Twelve-Month Changes in Adiposity and Metabolic Indicators Among 301 Individuals Randomized to a Lifestyle Weight Loss Intervention Group or to an Enhanced Usual Care Group

Variable Lifestyle weight loss group Enhanced usual care group
Glucose level, mg/dL −4.3 −0.4
Insulin level, μU/mL −6.5 −2.7
HOMA IRa −1.9 −0.8
Body weight, kg −7.2 −1.4
Weight lost, percentage −7.3 −1.3
Waist circumference, cm −5.8 −0.8
Body mass indexb −2.1 −0.3

Note. Values represent within-group differences that were based on analysis of covariance, controlling for baseline values. All between-group differences in change are statistically significant (ie, P < .001 for all comparisons). HOMA IR, homeostasis index ratio.

a

Calculated as the fasting insulin level times the fasting glucose level, divided by 22.5.

b

Calculated as the weight in kilograms divided by the square of the height in meters.
