Monitoring maternal triglyceride concentrations during pregnancy could be useful in reducing perinatal mortality.

We read with great interest the article by Sauvegrain et al. entitled "Understanding high rates of stillbirth and neonatal death in a disadvantaged, high-migrant district in France: a perinatal audit".¹ This well-designed study confirmed again that maternal overweight/obesity increases perinatal mortality. We would like to address some points that merit further attention. The intrauterine environment can affect the long-term health of the offspring has been widely accepted. Maternal high pre-pregnancy body mass index (BMI) increases the risks of fetal exposure to higher maternal triglyceride levels during the first trimester.
