Body weight as an indicator of fat-free mass in active elderly XXXX .

@entity1 @entity1386
OBJECTIVE: @entity1386 ( @entity1386 ) reduction and the tendency for a reduction in surrounding fatty issue and increase in the middle are a natural consequence of growing old and should be studied in order to gain a better understanding of the aging process. This study set out to find the @entity1386 differences between active elderly @entity1 in two age groups (60-69 and 70-80 years) and to determine which of the anthropometric measurements, body weight (BW), abdominal circumference (AC), or body mass index (BMI) are the best predictors of @entity1386 variation within the group. METHODS: Eighty-one (n=81) active elderly @entity1 of the Third Age willingly signed up to participate in the research during the activities at the University of the Third Age (UTA) in Brazil. The research was approved by the Research Ethics Committee of the Faculty of Medical Sciences of the State University of Campinas (UNICAMP). Body weight (BW), height (H) and the BMI were measured according to the international standards. The AC was measured in centimetres at the H of the navel and body composition was ascertained using bioimpedance analysis. The SAS program was used to perform the statistical analysis of independent samples and parametric data. RESULTS: The results showed @entity1386 values with significant differences between the two groups, with the lowest values occurring among the @entity1 who were over 70 years of age. In the analysis, the Pearson's Correlation Coefficient for each measured independent variable was ascertained, with the BW measurement showing the highest ratio (0.900). CONCLUSIONS: The BW measurement was regarded as reliable, low-cost and easy to use for monitoring @entity1386 in elderly @entity1 who engage in physical activities.
