Abstract:
Maternal obesity increases the risk of preterm delivery. Obesity is known to be associated with altered lipid metabolism. Objective To investigate the associations between high maternal triglyceride (mTG) levels during early pregnancy and risks of preterm delivery stratified by early pregnancy body mass index (BMI). Design Retrospective cohort study. Setting University-based maternity center. Patients 49,612 women with singleton pregnancy who underwent fasting serum lipid screening during early pregnancy. Main Outcome Measures Risk of preterm delivery (total, & lt;37 weeks; early, 28 to 33 weeks; and late, 34 to 36 weeks). Results Among women enrolled, 2494 had a preterm delivery, including 438 early preterm and 2056 late preterm delivery. High mTG ( & gt;90th percentile, 2.04 mM) was associated with shortened gestation. Risks of total, early, and late preterm deliveries increased with mTG levels, and the high mTG–related risk was highest for early preterm delivery [adjusted odds ratio (AOR) 1.72; 95% CI, 1.30 to 2.29]. After stratification by BMI, high mTG was associated with risk of preterm delivery in both overweight or obese (OWO) women (AOR 1.32; 95% CI, 1.02 to 1.70) and women with normal BMI (AOR 1.36; 95% CI, 1.16 to 1.59). In additional sensitivity analyses, we found that high mTG was related to higher risks of preterm delivery among OWO women and women with normal BMI (AOR, 1.54; 95% CI, 1.07 to 2.22 and 1.62, 1.34 to 1.96, respectively), especially early preterm delivery (AOR 2.47; 95% CI, 1.19 to 5.10, and AOR 2.50; 95% CI, 1.65 to 3.78, respectively). Conclusions High mTG level during early pregnancy increased the risks of preterm delivery not only in OWO women but also in women with normal BMI.
