Abstract
Background: Adverse perinatal outcome has always been a devastating experience for the mother. Advanced maternal age and other risk factors are independent risk factor for perinatal outcome. Therefore, aim of study is to compare the effect of these factor in different study group.

Aims and Objectives: Case–control study has been conducted to evaluate obstetrics outcome, maternal morbidity, and perinatal outcome in patients with bad obstetric history.

Materials and Methods: A prospective observational case–control study has been conducted in two groups; GROUP A: BOH group (n = 44) and GROUP B: Controls (n = 88) who fulfilled inclusion criteria in Department of Obstetrics and Gynaecology, GMERS Medical college, Sola during the period of August 2018 to August 2020. Statistical analysis was done by descriptive statistics and qualitative and quantitative method.

Results: Incidence of hypertension in Group A was 25%, while in Group B incidence was 6.8%. Incidence of hypertension was 4.5 times higher in Group A than B which was statistically significant (P < 0.05). Incidence of PROM, gestational diabetes mellitus, thyroid dysfunction was higher in Group A than Group B. Higher incidence of preterm delivery found in Group A than in Group B which was statistically significant (P < 0.05).

Conclusion: Among all BOH group, cases with previous history of preterm delivery, still birth, recognition of prior learning, and HTD were the major risk factors which could be responsible for adverse obstetric and perinatal outcome.
