Fat Patterning Estimation of Persons With Spinal Cord Injury Using the Skinfold Technique

Jefferey A. Goodman, Davis and Elkins College, Elkins, WV

There are currently over 200,000 individuals with spinal cord injury (SCI) in the United States, and approximately 14,000 new SCI occur each year. As with the overall population, cardiovascular disease (CVD) is the leading cause of death among individuals with SCI. Epidemiological research has shown obesity to be a major risk factor for developing CVD. Obesity is prevalent in both sedentary and physically active people with SCI. Moreover, clinical concerns about the effects of obesity have been shifting from total body fat to that of fat patterning (Fp) and distribution, and indicate that the ability to estimate intra-abdominal fat is of primary importance as it relates to health. Dual energy x-ray absorptiometry (DXA) was used as the criterion measure. In this study, 57 white (n=41) and Hispanic (n=16) males with SCI, who ranged from 18 to 73 years of age (M=41.7 ± 14.07), were assessed using DXA and SF measures. Eleven standardized SF sites were measured and analyzed with partial correlations in varying combinations and ratios to determine the best predictors to enter, along with demographic information, as possible predictors for regression analysis. An equation was developed and validated to determine relative trunk fat (%TrF). %TrF=8.220 + (Chin + Chest + Calf + Subscapula) * .197 (R2=.62, SEE=5.48). A valid clinical method of determining Fp will enable health professionals to identify clients with SCI who are at-risk for disease and document BC changes due to exercise, Fp measures can also be used by medical and health professionals to monitor changes in fat and lean body mass resulting from SCI. This could lead to the development of more effective nutrition and exercise intervention strategies to counteract the increase of fat mass associated with SCI.
