Before initiating oral combined hormonal contraception in a 15-year-old female, which assessment is essential?

Before starting oral combined hormonal contraception in a 15-year-old female, measuring blood pressure is essential due to the potential risk of cardiovascular complications associated with the use of these contraceptives. Hormonal contraceptives can increase the risk of hypertension, which may lead to serious health issues, including stroke and heart disease, especially in users with pre-existing high blood pressure.

The American College of Obstetricians and Gynecologists recommends blood pressure measurement as a routine part of evaluating a patient's suitability for hormonal contraception. This guideline is particularly crucial for adolescents since this age group may not have regular medical check-ups, and undiagnosed hypertension can be more prevalent.

While weight, serum glucose, and lipid profiles can be important in different contexts, they are not universally required before initiating combined hormonal contraception. Blood pressure is prioritized due to its direct impact on cardiovascular risk related to hormonal contraceptive use.
