Introduction: Oxydative stress may cause preterm labor. Antioxidants found in fruit and vegetable prevent the oxidative stress reaction. In this study we intend to answer the question: Is any correlation between preterm delivery and use of fruit and vegetable before and during pregnancy?
Materials and Methods: It is a case control study in which 43 women with preterm delivery and 86 women with term delivery who delivered in Arak maternity hospital were selected randomly. (sample size was calculated with α=5%, β=20%). The two groups were matched for socioeconomic status, maternal age , gravid and vitamin supplement consumption. Data was collected with a questionnaire that includes demographic information, and use of fruit and vegetable (proportion in week ) during the three month before and second trimester in pregnancy. SPSS software and K-S, t (pooled), Mann-Whitney, Chi square and logistic regression were used to analyze the data.
Results: This study showed that the mean use of fruit and vegetable consumption calculated during the three month time before pregnancy was 20.64±2.48 in control group and 32.23±1.52 in case group and the relationship was significant (p<0.00001) and the mean.
Use during the second trimester was 21.84±4.75 and 34.84±5.58 in case and control groups respectively that was significant (p<0.00001). Accuracy, sensitivity and specificity of regression model were 90%, 87% and 91/9% respectively.
Conclusion: This study showed that fruit and vegetable consumption is related to the decreased incidence of preterm labor. Based on our model, preterm labor can be prevented and predicted with enough consumption of fruit and vegetables.
