Summary
Objective: The aim of this study is to determine the effects of zinc supplementation on biomarkers of inflammation and oxitative and pregnancy outcomes in gestational diabetes. Study design: Double-blind randomized controlled clinical trial. Inclusion and Exclusion Criteria: Pregnant women aged 18-40 years diagnosed with GDM at 24-28 weeks' gestation will be included in this study. The use of substitute treatments including hormone or vitamin supplements as well as those with preeclampsia, complete bed rest (CBR), intra uterine fetal death (IUFD), placenta abruption and preterm delivery will be excluded in the study. Population and sample size: 50 patients with GDM among pregnant women of eligible and referred to Naghavi Clinic affiliated to Kashan University of Medical Sciences, Kashan, Iran in the study will be selected. Intervention: Patients will be assigned to receive either zinc supplement (intervention group: n=25) or placebo (control group: n=25). Although the intervention will be done for 6 weeks, all participants will be followed until delivery. Start and End Date of Intervention: 5 months (December 5, 2014-May 10, 2015). Outcomes: High-sensitivity C-reactive protein (hs-CRP), nitric oxide (NO), plasma total antioxidant capacity (TAC) and total glutathione (GSH) at study baseline and end-of-trial will be measured. Infants' weight, length, head circumference, 5-min Apgar score and ponderal index will be measured.
