Multivariable-adjusted ORs (95% CIs) for the 15-year incidence of diabetes by abnormal (<42 bpm) HRR

Total population OR (95% CI)Stratified by fitness*
Low fitness OR (95% CI)High fitness OR (95% CI)
Model 1. Adjusted for age, race, and sex1.53 (1.01–2.31)3.54 (1.56–8.03)0.69 (0.38–1.25)
Model 2. Adjusted for model 1 + smoking status and BMI1.29 (0.84–1.99)3.43 (1.47–8.00)0.73 (0.40–1.34)
Model 3. Adjusted for model 2 + baseline fasting insulin1.15 (0.72–1.85)3.27 (1.34–7.94)0.60 (0.31–1.16)
  • * Low fitness is the highest quartile of age- and sex-specific heart rate at stage 2 (4 min) of the exercise test.
