Serum lipids and lipoproteins in Chinese men and women.

BACKGROUND Because of rapid change in lifestyle risk factors, cardiovascular disease has become the leading cause of death in China. We sought to estimate the national levels of serum lipids and lipoproteins among the Chinese adult population. METHODS AND RESULTS We conducted a cross-sectional study in a nationally representative sample of 46 239 adults aged ≥20 years. Fasting serum total, high-density lipoprotein, and low-density lipoprotein cholesterol and triglycerides were measured by standard methods. The age-standardized estimates of total, high-density lipoprotein, and low-density lipoprotein cholesterol and triglycerides were 4.72 (95% confidence interval, 4.70-4.73), 1.30 (1.29-1.30), 2.68 (2.67-2.70), and 1.57 (1.55-1.58) mmol/L, respectively, in the Chinese adult population. In addition, 22.5% (21.8-23.3%) or 220.4 million (212.1-228.8) Chinese adults had borderline high total cholesterol (5.18-6.21 mmol/L), and 9.0% (8.5-9.5%) or 88.1 million (83.4-92.8) had high total cholesterol (≥6.22 mmol/L). The population estimates for borderline high (3.37-4.13 mmol/L), high (4.14-4.91 mmol/L), and very high (≥4.92 mmol/L) low-density lipoprotein cholesterol were 13.9% (13.3-14.5%) or 133.5 million (127.0-140.1), 3.5% (3.3-3.8%) or 33.8 million (31.2-36.5), and 3.0% (2.8-3.3%) or 29.0 million (26.3-31.8) persons, respectively. In addition, 22.3% (21.6-23.1%) or 214.9 million (207.0-222.8) persons had low high-density lipoprotein cholesterol (<1.04 mmol/L). The awareness, treatment, and control of borderline high or high total cholesterol were 11.0%, 5.1%, and 2.8%, respectively, in the Chinese adult population. CONCLUSIONS Serum total and low-density lipoprotein cholesterol levels were high and increasing in the Chinese population. Without effective intervention, atherosclerotic cardiovascular diseases may soar in the near future in China.
