO, demonstrando a importância de mais estudos que explorem os efeitos da CB e suas repercussões sobre o metabolismo ósseo.

Comparação entre equipamentos de impedância bioelétrica bipolar e octapolar para a estimativa da massa livre de gordura e da gordura relativa em adolescentes com sobrepeso e obesidade / Comparison between bipolar and octapolar bioelectrical impedance analyzer for estimating fat free mass and relative fat in overweght and obese adolescents

O objetivo do estudo foi comparar equipamentos de impedância bioelétrica bipolar (IB2) (frequência: 50Hz) e octapolar (IB8) (frequência: 5, 50 e 500Hz) para a estimativa da massa livre de gordura (MLG) e da gordura relativa (G%), antes e após 16 semanas de intervenção, em adolescentes com sobrepeso e obesidade. A MLG e a G% foram medidas por meio da IB2 e da IB8, antes e após 16 semanas de intervenção multiprofissional focada na mudança de comportamento alimentar e atividade física. A MLG e a G% obtidas nas IBs foram comparadas pela ANOVA de medidas repetidas e correlacionadas através da Correlação de Pearson. Foram observadas diferenças (p<0,05) entre os equipamentos para a estimativa da MLG e G% apenas no momento pré intervenção nas meninas. Concluiu-se que as estimativas da MLG e da G% não foram estatisticamente diferentes pelos dois equipamentos (octapolar e bipolar), bem como a variação dessas duas variáveis.

The aim of this study was to compare bipolar (BI2) (frequency: 50Hz) and octapolar (BI8) (frequency: 5, 50 e 500Hz) bioelectrical impedance analyzers to estimate fat-free mass (FFM) and relative body fat (BF%) before and after 16 weeks of intervention in overweight and obese adolescents. The FFM and BF% were measured by BI2 and BI8 before and after 16 weeks of multidisciplinary intervention focused on changing eating and exercise habits. FFM and BF% obtained in the IBs were compared by ANOVA for repeated measures and correlated by Pearson Correlation Coefficient. Differences (p<0.05) were observed between the analyzers for the estimation of FFM and BF% only in the pre intervention moment for the girls. We conclude that the estimations of FFM and BF% were not significantly different between the two BI (octapolar and bipolar), especially for the variation of these two variables.

Parasympathetic cardiac activity is associated with cardiorespiratory fitness in overweight and obese adolescents.

The aim of this study was to investigate the association between cardiac parasympathetic activity and cardiorespiratory fitness, insulin, and hemodynamic profile in overweight and obese adolescent girls and boys (aged 12-16 years). Data were taken from the Multidisciplinary Obesity Treatment Program. Only post-intervention measurements are presented herein. Body composition, cardiorespiratory fitness, blood pressure, and metabolic profile (insulin and glucose profile) of adolescents were assessed. Cardiac parasympathetic activity was determined by resting heart rate variability, which was analyzed using a heart rate monitor. Greater parasympathetic cardiac activity was associated with higher levels of cardiorespiratory fitness in both girls and boys (0.375 ≤ r ≤ 0.900), while the sympathetic-vagal balance was negatively related to maximal oxygen uptake (VO2max) in girls (r = 0.478). An association between lower parasympathetic activity and insulin resistance was noted in girls (mean of R-R intervals [RRmean] and homeostasis model assessment insulin-resistance index [HOMA-IR]: r = -0.678), while greater systolic blood pressure (SBP) and lower parasympathetic activity were associated in both sexes (RRmean and SBP: r = -0.526; high frequency [HF (nu)] and SBP: r = -0.754). In conclusion, autonomic nervous system activity was associated with cardiorespiratory fitness, insulin resistance, and SBP in overweight and obese adolescents. The identification of these potential relationships assists with the establishment of future long-term exercise interventions that evaluate the improvements in parasympathetic nervous system activity, in addition to metabolic profile and cardiorespiratory fitness in overweight and obese adolescents.

Parent-proxy perception of overweight adolescents' health-related quality of life is different according to adolescent gender and age and parent gender.

