Resting energy expenditure in obese women: comparison between measured and estimated values.

Assessing energy requirements is a fundamental activity in clinical dietetic practice. The aim of this study was to investigate which resting energy expenditure (REE) predictive equations are the best alternatives to indirect calorimetry before and after an interdisciplinary therapy in Brazilian obese women. In all, twelve equations based on weight, height, sex, age, fat-free mass and fat mass were tested. REE was measured by indirect calorimetry. The interdisciplinary therapy consisted of nutritional, physical exercise, psychological and physiotherapy support during the course of 1 year. The average differences between measured and predicted REE, as well as the accuracy at the ±10 % level, were evaluated. Statistical analysis included paired t tests, intraclass correlation coefficients and Bland-Altman plots. Validation was based on forty obese women (BMI 30-39·9 kg/m2). Our major findings demonstrated a wide variation in the accuracy of REE predictive equations before and after weight loss in non-morbid, obese women. The equations reported by Harris-Benedict and FAO/WHO/United Nations University (UNU) were the only ones that did not show significant differences compared with indirect calorimetry and presented a bias <5 %. The Harris-Benedict equation provided 40 and 47·5 % accurate predictions before and after therapy, respectively. The FAO equation provided 35 and 47·5 % accurate predictions. However, the Bland-Altman analysis did not show good agreement between these equations and indirect calorimetry. Therefore, the Harris-Benedict and FAO/WHO/UNU equations should be used with caution for obese women. The need to critically re-assess REE data and generate regional and more homogeneous REE databases for the target population is reinforced.

Long-term interdisciplinary therapy decreases symptoms of binge eating disorder and prevalence of metabolic syndrome in adults with obesity.

Obesity-associated comorbidities greatly impact the quality and expectancy of life. Binge eating disorder (BED) is the most prevalent eating disorder and it is an important risk factor for obesity and metabolic syndrome (MetS). For these reasons, we aimed to assess the effect of an interdisciplinary therapy on the symptoms of BED and the prevalence of MetS in obese adults. It was hypothesized that the interdisciplinary therapy would decrease symptoms of BED and markers of MetS. Twenty-four volunteers (BMI 34.80±3.17 kg/m2; 41.21±6.28 years old) completed a 32-week intervention. Biochemical characteristics, body composition, the degree of symptoms of binge eating, and macronutrients, and sodium consumption pre- and post-treatment were determined. The prevalence of MetS dropped from 75% to 45.8%, post-therapy. Among the markers of MetS, waist circumference and systolic blood pressure decreased significantly, whereas high-density lipoprotein levels increased. Fasting plasma glucose, diastolic blood pressure, and triglycerides did not change. Based on binge-eating scale (BES) scores, before therapy, 33.3% of volunteers were classified as moderate bingers, and after therapy all volunteers were classified as having no BED symptoms. No difference in the prevalence of MetS between individuals classified as normal or moderate bingers was observed, but we found a positive post-therapy correlation between the BES score and body fat, gynoid fat and trunk fat. Sodium, fat, and carbohydrate consumption decreased. Protein intake did not change. In conclusion, the interdisciplinary approach was efficient in reducing symptoms of BED and MetS prevalence in this population.

The excessive caloric intake and micronutrient deficiencies related to obesity after a long-term interdisciplinary therapy.

