Table 4 Factors associated with future enrolment in the DMP. Results from logistic regression analysis (n = 836)

From: Selection effects may account for better outcomes of the German Disease Management Program for type 2 diabetes

Variable Odds ratio 95% confidence interval p*
Age: 60 vs. 70 years 1.12 0.91 to 1.37 0.254
Gender: men 1.09 0.71 to 1.68 0.681
Duration of diabetes: 10 years vs. 1 year 1.02 0.99 to 1.05 0.125

Smoking behaviour: non-smoking 1.97 1.11 to 3.48 0.021

Systolic BP value: 120 vs. 160 mmHg 1.79 1.15 to 2.81 0.012
Oral medication** 2.17 1.35 to 3.49 0.002
Blood glucose self-monitoring 1.69 1.03 to 2.76 0.038
Urinary glucose self-monitoring 2.96 0.92 to 9.47 0.067
Prescription of diabetes education program before DMP start 2.32 1.29 to 4.19 0.006
GP-rated motivation of the patients: high vs. low (3 vs. 1 on a 3-point scale) 4.55 2.21 to 9.36 < 0.001
Diabetes education activity of the GP 1.23 0.71 to 2.14 0.456
  1. * Statistically significant results (p ≤ 0.05) in italic and bold letters.
  2. ** Insulin treatment was dropped from the statistical model in favour of blood glucose self-monitoring because of high correlation between these two variables (r2 > 0.5) and blood glucose self-monitoring being the better predictor for enrolment.