UNLABELLED: This study assessed health-related quality of life (HRQoL) reported by overweight adolescents and compared to their parent-proxy perception of HRQoL, according to adolescent gender, adolescent age, and parent gender. Patients and a total of 179 adolescents aged 10 to 18 years with excess weight were evaluated for perceived HRQoL prior to beginning a weight-loss intervention, using the Pediatric Quality of Life Inventory (PedsQL 4.0) questionnaire, estimating quality of life in the physical, emotional, social, and school domains, as well as index measures of psychosocial and overall quality of life. Parents completed the same questionnaire estimating his or her child's HRQoL. Compared to their child's self-report, parents underestimated all the domains of HRQoL except the school domain. Parents underestimated all the domains of HRQoL among boys; however, they only underestimated the physical domain among girls. Comparisons between parent-proxy perception and self-report of the adolescent according to adolescent's age revealed that parents underestimated their children's HRQoL in the younger adolescents (10 to 13 years) for all except for the school domain and underestimated only the physical domain in older adolescents (14 to 18 years). The same comparison between parent-proxy perception and their child's self-report of HRQoL according to parent gender showed that mothers underestimated HRQoL in all domains except for the school domain, while fathers only underestimated the school domain. CONCLUSION: The differences between self-report of overweight adolescent and perceptions of their parents about the HRQoL of their children are influenced by adolescent gender and age and parent gender.

Tratamento multiprofissional da obesidade e sua cessação em adolescentes: efeitos no perfil hemodinâmico / Multiprofessional treatment of obesity and its cessation in adolescents: effects on hemodynamic profile

Avaliar os efeitos de um Programa Multiprofissional de Tratamento da Obesidade (PMTO) e de sua cessação sobre o perfil hemodinâmico de adolescentes. Foram avaliados 19 adolescentes com excesso de peso de 10 a 18 anos. Medidas antropométricas, pressão arterial e frequência cardíaca de repouso foram incluídas na análise. Os adolescentes completaram 16 semanas do PMTO com uma equipe multiprofissional focada em promover mudanças no estilo de vida dos adolescentes. Os mesmos retornaram para avaliação após oito semanas de cessação das atividades. Após o PMTO, foi observada redução na frequência cardíaca de repouso nas meninas sem diferença significativa para o momento de cessação. Os meninos apresentaram melhora para as variáveis: circunferência abdominal, IMC, gordura relativa e massa magra após o PMTO. Após o período cessação houve aumento significativo apenas no peso. Os resultados evidenciam o impacto positivo de um PMTO demonstrando efeitos diferentes de acordo com o gênero.

To evaluate the effects of a Multiprofessional Program of Obesity Treatment (PMTO) and its cessation on hemodynamic profile in adolescents. We evaluated 19 excess of weight adolescents aged from 10 to 18 years. Anthropometric measures, resting blood pressure and resting heart rate were included in analysis. Adolescents completed 16 weeks of PMTO with a multiprofessional team focused on promote lifestyle changes in adolescents. The same adolescents returned to evaluation after eight weeks of activities cessation. After PMTO, we observed reducing in heart rate of girls without differences to cessation moment. Boys presented improvement in variables: abdominal circumference, BMI, relative body fat and lean mass after PMTO. After cessation period there was significant increase on body weight. Results evidences the positive impact of PMTO demonstrating different effects according to gender.

Multidisciplinary therapy reduces risk factors for metabolic syndrome in obese adolescents.

This study aims to assess the effects of a 16-week multidisciplinary program of obesity treatment on the control of metabolic syndrome (MS) and dyslipidemia in obese adolescents. Eighty-six adolescents aged 10-18 years were allocated in either the intervention group (IG; n = 44) or control group (CG; n = 42). IG was submitted to a multidisciplinary intervention based on cognitive behavioral therapy that aimed to modify eating habits and exercise behavior. We analyzed, before and after the intervention period, anthropometric parameters, body composition, bone mineral density, cardiorespiratory fitness, blood pressure, glucose, insulin, and lipid profile of the subjects. MS was classified according to International Diabetes Federation (2007) and the presence of dyslipidemia according to Back et al. (Arq Bras Cardiol 85:4-36, 2005). In the beginning of the intervention, the median number (range) of risk factors for MS present was 2.0 (0.0-5.0) in the IG and 2.0 (0.0-4.0) in the CG. After the intervention, this parameter reduced significantly in the IG (1.0 (0.0-5.0); p = 0.004) while no change was observed in the CG (2.0 (0.0-4.0); p = 0.349). In addition, we observed improvements in body mass index, waist circumference, hip circumference, maximal oxygen uptake, absolute and relative body fat, systolic blood pressure, diastolic blood pressure, and total cholesterol in the IG which was not identified in the CG. Conclusio n: We suggest that a 16-week multidisciplinary intervention based on cognitive behavioral therapy was adequate to reduce risk factors for MS in obese adolescents.

