Table 2 Multivariate Logistic Model Results - Variables and Odds of Sustained Weight Loss Success Compared to Base Case PwOa

From: Predictors of weight loss outcomes in obesity care: results of the national ACTION study

Variable Type Variable Description Variable Specificationb Coefficient (Standard Error) Odds Ratio and 95% Confidence Interval PwO Affected
Intercept N/A Constant −3.67 (0.4847) N/A N/A
Demographic Weight History 1 year ago Continuous −0.01 (0.0026)*** 0.99 (0.99–1.00)c Mean = 248lbs
Demographic Weight History 10 years ago Continuous −0.02 (0.0021)*** 1.02 (1.01–1.02) Mean = 221lbs
Demographic Formal diagnosis of obesity No, Not sure [2, 3] - > 1
Yes [1] - > 0
−0.45 (0.1902)* 0.64 (0.44–0.92) No/Not sure [2, 3] = 44%
Attitudinal When discussing your weight with your HCP, how often do they recognize your previous weight management efforts? Often [4, 5] - > 1
Not often [1,2,3] - > 0
0.69 (0.1687)*** 1.99 (1.43–2.77) Often [4, 5] = 39%
Attitudinal Attitudes toward weight loss: I am motivated to lose weight Agree [4, 5] - > 1
Do not agree [1,2,3] - > 0
0.59 (0.1746)*** 1.81 (1.28–2.54) Agree [4, 5] = 45%
Attitudinal Barriers to initiating a weight loss effort: my lack of motivation Agree [4, 5] - > 1
Do not agree [1,2,3] - > 0
−0.49 (0.1699)** 0.61 (0.44–0.86) Agree [4, 5] = 52%
Behavioral HCPs discussed weight with/would discuss weight with: diabetes educator Yes [1] - > 1
No [2] - > 0
0.20 (0.2317) 1.22 (0.78–1.93) Yes [1] = 10%
