Body mass index (BMI, kg/m 2) was calculated from weight and height, waist circumference was measured, and body fat (% fat) was determined from dual-energy X-ray absorptiometry (DXA) (Lunar).
Líkamssamsetningu var lýst með mælingum á hæð, þyngd og mittismáli og líkamsþyngdarstuðullinn (BMI = kg/m 2) var fundinn, hlutfall líkamsfitu var mælt með tvíorku röntgengeislagleypnimælingu [e. dual-energy X-ray absorptiometry (DXA)] með Lunar beinþéttnimæli.
