Brief summary
This study aims to evaluate some quick, portable methods, which when combined would provide accurate body composition measurement where current gold-standard methodologies are inaccessible. The results of this study will be of importance to a number of different areas relevant to the New Zealand population and will help us better design studies assessing body composition in the future.
Interventions
In a multi-ethnic group of young adults of varying body size, we will compare body composition measurements made using state-of-the-art 3-dimensional photonic body surface scanning (approx. 5 minutes duration) coupled with bioimpedance spectrometry (approx. 15 minutes duration) and skin-fold measurements (approx. 15 minutes duration). These results will be compared to those obtained by the dual x-ray absorptiometry reference technique (15- 20 minutes duration). This evaluation will be conducted in both men and women, and in people of different body sizes (i.e., normal-weight, overweight and obese) as part of one study visit (approx. 1 hour). This study will be conducted by researchers from the Human Nutrition and Body Composition Units at the University of Auckland in cooperation with researchers from the Defence Technology Agency of the New Zealand Defence Force.

Eligibility
Inclusion criteria
>Body Mass Indes (BMI) between 18.5 and 40 kg/m2 >Willing to comply with the scanning clothing requirements during the 3D photonic scanning i,e, wearing form-fitting clothes e.g. swimsuit, crop top and bike shorts, or close fitting underwear. This is to ensure accuracy of the measurement.
Exclusion criteria
>Pregnancy >Any form of implant (e.g. implanted cardioverter-defibrillator (ICD), prostheses or metal implants, a pace-maker, cochlear implant) >Amputees >Disorder of fluid balance (e.g. oedema, dehydration) >Any other condition associated with abnormal fluid status (e.g. kidney disease, organ failure, uncontrolled diabetes, malabsorptive syndromes, inflammatory bowel disease, use of diuretic medications or corticosteroids)
