Early pregnancy lipid concentrations and spontaneous preterm birth.
OBJECTIVE
Women who deliver preterm infants may be at increased risk for cardiovascular disease, perhaps related to dyslipidemia.


METHODS
In a nested case control study of women with spontaneous preterm birth, cholesterol, high-density lipoprotein, low-density lipoprotein, and triglycerides were evaluated. Lipid concentrations and gestational changes, as well as risk for preterm birth, were evaluated in women who delivered <34 (n = 23), >or=34-<37 (n = 67), and >or=37 weeks (n = 199).


RESULTS
High cholesterol or triglycerides <or=15 weeks were associated with a 2.8-fold (1.0-7.9) and 2.0-fold (1.0-3.9) increased risk for preterm birth <34 weeks and >or=34-<37 weeks, respectively. Overweight women who delivered <34 weeks had particularly elevated early pregnancy concentrations of cholesterol and low-density lipoprotein; lean women with moderate preterm birth had elevated triglycerides. There was a reduced triglyceride response in the first half of pregnancy among women who delivered <34 weeks.


CONCLUSIONS
Our results indicate the presence of dyslipidemia in women with spontaneous preterm birth.
