The Practice Guideline Brief, “AHA diet and Lifestyle Recommendations,” (May 15, 2007, page 1573) contained an error in the fourth paragraph of the second column on page 1573. the levels of high-density lipoprotein cholesterol, considered by the American heart Association (AHA) as one of the criteria for classification of metabolic syndrome, were inadvertently switched for men and women. the sentence should have read as follows: “Although the AHA does not recommend specific goals for high-density lipoprotein cholesterol, levels lower than 40 mg per dL (1.04 mmol per L) for men and lower than 50 mg per dL (1.30 mmol per L) for women are criteria for metabolic syndrome.” the online version of this article has been corrected.
