The maternal age groups that are at higher risk for developing pregnancy-induced hypertension (PIH) are indeed those who are between 18-25 years old and over 35 years old. Younger mothers in this age range might have increased stress on their bodies, which can contribute to PIH. Additionally, advanced maternal age, particularly over 35, is associated with various risk factors including pre-existing health conditions, decreased vascular adaptation during pregnancy, and potential dietary and lifestyle factors that can influence blood pressure regulation.

While the other age group combinations suggest potential risks, they do not capture the well-documented associations of PIH with the specific younger and older maternal age extremes as effectively as the chosen option does. It is essential in obstetric care to monitor these age groups closely for signs of PIH, allowing for appropriate management and intervention strategies that can improve maternal and fetal outcomes.
