The following have been identified as risk factors for placenta previa: Previous placenta previa (recurrence rate 4–8%), [13] caesarean delivery, [14] myomectomy [10] or endometrium damage caused by D&C. [13] Women who are younger than 20 are at higher risk and women older than 35 are at increasing risk as they get older.
Placenta accreta risk factors include placenta previa, abnormally elevated second-trimester AFP and free β-hCG levels, and advanced gestational parent age, specifically over the age of 35. [ 55 ] [ 56 ] Furthermore, prior cesarean delivery is one of the most common risk factors for placenta accreta, due to the presence of a uterine scar ...
An important risk factor for placenta accreta is placenta previa in the presence of a uterine scar. Placenta previa is an independent risk factor for placenta accreta. Additional reported risk factors for placenta accreta include maternal age and multiparity, other prior uterine surgery, prior uterine curettage, uterine irradiation, endometrial ablation, Asherman syndrome, uterine leiomyomata ...

[8] [18] The IOM guidelines were created from data mostly consisting of white women, and thus may not be an appropriate measure for women of other races/ethnicities. [ 8 ] African American women in general may have higher postpartum cardio-metabolic risk and more excess gestational weight gain than Latina women, who in turn have more than white ...
New guidelines set by the American College of Obstetricians and Gynecologists emphasize that pregnancy risks should be characterized in five-year age groups—like ages 35–40, 40–44, et cetera ...
Fetal macrosomia, maternal obesity and excessive weight gain during pregnancy are associated with later obesity in childhood and adolescence. [7] As early as at age 6 years, children of women who were obese before they became pregnant had more often a cardiometabolic risk profile compared to children of normal-weight mothers. [8]
Obesity prior to pregnancy and maternal weight gain above recommended guidelines during pregnancy are another key risk factor for macrosomia or LGA infants. [ 21 ] [ 22 ] [ 23 ] It has been demonstrated that while maternal obesity and gestational diabetes are independent risk factors for LGA and macrosomia, they can act synergistically, with ...
