Several factors influence IGFBP-3 levels, including age, sexual development, nutrition, and hepatic and renal function. IGFBP-3 increases during early childhood and puberty and then decreases slightly in adult life. Levels of this binding protein decrease during fasting and chronic malnutrition. IGFBP-3 levels are decreased in hepatic failure and diabetes mellitus, but are increased in chronic renal failure.
