Abstract：Objective:To analyze the risk factors related to neonatal asphyxia and construct a Nomogram prediction model.Methods:The clinical data of 230 newborns delivered in the hospital from May 2020 to April 2022 were retrospectively analyzed and divided into an observation group(n=11)and a control group(n=219)according to whether asphyxia occurred.The clinical data of the two groups were statistically analyzed,and the receiver operating characteristic(ROC)curve was used to analyze the statistically significant continuous variables.The multivariate logistic regression model was used to analyze the independent risk factors of neonatal asphyxia.The R software was used to construct a Nomogram prediction model for predicting neonatal asphyxia.The calibration curve was used to verify the Nomogram prediction model internally.The decision curve was used to evaluate the clinical net benefit of the model.Results:The maternal age in the observation group was higher than that in the control group.The proportion of premature infants,abnormal fetal position,abnormal pregnancy history,premature rupture of membranes,threatened abortion history,primiparity,and gestational hypertension in the observation group were higher than those in the control group(all P＜0.05).The area under the curve(AUC)of maternal age was 0.829,and the optimal cutoff value was 35 years old.Maternal age(i35 years old),premature infants,abnormal fetal position,primiparity,and gestational hypertension were independent risk factors for neonatal asphyxia(P＜0.05).Conclusions:This study constructed a Nomogram prediction model for neonatal asphyxia risk factors based on maternal age,premature infants,abnormal fetal position,primiparity,and gestational hypertension,which is helpful for medical staff to recognize high-risk factors related to asphyxia,formulate personalized nursing countermeasures,and provide some reference for clinical prevention and treatment.
