Table 2 Incidence and odds ratios for the development of MS according to baseline insulin quartile in 5 years of follow-up in whole cohort

From: Elevated fasting insulin predicts the future incidence of metabolic syndrome: a 5-year follow-up study

  I(≤6.01)
(n = 592)
II (6.02-7.29)
(n = 585)
III(7.30-8.97)
(n = 588)
IV(≥8.98)
(n = 585)
Incident MS %(n) 3.9 (23/592) 5.1% (30/585) 8.5% (50/588) 16.4% (96/585)
Odds ratio (95% CI)
Model 1 1 1.4 (0.8 - 2.4) 2.5 (1.5 - 4.1) * 5.1 (3.1 - 8.2)*
Model 2 1 1.3 (0.7 - 2.4) 2.0 (1.2 - 3.4) † 3.6 (2.2 - 5.8)*
Model 3 1 1.2 (0.7 - 2.1) 1.7 (1.0 - 2.9) 3.0 (1.8 - 5.0)*
Model 4 1 1.1(0.6 - 2.1) 1.5 (0.9 - 2.5) 2.0 (1.2 - 3.3)†
  1. Adjusted factors in the models:
  2. Model 1: Gender, age, smoking status, exercise level, alcohol drinking amount, systolic blood pressure
  3. Model 2: Model 1 + HDL-cholesterol, triglyceride
  4. Model 3: Model 1 + HDL-cholesterol, triglyceride, fasting glucose
  5. Model 4: Model 1 + HDL-cholesterol, triglyceride, fasting glucose, waist circumference
  6. * p < 0.001
  7. p < 0.05
  8. MS, metabolic syndrome; HDL, high-density lipoprotein; CI, confidence interval
