The National Health and Nutrition Examination Survey (NHANES) reported declining blood cholesterol values from 1999 through 2010. In the absence of more recent published data, we examined LDL-C values from a single clinical laboratory database to determine whether these values continued to decline through 2011.\\n\\nMETHODS AND RESULTS: We extracted almost 247 million LDL-C results from nearly 105 million adults who received diagnostic testing from a single national clinical laboratory. Annual age-adjusted mean LDL-C values were calculated, and analyzed by gender. Piecewise regression analysis of the total study population indicates a breakpoint, or change in slope, in the years following 2008 (F = 163.13; p<0.05). Between 2001 and 2008, the average rate of annual decline was -2.05 mg/dL (95% CI [-2.35, -1.75]). After 2008, mean LDL-C levels flattened out, with a slope not statistically different from zero (slope = -0.10 mg/dL/year; 95% CI [-1.46, 1.26]). This stabilization was observed in both genders and all age ranges, and was also reflected in the percentage of results in low- and high-risk categories.\\n\\nCONCLUSIONS: The trends reported suggest historical progress in decreasing LDL-C levels, observed from 2001-2008, may have stalled in recent years. Further research is needed to determine the cause of the observed trends and develop new strategies to reduce lipid-based cardiovascular risk further.", "link"=>"http://www.mendeley.com/research/blood-cholesterol-trends-20012011-united-states-analysis-105-million-patient-records", "reader_count"=>12, "reader_count_by_academic_status"=>{"Unspecified"=>2, "Librarian"=>1, "Researcher"=>3, "Student > Ph.
