Correlation Analysis Of Body Mass Index And Age In Early Pregnancy With Pregnancy Related Complications And Neonatal Weight

Objective: To explore the relationship between pregnancy related complications and neonatal weight with body mass index (BMI) and maternal age in early pregnancy. Methods: Related information about 2,070 cases of primipara with single birth delivered in the obstetrics department of our hospital was analyzed. These above subjects were grouped according to their BMI and age. Relationship between pregnancy related complications and neonatal weight with BMI and mother's age in early pregnancy was further investigated. Results: BMI increased less in the overweight group than in the normal group and low weight group during pregnancy (P < 0.05). The overweight and obese group had a higher incidence of gestational hypertension and diabetes mellitus in early pregnancy than the normal group (P < 0.05). Besides, the average neonatal weight of the obese group was higher than that of the normal group (P < 0.05). The incidence of gestational diabetes mellitus in the senior age group was higher than that in the younger age group (P < 0.05). Logistic regression showed that being overweight, obese and older age were all risk factors related to pregnancy complications and low birth weight. Conclusion: Pregnancy related complications and outcomes are closely related to BMI and mother's age in early pregnancy.
