What is a common risk factor for Pregnancy-Induced Hypertension (PIH)?

A previous history of preeclampsia is indeed a common risk factor for developing Pregnancy-Induced Hypertension (PIH), which is characterized by elevated blood pressure that occurs after 20 weeks of gestation. Women who have experienced preeclampsia in previous pregnancies have a higher probability of encountering similar complications in subsequent pregnancies. This is believed to be due to underlying vascular issues or predispositions that are carried over between pregnancies, making it crucial to monitor these individuals closely for signs of hypertension or other related complications.

In contrast, the other options do not align with established risk factors. Age between 25 and 30 is generally considered a lower risk period for such complications, while high socioeconomic status is often associated with better access to healthcare and healthier lifestyle choices, potentially lowering the risk of PIH. Lastly, having no prior history of diabetes or hypertension would typically indicate a lower risk profile rather than a contributing factor for PIH, as existing conditions could elevate the risk for developing hypertension during pregnancy.
