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 (TFM), android fat (AF) and gynoid fat (GF) mass in a selected group of healthy adult women with normal body mass index (BMI) in order to evaluate variations in fat distribution. Seventy seven women (20-69 years of age) with BMI values between ¡Ý 18.5 and ¡Ü 24.9 Kg/m2 were included. TMF, AF, GF and the AF to GF ratio (A:G) were assessed using DXA. Results showed an increase in AF after the 5th decade of life, which reached statistical significance in the 6th and 7th decades (p<0.05-0.008), a 33% increase in kg of AF between the 4th and 7th and a 20% increase in A:G ratio between the 3rd and the 7th, 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 5th decade of life.
