title: Increase in android fat mass with age in healthy women with normal body mass index.
abstract: Body fat distribution is gender specific: men tend to accumulate adipose tissue in the android region, whereas women tend to do so in the gynoid region. The aim of the study was to assess total fat mass (TFM), android fat (AF), and gynoid fat (GF) mass in a selected group of healthy adult women with normal body mass index (BMI) to evaluate variations in fat distribution. Seventy-seven women (20--69yr of age) with BMI values between ≥18.5 and ≤24.9kg/m(2) were included. TMF, AF, GF, and the AF to GF ratio (A:G) were assessed using dual-energy X-ray absorptiometry. Results showed an increase in AF after the fifth decade of life (D), which reached statistical significance in the sixth and seventh decades (p<0.05--0.008), a 33% increase in kg of AF between the fourth and seventh and a 20% increase in A:G between the third and the seventh, with no significant changes in TFM and GF. In normal BMI women, age appears to be associated with changes in fat mass distribution with an increase in AF, which might have potential deleterious health consequences, after the fifth D.
