  • After adjustment for confounders, women with inadequate plasma 25(OH)D concentrations (<75 nmol/L) had significantly higher increase in the concentration of low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and TC/high-density lipoprotein cholesterol (HDL-C) ratios throughout pregnancy.

Why this matters 

  • Increasing evidence shows that an abnormal lipid profile during gestation may increase the risk of cardiovascular disease.

Study design

  • This prospective study involving 194 pregnant women (mean age 26.7 y) evaluated the association between the first trimester 25(OH)D status and changes in serum lipid concentrations throughout pregnancy.
  • Funding: Research Foundation of the State of Rio de Janeiro.

Key results

  • 69% of women had inadequate concentrations of 25(OH)D at baseline.
  • At baseline, women with 25(OH)D inadequacy had higher mean LDL-C than those with adequate concentrations in the first trimester (91.3 vs. 97.5 mg/dL; P=.064).
  • Independent of 25(OH)D concentrations, TC, HDL...
