ABSTRACT
O objetivo deste estudo transversal foi investigar a prevalência de sobrepeso e adiposidade central (AC) e suas relações com alterações no metabolismo de lipídeos, glicose e níveis pressóricos em uma amostra de 287 indivíduos adultos residentes em uma comunidade rural do Estado de Minas Gerais. Foram realizadas comparações de médias dos indicadores metabólicos: lipoproteínas, glicose e níveis pressóricos, segundo categorias de sobrepeso e AC, usando análise de variância e teste de Tukey. A prevalência de sobrepeso foi de 24,8 por cento (37,4 por cento no sexo feminino; 11,5 por cento no sexo masculino). A AC esteve presente em 28,1 por cento das pessoas (50,3 por cento no sexo feminino; 4,3 por cento no sexo masculino). Indivíduos com AC apresentaram maiores valores médios de pressão arterial (HA), colesterol total, LDL, triglicérides e glicemia de jejum; e menores valores médios de HDL. Foram verificadas associações entre AC e HA, dislipidemia e hiperglicemia. Associações significativas entre sobrepeso e HA, dislipidemia e hiperglicemia também foram evidenciadas. Esses resultados confirmam o potencial efeito das alterações na composição corporal, principalmente em nível central, sobre o metabolismo lipídico e de glicose, e também sobre o aumento dos níveis pressóricos em populações da área rural.
The aim of this cross-sectional study was to verify the prevalence of overweight and central adiposity (CA) in a sample of 287 adult subjects that lived in a rural community of Minas Gerais State. Means lipids, lipoproteins, glucose and blood pressure levels were compared according adiposity categories using One-way ANOVA and Tukey tests. Prevalence of overweight was 24.8 percent (37.4 percent for female; 11.5 percent for male). CA was verified in 28.1 percent of the individuals (50.3 percent for female; 4.3 percent for male). The associations between CA and overweight with the metabolic disorders: arterial hypertension (AH), dyslipidemia and hyperglycemia were estimated. Subjects with CA presented higher mean values of blood pressure, total cholesterol, LDL, triglycerides, fasting glucose, and lower mean values of HDL. CA was associated with AH, dyslipidemia and hyperglycemia. Associations between overweight and AH, dyslipidemia and hyperglycemia were also verified. These results confirm the potential effect of body composition shifting, especially at the abdominal level, on lipids, glucose metabolism and on blood pressure levels in rural populations.

The authors present the results obtained with the development of an experimental model of bronchial fistula and compared different forms of post-pneumonectomy bronchial fistula protection. Forty rats were submitted to left pneumonectomy and bronchial stumps were protected with either pedicled muscle ( N=20 ) or pedicled fat ( N=20 ). The results showed that it was possible to develop a fistula model in 65 por cento of animals and that there was no statistical difference ( p>0.05 ) between the tissues used for bronchial protection
