Special Issue Information

Dear Colleagues,

Obesity in pregnancy is associated with serious adverse maternal and fetal effects, including infertility, gestational diabetes, preeclampsia, intrauterine fetal and neonatal death, neural tube defects and many other.  Because the prevalence of obesity in pregnancy has been steadily increased over the last few decades, its health impacts are much more serious. According to the World Health Organization, It has been estimated that overweight and obesity affect over 50 million women globally in upper and middle income countries. In the United States, a third of the women are obese and the yearly number of obese pregnant women exceeds 1 million.

Obesity-related hyperinsulinemia and subsequent hyperandrogenemia increase the risk of anovulatory cycles and the chance of conception decreases. Obesity is associated with increased risk of caesarian section, premature placental abruption, perineal tear, puerperal fever, severe puerperal infections, would healing complications, complications of obstetric anesthesia, postpartum hemorrhage, sepsis, obstetric shock, ICU admission and combined severe maternal morbidity and mortality. Maternal obesity is associated with long term overweight retention and its attendant long term morbidity with diabetes mellitus and cardiovascular risks. Maternal overweight and obesity are associated with increased risks for congenital malformations such as neural tube defects, cardiovascular risks, hydrocephaly, oral cleft and limb reduction anomalies.

In this special issue, leading scientists will be addressing emerging knowledge related to important challenges in evaluating, preventing and managing obesity in pregnancy, with focus on short and long term maternal risks, child risks, congenital malformations and pharmacological and non- pharmacological management.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Clinical and Experimental Obstetrics & Gynecology is an international peer-reviewed open access quarterly journal published by IMR Press.

Obesity, neural tube defects and folic acid—A complex relationship

Obesity is associated with twofold increased risk of neural tube defects (NTD). Research has repeatedly shown that about 70% of NTD are folic-acid dependent. Yet, there is controversy whether folic acid status is the main determinant of the increased risk of obesity-induced NTD. The rational for this review is to update and discuss the evidence on the link between obesity, folic acid and NTD, in an attempt to shed light on the question whether optimal folic acid dose schedule can mitigate this risk. During pregnancy maternal folate requirements increase by 5–10-fold, as folate is diverted towards the placenta and fetus, as well as supporting different maternal organs. Correspondingly, low maternal folate status has been associated with birth defects in fetal anatomical regions particularly sensitive to reduced folate intake including oral cleft, cardiovascular defects and NTD. A recent study has documented decreased placental folate transporter expression and activity in the first and second trimesters among obese mothers. This may explain the higher incidence on NTD in infants of obese women, as less folate may find its way to the developing fetus during the sensitive periods for creating NTD. Recent pharmacokinetic results indicate that steady state levels of folate are almost perfectly defined by the dose per lean body weight (LBW). The mean dose per kg LBW that would be expected to result in steady state serum folate level of > 15.9 nmol/L was identified as 0.0073 mg/kg LBW. A large study found no differences in dietary supplementations of folic acid, yet obese women exhibited lower median serum folate as well as lower mean serum B12 levels, but no differences in mean RBC folate levels. There was a negative correlation between increasing BMI and both serum folate and plasma B12. Future research will be needed to incorporate more fully, in addition to evidence of NTD, obesity and folic acid intake, also direct measurements of serum and RBC folate, as well as other confounders, in order to create a model that will shed light on these complex interactions.

Addressing optimal maternal weight and exercise during the preconception period and pregnancy
C.P. Moutos, V. Lozovyy, S.M. Clark
Clinical and Experimental Obstetrics & Gynecology    2020, 47 (5): 622-628.   DOI: 10.31083/j.ceog.2020.05.9041

Pregnancy is an opportunity for women to access the healthcare system and address their health needs. Before and during pregnancy, providers should emphasize assisting women in interventions aimed at establishing a healthy weight and exercise regimen and should tailor their guidance based on a woman's baseline level of fitness. Doing so will improve a woman's likelihood of pregnancy and improve outcomes if she does become pregnant. Our goal is to propose actions providers should take to improve a woman's understanding of and ability to manage her weight and exercise goals during the preconception and pregnancy periods.
