Physical, clinical, and psychosocial parameters of adolescents with different degrees of excess weight

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 weightincreased (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.

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

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.
