Which of the following is not associated with an increased incidence of postdural puncture headache?

• A. Young age
• B. Female gender
• C. Early ambulation
• D. Pregnancy

Answer: (C)

PDPH risk is shaped by patient characteristics that affect how easily CSF leaks and how the body tolerates that leak. Younger patients tend to have a higher incidence because the dura and CSF dynamics favor a more persistent leak after puncture. Female gender is another risk factor, with hormonal and tissue differences thought to contribute to greater susceptibility. Pregnancy further increases risk, likely due to hormonal effects on connective tissue and higher venous pressures during pregnancy. Early ambulation, however, does not raise the likelihood of developing PDPH. The CSF leak from a dural puncture occurs regardless of whether the patient moves or stays still, and current evidence doesn’t show that getting up soon after puncture increases incidence. Movement may affect symptom severity more than the chance of occurrence. So, the option that is not associated with an increased incidence is early ambulation.
