ABSTRACT
BACKGROUND:
Ethnic differences in the association between body mass index (BMI) and body fat suggest that body composition varies across ethnic groups.OBJECTIVE:
To investigate the association between impedance index - a measure of tissue resistivity - and BMI in adults of different ethnic groups (Asian Indians, West Africans and White Caucasians) living in their native countries.METHODS:
Male (n=329) and female (n=277) adult subjects (18-50 years) living in urban areas in the UK, The Gambia and Pakistan were studied. Body weight and height were measured and BMI calculated. The same leg-to-leg bioimpedance instrument was used in each study and impedance index (height(2) (cm)/impedance (Omega)) used as measure of tissue resistivity.RESULTS:
In women, Asian Indians and West Africans had a significantly greater increase in impedance index per unit increase in BMI compared with white Caucasians (P<0.001). In men, Asian Indians had a significantly lower impedance index compared with West Africans and white Caucasians (P<0.001).CONCLUSION:
Different ethnic groups may have different tissue resistivity for the same BMI indicative of systematic differences in body composition.
