Abstract To analyze the effects of weight gain during pregnancy and blood lipid level of pregnant women with singleton on their adverse pregnancy outcomes and neonatal body composition. Methods: A total of 206 pregnancy women with singleton who underwent prenatal examination and delivery in the hospital were selected by convenient sampling method from June 2021 to June 2022. These women were divided into group A (women with good pregnancy outcomes) and group B (women with adverse pregnancy outcomes) according to the pregnancy outcomes of these women. The general data, the weight gain during pregnancy, and the blood lipid levels of the women were compared between the two groups. The influencing factors of the adverse pregnancy outcomes of the women in the two groups were explored by Logistic regression analysis. The weight gain during pregnancy, the status of blood lipid and the adverse pregnancy outcomes, and the situation of the newborn body composition, such as percentage of body fat and fat weight, of the women in the two groups were analyzed. Spearman correlation was used to analyze the correlation between the weight gain and the blood lipid status during pregnancy of the women and their newborn body composition. Results: Among 206 pregnant women, there were 37 cases in group B and 169 cases in group A. There were significant differences in the age, the pre-pregnancy body mass index (BMI), the weight gain during pregnancy, and the blood lipid levels of the women between the two groups (P＜0.05). Logistic regression analysis showed that the maternal age, the pre-pregnancy BMI, the pregnancy weight gain, and the dyslipidemia of the women were all the factors influencing their adverse pregnancy outcomes. After adjusting the confounding factors, such as age and pre-pregnancy BMI of the women, the pregnancy weight gain and the dyslipidemia of the women were still the independently correlated with their adverse pregnancy outcomes (all P＜0.05). The percentages of the body fat and the fat weight of the newborn of the women with excessive weight gain during pregnancy were significantly higher than those of the women with appropriate weight gain or insufficient weight gain during pregnancy, and which of the women with abnormal lipid metabolism were significantly higher than those of the women with normal lipid metabolism (all P＜0.05). Spearman correlation analysis showed that the weight gain and dyslipidemia of the women during pregnancy were positively correlated with the body fat percentage and fat weight of their newborn (P＜0.05). Conclusion: The excessive weight gain and abnormal lipid metabolism during pregnancy of the women with singleton pregnancy are the risk factors of their adverse pregnancy outcomes, and which will adversely affect the neonatal body composition of the women. So, the management of weight and blood lipid during pregnancy should be strengthened for controlling the weight gain and the blood lipid level of the women during pregnancy.
