Objective:

Recent evidence suggests that obesity affects placental development, leading to adverse pregnancy outcomes. Whether obesity affects the pathophysiology of placenta accreta spectrum (PAS) is unknown. Thus, the objective of this study was to evaluate if maternal pre-pregnancy body mass index (BMI) correlates with increased PAS grade severity.  
 

Study Design:

A multicenter retrospective cohort study of histopathologically confirmed PAS cases 1/1/2013 - 6/30/2022 at five New York academic institutions. Obstetrical and demographic variables were collected. The cohort was divided into two groups, obese (BMI ≥30 kg/m2) and non-obese (BMI < 30 kg/m2). Univariable analysis was performed comparing variables using chi square test for categorical and Student t-test/Wilcoxon rank sum for continuous data. An ordinal regression analysis was then performed adjusting for statistically significant obstetrical and demographic variables between the two groups, comparing median PAS grade. Finally, we divided the cohort by PAS grades and compared the median BMI in each group. 

Results:

A total of 401 cases of PAS were collected. Of these, 166 had a documented histopathological grade of PAS. There were 26 obese patients and 140 non-obese. Demographics are presented in Table 1. The proportion of Black and Hispanic individuals was greater in the obese group (30.8% vs. 14.5% and 11.5% vs 5.1%, respectively, p = 0.025). Individuals in the obese group had a significantly greater number of prior cesarean sections [2 (1,3) vs. 1 (1,2), p = 0.045]. There were no other differences between the two groups in social and obstetrical variables. For the primary outcome, there were no differences in median PAS grade between the obese and non-obese groups [1 (1,2) vs 1 (1,2) p=0.67, regression coefficient -0.35, 95%CI (-0.94-0.22]. Additionally, there were no differences in incidence of obesity and median BMI among the different grades of PAS (Table 2).

Conclusion:

There were no differences in both severity of PAS disease and incidence of PAS grade between obese and non-obese patients with histopathologically confirmed PAS.
