Association of physical activity and visceral adipose tissue in older XXXX and @entity1 .

@entity1 @entity43 @entity6 @entity5 @entity4270 @entity65
OBJECTIVE: Physical inactivity, abdominal fat, and age are known risk factors for @entity6 , @entity65 , and certain @entity5 . Previous evidence supports an inverse relationship between physical activity (PA) and abdominal fat estimated by waist circumference. However, few investigations used computed tomography (CAT) scanning for precise measures of abdominal fat. RESEARCH METHODS AND PROCEDURES: Sixty-five female and 106 male (age, 64.5 +/- 5.2 years) @entity1 in the Prostate, Lung, Colon and @entity43 Screening Trial underwent a cross-sectional L4-L5 CAT scan to differentiate visceral adipose tissue (VAT). Subjects were also interviewed by phone to determine PA and @entity4270 ( @entity4270 ). RESULTS: @entity1 had lower VAT (170 +/- 84 vs. 205 +/- 95 cm(2), p = 0.014), lower VAT/total fat (29.9 +/- 7.2% vs. 42.6 +/- 10.2%, p < 0.001), and higher total fat (596 +/- 385 vs. 482 +/- 183 cm(2), p = 0.010) than @entity1 . PA was inversely correlated to VAT (r = -0.164, p = 0.034) and total fat (r = -0.231, p = 0.003) in @entity1 and @entity1 . Those who reported a @entity4270 had higher VAT (249 vs. 180 cm(2), p < 0.001) and total fat (652 vs. 500 cm(2), p = 0.008). Multiple regression analysis indicated total PA and @entity4270 were independently associated to VAT and total fat. DISCUSSION: This investigation suggests a beneficial effect of PA and a negative influence of @entity4270 on abdominal fat accumulation. Although the cross-sectional design limits cause-effect designations, these results are consistent with other studies showing PA/abdominal fat relation.
