  1. Fulltext. Sex-specific associations of magnetic resonance imaging-derived intra-abdominal and subcutaneous fat areas with conventional anthropometric indices : The atherosclerosis risk in communities study.

    Article - En anglais


    Accurate measurement of central fat patterning is difficult to obtain by conventional anthropometry.

    Direct measurement of intra-abdominal fat area by magnetic resonance imaging, while accurate, is impractical for large-scale observational studies.

    This report examines the sex-specific associations of conventional anthropometric indices with intra-abdominal fat and subcutaneous fat areas measured by magnetic resonance imaging.

    A total of 157 volunteers (97 men and 60 women) aged 48-68 years of predominately white ethnicity had intra-abdominal fat and subcutaneous fat areas measured as part of the Atherosclerosis Risk in Communities (ARIC) Study.

    Weight, body mass index, waist circumference, waist : hip ratio, and subscapular skinfold thickness were measured or calculated by a standardized protocol.

    On average, women had a lower intra-abdominal fat area than men (109.5 cm2 vs. 152.9 cm2) but a higher mean subcutaneous fat area (287.8 cm2 vs. 214.6 cm2).

    After adjustment for age, intra-abdominal fat area was quadratically associated with body mass index, waist circumference, weight, and subscapular skinfold thickness in men ; in women, these associations were best modeled by a positive linear equation.

    Waist : hip ratio was linearly related to intra-abdominal fat area in both sexes.

    In general, anthropometric measures predicted lower percentages of the total variance in intra-abdominal fat area for men than for women. (...)
