Abstract

Background: Insulin-like growth factor-1 (IGF-1) is associated with obesity and aging, and was recently linked to metabolic syndrome (MetS) and insulin resistance. However, little is known about the relationship between IGF-1 and adiponectin (adiponectin), another marker of MetS. Methods: We measured the plasma IGF-1 and adiponectin levels of 3099 subjects (1869 males, 55.9. ± 10.8. y). We applied the Korean-modified International Diabetes Foundation (k-IDF) criteria for determination of, and risk assessment for, MetS. Results: K-IDF criteria-based MetS occurred in 37.0% (n = 1146) of patients. IGF-1 (91.5 vs. 97.3. ng/ml, p. < 0.001) and adiponectin (3.95 vs. 4.23. μg/ml, p. < 0.001) were significantly lower in MetS patients than without MetS. Lower IGF-1 was associated with increasing numbers of MetS abnormalities, independent of adiponectin (p for trend. < 0.001, F = 12.615, p. < 0.001 in ANCOVA). MetS prevalence in individuals with both high IGF-1 and adiponectin levels (6.7%, n = 206) was significantly lower than in other groups. Both high IGF-1 and adiponectin group was associated with reduced MetS risk after adjusting for other confounding factors (OR 0.694, 95% CI 0.493-0.977, p = 0.036). Conclusions: IGF-1 was associated with MetS independent of adiponectin in our study. The independent relationship between IGF-1 and MetS provides insight into the pathophysiologic mechanisms of MetS.
