Abstract: The relationship between physical activity and the use of medicines is not clear. The purpose of this study was to investigate this relationship between the level of physical activity and the use of medications by type 2 diabetic patients who were attended in the Brazilian public healthcare system. The sample was composed of 121 Brazilian diabetic patients, of both genders, attended by the public healthcare system. Body fat (estimated by anthropometry and bioelectrical impedance), physical activity (measured by Baecke’s questionnaire), and the participant’s use of medicines (during the 15 days before evaluation) were assessed. There was a relationship between the use of medicines and: gender (r = 0.18; p = 0.045), body mass index (BMI) (r = 0.22; p = 0.012), waist circumference (r = 0.19; p = 0.029), body fat percentage (r = 0.21; p = 0.016), age (r = 0.23; p = 0.009), and level of physical activity (r = -0.22; p = 0.012). Linear regression included in the multivariate model only age (β = 0.718; p = 0.057), BMI (β= 0.057; p = 0.022), and level of physical activity (β = -0.176; p = 0.044). In conclusion, physical activity decreases medicinal use independent of age or obesity.

Abstract: The purpose of this study was to analyze the relationship between different body fat indicators, habitual physical activity and exposure to sedentary behavior in pre-adolescent males. The sample involved 60 subjects from 10 to 14 years old. The used body fat indicators were: the Body Mass Index, waist circumference, the sum of eight skinfolds, and estimation of percent of body fat using bioelectric impedance. The indicators of physical activity and sedentary behavior were assessed through a questionnaire. Descriptive statistical procedures were: mean, medium, standard deviations, minimum and maximum values, as well as the Spearman correlation. The SPSS software was used and P values lower than 5% were considered statistically signifi cant. None of the body fat indicators presented signifi cant correlation (p> 0.05) with indicators of habitual physical activity, although, all of them were moderately associated with time spent in sedentary activities (Body Mass Index: r= 0.42, waist circumference: r= 0.43, sum of skinfolds: r= 0.43 and percent of body fat: r= 0.43). Therefore, it is concluded that exposure to sedentary behavior correlates with body composition in pre-adolescent males aged 10 to 14 years. RESUMOO objetivo deste estudo foi analisar a rela o entre diferentes indicadores de adiposidade corporal, atividade física habitual e exposi o a comportamentos sedentários em jovens do sexo masculino. A amostra foi composta por 60 indivíduos com idade compreendida entre 10 e 14 anos. Foram utilizados como indicadores de adiposidade corporal: o índice de Massa Corporal, circunferência de cintura, somatória de oito dobras cutaneas e estimativas do percentual de gordura corporal, calculada por meio de impedancia bioelétrica. Os indicadores de prática de atividade física e comportamentos sedentários foram avaliados através da aplica o de questionário. Os procedimentos estatísticos adotados foram: valores de média, mediana, desvio padr o, valores mínimos, máximos e correla o de Spearman. O software utilizado foi o SPSS e valores de P inferiores a 5% foram considerados estatisticamente signifi cantes. Nenhum dos indicadores de adiposidade corporal apresentou correla o signifi cante (p> 0,05) com os indicadores de prática de atividade física, no entanto, todos foram moderadamente associados (índice de Massa Corporal: r= 0,42; circunferência de cintura: r= 0,43; somatória de dobras cutaneas: r= 0,43 e gordura percentual corporal: r= 0,43) com o tempo despendido em atividades sedentárias. Desta forma, conclui-se que a exposi o a comportamentos sedentários ap

Abstract: The sample was of 67 PLWHA(39 male and 28 female), aged 43.6+7.9 years. Body mass index, conicity index, waist/hip ratio, waist/height ratio and waist/thigh were calculated. Separated by sex, each index/ratio was plotted in a scatter chart with linear regression fit and their respective Pearson correlation coefficients. Analyses were performed using Prism statistical program and significance was set at 5%.The waist/height ratio presented the highest correlation coefficient, for both male (r=0.80, p<0.001) and female (r=0.87, p <001), while the lowest were in the waist/thigh also for both: male group (r=0.58, p<0.001) and female group (r=0.03, p=0.86). The other indices also showed significant positive correlation with DEXA.Anthropometric indices, especially waist/height ratio may be a good alternative way to be used for evaluating the distribution of fat in the abdominal region of adults living with HIV/ADIS.With the onset of the treatment with antiretroviral therapy (HAART) in the 90s, there was a significant increase in survival and quality of life of people living with HIV/AIDS (PLWHA), due to the action of this therapy in the fight against infectious and opportunist diseases [1]. However, pharmacological control of the disease has the side effect of altering body fat distribution, characterized by morphological changes (lipodystrophy) that result in excess fat in the central region of the body that increases the risk of cardiovascular diseases [2]. Despite some patients without HAART treatment present lypodistrophy, most of studies indicate that lypodistrophy in those under HAART, are time-dependent [3,4].Methods of analysis of body composition such as Dual Energy X-Ray Absorptiometry (DEXA) and Computed Tomography are considered the accurate techniques for body composition assessment for PLWHA [5,6]. However, the acquisition of sophisticated equipments or even the individual cost of each exam has made it difficult the access to most population [7].Given the dif

Abstract: The purpose of this study was to analyze the relationship between bioelectric impedance and adiposity and elevated cardiovascular risk indicators, and its effectiveness for detecting appropriate nutritional status, according to the Body Mass Index. A Cross-sectional study. The sample included 900 subjects, both males and females, with ages ranging from 11 to 17 years. Nutritional status was determined according to both Body Mass Index and relative body fat, estimated by bioelectric impedance. For both sexes, bioelectric impedance was signifi cantly correlated (p< 0.05) with all adiposity and cardiovascular risk indicators. Furthermore, it exhibited high specifi city for indicating nutritional status. It can be concluded that bioelectric impedance is a useful tool for body composition assessment. It can also be concluded that in young populations, care musty be taken when choosing equations to estimate relative body fat. Resumo O objetivo do presente estudo foi analisar a rela o da impedancia bioelétrica com indicadores de adiposidade e de elevado risco cardiovascular, e a efi ciência da mesma na indica o do estado nutricional, segundo o índice de Massa Corporal. Estudo de delineamento transversal. A amostra foi composta por 900 sujeitos de ambos os sexos e idade compreendida entre 11 e 17 anos. Foram coletadas informa es referentes ao peso corporal, estatura, prega cutanea tricipital, circunferência de cintura e valores de resistência e reatancia. A indica o do estado nutricional foi feita segundo valores de índice de Massa Corporal e gordura corporal relativa (impedancia bioelétrica). Para ambos os sexos, a impedancia bioelétrica correlacionou-se de forma signifi cativa (p< 0,05) com todos os indicadores de adiposidade e risco cardiovascular, além disso, apresentou alta especifi cidade na indica o do estado nutricional. Conclui-se que em popula es jovens, a utiliza o da impedancia bioelétrica é uma medida útil de avalia o da composi o corporal, no entanto, é necessária cautela na escolha da equa o mais adequada para se estimar a gordura corporal relativa.
