Adipose tissue attenuation as a marker of adipose tissue quality: Associations with six-year changes in body weight.

ABSTRACT:

Objective

Weight gain is associated with fat volume increases, but associations with fat quality are less well characterized The associations of weight change with visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volume and attenuation were investigated.

Methods

Computed tomography abdominal scans were acquired on a Framingham Heart Study subset (N = 836; 40.2% women; mean age 45.7 years), a mean of 6.1 years apart. Fat attenuation estimated fat quality.

Results

Mean weight change was +2.0 (SD 6.8; IQR -0.7, 5.0) kg in women and +2.7 (SD 6.0; IQR -0.5, 5.4) kg in men. Per 2.5 kg weight increase in women, VAT volume increased 126 cm(3) (95% CI, 112-140, p < 0.0001), SAT volume increased 258 cm(3) (95% CI, 239-278, p < 0.0001), and fat attenuation dec
