Introduction:The incidence of grand multiparty in Saudi Arabia is high; there are no adequate studies about the grand multiparty.Aim:The aim to determine the prevalence, fetal and maternal outcomes in grand multipara women in comparison to primipara’s women.Methods:A retrospective study, the data was collected from our hospital records of labour and delivery unit started from January 2016 to December 2016.Results:The analysis was done in 415 charts divided into two group 1 consist of (120 primigravidas) used as the control and group 2 the study group (295 grand multiparas). When comparing the maternal age between the two groups, grand multipara was older (mean of 36.9 ± 4), and primigravida age (33.5 ± 5.7) with a p-value < 0.001. The fetal weight, Gestational age, and Apgar score at 1, and 5 min, the type of delivery, medical disease are common in grand multipara and statistically significant P<0.001. However, HTN is more common in primigravida but not statistically significant with P value <0.287. Premature rupture of membrane. Intrauterine growth retardation breech presentation and preterm labour, Placental abnormality and postpartum haemorrhage more common in grand multipara and statistically significant a p-value < 0.001. The neonatal outcome, ICU admission, intrauterine fetal death all were similar in each group, not statistically significant. Logistic regression performed of a different variable.Conclusion:Grand multipara is common in our institution and the outcome of medical diseases, and obstetrical complication is more in grand multipara than primigravida.
