Abstract:
Changes in body composition occur with age, particulariy loss of lean muscle mass, which may be a significant contributor to frailty and functional disability in the elderly. A variety of methods are currently available for directly or indirectly determining body composition. Densitometry, or underwater weighing of subjects, is the current gold standard for direct measurements. In frail elderly subjects, densitometry is not a pragmatic alternative for determining body composition. Traditional anthropometric measurements, and increasingly bioelectrical impedance analysis, are methods being used for indirectly determining body composition in elderly populations. The pilot study was designed to identify the relationship between anthropometry and bioelectrical impedance analysis for the measurement of body composition. The specific aims of the pilot study were to: 1) Compare two assessment measurements of body composition, anthropometric measurements and bioelectrical impedance analysis, in rural frail elders, and 2) To determine the correlation and consistency in predicting body composition within subjects in repeated measures over time. The long-term goals of the study include a better understanding of the relationship between anthropometric measurements and bioelectrical impedance analysis as estimates for fluid and nutritional status in elderly individuals. Eleven rural frail elders were recruited into the pilot study. Data collection methods included the following: structured interview guide, physiologic data, anthropometric skinfolds, circumferences and bioelectrical impedance analysis. All measurements were taken biweekly and measured twice for accuracy over an eight week period. The same two individuals measured all anthropometric skinfolds and circumferences during the study to increase measurement reliability. Preliminary data analysis has been conducted using descriptive statistic's, Pearson's correlation's and multiple linear regression techniques. The data initially suggests that anthropometric skinfolds are highly predictive of BMI whereas, bioelectrical impedance analysis may over predict or under predict selected body composition components in this population depending on individual characteristics of the subject.
