The Effect of Moringa Leaf Extract Intervention Since Preconception Period on the Prevention of Oxidative Stress in Pregnant Women and Adverse Pregnancy Outcomes

Background: Oxidative stress occurs due to an imbalance of oxidants and anti-oxidants and is often associated with poor pregnancy outcomes. Therefore, additional supplementation is needed since the preconception period to prevent oxidative stress and poor pregnancy outcomes. This study aims to examine the effect of supplementing Moringa leaf extract on the prevention of oxidative stress in pregnant women and poor pregnancy outcomes. Methods: This study is an observational study with a prospective cohort study design. The research subjects were third trimester pregnant women consisting of 2 groups, namely the control group who only received Iron-Folic Acid (IFA) supplements (n = 30) and the group that received moringa leaf extract and IFA supplements (n = 26). Then an examination of Malondialdehyde (MDA) levels as a biomarker of oxidative stress was carried out using the ELISA (enzyme-link immune sorbent) method, followed by pregnancy outcomes including birth weight and birth length. Data were analyzed by unpaired t test. Results: The results showed that there were no significant differences in the levels of MDA, birth weight and birth length in the two groups with a p value > 0.05. Nevertheless, MDA level in IFA group was 49.25 nmol/ml higher than Moringa + IFA group which was 47.58 nmol/ml. Likewise, the average of birth weight and birth length in Moringa group were 3042.3 grams and 48.62 cm higher than IFA group which were 2993.7 grams and 48.23 cm. Malondialdehyde levels were also higher in women who had babies with birth weight < 2500 grams was 49.48 nmol/ml and birth length < 48 cm was 49.13 nmol/l compared to birth weight ≥ 2500 grams was 48.50 nmol/ml and birth length ≥ 48 cm was 48.62 nmol/ml but there was no significant difference in the two groups (p>0.05). Conclusion: Oxidative stress in pregnant women tends to be associated with poor pregnancy outcomes. Moringa leaf extract supplementation since preconception can prevent increased oxidative stress and improve pregnancy outcomes.
