“…In a recent publication on the relationship between excess weight and risk for chronic renal failure showed that the risk of renal failure is three times higher for obese patients [29]. This finding supports the importance of the relationship of obesity to postoperative renal failure found in the sample studied.…”

O efeito do índice de massa corporal sobre as complicações no pós-operatório de cirurgia de revascularização do miocárdio em idososThe effect of the body mass index on postoperative complications of coronary artery bypass grafting in elderly Abstract Objectives: To evaluate the effect of BMI (body mass index) in the postoperative period of elderly patients undergoing CABG.Methods: Cross-sectional retrospective study, carried out in academic hospital, with all patients (n=290), aged or above 60 years, undergone CABG, from August 2006 to July 2007. The patients were divided into tertiles of BMI (<22, 22-27,> 27kg /m²). The variables included in the study were collected from medical records of patients and analyzed by logistic regression in association with the categories of BMI.Results: In the group with malnutrition were found larger percentage of impaired lung, kidney, hospital stay and immediate surgical mortality; but without statistical significance. Among female patients, the group malnutrition and eutrophy, 61.5% had hospital stay for a period longer than seven postoperative days compared to 42.5% male patients (p=0.003). In the group with malnutrition was found association between the CPB time and renal dysfunction with p<0.001 and, in eutrophic group with p=0.04. Obesity obtained protective association for lung dysfunction (RR=0.99), readmissions (RR=0.45) and mortality (RR = 0.77), and risk factor for renal dysfunction (RR=1.12).

“…BMI and body mass values increase with age, while stature and lean mass decrease. 1,11 However, our findings show that BMI maintained a similar correlation with measures of adiposity in all age groups, which indicates that the relationship between BMI and adiposity remains similar, regardless of ageing. On the other hand, the correlation with tricipital skinfold among men decreased markedly between the middle-aged (40-59.9 years) and elderly groups, and, consequently, so did the correlation with arm fat area.…”

“…1 Moreover, the centralization of body fat seems to be a better predictor for complications in this group. 14 Changes related to gains in visceral or subcutaneous fat associated with ageing may be affected by both the initial amount of fat and by increases in body mass.…”

“…1,3 Additionally, the use of the BMI in elderly persons is further complicated by the frequent presence of diseases and the lack of specific cutoff points for this age group. Thus, there has been an extensive discussion regarding the use of the BMI and the limits of normality to be adopted for studying overweight and obesity of this measure was determined by comparing it to the measure obtained using a Lange adipometer.…”

ObjectiveTo evaluate the nutritional status of elderly persons and to compare the correlation between the body mass index (BMI=kg/m 2 ) with measures of adiposity and fat distribution among elderly and middle-aged adults. Methods Elderly persons (N=699; 60 years or older) and middle-aged adults (N=1,306; 40-59.9 years) participating in a population-based survey conducted in 1996 in the municipality of Rio de Janeiro were evaluated as to body mass index, arm, waist, and hip circumferences, skinfolds, and arm fat and muscle areas using standardized procedures. The cutoff points proposed by the World Health Organization for waist circumference, waist-to-hip ratio, and body mass index were used. Analyses were performed using the Spearman correlation coefficient and linear regression adjusted for age. Results About 50% of elderly subjects were classified as overweight and more than 50% of women in all age groups had waist circumference and waist-to-hip ratio outside the normal range. Among men, these percentages were about 40% for waist circumference and 20% for waist-to-hip ratio. Among elderly subjects, the partial correlation (adjusted for age) between body mass index and measures of adiposity (waist circumference, skinfolds, and arm fat area) ranged from 0.45 to 0.85 for men and 0.55 to 0.86 for women. Weight and waist circumference were the variables more strongly correlated with body mass index among both elderly persons and adults. Conclusions The prevalence of overweight among elderly persons was high for both men and women. Body mass index shows a similar relationship with adiposity regardless of ageing.

Evaluation of air-displacement plethysmography and bioelectrical impedance analysis vs dual-energy X-ray absorptiometry for the assessment of fat-free mass in elderly subjects

Objective: To evaluate air-displacement plethysmography (ADP) and bioelectrical impedance analysis (BIA) vs dual-energy X-ray absorptiometry (DXA) for the assessment of fat-free mass (FFM) in healthy elderly subjects. Subjects: Forty-two women and twenty-six men aged 60-84 years. Methods: FFM was measured by DXA and ADP. Body impedance (Z) was measured by four-polar BIA and the impedance index (ZI) was calculated as stature 2 /Z. Selection of predictors (gender, age, weight and ZI at 5, 50 and 100 kHz) for BIA algorithms was carried out using bootstrapped stepwise linear regression on 1000 samples of 68 subjects. Limits of agreement were used as measures of interchangeability of ADP and BIA with DXA. Results: The limits of agreement of ADP vs DXA were À11.0 to 2.4 kg in males and À4.8 to 2.2 kg in females. Gender, weight and ZI 100 were selected as predictors of FFM by bootstrapped stepwise linear regression. In males, ZI 100 (À12.2 to 12.2 kg) was much less accurate than weight (À6.0 to 6.0 kg) at predicting FFM and their combination did not improve the estimate (À6.0 to 6.0 kg). In females, ZI 100 (À6.8 to 6.8 kg) was less accurate than weight (À5.6 to 5.6 kg) at predicting FFM and their combination improved the estimate only slightly (À5.0 to 5.0 kg). Conclusions: In healthy elderly subjects, (1) ADP and DXA are not interchangeable for the assessment of FFM, especially in males; and (2) ZI 100 is not superior to weight for the prediction of FFM and their combination is of little advantage and only in females.
