Characteristics of the Two Groups of Subjects.^*

Characteristic	Insulin-Sensitive Controls	Insulin-Resistant Subjects
Age (yr)	28±7	26±7
Weight (kg)	60±13	64±9
Height (m)	1.69±0.11	1.65±0.09
Body-mass index	21±2	23±2
Activity index†	2.6±0.5	2.4±0.4
Glycosylated hemoglobin (%)‡	5.1±0.3	5.2±0.4
Adipocyte-derived factors
Adiponectin (μg/ml)	12±4	11±4
Tumor necrosis factor α (pg/ml)	1.5±0.3	1.8±0.9
Interleukin-6 (pg/ml)	0.52±0.31	0.68±0.42
Resistin (ng/ml)	0.77±0.24	0.79±0.24

^*Plus–minus values are means ±SD. The body-mass index is the weight in kilograms divided by the square of the height in meters.

^†Values can range from 1.7 to 3.3, with higher values indicating greater activity.

^‡Values were measured after an overnight fast.
