Abstract

OBJECTIVE: To compare the effects of weight loss vs aerobic exercise training on coronary artery disease risk factors in healthy sedentary, obese, middle-aged and older men. DESIGN: Randomized controlled trial. SUBJECTS: A total of 170 obese (body mass index, 30 +/- 1 kg/m2 [mean +/- SEM]), middle-aged and older (61 +/- 1 years) men. INTERVENTIONS: A 9-month diet-induced weight loss interventions, 9-month aerobic exercise training program, and a weight-maintenance control group. MAIN OUTCOME MEASURES: Change in body composition, maximal aerobic capacity (V02 max), blood pressure, lipoprotein concentrations, and glucose tolerance. RESULTS: Forty-four of 73 men randomized to weight loss completed the intervention and had a 10% mean reduction in weight (- 9.5 +/- 0.7 kg; P < .001), with no 22 change in VO2 max. Forty-nine of 71 men randomized to aerobic exercise completed the intervention, increased their VO2 max by a mean of 17% (P < .001), and did not change their weight, whereas the 18 men who completed in the control group had no significant changes in body composition or VO2 max. Weight loss decreased fasting glucose concentrations by 2%, insulin by 18%, and glucose and insulin areas during the oral glucose tolerance test (OGTT) by 8% and 26%, respectively (P < .01). By contrast, aerobic exercise did not improve fasting glucose or insulin concentrations or glucose responses during the OGTT but decreased insulin areas by 17% (P < .001). In analysis of variance, the decrement in fasting glucose and insulin levels and glucose areas with intervention differed between weight loss and aerobic exercise when compared with the control group (P < .05). Similarly, weight loss but not aerobic exercise increased high-density lipoprotein cholesterol levels (+ 13%) and decreased blood pressure compared with the control group. In multiple regression analyses, the improvement in lipoprotein and glucose metabolism was related primarily to the reduction in obesity. CONCLUSIONS: These results suggest that weight loss is the preferred treatment to improve coronary artery disease risk factors in overweight, middle-aged and older men.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
