Abstract:
Objective To assess the diet quality of pregnant women during the second trimester using the dietary inflammatory index ( DII) and to explore the correlation between the DII in second trimester of preg-nancy and preterm delivery.Methods A total of 253 women with singleton pregnancy in 16-20 gestational weeks who had received routine prenatal care between August 2014 and April 2015 at the First Affiliated Hospi-tal of Anhui Medical University were enrolled with cluster random sampling.The included women were asked to recall daily dietary intake in the 3 days prior to the survey.All dietary data were analyzed for energy and nutri-ents intake with a nutritional analysis software, followed by calculation of DII according to previous reports. Based on quartiles of the DII scores, the participants were divided into three groups, namely the anti-inflam-matory group (DII<-5.10), intermediate group (DII -5.10--2.55), and the pro-inflammatory group (DII>-2.55).The participants were followed up until delivery and the pregnancy outcomes were recorded. The relationship between the DII in second trimester of pregnancy and preterm delivery were analyzed. Results DII scores of the 253 pregnant women during the second trimester of pregnancy ranged from -7.913 to 3.872.The risks of preterm birth in the anti-inflammatory diet group, the intermediate group, and the pro-inflammatory diet group were 0, 1.6%, and 6.3%, respectively, with statistically significant differences among the groups (P=0.034).The higher DII scores (pro-inflammatory) were associated with higher inci-dence of preterm birth ( P<0.05 ) .Conclusion DII may be used to assess diet quality of pregnant women during the second trimester and to predict the risk of preterm birth.
