Background; the body mass index (BMI) is frequently used to classify the severity of obesity and to inform weight-gain guidelines throughout pregnancy.
Aim and objectives; to evaluate the impact of BMI of nulliparous females on progress of labour, incidence of peri-partum complications (1ry outcome) and neonatal outcome of these women (secondary outcome).
Subjects and methods; This is a prospective cohort study, was carried out on 330nulliparous patients attending the labor ward of Al-Hussein and Sayed Galal hospitals, Al-Azhar University, Egypt, during active phase of labor, divided into 4 groups, from January 2021 until the end of the specified cases.
Result; In terms of weight and BMI, there is a considerable disparity between the 4 groups.
Conclusion; Labor development and labor time varied by BMI category, as evaluated by cervical dilatation rates. As per recent research, a higher BMI in nulliparous women is linked to a higher chance of caesarean birth during labor. This training should be available to first-time mothers prior to conception, and labor ward staff should be informed of this group of women before labour, with a concentration on the issues of analgesia and anesthesia in obese parturients.
