Fasting insulin has been used as a surrogate measure of insulin sensitivity in studies of non-insulin-dependent diabetes mellitus (NIDDM) risk, but the fasting insulin-NIDDM association may be confounded by insulin secretion, which correlates negatively with NIDDM risk and positively with fasting insulin level.
In a prospective 5-year study of 137 nondiabetic Japanese-American men in King County, Washington State, higher fasting insulin was not strongly related to NIDDM (odds ratio (OR)=1.37,95% confidence interval (CI) 0.80-2.34), but this odds ratio increased substantially after adjustment for insulin secretion (OR=2.92,95% CI 1.41-6.06).
Research on NIDDM risk in relation to fasting insulin may yield biased effect measures unless adjusted for insulin secretion.
