Abstract:
To analyze the types of dietary patterns of women during pregnancy in Shaanxi and their association with adverse pregnancy outcomes. Methods Data were derived from a cross?sectional program named "The prevalence and risk factors of birth defects in Shaanxi Province" from July to November in 2013. A multi?stage stratified random sampling method was used to extract 15 980 women of childbearing age who met the inclusion exclusion criteria from Shaanxi Province. The questionnaire obtained information such as the pregnancy outcome and the food intake of the study subjects during pregnancy. The dietary pattern was extracted by factor analysis, and the each dietary pattern of subjects were divided into T1-T3 groups according to the factor score. The effects of each dietary pattern on major adverse pregnancy outcomes were estimated by unconditional logistic regression model. Results Four dietary patterns were established: vegetarian pattern, balanced pattern, traditional pattern, and processing pattern. The multivariate logistic regression model results showed that compared with the vegetarian pattern T2 group, the T1 group had lower risk of low birth weight (OR=0.56, 95%CI : 0.41-0.83), and the T 3 group had higher risk of low birth weight in offspring ( OR=2.32, 95%CI : 1.59-3.89); compared with the traditional pattern T2 group, the T3 group had higher risk of premature (OR=2.62, 95%CI :1.58-5.01); compared with the balanced pattern T2 group, the T3 group had a lower risk of spontaneous abortion (OR=0.73, 95%CI: 0.36-0.89); compared with the processing pattern T2 group, the T3 group had a higher risk of spontaneous abortion ( OR=1.97, 95%CI : 1.36-3.34) and higher risk of stillbirth ( OR=2.96, 95%CI : 1.49-6.26), and the T 1 group had a lower risk of stillbirths in offspring ( OR=0.52, 95%CI :0.33-0.83). Conclusion The women of childbearing age in Shaanxi have different dietary patterns, and there may be a correlation between dietary patterns and adverse pregnancy outcomes.