Efeitos de um programa multiprofissional de tratamento da obesidade e de sua cessação sobre a aptidão física relacionada à saúde de adolescentes / Effects of a multiprofessional program for obesity treatment and its cessation on physical fitness related to health in adolescents

O objetivo do estudo foi avaliar os efeitos de um programa multiprofissional de tratamento da obesidade (PMTO) e de sua cessação sobre a aptidão física e composição corporal de adolescentes. Foi conduzido um estudo quase-experimental com 19 adolescentes com excesso de peso de ambos os gêneros e idade entre dez e 18 anos. Os mesmos foram submetidos a 16 semanas de intervenção com foco na mudança do comportamento alimentar e de atividade física. Na sequência, os adolescentes retornaram para avaliação após oito semanas de cessação das atividades. Foram observadas mudanças na aptidão cardiorrespiratória (26,39±6,18 mL/kg/min para 30,99±7,84 mL/kg/min) e gordura corporal (40,67±6,61% para 36,73±7,77%), com o PMTO, porém essas melhoras não se mantiveram após o período de cessação (27,56±7,31 mL/kg/min e 38,09±7,84%, respectivamente). Os resultados demonstraram que 16 semanas são suficientes para promover mudanças na aptidão física e composição corporal, entretanto, estas parecem não ser incorporadas no novo estilo de vida dos adolescentes.

The aim of the study was to evaluate the effects of a multiprofessional program for obesity treatment (PMTO) and its cessation on the physical fitness and body composition of adolescents. We conducted a quasi-experimental study with 19 overweight/obese adolescents of both gender and aged from 10 to 18 years. These adolescents participated of a 16-week intervention focused on the food change and exercise behavior. Subsequently, the adolescents returned for evaluation after eight weeks of cessation of the activities. We observed important changes related to the cardiorespiratory fitness (26.39±6.18ml/kg/min to 30.99±7.84ml/kg/min) and the body fat (40.67±6.61% to 36.73±7.77%), however, changes were not maintained after the cessation period (27.56±7.31ml/kg/min and 38.09±7.84%, respectively). The results showed that 16 weeks of PMTO were enough to improve the physical fitness and the body composition, but did not change the lifestyle of these adolescents in order to maintain the gains promoted by PMTO.

Ciclo rítmico metabólico, composição corporal e exercício físico / Metabolic rhythmic, body composition and exercise

A prevalência da obesidade vem aumentando em todo o mundo, parecendo não ser somente uma epidemia, mas uma representação fisiológica anormal, bem como uma resposta natural às práticas do mundo moderno. Neste contexto, o presente trabalho teve com objetivo organizar e verificar a aplicabilidade dos conteúdos dos ciclos metabólicos referente à composição corporal, sono e prática de exercícios físicos. Observa-se que tanto a qualidade do sono quanto a prática de exercícios físicos podem modular ciclos rítmicos metabólicos, verificou-se esse comportamento com vários estudos com diversos hormônios. Os resultados apontaram para a inclusão de parâmetros relacionados à qualidade de sono e da prática regular de exercícios físicos não só no tratamento da obesidade, mas também em casos de diabetes, síndrome metabólica entre outras doenças, pois estes demonstraram poder ter influência sobre o acúmulo de adiposidade corporal e na regulação circadiana.

The prevalence of obesity is increasing worldwide, seems not only an epidemic, but an abnormal physiological representation, and a natural response to the practices of the modern world. In this context, this study was aimed organize and verify the applicability of the contents of metabolic cycles on body composition, sleep and physical exercise. It is observed that the quality of sleep as the practice of physical exercise may modulate rhythmic metabolic cycles, there was this behavior in several studies with various hormones. Results pointed to the inclusion of parameters related to quality of sleep and regular practice of physical exercise not only in the treatment of obesity, but also in cases of diabetes, metabolic syndrome and other diseases, because they demonstrated to have influence on the accumulation of adiposity body and the circadian regulation.
