Background
The majority of pregnant women present an increase in lipids. To investigate the influence of the non-fasting state in the lipid and lipoprotein profile in pregnancy, we have aimed to assess the dynamic change of serum lipid and lipoprotein profile with serum glucose in pregnancy to contrast the differences between fasting and non-fasting state.
Methods
Forty-five pregnant women and 41 controls were included in our study. All serum samples were assayed for TC, TG, HDL-C, LDL-C, ApoB, ApoA-1, Lp(a), sdLDL, and Glu concentrations. The comparison between pregnant women and controls (fasting and 2 h after breakfast), differences of these measurement results at three point-in-time, the associations between the concentrations of serum lipid and some maternal and fetus characteristics was conducted with statistical analysis.
Results
Except Glu (
p
< 0.001), there were no significant differences of all lipids between three point-in-time in pregnant women (
p
> 0.1). The statistically higher levels were found in fasting TC (
p
= 0.003), TG (
p
= 0.019), LDL-C (
p
= 0.002), ApoB (
p
= 0.001), ApoA1 (
p
= 0.013) and sdLDL (
p
< 0.001) of pregnant women compared with controls. Besides, the statistically significances were also found in 2-h TC (
p
= 0.001), LDL-C (
p
= 0.001), ApoB (
p
< 0.001), Glu (
p
= 0.013), ApoA-1 (
p
= 0.009) and sdLDL (
p
< 0.001) of pregnant women compared with controls. Otherwise, in non-fasting status (2 h after breakfast), pregnancy complication was relevant to TC (
p
= 0.041), HDL-C (
p
= 0.014), Glu (
p
= 0.004). Delivery mode was relevant to TC (
p
= 0.012), HDL-C (
p
= 0.013), LDL-C (
p
= 0.026), ApoA-1 (
p
= 0.012), and sdLDL (
p
= 0.044). BMI was relevant to TG (
p
= 0.027).
Conclusion
We have suggested the non-fasting lipids detection can be used for estimate lipid metabolism in pregnant women.
