Abstract: the purpose of this research was to describe the overweight prevalence and factors potentially associated to it in adults residents in areas of social exclusion. the sample consisted of 3,214 individuals, aged 20 to 69 years, in shanty town in maceió-al, northeast of brazil. body mass index (bmi) was used in the nutritional evaluation. overweight prevalence of 41.2% was found (46,2% females vs. 32,6% males, p<0.001). the analysis indicated there is higher chance of getting overweight, both for males and females, in higher age ranges (prevalence ratio [rp]= 1.62, ci95% 1.37-1.90 and rp= 1.55, ci95% 1.41-1.69, respectively), and among those from rural areas (rp= 1.27, ci95% 1.07-1.51 and rp=2.23, ci95% 2.01-2.47, respectively). in males, the overweight risk is directly associated to the schooling level (rp=0.78, ci95% 0.63-0.97), whereas, in females it is inversely associated (rp=1.40, ci95% 1.17-1.66). a higher overweight risk was evidenced among men of higher income (rp= 1.29, ci95% 1.09-1.53). in general, small improvements in variables related to housing conditions and consumption goods are associated to higher overweight risk. even in populations of low socioeconomic level, improvement in housing conditions can become an overweight risk factor in adults for both genders, whereas education is a protective factor for women and the income a risk factor in men.

Abstract: O objetivo deste trabalho foi avaliar o estado nutricional e o consumo de nutrientes de hipertensos, na faixa etária de 18 a 74 anos, atendidos ambulatorialmente no Hospital das Clínicas da Universidade Federal de Pernambuco. A amostra, escolhida ao acaso, foi composta por 156 indivíduos de ambos os sexos (51 homens e 105 mulheres). As análises mostraram uma elevada prevalência de pacientes (73,1%) com peso acima da média e entre eles a hipertens o se associou significativamente com a obesidade (índice de Massa Corporal > 30 Kg/m2) e com o sobrepeso (índice de Massa Corporal >25 e < 30 Kg/m2) mas n o com a distribui o central de gordura. Em rela o ao consumo de nutrientes, os achados desta pesquisa revelaram um baixo consumo energético, o qual n o pode explicar a alta prevalência de sobrepeso e obesidade. De uma forma geral, exceto pelo cálcio, a ingest o média diária de nutrientes esteve adequada. No entanto, o consumo diário de sódio foi alto, 270 e 260 mEq para homens e mulheres, respectivamente.

Abstract: The currently available methods for evaluation of visceral obesity have limitations, making them impractical for evaluating large numbers of individuals. This study aimed to develop and validate prediction equations to estimate the area of visceral adipose tissue in young women. The sample included 64 women aged 19 to 36 years. The following variables were evaluated: visceral fat volume (VFV) measured by ultrasound; body mass index (BMI); waist circumference; waist-to-height ratio (WHtR); waist-to-hip ratio (WHR); conicity index; lipid profile; and fasting plasma glucose (FPG). The women were divided into two groups for development (n=48) and validation (n=16) of equations. Three equations were proposed and validated to estimate VFV: Equation 1: VFV = - 31.888 + (4.044 x BMI); Equation 2: VFV = - 51.891 + (248.018 * WHtR); and Equation 3: VFV = - 130.941 + (198.673 x WHtR) + (1.185 x FPG); with a predictive power of 34%, 24%, and 45% respectively. There was no statistically significant difference between VFV values assessed by ultrasound and estimated by the prediction equations in the validation group. The proposed equations can be used to calculate VFV in young women when imaging tests are not available, providing a valuable tool for epidemiological studies and health services.
