Dessa maneira, o objetivo do presente estudo foi comparar os componentes da composição corporal obtidos pelas mensurações realizadas com a bioimpedância elétrica (BIA), na posição horizontal (supina) ortostática (vertical). A amostra constitui-se de 270 sujeitos (66 masculino e 204 feminino), com idade compreendida entre 30 e 80 anos. Mensurou-se peso, estatura e registrou-se a reatância e resistência por meio da bioimpedância elétrica (BIA Analyzer-101Q, RJL Systems, Detroit, USA). Sendo o primeiro registro com o participante deitado em posição supina sobre colchonetes, em seguida, o segundo registro foi realizado com os participantes em pé.

Junto a estas modificações, a inatividade física passa ser considerada como um agravante no surgimento de doenças e no acúmulo de adiposidade corporal. O acúmulo de gordura pode ser determinante no rendimento motor. A partir disso, o objetivo do presente estudo foi observar a influência da adiposidade corporal na aptidão cardiorrespiratória em indivíduos idosos do sexo feminino. A amostra foi composta por 256 mulheres, participantes de programas de exercícios físicos, com idade entre 60,0 e 69,8 (64,3 ±2,84), residentes das cidades de Presidente Prudente-SP e Uberaba-MG-Brasil. Foram mensurados os valores de Índice de Massa Corporal (IMC), Razão Cintura e Quadril (RCQ), Índice de Conicidade (IC) e da Razão entre Cintura/Estatura (RCEst). A obtenção dos valores de Aptidão Cardiorrespiratória (AC) foi realizada por meio do Teste de Caminhada de Seis Minutos (TC6M). A análise estatística foi obtida após o agrupamento das variáveis a partir do percentil 50. A razão de chance foi obtida pelo testes exato de "Ficher", com o software R. A associação entre as variáveis foi calculada com o teste do Qui-quadrado, com Software SPSS 10.0. Todos os valores estatísticos foram estabelecidos com índice de significância de p=0,005. Foi observado que, o grupo de mulheres classificadas como baixo desempenho, apresentaram em média 2.0 vezes mais chances de possuir maiores valores de indicadores antropométricos. Desta forma, é possível concluir que a AC é negativamente influenciada pela adiposidade corporal.

Methods: This is an observational and analytical cross-sectional study conducted with a convenience sample of 367 elderly women (60 and over) from the cities of Presidente Prudente, SP and Uberaba, MG, between October/2010 and August/2012. NCDs were identified using a questionnaire based on the Standard Health Questionnaire (SHQ). The International Physical Activity Questionnaire (IPAQ) was used to assess the level of physical activity and anthropometric variables were used to assess the nutritional status. Statistical analysis included the chi-square test to verify associations between physical activity level, according to nutritional status, and the presence of cardiometabolic diseases, and binary logistic regression to test the magnitude of these associations. Results: There was a protective factor against hypertension in active eutrophic women (p=0.024) and sedentary eutrophic women (p=0.032) when compared to the risk group (sedentary and overweight/obese women); however, this was not observed in physically active women with excess weight (p=0.734). There was a positive association between sedentary eutrophic elderly women (p=0.047) and the risk of cholesterol. None of the groups were associated with diabetes. Conclusion: Physical activity was not considered a protective factor for hypercholesterolemia, diabetes or hypertension, possibly due to reverse causality given that sedentary women started the physical activity after the diagnosis of the disease, which contributed to these results.

The sample included 116 subjects aged 80 years and older. The body composition was measured using dual-energy X-ray absorptiometry (DXA) and mobility was assessed by motor tests. The χ2 test was used to analyze the proportion of older people with sarcopenia, obesity and sarcopenic obesity based on sex as well as to indicate an association between obesity, sarcopenia, sarcopenic obesity and mobility. Binary logistic regression, adjusted for the variables (sex and osteoarticular diseases), was used to express the magnitude of these associations. One-way analysis of variance was used to compare the mobility of four groups (Normal, Obesity, Sarcopenia and Sarcopenic Obesity). The Sarcopenia Group had lower performance in the lower limbs strength test and in sum of two tests compared with Obesity and Normal Groups. Older p...

Material and method: : The sample consisted of 113 older people aged !80 years. The assessment of body composition was made using Dual Energy X-ray Absorptiometry (DXA) and the lipid profile analysis using an enzymatic colorimetric kit. We used Analysis of Variance (ANOVA) test to compare the mean of lipid profile according to body composition and were constructed logistic regression models to verify the association between these two variables. Results: It was found that older people with high fat had higher mean values of TG compared to normal and low muscle mass group. Older people with low muscle mass showed mean values of LDL-c lower than other groups. It was observed that older people with high fat is more likely to have (OR 2.70; 95%CI 1.14-6.37) high blood concentration of TG. Conclusion: Thus, it appears that high fat is related to the high blood concentration of TG in older people aged !80 years, especially those with Asian origin and diabetes besides those with low muscle mass shows lower mean values of LDL-c.

