Lipid and lipoprotein reference values from 133,450 Dutch Lifelines participants: Age- and gender-specific baseline lipid values and percentiles

BACKGROUND: Lipids and lipoproteins are recognized as the most important modifiable risk factors for cardiovascular disease. Although reference values for the major lipoproteins, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol, and triglycerides, have been collected in numerous studies and cohorts, complete contemporary percentile-based reference values are underreported.

OBJECTIVE: We set out to provide such reference lipid data using a large contemporary populationbased cohort study.

STUDY DESIGN AND SETTING: Lifelines is a cross-sectional population-based Dutch cohort study. We analyzed 133,540 adult fasting participants without cardiovascular disease and without lipid-lowering drug use. Lipid levels were directly measured and selected percentiles of all lipid parameters were calculated. Friedewald LDL-C estimation was calculated as well.

RESULTS: From 20 till 49 years of age, men were found to exhibit a steep 64% increase of LDL-C (median 154 mg/dL), while triglyceride levels increased almost 2-fold. In women, LDL-C levels did not change from 18 till 35 years, followed by a steep 42% increase till 59 years (median 142 mg/dL). In contrast to men, triglycerides were stable in ageing women. Overall, Friedewald LDL-C levels are lower compared with the direct measurement, especially with increasing triglyceride levels.

CONCLUSIONS: This observational study highlights striking gender- and age-related differences in plasma lipid profiles. The given reference ranges of plasma lipids can assist in early identification of individuals with hypocholesterolemia and hypercholesterolemia, especially familial hypercholesterolemia.
