Body composition validation technique using anthropometrics surrogates in recumbent patients with standing inability: A pilot study report
AbstractThe purpose of this study was to develop an alternative technique for the
determinationof body compositioninpeople or patientswho areunable to stand erect as a result ofdisease or injury. Itwas aprospectivepilot studyusing apparentlynormal subjects involving twenty-two (16males and 6females) volunteer subjects randomly recruited for the study. The means and standard deviations for their ages, body weights and heights were 31.20±7.47, 68.59±6.19 and 1.72±0.05 respectively. All the participants gave informed consent to participate in the study. The horizontal bodyweights of the participantsweremeasured inlying positionsusing anadaptation of theGuthri Smith apparatus frame towhich a firmstretcher and two spring balances were attached on a horizontal level position. The heights of the subjects were also taken on supine lying on a firm plinth. The body weight and height of each of the subjects were also measured in standing with the conventional weighing scale and a stadiometer. The body mass index (BMI) and waist-to-hip ratio (WHR) were calculated for all the subjects with values obtained in both positions. The OMRON body fat monitor was also used to assess the percentage fat per height (%F/Ht) and fat mass per weight (FMWt) of each of the subjects in standing and lying positions. The results of the study showed that there were no significant differences between the body weights, heights, BMI, WHR, %F/Ht, and FMWt measured at vertical standing and horizontal lying positions. However, there were significant differences in the waist and hip circumference measurements taken in the two positions. The results also showed positive correlation between body weight and height, and BMI, %F/Ht andWHR derived from anthropometric parameters taken from both positions.It was concluded that anthropometry in standing and supine lying are of clinical use and associated, and developing practical horizontal weighing system may serve great gains for use in peoplewith difficulties and or inabilities to stand, especially in young and middle-aged patients with spinal cord injuries during their acute and rehabilitative stages.
