Prevalence of maternal preconception risk factors: an Italian multicenter survey.

OBJECTIVES: Adequate preconception maternal health care is essential to reduce the risk of unwanted pregnancy outcomes and complications. Still, many women are exposed to a number of unhealthy risk factors both before and early in pregnancy. This study aimed to estimate the prevalence of a number of important preconception risk factors using data from a recent multicenter study in Italy. METHODS: The study was based on cross-sectional data from seven maternity clinics located in six different regions in Italy during the period January - June, 2012. Data on maternal preconception risk factors and characteristics were collected from 1,892 women who delivered healthy children and 320 women who were pregnant in the first trimester. RESULTS: About 97% of the women (n =2,212) were exposed to one or more preconception risk factors. The overall prevalence of the most essential maternal risk factors was as follows: 41% had a age ≥35 years, 36% mistimed or did not intend their pregnancy, 58% did not request a preconception health visit to their doctor, 76% did not use folic acid supplements before pregnancy, 26% smoked at the last menstrual period, 19% had a body mass index ≥25 kg/m2 before pregnancy, and 10% suffered from pregestational chronic diseases. The prevalence of certain variables varied between the maternity clinics. CONCLUSIONS: Many Italian women are exposed to a number of preconception risk factors that have been associated with adverse pregnancy complications and outcomes. More effective intervention programs to improve preconception health in Italian women are strongly needed.

Lutein administration to pregnant women with gestational diabetes mellitus is associated to a decrease of oxidative stress in newborns.

Oxidative stress (OS) is defined as an imbalance between pro- and antioxidant factors that can lead to cellular and tissue damage. Under condition of gestational diabetes, OS is exacerbated and can cause vascular dysfunction in the placenta, leading to fetal and perinatal complications. We investigated the oxidative status of diabetic pregnant women and of their babies. A group of those diabetic women received lutein, and another group did not receive anything. In order to verify a possible antioxidant function of lutein, we compared the OS values of the two groups. OS appeared lower in treated gravidas than in untreated ones; however, there was not a statistically significant difference between the two groups. As far as newborns are concerned, there was a significant difference of OS values between babies born to mothers treated with lutein and newborns to mothers untreated at 2 h of life. However, at 48 h, there was not a significant difference between the two groups. In conclusion, lutein administration during pregnancy significantly reduced neonatal OS at birth. Further studies are necessary to evaluate the effects of combined administration to mother and infants.