OBJECTIVE: The aim of this study was to assess the effectiveness of a long-term interdisciplinary lifestyle modification therapy on food intake, body composition, and anthropometric measurements of obese women. METHODS: Seventy obese women (age 41 ± 5.9 y) attended the interdisciplinary therapy, with nutrition, physical exercise, physiotherapy, and psychological support during the course of 1 y. Usual food intake was estimated by 3-d dietary record. Dual-energy x-ray absorptiometry was performed to determine body fat and fat-free mass. Waist and hip circumferences also were measured. Student's t test and Wilcoxon test were used for comparisons among categories; P < 0.05 was considered significant. RESULTS: The assessment of dietary intake showed significant changes after interdisciplinary therapy. A reduction in intake of total calories (18.3%), carbohydrates (15.6%), and total fats (13.1%) was observed. Total micronutrient intake did not change positively after therapy, as the intake level of 16 micronutrients was still lower than recommended. The therapy was effective in reducing significantly body weight (5.9%), body mass index (6.1%), body fat (4.7%), and waist (5.2%) and hip (3.8%) circumferences. CONCLUSIONS: Long-term interdisciplinary therapy was effective in decreasing the intake of calories, carbohydrates, and fats. The therapy positively changed the body composition and reduced anthropometric measurements. However, the intake of some micronutrients after therapy was still significantly lower than recommended. These results demonstrated that the proposed interdisciplinary methodology can be effective in treating obesity; however, the present study reinforced the need to address the micronutrient deficiency in the target population.

Static, dynamic balance and functional performance in subjects with and without plantar fasciitis / Equilíbrio estático, dinâmico e desempenho funcional em indivíduos com e sem fasciíte plantar

Abstract Introduction: Plantar fasciitis (PF) is characterized by non-inflammatory degeneration and pain under the heel, and is one of the most common foot complaints. The compensations and adjustments made to decrease the discomfort caused by the disease are clinical findings and can be a factor that contributes to impaired balance and decreased functional performance. Objective: To compare functional performance as well as static and dynamic balance among subjects with and without PF. Methods: The sample consisted of 124 subjects of both sexes aged 20-60 years. Participants were divided into two groups: a bilateral PF group (PFG; n = 62) and a control group (CG, n = 62). The following outcomes were analyzed: static and dynamic balance (using functional tests) and functional performance (using a questionnaire). We used Student's t test for independent samples to compare variables between the groups. The alpha error was set at 0.05. Results: Subjects with PF showed greater impairment in their overall dynamic balance performance (p < 0.001) than the control group, except for left posteromedial movement (p = 0.19). The CG showed showed better functional performance (p < 0.001) than the PF group. There was no difference between groups for the variable static balance on stable (p = 0.160) and unstable surfaces (p = 0.085). Conclusion: Subjects with PF displayed smaller reach distances in the overall Star Excursion Balance Test (SEBT), demonstrating a deficit in dynamic balance and functional performance when compared with healthy subjects.

Resumo Introdução: A fasciíte plantar (FP) caracteriza-se por uma degeneração não inflamatória e dor na parte inferior do calcanhar, sendo uma das queixas mais comuns na região do pé. As compensações e as adaptações para diminuir o desconforto da doença é um achado clínico e atua como um fator que pode contribuir para o comprometimento no equilíbrio e no desempenho funcional. Objetivo: comparar os equilíbrios estático, dinâmico e o desempenho funcional entre indivíduos com e sem a FP. Métodos: participaram da pesquisa 124 voluntários distribuídos em dois grupos: grupo fasciíte plantar bilateral (GFP; n = 62) e grupo controle (GC; n = 62) de ambos os sexos, na faixa etária de 20 a 60 anos. Os desfechos analisados foram o equilíbrio estático, equilíbrio dinâmico por meio dos testes funcionais e o desempenho funcional por um questionário. Os resultados foram analisados utilizando o teste t de Student de amostras independentes para comparar as variáveis entre os grupos. O erro alfa considerado foi p < 0,05. Resultados: Indivíduos com FP apresentaram maior comprometimento durante o teste de equilíbrio dinâmico total (p < 0,001), exceto no movimento póstero-medial esquerdo (p = 0,19). O GC apresentou melhor desempenho funcional (p < 0,001) e não houve diferença entre os grupos para a variável equilíbrio estático nas superfícies estável (p = 0,160) e instável (p = 0,085). Conclusão: Indivíduos com FP obtiveram menores alcances no SEBT total, apresentando déficit de equilíbrio dinâmico e comprometimento no desempenho funcional quando comparados com os participantes saudáveis.
