Definicja i opis
EN
If a dual-energy x-ray absorptiometry (DXA) examination is not feasible, the PhenX Anthropometrics Working Group (WG) noted that other body composition assessment methods may be considered. For example, bioelectrical impedance analysis (BIA) and skinfold thickness measures are potentially useful, albeit less precise and valid as indicators of body composition. Study-specific protocols and equipment descriptions should be reviewed carefully. In the National Health and Nutrition Examination Survey (NHANES) a certified radiologic technician positions the participant and operates the DXA scanner device. Due to concerns about radiation exposure to the unborn fetus, urine pregnancy tests or self-reported pregnancy history were used to exclude pregnant females from the NHANES DXA component. Equipment limitations excluded NHANES participants who weighed more than 300 lbs or were more than 6'5" tall. Individuals with amputations other than fingers and toes were also excluded from the NHANES DXA exam.The technician should determine if the participant is wearing metallic items such as jewelry or eyeglasses, had implanted medical devices such as a pacemaker or artificial joint, or had undergone certain types of medical tests that might affect the scan results. The NHANES DXA Procedures Manual describes the protocol, exclusions, and screening questions in detail. Rigorous quality control procedures are needed to monitor the performance of the DXA scanner, the performance of the certified radiology technologists who performed the DXA scan, and the quality of the DXA scans. The NHANES DXA Procedures Manual describes the quality assurance and quality control measures that were used in NHANES.
