Abstract 15587: Trends in High Ldl-Cholesterol Prevalence, Awareness, Treatment and Control Among Us Adults
Awareness, treatment and control of high LDL-cholesterol increased markedly during the late 1990s and early 2000s. It is unknown whether these trends have continued through 2010. We analyzed data on 11,308 US adults from serial US National Health and Nutrition Examination Surveys (1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, 2009-2010) to determine the prevalence of high LDL-cholesterol and awareness, treatment and control of this condition. LDL-cholesterol was measured after an overnight fast and high LDL-cholesterol and controlled LDL-cholesterol were defined using cut-points from the 2004 updated ATP-III guidelines. Awareness and treatment of high cholesterol were defined using self-report. Among US adults, the prevalence of high LDL-cholesterol did not change from 1999-2000 (37.2%) through 2009-2010 (37.8%). Awareness of high LDL-cholesterol increased from 48.9% in 1999-2000 to 62.8% in 2003-2004 but did not increase further through 2009-2010 (61.5%). Among those aware of having high LDL-cholesterol, treatment increased from 41.3% in 1999-2000 to 72.6% in 2007-2008 and was 70.0% in 2009-2010. Among all US adults with high LDL-cholesterol, control rates increased from 1999-2000 (9.1%) to 2005-2006 (26.7%) but did not increase further by 2009-2010 (27.4%). A similar pattern was observed for LDL-cholesterol control amongst treated individuals; 45.0%, 65.3% and 63.6% of treated individuals had controlled LDL-cholesterol in 1999-2000, 2005-2006, and 2009-2010, respectively (Figure). In conclusion, the prevalence of high LDL-cholesterol awareness has not increased since 2003-2004 and despite increasing treatment, the prevalence of LDL-cholesterol control among US adults has been stagnant since 2005-2006. Additional efforts are needed to increase the awareness, treatment and control of high LDL-cholesterol among US adults.
