[The levels and distribution of the serum lipids in Chinese adults, 2010].

OBJECTIVE

To study the levels of blood lipid among Chinese adults in 2010 and analyze the epidemiological features.

METHODS

Fasting serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) were determined for 90 395 subjects aged 18 and over who were selected by multi stage cluster random sampling method from 162 surveillance sites of 31 provinces of China mainland in 2010. After complex weighting, the differences of levels of serum total TC, TG, HDL-C and LDL-C were analyzed in different age, gender and geographic regions.

RESULTS

After complex weighting, the levels of serum TC in Chinese adults was (4.04 ± 1.08) mmol/L, with (3.86 ± 1.03), (4.29 ± 1.11) and (4.33 ± 1.09) mmol/L in the groups of 18 - 44, 45 - 59 and over 60 years old (F = 177.56, P < 0.01), respectively. The level of serum TC was (4.06 ± 1.09) mmol/L and (4.03 ± 1.07) mmol/L in males and females (F = 2.38, P > 0.05), respectively; (4.08 ± 1.13) mmol/L and (4.03 ± 1.06) mmol/L in urban and rural areas (F = 0.51, P > 0.05), respectively, and (4.13 ± 1.11), (4.03 ± 1.01) and (3.93 ± 1.11) mmol/L in areas of east, middle and west respectively (F = 2.56, P > 0.05). The levels of serum TG was (1.33 ± 1.28) mmol/L, with(1.26 ± 1.24), (1.48 ± 1.46) and (1.35 ± 1.05) mmol/L in the groups of 18 - 44, 45 - 59 and over 60 years old (F = 85.98, P < 0.01), respectively. The level of serum TG was (1.45 ± 1.48) mmol/L and (1.21 ± 1.01) mmol/L in males and females (F = 172.01, P < 0.01), respectively, (1.34 ± 1.26) mmol/L and (1.33 ± 1.28) mmol/L in urban and rural areas (F = 0.16, P > 0.05), respectively, and(1.30 ± 1.25), (1.35 ± 1.23) and (1.35 ± 1.36) mmol/L in areas of east, middle and west (F = 0.69, P > 0.05) respectively. The levels of serum HDL-C was (1.11 ± 0.31) mmol/L, with (1.09 ± 0.30), (1.13 ± 0.33) and (1.14 ± 0.33) mmol/L in the groups of 18 - 44, 45 - 59 and over 60 years old (F = 27.81, P < 0.01), respectively. The level of serum HDL-C was (1.08 ± 0.32) mmol/L and (1.14 ± 0.30) mmol/L in males and females (F = 178.66, P < 0.01), respectively, (1.11 ± 0.31) mmol/L and (1.11 ± 0.32) mmol/L in urban and rural areas (F = 0.09, P > 0.05), respectively, and (1.12 ± 0.32), (1.12 ± 0.31) and (1.09 ± 0.32) mmol/L in areas of east, middle and west (F = 1.06, P > 0.05) respectively. The levels of serum LDL-C was (2.27 ± 0.78) mmol/L, with (2.15 ± 0.74), (2.42 ± 0.80) and (2.46 ± 0.81) mmol/L in the groups of 18 - 44, 45 - 59 and over 60 years old (F = 129.84, P < 0.01), respectively. The level of serum LDL-C was (2.30 ± 0.78) mmol/L and (2.24 ± 0.78) mmol/L in males and females (F = 25.06, P < 0.01), respectively, (2.33 ± 0.82) mmol/L and (2.24 ± 0.76) mmol/L in urban and rural areas (F = 3.48, P > 0.05), respectively, and (2.35 ± 0.80), (2.25 ± 0.74) and (2.17 ± 0.77) mmol/L in areas of east, middle and west (F = 4.58, P < 0.05) respectively.

CONCLUSION

The levels of serum lipid of middle aged male, female after menopause and people living in eastern region were higher than other Chinese adults. Effective measures should be taken earlier to control serum lipid levels.