Sample of 113 individuals aged 80 to 95 years (83.4 + 2.9 years), of both sexes, from Presidente Prudente, São Paulo state. Waist circumference (WC), body mass index, percentage of total body fat (% BF), hypertension, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides, and glucose were used for characterization of risk factors. The chi-square test was used to assess proportions of risk factors and Student’s t test to compare the results between the sexes. High prevalence of risk factor was observed, mainly hypertension (67.3%) and % BF (79.6%). Male participants presented higher weight, height, and WC ( p < .001), and female participants, higher TC and % BF ( p < .001).

Despite these trends, our understanding of child obesity in Brazil is limited. Thus, the aims of this study were (1) to investigate the current prevalence of overweight and obesity in a large sample of children and adolescents living in São Paulo, Brazil, and (2) to identify the lifestyle behaviors associated with an increased risk of obesity in young Brazilians. Methods: A total of 3,397 children and adolescents (1,596 male) aged 7-18 years were randomly selected from 22 schools in São Paulo, Brazil. Participants were classified as normal weight, overweight, or obese based on international age-and sex-specific body mass index thresholds. Selected sociodemographic, physical activity, and nutrition behaviors were assessed via questionnaire. Results: Overall, 19.4% of boys and 16.1% of girls were overweight while 8.9% and 4.3% were obese. Two-way analysis of variance revealed that the prevalence of overweight and obesity was significantly higher in boys and in younger children when compared to girls and older children, respectively (P < 0.05 for both). Logistic regression analysis revealed that overweight was associated with more computer usage, parental encouragement to be active, and light soft drink consumption after controlling for differences in sex, age, and parental education (P < 0.05 for all). Conversely, overweight was associated with less active transport to school, eating before sleep, and consumption of breakfast, full-sugar soft drinks, fried food and confectionery (P < 0.05 for all). Conclusions: Our results show that obesity in São Paulo children and adolescents has reached a level equivalent to that seen in many developed countries. We have also identified three key modifiable factors related to obesity that may be appropriate targets for future intervention in Brazilian youth: transport mode to school, computer usage, and breakfast consumption.

Sample of 113 individuals aged 80 to 95 years (83.4 + 2.9 years), of both sexes, from Presidente Prudente, São Paulo state. Waist circumference (WC), body mass index, percentage of total body fat (% BF), hypertension, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides, and glucose were used for characterization of risk factors. The chi-square test was used to assess proportions of risk factors and Student’s t test to compare the results between the sexes. High prevalence of risk factor was observed, mainly hypertension (67.3%) and % BF (79.6%). Male participants presented higher weight, height, and WC ( p < .001), and female participants, higher TC and % BF ( p < .001). Only 7.1% of male and 4.2% of female participants showed no risk factors, and 71.3% of male and 85.9% of female participants had three or more...

Despite these trends, our understanding of child obesity in Brazil is limited. Thus, the aims of this study were (1) to investigate the current prevalence of overweight and obesity in a large sample of children and adolescents living in São Paulo, Brazil, and (2) to identify the lifestyle behaviors associated with an increased risk of obesity in young Brazilians. Methods: A total of 3,397 children and adolescents (1,596 male) aged 7-18 years were randomly selected from 22 schools in São Paulo, Brazil. Participants were classified as normal weight, overweight, or obese based on international age-and sex-specific body mass index thresholds. Selected sociodemographic, physical activity, and nutrition behaviors were assessed via questionnaire. Results: Overall, 19.4% of boys and 16.1% of girls were overweight while 8.9% and 4.3% were obese. Two-way analysis of variance revealed that the prevalence of overweight and obesity was significantly higher in boys and in younger children when compared to girls and older children, respectively (P < 0.05 for both). Logistic regression analysis revealed that overweight was associated with more computer usage, parental encouragement to be active, and light soft drink consumption after controlling for differences in sex, age, and parental education (P < 0.05 for all). Conversely, overweight was associated with less active transport to school, eating before sleep, and consumption of breakfast, full-sugar soft drinks, fried food and confectionery (P < 0.05 for all). Conclusions: Our results show that obesity in São Paulo children and adolescents has reached a level equivalent to that seen in many developed countries. We have also identified three key modifiable factors related to obesity that may be appropriate targets for future intervention in Brazilian youth: transport mode to school, computer usage, and breakfast consumption.
